[0030] The principle of implementing the present invention is as follows: the air in the workshop is sucked and transmitted through the operation of the fan 6. The air enters from the open end of the box body 1, that is, passes through the air inlet swing plate 2 arranged in a rectangular shape, enters the interior of the box body 1, and is sucked and transmitted from the water tank 9 through the transmission box 7, and then transmitted to the water curtain box 16, and finally released through the nozzle 17 to form a water curtain. The air passes through the water curtain, and impurities in the air can be degraded and removed, and finally mixed in the water in the water tank 9. In this process, the driving motor 15 works, and the water curtain box 16 moves back and forth under the gear rack transmission, that is, the water curtain box 16 arranged in an array moves back and forth, so that the water curtain is fully in contact with the air; after passing through the water curtain, the air is further filtered by the filtering mechanism, specifically, the micro particles in the air are removed by the filter layer 23. After the use of the moving cycle, the motor 1 3 and the motor 2 4 work to control the winding drum 1 21 and the winding drum 2 2 to rotate, that is, drive the filter layer 23 to move, realize the conversion of the filter area, and maintain a good filtering effect.

[0031] After the impurities in the air are degraded and mixed in the water tank 9, the salvage frame 13 is located at the bottom of the water tank 9. The motor 3 11 works and the hoisting drum 12 rotates to retract and release the hoisting rope 10, thereby continuing to lift the salvage frame 13 and the salvage filter layer 14, and salvage the impurities in the water through the salvage filter layer 14 and salvage them out of the water. Then, the telescopic rod of the fixed electric cylinder 901 cooperates with the fixing hole on the side of the salvage frame 13 to fix the salvage frame 13 so that the salvage frame 13 is in a stable state; the blocking electric cylinder 25 controls the movement of the blocking plate 2501, that is, releases the blocking state of the side of the box body 1, and the extension motor 28 works to move the extension screw rod 29, that is, the scraper rod 31 moves to the inside of the box body 1, and the position of the scraper rod 31 is controlled by the position electric cylinder 26, so that the scraper rod 31 contacts the surface of the salvage filter layer 14, and then the extension screw rod 29 is controlled to move, that is, the scraper rod 31 moves on the surface of the salvage filter layer 14 to scrape off the salvaged impurities.

[0032] Furthermore, air passes through the air inlet swing plate 2 arranged in a rectangular shape, and impurities and dust adhere to the air inlet swing plate 2. The belt motor 33 can be used to drive the belt structure 32 to move, that is, to drive the push slide 36 to reciprocate, and the push wheel 3601 pushes the pushing part 3501, so that the moving slide 35 reciprocates. Under the connecting action of the connecting rod 34, the air inlet swing plate 2 swings back and forth to shake off the impurities and dust attached to the air inlet swing plate 2, thereby eliminating manual cleaning operations.
