Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts painting, in particular to a self-cleaning painting booth. Background Technique

[0002] A painting booth is a chamber specifically for painting operations. It can timely remove the paint mist generated during the spraying process, creating good painting conditions and working environments for the spraying process in the painting workshop. It is a key equipment in the painting workshop. Currently, the painting equipment for manufacturing automobile parts usually adopts a Venturi painting booth. The painting operator stands on the ground or a platform to operate. During painting, a part of the splashed paint mist will fall into the water tank, and the other part is adsorbed by the Venturi effect. The water in the water curtain collides with, adsorbs, and condenses the paint mist into water droplets containing paint mist. When the water droplets pass through the baffle plate, the water droplets containing paint mist and other moisture are separated and enter the water tank, and the purified air is discharged outdoors through the exhaust pipe above.

[0003] However, during actual use, some paint mist will be adsorbed on the surface of the baffle plate. Long-term accumulation is likely to cause the air duct to be blocked. Currently, it is usually cleaned by manually opening it, but the installation space of the baffle plate is narrow, making cleaning inconvenient. Content of the Utility Model

[0031] The water vapor separation chamber 1 further includes a frame body 15, a water curtain assembly 16, a water curtain water supply unit 17, a suction air unit, and a plurality of baffle plates 11. The plurality of baffle plates 11 are arranged at intervals up and down on the frame body 15. The water curtain assembly 16 is located on one side of the frame body 15. The water curtain assembly 16 and the frame body 15 enclose a suction air space. The suction air unit is located at the top of the suction air space and is communicated with it. The water curtain assembly 16 includes at least one water curtain unit 161. The water curtain unit 161 includes an overflow trough 1611 arranged on the frame body 15 and a water curtain plate 1612 arranged on one side of the overflow trough 1611. The water outlet of the water curtain water supply unit 17 faces the upper overflow trough 1611 and is used to supply water to the overflow trough 1611. The water curtain plate 1612 in the lower water curtain unit 161 is arranged at an interval from the water tank 3 to form a water vapor inlet. As Figure 5 shown, to increase the collision effect, the inclination directions of two adjacent baffle plates 11 are opposite.

[0032] As Figure 2 、 Figure 3 and Figure 5 shown, the water vapor separation chamber 1 further includes a cleaning assembly 12 and at least one set of flushing assemblies 13. Each set of flushing assemblies 13 includes a water supply pipeline 131 and a plurality of nozzles 132. The water supply pipeline 131 is respectively communicated with the plurality of nozzles 132 to supply water to the nozzles 132. The plurality of nozzles 132 are respectively arranged corresponding to the plurality of baffle plates 11 one by one to flush the baffle plates 11. The cleaning assembly 12 includes a plurality of cleaning units 121. The plurality of cleaning units 121 are respectively arranged corresponding to the plurality of baffle plates 11 one by one. Each cleaning unit 121 includes a scraper and a driving member 1213. The driving member 1213 drives the scraper to move along the surface of the baffle plate 11 to scrape the paint mist on the baffle plate 11. Thus, it is convenient to clean the paint mist on the baffle plate 11, improves the cleaning efficiency of the baffle plate 11, and further avoids the blockage of the air duct in the suction air space in the water vapor separation chamber 1.

[0033] As Figure 3 and Figure 4As shown in the figure, to improve the cleaning efficiency of the baffle 11, the scraper includes a moving plate 1211 and two scraping bars 1212. The moving plate 1211 extends along the length direction of the baffle 11 and is perpendicular to the baffle 11. The moving plate 1211 is of an annular structure and is provided with through holes along its length direction. The two scraping bars 1212 are respectively arranged on the upper and lower hole walls of the through holes of the moving plate 1211 and extend along the length direction of the through holes. The two scraping bars 1212 can respectively abut against the upper and lower side surfaces of the baffle 11. Sliding grooves 111 are formed on both sides of the baffle 11 in the length direction and along its width direction. Both sides of the moving plate 1211 in the length direction penetrate through the sliding grooves 111. The driving member 1213 drives the moving plate 1211 to reciprocate along the extending direction of the sliding grooves 111 to scrape the paint mist on the upper and lower side surfaces of the baffle 11 through the scraping bars 1212, thereby being able to clean the paint mist on the upper and lower side surfaces of the baffle 11 simultaneously and improving the cleaning efficiency. To avoid damage to the baffle 11, the scraping bar 1212 is a rubber scraping bar 1212.

[0034] To improve the stability of the movement of the moving plate 1211 in the scraper, each cleaning unit 121 includes two driving members 1213. The driving members 1213 are respectively located at both ends of the baffle 11 in the length direction, and the fixed ends of the driving members 1213 are connected to the side walls of the frame body 15. The telescopic ends of the driving members 1213 are connected to the moving plate 1211 in the scraper.

[0035] As Figure 3 shown in the figure, in this embodiment, the self-cleaning spray painting booth includes two groups of flushing assemblies 13. The two groups of flushing assemblies 13 are arranged at intervals along the length direction of the baffle 11, and a plurality of spray heads 132 in each group of flushing assemblies 13 are respectively arranged in one-to-one correspondence with the baffle 11. The water inlet ends of the water supply pipes in the two groups of flushing assemblies 13 are both communicated with the water pump 14. It should be noted that a pressurizing structure is provided in the flushing assembly 13, and the water supply pipes provide high-pressure water for the spray heads 132 to provide a certain impact force of water on the baffle 11 and then flush the baffle 11.

[0036] In this embodiment, to improve the adsorption of the paint mist in the spray painting chamber 2 by the water curtain, the water curtain assembly 16 includes two water curtain units 161 arranged up and down. The water curtain plate 1612 in the upper water curtain unit 161 is connected to the overflow tank 1611 in the lower water curtain unit 161 through a connecting plate 162.

[0037] Working principle: The overflow tank 1611 is supplied with water through the water curtain water supply unit 17. The water flow forms a water curtain after passing through the water curtain plate 1612. The water curtain collects the paint mist in the air. The air suction unit sucks air upward. The water droplets with paint mist enter the air suction space through the water vapor inlet. After the water droplets with paint mist pass through the baffle 11, the water droplets containing paint mist and other moisture are separated and enter the water tank 3. The purified air is sucked out through the air suction unit, and part of the paint mist is adsorbed onto the baffle 11. Since the self-cleaning spray booth includes a cleaning component 12 and at least one set of flushing components 13, a plurality of nozzles 132 of the flushing component 13 are respectively arranged in one-to-one correspondence with a plurality of baffles 11 to flush the baffle 11. A plurality of cleaning units 121 of the cleaning component 12 are respectively arranged in one-to-one correspondence with a plurality of baffles 11. The driving member 1213 drives the scraper to move along the surface of the baffle 11 to scrape off the paint mist, thereby facilitating the cleaning of the paint mist on the baffle 11, improving the cleaning efficiency of the baffle 11, and thus avoiding the blockage of the air duct in the air suction space in the water vapor separation chamber 1.
