A radial flow sedimentation tank for easy cleaning of sediment

Abstract

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 sediment, comprising a circular storage tank, a central column is installed in the circular storage tank, and a water inlet pipe and a drain are installed on the circular storage tank. The mud pipe, the drainage groove is installed in the circular reservoir, the beam is installed on the center column, the walking device is installed on the beam, the L-shaped mounting frame is installed on the beam, and the desilting mechanism is installed on the L-shaped mounting frame. The mechanism includes a mud scraper fixedly connected, a holding tank, a first transfer cylinder and a second transfer cylinder, both of the storage tank and the second transfer cylinder are connected with the first transfer cylinder, and the two ends of the storage tank and the first transfer cylinder are fixedly installed with The first sealing plate is equipped with a mud turning paddle, which is used to solve the problem that when the amount of sediment in the existing sedimentation tank is large, the sediment accumulates and slides along the scraper and falls on the scraper. Behind the mud plate, it is difficult for the mud scraper to concentrate the bottom mud to the middle of the bottom of the pool, 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
