[0024] It should be pointed out that unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0025] In the present utility model, unless otherwise stated, the orientations such as "upper, lower" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left, right" are usually in the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contours of each component itself, but the above orientation terms are not used to limit the present utility model.

[0026] Please refer to Figures 1-5, A pollutant treatment device for air pollution control, including a treatment tank 1. A suction fan 2 is fixedly installed at the upper end of the treatment tank 1. A suction pipe 3 and an exhaust pipe 4 are fixedly installed on the suction fan 2. One end of the suction pipe 3 is fixedly connected to the treatment tank 1. An air inlet pipe 5 is fixedly installed on one side of the treatment tank 1. A support plate 6 is fixedly installed inside the treatment tank 1. Two limiting rods 7 are fixedly installed at the lower end of the support plate 6. A knocking frame 8 is movably connected to both of the two limiting rods 7. A plurality of knocking blocks 9 are fixedly installed at the lower end of the knocking frame 8. The lower end of each limiting rod 7 passes through the knocking frame 8 and is fixedly connected to a limiting plate 10. A spring 11 is movably sleeved on the outer side of each limiting rod 7. A motor 12 is fixedly installed on one side of the treatment tank 1. The driving end of the motor 12 extends into the treatment tank 1 and is fixedly connected to a convex column 13 which is rotatably connected to the treatment tank 1;

[0027] An installation frame 14 is installed inside the treatment tank 1. A filter screen 15 is fixedly installed on the installation frame 14. An installation groove 16 which is matched with the installation frame 14 is arranged on the treatment tank 1.

[0028] In this embodiment, when the entire treatment device is in use, the suction fan 2 is started. The suction fan 2 drives the air inside the treatment tank 1 to flow, so that the polluted air enters the treatment tank 1 from the air inlet pipe 5 and is discharged from the suction pipe 3 and the exhaust pipe 4 after being filtered by the filter screen 15. Pollutant particles such as dust intercepted by the filter screen 15 will move downward under the action of gravity. During use, when it is necessary to clean the filter screen 15, the motor 12 is started. The motor 12 drives the convex column 13 to rotate. When the protruding part of the convex column 13 rotates to contact the knocking frame 8, the knocking frame 8 will be pushed downward as the convex column 13 rotates, so that the knocking frame 8 drives a plurality of knocking blocks 9 to move downward to knock the filter screen 15. The limiting plate 10 limits it, and the spring 11 is compressed. When the convex column 13 rotates to separate from the knocking frame 8, under the push of the spring 11, the knocking frame 8 moves back to its original position along the two limiting rods 7. By repeating such operations, the knocking blocks 9 continuously knock the filter screen 15, causing the filter screen 15 to vibrate, thereby knocking off the adhered dust and other pollutant particles.

[0029] More specifically, during the long-term use of the entire treatment, the motor 12 can be started to make a plurality of knocking blocks 9 knock the filter screen 15 to vibrate and clean it. When it is necessary to disassemble the filter screen 15 for cleaning or replacement, the installation frame 14 can be driven to move the filter screen 15 out of the installation groove 16.

[0030] Please refer to Figures 1-5, as an implementation method for disassembling the filter screen 15: A positioning rod 17 and a screw rod 18 are fixedly arranged in the installation groove 16. The screw rod 18 is threadedly connected with a sleeve 19. The sleeve 19 is rotatably connected with the installation frame 14. One end of the sleeve 19 passes through the installation frame 14 and is fixedly connected with a turning handle 20. A positioning hole 21 matching the positioning rod 17 is arranged on the installation frame 14.

[0031] Specifically, rotate the turning handle 20. The turning handle 20 drives the sleeve 19 to rotate around the connection with the installation frame 14. Since the sleeve 19 is threadedly connected with the screw rod 18, the sleeve 19 moves in the direction of separating from the screw rod 18 while rotating. The sleeve 19 drives the installation frame 14 to move in the installation groove 16 along the positioning rod 17. When the installation frame 14 moves out of the installation groove 16, the filter screen 15 can be disassembled. The installation frame 14 and the filter screen 15 that have been cleaned or replaced can be installed inside the processing box 1 by using the opposite operation.

[0032] Please refer to Figures 1-5 , as an implementation method for cleaning the inside of the discharge hopper 22: A discharge hopper 22 is fixedly arranged at the lower end of the processing box 1. A sewage discharge pipe 23 is fixedly arranged at the lower end of the discharge hopper 22. A rotating rod 24 is rotatably arranged inside the discharge hopper 22. Four connecting arms 25 are symmetrically arranged on the outer side of the rotating rod 24. Two of the connecting arms 25 on the same side are both fixedly connected with a scraping plate 26. One end of the rotating rod 24 passes through the discharge hopper 22 and is fixedly connected with a gear 27. The gear 27 is meshed with a rack 28 that is slidably connected with the discharge hopper 22 through a track structure. One end of the rack 28 is fixedly connected with an electric push rod 29 fixedly arranged on the discharge hopper 22.

[0033] Specifically, start the electric push rod 29. The electric push rod 29 drives the rack 28 to move back and forth along the sliding connection with the discharge hopper 22. The rack 28 drives the gear 27 to rotate back and forth. The gear 27 drives the rotating rod 24 to rotate back and forth. The rotating rod 24 drives the scraping plate 26 to rotate back and forth through the connecting arm 25, so that the two scraping plates 26 rotate back and forth. The scraping plate 26 contacts the inside of the discharge hopper 22, and each rotation is 90 degrees, so that the scraping plate 26 scrapes the dust and other pollutant particles adhering to the inside of the discharge hopper 22 to the sewage discharge pipe 23 and then discharges them from the sewage discharge pipe 23.

[0034] In summary, when the whole equipment is in use:

[0035] When in a state where the entire processing device needs to be used, the sewage discharge pipe 23 is in a closed state, and the exhaust fan 2 is started. The exhaust fan 2 drives the air in the processing tank 1 to flow, so that the polluted air enters the processing tank 1 from the intake pipe 5, and after being filtered by the filter net 15, it is discharged from the exhaust pipe 3 and the exhaust pipe 4. Pollutant particles such as dust intercepted by the filter net 15 will move downward under the action of gravity into the discharge hopper 22. During use, when it is necessary to clean the filter net 15, the exhaust fan 2 stops running, and the motor 12 is started. The motor 12 drives the convex column 13 to rotate. When the protruding part of the convex column 13 rotates to contact the knocking frame 8, as the convex column 13 rotates, it will push the knocking frame 8 downward, so that the knocking frame 8 moves downward along the two limiting rods 7. The knocking frame 8 drives a plurality of knocking blocks 9 to move downward to knock the filter net 15. The limiting plate 10 limits it, and the spring 11 is compressed. When the convex column 13 rotates to separate from the knocking frame 8, under the push of the spring 11, the knocking frame 8 moves back to its original position along the two limiting rods 7. By repeating this operation, the knocking blocks 9 continuously knock the filter net 15, causing the filter net 15 to vibrate, thereby knocking off the adhered dust and other pollutant particles.

[0036] When in a state where it is necessary to discharge the dust and other pollutant particles in the discharge hopper 22, the sewage discharge pipe 23 is opened, so that the dust and other pollutant particles in the discharge hopper 22 are discharged from the sewage discharge pipe 23. Then the electric push rod 29 is started, and the electric push rod 29 drives the rack 28 to move back and forth along the sliding connection with the discharge hopper 22. The rack 28 drives the gear 27 to rotate back and forth. The gear 27 drives the rotating rod 24 to rotate back and forth. The rotating rod 24 drives the scraping plate 26 to rotate back and forth through the connecting arm 25, so that the two scraping plates 26 rotate back and forth. The scraping plate 26 contacts the inside of the discharge hopper 22, and each rotation is 90 degrees, so that the scraping plate 26 scrapes the dust and other pollutant particles adhered to the inside of the discharge hopper 22 to the sewage discharge pipe 23 and then discharges them from the sewage discharge pipe 23.

[0037] When in a state where it is necessary to disassemble, clean or replace the filter net 15, turn the handle 20. The handle 20 drives the sleeve 19 to rotate around the rotation connection with the installation frame 14. Since the sleeve 19 is threadedly connected to the screw rod 18, the sleeve 19 moves in the direction of separating from the screw rod 18 while rotating. The sleeve 19 drives the installation frame 14 to move in the installation groove 16 along the positioning rod 17. When the installation frame 14 moves out of the installation groove 16, the filter net 15 can be disassembled. The installation frame 14 and the filter net 15 after cleaning or replacement can be installed inside the processing tank 1 by using the opposite operation.

[0038] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
