[0002] Powder spraying is the process of spraying powder coating onto the surface of a workpiece using powder spraying equipment. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating. The powdery coating is leveled and solidified through high-temperature baking to become a final coating with different effects (different types of powder coating effects). In order to avoid waste during the spraying process, the powder will be recycled after spraying, so the powder needs to be absorbed and clean air discharged at the same time.

[0027] By adopting the technical solution of this embodiment, the exhaust fan 12 is used to exhaust the air inside the filter box 1, and the dust enters the filter box 1 from the air inlet pipe 14 and reaches the filter plate 13. After the filtered air passes through the lower side of the filter plate 13 and the dust is collected, the exhaust fan 12 is turned off and the filter plate 13 is pulled out. During the process of pulling the filter plate 13 out, the dust falls from the filter plate into the receiving frame 16 at the bottom of the filter box 1. At the same time, the atomizing nozzle 202 is turned on and sprays mist to prevent the dust from floating in the filter box 1. After the dust is sprayed, it can fall into the collecting frame 16 in time. At the same time, when the dust is taken out, the dust can also be prevented from flying. The guide plate 15 is used to slide the dust from the upper side of the water tank 201 into the receiving frame 16.

[0036] Reference Figure 3 : A first handle 133 is integrally connected to the outer side of the filter plate 13.

[0037] In this embodiment, the first handle 133 is used to pull out the filter plate 13 .

[0038] Reference Figure 2 : A second handle 161 is provided on the outer side of the material receiving frame 16.

[0039] In this embodiment, the second handle 161 is used to more conveniently pull out the material receiving frame 16 .

[0040] Reference Figure 2 : The water inlet of the water tank 201 is located on the upper side of the water tank 201, and the water inlet is connected to the outside of the filter box 1.

[0041] In this embodiment, the water in the water tank 201 enters from the filter box 1 .

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
