(5) specific embodiment

Embodiment: referring to Fig. 1, Fig. 2 and Fig. 3, a kind of water treatment filtration equipment comprises that pressure switch 32, five is to valve 10, magnetic valve 82, cylinder 41, control panel, water filter 31 and water pump 21;

Comprise relay 93, first timer 91 and second timer 92 in the control panel;

Pressure switch 32 is located at water filter 31 upper ends, be used to survey the hydraulic pressure of water filter 31 and the control circuit in the control panel joins, first timer, 91 controls, five motors to valve 10, the timing of second timer, 92 control magnetic valves, 82, the second timers 92 should be greater than the timing of first timer 91; In this example, 91 timing of first timer are three minutes, and 92 timing of second timer are four minutes.

In the cylinder 41 on the piston 42 the first gas circuit A of space and magnetic valve 82 communicate, the second gas circuit B of 42 times spaces of piston and magnetic valve 82 communicates in the cylinder 41;

Water pump 21 1 ends connect waste water tank 61, and the other end links to each other with five the 3rd valves 13 to valve 10 by pipeline;

Five first valves 11 to valve 10 link to each other with anti-wash tank 71, five communicate to second valve 12 of valve 10 and the lower end of water filter, five are located at the upper end of water filter to the 5th valve 15 of valve 10, five the 4th valves 14 to valve 10 link to each other with delivery port 52, and when the first gas circuit A of magnetic valve 82 opened, piston 42 stretched out, delivery port 52 and waste water tank 61 communicate, when the second gas circuit B of magnetic valve 82 opens, piston 42 withdrawals, delivery port 52 and filtered water tank 51 communicate;

When just washing, five to the 3rd valve 13 of valve 10 with the 5th valve 15 communicates and second valve 12 and the 4th valve 14 communicate, and first valve 11 is closed; When backwash, five to the 3rd valve 13 of valve 10 with second valve 12 communicates and the 5th valve 15 and first valve 11 communicate, and the 4th valve 14 is closed.

During backwash, cylinder 41 pistons 42 stretch out delivery port 52 are moved in the waste water tank 61, during filtration, treat the clear back of water (by time control), and 42 withdrawals of cylinder 41 pistons move to filtered water tank 51 with delivery port 52.

Occupation mode of the present utility model is: the line cutting wastewater flow in the waste water tank 61, is filtered into clear water by water filter 31, flows in the filtered water tank 51, and filtered water tank 51 and linear cutting equipment join, and promptly the water in the filtered water tank 51 is that linear cutting equipment is used.

The course of work of the present utility model is: add air voltage source, the gas circuit of air voltage source passes to magnetic valve 82, after the air voltage source starting, air-flow makes the second gas circuit B of magnetic valve 82 open (for original state), the first gas circuit A is closed condition, and piston 42 is moved toward cylinder bottom, and delivery port 52 and filtered water tank 51 communicate.

The starting panel Switching Power Supply, water pump 21 startings, first timer 91 and second timer 92 are worked simultaneously, five electrical powers to valve 10 (be three minute by the control of first timer 91 its conduction time), machine operation make five to the 3rd valve 13 of valve 10 with second valve 12 communicates and the 5th valve 15 and first valve 11 communicate, the 4th valve 14 is closed, carry out backwash, the water that backwash is come out flows in the anti-wash tank 71 by five first valves 11 to valve 10, and the backwash time is three minutes; Simultaneously, (its conduction time is by 92 controls of second timer in magnetic valve 82 energisings, it is four minutes), the first gas circuit A of magnetic valve 82 opens with the second gas circuit B and closes, the first gas circuit A that air communication is crossed magnetic valve 82 flows into piston 42 tops in the cylinder 41, piston 42 moves outward, delivery port 52 is moved to waste water tank 61, time is four minutes, here the bull point clock be for backwash the time remaining sewage discharge (remaining sewage discharge is to waste water tank 61 during backwash in waste water tank 61, after treating that water is clear, the process of getting back to filtered water tank 51 is for visiting the water process), first timer 91 quits work after three minutes, five motor outages to valve 10, restPose, five to the 3rd valve 13 of valve 10 with the 5th valve 15 communicates and second valve 12 and the 4th valve 14 communicate, and first valve 11 is closed; Filter, the water that instantaneous (one minute) filters out flows in the waste water tank 61, filters after one minute, second timer 92 quits work, the first gas circuit A is cut off in magnetic valve 82 outages, opens the second gas circuit B, piston 42 is moved toward the cylinder bottom direction, delivery port 52 is moved to filtered water tank 51, and clear water flows into filtered water tank 51, and it is used that the water in the filtered water tank 51 promptly can be the line cutting, the waste water that linear cutting equipment produces flows back in the waste water tank 61 and recycles environmental protection and energy saving like this.(delivery port 52 used pipelines are flexible pipe)

In filter process, filter impurity more for a long time in water filter 31, hydraulic pressure raises, discharge reduces, pressure switch 32 induction hydraulic pressure, when reaching setting hydraulic pressure, pressure switch 32 closures, in the relay 93 1 and 5 disconnected, entire circuit outage this moment, relay 93 recovers energising because of the dead electricity entire circuit that resets, and first timer 91 and second timer 92 restart timing, repeat above-mentioned backwash, filter and visit the water process, go round and begin again like this, repeat to filter (just washing), backwash and spy water, control automatically, replace loaded down with trivial details manually-operated, reduced operating cost.

In the utility model, the position of delivery port 52 can be controlled with rocker, and this also belongs to the claimed scope of the utility model.
