Innovative backwashing filter and application thereof

Abstract

The invention discloses an innovative backwashing filter and an application thereof. The innovative backwashing filter comprises a filter body, a filter screen assembly and a filter element assembly;the filter body is provided with a main water inlet, a first water outlet, a backwashing water outlet and a filter element assembling opening; the filter screen assembly is provided with a filter screen raw water side and a filter screen purified water port, the filter screen raw water side is communicated with the main water inlet, and a rotary drainage blade is arranged at a correspondingly communicated transition position of the filter screen raw water side and the main water inlet; the backwashing water outlet corresponds to the filter screen raw water side; and the filter element assemblyis installed on the filter element assembly opening, the filter screen purified water port is communicated with the raw water side of the filter element assembly through the filter body, and the water purification side of the filter element assembly is communicated with the first water outlet. The innovative backwashing filter ingeniously avoids the backwashing requirement of the filter element assembly, realizes simple, convenient and automatic cleaning of the filter screen assembly, and the filter element part has the advantages of simplicity, material saving and low cost.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to an innovative backwash filter and its application. Background technique [0002] The filter refers to the filter equipment placed in the water inlet pipe, which can filter impurities in the water such as sediment, rust, floating objects, etc., can improve the water quality, and can also protect the equipment. The core of the filter is the filter element assembly. In order to improve the life of the filter element assembly, an effective measure is to use backwash to clean the filter element assembly so that it can be recycled to a certain extent. [0003] At present, regarding the backwashing treatment of the filter element assembly, the usual method is to change the direction of water flow inside and outside the filter element assembly, and realize backwashing by switching the waterway. In this way, it is usually necessary to design related valve body components to realize switc...

AI Technical Summary

Problems solved by technology

In this way, it is usually necessary to design related valve body components to realize switching, and the structural design is relatively complicated

[0004] In addition, the filter also has the following disadvantages in practical application: first, the filter element assembly usually needs to be replaced regularly, and users usually feel distressed because they do not remember the replacement time; second, under freezing conditions, the filter will be damaged
