a sedimentation tank

Abstract

The invention relates to a sedimentation tank, comprising a tank body, a two-way screw rod is rotatably connected between two opposite inner walls of the tank body, one end of the two-way screw rod penetrates to the outside of the tank body, and the outer wall of the tank body is provided with a The motor is fixedly connected. The two opposite inner walls of the pool body are respectively provided with guide rods on both sides of the two-way screw rod. The two-way screw rod and the two guide rods run through a mud scraper. The two opposite outer walls of the body are recessed inward and form installation grooves. During the movement of the mud scraper to both sides, it can form a closed sludge treatment space with the outer wall of the corresponding installation groove, the bottom wall of the tank body and the inner walls of the three sides. The tank body The two opposite side walls of the tank are respectively penetrated with mud-cleaning holes connected with the inside of the pool body, and the outer side walls of the pool body are provided with cover plates. A sealed sludge treatment space is formed by the mud scraper and the outer wall of the installation tank, the bottom wall of the tank body and the inner walls of three sides, so that the sedimentation tank can still keep working when cleaning the sludge and improve work efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sedimentation tank. Background technique [0002] Sedimentation tank is a structure that uses sedimentation to remove suspended solids in water and is an equipment for purifying water quality. Usually, the natural precipitation or coagulation of water is used to remove suspended solids in water. Because of its simple structure, good sedimentation effect and stable working performance, it is widely used in wastewater treatment technology. [0003] The patent with the publication number CN209596627U discloses a settling tank, which includes a settling tank body, a partition plate is arranged in the settling tank body, and the settling tank body is divided into a first settling area and a second settling area by the settling plate, and the settling tank body Water inlet pipes and outlet pipes are respectively provided on both sides, and a moving device, a moving rod, a m...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: if the sludge at the bottom of the tank needs to be cleaned, it is necessary to stop the work of the sedimentation tank, then drain the water in the sedimentation tank, and then push the sludge at the bottom of the sedimentation tank to the drain through the scraper. In the mud tank, and use the mud discharge pipe to discharge the silt. Therefore, this kind of sedimentation tank cannot continue to work when cleaning the silt, which leads to a decrease in work efficiency, which needs to be improved
