13, float 13, float and close air inlet and exhaust valve in the situation that having water, and when pressure release, float is opened, the effect of nearly gas.Float is the mode of injection molding, and float seal ethylene propylene diene rubber (EPDM) is for having corrosion resistant function
Filter process: the water inlet 2A of former water by base enters ring cavity 3A in filter element shell 3 through the 5A place, inside of filtering gap 4A between lamination 4 and enter filter core 5, now particle is intercepted at the outer surface of lamination 4, check valve 1 is opened simultaneously, water flows out by outlet 1A place, then reserves filter element through outlet 2B place.The side opening 7A that enters in addition water process diaphragm spindle 7 lower ends in filter element enters in the mesopore 7B of diaphragm spindle 7, then enters the epicoele 11A place of barrier film 9, and water enters in intake and exhaust valve gap 12 through float hole 12A again.When water is full of exhaust valve cap 12 when interior.Float 13 floats, and the float seat that float 13 lower ends connect is closed the passage of float hole 12A, and now barrier film 9 moves down under the effect of water pressure, and barrier film cavity of resorption 11B is communicated with outside air, and air is got rid of.Thereby it is downward to promote diaphragm spindle 7, thereby diaphragm spindle 7 promotes filter core gland 6 again, the downward lamination 4. that compresses makes former water enter in filter core 5 through the gap between the lamination 4 compressing. complete the process of same particulate separation.
Backwash process: water enters filter element from outlet 2B when needs backwash, now the delivery port 1A of check valve 1 closes, water enters in the scavenge pipe 5C in filter core by the mouth of pipe 1B of four pipe scavenge pipe 5C, at the row's aperture 5B by scavenge pipe 5C sidewall, along tangential jet, go out, to filtering lamination 4, rinse, one water of scavenge pipe 5C upper end upwards enters in the cavity of resorption 6A of filter core gland 6 in addition, now the water inlet 2A place due to filter element does not have pressure, so barrier film epicoele 11A place does not have pressure yet.And there is pressure at the cavity of resorption 6A place of filter core gland 6, this is to move on the effect lower filter gland 6 of pressure, on diaphragm spindle 7, moves, and on barrier film 9, moves.Owing to moving on filter core gland 6, unclamp disc 4.Disc is (from inside to outside) under the effect of tangent line current.Rotation is at a high speed got up, and its surperficial particle is rinsed well.The water cleaning is got rid of filter element through water inlet 2A.Now, because epicoele 11A place pressure is zero, float 13 falls under the effect of gravity, opens float hole 12A, by intake valve 12B air inlet, completes the process of backwash.
When needs backwash Time Controller sends hydraulic signal to backwash valve 07, make it from filtration condition, switch to backwash state.The filter element of now first backwash carries out backwash by clear water after the filter of other filter element through outlet pipe 02, and backwash sewage is discharged from through blow-off pipe 05.During due to backwash, filter element is communicated with blow-off pipe 05, and now filter element internal pressure is zero.In air-intaking exhaust valve, float is automatically opened under the effect of gravity, to the inner air inlet of filter element.
The backwash end time of first filter element is when arrive, controller stops adding to the water signal of first backwash valve, filtration condition is got back in backwash valve 07 switching, and filter element core gland compresses lamination again by hydraulic drives barrier film, and the filter element of first backwash is got back to again filtration condition.The 2nd backwash filter element and this system other filter element thereafter all passes through same working procedure, completes in turn backwash.At all filters, complete after backwash, system is got back to again inceptive filtering state (note: filter element quantity has 2.3.4.5 ... 24. can connect at most 24)
The above is preferred embodiment of the present utility model and the know-why used thereof; for a person skilled in the art; in the situation that not deviating from spirit and scope of the present utility model; the apparent changes such as any equivalent transformation based on technical solutions of the utility model basis, simple replacement, within all belonging to the utility model protection domain.
