Self-drainage sewage pipe

Abstract

A self-draining sewage pipe includes a pipe body portion and an extension section arranged on one side of the pipe body portion, A sewage discharge channel is arranged in the middle of the pipe body part, A first partition plate is arranged in the middle of the sewage discharge passage close to the sewage passage outlet, the first partition plate divides the entire sewage passage into a sewage chamber at the upper end and a first sewage chamber at the bottom, The output end of the first diaphragm is provided with a filter section, the output end of the bottom of the filter section is connectedwith the extension section, a second diaphragm is arranged at the bottom of the filter section, and a closed intermediate cavity is formed between the second diaphragm and the filter section and theextension section at the upper end. The sewage pipe of the invention can automatically remove the scum floating on the sewage surface and automatically discharge and collect the scum, thereby reducingthe sewage treatment pressure at the later stage and reducing the discharge pressure of the pipe.

Description

technical field [0001] The invention relates to the field of sewage discharge, in particular to a self-drainage sewage pipeline. Background technique [0002] When the sewage is discharged, the floating matter mixed in the sewage will cause great pressure on the discharge of the sewage pipeline, resulting in slow sewage discharge. Since the sewage needs to be filtered during the sewage discharge process, at the filter port, often A large amount of filtrate will accumulate, and these filtrates will block the entire pipeline. It is necessary to clean the filtrate at the filter frequently to prevent clogging. Or directly discharge the sewage with floating matter into the sewage plant, and then filter the sewage. This method consumes a lot of economic costs during filtration, the filtration pressure of sewage is high, and the post-processing is very inconvenient. If part of the floating objects in the sewage can be automatically separated during the sewage transmission process,...

AI Technical Summary

Problems solved by technology

This method consumes a lot of economic costs during filtration, the filtration pressure of sewage is high, and the post-processing is very inconvenient. If part of the floating objects in the sewage can be automatically separated during the sewage transmission process, it can greatly reduce the post-processing pressure.
