Description

Timing Belt Driven Electrostatic Precipitator

The present invention relates to an electrostatic precipitator that collects foreign substances such as dust and harmful gases by charging from air or gas, and more particularly, a plurality of nozzles capable of injecting a cleaning liquid over the entire length of the electrostatic precipitating cell. The present invention relates to a timing belt driving electrostatic precipitator having a structure in which a reciprocating slider is installed on 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 electrostatic precipitator is air blown to pass through the electrostatic precipitator installed in the frame 24, a plurality of electrostatic precipitating cells 26 are fixed in a mat form, as shown in Figures 1 and 2 The foreign matter mixed in the gas is charged by electricity (by corona discharge) to collect on the counter dust collecting electrode plate by electrical attraction, and to the front and back of the electrostatic precipitator to remove the collected foreign matter, the XY reciprocating movement A cleaning device having a cleaning liquid jet nozzle 10 'is provided.

The conventional reciprocating XY movement mechanism of the cleaning device is mostly a chain drive system, and as shown in FIGS. 1 and 2, the left and right guide rails on both left and right sides are movable so that the left and right guide rails 12 can reciprocate up and down. It is supported and guided by 22, and the reciprocating slider 10 is supported and guided to the left and right movement guide rails 21 so as to reciprocate from side to side. In this way, the cleaning liquid injection nozzle 10 'is configured to be reciprocated up, down, left and right to perform a cleaning action over the entire surface of the plurality of electrostatic precipitating cells 26.

In the above-described chain drive method, a slot for extending the connecting pin of the chain to protrude and the protruding connecting pin is inserted to reciprocate the reciprocating slider 10 according to the movement and rotation of the chain is provided in the reciprocating slider 10. It is provided, due to the sliding motion between the slot and the connecting pin of the chain is caused a lot of breakage or wear, and also there is a problem such that the chain is easily hung due to a large load (tension) on one side chain, In particular, the reciprocating slider 10 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, thereby adhering the foreign matter and water to smooth lubrication. This does not happen and the material is a steel material, so it requires frequent replacement or repair due to problems such as corrosion during water spraying. The dragon takes a great deal.

In addition, since the reciprocating movement of the smooth reciprocating slider 10 is performed only when an appropriate tension is applied to both sides of the chain 14, the sprocket 16 must be installed in the middle, and thus the structure is more complicated, and the chain 14 Due to the heavy weight of the sprocket 16 and the like, the support structure or the frame has a considerable strength, and the number of 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 the chain 12 is still heavily loaded, and the repair work is often complicated and complicated. . In addition, the angle b-shaped angle steel is used as the horizontal guide rail 12, the reciprocating slider 10 is mainly used to bend and assemble the galvanized steel sheet, the reciprocating slider (10) or the horizontal guide rail ( If the shanghai-dong of 12) is guided by steel rollers, there is no stability in the movement and the load takes a lot, 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 electrostatic precipitator which almost does not require repair, which can lighten the moving parts, simplify the structure and ensure the smooth reciprocation of the reciprocating slider semi-permanently. Its purpose is to.

In order to achieve the above object, the cleaning apparatus of a timing belt driving electrostatic precipitator according to an embodiment of the present invention is configured to spray a cleaning liquid over the entire length of the plurality of electrostatic precipitating cells to collect foreign substances collected in the electrostatic precipitating cell. At least one spray tube having a plurality of cleaning liquid spray nozzles for removal and connected to the flexible cleaning liquid supply hose; A reciprocating slider (30) installed to be movable from side to side to fix the spray pipe and to move the left and right full lengths of the plurality of electrostatic precipitating cells; 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 fixings to which the left and right movement guide rails are fixed to both sides of the electrostatic precipitator main body, and to which the timing belt pulley for engaging the timing belt and moving the timing belt left and right is rotatably supported on at least one thereof; 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 between 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 without lubricating oil. This is done smoothly.

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

A timing belt drive electrostatic precipitator according to an embodiment of the present invention is shown in FIGS. 3 and 4. 3 and 4, the cleaning device of the electrostatic precipitator has a plurality of cleaning liquid injection nozzles 30 'to reciprocate left and right in front of the electrostatic precipitator having a plurality of electrostatic precipitating cells 26 as in the prior 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 to spray the cleaning liquid over the entire lengths of the plurality of electrostatic precipitating cells 26 to remove foreign matters collected in the electrostatic precipitating cells. 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 so as 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 electrostatic precipitating cells. 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 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 left and right around the guide rails 32 or rotates in both directions.

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 a 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 have a pulley fixed to the shaft of the motor when the conventional motor is used, and rotate the meshed belt 46 to 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 extruded 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 electrostatic precipitator according to the embodiment of the present invention described above are as follows.

First, the foreign matter mixed in the air or gas from the air or gas passing through the electrostatic precipitator in which the plurality of electrostatic precipitating cells 26 are fixedly installed in a mat form on the frame 24 is electrically charged (corona). After the dust is collected on the counter dust collecting electrode plate by electrical attraction, and the cleaning device installed in front of the electrostatic precipitator main body 20 is operated to stop the operation of the main body and to remove the collected foreign matter. .

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, foreign matter collected in the electrostatic precipitating cell 26 is detailed by the cleaning liquid to be injected. Of course, the cleaning liquid can be filtered through a suitable filter to release the foreign matter and circulate for reuse of the cleaning liquid.

When the reciprocating slider 30 reaches one end of the left and right moving guide rail 32, the limit switch 36 installed at one end thereof is operated to reverse the geared motor 40 via a power supply unit (not shown). By rotating the reciprocating slider 30 to the other end side of the left and right movement guide rail 32 is moved. 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 reciprocates from side to side on the left and right moving guide rails 32, a cleaning action occurs over the entire area of the electrostatic precipitating cell 26 of the electrostatic precipitator.

When the cleaning operation is completed as described above, the electrostatic precipitator is again operated to perform the dust collection operation.

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 becomes even more unnecessary, resulting in a much smoother reciprocating movement. Accordingly, even when the injection pipe 34 and the injection nozzle 30 'are installed over the entire length of the electrostatic precipitating cell 26, smooth left and right movement can be performed, thereby eliminating reciprocating movement up and down. In addition, unlike the chain, there is also an advantage that it can be used semi-permanently without the need for oiling to the timing belt 46 of the industrial resin with the iron core embedded.

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 be used as a sliding shaft, the friction coefficient between the reciprocating slider 30 and the left and right moving guide rails 32 is small and there is little shaking, and the load on the timing belt 46 is further reduced. This will be smooth.

As described above, the electrostatic precipitator according to the exemplary embodiment of the present invention uses the timing belt 46 to operate the cleaning device part smoothly and precisely, and also the structure is simple. It can be used semi-permanently as it is almost unnecessary to repair and repair, and it is easy to assemble and dismantle even when repairing diarrhea, it is strong and light, and the appearance is also beautiful.
