[0025] In order to scrape away the sludge deposited on the bottom wall and side wall of the sedimentation tank 1, refer to Figure 3The mud discharge mechanism 5 includes a scraper 51, a fixed sleeve 52 is fixedly connected to the upper right end of the outer surface of the scraper 51, and a threaded pin 53 is threadedly connected to the front part of the inner cavity of the fixed sleeve 52, which can clamp and fix the connecting column 62 extending to the inner cavity of the fixed sleeve 52.
