The specific embodiment
Below with reference to accompanying drawing and combine embodiment that the utility model is elaborated.Need to prove, under the situation of not conflicting, below characteristic among each embodiment and the embodiment can make up each other.
Among one of them embodiment of the utility model, a kind of flushable external-compression type ultrafiltration element kit is provided, referring to Fig. 1, the flushable external-compression type ultrafiltration element kit in the present embodiment comprises filter housing 100 and the filter core 200 that places in the filter housing 100.
One end of said filter housing 100 is a water inlet end, and the other end is the water side, is provided with former water general import 121 at the water inlet end of filter housing 100, is provided with water purification general export 131 and blowdown general export 132 in the water side of filter housing 100.Therein among embodiment; Filter housing 100 comprises the cylindrical shell 110 of both ends open, is socketed in this cylindrical shell 110 two ends outside first end cap 120 and second end cap 130 respectively; Said first end cap 120 is provided with said former water general import 121, and said second end cap 130 is provided with water purification general export 131 and blowdown general export 132.
Said filter core 200 comprises water purifying chamber 240 that is formed in the said filter housing 100 and many hollow fiber ultrafiltration membrane silks 230 that place in this water purifying chamber 240; The blowdown outlet 222 that the wall of said water purifying chamber 240 is provided with the original water inlet 211 that is communicated with said former water general import 121, the pure water inlet 221 that is communicated with said water purification general export 131 and is communicated with said blowdown general export 132; The mouth of pipe sealing of said hollow fiber ultrafiltration membrane silk 230 1 ends, the other end mouth of pipe is communicated with said pure water inlet 221; Between the end cap of said water purifying chamber 240 and said filter housing 100 water sides, be provided with separate water-purifying cavity 310 and soil chamber 320; Said water-purifying cavity 310 is near said water purifying chamber 240; And be communicated with said water purification general export 131 with said pure water inlet 221; Said soil chamber 320 is away from water purifying chamber 240, and is communicated with said blowdown general export 132 with said blowdown outlet 222.Running water gets in the water purifying chamber 240 from former water general import 121, original water inlet 211; Under the pressure effect of running water; Hydrone sees through hollow fiber ultrafiltration membrane silk 230, and flows to the water side by the interior pipe of film silk, and impurity then is blocked in water purifying chamber 240 inside by hollow fiber ultrafiltration membrane silk 230.When flushing, flush switch 400 is opened, because the blowdown resistance to flow output is few, hollow fiber ultrafiltration membrane silk 230 resistances are big, and most of current are gone out through the blowdown outlet, takes away the impurity that system water stays, and reaches the effect of flushing hollow fiber ultrafiltration membrane silk 230.The water purification that filter core 200 is made is collected in the water-purifying cavity 310, discharges through water purification general export 131, and the wastewater collection that produces during filter core 200 blowdowns is flowed out through blowdown general export 132 in soil chamber 320.The main effect of soil chamber 320 is that sewage is focused on a place; So; Water purification and sewage are separated and come; Simultaneously the hollow fiber ultrafiltration membrane silk has strengthened with the distance of pollutant, the hollow fiber ultrafiltration membrane silk is away from pollutant, has reduced the risk that the hollow fiber ultrafiltration membrane silk is polluted in the pollutant backflow once more.
Therein among embodiment; In the water inlet end of said filter housing 100 and water side, be sealedly connected with first end socket 210 and second end socket 220 respectively; Surround said water purifying chamber 240 by said filter housing 100 inwalls, said first end socket 210 and said second end socket 220; And said first end socket 210 is provided with said original water inlet 211; Said second end socket 220 is provided with said pure water inlet 221 and said blowdown outlet 222; Between said second end socket 220 and said filter housing 100 second end caps 130, be provided with dividing plate 300, the chamber between said second end socket and said filter housing 100 second end caps 130 be divided into said water-purifying cavity 310 and said soil chamber 320 by this dividing plate 300.
Preferably, said blowdown outlet 222 is more than two.Further preferred, said blowdown outlet 222 is three, and three blowdown outlet 222 geometric centers with said second end socket 220 are that the center is along circumferentially being uniformly distributed with.Adopt the beneficial effect of plural blowdown outlet 222 to be: because each flushing can't look like in the ideal so thorough; After each flushing; The blowdown exit has the pollutant deposition, and adding the blowdown export volume through increase can disperse deposit more, just equals to have increased washing time comparatively speaking; Make blowdown more thorough, improve developing result.
Preferably, said hollow fiber ultrafiltration membrane silk 230 axially is provided with along said filter housing, and its two ends are separately fixed on said first end socket 210 and said second end socket 220.
Preferably, said original water inlet 211 and said blowdown outlet 222 eccentric settings are to reach the purpose of abundant flushing.
Preferably, said first end socket 210 is formed by epoxy resin cure with said second end socket 220.Utilize epoxy resin that hollow fiber ultrafiltration membrane silk 250 is blocked near the mouth of pipe of water inlet end.
Preferably, said flush switch 400 is a mechanical switch, and whole so flushable external-compression type ultrafiltration element kit need not power up the work of getting final product.
Among another embodiment of the utility model, a kind of water purifier is provided, it comprises the said flushable external-compression type ultrafiltration element kit of the foregoing description.
The above embodiment has only expressed several kinds of embodiments of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
