Through the water storage tank 21, water pump 22, first connecting pipe 23, support column 24, and annular pipe 25, the water supply is completed. The water pump 22 drives the water in the water tank 21 to enter the annular pipe 25 through the first connecting pipe 23. The water inside the annular pipe 25 is sprayed into the top of the inner wall of the housing 1 through the spray nozzle 26. The misty water forms a water curtain on the top of the inner wall of the housing 1. The water curtain absorbs the paint dust splashed inside the housing 1. Through the cooperation between the first scraper 27 and the second scraper 28, the first scraper 27 and the second scraper 28 scrape off the water with paint dust adsorbed on the inner wall of the housing 1. The water with paint dust adsorbed flows into the bottom of the housing 1 under the action of gravity. Furthermore, the circulation device 3 includes a first filter plate 31, a filter screen 32, a filtration structure 33, a second connecting pipe 34, a circulation pump 35, and a circulation pipe 36; the first filter plate 31 is fixedly connected to the bottom of the support plate 7 and to the bottom of the inner wall of the housing 1; the filter screen 32 is disposed below the first filter plate 31 and is fixedly connected to the bottom of the inner wall of the housing 1; the filtration structure 33 is disposed on one side of the outer wall of the housing 1; the second connecting pipe 34 is disposed on the top of the filtration structure 33; the input end of the circulation pump 35 is connected to the top of the second connecting pipe 34 and is fixedly connected to one side of the outer wall of the housing 1; the circulation pipe 36 is connected to the output end of the circulation pump 35, and its top is connected to the side of the water storage tank 21 near the circulation pump 35; wherein, the water at the bottom of the housing 1 is filtered through the first filter plate 31, the filter screen 32, and the filtration structure 33, and the filtered water is transported back to the inside of the water storage tank 21 through the second connecting pipe 34, the circulation pump 35, and the circulation pipe 36; In the specific implementation process, it is worth noting that the first filter plate 31 is made of stainless steel, and the top of the stainless steel has several connection holes. Water at the bottom of the housing 1 flows down through the connection holes of the first filter plate 31. The filter screen 32 is a fine-pored filter cloth. Through the cooperation between the first filter plate 31, the filter screen 32 and the filter structure 33, the first filter plate 31 filters out impurities and larger paint dust particles in the water, and the filter screen 32 filters out smaller paint dust particles in the water. Through the cooperation between the second connecting pipe 34, the circulation pump 35 and the circulation pipe 36, the circulation pump 35 drives the second connecting pipe 34 to generate negative pressure. The second connecting pipe 34 draws the filtered water into the circulation pipe 36. The circulation pump 35 drives the water in the circulation pipe 36 back into the water storage tank 21. Under the action of the first filter plate 31, the filter screen 32 and the circulation pipe 36, and with the suction of the circulation pump 35, the water at the bottom of the housing 1 is circulated, preventing resource waste during the spraying process. Example 2, by Figure 1-5 It is known that the filter structure 33 includes a housing 331, a second filter plate 332, and a filter ball 333; the housing 331 is fixedly connected to the side of the housing 1 near the circulating pump 35; the second filter plate 332 is attached to the inner wall of the housing 331 near the side of the housing 1; the filter ball 333 is placed inside the housing 331; wherein, the second filter plate 332 and the filter ball 333 filter out odors and fine particles in the water, and the housing 331 stores the water; In the specific implementation process, it is worth noting that the second filter plate 332 is made of bamboo charcoal to ensure that the second filter plate 332 can meet the actual use requirements. The filter balls 333 are spheres made of activated carbon of different sizes. Through the cooperation between the box 331, the second filter plate 332 and the filter balls 333, the second filter plate 332 adsorbs small particulate molecules in the water, and the filter balls 333 adsorb odor molecules in the water, thus ensuring the filtration of odors and small particulate molecules in the water. Furthermore, the spraying device 4 includes a suction pipe 41, a delivery pump 42, a delivery pipe 43, a rotating pipe 44, a first bevel gear 45, a second bevel gear 46, a power unit 47, and a spray nozzle 48; the suction pipe 41 is disposed inside the supply box 6 and extends through the side of the supply box 6 away from the circulation pipe 36; the delivery pump 42 is connected to one end of the suction pipe 41 extending to the outside of the supply box 6 and is fixedly connected to the side of the supply box 6 away from the suction pipe 41; the delivery pipe 43 is connected to the output end of the delivery pump 42 and is fixedly connected to the bottom of the water storage tank 21; the rotating pipe 44 is rotatably connected to the bottom of the inner wall of the delivery pipe 43 through a sealed bearing and through a sealed shaft. A through-shell 1 is connected to the top of the spray pipe 5; a first bevel gear 45 is fixedly connected to the outer wall of the rotating pipe 44; a second bevel gear 46 is meshed with the outer wall of the first bevel gear 45 on the side away from the delivery pump 42; a power unit 47 is located on the side of the second bevel gear 46 away from the delivery pump 42; several spray nozzles 48 are provided, and they are equidistantly connected to the inner wall of the spray pipe 5 on the side that are close to each other; wherein, the spray pipe 5 is supplied with material through the suction pipe 41, the delivery pump 42, the delivery pipe 43, the rotating pipe 44 and the spray nozzles 48, and the spray pipe 5 is powered by the first bevel gear 45, the second bevel gear 46 and the power unit 47; In the specific implementation process, it is worth noting that the top of the spray pipe 5 is slidably engaged in the reserved groove on the top of the housing 1. A ball bearing is installed between the reserved groove and the top of the spray pipe 5. The ball bearing converts the sliding friction between the reserved groove and the top of the spray pipe 5 into rolling friction, ensuring smooth sliding between the housing 1 and the spray pipe 5 and preventing jamming when the spray pipe 5 rotates. The bottom of the suction pipe 41 is rectangular, ensuring that the suction pipe 41 can absorb the powdered paint in the supply box 6. The conveying pump 42 is a QBF type starting diaphragm pump, ensuring that the conveying pump 42 can convey the powdered paint. The power unit 47 consists of a protective shell and a motor. The motor model is selected according to actual needs, only requiring compliance with operating requirements, and the protection unit prevents external dust accumulation. To prevent debris and other contaminants from entering the motor and increasing its wear, the motor is first connected to an external power supply. The spray nozzle 48 is a 17B20 type circular nozzle. Through the cooperation between the suction pipe 41, the delivery pump 42, the delivery pipe 43, the rotating pipe 44 and the spray nozzle 48, the delivery pump 42 drives the powdered paint inside the feed box 6 to enter the delivery pipe 43 through the suction pipe 41, and then enters the spray pipe 5 through the rotating pipe 44. Through the cooperation between the first bevel gear 45, the second bevel gear 46 and the power device 47, the power device 47 drives the second bevel gear 46 to rotate, which in turn drives the first bevel gear 45 to rotate. The first bevel gear 45 drives the spray pipe 5 to rotate inside the housing 1. The spray nozzle 48 sprays the powdered paint inside the spray pipe 5 evenly onto the metal workpiece. Specifically, when performing surround spraying on metal workpieces, the operator first opens the sliding door of the housing 1, places the workpiece on top of the support plate 7, then closes the sliding door, and then turns on the water curtain by turning on the water suction pump 22 and the circulation pump 35. Then, the power unit 47 and the delivery pump 42 provide power to the spraying pipe 5, and the spray nozzle 48 performs surround spraying on the metal workpiece. After the spraying is completed, the operator takes out the metal workpiece and manually touches up any missed sprays, thin sprays, or uneven spraying areas on the workpiece surface by observation, to ensure the overall spraying effect of the metal workpiece.
