[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the present invention, a filter is provided in combination with a cleaning brush. When the induced draft fan drives the exhaust gas to the air inlet pipe, the exhaust gas is filtered by the filter before entering the pickling tower. At the same time, due to the action of the induced draft fan, the wind force brought by the exhaust gas drives the turntable to drive the rotating shaft to rotate. At this time, the rotating shaft drives the cleaning brush to rotate. The cleaning brush moves the dust on the surface of the filter during the rotation. At this time, the dust is loosened and leaves the surface of the filter, reducing the probability of clogging of the filter and preventing it from affecting the circulation of the exhaust gas. When the wind is weak, the dust falls downward into the interior of the collection box. After the work is completed, the rotary cover is rotated to release the connection between the rotary cover and the external thread. At this time, the dust accumulated inside the collection box flows downward, and the staff can collect the dust to prevent a small amount of aluminum ash from entering the pickling tower with the induced draft fan and mixing with the reagent to affect the ammonia treatment efficiency.

[0016] In the present invention, a threaded rod is provided to cooperate with the mounting groove, and the threaded cap is rotated to release the connection between the threaded cap and the threaded rod. At this time, the fixing plate is pulled to drive the mounting bracket to be taken out from the inside of the mounting groove. At this time, the mounting bracket is disassembled. During installation, the mounting bracket is inserted into the inside of the mounting groove, and then the threaded cap is threadedly connected to the outside of the threaded rod until the threaded cap is tightly fitted with the surface of the fixing plate. At this time, the mounting bracket is installed. The disassembly and assembly process of the mounting bracket is simple, which is convenient for the staff to replace the mounting bracket and improves the work efficiency of the staff.

[0017] In the present invention, a fixing plate is provided to cooperate with the plug plate. When the mounting frame is disassembled, the fixing plate is pulled to release the connection between the fixing plate and the slide groove and the opening. At this time, the plug plate and the rotating shaft can be pushed to release the connection between the plug plate and the slide groove and the rotating shaft and the opening. At this time, the connection between the cleaning brush and the two turntables and the rotating shaft are all released. At this time, the cleaning brush and the two turntables fall from the inside of the mounting hole. At this time, pushing the filter screen can release the connection between the filter screen and the mounting hole. At this time, the filter screen and other structures can be cleaned, which is convenient for the staff to clean each structure one by one, thereby improving the cleaning quality. At the same time, the disassembly and assembly process of each structure in the filter mechanism is simple, which is convenient for the staff to quickly replace the damaged structure.

[0018] In the present invention, a scraper is provided in conjunction with a collection box. As the cleaning brush continuously cleans the filter screen, dust gradually accumulates on the surface of the cleaning brush. When the cleaning brush rotates to the scraper, the protrusions on the outside of the scraper come into contact with the bristles of the cleaning brush, thereby loosening the impurities attached to the surface of the bristles. As the impurities are loosened and the cleaning brush rotates, the impurities are thrown out by the cleaning brush, reducing the impurities attached to the surface of the cleaning brush and improving the cleaning effect of the cleaning brush.

[0019] In the present invention, a handle is provided to cooperate with the placement slot. When the connection between the mounting bracket and the mounting slot is released, if the connection between the fixing plate and the mounting bracket is released during the process of pulling the fixing plate, the handle can be rotated out of the placement slot. At this time, the handle can be pulled to drive the mounting bracket to release the connection between the mounting bracket and the mounting slot, thereby reducing the inconvenience caused by the disassembly process of the mounting bracket and improving the work efficiency of the staff.

[0033] The lower end of the air inlet pipe 2 is fixedly connected to a collection box 12, which is located at one end of the filter 8 close to the cleaning brush 10. The bottom of the collection box 12 is provided with an external thread 13, and the external thread 13 is connected to a rotary cover 14.

[0034] By providing a filter 8 and cooperating with a cleaning brush 10, when the induced draft fan 4 drives the exhaust gas to the air inlet pipe 2, the exhaust gas is filtered by the filter 8 before entering the pickling tower 1. At the same time, due to the action of the induced draft fan 4, the wind force brought by the exhaust gas drives the turntable 11 to drive the rotating shaft 9 to rotate. At this time, the rotating shaft 9 drives the cleaning brush 10 to rotate. The cleaning brush 10 pokes the dust on the surface of the filter 8 during the rotation process. At this time, the dust is loosened and leaves the surface of the filter 8, reducing the probability of clogging of the filter 8 and preventing it from affecting the circulation of the exhaust gas. When the wind is small, the dust falls downward into the interior of the collection box 12. After the work is completed, the rotary cover 14 is rotated to release the connection between the rotary cover 14 and the external thread 13. At this time, the dust accumulated inside the collection box 12 flows downward, and the staff can collect the dust to prevent a small amount of aluminum ash from entering the pickling tower 1 with the induced draft fan 4 and mixing with the reagent to affect the ammonia treatment efficiency.

When the cleaning brush 10 rotates to the scraper 15, the protrusions on the outside of the scraper 15 come into contact with the bristles of the cleaning brush 10 to loosen the impurities attached to the surface of the bristles. As the impurities are loosened and the cleaning brush 10 rotates, the impurities are thrown out by the cleaning brush 10, reducing the impurities attached to the surface of the cleaning brush 10 and improving the cleaning effect of the cleaning brush 10.

[0045] The limiting plate 23 and the limiting block 25 are both slidably connected to the interior of the limiting groove 24 , so as to limit the rotation of the cleaning brush 10 and the turntable 11 .

[0046] By providing a fixing plate 26 and cooperating with the insert plate 18, when the mounting bracket 6 is disassembled, the fixing plate 26 is pulled to release the connection between the fixing plate 26 and the slide groove 17 and the opening 19. At this time, the insert plate 18 and the rotating shaft 9 can be pushed to release the connection between the insert plate 18 and the slide groove 17 and the rotating shaft 9 and the opening 19. At this time, the cleaning brush 10 and the two turntables 11 are all released from the rotating shaft 9. At this time, the cleaning brush 10 and the two turntables 11 fall from the inside of the mounting hole 7. At this time, pushing the filter screen 8 can release the connection between the filter screen 8 and the mounting hole 7. At this time, the filter screen 8 and other structures can be cleaned, which is convenient for the staff to clean each structure one by one and improve the cleaning quality. At the same time, the disassembly and assembly process of each structure in the filter mechanism is simple, which is convenient for the staff to quickly replace the damaged structure.

[0047] A fixing plate 26 is provided on the outside of the air inlet pipe 2, and one end of the fixing plate 26 is clamped in the two chute 17 and the inside of the opening 19;

The two threaded caps 30 are attached to the end of the fixing plate 26 away from the slide groove 17 to facilitate fixing the mounting frame 6.

[0049] By providing a threaded rod 27 and cooperating with the mounting groove 5, the threaded cap 30 is rotated to release the connection between the threaded cap 30 and the threaded rod 27. At this time, the fixing plate 26 is pulled to drive the mounting frame 6 to be taken out from the inside of the mounting groove 5. At this time, the mounting frame 6 is disassembled. When installing, the mounting frame 6 is inserted into the inside of the mounting groove 5, and then the threaded cap 30 is threadedly connected to the outside of the threaded rod 27 until the threaded cap 30 is tightly fitted with the surface of the fixing plate 26. At this time, the mounting frame 6 is installed. The disassembly and assembly process of the mounting frame 6 is simple, which is convenient for the staff to replace the mounting frame 6 and improves the work efficiency of the staff.

[0050] A handle 31 is provided on one side of the mounting frame 6 close to the fixing plate 26;

[0051] A placement slot 32 is provided on the outside of the mounting bracket 6 , and a connecting shaft 33 is rotatably connected to the inside of the placement slot 32 . The handle 31 is fixedly connected to the outside of the connecting shaft 33 to facilitate pulling the mounting bracket 6 .

[0052] By providing the handle 31 and cooperating with the placement groove 32, when the connection between the mounting bracket 6 and the mounting groove 5 is released, if the connection between the fixing plate 26 and the mounting bracket 6 is released during the process of pulling the fixing plate 26, the handle 31 can be rotated out of the placement groove 32. At this time, the handle 31 can be pulled to drive the mounting bracket 6 to release the connection between the mounting bracket 6 and the mounting groove 5, thereby reducing the inconvenience caused by the disassembly process of the mounting bracket 6 and improving the work efficiency of the staff.

[0053] A sealing gasket 28 is provided on one side of the fixing plate 26 close to the mounting frame 6;

[0054] An annular groove 29 is formed on the outside of the fixing plate 26 , and a sealing gasket 28 is clamped inside the annular groove 29 to enhance sealing performance.

[0055] A baffle 3 is fixedly installed inside the collection box 12;

[0056] The baffle 3 is located at one end of the collecting box 12 away from the rotary cover 14 , thereby reducing the probability of impurities accumulated inside the collecting box 12 floating up.

[0057] Working principle:

[0058] 8, and the filter screen 8 is fixed in the inner part of the mounting hole 7. At this time, the shaft 9 is inserted into the inner part of the mounting hole 7 through the opening 19. At this time, a turntable 11 is placed on the end of the mounting hole 7 close to the opening 19 and the concave part of the turntable 11 is aligned with the filter screen 8, while the turntable 11 body faces downward. At this time, the shaft 9 is pushed and the shaft 9 is entered into the inner side of the fixing ring 22. At this time, the limiting block 25 enters the inner part of the limiting groove 24. At this time, the cleaning brush 10 is placed in the inner part of the mounting hole 7. At this time, the shaft 9 can be continued to be pushed and the shaft 9 is entered into the inner part of the fixing hole 21. At this time, the limiting plate 23 enters the inner part of the limiting groove 24. At this time, another turntable 11 is installed according to the above order. The concave part of this turntable 11 is not aligned with the filter screen 8 and the turntable 11 body faces upward. At this time, the filtering mechanism is completed.

[0059] In the second step, insert the mounting bracket 6 into the mounting groove 5. During the insertion process, the bristles of the cleaning brush 10 are made of soft material. Therefore, during the insertion of the mounting bracket 6 into the mounting groove 5, the bristles of the cleaning brush 10 are compressed by the inner wall of the mounting groove 5 to the inside of the mounting hole 7 until the mounting bracket 6 is restored to its original state and contacts with the scraper 15 after the installation is completed. At this time, one end of the fixing plate 26 is clamped in the two slide grooves 17 and the inside of the opening 19, and the threaded cap 30 is threadedly connected to the outside of the two threaded rods 27 to fix the fixing plate 26 to the outside of the air inlet pipe 2. At this time, the sealing gasket 28 is completely fitted with the outside of the air inlet pipe 2, filling the small gap between the fixing plate 26 and the outside of the air inlet pipe 2 to increase the sealing. At this time, the installation of the mounting bracket 6 is completed.

[0060] In the third step, by providing a filter screen 8 and cooperating with a cleaning brush 10, when the induced draft fan 4 drives the exhaust gas to the air inlet pipe 2, the exhaust gas is filtered by the filter screen 8 before entering the pickling tower 1. At the same time, due to the action of the induced draft fan 4, the wind force brought by the exhaust gas drives the turntable 11 to drive the rotating shaft 9 to rotate. At this time, the rotating shaft 9 drives the cleaning brush 10 to rotate. The cleaning brush 10 pokes the dust on the surface of the filter screen 8 during the rotation process. At this time, the dust is loosened and leaves the surface of the filter screen 8, reducing the probability of clogging of the filter screen 8 and preventing it from affecting the circulation of the exhaust gas. When the cleaning brush 10 rotates to the scraper 15, the scraper The protrusions on the outside of the plate 15 come into contact with the bristles of the cleaning brush 10 to loosen the impurities attached to the surface of the bristles. As the impurities are loosened and the cleaning brush 10 rotates, the impurities are thrown out by the cleaning brush 10. When the wind is weak, the dust falls downward into the interior of the collection box 12. After the work is completed, the rotary cover 14 is rotated to release the connection between the rotary cover 14 and the external thread 13. At this time, the dust accumulated in the collection box 12 flows downward, and the staff can collect the dust to prevent a small amount of aluminum ash from entering the pickling tower 1 with the induced draft fan 4 and mixing with the reagents to affect the ammonia treatment efficiency.
