Description

Timing Belt Drive Automatic Cleaning Air Filter

The present invention relates to an automatic cleaning air filter for enclosing foreign substances such as dust and harmful gases from air or gas, and more particularly, a plurality of cleaning liquids capable of spraying the cleaning liquid over the entire length of the demister filter. The present invention relates to a timing belt driving automatic cleaning air filter in which a nozzle is installed in a reciprocating slider reciprocating from side to side and the reciprocating slider is moved left and right by a timing belt to move the reciprocating slider side to side without loosening for a long time. .

In general, the air cleaning air filter is air blown to pass through the automatic cleaning air filter device is installed in the frame 24, a plurality of demister filter 26 is fixed in a mat form, as shown in Figs. Injector 10 having a cleaning liquid injection nozzle 10 'XY reciprocating from the front of the automatic cleaning air filter to the left and right, up and down in front of the automatic cleaning air filter to collect the foreign matter mixed with the gas on the mat and to remove the collected foreign matter. This constitutes a cleaning device.

The conventional reciprocating XY movement mechanism of the cleaning device is a chain drive system, and the chain sprocket 16 and the chain 14 therebetween which are installed above and below the side frame 22 as shown in Figs. By the injection pipe 10 is reciprocated from side to side. In this way, the plurality of cleaning liquid injection nozzles 10 'formed over the entire width of the upper and lower sides are configured to be reciprocated left and right, thereby performing the washing operation over the entire surface of the plurality of demister filter 26 mats.

In the above-described chain drive method, a support member is formed to extend one connection pin of the chain to protrude and the protruding connection pin is inserted to reciprocate the injection pipe 10 at least up and down as the chain moves and rotates. There is a problem that, due to the sliding movement between the slot and the connecting pin of the chain is a lot of breakage or wear occurs, and also the load (tension) on one side of the chain is caught a lot, such that the chain is easily sag. In particular, the support member along with the chain 14 passes through the sprocket 16 at both ends, so that the chain 14 or the sprocket 16 is directly exposed to the foreign matter and water, so that the foreign matter and water adhere to each other. In addition, since the material is steel, it requires frequent replacement or repair due to problems such as corrosion during water spraying. It takes significantly easier.

In addition, since a proper traction is applied to both sides of the chain 14 to smoothly reciprocate the support member, a sprocket must be installed in the middle, thereby further complicating the structure, and the chain 14 and the sprocket 16 Due to the heavy weight of the back, not only a considerable strength is required for the support structure or the frame, but also the number of the nozzles 10 'is limited because the XY reciprocating portion should be made as light as possible.

The direction of the motor 18 is changed by an electrical control method such as a timer, not by the above-described reciprocating structure by the connecting pin and the slot, thereby rotating the chain 12 in a reciprocating manner or using a ratchet gear in a reciprocating manner. Even when the chain 12 is rotated, the weight of the entire moving part is heavy, and in the latter case, the structure is more complicated, and there is still a lot of load on the chae 12, and frequent repair work is complicated and complicated. . In addition, the angle B-shaped material is used as the guide rail 12, and the support member, which is a reciprocating slider of the injection pipe 10, is mainly used by bending and assembling galvanized steel sheet. And when guided by a steel roller, there is no stability in movement and takes a lot of load, and since the material is steel, water penetrates and corrosion occurs.

The present invention is to solve the above-mentioned problems, to provide a timing belt drive automatic cleaning air filter almost no repair, which can make the moving part lightweight and simplify the structure and at the same time semi-permanently ensure the smooth movement of the reciprocating slider. Its purpose is to.

In order to achieve the above object, the cleaning apparatus for a timing belt driving automatic cleaning air filter according to an embodiment of the present invention is configured to spray cleaning liquids over the entire length of the top and bottom of the plurality of demister filters, and collect the foreign matter collected in the demister filter. At least one spray pipe having a plurality of cleaning liquid spray nozzles for removing the fluid and connected to the flexible cleaning liquid supply hose; A reciprocating slider (30) installed to be movable from side to side to fix the injection tube and to move the left and right full lengths of the plurality of demister filters; A timing belt 46 fixed to the reciprocating slider to move the reciprocating slider from side to side; A horizontal guide rail 32 for guiding the horizontal movement of the timing belt and the reciprocating slider; A pair of fixed fastenings for supporting the left and right moving guide rails fixedly to the automatic cleaning air filter main body at both ends thereof, and rotatably supported at least one of the timing belt pulleys for engaging the timing belts and moving the timing belts left and right. And a support member; And a motor 40 mounted on any one of the fixing and supporting members and connected to the pulley to change the rotational direction of the motor when the reciprocating slider 30 moves to the left and right ends. And a drive means including a pair of switching means respectively installed on the pair of fixed and support members and electrically connected to the power supply portion of the motor.

As such, by driving the reciprocating slider by the timing belt, the force is transmitted to the reciprocating slider over a larger area than the connecting pin of the chain, so that the load per unit width is less, and thus the number of nozzles attached to the reciprocating slider can be increased. The structure can be simplified and lightened by eliminating any movement of up and down and left and right movements.The material structure of the timing belt is made of industrial resin with iron core, so it can be lubricated with almost no lubricant. This is done smoothly.

Hereinafter, an embodiment of the present invention with reference to the accompanying drawings, as follows.

3 and 4 illustrate a timing belt driving automatic cleaning air filter according to an embodiment of the present invention. 3 and 4, the cleaning device of the automatic cleaning air filter has a plurality of cleaning liquid injection nozzles 30 'to reciprocate left and right in front of the automatic cleaning air filter having a plurality of demister filters 26 as in the related art. The reciprocating slider 30 to which the injection pipe 34 is fixed is installed.

A plurality of cleaning liquid injection nozzles 30 'are formed in the injection pipe 34 so as to spray the cleaning liquid over the entire length of the plurality of demister filters 26 to remove foreign substances collected in the demister filter. A flexible cleaning liquid supply hose 38 is connected to the injection pipe 34.

The reciprocating slider 30 fixes the injection pipe 34 to move the left and right guide rails 32 to move left and right so that the cleaning liquid is injected by the injection nozzle 30 'over the left and right full lengths of the plurality of demister filters. Guided by). The left and right moving guide rails 32 are fixed to the side frame 22 by a pair of fixing and supporting members 44 at both ends thereof. The spray nozzle 30 'is formed to spray the cleaning liquid toward the shingles filter 26' of the demister filter 26, as shown in FIG.

The timing belt 46 is guided by the horizontal guide rail 32 while the timing belt 46 is fixed to the reciprocating slider 30 to reciprocate the reciprocating slider 30 from side to side. Rotate around in both directions.

The geared motor 40 is fixedly supported by any one of the pair of fixing and supporting members 44, and is configured to engage the timing belt 46 so that the timing belt 46 is rotated by the rotation of the geared motor 40. ) Rotates in both directions, moving left and right around the guide rail 32.

The pair of fixing and supporting members 44 are fixed to the side frame 22 to firmly support the geared motor 40 and the left and right moving guide rails 32, the timing belt 46, and the reciprocating slider 30. And it firmly supports so that the left and right movement of the injection pipe 34 operates stably.

In addition, a limit switch 36 as switching means is provided on each of the pair of fixed and support members 44 so as to change the rotational direction of the geared motor 40 when the reciprocating slider 30 moves to the left and right ends. The limit switch 36 is electrically connected to the power supply of the geared motor 40.

The geared motor 40 may be fixed to the shaft of the motor when a conventional motor is used and to rotate the timing belt 46 to engage the pulley.

On the other hand, although not shown in detail in the structure, the reciprocating slider 30 is formed by fixing with a square frame made of aluminum extrusion material, the left and right moving guide rail 32, the polishing rod heat-treated on the square aluminum extrusion material It is preferable that the reciprocating slider 30 is guided by the bearing unit on the horizontal guide rail 32 by the bearing unit to improve its lubricity, lightness and durability.

Effects and effects of the configuration of the timing belt driving automatic cleaning air filter according to the embodiment of the present invention described above are as follows.

First, after collecting the foreign matter entrained in the air or gas from the air or gas passing through the automatic cleaning air filter in which the plurality of demister filters 26 are fixedly installed in the form of a mat on the frame 24. In order to stop the operation of the main body and remove the collected foreign matter, the cleaning device installed in front of the automatic cleaning air filter main body 20 is operated.

That is, the geared motor 40 is driven to move the reciprocating slider 30 to one end side of the left and right movement guide rails 32 via the timing belt 46, and the illustration is omitted through the cleaning liquid supply hose 38. When the cleaning liquid is supplied to the injection pipe 34 by the pump, the foreign matter collected by the demister filter 26 is washed by the spraying cleaning liquid.

Of course, the cleaning liquid can be filtered through a suitable filter to allow foreign substances to be discharged and purified for reuse of the cleaning liquid.

When the reciprocating slider 30 reaches one end of the horizontal guide rail 32, the limit switch 36 installed at one end thereof is operated to reverse the geared motor 40 through a power supply (not shown). By rotating, the reciprocating slider 30 moves to the other end side of the horizontally moving guide rail 32. Thus, the cleaning liquid is injected from the plurality of injection nozzles 30 'attached to the injection pipe 34 by switching the polarity of the geared motor 40 by the limit switch 36 installed at the other end as well. As the reciprocating slider 30 is reciprocated from side to side on the left and right moving guide rail 32, a cleaning action occurs over the entire area of the demister filter 26 of the automatic cleaning air filter.

When the cleaning operation is completed as described above, the automatic cleaning air filter is operated again to collect the dust. As described above, the dust collecting operation and the washing operation can be separated, or the dust can be washed while being collected. Further, the use of the timing belt makes it possible to narrow the width of the cleaning device. At the same time, the dust collection efficiency does not decrease even when dust collection and cleaning operations are performed.

In the cleaning operation as described above, since the timing belt 46 is installed in the reciprocating slider 30, the chain is reciprocated by a thin connecting pin, so that a large load is applied and fixed to the reciprocating slider 30. The number of injection pipes 34 and injection nozzles 30 'is limited, but according to the present invention, since the load acts over the entire width of the timing belt 46, many loads can be tolerated. Since it is possible to change the material of many parts from steel to aluminum, and the device can be made much lighter by simplifying the device, the load on the left and right guide rails 32 can be considerably reduced, and the appropriate tension adjustment as in the chain This further necessitates a much smoother reciprocating movement. Accordingly, the injection pipe 34 and the powder are spread over the entire length of the demister filter 26. Even if the nozzle (30 ') is installed, it is possible to move smoothly left and right to remove the reciprocating movement up and down. In addition, unlike the chain, there is an advantage that the timing belt 46 of the industrial resin in which the iron core is embedded can be used semipermanently without the need for oiling.

In particular, since the above-mentioned reciprocating slider 30 is constituted by a square frame made of aluminum extrusion material, the bearing unit is configured, and thus the assembly is easy. Further, the left and right moving guide rails 32 are provided with a polishing rod heat-treated on the square aluminum extrusion material. By configuring to use as a sliding shaft, the friction coefficient between the reciprocating slider 30 and the left and right guiding rails 32 is small and there is little shaking, and the load on the timing belt 46 is further reduced. The operation is smooth.

As described above, the automatic cleaning air filter according to an embodiment of the present invention is made smoothly and precisely by the timing belt 46, and the structure thereof is simple, and the structure is simple. It can be used semi-permanently because oiling and repairing are almost unnecessary, and even when repairing diarrhea, the structure is simple and easy to assemble and disassemble, and it is strong and light, and the appearance is beautiful.
