Description
Technical field
The present invention relates to a kind of sewage purification treatment facility, particularly relate to a kind of differential filter automatic flushing sewage purifying device.
Background technology
At present, at home on the water treatment market, be flooded with " automatic backwash " differential filter (also claiming self-cleaning filter) of numerous brands, no matter be import or homemade, they are similar on process structure, meet filter screen adhesion impurity firm or that be jammed in the filter screen passage and but can't remove, and accumulate over a long period, finally make filter screen lose water permeable ability, influence the service life of filter screen.Just because of the limitation of this cleaning way, make the filtering accuracy of these products to do more, the ideal that the high accuracy of being declared also just can't realize.Existing differential filter comprises base, be installed in the body on the base, driving mechanism and electrical control mechanism, wherein body is formed by mixing district and filtering area, mix and distinguish the agitating device that comprises drive mechanism, auxiliary agent filler and original water inlet, filtering area comprises filter mechanism, slag-drip opening, pure water inlet and backwash mechanism.
Summary of the invention
The object of the invention is to overcome the above-mentioned defective of prior art, and a kind of filtering accuracy height is provided, and screen pack can not stop up the differential filter automatic flushing sewage purifying device of long service life.
For achieving the above object, differential filter automatic flushing sewage purifying device of the present invention comprises base, raw water pump, be installed in the body on the base, driving mechanism and electrical control mechanism, wherein body is formed by mixing district and filtering area, mix and distinguish the agitating device that comprises drive mechanism, auxiliary agent filler and original water inlet, filtering area comprises filter mechanism, connects slagging device and the pure water inlet and the backwash mechanism of sewage draining exit; Its special feature is that filter mechanism comprises coarse strainer and differential smart filter screen, and backwash mechanism is fitted in the differential smart filter screen outside, and pressure transmitter all is equipped with in the filter mechanism both sides, and pressure transmitter connects backwash mechanism by electrical control mechanism.So design, when the pressure reduction of two pressure transmitters surpasses setting value, electrical control mechanism will start the dirt that backwash mechanism clears up differential smart filter screen inboard, when the pressure reduction of two pressure transmitters drops to setting value, will stop backwash mechanism, thereby keep the long-term operate as normal of smart filter screen automatically; Smart filter screen precision can in time obtain cleaning because be blocked in the dirt of smart filter screen inboard, can not influence service life and normal the use, so can require to improve as much as possible according to purifying.It has the filtering accuracy height, and screen pack can not stop up the advantage of long service life.
As optimization, differential smart filter screen inboard also is furnished with the contaminants collector that suction nozzle is housed, and contaminants collector connects electrical control mechanism; Electrical control mechanism is equipped with by the pressure reduction startup of two pressure transmitters and the control slagging device of closing, the synchronization control circuit that backwash mechanism and contaminants collector turn round simultaneously.The introducing that the contaminants collector of suction nozzle is housed can improve the dirt cleaning efficiency, reduces the cleaning amount.
As optimization, synchronization control circuit is the control raw water pump, agitating device, slagging device, the control circuit that backwash mechanism and contaminants collector turn round simultaneously.Can clear up, purify and carry out simultaneously.
As optimization, contaminants collector also is furnished with the suction nozzle driving mechanism of supporting suction nozzle rotation and horizontal reciprocating movement.Can improve the dirt cleaning efficiency greatly.
As optimization, differential smart filter screen is a stainless steel sintering net, and backwash mechanism comprises drive motors and backwash high pressure pump.The former filter screen mechanical strength is big, the convenient recycling flushing water of the latter.
As optimization, differential smart filter screen is a 316L type stainless steel sintering net, and what the auxiliary agent filler was annotated is flocculant.The former filtering accuracy height, the latter can significantly improve filter effect.
Its course of work is:
At first with the external pressure mode coarse strainer of flowing through, filtering larger particles impurity.The coarse strainer water outlet enters smart filter screen with inner pressed, and further the fine impurities in the trap water is sent to by delivery port at last and uses water spot.Along with the accumulation of all contaminations in the filter medium in smart filter screen inboard, filtration channel is blocked, water inlet pressure reduction increases gradually, when pressure reduction reaches predetermined value, the pressure difference transmitter that is connected in water inlet just converts this detection signal to the signal of telecommunication, pass to electrical control mechanism, thereby start drive motors and backwash high pressure pump simultaneously, start the contaminants collector that suction nozzle is housed this moment and do rotation and horizontal back and forth movement in the filter screen inboard, simultaneously, in the filter screen outside, backwash mechanism and blowdown mechanism synchronization action, and be corresponding relation, under the prerequisite of not interrupting normal operation, only by sub-fraction water, filter screen is carried out the high pressure backwash, and backwash water sees through filter screen, is sucked contaminants collector rapidly together with the impurity of peeling off from filter screen, deliver to slagging device, discharged by sewage draining exit at last, behind the backwash stroke, pressure reduction reduces, each parts resets, and system reenters normal operating condition.
Effect: the pressure reduction net adopts 316L stainless steel sintering net, makes mechanical strength and filtering accuracy that reliable assurance arranged, and by heterodyne in the filter screen, high filtering precision can reach 2 microns.
After adopting technique scheme, differential filter automatic flushing sewage purifying device of the present invention has the filtering accuracy height, and screen pack can not stop up long service life, the advantage that very suitable purification of paper-making effluent is handled.
