Description
Technical field
This utility model relates to the filter element of a kind of water purification, refers specifically to a kind of reverse osmosis membrane filter element in water purifier.
Background technology
Reverse osmosis membrane filter element is a kind of element common during water processes, and it is anti-be wound on central canal that it includes central canal
Permeable membrane, this reverse osmosis membrane has water purification passage and dense aquaporin, and the filter element after assembling is placed in housing, during use,
Former water enters from one end of housing, and under the effect of former water pressure, one end of the reverse osmosis membrane after coiling enters reverse osmosis
Film, through the lower water purification entrance central canal formed of effect of reverse osmosis membrane, then flows out from the one or both ends of central canal, and dense
Water side is flowed out from the other end of reverse osmosis membrane, interface through the other end of housing.
Although above-mentioned reverse osmosis membrane filter element also can realize the purpose of water purification, but axial after rolling along reverse osmosis membrane due to former water
Flowing, runner is short, and producing water ratio is low, and irrigation flow rate is little, rinses the most thorough.
To this end, people design the anti-seepage membrane filter element of lateral intake, if China's Authorization Notice No. is CN102976447B
" a kind of lateral flow type anti-seepage membrane element ", but its dense water outlet is still on one end of reverse osmosis membrane, and former water flow to neighbour
During nearly central canal, a part for meeting the most never rubber fabric flows out, i.e. flows out from outlet around shortcut, the most former current
The stroke of warp is the most relatively short, and processes inconvenience.
Utility model content
Technical problem to be solved in the utility model is the present situation for prior art, it is provided that a kind of producing water ratio is high, flushing
Reverse osmosis membrane filter element thorough and easy to process.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is: a kind of reverse osmosis membrane filter element, including center
Pipe and the reverse osmosis membrane being wound on central canal, have dense aquaporin and water purification passage, its feature in described reverse osmosis membrane
It is: be provided with radial direction dividing plate in described central canal and central canal inner space is separated in the first inner chamber and second vertically
The first through hole of connection the first inner chamber and the second through hole connecting the second inner chamber is had on chamber, and the sidewall of described central canal；
Two ends after described reverse osmosis membrane winding seal and make dense aquaporin and water purification passage arrange along coiling direction, this reverse osmosis membrane
The external port of dense aquaporin of winding termination end become former water inlet, the dense water at the winding initiating terminal of this reverse osmosis membrane leads to
The inner port in road then connects the first through hole；And the external port of the water purification passage of the winding termination end of this reverse osmosis membrane is airtight, should
The inner port of the water purification passage at the winding initiating terminal of reverse osmosis membrane then connects with the second through hole.
In order to the former water entering reverse osmosis membrane is filtered in advance, it is preferred that outside the described reverse osmosis membrane after winding also
It is enclosed with silk screen.
In such scheme, it is preferred that the external port of described water purification passage carries out airtight by marine glue.
In order to avoid twice pollution, the outer wall of described central canal is glued with by the inner port of described dense aquaporin and water purification
The fluid sealant that the inner port of passage separates mutually.
It is preferred that the axial length of described first inner chamber is more than the axial length of the second inner chamber.
Compared with prior art, due to former water of the present utility model equally from reverse osmosis membrane wind after circumference entrance, former water
Flow to as reverse osmosis membrane winding tangential, current are more easier than axial impact by pollutant to the tangential impact of reverse osmosis membrane
Washing away, the denseest water and water purification flow out from the two ends of central canal respectively, and this makes former water must cover reverse osmosis membrane winding
Enter into central canal after stroke, therefore equal volume, use same reverse osmosis membrane in the case of, can extend significantly
Former water flow passage, makes producing water ratio be improved obviously, and this using central canal two ends as dense water and the outlet of water purification,
Processing is got up more convenient, is also easy to implement.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment；
Fig. 2 is the A-A sectional view in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As depicted in figs. 1 and 2, this reverse osmosis membrane filter element includes central canal 1 and the reverse osmosis membrane being wound on central canal
2, wherein, it is provided with radial direction dividing plate 11 in central canal 1 and central canal inner space is separated into vertically the first inner chamber 12
With the second inner chamber 13, and have connection the first through hole 14 of the first inner chamber on the sidewall of central canal 1 and connect the second inner chamber
The second through hole 15, this first, second through hole can be multiple apertures respectively, the most spaced apart；Can also
It it is elongated hole vertically.
There is in above-mentioned reverse osmosis membrane 2 dense aquaporin 21 and water purification passage 22；In the deployed state, reverse osmosis membrane is square
Shape, the one group limit parallel with coiling direction is coated with marine glue 3 so that after winding, reverse osmosis membrane two ends seal, and make dense
Aquaporin and water purification passage are arranged along coiling direction.The dense aquaporin port of the winding termination end of this reverse osmosis membrane, the denseest water
The external port of passage becomes former water inlet, and the port of the dense aquaporin at the winding initiating terminal of this reverse osmosis membrane is dense aquaporin
Inner port, the inner port of this dense aquaporin connects the first through hole 14, is i.e. connected with the first inner chamber 12 through the first through hole 14
Logical；And the port of the water purification passage of the winding termination end of this reverse osmosis membrane is external port, the external port of this water purification passage is airtight,
Preferably, the external port of water purification passage carries out airtight by marine glue 4, and at the winding initiating terminal of this reverse osmosis membrane
The port of water purification passage is inner port, and the inner port of this water purification passage connects with the second through hole 15, namely with second
Inner chamber 13 connects.
In order to make the former water entered to filter further, outside reverse osmosis membrane after the coiling, also it is enclosed with silk screen 5.And in
The fluid sealant 6 inner port of dense aquaporin separated mutually it is glued with the inner port of water purification passage, to keep away on the outer wall of heart pipe
Exempt from secondary pollution.
Preferably, in the present embodiment, the axial length of the first inner chamber 12, more than the axial length of the second inner chamber 13, makes
Dense water and water-purifying cavity volume are able to reasonable layout.
After using said structure, comparing with 1812 general reverse osmosis membranes and understand afterwards, former water flow passage will extend more than one times,
Producing water ratio will improve by about one time, therefore under conditions of equal volume and reverse osmosis membrane, use the present embodiment i.e. to can reach water
Imitate two grades, and owing to former water flows into circumferencial direction, flow to the tangential of the coiling direction into reverse osmosis membrane, this tangentially
The current of impact are more easy to wash away the dirt being attached in dense aquaporin, therefore, rinse the most thorough.
