Background technology
The safety and sanitation of tap water more and more cause the great attention of various circles of society, but the threat of drinking water pollution problem, particularly heavy-metal pollution, has a strong impact on HUMAN HEALTH.Straight drink tap makes " direct-drinking water " in terminal tap, and leading built-in filtering material, enables tap water reach and directly drink effect, thus allow the mankind can drink clean healthy water.
At present, general device for purifying potable water only can solve the slight pollution such as colourity, turbidity, microorganism of water to a certain extent, has that purification style is single, the poor problem of decontamination effect improving.Properity as core component filter core affects use-pattern and the effect of purifier.Existing tap water purifier filter core mainly single-material is made, as active carbon filter core, single external pressure ultra-filtration membrane etc., each filter core all coordinates a shell outward, owing to not protecting ultra-filtration membrane, contaminant filter effect is undesirable, cause water-flowing amount to diminish, filter about water-flowing amount only can reach 1 ton of water, and the organic matter removal poor effect such as chlorion in tap water; And simply several filter core is connected, although improve the decontamination effect improving of tap water, there is problems such as taking up room greatly, assembling is complicated, joint quantity is many.The appearance of the composite filter element of filling type filtering layer solves the problems referred to above to a certain extent, and Chinese patent 200420058323.8 adopts hollow fiber ultrafiltration membrane, gac makes composite water-purification filter element; Chinese patent 200910034256.3 discloses a kind of water purification catridge be made up of hollow-fibre membrane and sorbing material, and said sorbing material can be gac, ion exchange resin, KDF etc.; But the life-span length of different filtering material is different in filter core, once a certain filtering layer filtration of material lost efficacy or breakage, needed to change whole composite filter element, caused the waste of other normal filtration layer materials.
Have not yet to see with ion exchange activity Carbon fibe film in order to remove the relevant report such as heavy-metal pollution and peculiar smell, chlorine residue, micro-Organic Pollutants in water.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of one multimembrane composite filter element, by the filter cartridge construction of multimembrane composite integrated, filter effect reaches the safest, each filtering membrane shares same shell, the dismantled and assembled combination between adjacent membranes, and integral filter core assembling is safeguarded efficient and convenient.
For achieving the above object, the utility model is achieved through the following technical solutions:
One multimembrane composite filter element, comprise a shell and interior ultra-filtration membrane thereof and ion exchange activity Carbon fibe film, be respectively equipped with ultra-filtration membrane in two ends end to end at ion exchange activity Carbon fibe film, described ion exchange activity Carbon fibe film is the film core combined by ion-exchange fiber and activated carbon fiber.
Further, described ion exchange activity Carbon fibe film and ultra-filtration membrane are inserted in the filtering chamber of shell by rotation mode, and shell one end is for filtering entrance, and the shell the other end is filtering outlet.
Further, described shell is combined by upper housing, middle shell and lower housing, between housing, joint is provided with O RunddichtringO, and upper casing, mesochite and lower casing form membrane filtration chamber and revolve successively to the other end from one end establishes ultra-filtration membrane, ion exchange activity Carbon fibe film and ultra-filtration membrane.
Further, described ultra-filtration membrane is become by ultra-filtration membrane core and film head group, and film head is sleeve-shaped, and ultra-filtration membrane core one end is also fixing through the cylinder chamber of film head, and all sides of film head are provided with annular recess and form airtight membrane filtration passage for rotating O RunddichtringO and coordinating with housing.
Further, the inner chamber of described middle shell is hierarchic structure membrane filtration chamber, and wherein coordinate with the film core segment of ultra-filtration membrane compared with osculum end, large mouth end coordinates with the film head part of ion exchange activity Carbon fibe film and another ultra-filtration membrane.
The utility model beneficial effect is as follows:
1, save filter housing quantity, reduce costs, reduce joint.
2, filter effect reaches the safest, first come filtering silt, iron rust, bacteriophage by ultra-filtration membrane, again can the objectionable impurities such as removal heavy metal, harmful organic substance, peculiar smell, chlorine residue by ion exchange activity Carbon fibe film, can secondary pollution be solved by ultra-filtration membrane more below, ensure drinking water safety.
3, ion exchange activity Carbon fibe film and ultra-filtration membrane are screwed in the membrane filtration chamber of shell, can change wherein cracky or reach the film core in life-span, avoid a filter element damaged and change whole composite filter element.
