Description
Technical field:
The present invention relates to water quality, fluid purification treatment technology, specifically a kind of permanent backwash filter of air type that do not dissolve.
Technical background: present purification drainage filtrate device both domestic and external, art designs adopts filter core more, PP for example, PE, activated carbon and ceramic element, titanium, the stainless steel filter core, the milipore filter filter core, counter-infiltration filter core etc., with impurity in water or the liquid, foul, bacterium is filtered, its structure adopts one-level, two-stage or multistage filtering, its principle is to running water or well water by filter core, river carries out press filtration or diafiltration, by filter core impurity foul bacterium in water or the liquid is intercepted, pass through the later other end of filter core for purifying waste water, can allow household drinking water cleaner, more meet environmental protection and health requirements.There is craft or the electronic defective of opening that often promptly needed to open the draining intake valve in about month on April 10th, 2009 by my patent " a kind of draining discharge opeing air admission type backwash filter " of application; Simultaneously, traditional numerous backwash drainage fluid strainers, adopting banked direction control valves to carry out backwash mostly regulates, its defective mainly is that backwash is to adopt former water, stoste or contain the running water of pollutant rather than with the water purification after filtering, clean liquid is as the former water of backwash, stoste, cause water purification, clean sap cavity is infiltrated sordid former water, stoste or running water, thereby influence water purification, the sanitary standard of clean sap cavity, particularly present PE filter core, the backwash range of application of filter cores such as hollow-fibre membrane is because of cost height and technical sophistication, cause the backwash range of application wideless, hindered the particularly large tracts of land popularization of household water filter of water purifier, this filter adopts the principle of air pressure difference that filter core is carried out backwash, with water or liquid after purifying filter core is carried out backwash, avoided former water, stoste is to purifying the pollution in chamber.
Summary of the invention:
Technical problem to be solved in the utility model: overcome the deficiency that prior art exists, particularly air dissolves needs constantly additional inconvenience behind water, liquid, allow backwash filter that the water or the liquid that become with after purifying are polluted in the purification chamber and carry out permanent backwash as former water stoste, this filter technology, it not only can the automatic backwash filter core foul of absorption, foul is rinsed in the water of Yuan Shui, stoste or running water, secondary water-supply flows and drains, and can avoid former water, stoste to purifying the pollution in chamber.
Specification requirement of the present utility model is such:
1) for example fluid sealant and plastics, valve etc. all adopt health level or food grade materials for shell, drainage layer, encapsulant.
2) pressure of former water, stoste is 0.05-0.5MPA or with upward pressure.
The technical scheme that the utility model technical solution problem is adopted:
1), utilize hydraulic pressure or hydraulic pressure and filter core that the former water stoste of Yuan Shui, former sap cavity is carried out press filtration, tackle impurity, foul and the bacterial virus etc. of former water stoste, make water purification, clean liquid.
2), utilize air bag and purify the pressure differential that hydraulic pressure in chamber or Yuan Shui, the former sap cavity or hydraulic pressure moment form, filter core is carried out backwash, emission.
3), the endoporus of filter core is the former sap cavity 9 of former water, interior hole count is more than 1 or 2; Purifying 8 peripheries, chamber is shells 5; Purify that chamber 8 is built-in to be included the air bag 6 of gas or be connected with airbag chamber 12 by interface channel 10; Air bag 6 is arranged in the airbag chamber 12, and air bag 6 numbers are more than 1 or 2; Airbag chamber 12 is connected with Yuan Shui, former sap cavity 9 or is connected with purification chamber 8; Water pocket 6A is connected with purification chamber 8; Former water, stoste import 1 are connected respectively or successively with Yuan Shui, former sap cavity 9 and Yuan Shui, stoste outlet 2.
Realize concrete mode and requirements more of the present invention:
1, all possess city tap-water water supply or secondary water-supply and other hydraulic pressure user etc., as long as pipeline hydraulic pressure or hydraulic pressure reach between the 0.05-0.5MPA or above standard, can realize comparatively ideal backwash filter purification function.
2, for allowing backwash reach effect preferably, air-tightness elastic diaphragm vapour barrier layer 6 preferably adopts high-quality elastomeric materials such as silica gel, but also can adopt other food-grade elastic caoutchoucs or other elasticity vapour barriers.The regional user that rural area and hydraulicefficiency pressure are lower can be installed the hydraulicefficiency pressure booster pump additional and realize.
The beneficial effect that the utility model produces is:
Overcome the deficiency that prior art exists, allow traditional backwash filter cause the technology that purifies the chamber pollution to become and carry out backwash as former water stoste with water or liquid after purifying with contaminant water or liquid backwash, this filter technology, the foul of its not only can be automatic permanent backwash filter core absorption, foul is rinsed in the water of Yuan Shui, stoste or running water, secondary water-supply flows and drains, and can avoid former water, stoste to purifying the pollution in chamber.
