AI Technical Summary

Technical Problem

Existing backwash filters typically have only a single filter element, resulting in insufficient filtration efficiency. Impurities remain inside the filter element, making cleaning inconvenient and difficult to automate daily operations.

Method used

A multi-core automatic backwash filter is designed, which uses a filtration mechanism and a cleaning mechanism inside the cylinder. Through the cooperation of the first and second rotating discs, multi-core filtration and automatic cleaning of the filter element are achieved. The filter element is rotated and cleaned using a flexible rod and a cleaning brush, and impurities are discharged through a drain pipe.

Benefits of technology

It achieves better multi-core filtration, easy filter cleaning, and automatic and comprehensive cleaning. Impurities are discharged through the drain pipe, meeting the needs for efficient and convenient cleaning.

Abstract

The application belongs to the field of separation devices, and more particularly to the field of filters. The application discloses a multi-core automatic backwashing filter, which comprises a cylinder body, a cleaning mechanism is fixed to the inner top of the cylinder body, the cleaning mechanism comprises an oil pipe, a second piston is slidably connected in the oil pipe, a flexible shaft is rotatably connected to the bottom of the second piston, a first gear is fixed to the bottom of the flexible shaft, a flexible rod is fixed to the bottom of the first gear, the flexible rod extends into one of the filter cores, and a cleaning brush is fixed to the outer side of the flexible rod. After the liquid enters the cylinder body, it can pass through the first through hole into the filter core, the filter core can filter the liquid, the filter cores are evenly distributed between the first rotating disc and the second rotating disc in the circumferential direction, so that the filtering effect is better, and after the flexible rod and the cleaning brush are inserted into the filter core, the flexible rod and the cleaning brush rotate as a whole, so that the inside of the filter core is conveniently cleaned.
