Abstract
The utility model discloses a kind of reverse osmosis, nanofiltration membrane central tubes, including tube body and tube surfaces to be evenly distributed with gully-hole, and the pure water end of the tube body is set as hickey, the O-shaped washer of setting at hickey；The gully-hole includes a circular hole, and circular is uniformly distributed the diversion trench of eddy structure.Become to be threadedly coupled at the sealing of pure water end, the stability and leakproofness after increasing membrane component installation, does the extension runner of part helix shape distribution in the through-hole surrounding of pure water collection, as the runner of pure water collection, increase the flow and speed for collecting pure water.
Description
Technical field
The utility model belongs to household water-treatment technology field, more particularly to a kind of reverse osmosis, nanofiltration membrane central tube.
Background technique
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.
It is reverse osmosis, nanofiltration element demand is growing as these water purifiers are reverse osmosis, the periodic replacement of nanofiltration membrane uses, it gathers around
The huge market of the person of having.
Central tube is reverse osmosis, nanofiltration membrane component a basic element of character.Existing central tube has certain limitation,
Through-hole as being equipped in central tube is limited, leads to latus rectum very little, and water flow is little, affects the water mixing performance of membrane component, and because
To have used more diaphragms, cause cost also higher.Secondly the sealing at pure water end is to pass through extruding by two small O-rings
Be sealed isolation raw water, concentrated water seals in, but the material of O-ring is usually rubber, depends this sealing alone and be easy to cause leakage,
There are greater risk, leakage will affect the conductance of pure water, the salt rejection rate of membrane component caused to decline, and reduce filter effect；And only lead to
It crosses O-ring to go to fix, membrane component can be easy unstable when to hydraulic pressure, easily shaken in use, play, be easy to make
At leakage.
Utility model content
In view of the deficiencies of the prior art, that the purpose of the utility model is to provide a kind of water flows is big, sealing effect is good, is not easy
Leakage, and the central tube of the water mixing performance of membrane component is not influenced.
To realize that goal of the invention, the present invention adopt the following technical scheme that:
Reverse osmosis, nanofiltration membrane central tube, including tube body and tube surfaces are evenly distributed with gully-hole, it is characterised in that the tube body
Pure water end is set as hickey, places O-shaped washer at hickey.
Preferably, the gully-hole includes a circular hole, circular is uniformly distributed the diversion trench of eddy structure, water conservancy diversion
Groove depth, to gradually becoming shallower as outside, in this way after raw water becomes pure water through film surface, passes through the return guide trough of eddy structure by circular hole
At water flow vortex, pure water can be made rapidly to flow out by gully-hole, the collection of pure water is accelerated, compared with existing structure, increase
The collecting amount of pure water in unit time, the utilization rate of the water of raising.
Preferably, the diversion trench of eddy structure is arranged 2 or more, more preferably, setting 4.
The beneficial effects of the utility model are embodied in:
(1) become to be threadedly coupled at the sealing of pure water end, the stability and leakproofness after increasing membrane component installation solve
A possibility that being shaken after to hydraulic pressure after membrane component installation.
(2) O-ring double insurance is added by screw thread, solves the hidden danger for being likely to occur leakage.
(3) diversion trench of eddy structure is uniformly distributed in the circular of pure water collection, as the runner of pure water collection, when
After raw water becomes pure water through film surface, by the return guide trough of whirlpool helical structure at water flow vortex, pure water can be made rapid
It is flowed out by gully-hole, accelerates the collection of pure water, compared with existing structure, increase the collecting amount of pure water in the unit time, improved
Water utilization rate.
Detailed description of the invention
Fig. 1 is reverse osmosis, nanofiltration membrane central tube the structural schematic diagram of embodiment 1；
Fig. 2 is reverse osmosis, nanofiltration membrane central tube the structural schematic diagram of embodiment 2.
Specific embodiment
The utility model is described further below in conjunction with drawings and examples.
Embodiment 1
Reverse osmosis, nanofiltration membrane central tube as shown in Figure 1, including tube body 1 and tube surfaces are evenly distributed with gully-hole 2, the pipe
The pure water end of body is set as hickey 3, places O-shaped washer 4 at hickey.
Embodiment 2
Reverse osmosis, nanofiltration membrane central tube as shown in Figure 2, including tube body 1 and tube surfaces are evenly distributed with gully-hole, the tube body
Pure water end be set as hickey 2, O-shaped washer 3 is placed at hickey；The gully-hole includes a circular hole 4, circular hole week
Enclose the diversion trench 5 for being uniformly distributed whirlpool helical structure, the depth of diversion trench 5 is by circular hole to gradually becoming shallower as outside；The whirlpool spiral shell
The diversion trench 5 for revolving structure is arranged 4.
Above technical scheme is only that preferred embodiment of the invention is described, and is not departing from design spirit of the present invention
Under the premise of, the various changes and improvements that this field ordinary engineering and technical personnel makes technical solution of the present invention should all be fallen into
In the protection scope that claims of the present invention determines.
Claims (3)
1. reverse osmosis, nanofiltration membrane central tube, including tube body and tube surfaces are evenly distributed with gully-hole, it is characterised in that the tube body it is pure
