Description
Technical Field
[0001] This utility model relates to the field of water curtain cabinet technology, and in particular to a spray painting water curtain cabinet. Background Technology
[0002] Spray painting is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets using pressure or centrifugal force, and then applies the spray to the surface of the object. It can be divided into air spraying, airless spraying, electrostatic spraying, and various derivative methods of these basic spraying forms, such as high-flow-rate low-pressure atomization spraying, thermal spraying, automatic spraying, and multi-group spraying.
[0003] During the spray painting process, a water curtain booth is required. A pipeline pump circulates filtered water from a tank to an upper water trough, where it overflows onto a water curtain panel, forming a water curtain. Centrifugal force from a centrifugal fan creates a vortex in the water tank, generating multiple layers of water curtain. Paint mist from the spray guns during painting is guided by suction and washed into the water. After being washed and filtered by the water curtain and water mist in a paint mist purifier, it is then collected by a filter screen in an air-water separator. This process purifies the paint mist, achieving an environmentally friendly effect and ensuring a healthy working environment for operators. However, existing water curtain booths have low paint removal efficiency, less than 30%, leading to higher VOC treatment costs. Furthermore, untreated paint mist can backflow into the workshop, impacting the working environment for employees.
[0004] In view of this, this application proposes a spray painting water curtain cabinet. Utility Model Content

[0055] Example 2
[0056] Based on Example 1, and differing from Example 1 in that,
[0057] A spray painting water curtain cabinet also includes:
[0058] The movable component 500 is used to move the bottom water tank 100 and the cabinet 200.
[0059] Reference Figure 3 and Figure 4 In a preferred embodiment, the moving component 500 includes a rectangular box 501 fixed to the lower surface of the bottom water tank 100, and a lifting plate 502 slidably disposed on the inner wall of the rectangular box 501. The lower surface of the lifting plate 502 is provided with four moving wheels 503 arranged in a rectangular array. The lower surface of the rectangular box 501 is provided with rectangular openings 504 corresponding to the four moving wheels 503. Rubber pads 505 are provided at the four corners of the lower surface of the rectangular box 501.
[0060] By installing rubber pads 505, the stability of the water curtain door during use can be effectively guaranteed.
[0061] Reference Figure 3 and Figure 4 In a preferred embodiment, the moving component 500 further includes two synchronous motors 506 symmetrically fixed on the upper surface of the rectangular box 501, and the output ends of the two synchronous motors 506 extend into the interior of the rectangular box 501 and are each fixed with a threaded post 507. The inner wall of the rectangular box 501 is fixed with two symmetrical limiting rods 508, and the upper surface of the lifting plate 502 is respectively provided with threaded holes that are threadedly connected to the outer surface of the threaded post 507, and sliding holes that are slidably connected to the outer surface of the two limiting rods 508.
[0062] By setting up a synchronous motor 506, the water curtain door can be easily moved by rotating the synchronous motor 506 in both directions.
[0063] In this embodiment, by setting the movable component 500, the water curtain cabinet can be easily moved during actual use, before installation, when its position needs to be moved.
[0064] Working Principle: During actual use, the water curtain cabinet uses an external exhaust fan to draw air from the exhaust pipe 300, allowing the paint mist generated during spraying to enter the first spray box 401 through two air inlets 405. Simultaneously, the water pump 406 activates, spraying water from the bottom water tank 100 through the first atomizing nozzle on the first spray pipe 408 to purify the paint mist. This allows the paint in the air to be adsorbed by the water and flow into the bottom water tank 100. The purified air then enters the cyclone separator 402, where any unadsorbed paint mist undergoes solid-gas separation. The air after paint separation then passes through the second spray box 403, is purified by the second spray pipe 409, and then passes through the purification box 404 where it is further purified by PP ball packing before entering the exhaust pipe 300. This effectively purifies the paint mist and improves paint removal efficiency. Furthermore, the water pump 406 draws water from the bottom water tank 100 to the outlet pipe... After 407, it can enter the horizontal pipe 4010 and the vertical pipe 4011 through the connecting pipe 4012, and flow downward through the rectangular outlet to form a three-sided water curtain. This effectively prevents the paint mist from flowing back through the cabinet 200 during the purification of paint mist. Moreover, in actual use, before installation, when it is necessary to move the water curtain cabinet, two synchronous motors 506 can be started to drive two threaded columns 507 to rotate simultaneously. The rotation of the threaded columns 507 drives the lifting plate 502 to move downward, thereby driving the four moving wheels 503 to move out of the rectangular box 501 and lifting the rectangular box 501 upward, thus achieving the purpose of easy movement of the water curtain cabinet. After moving to the designated location, the synchronous motors 506 can be started to reverse, driving the moving wheels 503 to retract into the rectangular box 501, so that the four rubber pads 505 contact the ground, ensuring the stability of the water curtain cabinet during use.
[0065] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
