Horizontal self-overturning efficient sedimentation tank

Abstract

The invention discloses a horizontal self-overturning efficient sedimentation tank. A plurality of partition plates are arranged in the tank body to divide the tank body into a plurality of water inlet areas and a plurality of settling areas from left to right; a plurality of water distribution ports are formed in the partition plates; a plurality of horizontal turning plates are arranged in eachsettling area and are positioned at the water distribution port; a rotating shaft is arranged in the settling area close to the partition plates; the rotating shaft is horizontally arranged and parallel to the partition plates; the horizontal turning plate is located on the rotating shaft and can rotate along the rotating shaft, one end of the horizontal turning plate is placed on the partition plates at the water distribution ports, the other end of the horizontal turning plate is a mud falling end, and the area of the horizontal turning plate located at the water distribution port with the rotating shaft as a partition line is smaller than that of the mud falling end. The innovative points of the invention are as follows: the movable settling area is increased in the tank body so that the settling efficiency is increased, and the problem that the inclined pipe filler is blocked due to sludge adhesion is solved by utilizing instantaneous self-overturning sludge discharge.

Description

technical field [0001] The invention relates to the field of sedimentation tanks, in particular to a horizontal self-turning high-efficiency sedimentation tank. Background technique [0002] At present, the well-known ideal precipitation theory is that the precipitation removal rate of suspended particles is related to the sedimentation area of ​​the sedimentation tank, and has nothing to do with the depth of the sedimentation tank (of course, it should not be too shallow to prevent short stay, re-emergence of sediment and the influence of surface wind blowing) ), increasing the sedimentation area can reduce the size of the sedimentation velocity μ0 for a specific particle. Therefore, in theory, the larger the sedimentation area, the better, but in actual projects, the area is often very compact, and the area will affect the project investment. Affect the profit of the operating enterprise. Therefore, measures that do not increase or even reduce the floor space will be a m...

Problems solved by technology

[0004] The innovation point of the present invention is that by increasing the movable sedimentation area in the tank body without increasing the floor area of ​​the body, while increasing the sedimentation efficiency, it also uses instantaneous "self-turning mud discharge" to solve the problem of sludge sticking and blocking inclined pipe fillers The problem
