After sedimentation, there will be silted impurities at the bottom of the sedimentation tank. The impurities need to be cleaned by hand with hand tools, which takes a long time.

[0003] After searching, the Chinese patent publication number CN218961859U discloses "a sedimentation tank for sewage treatment, including a tank body, a bottom plate, and a pressure plate. A scraper ring is fixedly connected to the surface of the pressure plate. After the sewage is precipitated through the tank body, when it is necessary to clean the accumulated impurities inside, the bolt is rotated, the bolt is separated from the limit piece, the limit piece loses its fixation and rotates 180 degrees, the limit piece is separated from the sealing plate, and the sealing plate is flipped over to open the tank body."

[0004] The above patent drives the disk to rotate by a motor to move the pull rope, and the pull rope drives the pressure plate and the scraper ring to move downward, so that the pressure plate squeezes the accumulated impurities downward to discharge the accumulated impurities from the discharge port of the pool body; however, when introducing sewage, this patent cannot reduce the volume of some large impurities in the sewage even by squeezing, which causes the large volume to block the drain port.
