Description

Technical Field

[0001] The utility model relates to the technical field of powder spraying, in particular to a spraying dust reduction device used for powder spraying. Background Art

[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).

[0003] The "a kind of spraying dust reduction device for powder spraying" disclosed in the patent network authorization publication number "CN 220110680 U" can make the fan blades rotate at high speed through the operation of the driving device in the driving box. The high-speed rotation of the fan blades can generate negative pressure in the dust suction pipe, and the horn dust suction port can generate suction to absorb dust. The driving box is provided with two dust suction boxes that can increase the suction force, and the dust suction effect can be good with the arc-shaped dust suction box. The absorbed dust can enter the dust box, and the water in the water storage tank can be transported to the dust reduction box through the operation of the water pump. After that, the water can be sprayed from the atomizing nozzle to reduce the dust. The air after dust reduction in the dust box can be discharged from the air outlet pipe. The air outlet pipe is away from the dust suction box to prevent water mist from affecting the powder spraying operation, thereby solving the problem that the existing dust reduction device mainly sprays water mist for dust reduction, which not only affects the powder spraying work, but also easily causes water accumulation on the ground, causing inconvenience to the powder spraying operation.

[0004] However, the water with dust and particulate matter attached to it is mostly discharged directly in the above-mentioned device, resulting in serious waste of water resources. Utility Model Content
