A water purification filter with rotatable screen

Abstract

The invention discloses a water filter with rotatable filter screens. The water filter comprises a cubic filter body, a front end cover, a rear end cover and a rotatable filter element. The front end cover and the rear end cover are hermetically connected with the front end and the rear end of the filter body respectively. The front end cover is provided with a water inlet. A water outlet pipeline is connected to the upper side of the filter body hermetically. A sewage discharger is hermetically connected to the lower side of the filter body. The water filter is provided with two filter screens; when one filter screen is blocked after long-term use, the other filter screen can work instead by rotating the filter element. The water filter has the advantages that due to the filtering mode, time for shutdown maintenance caused by filter screen blocking is saved during practical use, and the two filter screens can be replaced at a time during filter screen cleaning and replacing, so that maintainers do not need to replace the filter screens frequently, and service time of the filter can be prolonged after one-time filter screen replacement.

Description

Technical field: [0001] The invention belongs to the technical field of water purification equipment, in particular to a water purification filter with a rotatable filter screen. Background technique: [0002] With the increasingly serious environmental pollution and the strengthening of people's environmental awareness, the quality of water sources has become the focus of attention all over the world. It is now recognized that water filtration systems must not only protect machinery, but people as well. Therefore, the application scope of water source filtration is more and more extensive. The application of self-cleaning filters can improve the efficiency of heat exchange devices. With the shortage of water resources in our country, the rapid development of industry and the deterioration of the environment, higher requirements are put forward for the implementation of clean production. In areas with poor water quality, it is often necessary to perform preliminary water f...

AI Technical Summary

Problems solved by technology

In areas with poor water quality, it is often necessary to perform preliminary water filtration first, but the water purification filter will be blocked during long-term use. Frequent replacement of the filter screen inside the filter is not only time-consuming and laborious, but also In some emergency water situations, it is also inconvenient to disassemble and replace
