Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, 2, two filtration recoil, from removing contamination water fetching device, comprises the intake 1 being provided with filter running through dykes and dams, intake 1 is connected with intake pipe 9, intake pipe 9 is provided with recoil tube 5, intake pipe 9 with recoil tube 5 are also provided with recoil supercharging device.This intake 1 one-tenth is horn-like, and the less one end of opening diameter is arranged on dykes and dams inside.Described filter comprises coarse strainer 3 and fie screen 2, and one end place that intake 1 diameter is larger arranges coarse strainer 3, also arranges fie screen 2 in the middle position of intake 1.
Above-mentioned recoil supercharging device comprises the booster pump 4 and the motor operated valve 6 that recoils that are arranged on recoil tube 5, booster pump 4 is provided with the motor mated with it, also comprise electric controller and the water intaking motor operated valve 7 be arranged on intake pipe 9, this electric controller is connected with the motor of booster pump 4, recoil motor operated valve 6 and motor operated valve 7 of fetching water simultaneously, electric controller is also provided with the time relay and pressure switch 8.Described pressure switch 8 is arranged on intake pipe 9 or recoil tube 5, and before being positioned at water intaking motor operated valve 7 or recoil motor operated valve 6.Described recoil tube 5 is the arm of intake pipe 9, before this recoil tube 5 is arranged on position intake pipe 9 being arranged water intaking motor operated valve 7.
Two filtration recoil is from the working method of water fetching device of removing contamination, and working method comprises normal water-supply method and the back flush mode of certainly removing contamination, and the switching of its water-supply method and back flush mode judges also control realization by electric controller.
When normal water-supply method, keep water intaking motor operated valve often to open, simultaneously out of service the and recoil motor operated valve of booster motor cuts out.Current enter intake pipe by intake, foreign material in water are adsorbed on filter screen by the filtration of coarse strainer and fie screen, variation in water pressure in normal water intaking process in pressure switch Real-Time Monitoring intake pipe, when hydraulic pressure in intake pipe is lower than 0.3MPa, pressure switch is connected, and electric controller switches to the back flush mode from removing contamination.
When recoil is removed contamination, water intaking motor operated valve keeps cutting out, the motor operated valve that simultaneously recoils is opened, booster motor startup optimization, clear water enters from recoil tube, High-Pressure Water oppositely goes out intake from intake pipe, makes the foreign material on fie screen and coarse strainer depart from filter screen under the impact of current, thus plays the effect recoiling and remove contamination.Time relay gas device starts timing when switching, and in order to control the recoil time, when reaching 5 minutes when back flushing, electric controller switches to normal water-supply method again.
Water intaking motor operated valve remains one open-one close with recoil motor operated valve, well avoids the phenomenon of in use current generation crossfire.
According to above-described embodiment, just the utility model can be realized well.What deserves to be explained is; under prerequisite based on said structure design; for solving same technical problem; even if some making on the utility model are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the utility model, therefore it also should in protection domain of the present utility model.
