Then the cover plate 3 is kept closed under the constraint of the hinge 2. The ventilation mechanism 4 and the refrigeration mechanism 5 work together, and the conducting pipe 6 is conducted to the ventilation hopper 8 through the three-way valve 7. The dust is filtered through the filter screen 10 for ventilation and heat dissipation. When the filter screen 10 needs to be cleaned, the closed threaded cover 11 and the ventilation threaded cover 12 are respectively screwed and removed from the outer side of the corresponding external threaded ring 9, and are interchangeably installed after the filter screen 10 is removed. At this time, another group of filter screens 10 are used for continuous filtering.
