[0025] Working principle: When the exhaust gas generated during the zinc oxide production process flows into the air pipe 25 and the interior of the mounting frame 1, the particulate matter in the exhaust gas can be filtered through the two filter screens 7 on the outer wall of the mesh tube 6; The motor 20 and the first synchronous wheel 21 drive the two first drive shafts 12 to rotate, and the first cleaning sleeve 13 is driven to rotate through the first drive shaft 12. The first drive shaft 12 drives the second drive shaft 14 to rotate through the first gear 16, and the second drive shaft 14 drives the second cleaning sleeve 15 to rotate; The first driving shaft 12 drives the output shaft 22 to rotate through the second synchronous wheel 23, and the output shaft 22 drives the second gear 24 to rotate, and the ring gear 18 is driven to rotate through the second gear 24, and the mesh drum 6 is driven to rotate through the ring gear 18. When the mesh drum 6 rotates, the filter screen 7 located in the mounting frame 1 is rotated to the outside. At this time, the inner wall and the outer wall of the filter screen 7 respectively generate friction with the first cleaning sleeve 13 and the second cleaning sleeve 15, so that the particles blocked in the mesh of the filter screen 7 can be cleaned. At the same time, the cleaned filter screen 7 located outside the mounting frame 1 is quickly rotated to the inside of the mounting frame 1, so that the filter screen 7 can be quickly replaced, which can avoid interrupting the normal operation of the device; By installing the first cleaning sleeve 13 and the second cleaning sleeve 15 on the outside of the mounting frame 1 respectively, and opening corresponding second chip removal holes 9 and first chip removal holes 8 on the tray 3 below the first cleaning sleeve 13 and the second cleaning sleeve 15, the dust generated during the cleaning process can be discharged into the collection tube 27, thereby preventing the dust generated during the cleaning process from being re-absorbed into the mounting frame 1; By pulling the pull ring 45, the arc plate 43 is driven to move through the pull ring 45, so that the rubber plug 44 is pulled out from the third chip removal hole 28, and the arc plate 43 drives the connecting rod 38 to move through the second support block 42. Under the elastic support of the spring 39, the first support block 41 drives the guide plate 46 to move, and the guide plate 46 drives the tooth plate 49 to move, and the tooth plate 49 drives the two third gears 32 to rotate, and the third gears 32 respectively drive the rotating shaft 29 to rotate, and the connecting arms 30 are respectively driven to rotate through the rotating shaft 29, and the connecting arms 30 respectively drive the first cleaning brushes 31 to rotate, and the two first cleaning brushes 31 generate friction along the inner wall of the collecting tube 27, so that the dust accumulated in the collecting tube 27 is gathered between the two first cleaning brushes 31; When the guide plate 46 moves, it drives the support frame 34 to move, and the support frame 34 drives the slide bar 36 to slide along the inner wall of the limit plate 37.

When the slide plate 40 moves, it drives the second cleaning brush 48 to slide between the two connecting arms 30, and the dust between the two connecting arms 30 is discharged from the third chip removal hole 28; Loosen the pull ring 45. Under the elastic force of the spring 39, the arc plate 43 pushes the rubber plug 44 into the third chip removal hole 28, thereby sealing the collection tube 27. At the same time, under the torsion force of the torsion spring 33, the rotating shaft 29 drives the connecting arm 30 to rotate in the opposite direction until the two connecting arms 30 fit together, which can prevent dust from accumulating between the two connecting arms 30 and causing dust uncleanness.
