INCorresponding opposite side, and (unidirectional) blowoff valve is installed; Described cylindrical shell 3 sealings equipped (by seal washer 4 and bolt 5) have cover 6, have backwash mouth B at the center of cover
IN, and backwash (unidirectional) valve 7 is installed; Described screen pack is the two-layer compound screen pack of detachable, fills out the lining nonwoven between the double-layer filtering net, and the base of composite filter net (by trip bolt 19) is fixed on the bottom of cylindrical shell 3, and the apical position of composite filter net is higher than described delivery port; Water inlet position in cylindrical shell 3 bottoms is equipped with active clapboard, active clapboard adopts hinge typed structure, its fixed page 16 (by dividing plate trip bolt 17) is packed in the bottom of cylindrical shell 3, fixed page 16 is connected with active page 11 by hinge connecting pin 18, and active page 11 serves as axle folding up and down with hinge connecting pin 18.Described cylindrical shell 3 embodiment adopt the quality carbon steel material.Described cover 6 embodiment adopt the compression-resistant structure design of arc.
Further feature of the present invention is, described blowoff valve by with the stainless steel taper bolt 13 of sewage draining exit inner cavity of pipe coupling, regulator bolts 15 machineries that the spring 14 of retaining pressure are provided and adjust spring pressure for the stainless steel taper bolt assemble.Rely on the potential energy of spring 14, stainless steel taper bolt 13 can be blocked sewage draining exit P
OUT, adjust the potential energy that regulator bolts 15 can change spring 14, also promptly changed pressure, and then changed required blowdown (counter-flushing liquid) pressure stainless steel taper bolt 13.
Of the present inventionly be further characterized in that described composite filter net adopts double-deck dome column type structure (referring to Fig. 1), internal layer screen pack 10 and outer filter net 8 are stainless steel filtering net, fill out lining nonwoven 9 between internal layer screen pack 10 and the outer filter net 8.The mesh diameter that described internal layer stainless steel filtering net 10 and outer stainless steel filtering net 8 embodiment adopt is 3.0 * 3.0mm
2Described nonwoven fill out the lining thickness be 1-5mm, the aperture embodiment of nonwoven adopts 100-200 μ m.Obviously, the aperture of the mesh diameter of described stainless steel filtering net and nonwoven and thickness all can require to select and be equipped with according to filtering.
Operation principle of the present invention and process are: when normal filtration, water intaking valve 1 is an opening, and outlet valve 12 is an opening, and backwash valve 7 is a closed condition; Regulate the pressure size of described regulator bolts 15 simultaneously, the opening pressure that makes described stainless steel taper bolt 13 is the fluid pressure in the cylindrical shell 3 during greater than normal filtration, thereby stainless steel taper bolt 13 is stably blocked sewage draining exit P when guaranteeing normal filtration
OUTOn the other hand, fluid pressure when the opening pressure of described stainless steel taper bolt 13 is less than backwash high pressure cleaning fluid, water under high pressure or other highly pressurised liquid (abbreviation counter-flushing liquid) that is suitable for injections in the cylindrical shell 3, stainless steel taper bolt 13 can be pushed open smoothly during with the assurance backwash, from sewage draining exit P
OUTEffluent sewerage.Filtered water stream is by water intaking valve 1 access to plant, its impulsive force will be opened the active page 11 of active clapboard, after the compound screen pack of described stainless steel (successively through internal layer stainless (steel) wire 10, nonwoven 9 and outer stainless (steel) wire 8) filters (fine particle impurity in the water and suspension precipitation or be trapped on the compound screen pack of stainless steel), again through outlet valve 7 from delivery port C
OUTDischarge.
When contamination precipitation in the device acquires a certain degree or after operative installations filters certain hour, makes water intaking valve 1 be closed condition by manual control, outlet valve is 12 closed conditions, and backwash valve 7 is an opening.Counter-flushing liquid is through the backwash mouth B of backwash valve 7 from resistance to compression cover 6
INEnter, the top of at first washing outer stainless steel filtering net 8 is also descending, enters between outer stainless steel filtering net 8 outsides and cylindrical shell 3 inwalls and washes, and the impurity that is attached on outer stainless steel filtering net 8 and cylindrical shell 3 inwalls is rinsed out; Because the impact force action of counter-flushing liquid, the active page 11 of described active clapboard is closed, the blocking-up water inlet A
IN, counter-flushing liquid will enter composite filter net from outer stainless steel filtering net 8, passes interlayer nonwoven 9 and internal layer stainless steel filtering net 10 successively, and the impurity that sticks on interlayer nonwoven 9 and the internal layer stainless steel filtering net 10 is rinsed out; When counter-flushing liquid pressure reaches certain value, will overcome the pressure of described spring 14, wash open and block described sewage draining exit P
OUTIn stainless steel taper bolt 13, impurity from sewage draining exit P
OUTDischarge smoothly, finish backwash.
Be the automation of device for carrying out said, further feature of the present invention is, this device also comprises automatic controls, and automatic controls is included in water inlet A
INWith the pressure sensor 2 that is connected between the lateral wall of cylindrical shell 3, pressure sensor 2 is connected with controller; And described water intaking valve 1, outlet valve 12 and backwash valve 7 are magnetic valve, described entering water electromagnetic valve, go out water solenoid valve and the backwash magnetic valve is controlled by controller.In the automatic controls that increases, described magnetic valve (unidirectional) is existing procucts, and all can be connected with peripheral control unit by the preferred circuit interface; Described pressure sensor 2 also is the commercially available prod; Described controller also is a prior art products.
Apparatus of the present invention are implemented backwash by automatic controls and are controlled automatically.Its operation principle and process are: when contamination precipitation in the device acquires a certain degree or after operative installations filters certain hour, the inside and outside force value of described composite filter net can produce certain pressure reduction, when this pressure differential reaches setting numerical value, described pressure sensor 2 will detect this pressure information, and the pressure sensor 2 output signals of telecommunication are to the controlling organization of automatic backwash device then; This controlling organization is a pumping signal with the signal of pressure sensor 2, closes described entering water electromagnetic valve and describedly goes out water solenoid valve, and open described backwash magnetic valve, introduce counter-flushing liquid, composite filter net and cylindrical shell 3 are carried out backwash, impurity is effectively rinsed out, and from described sewage draining exit P
OUTEffluent sewerage has solved the contamination precipitation problem in the device automatically.Surplus with described manual control procedure.
The present invention does not address part and is applicable to prior art.
