The sealing plate 44 has a cavity 6 inside, and the cavity 6 has a buckle assembly 7.
[0020] Please see Figure 3 The buckle assembly 7 includes two sets of sliding plates 72 slidably connected within the cavity 6. A guide groove is provided on the left side wall of the cavity 6. Each set of sliding plates 72 has a guide block on its left side wall that matches the guide groove.

[0021] Working principle: When the powder coating equipment performs electrostatic powder coating on the workpiece, some powder will not be used and will float in the equipment. The dust pump 21 draws the powder into the dust collection box 20. Under the action of the explosion-proof one-way valve 22, the powder backflow explosion can be prevented. Under the action of the filter element 24, the dust can be filtered and adsorbed. When it is necessary to collect and recycle the dust adsorbed on the surface of the filter element 24, the operator pulls the pull block 73 to drive the sliding plate 72 to move relative to it. The sliding plate 72 drives the spring 71 to stretch. The sliding plate 72 drives the insertion rod 70 to move from the insertion hole 46 to the cavity 6, and then pulls the sealing plate 44 outward, thereby removing the filter element 24 from the dust collection box 20, and then collecting and recycling the dust adsorbed on the filter element 24.
