Description
Technical field
The utility model belongs to the improvement of water-saving irrigation with water filtering device, and particularly self-priming cleans well strainer.
Background technology
At present in the water-saving irrigation of progressively promoting, as sprinkling irrigation and drip irrigation, the water quality of irrigation water is required than higher, must be in advance filter out impurity and silt in the water, in case nozzle or drip irrigation zone obstruction by filter.The filter that tradition is used is well strainer, the well strainer and the well strainer that uses in parallel that have monomer to use.The well strainer that monomer uses stops up as filter screen occurring, when current are not smooth, stops to supply water, and manually cleans.Because of the needs filter quits work, the system that influences runs well.When the well strainer that uses in parallel needs to clean in the course of the work, can cut off a well strainer earlier and clean, the another well strainer carries out work.During in parallel the use,, can reduce the inflow-rate of water turbine of filter, reduce operating efficiency though can manually clean in turn.The artificial hourly water consumption that cleans greatly also needs to be equipped with the special messenger, causes the waste of water resource, and time-consuming.
Summary of the invention
The purpose of this utility model is to provide a kind of self-priming to clean well strainer, can realize automatic cleaning strainer, not need to be equipped with the special messenger, only need during cleaning seldom the water yield and lower hydraulic pressure, scavenging period is short, and does not influence the operate as normal of system when cleaning.
The purpose of this utility model is achieved in that a kind of self-priming cleans well strainer, comprise tank body that has water inlet and delivery port and the filter screen of in tank body, installing, the rear portion of water inlet is installed with circle tube leaching net by connecting ring in tank body, by bearing hollow shaft is installed in filter screen, uniform on hollow shaft the dirt sucking tube that the end has pollution-absorbing nozzle is being set, the openend of hollow shaft is installed on the support of connecting ring by bearing, stretch out the outer end of tank body with the stationary pipes of hollow shaft rotary seal magnetic valve is installed, the affixed power transmission shaft of hollow shaft blind end stretches out outside the tank body and matches with the reducing motor of supporting seat end, power transmission shaft is disposed with spiro rod section and guiding keyway section, wherein the nut that installs in spiro rod section and the supporting seat matches, guiding keyway section matches with the feather key of reducing motor rotor bore, both sides in supporting seat are installed with stop respectively, the contact disc of installing on the power transmission shaft of spiro rod section front side matches with stop, and pressure probe is installed respectively in the tank body of influent side and water outlet side.
Operation principle of the present utility model is: when press water enters from water inlet in the filter chamber of tank body filter screen, press water is discharged from delivery port behind strainer filtering.When a stage of filter work or enter water quality in the filter chamber when relatively poor, on the filter screen inwall, adhere to dirt more for a long time, the water yield through strainer filtering reduces, when making inside and outside chamber produce certain pressure reduction, differential pressure pickup starts, and drive reducing motor and magnetic valve is worked simultaneously by controller, reducing motor drives hollow shaft by power transmission shaft and rotates, pollution-absorbing nozzle on the hollow shaft on the uniform dirt sucking tube is inhaled the dirt that goes on the filter screen in pressing close to the filter screen rotation process, the water that to carry dirt under the effect of hydraulic pressure secretly enters hollow shaft, discharges through magnetic valve by hollow pipe.Reducing motor is in driving the power transmission shaft rotating process, the power transmission shaft spiro rod section matches with hold-down nut on the supporting seat, power transmission shaft is promoted forward, the guiding keyway section of power transmission shaft is under the constraint of the feather key of reducing motor rotor bore, in transmission,, the rotation limit, soil pick-up mouth of hollow dirt sucking tube is moved forward to front slide; When the contact disc of the power transmission shaft that moves forward in the transmission is run into the stop of front side in the supporting seat, the counter-rotating of controller control reducing motor, hold-down nut falls back power transmission shaft drive hollow shaft on supporting seat, when the contact disc on the power transmission shaft that falls back is run into the stop of rear side in the supporting seat, reducing motor just changes, automatic reciprocating periodic duty.When the dirt on the filter screen exhausted, when the pressure reduction in inside and outside chamber was tending towards close or equal, this moment, reducing motor quit work.The utility model cleans the working time and the intermittent time of filter screen and can set arbitrarily in 1200 minutes by the timing knob of time controller.The utility model is realized automatic cleaning strainer automaticity height, does not need to be equipped with the special messenger, only need during cleaning seldom the water yield and lower hydraulic pressure, scavenging period is short, and does not influence the operate as normal of system when cleaning.Filter is uninterrupted normal water supply when cleaning, and the self-cleaning time only needs 20-40 second, to not influence of normal water supply.The method of control can be diversification, and electric-control board can satisfy various requirement: controlled pressure reduction or time clean, also can continuous wash, and early warning signal can also be provided, and wash number is realized memory and other function.
