Description
Technical field
The present invention relates to a kind of reverse osmosis membrane part.
Background technology
Reverse osmosis membrane part is the part commonly used in water purifier.In order to save space and easy to install and use, traditional is anti-
Infiltration membrane element is all by the way of by single Mo Daiyan centers water producing pipe spiral winding, to ultimately form the close film bag of multilayer
It is cylindric that layer is constituted, and its central tube is as collector pipe, and the collector pipe of the multilayer pure water collection of film bag to the heart in the component is that is, pure
Water flow passage direction is inside spin form, and its runner is long, and pure water flow passage resistance force of waterproof is big, and pure water flow velocity is slow, and causes reverse osmosis membrane part
Effective counter-infiltration reduce, cause aquifer yield to reduce, and collector pipe only one goes out pure water, its using when have larger limitation.
Cooperation of the existing reverse osmosis membrane part to water purification machine, which is installed, to be also limited.In addition, in existing reverse osmosis membrane part only one of which
Heart pipe is supported as fixed, and peripheral film bag is centered around around central tube, and border does not support stress point, therefore insecure, when
When central tube is by external force, membrane component easily forms taper, there is friction between film bag and film bag, causes diaphragm to be damaged, salt rejection rate
Decline.
In addition, have also appeared the reverse osmosis membrane part being made up of multiple films bag at present.As shown in FIG. 1 to 3, this multimembrane
Bag reverse osmosis membrane part mainly includes center collector pipe 10 and multiple films bag 20, the side of center collector pipe 10 provided with some rows with
20 corresponding water inlets 40 of each film bag, the inside of center collector pipe 10 is close to end provided with cut-off 50, and its principle is with tradition
It is similar, film bag is only changed into multiple films bags, single flow channel length is which reduced, and alleviate portion of runner resistance
Power, but still using central tube as collector pipe, therefore there are still the inherent shortcoming of conventional reverse osmosis membrane element, purified water
Concentrated by the selvage guide of each film bag 20 and be flowed into center collector pipe 10, i.e., catchmented from periphery to center, and pure water Zhi Cong centers
One end outflow of collector pipe 10, because multimembrane bag purified water all focuses on a center water producing pipe, causes treated water resistance to water-flow
Pressure increase in increase, flows decrease, film bag.Reverse osmosis membrane aquifer yield is influenceed very big by reverse osmosis membrane, pressure increase in film bag,
Effective reverse osmotic pressure is caused to reduce, so as to cause membrane component total yield discharge reduction, diaphragm utilization rate declines.
The content of the invention
The technical problems to be solved by the invention be overcome the deficiencies in the prior art there is provided a kind of runner is short, resistance is small, stream
The external spiral multipage reverse osmosis membrane that fast fast, aquifer yield is big, diaphragm utilization rate is high.
The technical solution adopted in the present invention is：The present invention includes central tube, at least two films bag and film bag quantity
Consistent outer end collector pipe, the side of the outer end collector pipe is provided with several water inlets, and institute is fixed in the inner of the film bag
State on central tube, each film bag is closely wound in the same direction along the central tube successively, form the cylinder that multilayer film bag layer is constituted,
In the outer end collector pipe is wrapped in by the outer end of film bag, raw water is entered in film bag by counter-infiltration, and passes through institute
State water inlet to be collected into the outer end collector pipe, then gone out by the end of the outer end collector pipe in pure water, the film bag
Pure water is by center helical flow laterally.
The film bag includes reverse osmosis membrane, selvage guide, grid, seal.
The inner of film bag is fixed or is adhesively fixed by ultrasonic bonding between the central tube.
The one or both ends water outlet of the outer end collector pipe.
The beneficial effects of the invention are as follows：Because the present invention includes central tube, at least two films bag and film bag quantity one
The outer end collector pipe of cause, the side of the outer end collector pipe is provided with several water inlets, and the inner of the film bag is fixed on described
On central tube, each film bag is closely wound in the same direction along the central tube successively, forms the cylinder that multilayer film bag layer is constituted, institute
State film bag outer end the outer end collector pipe is wrapped in, raw water is entered in film bag by counter-infiltration, and by described
Water inlet is collected into the outer end collector pipe, then is gone out by the end of the outer end collector pipe pure in pure water, the film bag
Shui You centers helical flow laterally；Instant invention overcomes the defect of prior art and deficiency, multipage film bag can reduce runner
Length, reduces on resistance, the central tube without gully-hole, the structure support of the film bag is only used as, in the outer end of film bag
The outer end collector pipe is set, the production water for collecting each film bag, pure water in the film bag is by center spiral shell laterally
Eddy flow is moved, and can so reduce the flow resistance of production water, is mitigated the pressure in film bag, is improved flow velocity, effectively improve aquifer yield；Due to
There is a central tube every page of film bag periphery as water effect is collected, while sustainable fixed whole membrane component, will not go out
An existing central tube force unbalance causes the problem of membrane component deformation is tapered, has multiple strong points, stress when by external force
Uniformly, it is indeformable, the customer service defect of prior art so that membrane component uses more stable；Therefore runner of the present invention is short, resistance is small,
Flow velocity is fast, aquifer yield is big, diaphragm utilization rate high, is a kind of external spiral multipage reverse osmosis membrane.

Embodiment
As shown in Figure 4 to 7, the external spiral multipage reverse osmosis membrane of the present embodiment include central tube 1, at least two films bag 2,
The outer end collector pipe 3 consistent with the film 2 quantity of bag, the side of the outer end collector pipe 3 is provided with several water inlets 4, described
The inner of film bag 2 is fixed on the central tube 1, in the present embodiment, leads between one end of the film bag 2 and the central tube 1
Cross ultrasonic bonding to fix or be adhesively fixed, each film bag 2 is closely wound in the same direction along the central tube 1 successively, forms multilayer
The cylinder that film bag layer is constituted, in the outer end collector pipe 3 is wrapped in by the outer end of film bag 2, raw water is penetrated into by reverse osmosis
Enter in the film bag 2, and be collected into by the water inlet 4 in the outer end collector pipe 3, then pass through the outer end collector pipe 3
End go out pure water, the pure water in the film bag 2 is by center helical flow laterally, and the structure of the film bag 2 is with conventional film bag
Similar, mainly including reverse osmosis membrane, selvage guide, grid, seal, the main distinction is exactly inner closing, the outer end water outlet of film bag,
The two ends of outer end collector pipe 3 water outlet simultaneously, naturally it is also possible to which one end water outlet, other end is blocked with structure, using flexible.This hair
Bright can be improved in the case of identical diaphragm consumption arbitrarily brings out purified water in aquifer yield, and the equipment being conveniently applied to.
Instant invention overcomes the defect of prior art and deficiency, multipage film bag can reduce flow channel length, reduce resistance, institute
State on central tube 1 without gully-hole, be only used as the structure support of the film bag 2, the outer end collection is set in the outer end of film bag 2
