Description
Technical field
The present invention relates to a kind of quartz filter, be specifically related to a kind of quartz filter with counter-flush.
Background technology
Present stage, water treatment more and more comes into one's own, because the quality of the quality of water is no matter be to producing or dayNormal life all can bring greater impact, and its impact all needs just can manifest after after a while mostly,The problem of water quality mostly can only be by the time except problem just can be pinpointed the problems in other words. Existing water filterMostly need to first pass through multi-medium filtering, and the multiplex quartz sand of the medium of more medium filter. Quartz sand filtrationBenefit is that filter effect is good, is convenient to backwash. But existing filter in use, be substantially all by stoneEnglish sands flat and is laid in the container of a bottom with screen pack, intake by top, due to water enter filter all withCertain pressure, and under Action of Gravity Field, water can be washed quartz sand open, goes out the few current of sand content and leads toRoad, thus cause a large amount of water through the filtration of quartz sand, to greatly reduce filter effect. And quartz sandFilter effect and water and quartz sand time of contact and area are directly proportional. Existing quartz filter, is difficult to ensureFully contacting of water and quartz sand, causes follow-up water treatment to bring larger pressure, and especially follow-up use is anti-When permeable membrane filters, can significantly increase the water consumption of reverse osmosis membrane backwash.
Summary of the invention
The object of this invention is to provide a kind of backwashing function with air water combination and can fully improve water andThe quartz filter of quartz sand time of contact.
For achieving the above object, the present invention includes a kind of quartz filter, it is characterized in that, comprise a ringShape shell, described circular casing becomes uniform eight fan rings by eight vertical barrier partitions; The external arc of each fan ringOuter surface is provided with water inlet; Set gradually in water inlet inner side the curved screen that four radiuses reduce step by step, by halfThe curved screen of footpath maximum, to the curved screen of radius minimum, is all filled with quartz sand between every two curved screens;The hollow parts that the curved screen of eight radius minimums surrounds circular casing forms filter pipe; Described filter pipe center byRiser is divided into symmetrical two parts, and the two ends of this riser respectively with two symmetrical vertical baffle plates same flatIn face;
The bottom of described filter pipe is communicated with a water supply box, water supply He center comprise one with the caliber phase of filter pipeSame cylindrical the first cavity, the top of cylindrical cavity in described water supply box and the bottom end seal of filter pipe connectConnect, this first cavity is separated by second riser parallel with riser, along the bottom of this second riser by firstThe bottom surface of cavity is divided into symmetrical two parts, and this two-part opening and closing is respectively by switch at the bottom of the first water cavityWith switch control at the bottom of the second water cavity, the both sides that described the first cavity is positioned at the second riser have water inlet, and water inletThe switching of mouth is by the first water cavity side switch and the second water cavity side switch control;
An air feed box is fixed in the lower end of described water supply box, and there are cylindrical second cavity, institute in this air feed He centerThe top of stating the cylindrical cavity in air feed box is connected with the bottom end seal of water supply box the first cavity, this second cavitySeparated by the 3rd riser parallel with riser, along the bottom of the 3rd riser, the bottom surface of the second cavity is divided intoSymmetrical two parts, and this two-part opening and closing is respectively by opening at the bottom of switch at the bottom of the first air cavity and the second air cavityClose and control, the both sides that described the second cavity is positioned at the 3rd riser have air inlet, and the switching of air inlet is by firstAir cavity side switch and the second air cavity side switch control.
Preferably, the lower inner surface of described circular casing is provided with a fan shape baffle near radial position place of water inlet,The upper end of this ring baffle does not contact with the upper inside surface of circular casing. This fan shape baffle can make into water more even.
Preferably, in described curved screen by the maximum curved screen of radius adjacent to the curved screen of radius minimumTwo screen clothes between be provided with one end and be fixed on the inner surface of circular casing bottom side the other end to the less sieve of radiusThe deflector that the oblique upper of the direction of net tilts, and the acclivitous one end of this deflector fixes a vertical deflector,The upper end of this vertical deflector does not contact with the inner surface of circular casing upside.
Further, also comprise a tank body, the excircle inner surface sealing solid and tank body of described annular outer cover connectsConnect, described tank body is provided with the water inlet pipe corresponding with water inlet.
Further, described circular casing has more than two, and described tank body is provided with the water inlet pipe corresponding with water inlet;And the part between the filter pipe of lower floor's circular casing of the filter pipe of the circular casing on upper strata and next-door neighbour is positioned at riser twoOn the tube wall of side, respectively have a through hole, these two through holes are respectively by the first filter pipe switch or the second filter pipe switchControl open and-shut mode.
Be set to eight fan rings uniformly by circular casing, filter process can be divided into eight unit simultaneously carry out,Greatly increase the uniformity of water filtration. And can use eight fan rings to filter by the control of water inlet simultaneously,Also can be only filter by four fan rings of riser one side, now on the screen pipe between two circular casingsThe first or second one of filter pipe switch open, and this switch with filter four fan rings be in riser withOne side. So can make the water filtering flow into down the water inlet of one deck circular casing one side by screen pipe. And position simultaneouslyAt the bottom of switch and the first or second air cavity at the bottom of the first or second water cavity of this side, switch is opened simultaneously, makes filtered waterCan flow out. And then make do not have water to pass through in the circular casing of a side of not carrying out drainage. Now can ring will be positioned atThe water supply box of shape shell lower end is positioned at the first or second water cavity side switch opens of riser opposite side, make current from down toOn pass into circular casing, and carry out backwash. In this process, also can will survey and open with the first or second opened water cavityPass be positioned at the bottom of first or second water cavity of the same side at the bottom of switch and the first or second air cavity switch and first orThe second air cavity side switch is opened simultaneously, makes back-flushing sneak into a large amount of air, and producing a large amount of is bubble, significantlyImprove backwash efficiency.
