Above-mentioned self-cleaning flings well strainer, and described sewage draining exit is a circular hole;
Above-mentioned self-cleaning flings well strainer, and described sewage draining exit can be funnel-form, helps impurity like this and passes through;
Above-mentioned self-cleaning flings well strainer, and described water inlet pipe is coaxial with described guiding device;
Above-mentioned self-cleaning flings well strainer, and described outlet pipe is vertical mutually with described guiding device;
Above-mentioned self-cleaning flings well strainer, is provided with inner seal ring between described filter screen and the tank body;
Above-mentioned self-cleaning flings well strainer, is provided with exterior seal ring between described tank body main body and the top cover.
Current enter from water inlet pipe, the guiding device of flowing through, because the effect of guiding device, water velocity in the runner increases and forms turbulent flow, the fast flow speed and direction of current that is turbulent flings bottom, wash road, also fast to the settling zone deposition that flings bottom, wash road, impurity is short in the time that screen surface stops, and is difficult for stopping up filter screen for impurity in the current; The current that are turbulent also constantly contact with filter screen from all directions, increase the area that current contact with screen surface, good filtration effect; Be the impurity on the flushing filter screen of the continuous multi-angle of current of turbulent, impurity is not easy attached on the filter screen, directly is flushed to blow-off pipe, and the drain tank external body has realized the effect of automatic cleaning then.
The beneficial effects of the utility model are: simple in structure, easy to operate, cost is low; Filter screen inside is provided with guiding device, makes current form turbulent flow, good filtration effect; Can clean filter screen automatically, filter screen is difficult for stopping up long service life; Tank body is provided with dismountable top cover, and is easy to maintenance.
