Self-cleaning spray gun is installed between piece, the self-cleaning spray gun uses gradual change overflow section, area of passage constantly to reduce, it is described from
The head piece that enters of cleaning spray gun is equipped with strainer；Check-valves, the center of the Multi-layer annular lamination are installed at the sewage draining exit
Circular ring shape lamination inner cavity is formed, is surrounded in cabinet between the outside of the Multi-layer annular lamination and the inner wall and rack of cabinet
Chamber.
The positive and negative of the circular ring shape lamination is all machined with radiation connected in star, and the radiation connected in star is all along a direction
Radiation, the radiation connected in star of adjacent two blocks of circular ring shape laminations are staggered.
The area of passage of the self-cleaning spray gun is 4 by the area of passage ratio of entrance to outlet:2.5:1.
The import inclination angle of the self-cleaning spray gun is 30 degree.
The sewage draining exit is in 60 degree of angles with horizontal line, and the check-valves is tightly attached to sewage draining exit, can be under differential pressure action
It opens and closes.
The self-cleaning spray gun, cabinet, floor and rack are molded using integrated die-casting, using aluminum alloy material.
The circular ring shape lamination is made of three type polypropylene materials.
The check-valves is made of rubber material.
Using the cleaning method of any one self-cleaning filter, it includes the following steps：
1）Flow is entered by self-cleaning spray gun inside the Multi-layer annular lamination of cabinet inside, and circular ring shape lamination is passed through
Radiation connected in star filtering, the clear water after filtering enters cabinet inner cavity, and enters pump chamber by pump inlet pipeline；
2）The impurity filtered out is constantly rushed in sewage draining exit by the water that filter inlet enters by Multi-layer annular lamination, from clearly
It washes spray gun and utilizes bernoulli principle, by reducing flow section, constantly increase fluid flow rate, table in circular ring shape lamination will be attached to
The impurity in face is washed away into sewage draining exit；
3）Check-valves at sewage draining exit is since its own gravity is fitted tightly over sewage draining exit, since impurity is constantly deposited in blowdown
Mouthful so that since check-valves both sides form larger pressure difference, check-valves is opened, and impurity discharge, pressure difference reduces, closure of check ring,
Realize the self-cleaning of filter itself.
Compared with prior art, the beneficial effects of the invention are as follows：
1, of the invention self-cleaning spray gun, cabinet, floor and rack be using integrated die-casting molding, using aluminum alloy material,
Using above-mentioned simplified manufacturing process technical process, cost is reduced, and ensure that quality, is processed convenient for mass,
And it is simple in structure.
2, self-cleaning spray gun uses tapered cylindrical sleeve, using bernoulli principle, by reducing flow section, constantly
Increase fluid flow rate, the impurity for being attached to circular ring shape lamination inner surface is washed away into sewage draining exit.
3, by using Multi-layer annular lamination, and all processing radiation connected in star in the both ends of the surface of circular ring shape lamination can
It is effective to increase filter area, enhance filter efficiency.
4, circular ring shape lamination material be three type polypropylene, this material have high temperature resistant, it is anticorrosive, it is low temperature resistant the advantages that in turn
Improve the service life of filter.
5, by using Multi-layer annular lamination, and radiation shape is staggered adjacent two lamination clockwise, counterclockwise, adds
Big filter area enhances filter efficiency.
