A high-efficiency sedimentation tank

Abstract

The invention discloses a high-efficiency sedimentation tank, comprising a sedimentation tank, the bottom of the sedimentation tank is set as a funnel-shaped sedimentation tank, and a dredge pipe is installed on the bottom of the sedimentation tank, and a dredge pump is installed on the dredge pipe ; The described settling tank is also provided with several evenly arranged horizontal pipes; the described horizontal pipe is a solid structure arranged above the settling tank, and the described horizontal pipe is set to a square pipe body structure, and the horizontal pipe is set to Installed with a 45° rotation, the four corners are located at the upper, lower, left, and right positions respectively, and the horizontal tubes are arranged in an up and down staggered array. When the device is settling, the upper sludge will naturally settle from the sludge discharge slide to the lower settling tank, so that in the process of refilling sewage or pulling the sludge at the bottom, the blocking of the horizontal pipes arranged above Under this condition, the sedimented sludge will not produce reverse sedimentation phenomenon, so the sedimentation work can be completed efficiently and with high quality.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a high-efficiency sedimentation tank. Background technique [0002] The sedimentation tank in the existing structure usually adopts the shallow tank theory for sedimentation. In the structure, after the sludge is settled in the sedimentation tank, when the sludge needs to be drawn out or the sewage needs to be refilled, the water body in the sedimentation tank is often disturbed, which seriously affects the sedimentation efficiency and quality of the corresponding sedimentation tank. In the tank where the pipeline is deposited, a blocking film will appear on the surface of the pipeline over time, which will not only cause corrosion to the pipe body, but also seriously affect the sedimentation efficiency of the corresponding sludge. Most of the existing technologies cannot thoroughly clean the pipeline. SUMMARY OF THE INVENTION [0003] The purpose of...

Problems solved by technology

[0002] The sedimentation tank in the existing structure usually adopts shallow pond theory for sedimentation, and its working principle is to realize the separation of water body and sludge by installing inclined plates, inclined pipes, horizontal pipes or labyrinth sedimentation structures in the sedimentation tank; After the sedimentation tank in the structure settles the sludge, when the sludge needs to be pumped out or the sewage is refilled, it often causes disturbance of the water body in the sedimentation tank, which seriously affects the sedimentation efficiency and quality of the sedimentation tank; in addition, various In the tank where the pipeline is deposited, a layer of retardation film will appear on the surface of the pipeline over time, which will not only cause corrosion to the pipe body, but also seriously affect the sedimentation efficiency of the sludge. However, most of the existing technologies cannot thoroughly clean the pipeline
