Description

Technical Field

[0001] The present application relates to the technical field of exhaust gas filtration in automobile paint shops, and in particular to an exhaust gas filtration device for automobile paint shops. Background Art

[0002] Automobile painting has high technical content and plays a vital role in automobiles. However, the coating process also produces the largest amount of exhaust gas. The exhaust gas generated by the automobile paint room needs to be purified and meet the standards before it can be discharged. Therefore, an automobile painting exhaust gas filter device is needed when the automobile painting exhaust gas is discharged.

[0003] After checking the announcement number: CN220715304U, a waste gas filtering and emission device is disclosed. This technology discloses "including a waste gas treatment chamber, the waste gas treatment chamber includes a chamber body, the right side of the chamber body is connected to an air inlet pipe, the left side of the chamber body is connected to an air outlet pipe, the top of the chamber body is installed with an upper buckle plate embedded in a groove, the front of the chamber body is installed with a door panel, the left side of the inner wall of the chamber body is installed with a telescopic component, and the right side of the telescopic component is installed with a filter component and other technical solutions, which has the function of injecting waste gas into the water tank so that the water flow inside the water tank can humidify and filter the waste gas, avoiding too much waste gas directly impacting the filter cotton column, affecting the filtering effect of the filter cotton column on the waste gas, and humidifying the waste gas can also prevent tiny particles in the gas from being filtered by the filter cotton column, thereby ensuring the filtering effect of particles in the waste gas and other technical effects."

[0004] With respect to the above-mentioned related technologies, the inventor believes that the device still has the following problems:

[0005] First, the device uses a filter component and a humidification component to filter the exhaust gas, but a bin body and a door panel are directly provided on the outside of the filter component of the device, which makes the device prone to exhaust gas leakage when in use.

[0006] Secondly, the device uses a diverter pipe to divert the exhaust gas to achieve the effect of separating the exhaust gas for filtration, but the diverter pipe is not provided with a drainage structure, which makes the device directly unusable when it needs to be cleaned.

[0007] In response to the above problems, the inventors proposed an exhaust gas filtering device for automobile paint shops to solve the above problems. Utility Model Content

[0021] The opening and closing mechanism 4 includes a fixed plate 407, which is fixedly mounted on one side of the gas pipeline 5. The top of the fixed plate 407 is rotatably connected to a rotating handle 406. One end of the rotating handle 406 is movably connected to a support rod 405. Push plates 404 are fixedly mounted on both sides of the support rod 405. The two sides of the two push plates 404 are rotatably connected to a first connecting rod 403 and a second connecting rod 408. The bottom end of the first connecting rod 403 is fixedly mounted with a rotating shaft 402. The rotating shaft 402 is rotatably mounted between the upper and lower inner walls of the gas pipeline 5. The rotating shaft 40 2 is fixedly installed with a first baffle 401, and the other side of the rotating shaft 402 is rotatably installed with a second baffle 409. The first baffle 401 and the second baffle 409 are both arc-shaped. The top of the second baffle 409 is fixedly connected to the second connecting rod 408. Pull the rotating handle 406, and the rotating handle 406 drives the two push plates 404 on both sides to move. The push plates 404 use the first connecting rod 403 and the second connecting rod 408 to drive the first baffle 401 and the second baffle 409 on the lower side to block one side of the gas pipeline 5, so that one side of it can be repaired.

[0022] Working principle: First, rotate the closing cover 204.
