After fixing, the movable box 5 is pushed back into the inner cavity of the dust removal box 1, and then the sealing door 2 is closed, and the outside air is allowed to pass through the air inlet mesh plate 3 through the action of the blower 4. The dust in the air is filtered out by the semicircular filter 623 arranged in the inner cavity of the mobile box 5. At the same time, the fan 63 is rotated by the rotating column 61 under the action of the blower 4, thereby driving the fixed ring 624 to rotate.
