[0035] A short rod 227 is fixedly installed at the free end of the elastic telescopic rod 225, a connecting frame 228 is fixedly installed on the surface of the slide rail 222, a fixed plate 229 is fixedly installed on the surface of the connecting frame 228, a groove is opened on the top of the fixed plate 229, a rotating plate 2210 is rotatably installed on the inner wall of the groove, and a protrusion 2211 is fixedly installed on one end of the fixed plate 229 close to the slide rail 222, so that the arc scraper 226 contacts the inner wall of the processing tank 1 again, realizes back and forth scraping, and improves the service life of the equipment.

[0036] A No. 2 spring is arranged before the slider 223 slides with the slide rail 222, and the No. 2 spring drives the slider 223 to reset. The arc scraper 226 contacts the inner wall of the processing tank 1, and a No. 1 torsion spring is arranged between the groove and the rotating plate 2210, and the No. 1 torsion spring drives the rotating plate 2210 to reset.

[0037] The anti-clogging device includes an elastic telescopic plate 231, a sealing plate 232 and a support plate 233. The elastic telescopic plate 231 is fixedly installed on the inner wall of the processing tank 1, the sealing plate 232 is fixedly installed on the free end of the elastic telescopic plate 231, and the support plate 233 is fixedly installed on the bottom of the sealing plate 232. The sealing plate 232 moves downward to seal the drain pipe 6. The risk of clogging of the drain pipe 6 is reduced through intermittent discharge, thereby improving the stability of the system. In intermittent discharge, solid matter in the processing process can be more easily separated and recovered, thereby improving resource utilization.

[0038] A connecting seat 234 is fixedly installed on one side of the sealing plate 232 close to the treatment tank 1, a rotating rod 235 is rotatably installed on the inner wall of the connecting seat 234, a sliding seat 236 is slidably installed on the bottom of the inner wall of the drain pipe 6, the inner wall of the sliding seat 236 is rotatably connected to the rotating rod 235, and a clearing rod 237 is fixedly installed on the surface of the sliding seat 236 to prevent a large amount of impurities from clogging the inside of the drain pipe 6.

[0040] When the present embodiment is working, the long plate 15 moves downward to drive the long rod 221 to move downward, the long rod 221 moves downward to drive the slider 223 to move downward, the slider 223 drives the elastic telescopic rod 225 to move downward, the elastic telescopic rod 225 moves downward to drive the arc scraper 226 to move downward, and the arc scraper 226 moves downward to scrape off the particles attached to the inner wall of the treatment tank 1, so as to prevent the particles from being attached to the inner wall of the treatment tank 1 for a long time, accelerate the aging of the treatment tank 1, and also cause the flue gas treatment The effect is reduced, and the elastic telescopic rod 225 will drive the short rod 227 to move downward during the downward movement. When the short rod 227 moves to the bottom, it will be separated from the fixed plate 229. After the short rod 227 is separated from the fixed plate 229, the elastic force of the elastic telescopic rod 225 itself will drive the arc scraper 226 to shrink. The contracted arc scraper 226 will be separated from the contact with the inner wall of the processing tank 1. At the same time, the long rod 221 will drive the slider 223, the elastic telescopic rod 225 and the arc scraper 226 to rise. The rise of the elastic telescopic rod 225 will bring The short rod 227 moves upward, and the short rod 227 moves upward to contact the protrusion 2211. The vibration generated by the contact between the short rod 227 and the protrusion 2211 causes the particles attached to the arc scraper 226 to shake off, thereby preventing the subsequent scraping effect from being affected. At the same time, the short rod 227 continues to rise and contacts the rotating plate 2210. The short rod 227 pushes the rotating plate 2210 to rotate upward. When the short rod 227 is separated from the rotating plate 2210, the No. 1 torsion spring drives the rotating plate 2210 to reset. When the long rod 221 pushes again, When the elastic telescopic rod 225 and the short rod 227 move downward, the short rod 227 will contact the inclined surface of the rotating plate 2210, and the short rod 227 will be squeezed by the inclined surface of the rotating plate 2210 and move toward the inner wall of the processing tank 1. The movement of the short rod 227 toward the inner wall of the processing tank 1 will drive the free end of the elastic telescopic rod 225 and the arc scraper 226 to move toward the inner wall of the processing tank 1, so that the arc scraper 226 will contact the inner wall of the processing tank 1 again, realizing back and forth scraping, thereby improving the service life of the equipment.

[0041] The downward movement of the arc scraper 226 will push the support plate 233 to move downward, and the downward movement of the support plate 233 will drive the sealing plate 232 to move downward. The downward movement of the sealing plate 232 will seal the drain pipe 6, and the risk of blockage of the drain pipe 6 is reduced through intermittent discharge, thereby improving the stability of the system. In intermittent discharge, solid matter in the treatment process can be more easily separated and recovered, thereby improving resource utilization. At the same time, when the sealing plate 232 moves downward, it will drive the connecting seat 234 to move downward, and the connecting seat 234 will drive the rotating rod 235 to rotate downward. The downward rotation of the rotating rod 235 will squeeze the sliding seat 236 to move away from the treatment tank 1. The sliding seat 236 moving away from the treatment tank 1 will drive the dredging rod 237 to move away from the treatment tank 1. The inside of the drain pipe 6 is dredged by the dredging rod 237 moving away from the treatment tank 1 to prevent a large amount of impurities from clogging the inside of the drain pipe 6.
