[0028] The vibration structure 6128 comprises a rotating drum 61281 arranged at the right side of the connecting rod 6125, a connecting ring 61282 movably sleeved at the outer side of the rotating drum 61281, a convex shaft 61283 fixedly connected to the inner side of the upper end of the connecting ring 61282, a transmission groove 61284 arranged at the outer side of the rotating drum 61281, connecting plates 61285 fixedly connected to the upper and lower sides of the connecting ring 61282, elastic shafts 61286 arranged at the sides of the connecting plates 61285 away from the connecting ring 61282, and support rods 61287 transversely inserted into the connecting plates 61285 and connected with the upper and lower ends of the support 6127.

[0031] The working principle is as follows:

[0032] When the treatment of coating exhaust gas is to be realized, the gas inlet 2 provided on the left side of the box 1 can be used to realize the introduction of the exhaust gas. When the exhaust gas enters the inside of the box 1, it can be filtered and purified with the filter screen 4 provided inside the box 1, and the filtered gas will be discharged through the gas outlet 3 provided on the right side of the box 1.

[0033] In order to further improve the treatment of coating exhaust gas, the filter cleaning device 6 is provided on the left side inside the box 1. First, the external water pipe is connected to the connecting pipe 65 through the flange 66. In this way, the external water flow can enter the spraying shelf 67 through the connecting pipe 65. The spraying shelf 67 is used to spray and settle the exhaust gas entering the settling tank 61. In this way, the coating exhaust gas is pretreated to reduce the particulate impurities in the coating exhaust gas. The particulate generated by the spraying and settling will fall into the collecting tank 64 through the discharge port 63. The screen mesh provided at the bottom of the collecting tank 64 can realize solid-liquid separation to realize the recycling of water resources. The collected particles can be cleaned by pulling out the collecting tank 64. The air after the settling treatment can be discharged through the through hole 62 provided on the right side of the settling tank 61 and then contact the filter screen 4 provided inside the box 1 to realize deep filtration and purification treatment. In this way, the efficient treatment of coating exhaust gas can be realized to reduce the influence on the external environment and the workers.

[0034] Secondly, when spraying and settling, the motor 611 provided at the upper end of the box body 1 can be driven to rotate the multi-groove driving wheel 610 at the bottom. As the multi-groove driving wheel 610 rotates, the transmission belt 69 connected to the outer side of the multi-groove driving wheel 610 will realize the rotation of the multi-groove driven wheel 68 on the left side. In this way, the connecting pipe 65 can then realize the rotation of the spraying frame 67 connected to the bottom, thereby increasing the spraying and settling range. Secondly, when the multi-groove driving wheel 610 rotates, it docks with the multi-groove driving wheel 61 The rotating shaft 6122 at the lower end of the 0 rotates synchronously therewith, and realizes the rotation of the first bevel gear 6123 connected to the outer side of the bottom. As the first bevel gear 6123 rotates, the second bevel gear 6124 meshing with the lower end of the first bevel gear 6123 can realize the synchronous rotation of the internal transverse plug-in connecting rod 6125. When the connecting rod 6125 rotates, the scraper 6126 symmetrically installed on the outer side of the connecting rod 6125 rotates to realize the scraping and cleaning of the left side of the filter 4, and to scrape the impurities attached to the outside of the filter 4. Clean, scrape and clean the impurities that fall down, and can be quickly discharged along the sewage outlet 5 provided at the lower end of the box body 1. In this way, the filter screen 4 can be scraped and cleaned synchronously when the sedimentation spraying activity is in progress, thereby reducing the problem of filtration blockage of the filter screen 4. At the same time, the drum 61281 docked on the right side of the connecting rod 6125 will rotate at the same time. During the rotation of the drum 61281, the transmission groove 61284 opened on the outside of the drum 61281 and the convex shaft 61283 provided on the upper end of the inner part of the connecting ring 61282 can be used to connect the drum 61281. The connecting ring 61282 is made to move back and forth laterally along the outside of the rotating drum 61281. In this way, the connecting plates 61285, which are symmetrically arranged on the outside of the connecting ring 61282, will realize the reciprocating impact between the elastic shaft 61286 and the filter 4 through the support and guidance of the laterally connected support rods 61287, so that the filter 4 produces a certain vibration effect to shake off the impurities attached to the outside of the filter 4. Therefore, the scrapers 6126 rotating on both sides can cooperate with the vibration effect of the filter 4 to achieve efficient cleaning of the attached impurities and reduce the problem of insufficient cleaning.
