[0022] With the above structure, when in use, the suction pump is turned on so that the exhaust gas is sucked into the air inlet pipe 2, and then discharged from the exhaust pipe 3 after passing through the filter plate 5. When the filter plate 5 needs to be cleaned, first release the fixed connection between the second sealing plate 17 on one side and the rectangular sliding frame 4, then push the rectangular sliding frame 4 to slide to a suitable position, and then seal the other second sealing plate 17 with the rectangular sliding frame 4 through the fixing component, and drive the two rectangular sliding blocks 6 to move horizontally to a suitable position synchronously through the sliding component. When the two rectangular sliding blocks 6 are in motion, the two cleaning components are driven to rotate synchronously through the rotating component to clean the replaced filter plate 5, and foreign matter is collected through the collecting component, and at the same time, the first sealing plate 15 is driven to move horizontally to a suitable position synchronously to prevent gas from escaping.

[0023] like Figure 3 As shown, the sliding assembly includes two screw rods 7, and the relative inner walls of the rectangular sliding frame 4 are provided with sliding grooves. The two ends of the two screw rods 7 are rotatably installed on the relative inner walls of the two sliding grooves, and the two screw rods 7 are connected by a transmission unit. The two rectangular sliding blocks 6 are respectively threadedly installed on the two screw rods 7. The advantage of such an arrangement is that the two rectangular sliding blocks 6 can be driven to move synchronously through the arrangement of the two screw rods 7.

[0024] Specifically, when the two screw rods 7 rotate synchronously, the two rectangular sliders 6 are driven to move horizontally synchronously under the action of the threads, thereby driving the cleaning assembly to move horizontally synchronously, thereby cleaning the filter plate 5 .

The advantage of such an arrangement is that through the arrangement of the gear 13 and the spur rack 14, the mounting shaft 12 can be driven to rotate through the meshing action of the gear 13 and the spur rack 14.

[0030] Specifically, when the mounting shaft 11 and the gear 13 move horizontally synchronously, the gear 13 and the spur rack 14 mesh with each other to drive the gear 13 and the mounting shaft 11 to rotate synchronously, thereby driving the cleaning roller brush 11 to rotate and clean the filter plate 5.

[0031] like Figure 4 As shown, the collecting assembly includes a collecting box 16, which is fixedly mounted on the side of the first sealing plate 15. The collecting box 16 is adapted to the filter plate 5. The advantage of such an arrangement is that the foreign matter under cleaning can be collected through the arrangement of the collecting box 16.

[0032] Specifically, when the cleaning roller brush 11 is cleaning the filter plate 5, the collecting box 16 moves horizontally synchronously to collect the collected foreign matter, which is convenient for subsequent cleaning by the staff.

[0033] like Figure 1 As shown, the fixing assembly includes a first magnetic block 18 and a second magnetic block 19. A mounting hole is provided on the side of the second sealing plate 17, and the first magnetic block 18 is fixedly installed in the mounting hole.
