[0030] During use, the exhaust gas is input into the treatment box 1 through the input pipe 2. When the gas is processed by the exhaust gas treatment component 4, the servo motor 31 is started to drive the transmission structure 32 to operate. Since the transmission structure 32 consists of two transmission wheels and a transmission belt assembly, the transmission structure 32 will simultaneously drive the two bidirectional screws 33 to rotate, and the bidirectional screws 33 rotate inside the treatment box 1 through the bearing 36. The two screw nuts 34 will start to move according to the thread track corresponding to the outer wall of the bidirectional screw 33. The two screw nuts located at the bottom will use the two scrapers 35 at the bottom to scrape off the impurities accumulated under the exhaust gas treatment component 4, and the two screw nuts 34 located at the top will drive the positioning plate 37 to move, and the sliding plate 38 arranged in the positioning plate 37 will repeatedly stir the material inside the exhaust gas treatment component 4, which is convenient for scraping off the accumulated impurities and avoiding the influence of the impurities on the exhaust gas treatment efficiency after accumulation. At the same time, it is also convenient to stir the filling material inside the exhaust gas treatment component 4 to ensure that the filling material is in full contact with the exhaust gas.

[0032] During use, the sliding plate 38 is pushed so that the sliding plate 38 slides on the outside of the screw nut 34 through the slot 394. As the mounting plate 392 above the sliding plate 38 slides in the mounting slot 391 inside the screw, the sliding plate 38 will gradually disengage from the positioning slot 395 above the positioning plate 37. As the height of the sliding plate 38 changes, the first bolt 393 can then be inserted into the screw nut 34.

After adjusting the position of the sliding plate 38, the storage basket 47 can be pulled, and the storage basket 47 will slide in the guide groove 46 on one side of the treatment box 1 through the guide groove 46. After the filler 48 inside the storage basket 47 is replaced, the storage basket 47 is pushed back into the treatment box 1.
