The first rotating rod 402 and the second rotating rod 408 rotate together to drive the telescopic rod 410 to rotate. The telescopic rod 410 The rotation drives the scraper 404 to clean up the impurities accumulated on the surface of the filter box 403. While the scraper 404 rotates, it contacts the blocking block 412 on one side of the filter box 403, and the inclined surface set by the blocking block 412 makes the scraper 404 compress the spring 411 and the telescopic rod 410 backward in the through groove 409. Then, the spring 411 releases the elastic force to drive the scraper 404 to slide forward and quickly hit one side of the filter box 403, so that the filter box 403 vibrates, thereby knocking down the impurities accumulated on the surface of the filter box 403. At the same time, the vibration generated can also shake off the impurities adhered to the surface of the filter medium in the filter box 403. After that, the further purified waste gas passes through the second filter box 403 to filter the water, and then enters the spiral tube 602 from the second curved connecting pipe 601. The waste gas in the spiral tube 602 is cooled by the water in the water tank 7, and finally returns to the red lead production furnace body 1 from the transport pipe 603 to provide fuel for the red lead production furnace body 1, thereby realizing the recycling of waste gas.
