The specific embodiment
Below with reference to accompanying drawing, also the present invention is described in detail in conjunction with the embodiments.It should be noted that, in the situation that do not conflict, below feature in each embodiment and embodiment can mutually combine.
In one of them embodiment of the present invention, provide a kind of flushable external-compression type ultra-filtration element assembly, referring to Fig. 1, the flushable external-compression type ultra-filtration element assembly in the present embodiment comprises filter housing 100 and is placed in the filter core 200 in filter housing 100.
One end of described filter housing 100 is water inlet end, and the other end is water side, at 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.Therein in embodiment, filter housing 100 comprises the cylindrical shell 110 of both ends open, the first end cap 120 that is socketed in respectively these cylindrical shell 110 outsides, two ends and the second end cap 130, be provided with described former water general import 121 on described the first end cap 120, on described the second end cap 130, be provided with water purification general export 131 and blowdown general export 132.
Described filter core 200 comprises the water purifying chamber 240 be formed in described filter housing 100 and the many hollow fiber film yarns 230 that are placed in this water purifying chamber 240, the blowdown outlet 222 that is provided with the original water inlet 211 be communicated with described former water general import 121, the pure water inlet 221 be communicated with described water purification general export 131 on the wall of described water purifying chamber 240 and is communicated with described blowdown general export 132, the mouth of pipe sealing of described hollow fiber film yarn 230 1 ends, the other end mouth of pipe is communicated with described pure water inlet 221; Be provided with separate water-purifying cavity 310 and soil chamber 320 between the end cap of described water purifying chamber 240 and described filter housing 100 water sides, described water-purifying cavity 310 is near described water purifying chamber 240, and be communicated with described pure water inlet 221 and described water purification general export 131, described soil chamber 320 is away from water purifying chamber 240, and is communicated with described blowdown outlet 222 and described blowdown general export 132.Running water enters in water purifying chamber 240 from former water general import 121, original water inlet 211, under the pressure-acting of running water, hydrone sees through hollow fiber film yarn 230, and flows to water side by the inner tube of film silk, and impurity is blocked in water purifying chamber 240 inside by hollow fiber film yarn 230.When rinsing, flush switch 400 is opened, and because the blowdown resistance to flow output is few, hollow fiber film yarn 230 resistances are large, and most of current export and go out by blowdown, take away the impurity that water processed stays, and reach the effect of washing hollow-fiber ultrafiltration membrane filaments 230.The water purification that filter core 200 is made is collected in water-purifying cavity 310, by water purification general export 131, discharges, and the wastewater collection produced during filter core 200 blowdown, 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 to a place, so, water purification and sewage are separated and come, the distance of hollow fiber film yarn and pollutant has strengthened simultaneously, hollow fiber film yarn is away from pollutant, reduced pollutant and refluxed and again pollute the risk of hollow fiber film yarn.
Therein in embodiment, be sealedly connected with respectively the first end socket 210 and the second end socket 220 in the water inlet end of described filter housing 100 and water side, by described filter housing 100 inwalls, described the first end socket 210 and described the second end socket 220 surround described water purifying chamber 240, and be provided with described original water inlet 211 on described the first end socket 210, be provided with described pure water inlet 221 and described blowdown outlet 222 on described the second end socket 220, be provided with dividing plate 300 between described the second end socket 220 and described filter housing 100 second end caps 130, by this dividing plate 300, the chamber between described the second end socket and described filter housing 100 second end caps 130 is divided into to described water-purifying cavity 310 and described soil chamber 320.
Preferably, described blowdown outlet 222 is more than two.Further preferred, described blowdown outlet 222 is three, and three blowdown outlet 222 edges centered by the geometric center of described the second end socket 220 are circumferentially uniform.Adopt the beneficial effect of plural blowdown outlet 222 to be: because each flushing can't be as so thorough in ideal, after each the flushing, the blowdown exit has accumulation of pollutants, adding the blowdown export volume by increase can disperse deposit more, just equal to have increased comparatively speaking washing time, make blowdown more thorough, improve developing result.
Preferably, described hollow fiber film yarn 230 axially arranges along described filter housing, and its two ends are separately fixed on described the first end socket 210 and described the second end socket 220.
Preferably, described original water inlet 211 and described blowdown export 222 eccentric settings, to reach the purpose of abundant flushing.
Preferably, described the first end socket 210 and described the second end socket 220 are formed by epoxy resin cure.Utilize epoxy resin that hollow fiber film yarn 250 is blocked near the mouth of pipe of water inlet end.
Preferably, described flush switch 400 is mechanical switch, and whole so flushable external-compression type ultra-filtration element 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-compression type ultra-filtration element assembly of above-described embodiment.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore 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.
