[0030] The working process of the exhaust gas filtering device of the PU tire production equipment in this embodiment is as follows: the exhaust gas enters the filter box 11 through the air inlet pipe 34. In the filter box 11, the exhaust gas first passes through the filter layer 19 for preliminary filtration to filter out larger particles and impurities. Then, the exhaust gas passes through the adsorption layer 21, and the harmful substances in the exhaust gas are further removed by the adsorption effect of the adsorption layer 21. As the filtration proceeds, impurities gradually accumulate on the surface of the filter layer 19, affecting the filtration effect. At this time, the screw 12 is driven to rotate by the starting motor 15. Since the screw 12 is threadedly connected to the screw hole 14 on the lifting plate 13, the rotation of the screw 12 causes the lifting plate 13 to move up and down in the filter box 11. The movement of the lifting plate 13 The cleaning brush 16 is driven to move up and down along the filter layer 19, thereby cleaning impurities on the filter layer 19, preventing the filter layer 19 from being blocked and maintaining its filtering effect. During the cleaning process, the cleaned impurities will fall into the dust box 24 in the dust box 22 at the bottom of the filter box 11 for collection. When the dust box 24 is full, the dust box 24 is slid out of the limit groove 23 by the handle 38 for cleaning. If the internal filter layer 19 and the adsorption layer 21 need to be replaced and maintained, the locking buckle 30 is opened to release the limit fixation of the sealing cover 29, so that the sealing cover 29 is rotated open along the pin shaft 28, so as to facilitate the extraction of the filter layer 19 and the adsorption layer 21 in the first slot 18 and the second slot 20 for replacement or maintenance.
