[0050] The suction assembly 4 includes a plurality of side tubes 401 disposed on one side wall of the processing box 101 and a plurality of side tubes 404 disposed on the other side wall of the processing box 101. The side wall of the processing box 101 is provided with openings corresponding to the side tubes 401 and the side tubes 404 respectively. A slide plate 402 is sealed and slidably disposed inside the side tube 401. A slide plate 405 is sealed and slidably disposed inside the side tube 404.

[0051] The rotating assembly 3 includes a slide groove 301 arranged on the outside of the connecting plate 406, and a side plate 305 is installed on the side wall of the processing box 101. A rotating rod 306 is rotatably connected to the side plate 305, and one end of the rotating rod 306 is connected to a turntable 304. A rotating column 303 is provided on the outer edge of the turntable 304. An active block 302 that slides and cooperates with the slide groove 301 is rotatably provided on the rotating column 303.

[0052] In this embodiment, the vacuum pump guides the exhaust gas in the paint spraying room into the treatment box 101 through the air inlet pipe 102, and the water pump 204 extracts the spray water from the bottom of the treatment box 101 through the water guide pipe 203 and guides it to several spray pipes 201 respectively. The spray water in the spray pipe 201 is atomized and sprayed through the atomizing nozzle 202, which can settle the water-soluble or large particle components in the exhaust gas. At the same time, the rotating motor 309 drives the worm 308 to rotate, and the worm 308 drives the rotating rod 306 to rotate synchronously by meshing with the worm wheel 307. The rotating rod 306 drives the rotating column 303 to rotate by driving the rotating disk 304 to rotate. The rotating column 303 drives the rotating column 303 by rotating with the movable block 302 and sliding with the slide groove 301. The connecting plate 406 reciprocates in the horizontal direction. When the connecting plate 406 approaches the side wall of the processing box 101, the connecting plate 406 drives the slide plate 1 402 and the slide plate 2 405 to move to the left through the moving rod 403. The slide plate 1 402 increases the space on the right side of the slide plate 1 402 inside the side tube 1 401 by moving to the left, thereby reducing the air pressure on the right side of the slide plate 1 402 inside the side tube 1 401. The slide plate 2 405 reduces the space on the left side of the slide plate 2 405 inside the side tube 2 404 by moving to the left, thereby increasing the air pressure on the left side of the slide plate 2 405 inside the side tube 2 404, so that the gas inside the processing box 101 flows into the side tube 1 401, and the gas inside the side tube 2 404 flows into the processing box 101. When the connecting plate 406 is far away In the process of leaving the side wall of the treatment box 101, the connecting plate 406 drives the slide plate 1 402 and the slide plate 2 405 to move to the right through the moving rod 403. The slide plate 1 402 reduces the space on the right side of the slide plate 1 402 inside the side tube 1 401 by moving to the right, thereby increasing the air pressure on the right side of the slide plate 1 402 inside the side tube 1 401. The slide plate 2 405 increases the space on the left side of the slide plate 2 405 inside the side tube 2 404 by moving to the right, thereby reducing the air pressure on the left side of the slide plate 2 405 inside the side tube 2 404, so that the gas inside the treatment box 101 flows into the side tube 2 404. The gas inside the side tube 1 401 flows into the treatment box 101, which can effectively increase the flow rate of the exhaust gas in the treatment box 101, thereby increasing the gap between the exhaust gas and the spray droplets. The relative speed can improve the waste gas treatment efficiency. At the same time, the suction of the gas inside the side tube 1 401 and the side tube 2 404 can increase the coverage radius of the spray, so that it can cover a wider area, and the suction operation can reduce the suspension time of the droplets in the air, which helps to maintain the activity and wetness of the droplets and improve the contact efficiency between the droplets and the gas.

During the movement of the moving rod 403 to the left, the moving rod 403 drives the second rotating rod 602 to rotate counterclockwise by engaging the tooth groove 601 with the transmission gear 603. The second rotating rod 602 drives the stirring plate 604 to rotate synchronously to stir the gas in the processing box 101. During the movement of the moving rod 403 to the right, the moving rod 403 drives the second rotating rod 602 to rotate counterclockwise by engaging the tooth groove 601 with the transmission gear 603. 3 meshing mode drives the second rotating rod 602 to rotate clockwise, and the second rotating rod 602 stirs the gas in the processing box 101 by driving the stirring plate 604 to rotate synchronously, which is convenient for the rapid contact between the exhaust gas and the droplets, improves the purification efficiency of the exhaust gas, realizes the linkage between the suction component 4 and the stirring component 6, reduces the energy consumption, and improves the practicality of the device.

The water pump 204 draws out the spray water at the bottom of the treatment box 101 through the water guide pipe 203 and guides it to several spray pipes 201 respectively. The spray water in the spray pipe 201 is sprayed out by the atomizing nozzle 202, which can settle the water-soluble or large particle components in the waste gas.

[0061] The rotating motor 309 drives the worm 308 to rotate, and the worm 308 drives the rotating rod 1 306 to rotate synchronously by meshing with the worm wheel 307. The rotating rod 1 306 drives the rotating column 303 to rotate by driving the rotating disk 304 to rotate. The rotating column 303 drives the connecting plate 406 to reciprocate in the horizontal direction by rotating with the movable block 302 and sliding with the sliding groove 301. When the connecting plate 406 approaches the side wall of the processing box 101, the connecting plate 406 drives the slide plate 1 402 and the slide plate 2 405 to move to the left through the moving rod 403. The slide plate 1 402 increases the space on the right side of the slide plate 1 402 inside the side tube 1 401 by moving to the left, thereby reducing the air pressure on the right side of the slide plate 1 402 inside the side tube 1 401. The slide plate 2 405 reduces the space on the left side of the slide plate 2 405 inside the side tube 2 404 by moving to the left, thereby increasing the air pressure on the left side of the slide plate 2 405 inside the side tube 2 404.

In the process of the connecting plate 406 moving away from the side wall of the treatment box 101, the connecting plate 406 drives the slide plate 1 402 and the slide plate 2 405 to move to the right through the moving rod 403. The slide plate 1 402 reduces the space on the right side of the slide plate 1 402 inside the side tube 1 401 by moving to the right, thereby increasing the air pressure on the right side of the slide plate 1 402 inside the side tube 1 401. The slide plate 2 405 increases the space on the left side of the slide plate 2 405 inside the side tube 2 404 by moving to the right, thereby reducing the air pressure on the left side of the slide plate 2 405 inside the side tube 2 404, so that the gas inside the treatment box 101 flows into the side tube 2 404, and the gas inside the side tube 1 401 flows into the treatment box 101, which can effectively increase the flow rate of the exhaust gas in the treatment box 101, thereby increasing the relative speed between the exhaust gas and the spray droplets, and improving the exhaust gas treatment efficiency;

[0062] At the same time, during the movement of the moving rod 403 to the left, the moving rod 403 drives the rotating rod 2 602 to rotate counterclockwise by means of the meshing of the tooth groove 601 and the transmission gear 603, and the rotating rod 2 602 stirs the gas in the treatment box 101 by driving the stirring plate 604 to rotate synchronously. During the movement of the moving rod 403 to the right, the moving rod 403 drives the rotating rod 2 602 to rotate clockwise by means of the meshing of the tooth groove 601 and the transmission gear 603, and the rotating rod 2 602 stirs the gas in the treatment box 101 by means of the meshing of the tooth groove 601 and the transmission gear 603, which facilitates the rapid contact between the exhaust gas and the droplets, improves the purification efficiency of the exhaust gas, realizes the linkage between the suction component 4 and the stirring component 6, reduces energy consumption, and improves the practicability of the device. Through a plurality of spoiler holes 605, it is convenient to turb the gas during the rotation of the stirring plate 604 to avoid blind spots caused by unidirectional stirring of the gas.
