Its performance can meet the use requirements of dust suction in a spray paint room;

[0015] (2) The device is placed in a paint spraying room, the dust hood is aligned with the position where the powder is generated, and then the first motor is turned on by an external power supply, so that the first motor drives the dust fan and the first sprocket to rotate rapidly. The rotation of the dust fan generates suction, so that the dust hood transports the powder to the inside of the dust suction chamber through the Z-shaped dust suction pipe and the dust delivery hood. At this time, the inhaled dust will be filtered and intercepted by the filter, and the gas will be discharged through the dust fan and the first air outlet;

[0016] The rotation of the first sprocket will drive the exhaust fan to rotate through the first chain and the second sprocket, and the rotation of the exhaust fan will transport the powder entering the dust removal water chamber toward the rotating circular baffle. At the same time, the first rotating shaft drives the circular baffle to rotate to wet the surface of the circular baffle. The powder will stick to the surface of the wet circular baffle and mix into the liquid inside the dust removal water chamber, and the air can be effectively discharged through the vent hole, the air guide hole and the second air outlet.

[0017] (3) By starting the second motor, the first rotating shaft and the two third bevel gears are rotated through the three fourth sprockets, the three second chains and the three third sprockets. The rotation of the first rotating shaft drives the circular baffle to rotate, so that the surface of the circular baffle is soaked, and the powder is adhered to the surface of the soaked circular baffle and mixed into the liquid inside the dust removal water chamber;

[0018] The rotation of the two third bevel gears will drive the first rotating shaft and the first worm gear through the two second bevel gears. The rotation of the first worm gear will cause the first worm gear to rotate and drive the gear column and the first bevel gear. The rotation of the gear column will cause the two rolling brushes to rotate to clean both sides of the filter. At the same time, the rotation of the first worm gear will cause the first bevel gear to rotate and transmit the rotation of the conical gear ring. The rotation of the conical gear ring will drive the connecting ring and the filter to rotate, so that the roller rotates inside the groove ring and the filter rotates stably, so that the position of the filter aligned with the dust suction power suction port is rotated and removed, and the rotating filter will contact the two rotating rolling brushes to effectively perform the cleaning operation, so that the surface of the filter remains effectively clean and the filtering operation can be continuously and effectively performed.

[0019] When the gear column rotates, it drives the two first gears to rotate, and the rotation of the two first gears drives the two plug shafts to rotate, and the rotation of the two plug shafts drives the two rolling brushes to rotate to clean the two sides of the filter screen, so that the powder falls to the bottom of the groove plate; and in the cleaning process, the rotation of the exhaust fan causes the powder to be sucked into the dust removal water chamber through the connecting pipe for dust removal.

[0020] The rotation of the first rotating shaft will drive the disc and the arc-shaped rack to rotate, and the rotation of the arc-shaped rack will transmit the two racks in turn, so that the two racks drive the inverted U-shaped block to move up and down, and the up and down reciprocating movement of the inverted U-shaped block will drive the two plug-in shafts, the two rolling brushes and the two first gears to move up and down synchronously, so that the two first gears move up and down on the surface of the tooth column and maintain effective meshing transmission, and the up and down reciprocating movement of the two rolling brushes will contact both sides of the filter screen, so that the two rotating and reciprocating rolling brushes can clean the two side surfaces of the rotating filter screen.
