When the filter 16 in the processing box 6 on the same side of the boosting blower 3 is delivering air, the gas first contacts with the bottom surface of the filter 16, and the gas filtered by the filter 16 enters the car body 1 from the second connecting pipe 15.

[0032] Further as Figure 1 and Figure 2 As shown, it is worth noting that the cleaning components include:

[0033] The rectangular rod 19 is fixed to the inner wall of the processing box 6 , and a connecting block 20 is slidably sleeved on the outer surface of the rectangular rod 19 . A scraper rod 21 is fixed to the top surface of the connecting block 20 , and the top surface of the scraper rod 21 is in contact with the bottom surface of the filter screen 16 .

[0034] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the driving mechanism includes:

[0035] A fixed plate 9, the fixed plate 9 is fixed to the middle of the top surface of the car body 1, a driving motor 8 is fixedly mounted on one side of the fixed plate 9, and a gear 13 is fixed to the output shaft of the driving motor 8;

[0036] An L-shaped mounting rod 12 is fixed to the top surface of the car body 1, a mounting ring 25 is fixed to the end of the L-shaped mounting rod 12, a turntable 23 is rotatably connected to the inner side of the mounting ring 25, a plurality of external teeth 24 are evenly fixed to the outer surface of the turntable 23, the external teeth 24 are meshed with the gear 13 for transmission, rotating columns 22 are fixed to both sides of the turntable 23, a rectangular ring 26 is sleeved on the outer surfaces of the two rotating columns 22, a traction rod 17 is fixed to one side of the rectangular ring 26, a push rod 7 is fixed to the end of the traction rod 17, and the end of the push rod 7 is fixed to the surface of the connecting block 20.

[0038] It is worth noting that the slider 28 is limited by the limiting rod 29 and the support plate 18 to improve the stability of the rectangular ring 26 during horizontal movement.

[0040] This scheme has the following working process: the boosting and decompression treatment is adjusted in the car body 1 by the boosting blower 3 and the decompression blower 2. However, when the boosting blower 3 and the decompression blower 2 are pressurized and decompressed, the dust impurities in the gas are filtered through the filter 16 when the gas passes through the treatment box 6. After the filter 16 has been filtered for a long time, a lot of dust impurities will accumulate on its surface, which will affect the boosting and decompression work. At this time, the gear 13 is driven to rotate by the driving motor 8, and the turntable 23 is driven to rotate in the mounting ring 25 through the external teeth 24. When the turntable 23 rotates, it will drive the rotating column 22 to squeeze the rectangular ring 26, so that the rectangular ring 26 drives the traction rod 17 to move back and forth horizontally, so that the push rod 7 pushes the connecting block 20 to slide on the rectangular rod 19 horizontally, and then the scraper rod 21 cleans the dust impurities on the bottom surface of the filter 16, which facilitates the cleaning work of the filter 16.

[0041] The driving motor 8 can be purchased from the market and is equipped with a power supply. It is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
