DIY cyclone with reverse cone. Do-it-yourself vacuum cleaner with a cyclone filter for the workshop

During processing wooden blanks Everyone has probably encountered the fact that everything around them is covered with a large amount of shavings, sawdust and wood dust. To at least partially get rid of them, various dust collectors, chip suckers, filters and other devices are used. Many power tools and machines have their own dust collectors, while others have special outlets for connecting a vacuum cleaner.

In home workshops it would be better to use special ones. vacuum cleaner than a household one. Firstly, the engine is special. The vacuum cleaner is designed for more than long-term operation, and secondly, as a rule, it is equipped with a hose with a length of 3 m, which significantly simplifies its use with power tools. And yet, the downside of every vacuum cleaner is a small container for garbage.

How to make a cyclone filter with your own hands

Having set out to somehow simplify the work of cleaning a vacuum cleaner and reduce the cost of bags, I began to collect information on this issue. Found a description on the Internet different types simple devices in the form of intermediate dust collectors for a vacuum cleaner. Firstly, these are dust collectors in the form of a mini-cyclone. They perform their function well in collecting dust in a separate container, preventing it from getting into the vacuum cleaner, which increases the service life of the bags tens of times. The process of cleaning the dust collector from debris is also simplified. Ready-made devices are sold through online stores, but their cost is quite high with a very simple design.

Design. I decided to make a mini-cyclone dust collector myself. The author and developer of this design is considered to be Bill Pentz from California. Having developed a serious allergy to fine wood dust, he subsequently devoted a lot of time and effort to fighting both the disease itself and its causes.

The dust collector is a device whose main element is an inverted frustum, inserted with the bottom into the dust collection container. A tube for connecting to a vacuum cleaner is inserted into the upper part of the dust collector, and on the side, tangentially, there is a tube for connecting the hose from the tool.

When a vacuum cleaner draws in air inside the device, turbulence is formed, and debris, moving along with the air, is thrown back by centrifugal forces to the inner walls of the filter, where they continue to move. But as the cone narrows, the particles collide more often, slow down and, under the influence of gravity, fall into the lower container. And the partially purified air changes direction and exits through a vertically installed pipe and enters the vacuum cleaner.

There are two mandatory requirements for this design. This is, firstly, its tightness, otherwise there will be a sharp loss of suction power and quality of air purification. And, secondly, the rigidity of the container and the cyclone body itself - otherwise it tends to flatten.

There are tables on the Internet with drawings of cyclones for different particle sizes. You can make the cyclone body yourself from galvanized steel or plastic, or you can select a ready-made container of a similar shape. For example, I have seen cyclones made on the basis of a traffic cone (necessarily hard), plastic flower vase, tin horn, large copier toner tube, etc. It all depends on what size cyclone is needed. The larger the debris particles, the larger the diameter of the tubes for the connected hoses and the more massive the cyclone itself becomes.

Bill Pentz points out some of the features of his design. So, the smaller the diameter of the cyclone, the greater the load on the vacuum cleaner. And if the garbage container is low and flat, then there is a possibility of debris being sucked out of the container and falling into the vacuum cleaner. When using a container of any shape, it should not be filled to the top with debris.

Choice of material. I decided to use plastic pipes as blanks for external sewerage and fittings for them. Of course, it will not be possible to create a full-fledged cone from them, but I was not the first to try to use them for this purpose. The advantage of this choice is the rigidity of the parts and the tightness of their connections due to the seals. Another plus is that there are various rubber pipe inserts that allow you to easily and tightly connect the vacuum cleaner hose. In addition, if necessary, the structure can be easily disassembled.

For your own to collect large sawdust and shavings I made a cyclone from a pipe ∅160 mm. I used ∅50 mm pipes as connectors for the hoses. I would like to draw your attention to the fact that the eccentric adapter from a pipe ∅110 mm to ∅160 mm must be funnel-shaped. I've come across flat ones, but they won't work - nothing will work with them, and the debris will get stuck.

Do-it-yourself cyclone work progress

Operating procedure. In the plug for the ∅160 mm pipe and in the body pipe, I made holes for outlets for hoses. Next, using a heat gun, I glued a piece of ∅50 mm pipe into the plug. It should be located in the middle of the cyclone body and be a couple of centimeters below the side tube, so it is better to first glue a longer pipe into the plug and then cut it in place during assembly.

I found complaints online that the hot melt adhesive does not stick to PVC pipe, and advice to weld parts using a soldering iron and pieces of the pipe itself. I tried, but didn't do it. Firstly, the glue stuck perfectly to me, and secondly, the smell of melted plastic discouraged anyone from welding anything this way, although the connection would probably be stronger and more accurate.

The difficulty of working with hot-melt adhesive is that it does not spread, and if you lack the skills, the seam will not be very smooth. I had one like this bad experience- To straighten the seam, I decided to heat it with a hairdryer. I got a smooth surface of the adhesive bead, but at the same time the plastic tube itself was deformed and had to be thrown away.

On next stage I glued a spiral to the inner surface of the case, which should direct the air flow down to the dust collector. This solution was recommended by Bill Pentz himself - according to him, this almost doubles the efficiency of the cyclone. The spiral with a height of about 20% of the gap should fit tightly to the body and make one turn with a pitch equal to the diameter of the inlet hole for the side pipe.

As a material for it, I used a plastic rod, which I heated with a hairdryer and bent into a spiral shape. (photo 1), and then glued it into the body (photo 2) using a heat gun. Then I glued the side tube (photo 3), the inner end of which is directed slightly downwards.

Once the glue cooled and hardened, I measured and cut the vertical outlet tube so that it was 2-3 cm below the cut of the side tube, and finally assembled the entire structure.

I made a container for garbage from a hard plastic barrel, to the bottom of which I attached wheels - this turned out to be very convenient for cleaning it (photo 4). I cut a viewing window on the side of the barrel and covered it with acrylic glass on hot glue. I reinforced the connection from above with a plastic ring and bolts. Through such a porthole it is convenient to monitor the filling of the container.

I didn’t have a lid for the barrel, so I made it from a piece of countertop that had been waiting in the wings for a long time after installing a sink in the kitchen (photo 5). On the underside of the tabletop, I used a router to select a groove for the edges of the barrel and glued a window seal into it to seal the joint. (photo 6). According to the rules, the hole in the lid should be made in the center, but then I would have problems with placing the cyclone in the workshop, so I made the hole offset. The lid is attached to the barrel using latches from a long-broken vacuum cleaner. I also used a hose from it to connect the cyclone. I would like to draw your attention to the fact that it is better to take hoses from vacuum cleaners. If you take, say, a corrugated pipe for electrical wiring, when you turn on the vacuum cleaner, a whistling and terrible noise appears.

DIY cyclone for vacuum cleaner

Connecting the cyclone to the instrument. Not all tools have an outlet for a vacuum cleaner. So I decided to make a simple, adjustable vacuum cleaner hose holder. For him, I made blanks for levers from scraps of plywood. (photo 7). The holder was supplemented with a sewer clamp for attaching the hose (photo 8). I made the stand specially large sizes so that it is possible to secure it with a clamp or hold it with a weight. The holder turned out to be convenient - I use it not only for the vacuum cleaner hose, but also for a portable lamp, laser level and supporting a long workpiece in a horizontal position.

After assembling the cyclone, I conducted several experiments to determine its efficiency. To do this, I sucked up a glass of fine dust, and then measured its volume that fell into the dust collector container. As a result, I was convinced that approximately 95% of all garbage ends up in the barrel, and only very fine dust, and only a small amount, gets into the vacuum cleaner bag. I am quite happy with this result - now I clean the bag 20 times less often, and only for fine dust, which is much easier. And this despite the fact that my design is far from perfect in shape and proportions, which certainly reduces efficiency.

Wiring. After checking the performance of the cyclone, I decided to make a stationary distribution of hoses throughout the workshop, since a three-meter hose is certainly not enough, and a vacuum cleaner with a cyclone is bulky and clumsy, and it is inconvenient to move them around the workshop every time.

Thanks to the fact that standard pipes were used, it was possible to install such wiring in an hour. I pushed the vacuum cleaner and cyclone into the very far corner, and laid pipes ∅50 mm throughout the workshop (photo 9).

In the workshop I use a specialized BOSCH green series vacuum cleaner. After four months of using it in tandem with the cyclone, I can say that they generally cope with their task. But I would like to slightly increase the suction power (when working with a jigsaw you have to move the hose almost close to the cutting zone) and reduce the noise level. Since little shavings get into the vacuum cleaner itself, there is an idea to make a more powerful impeller and move it outside the workshop to the street.

I can also say that the suction power of the vacuum cleaner dropped a little when using it with a cyclone, but this is not very noticeable at work. There were doubts that static electricity could accumulate on the elements, since the entire structure is plastic, but practically this does not happen, although previously the hose had to be grounded when collecting fine dust.

Of course, when using professional pipelines with large outlet openings, this diameter is not enough. It is better to take ∅110 mm or more, but then both the vacuum cleaner and the cyclone must be more powerful. However, for my homework this is quite enough.

The vacuum cleaner hose was firmly secured to a small branch of the ∅50 mm pipe and inserted into the desired wiring location. The remaining wiring outputs are closed with plugs firmly placed on short bends. Moving the hose is a matter of seconds.

During operation I encountered one small problem. If a small pebble (my concrete floors have not been repaired for a long time) or another small but heavy object gets into the hose, it moves through the pipes to the vertical section in front of the cyclone and remains there. When such particles accumulate, other debris clings to them, and a clog can form. Therefore, in front of the vertical section of the wiring, I embedded a camera made of a ∅110 mm pipe with an inspection window. Now all the heavy debris collects there, and by unscrewing the lid it is easy to get out. This is very convenient when a fastener or small part accidentally gets into the vacuum cleaner. It’s simple here - I unscrew the lid, turn on the vacuum cleaner and mix everything that remains in the revision with my hand. Small particles immediately fly into the cyclone container, while large particles remain and are easily removed. Their quantity is usually insignificant, but recently I found a missing screwdriver bit in such garbage.

Also, the inspection hole can be used to temporarily connect a hose ∅100 mm. Just unscrew the lid and you get a finished hole ∅100 mm. Naturally, in this case it is necessary to mute all other wiring inputs. To simplify connection, you can use a flexible adapter (photo 10).

For remote activation the vacuum cleaner installed a switch next to the hose clamp (photo 11) and additional. It can be used to connect a power tool, then you will definitely not forget to turn on the vacuum cleaner before using the tool - this happens to me often.

I use all of these devices regularly. I'm pleased with the result - there is noticeably less dust in the workshop, making cleaning easier. During this time, I collected several bags of sawdust, and very little debris accumulates in the vacuum cleaner. I want to check the cyclone for collecting small garden waste and dust when cleaning a concrete floor.

I think this design is very useful and affordable to make at home.

About filters.
The cyclone filter does not retain more than 97% of dust. Therefore, additional filters are often added to them. From English “HEPA” is translated as “High Efficiency Particulate Air” - a filter for particles contained in the air.

Agree that even you cannot imagine your life without such necessary equipment like a vacuum cleaner? They cope not only with dust, but also with dirt.

Of course, vacuum cleaners can be used not only at home, but they also come in different types: battery-powered, washing, and pneumatic. As well as automobile, low-voltage industrial, backpack, gasoline, etc.

Operating principle of a cyclone vacuum cleaner

James Dyson is the first creator of the cyclone vacuum cleaner. His first creation was G-Force in 1986.

A little later in the 1990s, he submitted a request to manufacture cyclone devices and had already assembled his own center for the creation of vacuum cleaners. In 1993, his first vacuum cleaner, known as the Dayson DC01, went on sale.
So, how does this cyclone-type miracle work?

It appears that the creator, James Dyson, was a remarkable physicist. Thanks to centrifugal force, it is involved in collecting dust.

The device has two chambers and is divided into two types - external and internal. The air that spins inside the dust collector moves upward, as if in a spiral.

According to the law, large dust particles fall into the outer chamber, and everything else remains in the inner chamber. And the purified air leaves the dust collector through filters. Here's how cyclone filter vacuum cleaners work.

Vacuum cleaners with a cyclone filter, features

Do not opt ​​for those models that require little power. You will definitely not like this kind of cleaning and most likely, you will want to throw away such a device.

Don't waste your money, but take a more serious approach to buying a vacuum cleaner. You just have to contact the sales consultant and he will help you with choosing a particular vacuum cleaner.

You should choose a device that is 20-30% more powerful than a bagged vacuum cleaner. It is best to take the one with a power of 1800 W. Almost all vacuum cleaner manufacturers produce models with this filter, which is good news.

Advantages of cyclone dust collectors

1. This has probably happened to everyone, when an item you accidentally needed ended up in the dust collector? Now this is not a problem because it is transparent! And you will always be able to notice objects that need to be pulled out of there as quickly as possible.

This is one of the most important advantages.

2. The power of such vacuum cleaners is maximum and does not reduce speed and power, even when the container is clogged. Cleaning is much more enjoyable, power does not drop, cleaning is cleaner.

This vacuum cleaner is capable of holding much more than you imagine. Up to 97%!!! Not likely, right? Although some are dissatisfied with this result, as they prefer vacuum cleaners with a water filter.

3. By buying a cyclone vacuum cleaner, you are not only making a good purchase, but also saving space for storing it, since its weight is quite light. You won't have to carry heavy weights.

4. There is no need to constantly change paper bags for the vacuum cleaner.

5. Power. She is not lost from fullness.

6. It can be washed thoroughly with water and dried.

Disadvantages of cyclone dust collectors

1. One of the disadvantages of these vacuum cleaners is not very pleasant. This is washing and cleaning the filter. Of course, you won’t have to clean the container with a brush every day, but still, this is one of the disadvantages. Laziness is present in every person. Yes, of course it’s unpleasant to face the fact that you need to get your hands dirty.

2. Noise. The noise from this type of vacuum cleaner is much greater than from a regular one.

3. Energy consumption. It is also much higher than that of a conventional vacuum cleaner. It's a small tornado.

It's up to you to decide whether to buy this little miracle or not. In fact, all its advantages outweigh its few shortcomings. A clean house is much nicer than a half-finished tidy, wouldn’t you agree?

Personal impressions

Compared to an old vacuum cleaner, the cyclonic dust collector looks quite modest in size. It is impossible to believe that such a little thing is capable of something serious. Now the old vacuum cleaner can only be used for wet cleaning.

When I use it for the first time, I take out the accessories, insert a small diameter pipe, turn on the device, and what’s really surprising is that the brush cleans the carpets much better than my previous assistant.

He cleans everything. Dirt, hair from our pets. Previously, you had to make a lot of effort to cope with such “now little things”.

I have laminated flooring in my hallway and it was just as easy to clean. The fact is that I have another brush in stock, tougher than the previous one for carpets, so I coped with this task so easily. You know, the sound of this vacuum cleaner is not as loud as they wrote about it on the Internet.

I am pleased with this device because it is light and not so loud. I also liked the compartment for storing all the necessary attachments; it is very convenient that it is built into the vacuum cleaner itself.

Once I knew what this little tornado could do, it was time to clean out the container. Thank God, when I started emptying the dust collector, it fell in dense, large clumps.

Since the debris was compacted by the air flow. No clouds of dust were visible, and it did not rise into the air! So I finished my first cleaning with my cyclone vacuum cleaner. I rinsed the container and that was the end of the cleaning!

All vacuum cleaners are designed for one purpose - cleanliness. This applies to all vacuum cleaners.
Industrial and construction vacuum cleaners are usually used on machines or for cleaning any premises. These vacuum cleaners are quite expensive, since the operating principle of the cyclone filter vacuum cleaner must be selected carefully.
You should also know that industrial devices are most often used during repairs and construction. Leave yours workplace needs to be clean.

DIY cyclone, from transparent plastic video

Construction work is carried out after preparing it and cleaning the surface. As you understand, general cleaning cannot be done with a regular vacuum cleaner. In other words, this is fraught with damage to the device.
Even small debris such as sand, oil, dry mixtures, powdered abrasives and wood shavings are designed only for an industrial vacuum cleaner.
If you suddenly go to choose a vacuum cleaner for construction work, then be sure to specify the types of pollution that it will encounter.
Are you planning to use a vacuum cleaner in a repair environment? Then consider the DIY cyclone vacuum cleaner option. There are many examples of how you can make this kind of vacuum cleaner.

DIY cyclone for vacuum cleaner

1. In order to make such a vacuum cleaner yourself, you will need a Ural PN-600 Vacuum Cleaner, a plastic bucket (even suitable for paint), a pipe 20 cm long and 4 cm in diameter.
2. The nameplate is also unscrewed, and the holes need to be sealed.
3. The pipe is quite thick and will not fit into the hole, so you need to grind off the rivets using a grinder and remove the pipe fastenings. Before doing this, remove the springs with clamps. Wrap electrical tape around the plug and insert it onto the plug.
4. At the bottom, make a hole in the middle with a drill. Then expand it to 43 mm with a special tool.
5. To seal it, cut out gaskets with a diameter of 4 mm.
6. Then you need to put everything together, the bucket lid, gasket, centering pipe.
7. Now we need self-tapping screws 10 mm long and 4.2 mm in diameter. You will need 20 self-tapping screws.
8. Cut a hole from the side of the bucket along the suction pipe. The cutout angle should be 10-15 degrees.
9. We try on and edit the shape of the hole using special scissors that cut for metal.
10. Don’t forget that you need to try on the inside too. Also leave strips on the inside for self-tapping screws.
11. Using a marker, mark the hole in the bucket and trim off the excess material with scissors. Attach the pipe to the outside of the bucket.
12. To seal everything you need to use a 30x bandage. From an ordinary first aid kit and glue like “titanium” for foam. Wrap a bandage around the pipe and soak it with glue. Preferably more than once!
13. While the glue is drying, you can check how this vacuum cleaner will work. Turn on the vacuum cleaner and load it, blocking the nozzle with your palm. When checking the operation of the vacuum cleaner, the process of sealing and connection with the pipe is improved. It is unlikely that he will soon become obsolete.
14. It is best to store the vacuum cleaner in a case.

Cyclone-type installations are used in industry for purifying gases and liquids. The operating principle of the filter is based on the physical laws of inertia and gravity. Air (water) is sucked out of the device through the upper part of the filter. A vortex flow is created in the filter. As a result, the contaminated product enters the filter through a pipe located on the side of the upper part. Since debris particles are heavier, they settle in the lower part of the filter, and the purified product is discharged through the upper part. Today we will look at just such a filter, made for the workshop, together with the author of the homemade product.

Tools and materials:
76 l waste container;
Plywood;
Polycarbonate;
Plastic pipe;
coupling;
Fasteners;
Masking tape:
Manual frezer;
Electric jigsaw;
Drill;
Glue gun;
Band saw;
Sander.

Then from the lid, using band saw, cuts out a circle with a diameter of 40 cm.

The place of the cut is glued and polished.

In a circle with a diameter of 40 cm, which remains from cutting out the bottom cover, cut out the middle according to the diameter of the plastic pipe. This blank will be installed at the top of the device.

For the side wall, the author used transparent polycarbonate. This will allow you to control the operation of the filter and the filling of the trash can. I rolled up a polycarbonate cylinder and inserted it into the inner hole of the bottom cover. Marked and cut along the joint. I received a cylinder with a diameter of 40 cm and a height of 15 cm.

Having inserted the polycarbonate cylinder into the inner ring of the bottom cover, drill holes in 10 cm increments. Fix the cylinder with self-tapping screws. In order to crush the polycarbonate, the bottom of the screws must be flat.

The top cover is inserted into another part of the cylinder. Secure with tape. After drilling the holes, fasten the polycarbonate with self-tapping screws.

For the inlet and outlet holes the author used plastic pipe with a diameter of 7.6 cm, as well as two couplings for it.
First, the inlet hole is made. Cuts a 23 cm piece from the pipe. Cuts the coupling in half. Cut a rectangle from plywood with sides 12.5 and 15 cm. Cut a hole 8.9 cm in the middle ( outside diameter couplings). Inserting a pipe into the hole, secure it on both sides with a coupling. Seals the seam with hot glue.

A cut piece measuring 12.5 by 20 cm is screwed to the side wall of the rectangle (12.5 cm).

Then the author cuts the pipe and plywood in such a way that the curvature of the cut coincides with the curvature of the cylinder.

Having attached the structure to the installation site, he takes measurements to make a vertical support. Having cut it out, it is attached to the body. It attaches where the seam of the cylinder goes, thus closing it.

Marks the location of the inlet cutout on the polycarbonate. He cuts it out with a drill.

Installs the inlet pipe into the hole and secures it. The seam is sealed with hot glue.

Next he makes the outlet pipe. Cuts a 15 cm piece of pipe. Inserts it into the hole in the top cover. Installs a coupling on both sides. Treated with hot glue.

The author made the bottom screen from MDF. Screen size 46 cm in diameter, thickness 3 mm. Draw a circle at a distance of 5 cm from the edge. Measures an angle of 120 degrees. Trims a strip between the sides of a corner. Screws the screen to the bottom cover so that the cutout begins immediately behind the inlet pipe.

An example of creating a cyclone filter for a household vacuum cleaner in a workshop from Nikita Supryagin.

I finally finished the cyclonic separator filter for the vacuum cleaner. Since I work with wood, there is always an abundance of sawdust, and household vacuum cleaner when collecting this sawdust it gets clogged at the moment, I decided to build a cyclone. After watching enough videos and articles on the Internet, I settled on.

I reworked it a little, assembled it, tested it, and was pleased with the result. Approximately 95-98% of all debris remains in the filter. Below I am attaching a photo with descriptions.

So, for work we needed: an old traffic cone, 40 mm sewer pipes, at least one 45 degree angle, a piece of plywood, chipboard scraps, Hot glue gun with rods, paint bucket can.

We cut out the top cover that covers the cone from plywood with a jigsaw. In it with a core drill suitable diameter A pair of holes are made - one in the center, and the second eccentric.

We insert the tube into the central one, with the extension upward (the hose from the vacuum cleaner will subsequently be inserted into it). We glue the joint of the tube with hot glue.

A pipe is also glued into the second hole, but we put an angle of 45 degrees on it (which is the swirler) - the flow, escaping at an angle, twists in a spiral. The angle must be inside the cone.

This cover is glued onto the top of the traffic cone, covering the large hole.

The cone is sawn off from below and glued into the lid of the jar. The lid itself was additionally reinforced with chipboard scraps.

These scraps with a hole in the center are pulled together with self-tapping screws.

I hope my experience is useful to someone.

When working in a workshop or at home with a grinding tool, when processing parts and preparing surfaces, the need arises to remove fine dust. And, of course, it is advisable to reduce its concentration even during work by organizing local constant air purification at the workplace.

At enterprises, this problem is solved by installing filter units with a cyclone, which collects and sediments dust with the required efficiency.

In our case it is enough make a vacuum cleaner with a cyclone, thereby saving on purchase construction vacuum cleaner, where such a function is provided by the manufacturer.

The principle of operation of a homemade construction vacuum cleaner with a cyclone filter

There are several options for making a cyclone for domestic needs. To decide on the most effective scheme operation of the equipment, you should know the operating principle of this filter.

Cyclone in classic version It is a cylinder and a cone, in the upper part of which there is an inlet for polluted air and an outlet for purified air.

The inlet is made so that the air enters the filter tangentially, forming a rotating flow directed towards the equipment cone (down).

Inertial forces act on pollutant particles and carry them out of the flow to the walls of the apparatus, where dust settles.

Under the influence of gravity and secondary flow, the mass deposited on the walls moves towards the cone and is removed into the receiving hopper. The purified air rises up along the central axis and is discharged through a pipe located strictly in the center of the upper platform of the cyclone.

Required condition effective cleaning air is the exact calculation of the apparatus and the tightness of the cyclone, including in relation to the receiving hopper.

Otherwise, the principle of operation is disrupted and chaotic air movement occurs, preventing dust from settling normally.

In addition, it is necessary to select a motor that sucks in contaminated air, which will ensure optimal operating parameters of the equipment.

Homemade filter for a construction vacuum cleaner, the variants of which are offered on the Internet cannot be called a full-fledged cyclone.

The most simple circuit Such equipment is a plastic barrel with an embedded inlet pipe tangentially, a built-in filter from a car inside the “cyclone” body, through which purified air is removed and to which a household vacuum cleaner is connected.

The disadvantages of the equipment are the absence of a formed flow swirling along the walls of the barrel and a laminar return flow.

In essence, we get an additional capacity for settling large particles (sawdust, shavings), and fine dust will clog the outlet filter and will require constant cleaning.

To improve the design, we suggest supplementing the plastic barrel with a homemade cyclone made from a traffic cone. It is best if the work is carried out over several hours, install stationary option equipment for removing dust from the workplace.

In this case we need a radial household fan. And with a one-time connection of the cyclone, it is enough to use a regular vacuum cleaner with adjustable suction power.

Sometimes an additional rheostat is installed to reduce the rotation speed of the vacuum cleaner engine, thereby selecting the parameters necessary for the normal functioning of the filter.

In the following sections of the article we will present you with two options for a cyclone for domestic use.

Selection of equipment - what is needed for work

For the first design option for a permanent installation, you will need the following components:

• Plastic barrel;
• Gray plastic sewer pipe with a diameter of 50 mm;
• Traffic cone;
• Corrugated hoses, reinforced with steel wire or metallized hoses;
• Adhesive for plastic;
• Radial household fan with the ability to change the engine speed and performance equal to six times the exchange of air in the room;
• Plywood 10-12 mm thick.

The second version of the product is the most successful, since in this case the product approaches the functionality of a real cyclone.

To make a filter you will need to purchase:

• Ready-made plastic cyclone made in China;
• A barrel, bucket or other container for making a dust bin;
• Corrugated hoses.

A plastic cyclone is inexpensive, approximately 1500-2500 rubles, and is designed to collect medium and heavy dust. Works great with shavings and sawdust.

Step-by-step instructions for the cyclone assembly process

Our first option is stationary design for workshops with large amounts of dust of various origins.

Assembling a cyclone filter for a vacuum cleaner

1. First we make the cyclone itself. We make a hole in the plastic cone for passage sewer pipe on a tangent.
2. For better connection The mating surface of the pipe with the cone body is matted with emery cloth. We glue the seams using a mounting gun.
3. In the upper part of the cone we install a vertical pipe, the lower end of which should be below the inlet. In this way we can achieve vortex air movement. The pipe is fixed in a plywood sheet in the shape of a circle with a diameter equal to the size of the base of the cone.
4. The prepared cyclone is secured to the barrel lid using a round plywood sheet.
5. To prevent the plastic barrel from becoming deformed under the influence of vacuum when the inlet pipe becomes clogged with debris, we install a spacer inside the container - a frame made of plywood sheet. The external dimensions of the frame are the same inner diameter barrels. To strengthen the structure, we attach the construction cone to the lid of the container using metal pins.
6. Next, we connect the cyclone to the corrugated hoses at the inlet and outlet. We install a radial household fan outdoors under a canopy.

The second version of the construction vacuum cleaner is based on a Chinese plastic cyclone, which is also attached to any of the selected containers. The result is a reliable and efficient design.
The cyclone is attached to the container using a metal clamping flange.

VIDEO INSTRUCTION

When starting the vacuum cleaner and further operation, do not forget to clean the inlet pipe and stop the internal spacers on the containers to prevent deformation of the receiving hopper.

If finer air purification is required, the design is supplemented with a car filter in the housing at the outlet of the product.
