Description

With the filtering apparatus for drinking water for folding membrane cartridge

Technical field

Water-treatment technology field is the utility model is related to, more particularly to it is a kind of with the Drinking Water Filtration dress for folding membrane cartridge Put.

Background technology

Direct drinking need not boil i.e. capable of direct drinking, be a kind of hygienic and convenient drinking water.At present, most domestic Direct drinking preparation facilities from the point of view of preparation technology, if raw water quality is preferable, is adopted all using counter-infiltration as main filters Reverse osmosis requirement is all up with the filtering of PP cottons, charcoal absorption or ultrafiltration, counter-infiltration can remove the ion in raw water, production Water is pure water, although water quality safety is high, because counter-infiltration eliminates the mineral element beneficial to body simultaneously, therefore it is produced Water is not appropriate for as long-term direct drinking.Currently used direct drinking is mainly filtered with sand filtration-reverse osmosis process, wherein instead Permeable membrane can remove most divalent ion and 99% mineral matter.The mineral matter that part is beneficial to people in water is so eliminated, Water is set to lose the nutrition of itself.

Utility model content

In order to solve the above problems, the purpose of this utility model is to provide a kind of with the Drinking Water Filtration for folding membrane cartridge Device.

The utility model is achieved through the following technical solutions：A kind of filtering apparatus for drinking water with folding membrane cartridge, bag Include the coarse filter for passing sequentially through pipeline connection, ultrafilter, booster pump and nanofiltration device；Polypropylene plastics system is placed in the coarse filter Standby folding membrane cartridge, folding the membrane cartridge internal diameter 28mm, filter core external diameter 68mm；The ultrafilter ecto-entad is nothing successively Spin layer of cloth, carbon-fiber film, milipore filter and PE ultrafiltration cores.

Further, the folding membrane cartridge is using low ebb-peak-low ebb-peak-Gao Gu-peak-low ebb folding mode circulation folding Folded film layer filter core.

Further, in the film layer filter core, the air line distance between two low ebbs of arbitrary neighborhood is equal.

Further, the PE ultrafiltration cores are polyethylene foam-materials, in milipore filter.

Further, there is filtering through hole on the milipore filter, and be sheathed in carbon-fiber film.

The beneficial effects of the utility model：The utility model uses thick with the filtering apparatus for drinking water for folding membrane cartridge Filter -3 grades of ultrafiltration-nanofiltration water process, the clearance of original mineral matter in drinking water is reduced, retains the mineral beneficial to human body Matter, make direct drinking more nutrition, it is more healthy.The material for core of coarse filter is polypropylene screen, provides best protection for filter membrane and ensures Free from admixture comes off, binder free, harmless to biology, and filter efficiency is high, and up to more than 99%, resistance is small, and no fiber departs from, non-photosensitivity Property, filter area is big, service life length.

The technical solution of the utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.

Brief description of the drawings

Fig. 1 is the utility model with the filtering apparatus for drinking water structural representation for folding membrane cartridge；

Fig. 2 is the cross-sectional view for folding membrane cartridge；

Fig. 3 is the structural representation of ultrafilter in ultrafiltration apparatus.

Reference：1 coarse filter, 2 ultrafilters, 3 booster pumps, 4 nanofiltration devices, 11 fold membrane cartridge, 12 filter core internal diameters, 13 filters Core external diameter, 21 nonwoven layers, 22 carbon-fiber films, 23 milipore filters, 24PE ultrafiltration cores

Embodiment

Fig. 1 is filtering apparatus for drinking water structural representation of the utility model with folding membrane cartridge, and Fig. 2 is folding membrane filtration The cross-sectional view of core, Fig. 3 are the structural representation of ultrafilter in ultrafiltration apparatus.As Figure 1-3, it is a kind of to carry folded membrane The filtering apparatus for drinking water of filter core, including pass sequentially through the coarse filter 1 of pipeline connection, ultrafilter 2, booster pump 3 and nanofiltration device 4； Place folding membrane cartridge 11 prepared by polypropylene plastics in the coarse filter 1, the folding membrane cartridge internal diameter 12 is 28mm, filter core External diameter 13 is 68mm；The ultrafilter ecto-entad is nonwoven layer 21, carbon-fiber film 22, milipore filter 23 and PE ultrafiltration cores successively 24.The membrane cartridge that folds is to be filtered using the film layer of low ebb-peak-low ebb-peak-Gao Gu-peak-low ebb folding mode loop collapsing Core.In the film layer filter core, the air line distance between two low ebbs of arbitrary neighborhood is equal.There is filtering through hole on the milipore filter, And it is sheathed in carbon-fiber film.The PE ultrafiltration cores are polyethylene foam-materials, in milipore filter.

In use, drinking water enters coarse filter by pipeline, fold membrane cartridge and fold unit ring by multiple identicals Head and the tail, which connect and compose, folds film layer filter core, and the distance of high paddy to peak is less than low ebb to the distance at peak.With existing folding membrane cartridge phase Than, add 30% or so filter area, water flux is bigger, it is pressure-resistant it is higher, water outlet is more stable.Inner pressed filter core, i.e. current Mode for it is interior enter it is outgoing, impurity is trapped within inside filter core, when filter core is lifted, impurity is just taken away in the lump, is not in The phenomenon of polluted water.Remove water-borne glue body and bacterial virus, the complete water of hyperfiltration treatment by ultrafilter makes water by booster pump Pressure enters nanofiltration after being higher than 0.7MPa, hardness, small organic molecule and the chloroform gone in water removal, retains water mineral.

The utility model abandons that water-flowing amount in the prior art is small, removes the undesirable single external pressure of the organic matter effect such as chlorion Milipore filter.Described ultrafilter sequentially sets PE ultrafiltration cores, carbon-fiber film and non-woven fabrics from inside to outside.Described non-woven fabrics can mistake The macroscopic large granular impurities such as filter mud sand, iron rust, play a good protection to carbon-fiber film；Described carbon-fiber film It may filter that the organic matter such as chlorion in drinking water, stupid；Filtering and protective effect through above-mentioned two filter membrane, described PE ultrafiltration Core goes the harmful substances such as oil removal colloid bacterial virus and heavy metal, and water-flowing amount is highly stable.

The utility model is not limited to the technical scheme described in the above-described embodiment and examples, above-mentioned embodiment and explanation Content simply illustrates principle of the present utility model described in book, on the premise of the spirit and scope of the utility model is not departed from, this Utility model also has various changes and modifications, and these changes and improvements are both fallen within claimed the scope of the utility model.
