Description

Technical Field

[0001] This utility model relates to the field of spray painting equipment technology, specifically to a self-cleaning adsorption device and a spray booth including the self-cleaning adsorption device. Background Technology

[0002] In the painting process, in order to ensure that the surface of the parts is completely coated with paint, it is usually necessary to spray paint onto the surface of the parts to be painted from various angles. Therefore, during the painting process, harmful gases will inevitably be dispersed in the gas environment inside the spray booth (painting room). In order to ensure the health of the workers' working environment and reduce the toxic and harmful substances in the exhaust gas, and to ensure the environmental performance of the production line, it is usually necessary to purify the exhaust gas generated in the spray booth.

[0003] Currently, the exhaust gas treatment system of spray booths typically employs a combination of water curtain, water vortex, and packing water-blocking processes. Specifically, a water curtain device is used to separate a purification chamber on the rear side of the spray booth. The water pump of the water curtain device sprays circulating water to form a water curtain. Excess paint mist generated during the spraying process collides with the water curtain as it passes through the water curtain device, and some paint mist particles are adsorbed by the water film and sink to the bottom water tank. The water vortex treatment unit in the purification chamber uses high-speed rotating water-containing airflow to come into counter-current contact with the small amount of escaped paint mist exhaust gas, which is fully dissolved and sinks to the bottom water tank, further purifying the exhaust gas. The packing water-blocking unit at the top of the purification chamber stores a large number of multi-faceted hollow spherical packings. The packings are always directly above the water vortex treatment unit, which can further filter the paint mist and moisture in the exhaust gas, thereby ensuring the cleanliness of the exhaust gas.

[0004] However, with prolonged use, solidified paint residue gradually adheres to the surface of multi-faceted hollow sphere packing, requiring periodic manual disassembly and replacement. The frequent replacement of packing in the water-blocking unit to ensure effective waste gas treatment leads to high manual maintenance costs. Furthermore, packing replacement necessitates a complete production line shutdown, resulting in poor production line continuity and impacting normal production efficiency. In addition, the thick layer of solidified paint residue on the replaced packing surface makes it impossible to clean thoroughly and reuse, leading to wasted packing resources and increased environmental costs for the company.

[0005] Therefore, how to provide a spray booth purification structure that facilitates the cleaning of the filler has become a technical problem that urgently needs to be solved in this field. Utility Model Content

The first output shaft of the reducer 720 is formed as a first rotary power unit, and the second output shaft of the reducer 720 is formed as a second rotary power unit. The rotary motor 710 can drive the first rotary power unit and the second rotary power unit to rotate, so as to drive the drive wheel 210 and the second coupling 311 to rotate respectively.

[0096] In this embodiment of the utility model, the same rotary motor 710 drives the reducer 720 with two output shafts to operate, thereby realizing the movement of two sets of components, namely the rotary drive assembly 200 and the swing mechanism 310, which reduces the overall maintenance probability of the equipment and saves component costs.

[0099] As a preferred embodiment of this utility model, such as Figure 2 As shown, the self-cleaning adsorption device also includes a plurality of guide structures 630 distributed along the length of the swing beam 320. Each guide structure 630 includes a guide seat 631 and a cover plate 632. The guide seat 631 is fixedly mounted on the fixing frame 600. A guide groove extending along a preset axis is formed in the guide seat 631.

The swing beam 320 passes through the guide holes of the plurality of guide structures 630.

[0100] Optionally, such as Figure 2 As shown, the cross-sectional shape of the swing beam 320 is rectangular, and correspondingly, the cross-sectional shape of the guide hole in the guide structure 630 is also rectangular.

[0101] In other embodiments of this utility model, the cross-sectional shape of the swing beam 320 may also be hexagonal, trapezoidal or other non-circular shapes.

[0102] Optionally, such as Figure 2 As shown, the guide structure 630 is fixedly mounted on the connecting seat 620.

The spray booth and the purification chamber are connected through the water curtain device 20. The self-cleaning adsorption device 30 is disposed in the spray booth.

[0104] Understandably, the water curtain device 20 is used to spray circulating water (cleaning liquid) to form a water curtain. When the exhaust gas in the paint spraying booth enters the purification chamber through the water curtain, it collides with the water curtain, causing some paint mist particles to be adsorbed by the water film, thus achieving preliminary purification.

[0105] Optionally, such as Figure 7 As shown, the spray booth also includes multiple water vortex treatment units 40. The water vortex treatment units 40 are located in the purification chamber and below the self-cleaning adsorption device 30. The water vortex treatment units 40 can drive the gas in the purification chamber to move upward and spray circulating water into the airflow, so that the circulating water comes into reverse contact with a small portion of the escaped paint mist exhaust gas and dissolves it, further purifying the exhaust gas.

[0106] Optionally, such as Figure 7 As shown, the spray booth also includes a water tank 50, which is located below the water curtain device 20 and the water vortex treatment unit 40, and is used to recycle circulating water.

[0107] Optionally, such as Figure 6 As shown, the spray booth also includes multiple circulating fans 60, which are located on the top of the chamber 10 and are used to extract the gas above the self-cleaning adsorption device 30 to the outside of the spray booth.

[0108] Optionally, the circulating fan 60 can also be used to transport the gas in the cleanroom to the paint booth to achieve internal circulation of the clean gas.

Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
