Description
Technical field
The present invention relates to a kind of water purification filter fields, more particularly, to a kind of universal backwash fore filter.
Background technique
It, will not with a large amount of micro- vapour impurity for ensuring to generate in pipeline after fore filter is typically mounted on water inlet line water meter
It causes harm to the human body.And fore filter plays positive protective effect to concealed pipe, tap, electric appliance etc..
The device separated currently used for solid content in fluid media (medium) and suspended matter is mainly well strainer.Filter device
Work principle of filter is that solid content, the suspended matter etc. in liquid to be filtered are trapped in the one of filter screen using filter screen retention technology
Side.So continuous filtering, solid content, suspended matter for being retained down etc. are more and more, and the rate of filtration is slower and slower, and to mistake
Filter fluid still continuously enters, and the filter opening effective filtration area of filter screen is smaller and smaller, thus filter screen is caused to block, and needs
Regular interruption filters and is cleaned or replaced to filter screen.
The defect of well strainer has: (1) replacing strainer can be such that filtering interrupts, and not only increase cost, but also reduce filtering
Efficiency；(2) it is equipped with back purge system, causes equipment investment and operating cost height, Operation and Maintenance complicated.In in view of the above-mentioned problems,
State's patent discloses " a kind of net formula fluid filtration method and device ", application number: CN201611179900.2, main technical schemes
Are as follows: include the following steps: that fluid to be filtered flows inwardly from the outside of the strainer with the surfaces of revolution；The impurity retained by strainer
It is attached on strainer or stays in outside strainer；Disturbance device outside strainer is set centered on the axis of strainer, opposed screen rotation
Turn；When disturbance device opposed screen is rotated with pre-set velocity, the disturbance part of disturbance device drives fluid rotation in circular motion
Turn, makes the impurity in fluid under the influence of centrifugal force far from strainer；Meanwhile when disturbance device rotation, in disturbance device and filter
Dynamic negative-pressure area is formed between net；Under the action of dynamic negative-pressure area, the impurity being attached on strainer is detached from strainer, realizes strainer
Cleaning；The fluid for flowing into strainer is flowed out from one end of strainer, realizes the filtering of fluid.Present invention aims at improve strainer
Cleaning effect improves filtering flow efficiency.The disclosure of above-mentioned patent, the impurity attachment for solving filter to a certain extent are asked
Topic.But our company engineer thinks, this is not optimal structure setting, and filter still has more preferably structure design to realize filter
Net cleaning problems.
Summary of the invention
