Water purifier and ultrafiltration membrane unit thereof

Abstract

The invention discloses a water purifier and a ultrafiltration membrane unit thereof. The water purifier comprises a main box body, wherein a shell assembly is fixedly installed on one side of an inner cavity of the main box body, a first box body is slidably installed in an inner cavity of the shell assembly, a cleaning assembly is fixedly installed on the back face of the bottom of an inner cavity of the first box body, and the top of the cleaning assembly communicates with a water purification assembly. When the first electromagnetic valve is closed and the ultrasonic cleaning instrument is started, according to the principle of the ultrasonic cleaning instrument, a high-frequency oscillation signal sent by an ultrasonic generator is converted into high-frequency mechanical oscillation through a transducer and is spread into a cleaning solvent, and ultrasonic waves radiate forwards in a sparse and dense alternate mode in cleaning liquid; when the group particles are wrapped by oil dirt and adhered to the surface of a cleaning piece, oil is emulsified, solid particles are separated, and therefore the purpose of cleaning the cleaning piece is achieved, impurities obtained after cleaning are blended into water and enter a cleaning bin of the ultrasonic cleaning instrument, and meanwhile the capillary type ultrafiltration membrane is dredged.

Description

technical field [0001] The invention relates to the technical field of water purifier equipment, in particular to a water purifier and an ultrafiltration membrane unit thereof. Background technique [0002] Water purifiers are also called water purifiers and water quality purifiers. They are water treatment equipment that perform in-depth filtration and purification of water quality according to the requirements for water use. The water purifiers we usually refer to generally refer to small Purifiers, ultrafiltration machines are equipment that use ultrafiltration technology to purify water. The difference from other water purification equipment is that they use ultrafiltration membranes. Ultrafiltration membranes have the same pore size and the rated pore size range is 0.01-0.001 Micron microporous filtration membrane, using ultrafiltration membrane The membrane filtration method driven by pressure difference is ultrafiltration membrane filtration, a microporous filtration ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a water purifier and its ultrafiltration membrane unit, which has the advantage of automatic cleaning and sewage discharge, and solves the problem that when the existing water purifier is in use, most of them use dead filtration to filter the water body. The ultrafiltration membrane filter element will be full of impurities and difficult to discharge, which will reduce the filtering effect and may cause poor water flow. It is necessary to disassemble the ultrafiltration membrane element from the water purifier for replacement or cleaning, which is very inconvenient and non-professional Difficult to operate
