AI Technical Summary

Technical Problem

Existing circulating water treatment devices suffer from problems such as easy clogging of filters, incomplete cleaning, and the need for frequent manual maintenance. In particular, they cannot achieve simultaneous cleaning of the inner and outer walls of the filter screen.

Method used

Design a circulating water treatment device that uses a multi-section telescopic sealing sleeve to drive a scraper assembly, combined with a spring reset structure, to clean the inner wall of the filter screen using liquid or gas pressure, and to clean the outer wall by linking a steel wire rope with a ring scraper, thus achieving synchronous scraping of the inner and outer walls.

Benefits of technology

It effectively prevents filter clogging, reduces the frequency of manual maintenance, extends the continuous operation time of the equipment, cleans thoroughly and is easy to maintain, and avoids secondary pollution and dead corner residues caused by traditional cleaning.

Abstract

This invention discloses a circulating water treatment device, including a housing and a filter screen. The filter screen is installed inside the housing, and a scraper assembly is located in the upper part of the housing corresponding to the inside of the filter screen. An inlet pipe and a liquid inlet pipe are connected to the upper and lower parts of the housing, respectively. An outlet pipe is connected to the outer wall of the housing. The inlet pipe is connected to the scraper assembly, and the liquid inlet pipe corresponds to the inside of the filter screen. The scraper assembly includes a circular scraper and a multi-section telescopic sealing sleeve. A spring is also provided between the upper part of the housing and the circular scraper. The circular scraper is adapted to the inner wall of the filter screen. When liquid or gas is injected into the multi-section telescopic sealing sleeve through the inlet pipe, the multi-section telescopic sealing sleeve extends and retracts, driving the circular scraper to clean the inner wall of the filter screen. This invention can simultaneously clean the inner and outer walls of the filter screen, effectively preventing filter screen clogging, reducing the frequency of manual maintenance, and achieving simultaneous reverse scraping of the inner and outer walls of the filter screen under a single power source drive. It has high cleaning efficiency and advantages such as thorough cleaning, convenient maintenance, and ease of use.
