Description
Technical field
The invention belongs to water purification filter technical fields, more particularly to a kind of reverse osmosis, nanofiltration membrane component.
Background technology
With the increasingly raising of people's living standard, household water treatment apparatus is used by more and more families, using anti-
Infiltration, nanofiltration membrane component water purifier product because of compact, the reasons such as easy for installation more and more popularize huge numbers of families.
Existing reverse osmosis membrane filtration structure includes mainly central tube and rolls the membrane component on central tube, existing membrane component pure water
End sealing is push-in using double O-rings, and the pure risk-in leakage of such frame mode such as O-ring coordinates not tight with slot
It is close, shaken leakage etc. caused by generating gap by differential pressure.Again because putamina inner wall surface is smooth, the water blocking on membrane component
Circle is easy to happen sliding phenomenon, to cause sealing effect to decline, influences pure water water quality when being under pressure.
Invention content
In view of the deficiencies of the prior art, the object of the present invention is to provide a kind of reverse osmosis, nanofiltration membrane component, it has sealing
Property it is good, there is no shake, leakage etc. hidden danger, in addition retaining ring position fix, be not in slide up and down phenomenon.
To realize that goal of the invention, the present invention take the following technical solution：
A kind of reverse osmosis, nanofiltration membrane component, including central tube, filtration membrane elements, retaining ring and shell, it is characterised in that institute
Filtration membrane elements are stated to roll centered on the central tube together, the shell include upper end end face and contain lower end surface
Cylinder, the central tube includes tube body and tube surfaces are evenly distributed with gully-hole, and the pure water end of the tube body is set as external screw thread and connects
Mouthful, the O-shaped washer of setting at hickey is equipped in the lower end surface of the cylinder containing lower end surface and central tube pure water end
Corresponding internal thread, the two are threadedly coupled；Retaining ring is cased at filtration membrane elements water inlet port, retaining ring edge protrusion exists
The outside of filtration membrane elements, and cover at the barrel port containing lower end surface, retaining ring is blocked in the upper end end face of the shell
Edge；The filtration membrane elements include water inlet grid, and water inlet grid is set between two panels film, the water inlet grid, including
It is cylinder silk to have diamond shape, rectangular or polygon grid, the weft and warp made of weft and warp knitting
Line makes spiral yarn shaped continuous guiding gutter on the surface of cylinder silk thread.
Preferably, the depth of the continuous diversion trench of the cylinder silk thread is the radius of cylinder silk thread.
More preferably, the material of the cylinder silk thread is PP, the diameter of silk thread is 0.02in, continuous water conservancy diversion groove depth
0.01in。
Preferably, the gully-hole of the central tube includes a circular hole, circular is uniformly distributed whirlpool spiral
The diversion trench of structure, water conservancy diversion groove depth is by gully-hole to gradually becoming shallower as outside.
Preferably, the upper diversion trench of the central tube is arranged 2 or more.
Beneficial effects of the present invention are embodied in：
(1) become to be threadedly coupled at the sealing of pure water end, increase the stability and leakproofness after membrane component installation, solve
The possibility shaken after to hydraulic pressure after membrane component installation.
(2) retaining ring can play the role of sealed external putamina with putamina close-fitting, and play the work of sealing membrane component
With, and it is not easily to fall off.
(3) O-ring double insurance is added by screw thread, solves the hidden danger for being likely to occur leakage.
(4) the extension runner that the distribution of part helix shape is done in the through-hole surrounding of pure water collection, as the runner of pure water collection,
After raw water becomes pure water through film surface, by the return guide trough of whirlpool helical structure at flow vortex, pure water can be made rapid
Flowed out by gully-hole, accelerate the collection of pure water, compared with existing structure, increase the collecting amount of pure water in the unit interval, carry
The utilization rate of high water.
(5) weft and warp that water inlet grid uses are the net obtained in this way equipped with spiral yarn shaped continuous diversion trench
For trellis at multiple helical structures, it is out-of-date to be flowed through in water, can form vortex, increases the flow velocity and impact force of water, reduces pollutant
The possibility being attached on grid, to not it is easier that membrane component dirt is stifled.
