[0017] (III) Beneficial Effects
[0018] This utility model provides a cyclone spray booth, which has the following beneficial effects:
[0019] 1. Highly efficient paint mist capture: The cyclone spray booth utilizes the principle of cyclones to create a rotating airflow within the cyclone chamber, effectively separating the paint mist from the air and capturing it in a water tank at the bottom of the spray booth. The packing material separates the water (containing paint mist) from the air. This paint mist capture method significantly improves efficiency, greatly reducing residual paint mist in the air and improving the air quality of the spray booth.
[0020] 2. Environmental protection and energy saving: Because the cyclone spray booth can efficiently capture paint mist and exhaust harmful gases, improving exhaust quality, it can reduce environmental pollution; at the same time, the water pipes in the spray booth are circulating pipes, which greatly saves water resources and effectively reduces the generation of wastewater.
[0021] 3. Convenient, simple and safe operation: The operation of the cyclone spray booth is relatively simple and is equipped with a ventilation system. Operators only need to adjust the spraying equipment and ventilation system to carry out spraying operations. Good ventilation can promptly expel harmful gases and odors generated during the spraying process to the outside, and also help reduce the accumulation of paint mist in the spray booth, reducing the risk of fire and explosion. At the same time, the maintenance of the spray booth is also relatively convenient, requiring only regular cleaning of the water tank and replacement of the filter media. Attached Figure Description

A cyclone spray booth includes a main body, which forms horizontally adjacent spray painting operation areas and paint mist purification areas, as well as a water tank 5 connecting the bottoms of the spray painting operation areas and the paint mist purification areas. Specifically, on the side of the paint mist purification area facing the spray painting operation area, there are interconnected overflow channels 13, connecting plates 14, and water curtain plates 9 arranged from top to bottom. The front and rear sides of the overflow channels 13, connecting plates 14, and water curtain plates 9 are respectively tightly sealed to the front and rear side walls of the main body, that is, the overflow channels 13, connecting plates 14, and water curtain plates 9 together constitute a partition structure separating the spray painting operation area and the paint mist purification area.
[0029] The painting operation area is equipped with a paint spray gun 4 and a conveyor 3 that transports the workpiece P to the painting station; the top of the painting operation area is provided with a filter layer 2 and a pressure equalization layer 1 from bottom to top.

The support plate is inclined, which on the one hand can reduce the opening size of the gas path and guide the gas through the first spray 7a, and on the other hand, it is used to support the first spray 7a.
[0032] The secondary cyclone purification zone is equipped with a cyclone tank 8, and a second spray 7b is installed inside the cyclone tank 8.
