Operation principle of the present utility model is: water is entered by water inlet pipe, arrives screen pack.In filter process, screen pack builds up foul, the impurity in the water, forms the impurity screening layer, because impurity layer is deposited in the inboard of screen pack, has therefore just formed a pressure reduction in the inside and outside both sides of screen pack.Carry out automatic backwash by pressure difference switch, also can set timing automatic backwash according to water quality.
The utility model specific works process is:
The irrigation process, the first electromotive intake valve and the second electromotive intake valve are opened, and the first electronic blowoff valve and the second electronic blowoff valve are closed, during work water from water inlet pipe through two electromotive intake valve to two screen packs, to tank body, discharge from outlet pipe after filtering, irrigate.
The automatic backwash process:
1, the first screen pack is irrigated, washed the second screen pack: water is entered by water inlet pipe, arrives tank body through the first electromotive intake valve after the first screen pack filters.Most of water is discharged from outlet pipe and is irrigated, small part water second screen pack that recoils, foreign material in the second screen pack are discharged from blow-off pipe through the second electronic blowoff valve, and the first electromotive intake valve and the second electronic blowoff valve are for opening at this moment, and the second electromotive intake valve and the first electronic blowoff valve are for closing.
2, as a same reason, can realize that the second screen pack is irrigated, flushing the first screen pack: water is entered by water inlet pipe, arrives tank body through the second electromotive intake valve after the second screen pack filters.Most of water is discharged from outlet pipe and is irrigated, small part water first screen pack that recoils, foreign material in the first screen pack are discharged from blow-off pipe through the first electronic blowoff valve, and the second electromotive intake valve and the first electronic blowoff valve are for opening at this moment, and the first electromotive intake valve and the second electronic blowoff valve are for closing.
Two net backwashes can be got back to the normal irrigation duty after finishing.
The two net pressure reduction of the utility model utilization carry out backwash, can irrigate continuously the i.e. automatically anti-cleaning while irrigating.Compared with prior art, have the function of former water being filtered and automatically screen pack being cleaned blowdown, and system irrigates uninterruptedly when cleaning blowdown.
The utility model compared with prior art has the automaticity height, and treating capacity is large, but self-cleaning blowdown intermittently irrigate not, the advantage such as cleaning performance is better automatically, and application surface is extensive.
