In order that those skilled in the art more fully understand the present invention program, with reference toAccompanying drawingThe present invention is described in further detail with specific embodiment.
Refer toFigure 2, shouldDiagramThe winding pre-structure having gone out RO film vortex cell (only containing one group of doubling RO pair of pages film group) specific embodiment is illustratedFigure.
ByFigureUnderstand, RO film vortex cell includes central water tube 1 and the RO membrane module being wound in this central water tube 1, wherein, under deployed condition, RO membrane module includes 3, the two RO single page diaphragms 7 of pure water flow-guiding cloth stacking and one group of doubling RO pair of pages film group being located between two RO single page diaphragms 7, doubling RO pair of pages film group includes doubling RO pair of pages diaphragm 2 and clamping pure water flow-guiding cloth 3 in the inner, is provided with concentrated water flow-guiding screen 4 between doubling RO pair of pages diaphragm 2 and RO single page diaphragm 7.
The concentrated water side of both RO single page diaphragm 7 and doubling RO pair of pages diaphragm 2 is all tightly connected along coiling direction with concentrated water flow-guiding screen 4, with the concentrated water runner being formed along coiling direction extension and connect with central water tube 1, both pure water sides are all tightly connected the pure water runner being formed along the axial one-way flow of central water tube 1 with pure water flow-guiding cloth 3.
Doubling RO pair of pages diaphragm 22 is that center along its length is folded to form by whole rectangle RO single page diaphragm 7.
Central water tube 1 perisporium offers multiple water holes, and, one port blocks, and another port is opened wide, and each water hole connects with the port opened wide, and water hole is connected concentrated stream with central water tube 1 all.
Next, combiningFigure 3Manufacture method above-mentioned RO film vortex cell to be described, shouldDiagramGo out only to contain the manufacture method technological process of the RO film vortex cell of one group of doubling RO pair of pages film groupFigure.
The manufacture method of above-mentioned RO film vortex cell comprises the steps:
S00, make RO membrane module, RO membrane module includes the pure water flow-guiding cloth 3 stacking successively, two RO single page diaphragms 7 and the least one set doubling RO pair of pages film group being located between two RO single page diaphragms 7, doubling RO pair of pages film group includes doubling RO pair of pages diaphragm 2 and clamping pure water flow-guiding cloth 3 in the inner, it is provided with concentrated water flow-guiding screen 4 between doubling RO pair of pages diaphragm 2 and single page diaphragm, after stacking period or stacking, along perpendicular to doubling RO pair of pages diaphragm 2 broken line direction, by concentrated water flow-guiding screen 4, the one respective side gluing of RO single page diaphragm 7 and doubling RO pair of pages diaphragm 2 three is tightly connected.
Specifically, first, pure water flow-guiding cloth 3 is wound around 2~3 circles in central water tube 1, then RO single page diaphragm 7 is stacked in above pure water flow-guiding cloth 3, pure water flow-guiding cloth 3 is close in RO single page diaphragm 7 pure water side;
Secondly, concentrated water flow-guiding cloth is stacked in above RO single page diaphragm 7, then along perpendicular to central water tube 1 axis direction, concentrated water flow-guiding screen 4 and RO single page diaphragm 7 concentrated water side one respective side gluing is tightly connected;
Again, a RO single page diaphragm doubling (pure water side is internally) is formed doubling RO pair of pages diaphragm 2, then fold up pure water flow-guiding cloth 3 in the middle of doubling RO pair of pages diaphragm 2, and so that pure water flow-guiding screen one end is overlapped with diaphragm fold position;
Then, concentrated water flow-guiding cloth is stacked in above doubling RO pair of pages diaphragm 2, then along perpendicular to central water tube 1 axis direction, concentrated water flow-guiding screen 4 and doubling RO pair of pages diaphragm 2 concentrated water side one respective side gluing is tightly connected;
Finally, another RO single page diaphragm 7 is stacked in above concentrated water flow-guiding cloth, then along perpendicular to central water tube 1 axis direction, concentrated water flow-guiding screen 4 and doubling RO pair of pages diaphragm 2 concentrated water side one respective side gluing is tightly connected.
S10, with the broken line of doubling RO pair of pages diaphragm 2 for wind initiating terminal, RO membrane module is wound in central water tube 1, the corresponding sides then pure water flow-guiding cloth 3, doubling RO pair of pages diaphragm 2 and RO single page diaphragm 7 three being wound clearing end are tightly connected along central water tube 1 axis direction gluing;
S20, by RO single page diaphragm 7, doubling RO pair of pages diaphragm 2, concentrated water flow-guiding screen 4 and pure water flow-guiding cloth 3, another respective side entirety gluing along coiling direction is tightly connected, the concentrated water runner being extended along coiling direction with being formed and connect with central water tube 1 and along the axial unidirectionally extended pure water runner of central water tube 1.
It should be noted that, in above-mentioned manufacture method, RO single page diaphragm 7, doubling RO pair of pages diaphragm 2 and the triangular gluing of concentrated water flow-guiding screen 4 are tightly connected is to implement one by one during stacking, it is appreciated that, it is tightly connected on the basis of function and processing technique require between three meeting, gluing is tightly connected step and also can implement one by one after the completion of stacking successively again.
Step S11 is may also include between step S10 of above-mentioned manufacture method and S20:
The periphery of S11, after the coiling RO film vortex cell semi-finished product is wound around at least one circle adhesive tape and fixes.
So, after can preventing winding, RO film vortex cell semi-finished product become loose in subsequent step S30 and affect its filter efficiency.
Because the water inlet of RO film vortex cell is the axial gap along central water tube 1 axis that doubling RO pair of pages diaphragm 2 and concentrated water flow-guiding screen 4 wind clearing end, therefore, in order to ensure that RO film vortex cell possesses larger flux, after step S20, also include S30, to remove the adhesive tape introducing in S11 step.
S30, last, remove the adhesive tape being wound in RO film vortex cell periphery wall.
Further, in order to prevent two diaphragms of doubling RO pair of pages diaphragm 2 inter-adhesive in winding process,As figure 2Shown, along along coiling direction, pure water flow-guiding cloth 3 and concentrated water flow-guiding screen 4 are concordant or stretch out by the edge of two diaphragms of doubling RO pair of pages diaphragm 2, so that page two diaphragms of isolation doubling RO pair of pages diaphragm 2.
This RO film vortex cell, the axial gap of clearing end is wound as water inlet with doubling RO pair of pages diaphragm 2 and concentrated water flow-guiding screen 4, tap water flows into concentrated water runner by water inlet under external pressure, then flow into behind stream of pure water road via formation pure water after RO membrane filtration, the pure water mouth being formed between being guided to by doubling 2 two diaphragms of RO pair of pages diaphragm by pure water flow-guiding cloth 3;Meanwhile, the concentrated water being formed after filtration then continues to reach after central water tube 1 periphery wall along concentrated water runner, and the multiple water holes via central water tube 1 periphery wall flow in central water tube 1, are finally discharged by central water tube 1.
Additionally, gluing sealing in first local in this RO film vortex cell manufacturing process, again processing technique is simplified to the mode of overall gluing sealing after winding, improve manufacture efficiency.
Because above-mentioned RO film vortex cell includes multiple assemblies of stacking setting successively, if winding initiating terminal is concordantly arranged after multiple assemblies stack, the RO film vortex cell finished product being formed after winding will form noticeable steps and be in non-circular shape in winding starting point, so do not only take up larger installing space, but also cavity can be formed at step and there is hydrops problem.
For this reason, along overlay order, pure water flow-guiding cloth 3, the winding initiating terminal of concentrated water flow-guiding screen 4, RO single page diaphragm 7 and doubling RO pair of pages diaphragm 2 are successively wound in described central water tube 1 successively.
Specifically manufacture method is:
In step S00, along overlay order, pure water flow-guiding cloth 3, concentrated water flow-guiding screen 4, RO single page diaphragm 7 and doubling RO pair of pages film group are along away from winding initial extreme direction translation preset distance.
Further, if in step 10, before the superiors RO single page diaphragm 7 contact central water tube 1, RO membrane module winding center water pipe 1 one weeks, the concentrated water passage of so the superiors RO single page diaphragm 7 cannot directly be connected with central water tube 1, but needs to be connected with central water tube 1 after adjacent concentrated water passage again, when so bring a drawback rinses diaphragm, can excessively be concentrated due to passage, flushing strength not, cause diaphragm to be difficult to rinse well.
For this reason, when the application RO film vortex cell makes, step S00 limits the superiors RO single page diaphragm 7 and orlop RO single page diaphragm 7 translation distance away from winding initiating terminal further.
In detail, the superiors RO single page diaphragm 7 is less than or equal to the girth of central water tube 1 periphery wall with respect to orlop RO single page diaphragm 7 along the translation distance away from the initial extreme direction of winding, thus solving above-mentioned technical problem it is ensured that flush efficiency.
In addition, tensile force due to RO membrane module winding center water pipe 1 is mainly provided by orlop pure water flow-guiding cloth 3, in the application in step S00, before RO membrane module winding center water pipe 1, orlop pure water flow-guiding cloth 3 pre-wound central water tube 1 at least one encloses, thus ensure that the laminating tight type of each inter-module RO membrane module Nei.
Above-mentioned RO film vortex cell only includes one group of doubling RO pair of pages film group, and in order to obtain bigger flux, the quantity of doubling RO pair of pages film group A can be two or more sets.
Next, combiningFigure 4Concrete structure of RO film vortex cell containing three groups of doubling RO pair of pages film groups and preparation method thereof to be described.
It should be noted that, single group doubling RO pair of pages film group is identical with the RO film vortex cell principle of three groups of doubling RO pair of pages film groups, those skilled in the art can directly cut beyond all doubt knowing completely based on foregoing description, so for simplicity of exposition, only being described in detail to both differences below.
ByFigure 4Understand, three groups of doubling RO pair of pages film groups stack successively, the manufacturing process of doubling RO pair of pages film group is identical with the manufacturing process of aforementioned single group doubling RO pair of pages film group, only need in repeat step 00 by a RO single page diaphragm 7 doubling (pure water side is internally) formed doubling RO pair of pages diaphragm 2, fold up pure water flow-guiding cloth 3 in the middle of doubling RO pair of pages diaphragm 2 again, and so that pure water flow-guiding screen one end is overlapped with diaphragm fold position.
Then stack successively and in two neighboring doubling RO pair of pages membrane module placement concentrated water flow-guiding screen 4 in three groups of doubling RO pair of pages film groups, again along perpendicular to doubling RO pair of pages diaphragm 2 broken line direction, concentrated water flow-guiding screen 4 and doubling RO pair of pages diaphragm 2 concentrated water side one respective side gluing are tightly connected, finally continue implementation steps 10 and step 20 can complete the RO film vortex cell containing three groups of doubling RO pair of pages film groups.
Compared with the RO film vortex cell of the aforementioned RO pair of pages film group of doubling containing single group, the RO film vortex cell containing three groups of doubling RO pair of pages film groups A can form three concentrated water runners and three pure water runners, and flux is big, filter efficiency is high.
It is appreciated that, compared with the RO film vortex cell of the aforementioned RO pair of pages film group of doubling containing single group, with increasing of doubling RO pair of pages film group A quantity, if winding initiating terminal is concordantly arranged after multigroup doubling RO pair of pages film group stacks, the RO film vortex cell finished product being formed after winding will form in winding starting point and become apparent from step and be in non-circular shape, it will take larger installing space.Additionally, also bigger cavity being formed at step and making hydrops problem more serious.
For this reason, in second specific embodiment, three groups of doubling RO pair of pages film groups A are launched under superposed state, the winding initiating terminal of last layer doubling RO pair of pages film group A and the winding initiating terminal of next layer of doubling RO pair of pages film group A have preset distance.
Specifically, in two neighboring doubling RO pair of pages film group in step S00, last layer doubling RO pair of pages film group, with respect to next layer of doubling RO pair of pages film group, translates preset distance along away from the initial extreme direction of winding.
It is arranged such, on the one hand the winding initiating terminal that three groups of doubling RO pair of pages film groups A can be made successively is wound on central water tube 1 periphery wall successively, thus winding each winding initiating terminal of initial stage to be sequentially overlapped formation smooth surface, follow-up winding can be close to this smooth surface section, make RO film vortex cell finished form tend to circular, take installing space less;On the other hand, also cavity can be avoided the formation of it is therefore prevented that hydrops problem in cavity.
Further,As figure 5Shown, in another concrete mode of the present invention, RO film vortex cell also includes upper end cover 5 and bottom end cover 6, wherein, upper end cover 5 is fixedly connected on the one end of central water tube 1 and offers central water tube 1 through hole and pure water outlet, the outlet of its pure water and pure water flow passage, the concentrated water water side of central water tube 1 passes through installing hole and is tightly connected therewith, and bottom end cover 6 sealing is fixed on the other end of central water tube 1.
Last it is emphasized that, this RO film vortex cell Making programme is simple, improve the effective rate of utilization of diaphragm, reduce RO membrane material cost;Pure water flow passage resistance force of waterproof less (pure water flow channel length be only along central canal axial direction flowing), faster (concentrated water has to pass through the runner of whole concentrated water flow-guiding screen length to concentrated water runner flow velocity, other concentrated water runners, because some opening is used for water inlet or water outlet, necessarily lead to concentrated water runner to be shorter than concentrated water flow-guiding screen length).
The foregoing is only the preferred embodiment of the present invention, do not constitute limiting the scope of the present invention.Any any modification, equivalent and improvement made within the spirit and principles in the present invention etc., should be included within the claims of the present invention.
