AI Technical Summary

Technical Problem

Existing automatic backwashing membrane filters require long-term shutdowns during the backwashing process, resulting in reduced system processing capacity, increased energy consumption, and equipment wear. Furthermore, frequent shutdowns and restarts increase management complexity and costs.

Method used

An automatic backwashing membrane filter was designed. By rotating the filter tube counterclockwise through a rotating component, the filter tube is connected to the inlet water pipe for reverse flushing, reducing downtime and cleaning during the filtration process, thereby improving treatment efficiency and lifespan.

Benefits of technology

It effectively reduces downtime, improves wastewater treatment efficiency, extends the service life of filter tubes, and reduces operating and management costs.

Abstract

This utility model belongs to the field of wastewater treatment technology, specifically an automatic backwashing membrane filter with high-efficiency wastewater treatment capability. It includes a conveying pipe, a second sealing ring fixedly connected to the middle of the top of the conveying pipe, a partition fixedly connected to the middle of the inner side of the conveying pipe, a bottom sealing base fixedly connected to the top of the conveying pipe, a filter assembly disposed on the inner side of the top of the bottom sealing base, a second connecting pipe fixedly connected to the top right of the conveying pipe, and a first sealing ring fixedly connected to the left side of the top of the second connecting pipe. This utility model provides an automatic backwashing membrane filter with high-efficiency wastewater treatment capability. By rotating the assembly, the third connecting pipe and the filter pipe rotate counterclockwise, thereby rotating the used filter pipe backward and connecting the front end of the third connecting pipe and the filter pipe to the second connecting pipe for continued filtration. This significantly reduces downtime and improves wastewater treatment efficiency.
