The hollow main shaft two ends are supported on the filter tank by bearing, drive unit is that chain passes device, at axle head driven sprocket is installed, be provided with reducing motor at the top, filter tank, be fixed with drive sprocket on the reducing motor axle, be provided with driving-chain between drive sprocket and the driven sprocket, the sealing of hollow main shaft one end, the other end is uncovered as the filtered water delivery port, and the back suction sucker is installed on the sidewall of filter tank by fixed mount, and the back suction sucker links to each other with suction channel by flexible pipe.
The back suction sucker is the groove that is cuboid, and the groove of this cuboid is provided with along the filter disc radial direction, and it is provided with suction inlet and the filter medium outer surface is fitted.
The utility model is compared with prior art, and its effect is actively with tangible.Be provided with in this disk filter with the back suction of filter disc relative motion and inhale device, make back suction inhale device and filter disc relative motion, can clear up the residue in the filter disc outside like this by drive unit; Suction pipe is set in filter tank bottom the mud of bottom, filter tank is regularly aspirated, this two covering device the filter effect that can keep this filtration system good is set.And in this filtration system, also be provided with liquid level sensor and controller, because mud is stored in Chi Dihui the water level in the pond is risen, therefore this liquid level sensor can detect the amount retained of mud in the pond, obtain the signal of hydrostatic sensor by controller, and then back suction sucking pump, anti-suction valve, mud valve and drive unit controlled, realize clearing up automatically this filtration system.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, for the clear relative position relation that shows, back suction device, mud discharging device and liquid level sensor do not draw in Fig. 1.In the present embodiment, this sewage disposal system comprises filter tank 1 and filter, filter tank 1 is provided with water inlet 2 and water purification delivery port 3, also comprise a plurality of filter discs 4 that are arranged in parallel in this disk filter, back suction is inhaled device and mud discharging device, filter disc 4 is the hollow disc shape, this filter disc 4 is fixed on the rotary main shaft 10, rotary main shaft 10 is hollow form, the inner chamber of filter disc 4 and rotary main shaft 10 intracavity inter-connections, rotary main shaft 10 two ends are supported on the filter tank by bearing, drive unit is that chain passes device, rotary main shaft 10 1 ends are fixed with driven sprocket 111, be provided with motor 113 at the top, filter tank, be fixed with drive sprocket 112 on 113 on the motor, be provided with driving-chain 114 between drive sprocket 112 and the driven sprocket 111, rotary main shaft 10 other ends are offered filtered water delivery port 105, each filter disc 4 both sides is provided with a back suction sucker 81, back suction sucker 81 is the grooves that are cuboid, this rectangle cell body is provided with along the filter disc radial direction, back suction sucker 81 is connected with the filter tank sidewall by fixed mount 85, back suction sucker 81 links to each other with suction tube 82 by flexible pipe, suction tube 82 links to each other with back suction sucking pump 83, back suction suction pipe 82 is provided with anti-suction valve 84, anti-suction valve 84 is electrical ball valves, and mud discharging device comprises the suction pipe 91 of being located at the bottom, filter tank, and this suction pipe 91 is communicated with back suction sucking pump 83 by pipeline 92, this pipeline 92 is provided with mud valve, and mud valve is an electrical ball valve.
