Sedimentation device for sewage treatment

Abstract

The invention discloses a sedimentation device for sewage treatment. The sedimentation device includes a supporting pedestal, a sedimentation chamber, a material guiding pipe, a feeding hopper and discharge pipes; the sedimentation chamber is mounted on the supporting pedestal and has a cylindrical cavity body structure having the bottom tilted to a sewage draining port; the inner wall of the sedimentation chamber is provided with guide plates A in an tilting manner; guide plates B are arranged between the guide plates A and are mounted on the material guiding pipe in an tilting manner; the material guiding pipe is mounted on the feeding hopper; the feeding hopper is mounted at the upper edge opening of the sedimentation chamber; the discharging pipes are mounted below the upper edge opening of the sedimentation chamber; the sedimentation chamber is provided with exhaust ports; the exhaust ports are located above the discharging pipes. A tank body and the material guiding pipe are adopted, and the guide plates A and the guide plates B are respectively mounted on the tank body and the material guiding pipe in the titling manner, so that the sewage flow rate is reduced, the particle adhesion area is increased, the sedimentation time and the drug use amount are reduced, the production cost is lowered, and the production efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of environmental protection equipment manufacturing, in particular to a settling device for sewage treatment. Background technique

[0002] Sewage contains a large number of suspended particles, which are usually treated by sedimentation. The suspended particles move downward under the action of gravity, so as to realize the separation of particles. In the prior art, the Chinese patent No. CN104383723A discloses a The sewage treatment device includes a tank body with an open upper end and a diversion cylinder extending into the tank from the open end. The outer wall of the body is sealed and connected, and the edge of the small end of the cone extends downward to the lower part of the tank to form a tubular part. A conduit extending out of the tank is provided at the bottom of the tank and directly below the tubular part. The upper end of the conduit Higher than the inner bottom surface of the tank body, th...
