Electric inclined tube settling tank

Abstract

The invention relates to an electric inclined tube settling tank. The electric inclined tube settling tank comprises a settling tank, a plurality of steel frameworks are arranged in the settling tank; a plurality of inclined tubes are laid in each framework, so that an inclined tube frame is formed; a rail is further erected at the top of the settling tank; the inclined tube frame is fixedly connected with a pulley positioned on the rail; the inclined tube frames in the same row in the settling tank are fixedly connected with one another through steel pieces and are driven through the same vibrator; a sludge zone is arranged at the bottom of the settling tank. Managerial personnel in a waste water treatment station starts the electric vibrator according to the thickness of accumulated sediments on the inclined tubes, so as to remove the sediments on the inclined tubes, the normal use state of the inclined tubes is kept, the optimal solid-liquid separation effect of the settling tank can be achieved, and the electric inclined tube settling tank has the characteristics of high convenience in use, high efficiency, high automation degree and the like.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and relates to an electric inclined tube sedimentation tank in which inclined tubes are laid in a sedimentation tank or a clarification tank to separate sediment in wastewater. Background technique [0002] In the process of wastewater treatment, it is necessary to use sedimentation tanks or clarification tanks to separate the sediment in the wastewater. In order to speed up the sedimentation, inclined pipes are often laid in the sedimentation area, called inclined pipe sedimentation tanks. In the sedimentation zone of the flat flow or vertical flow sedimentation tank, the sedimentation tank is divided into a series of shallow sedimentation layers by using inclined parallel pipes or parallel pipes (sometimes honeycomb fillers can be used), and the treated and settled sediments are deposited in each Mutual movement and separation in shallow layers. Between every two parallel sloping ...

AI Technical Summary

Problems solved by technology

[0008] Under a certain pH condition, high-valent ions such as aluminum and iron are hydrolyzed to form flocculent precipitates, which are adsorbed on the inclined tube and are not easy to move downward, and accumulate more and more, eventually filling the inclined tube and making it impossible to continue operation

It can only stop the wastewater treatment and clean the inclined tube. Because the inclined tube is very difficult to clean and it is not easy to clean, the separation efficiency of the inclined tube sedimentation tank is reduced.

[0009] As far as the applicant knows, the authorization number is CN2014105890442, which is named as a battery production wastewater treatment system, and the authorization number is CN201420532920.3, which is named as an integrated sewage treatment device, both of which refer to the existing inclined tube sedimentation tank described in the background technology, but All have nothing to say about the specific structure, and are completely different from the content to be protected by this application
