Specific embodiment
The present invention will be further explained below.
Self-cleaning filter of the invention includes shell, water inlet, top cover, clear water output, filter, in addition, further including
Self-cleaning system, the Self-cleaning system include pressure gauge, waterpower cylinder, pressure difference switch, electric controller, blowdown valve, sewage pipe, waterpower
Motor chamber.The cylinder is fixedly arranged on the top cover, and the filter is installed in the shell, and the winding arrangement of strainer is vertical
To winding, and filter side and bottom are respectively arranged with water inlet and sewage draining exit, and the blowdown valve is set to the filter
It is interior, it is in close contact with filter inner wall, the center of blowdown valve is connect with the piston rod of the waterpower cylinder, and the two of the pressure difference switch
End is separately positioned at the entery and delivery port of the shell, and is connect with electric controller, the electric controller and waterpower cylinder, pressure difference switch
It is connected with electric blowdown valve by control signal wire.
Filter includes coarse filtration core assembly and fie screen.
Its internal structure of self-cleaning filter is that 304 stainless steel blowdown valves and 316L stainless steel filtering net and driving member form,
Cleaning blowdown is automatically performed by driving motor and motor-driven valve, mode of operation is automatic running (can also run manually), has pressure difference
Or timing automatic blowdown function.Filter uses the hydraulic principle of low in and high out, and water flow is entered by bottom water inlet, works as water flow
When by filter, mechanical admixture fine particle and silt particle in water are intercepted by filter screen, when the impurity of screen surface accumulation increases
