Description
Technical field
The present invention relates to water purifier technology.More particularly to a kind of water purifier reverse osmosis membrane improved technology.
Background technology
It is exactly to need to discharge (the concentration of substantial amounts of waste water during pure water is produced that traditional water purifier has disadvantage
Water), output portion pure water needs to emit 3-6 parts of waste water, the water purifier of this large amount of waste water of output also need to compared with
Powerful booster pump carries out pressurized treatment.This scientific development advocated with the country and " energy-conservation, the drop built a conservation-minded society
Consumption " requires mutually to deviate from.Additionally, also increasing the live load of preprocessing filter element while wasting water, that is, shorten pre-
Process the service life of filter core.For saving water resource, booster pump operating power is effectively reduced, ensureing the service life of RO films
While effectively improve the purposes such as pure water water quality, occur in that in the industry it is a kind of use two RO films, be respectively to produce water RO film (big flows
Film) and backflow RO films (low discharge film) water purifier technology.The concentrated water amount that backflow RO UF membranes go out is dense relative to product water RO films
Water less can more economize on water, and using flowing back, RO films further separate the concentrated water for producing water RO films, and this part water is pure not as that must take
Water and be to re-use water to be back to raw water and filter again, the condensed water of separation is relative produce water RO films must take pure water ratio (pure water/
Waste water 4:1) discharge capacity is reduced, and so as to reach water saving purpose, the technology can also effectively improve the salt rejection rate of pure water, reaches raising pure
The effect of water water quality.But the pure water technique of backflow is needed using two RO films of existing structure, and needs pipeline by its phase
Connect, cause water purifier volume excessive, increase unnecessary production cost, pipeline is also excessively complicated.
The content of the invention
It is an object of the invention to provide a kind of double film water purification reverse osmosis membranes of one, the body that pure water backflow water purifier is present is solved
The product technical problem such as excessive, pipeline is complicated and production cost increases.
In order to realize upper goal of the invention, the technical solution adopted in the present invention is as follows：
The double film water purification reverse osmosis membranes of one, including putamina, water purification discharge center-pole, the reverse osmosis membrane being wrapped on center-pole
The compound filter structure of piece and diaphragm interlayer (also referred to as water guide layer) adjacent superposition, between putamina and compound filter structure every
From sealing ring, original water inlet, wastewater outlet and pure water inlet；The reverse osmosis diaphragm is bilayer, there is the glue of bonding along its both sides
Mouthful, form the structure of pocket-like；Water purification is evenly equipped with by hole on the water purification discharge center-pole；Water purification discharge center-pole is upper and lower
The mutually isolated structure of two parts cavity；Relative to two parts cavity up and down that water purification discharges center-pole, the reverse osmosis diaphragm
Increase the insulation rubber mouthful of bonding together at middle part, the top half of reverse osmosis diaphragm and water purification are discharged the upper cavity pair of center-pole
The first water purification reverse osmosis membrane should be formed, the latter half is correspondingly formed the second water purification reverse osmosis with the lower cavity of water purification discharge center-pole
Film；Shell one end is original water inlet, and the other end is wastewater outlet；Water purification discharge center-pole one end is the first water purification reverse osmosis membrane
Pure water is exported, and the other end is the pure water outlet of the second water purification reverse osmosis membrane.
Advantages of the present invention and good effect：
In a traditional reverse osmosis membrane structure, the function of double films, i.e. one two film construction form are formed.Can be not
In the case of increasing water purifier volume, simplify connecting line, reduce production cost, realize pure water backflow functionality.
Brief description of the drawings
Fig. 1 is internal structure sectional view of the invention.
Fig. 2 is the structural representation of the double water purification reverse osmosis membranes of one of the invention.
Specific embodiment
Concrete structure of the invention is referring to shown in Fig. 1,2.The double film water purification reverse osmosis membranes of the one, including as the film of shell
The reverse osmosis diaphragm 4 and diaphragm interlayer 3 of shell, the water purification discharge center-pole 6, continuous winding with central through hole 5 on center-pole
The compound filter structure of (also referred to as water guide layer) adjacent superposition, between putamina and compound filter structure and be enclosed within compound drainage
On isolating seal circle 1, the original water inlet of putamina one end, the wastewater outlet of the putamina other end and water purification discharge center-pole in structure
Pure water inlet.
The reverse osmosis diaphragm 4 is bilayer, the glue mouthful 9,7 for having bonding along the both sides up and down of its winding direction, forms pocket
The structure of shape.Water purification is evenly equipped with the water purification discharge center-pole 6 by hole 5, center-pole 6 is entered by the direction of reverse osmosis diaphragm 4
Thus water purification is entered interior water purification by hole 5.In order to realize the function of double films, water purification discharge center-pole 6 is designed to upper and lower two
The mutually isolated structure of part cavity, referring to the interlayer 8 in the middle part of the center-pole in figure, and then realizes the respective pure water inlet of double films
Passage.Relative to two parts cavity up and down that water purification discharges center-pole, the reverse osmosis diaphragm increases bonding together at middle part
Insulation rubber mouthfuls 2, the first water purification is correspondingly formed against oozing by the upper cavity of the top half of reverse osmosis diaphragm 4 and water purification discharge center-pole
Permeable membrane, the latter half is correspondingly formed the second water purification reverse osmosis membrane with the lower cavity of water purification discharge center-pole.It is original in shell one end
Water inlet, the other end is wastewater outlet, and the structure is identical with traditional water purifier, therefore not shown in figure.In water purification discharge
Core bar one end is the pure water outlet of the first water purification reverse osmosis membrane, and the other end is the pure water outlet of the second water purification reverse osmosis membrane.
