When the operator aligns the dust hood 5 on the dust suction pipe 4 with the packaging area of ​​dry mortar, the fan 7 works under the control of the controller 2 to suck the dust that escapes during the packaging of dry mortar into the dust collection box 1 through the dust hood 5 and the dust suction pipe 4. The dust in the dust collection box 1 is blocked by the filter screen 33 and falls into the dust collection hopper 8. The airflow passes through the filter screen 33, flows through the exhaust pipe 6, and is discharged from the dust collection box 1 through the fan 7. When it is observed through the glass observation window 12 on the door 11 that a certain amount of dust has been collected inside the dust collection box 1, the valve 10 is opened and the collected dust is discharged from the dust collection box 1 through the discharge pipe 9. Installation mechanism 3 includes a limiting groove 31, a frame 32, a filter 33, a sliding groove 34, a locking block 35, a slot 36, a drive assembly 37, and a sealing assembly 38.

The dust in the dust collection box 1 is blocked by the filter screen 33 and falls into the dust collection hopper 8. The airflow passes through the filter screen 33, flows through the exhaust pipe 6, and is discharged from the dust collection box 1 by the fan 7. When a certain amount of dust is observed collected inside the dust collection box 1 through the glass observation window 12 on the switch door 11, the valve 10 is opened, and the collected dust is discharged from the dust collection box 1 through the discharge pipe 9. When it is observed through the glass observation window 9 that the filter screen 33 needs cleaning, the switch door 11 is opened, and then the rotating disc is rotated. 375 drives the lead screw 374 to rotate. Under the restriction of the limit rod 372 and the sliding hole 373, the rotation of the lead screw 374 drives the movable plate 371 to move downward along the sliding groove 34. The locking block 35 moves accordingly and disengages from the slot 36, releasing the fixation of the frame 32. Then the frame 32 and the filter screen 33 can be pulled out from the limit groove 31. After the filter screen 33 is cleaned, the frame 32 is reinserted between the two limit grooves 31 until the rear side of the frame 32 contacts the sealing gasket 382. At this time, the outer surface of the sealing ring 381 contacts the inner wall of the limit groove 31. Then the rotating disk 375 is rotated in the opposite direction, causing the locking block 35 to be reinserted into the slot 36, fixing the filter screen 33 in the dust collection box 1 through the frame 32. Then the switch door 11 can be closed to continue the dust removal work.
