Detailed description of the invention
And the present invention is described in detail in conjunction with the embodiments below with reference to the accompanying drawings.It should be noted that, when not conflicting, the feature in following embodiment and embodiment can combine mutually.
In one of them embodiment of the present invention, provide a kind of Flushable external pressure type ultrafiltration filter core assembly, see Fig. 1 and Fig. 2, Flushable external pressure type ultrafiltration filter core assembly forms primarily of filter housing 100 and the filter core 200 be placed in filter housing 100.
Described filter housing 100 one end is water inlet end, and the other end is water side, and the water inlet end of filter housing 100 is provided with former water general import 121, is provided with water purification general export 131 and blowdown general export 132 in the water side of filter housing 100.Preferably, described filter housing 100 comprises the anti-swollen outer cylinder body 110 of both ends open, is separately positioned on the first end cap 120 and the second end cap 130 of inside, outer cylinder body 110 two ends, described first end cap 120 is provided with described former water general import 121, described second end cap 130 is provided with water purification general export 131 and blowdown general export 132.Outer cylinder body 110 can prevent element kit to be split up when hydraulic pressure is excessive.
The quantity of filter core 200 is two or more, is preferably three.The described filter core 200 of the present embodiment comprises the water purifying chamber 260 be formed in described filter housing 100 and the many hollow fiber film yarns 250 be placed in this water purifying chamber 260, the waste 242 wall of described water purifying chamber 260 being provided with the original water inlet 231 be communicated with described former water general import 121, the pure water inlet 241 be communicated with described water purification general export 131 and being communicated with described blowdown general export 132, the mouth of pipe of described hollow fiber film yarn 250 one end is closed, and the other end mouth of pipe is communicated with described pure water inlet 241.Running water enters in water purifying chamber 260 from former water general import 121, original water inlet 231, under the pressure effect of running water, hydrone is through hollow fiber film yarn 250, and flowing to water side by pipe in hollow fiber film yarn 250, it is inner that impurity is then blocked in water purifying chamber 260 by hollow fiber film yarn 250.When rinsing, flush switch 400 is opened, and because waste resistance is few, hollow fiber film yarn 250 resistance is large, and most of current are gone out by waste, take away the impurity that water processed stays, and reach the effect of washing hollow-fiber ultrafiltration membrane filaments 250.
The Flushable external pressure type ultrafiltration filter core assembly provided due to the embodiment of the present invention has plural filter core 200, and all filter cores 200 work alone, the waste water produced when the water purification that all filter cores 200 are discharged and blowdown is all combined into a place, flows out respectively from water purification general export 131 and blowdown general export 132.Because the volume of single filter core 200 is little, running water flow velocity is wherein very fast, fluid layer is disorderly, can wash away hollow fiber film yarn 250 outer wall by limit working edge, therefore such design can allow ultrafiltration membrane filter element 200 produce good developing result.Because filth-discharging effect is good, the water inventory of crossing of filter core 200 can be made to approach 2t, and reduce consumer's use cost, the popularization for water purifier can play positive role.
Preferably, axially be provided with the inner barrel 210 of both ends open along described filter housing in described filter housing 100, and the first end cap 120 and the second end cap 130 are socketed on the outside at these inner barrel 210 two ends respectively, isolated part 220 is provided with in this inner barrel 210, the lumen segmentation of inner barrel 210 is become the chamber unit that three separate, preferred further, three described chamber unit are that equilateral triangle is arranged.Each chamber unit is sealedly connected with the first end socket 230 near one end of described water inlet end, each chamber unit is sealedly connected with the second end socket 240 near one end of described water side, described water purifying chamber 260 is surrounded by the inwall of described chamber unit, described first end socket 230 and described second end socket 240, and described original water inlet 231 is provided with on described first end socket 230, described second end socket 240 is provided with described pure water inlet 241 and described waste 242.Filter core 200 adopts this structure, has the advantage of compact conformation, is conducive to the volume reducing ultra-filtration element assembly.
Preferably, described original water inlet 231 and described waste 242 eccentric setting, to reach the object of fully rinsing.
Preferably, described first end socket 230 and described second end socket 240 are formed by epoxy resin cure.Epoxy resin is utilized to be blocked by the mouth of pipe of hollow fiber film yarn 250 near water inlet end.
Preferably, dividing plate 300 is provided with between described second end socket 240 and described filter housing 100 second end cap 130, chamber between described second end socket 240 and described filter housing 100 second end cap 130 is divided into the water-purifying cavity 310 near described second end socket 240 and the soil chamber 320 near described second end cap 130 by dividing plate 300, described water-purifying cavity 310 is communicated with described water purification general export 131 with described pure water inlet 241, and described soil chamber 320 is communicated with described blowdown general export 132 with described waste 242.The water purification that three filter cores 200 are made is collected in water-purifying cavity 310, and discharged by water purification general export 131, the wastewater collection produced during three filter core 200 blowdowns, in soil chamber 320, is flowed out by blowdown general export 132.The Main Function of soil chamber 320 is that sewage is focused on a place, so, water purification and sewage are separated, the distance of hollow fiber film yarn and pollutant increases simultaneously, hollow fiber film yarn, away from pollutant, reduces the risk that hollow fiber film yarn is polluted in pollutant backflow again.
Preferably, be mechanical switch in described flush switch 400, whole like this Flushable external pressure type ultrafiltration filter core assembly does not need to power up the work of getting final product.
In another embodiment of the present invention, provide a kind of water purifier, it comprises the described Flushable external pressure type ultrafiltration filter core assembly of above-described embodiment.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
