Description

Domestic water filter

The utility model relates to a kind of water filtering device.

The hollow-fibre membrane water filtering device of existing family expenses all is to adopt external-compression type, and water promptly to be clean is pressed to the film outer wall of hollow-fibre membrane by hydraulic pressure.The filtration of doughnut membranous wall, hydrone penetrate membranous wall, enter the centre bore of tunica fibrosa, outwards flow out along centre bore, and other macromolecular substances quilt is every outside film.For a long time and long-pending many, not have good pollution discharge structure, the fenestra of hollow-fibre membrane is clogged by big molecule foreign material entirely, and hydrone is difficult to by membranous wall, reduces or does not have a water purification outflow so that go out water purification speed.The general aquifer yield of this water purifier has only the 1-5 ton, as run into contain in the more family of foreign material water then the life-span shorter.

The purpose of this utility model provide a kind of life-span long, produce water purification amount height, produce good, the service water filter that can automatic pollution discharge of water quality.

The purpose of this utility model is achieved in that

The cannulated tunica fibrosa fitly is arranged in together, and envelope is all filled out in the gap between the film at the two ends of all hollow-fibre membranes and the film has epoxy resin to become fibre bundle.Be installed in the shell that stainless steel tube or engineering plastics make, because hollow-fibre membrane is quite soft, shell can make shape miscellaneous according to user's needs, can be that straight barrel type also can be the shape of flexure type.The gap of hollow fiber membrane bundle two ends and pipe shell also is sealed with epoxy resin, that is to say to make and must be all advance from the centre bore of hollow-fibre membrane through the water of filter, and can not be from the gap between the hollow-fibre membrane or the gap of hollow-fibre membrane and shell wall enter filter.The two ends of pipe shell are sealed by two bowls, the bowl have one the water inlet or the water outlet connecting hole, in internal thread is arranged.Wherein, Wan effect is: one, connect water pipe as water inlet end or connect tap as the blowdown end.Two, anti-pollution.Have one to go out the water purification end on the sidewall of shell.Also can have a plurality of.This is fixed according to using needs.From then on the water that flows out in the end all is through the water after purifying.Ordinary circumstance blowdown end all is that comparison is near going out the water purification end.

Taking the purification process of purifying waste water, the glide path of water in clarifier is such: water is gone into from the water inlet end of filter, be pressed into the centre bore of hollow-fibre membrane, under the hydraulic pressure effect, water flows along centre bore on the one hand, and water has Penetration Signature on the other hand, under this characteristic effect, hydrone passes membranous wall and forms the water that purifies to the film exosmosis, and other macromolecular substances in water is owing to the blowdown end is stored in the centre bore of hollow-fibre membrane by the pass.In the blowdown process, going out the water purification end often is closed, the glide path of water is such: after water enters the centre bore of hollow-fibre membrane from the water source, because going out the water purification end is closed, water is out in the cold to the suitable I of film sidewall infiltration tendency, and water directly flows along the centre bore of hollow-fibre membrane, and drives outside the residual macromolecular substances outflow filter, open this blowdown end after a few minutes, just can make in the fiber fenestra keep clean, unimpeded.After the cleaning, the water that this end flows out is identical with the water quality of water inlet end, does not promptly play the filtration, purification effect.

Use the utility model product can bring following effect: 1. stable performance, the life-span is long, and circulation is big, and system water purification ability is strong, effective, and the product water life-span of this product uses appropriately can reach more than 100 tons greater than 50 tons.2. because the dirt in can discharge filter, thereby be difficult for stopping up, and can oppositely use, promptly go out the water purification end as water inlet end former, former water inlet end and raw sewage disposal end use as going out the water purification end.3. the water purification cleannes height of output.The hollow-fibre membrane of selecting for use fenestra to vary in size as required, the water of energy output different cleaning degree.4. according to the difference that the field, ground is installed, can make the filter that face shaping varies in size.Because hollow-fibre membrane is the crooked soft tubule of energy, can pass the shell of arbitrary shape.

Filter with straight barrel type is that example is elaborated below

Fig. 1 is that outward appearance is the partial sectional view of straight-cylindrical filter

Fig. 2 is the filter housing stereogram

The 1st, advance the outer bowl of water, the 2nd, shell is the water purification port 2(1), the 3rd, hollow-fibre membrane, the 4th, epoxy resin, the 5th, the outer bowl of blowdown, 6 apertures, 7 connecting holes

In conjunction with the accompanying drawings the filter of straight barrel type is implemented to be specifically described.Filtration device structure is roughly the same therewith for the structure of filter of other shape.

By epoxy resin 4 solid envelopes, form hollow fiber membrane bundle and be contained in the shell 2 between the film at proper alignment hollow-fibre membrane 3 two ends together and the film, the shape of shell 2 can be divided into of all kinds as required.The two ends shell wall of shell 2 all has aperture 6.The epoxy resin 4 that envelope is filled out in hollow fiber membrane bundle two ends and shell gap injects from aperture 6, and according to using needs, certainly, the two ends of hollow fiber membrane bundle and shell two ends can not line up, and just hollow fiber membrane bundle is in shell 2 middle parts.Distance between two row's apertures 6 on the shell 2 is less than the distance at hollow fiber membrane bundle two ends at this moment.The water purification of going out port 2(1 is arranged on shell), when having internal thread to prepare against use, port is connected with water tap (valve).Can have a plurality of according to instructions for use.Go out water purification port 2(1) the position general near shell one end--blowdown end, and go out the water purification end distance from the water inlet end that is generally far away.Inserting envelope on the water inlet end of shell 2 and water side respectively has the into outer bowl 1 of water, the outer bowl 5 of blowdown, has internal thread connecting hole 7 on outer bowl 5 in the outer bowl 1 of water inlet, blowdown, and difference can be connected with water tap (valve) with the family expenses water pipe.The effect of the outer bowl 1 of water inlet, the outer bowl 5 of blowdown prevents the pollution of shell to doughnut in addition.Can add one deck screen pack between outer bowl 1 of water inlet and hollow fiber membrane bundle, result of use is understood better like this.Need illustrate be: when between the port of the water inlet end of hollow fiber membrane bundle or water side and shell 2, enough spaces being arranged, can be water inlet outer bowl 1(or the outer bowl 5 of blowdown) on have an internal thread connecting hole 7 envelopes fall., connecting hole 7 is opened on shell 2.
