Description
Technical field
The utility model relates to a kind of filter, especially a kind of self-priming backwash net-type filter.
Background technology
Along with the rise of water-saving agriculture, the drip irrigation and spray irrigation technology is just used more and more widely, and used filter can not adapt with it in the drip irrigation and spray irrigation at present, and common filter has three kinds at present: centrifugal, sandstone formula, net formula or stacked.
Centrifugal type filter is usually used in the size particles separation and dust is handled.Along with the rotation of water, the bulky grain centrifugal force in the water is bigger, along the edge rotation, reaches centrifugation.How particle, be the key of problem in husky jar of the income collection with certain kinetic energy.Traditional exocentric structure can make the effect of a part of particle rotation with gravity, enters husky jar of collection, and another part diminishes because of the bottom eck, and speed strengthens, and particle is kicked up once more, enters delivery port, has influenced filter effect.
Sandrock filter is usually used in pure water to be handled, and utilizes aggregate grading to form a 3 D stereo filter core, when current through out-of-date, the particle suction reaches the filtration purpose on the sandstone surface in the water.If water quality inferiority or service time are long, the loss of flood peak is excessive, if aggregate grading is improper, pressure reduction is increased or poor filtration effect, also has not easy cleaning in addition, cost height, bulky shortcoming.
Well strainer (or stacked) has simple in structure, the advantage that make, use cost is low, especially can dispose the filter screen in different apertures according to actual needs arbitrarily and realize different filtration needs, but because of present well strainer unreasonable structure, silt needs manual cleanup, and adsorption capacity is poor, with increasing of screen cloth adsorbent particles, pressure reduction (loss of flood peak) strengthens, so that loses strainability.
Technology contents
The purpose of this utility model provides a kind of simple in structure, and convenient operation and management can be taken the self-priming backwash net-type filter that filter can clean filter screen automatically apart.
The utility model comprises filter housings, water inlet pipe, outlet pipe and sewage draining exit, it is characterized in that being provided with in the filter housings filter chamber that a tubular screen pack constitutes, the hollow shaft that blow-off pipe is arranged in the middle of being provided with in the filter chamber, be provided with a blowdown chamber that isolates with screen pack in the filter housings before the sewage draining exit, the other end of described hollow shaft stretches in the blowdown chamber, be provided with several suction nozzles on one section hollow shaft in the filter chamber, the suction nozzle of suction nozzle is pressed close to the screen pack wall, the suction pipe of suction nozzle is connected with the blow-off pipe of hollow shaft, be provided with water jets on one section hollow shaft in the blowdown chamber, this water jets is at least two, equidistantly be connected on the hollow shaft by spray boom, the outlet of water jets is towards the tangential direction of axle, at sewage draining exit, be equipped with valve on water inlet pipe and the outlet pipe.
Water inlet in the filter chamber that above-mentioned tubular screen pack constitutes preferably is provided with the one-level screen pack, above-mentioned filter chamber is divided into one-level filter chamber and cascade filtration chamber, and one-level screen pack mesh is greater than tubular screen pack mesh.
Above-mentioned filter preferably is provided with blowdown and cleans automaton, comprises controller, pressure detecting head, and the valve at described sewage draining exit, water inlet pipe, outlet pipe place is a magnetic valve.
The utility model course of work is as follows: when water enters the one-level filter chamber by water inlet, some floating things, large granular impurities etc. are blocked by the one-level screen pack, after water enters the cascade filtration chamber, more tiny silt is attracted to tubular and filters on the wire side, when silt amasss to a certain degree, the pressure reduction of water inlet and delivery port increases, open valve this moment at sewage draining exit, the blowdown cavity pressure descends, water in the filter chamber is through suction nozzle, hollow shaft, shower nozzle pours in the blowdown chamber, the cataract action of water jets outlet makes the hollow shaft rotation, drives the suction nozzle rotation simultaneously, draws silt and impurity that tubular filters wire side.
Clean automaton if be provided with blowdown, then establish the pressure detecting head at the water inlet pipe and the outlet pipe place of filter, at least establish magnetic valve at the sewage draining exit place, when the pressure reduction of water inlet and delivery port increases to a certain degree, controller promptly sends signal, opens the magnetic valve blowdown, when the pressure reduction of water inlet and delivery port is reduced to certain value or behind the certain hour, closed electromagnetic valve, blowdown finishes.
The utility model is simple in structure, and the management of blowdown cleaning operation is simple and convenient, and filth-discharging effect is good, can take filter apart and can clean filter screen automatically.
