When the piston plate 24 moves upward, the one-way valve on the air inlet pipe closes, and the gas in the air tank 4 moves in the direction of the air outlet pipe 12. When the T-shaped plate 19 blocks the air outlet pipe 12, the gas in the air tank 4 will be compressed to generate high pressure, until the dial plate 18 and the T-shaped plate 19 are in contact and the T-shaped plate 19 moves upward. At this time, the rectangular groove 20 and the air passage 22 are connected, so that the high-pressure gas in the air tank 4 will be accelerated to be sprayed out, further cleaning the blockage of the holes formed by the annular filter screen 23 and the strip-shaped mesh plate 16, and the high-pressure gas after storage can clean the blockage more thoroughly. When the holes are cleaned, the rotating slide column 32 will return to the arc-shaped groove 34 from the C-shaped groove 33, further reducing the size of the holes formed by the annular filter screen 23 and the strip-shaped mesh plate 16, facilitating subsequent rolling of the agglomerated catalyst raw materials. In summary, the blockage of the holes formed by the annular filter screen 23 and the strip-shaped mesh plate 16 can be automatically and continuously cleaned by reciprocating, and the holes can be cleaned by changing the size of the holes and the high-pressure gas after storage, which will not damage the annular filter screen 23 and the strip-shaped mesh plate 16, and improve the cleaning effect of the mesh holes.
