Abstract
The utility model discloses a cross -flow ultrafiltration membrane filter core structure, including the sleeve pipe, locate the RO membrane filter core of set intraduct, and detachable connection is at the end cover at sleeve pipe both ends, RO membrane filter core comprises center tube and the reverse osmosis membrane of coiling outside the center tube, the center tube lateral wall is formed with and stretches out sheathed tube pure water port, two the end cover is corresponding into the water port and play water end (W. E. ) mouth of being equipped with respectively, there is the circulation clearance between reverse osmosis membrane and the sleeve pipe, the port and go out between the water end (W. E. ) mouth of intaking is linked together through the circulation clearance, the pressure effect down, the radial inside reverse osmosis membrane of seeing through of partial water gets into the center tube, in addition partial water along the axial through the high -speed formation torrent that flows in circulation clearance, constantly wash the reverse osmosis membrane internal surface, will take away attached to the impurity foreign matter on the reverse osmosis membrane on a small quantity to prevent reverse osmosis membrane's blockage, reduced anti - flushing time, thereby prolonged the life of reverse osmosis membrane filter core effectively.
Description
Technical field
This utility model is related to reverse osmosis membrane technical field of structures, more particularly to a kind of cross-flow ultrafiltration membrane filter cartridge construction.
Background technology
Reverse osmosis purified water process is existing common purifying water process mode, and wherein reverse osmosis membrane filter element is its crucial portion
Part, all by the way of dead-end filtration, i.e., raw water is placed in the upstream of film to existing reverse osmosis membrane filter element, under the promotion of pressure differential,
Water and reverse osmosis membrane is passed through less than the granule of membrane aperture, then retained by reverse osmosis membrane more than the granule in reverse osmosis membrane aperture.Dead end
Filter with the prolongation of filtration time, being trapped granule will form pollution layer on film surface, increase filtration resistance, in operation pressure
In the case that power is constant, the filtration transmitance of film will decline.Therefore, dead-end filtration can only be carried out intermittently, it is necessary to periodically right
Reverse osmosis membrane carries out backwash and cleaning water is can guarantee that to remove the layer of contaminants on film surface,.But continually recoiled
Wash, the service life of reverse osmosis membrane can be reduced, increase clean water treatment cost.
Utility model content
Technical problem to be solved in the utility model is to provide the cross-current type ultrafiltration of a kind of simple structure, long service life
Membrane filtration cored structure.
To solve the technical scheme that above-mentioned technical problem is adopted：A kind of cross-flow ultrafiltration membrane filter cartridge construction, including sleeve pipe,
Located at the reverse osmosis membrane filter element of inside pipe casing, and detachable connection is in the end cap at sleeve pipe two ends, the reverse osmosis membrane filter element by
Central canal and the reverse osmosis membrane outside central canal are constituted, and the center tube side wall is formed with the pure water port for stretching out sleeve pipe,
End cap described in two is correspondingly provided with respectively into water port and water outlet port, there are passage gaps between the reverse osmosis membrane and sleeve pipe,
It is connected by passage gaps between the water inlet port and water outlet port.
Further, described sleeve pipe inwall forms spiral lines so that the water for flowing through passage gaps forms spiral turbulent flow.
Further, connected using thread seal between the end cap and sleeve pipe.
Beneficial effect：In this cross-flow ultrafiltration membrane filter cartridge construction, water inlet port and water outlet port are respectively at sleeve pipe two ends,
Under pressure, part water radially-inwardly enters central canal through reverse osmosis membrane, other part water Jing passage gaps vertically
Flow at high speed forms turbulent flow, constantly rinses reverse osmosis membrane inner surface, and the impurity foreign body being attached on a small quantity on reverse osmosis membrane is taken away,
So as to prevent the obstruction of reverse osmosis membrane, backwash number of times is reduced, so as to effectively extend the service life of reverse osmosis membrane filter element.
Description of the drawings
This utility model is described further with reference to the accompanying drawings and examples；
Fig. 1 is the structural representation of this utility model embodiment.
Specific embodiment
With reference to Fig. 1, a kind of cross-flow ultrafiltration membrane filter cartridge construction of this utility model, including sleeve pipe 1, inside sleeve pipe 1
Reverse osmosis membrane filter element, and detachable connection, in the end cap 2 at the two ends of sleeve pipe 1, reverse osmosis membrane filter element is by central canal 3 and in
Reverse osmosis membrane 4 outside heart pipe 3 is constituted, and the side wall of central canal 3 is formed with the pure water port 5 for stretching out sleeve pipe 1, and two end cap 2 is corresponded to respectively
It is provided with into water port 6 and water outlet port 7, there is passage gaps, water inlet port 6 and water outlet port between reverse osmosis membrane 4 and sleeve pipe 1
It is connected by passage gaps between 7.
In the present embodiment, connected using thread seal between sleeve pipe 1 and end cap 2, dismounting and change reverse osmosis membrane can be facilitated
There is certain interval, water inlet end between water inlet port 6, water outlet port 7 inside sleeve pipe 1 in filter element, reverse osmosis membrane filter element
Mouthfuls 6, be connected by circulating pump between water outlet port 7 so that the water of purification to be filtered makees high-speed circulating flowing, water inlet port 6 with
It is connected by passage gaps between water outlet port 7, under pressure, part water is radially-inwardly entered through reverse osmosis membrane 4
Central canal 3, other part water energy Jing passage gaps flow at high speed, and then turbulent flow is formed, and reverse osmosis membrane inner surface is constantly rinsed, will
The impurity foreign body being attached on a small quantity on reverse osmosis membrane is taken away, and so as to prevent the obstruction of reverse osmosis membrane, reduces backwash number of times, from
And effectively extend the service life of reverse osmosis membrane filter element.In addition, without frequently reverse osmosis membrane filter element carried out backwash or
Person changes, and can guarantee that service life of equipment and stability.
Preferably, the inwall of sleeve pipe 1 forms spiral lines so as to flow through the water formation spiral turbulent flow of passage gaps, inwall is convex
The water for acting the spiral lines convection current Jing passage gaps for being formed forms stop, disturbance, so as to form spiral turbulent flow, and then strengthens to anti-
Washing away for permeable membrane surface, further reduces impurity deposition of foreign material on reverse osmosis membrane surface.
Embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but this utility model is not limited to
Embodiment is stated, in the ken that the technical field those of ordinary skill possesses, can be with without departing from this practicality
Various changes can be made on the premise of new objective.
