Some backwash filters are also arranged in the market, but mainly be to wash by reverse flow, developing result is limited.
Particularly present backwash filter all needs to use electric power or external impetus to carry out driving work, and just can not normally use under away from the situation of power supply.
Summary of the invention
The purpose of this utility model is to provide a kind of backwash effect good, particularly can be in the self-priming backwash net-type filter mistake that does not have to use under civil power or the powered attendant-controlled wheelchairs situation.
The utility model comprises filter housing (2), water inlet (16), delivery port (6), backwash delivery port (12), described water inlet (16), delivery port (6) and backwash delivery port (12) locate to be equipped with valve (15), being provided with cylindrical net formula between water inlet (16) and delivery port (6) crosses filter core (3) cavity in the filter housing (2) is divided into two chambers, be soil chamber (13) and water-purifying cavity (14), water inlet (16) is located and water-purifying cavity (14) is equipped with pressure gauge (1), it is characterized in that: the net formula is crossed filter core (3) inboard and is axially arranged with anti-cleaning axle (5), should instead clean axle (5) is a hollow tubular, be provided with several backwash suction nozzles (4) at anti-axle (5) axis body that cleans, and the suction inlet of described backwash suction nozzle (4) is the narrow slit of an axial elongated rectangular shape, suction inlet is pressed close to the net formula and is crossed filter core (3) inwall, be provided with backwash actuator chamber (8) between soil chamber (13) and the backwash delivery port (12), a described anti-end that cleans axle (5) is communicated in the backwash actuator chamber (8), and the anti-axle (5) that cleans is provided with at least two water spray driving tubes (7) radially, the end of water spray driving tube (7) is provided with the nozzle of bending-like, simultaneously, the described anti-end of cleaning axle (5) also is provided with and reaches the outer pull bar (11) of filter housing (2).
As improvement, above-mentioned net formula is crossed the filter core front portion and preferably is provided with prefiltration net (17), and this prefiltration net (17) is kept apart soil chamber (13) and water inlet (16), and the mesh of prefiltration net (17) is crossed the mesh of filter core (3) greater than the net formula.
As further improvement, above-mentioned pull bar (11) preferably is provided with driving mechanism, and described driving mechanism is preferably hydraulic mechanism or the pneumatic mechanism that is made of piston (9) and piston cylinder (10).
The utility model course of work: the muddy water of irrigation enters filter by water inlet, crossing filter core 3 by cylindrical net formula filters, water purification after the filtration flows out from delivery port 6, impurity is blocked in the inboard that the net formula is crossed filter core 3 in the water, when impurity more for a long time, the net formula cross filter core 3 in, the outer pressure reduction that forms, when the pressure reduction of pressure gauge 1 demonstration reaches certain value, the valve that can open backwash delivery port 12 places carries out backsurging operation, because the effect of hydraulic pressure, current enter from the anti-backwash suction nozzle 4 that cleans on the axle 5 and instead clean the axle 5 and spray from the nozzle of the bending-like of water spray driving tube 7, water spray driving tube 7 produces the anti-axle 5 that cleans of thrust promotion and rotates, backwash suction nozzle 4 siphons away at the impurity of also the net formula being crossed simultaneously filter core 3 inboards with anti-cleaning axle 5 rotations, this moment pulling is anti-clean on the axle 5 pull bar 11, the impurity that side can be crossed whole net formula filter core 3 inboards inhale remove clean.
Compared with prior art, dependable performance of the present utility model, operational administrative is simple and convenient, and sewage backwash is effective, particularly can not have under civil power or the powered attendant-controlled wheelchairs situation, can normally use as long as have certain hydraulic pressure.
