Sedimentation tank

Abstract

The invention relates to a sedimentation tank, which comprises a pool body, a bidirectional screw rod is rotationally connected between two opposite inner walls of the tank body; one end of the two-way screw rod penetrates through the exterior of the pool body; a motor fixedly connected with the end part of the bidirectional screw rod is arranged on the outer wall of the tank body; guide rods arearranged on the two opposite inner walls of the pool body and on the two sides of the two-way lead screw respectively; a mud scraping plate penetrates through the bidirectional screw rod and the two guide rods; the mud scraping plate is in threaded connection with the bidirectional screw rod; two opposite outer walls of the pool body are sunken inwards to form mounting grooves. In the process thatthe mud scraping plates move towards the two sides, the outer walls of the corresponding mounting grooves, the bottom wall of the pool body and the inner walls of the three sides can form a closed mud treatment space, wherein mud cleaning holes communicating with the interior of the pool body penetrate through the two opposite side walls of the pool body correspondingly, and a cover plate is arranged on the outer side wall of the pool body. A sealed sludge treatment space is formed by the sludge scraping plate, the outer wall of the mounting groove, the bottom wall of the tank body and the inner walls of the three sides, the sedimentation tank can still work when sludge is cleaned, and the working efficiency is improved.

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
