These waste gases are directly discharged into the air, which will cause air pollution, so they need to be treated. The Chinese utility model type patent with the public document number: CN213643266U discloses a waste gas treatment device with an anti-clogging structure. In this document, when the filter needs to be cleaned, the output end of the servo motor will drive the driving rod to rotate, and then the driving rod will drive the plastic brush plate to rotate, so that the plastic brush plate cleans the filter. The cleaned pollutants will fall into the inside of the drain slot, effectively avoiding the phenomenon of clogging of the filter when it is in use;

[0022] like Figure 1 , Figure 2 and Figure 3As shown, the outer brush plate 508 is fixedly connected to the bottom surface of the filter cartridge 502, the outer bristles 509 are fixedly connected to the outer brush plate 508, the inner brush plate 511 is fixedly connected to the upper position of the outer brush plate 508, the inner bristles 512 are fixedly connected to the inner brush plate 511, the connecting chamber 517 is fixedly connected to the side position of the filter box 1, and the transparent water pipe 518 is fixedly connected to the connecting chamber 517. The filter assembly 5 also includes a support column 510, the outer bristles 509 are in contact with the outer surface of the filter cartridge 502, the inner bristles 512 are in contact with the inner surface of the filter cartridge 502, and the inner brush plate 511 is fixedly connected to the outer brush plate 508 through the support column 510. The filter assembly 5 also includes a water inlet pipe 513 and a water inlet valve 514. The water inlet pipe 513 is fixedly connected to one side of the filter box 1. The water inlet valve 514 is movably installed on the water inlet pipe 513, and the filter assembly 5 also includes a water outlet pipe 515 and a water outlet valve 516. The water outlet pipe 515 is fixedly connected to the other side of the filter box 1, and the water outlet valve 516 is movably installed on the water outlet pipe 515. The handle 506 is rotated to make the filter cartridge 502 rotate synchronously, so that the inner and outer sides of the filter cartridge 502 are brushed by the inner bristles 512 and the outer bristles 509, so as to clean the filter cartridge 502 more thoroughly and make the filter cartridge 502 less likely to be blocked. The outer bristles 509 and the inner bristles 512 are in contact with clean water or immersed in clean water, so that during the cleaning process, the cleaned dust can easily enter the clean water, and the dust can be brought out of the filter box 1 by discharging the clean water, making the dust cleaning more convenient.

[0023] The rubber seal ring 501 is provided on the air inlet pipe 2, and the rubber seal ring 501 and the side of the filter cartridge 502 are squeezed against each other to seal the contact surface.

The filter cartridge 502 filters the air intake through the filter hole 503 at the side. The lower position of the filter box 1 is filled with some clean water through the water inlet pipe 513, so that the clean water soaks the lower end of the filter cartridge 502, and the inner bristles 512 and the outer bristles 509 are convenient for contacting with the clean water. When the contact surface of the filter cartridge 502 that contacts the air inlet pipe 2 is blocked or blocked, the handle 506 is rotated to make the rotating rod 504 rotate through the No. 1 bearing 505, and the filter cartridge 502 rotates synchronously. The contact surface is switched and the handle 506 is continuously rotated so that the inner and outer sides of the filter cartridge 502 are continuously brushed by the inner bristles 512 and the outer bristles 509, thereby facilitating the cleaning of the dust on the inner and outer sides of the filter cartridge 502. Since the lower position of the filter cartridge 502 is immersed in clean water, the dust and impurities brushed out easily enter the clean water. By opening the water outlet valve 516 on the water outlet pipe 515, the clean water in the box is discharged, thereby discharging the dust together, thereby achieving the dust cleaning treatment in the filter box 1. New clean water is replaced through the water inlet pipe 513, and the transparent water pipe 518 at the side position is observed to facilitate the observation of the water level in the filter box 1 to prevent the water level from exceeding the height of the air intake pipe 2. The filter cartridge 502 switches the contact surface with the air intake pipe 2 so that the new side contacts the air intake pipe 2, so that the normal operation of the air intake pipe 2 is not easily interrupted, and the air intake pipe 2 continues to maintain the air intake filtration work through the new contact surface on the filter cartridge 502.
