Radial-flow sedimentation tank convenient for sediment cleaning

Abstract

The invention belongs to the technical field of sewage treatment, in particular to a radial-flow sedimentation tank convenient for sediment cleaning. The sedimentation tank comprises a circular reservoir; a central column is arranged in the circular reservoir; a water inlet pipe and a sludge discharge pipe are mounted on the circular reservoir; a drainage groove is formed in the circular reservoir; a cross beam is rotationally mounted on the central column; a walking device is mounted on the cross beam; an L-shaped mounting frame is mounted on the cross beam; a mud removing mechanism is mounted on the L-shaped mounting frame; the mud removing mechanism comprises a mud scraping plate, an accommodating groove, a first transfer cylinder and a second transfer cylinder which are fixedly connected; the accommodating groove and the second transfer cylinder are both communicated with the first transfer cylinder; first sealing plates are fixedly mounted at the two ends of the accommodating groove and the first transfer cylinder; a mud rotating paddle is mounted on the first sealing plate and used for solving the problems that in the sediment cleaning process of an existing sedimentation tank, when the sediment amount is large, sediment is accumulated and slides along the mud scraping plate to fall behind the mud scraping plate, so that the mud scraping plate difficultly concentrates thesediment to the middle of the bottom of the tank, and the cleaning efficiency is low.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a radial flow sedimentation tank which is convenient for cleaning bottom mud. Background technique [0002] Radial flow sedimentation tank half-bridge peripheral drive scraping sludge activated sludge method ideal supporting equipment for sedimentation tank in the sewage treatment process is suitable for primary sedimentation tank or secondary sedimentation tank, the main function is to remove the sludge deposited in the sedimentation tank and Floating debris on the surface of the water. At present, the radial flow sedimentation tank generally includes a circular tank body and a sludge scraper in the tank body. There is a sludge bucket at the bottom of the tank body, and a sludge discharge pipe is provided on the side wall of the sludge bucket. The sludge at the bottom of the pool can be scraped into the sludge hopper, and then discharged through the sludge ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a radial flow sedimentation tank that is easy to clean up the bottom mud, which is used to solve the problem that when the bottom mud amount is large, the bottom mud is accumulated along the scraping line during the cleaning process of the existing sedimentation tank. The plate slides and falls behind the scraper, which makes it difficult for the scraper to concentrate the sediment to the middle of the bottom of the pool, and the cleaning efficiency is low
