Sensor, sewage draining exit, blowdown valve and blowdown actuator composition, cylinder is pipe-like, and both ends are welded with end plate respectively, in two end plates
On along tubular axis be respectively equipped with inlet and outlet, and be installed with inlet pressure sensor in the connecting tube of water inlet,
Filter cylinder is installed on the intracorporal end plate of cylinder by connecting tube, the other end of filter cylinder is sealing plate, is laid on filter cylinder and sealing plate
Filter hole is installed with valve plate in filter cylinder at the end plate of water inlet, and valve plate is slightly fixed on valve shaft by fixation, valve plate
Axis passes through filter cylinder and is installed on cylinder, and backwash actuator is installed with outside cylinder, and sewage draining exit is located at cylinder body bottom, and passes through cylinder
Body is connected to through sewage pipe with filter cylinder, and communication port is located at filter cylinder at sealing plate, blowdown valve is installed on sewage draining exit, and arranging
Blowdown actuator is configured on dirty valve, outlet pressure sensor is installed on cylinder, inlet pressure sensor, backwash actuator,
Outlet pressure sensor and blowdown actuator are wired to controller respectively, and controller is fixed on cylinder.
When normal operation, backwash actuator control valves plate is opening state, and blowdown actuator control of sewage disposal valve is to close shape, water
Stream enters from the inlet filter cylinder and is flowed out after filter hole filters by water outlet, and the impurity in water flow is intercepted at filter cylinder
Interior, when the impurity intercepted in filter cylinder is more, controller detects the pressure value of inlet pressure sensor and outlet pressure sensor
It is compared, when its difference reaches set clean range, controller is automatically into sewage backwash state, at this point, instead
The closing of actuator control valves plate is washed, blowdown actuator control of sewage disposal valve is opened, in this way, water flow is forced after entering from the inlet filter cylinder
Cylinder is flowed to by the filter hole before valve plate, the water flow into cylinder backwashes filter cylinder by the filter hole after valve plate again, and by blowdown
Valve discharge, after continuous blowdown 30~90 seconds, valve plate, which is opened, to be resetted, and blowdown valve is automatically closed after continuing blowdown 10~30 seconds,
It is restored to normal operating condition.
The invention has the advantages that realizing Full-automatic backwash drain, operation using the pressure difference value of inlet and outlet
It is convenient for management, can be unattended, and filter area is big, structural volume is small, facilitates installation and high degree of automation.
