Description
Technical field
The utility model relates to a kind of duplexer that filters the hollow-fibre membrane braid of usefulness, and the duplexer of this hollow-fibre membrane braid is suitable for making employed hollow fiber film assembly in the various sedimeters such as water purifier.
Background technology
Employed hollow fiber film assembly is as shown in Figure 1 in the sedimeters such as water purifier.Wherein Fig. 1 (A) is the fixing hollow fiber film assembly of bilateral resin, and Fig. 1 (B) is the fixing hollow fiber film assembly of one-sided resin.In the past, when making this hollow fiber film assembly, generally hollow-fibre membrane was cut to specific length and was accommodated in resin fixing, and with epoxy resin or polyurethane resin etc. the end of hollow-fibre membrane was fixed on resin then and fixes with in the container with in the container.Yet, if the peristome of hollow-fibre membrane end is kept open state and fixes, fixingly may enter into hollow-fibre membrane inside from this peristome with resin, cause the inner obstruction of hollow-fibre membrane and can't play the effect of filtration.For fear of this problem; Adopt following method: with resin the end of hollow-fibre membrane is sealed temporarily in advance; Under this state, fix again, standing part is cut off after fixing and make the end of hollow-fibre membrane become open state (this hollow fiber film assembly and manufacturing approach thereof see TOHKEMY 2009-018283 communique for details).
Yet in said method, have following problem: interim enclosure portion goes out of use after hollow fiber film assembly is accomplished, and interim closing step can cause the increase of Master Cost and processing charges; And when sealing, can't judge whether this interim sealing is carried out effectively temporarily, only after the hollow fiber film assembly manufacturing is accomplished, could judge through the section of observing fixed part whether interim sealing is good; In addition; When interim sealing is not good; The fixing entering with resin sealed the inside of not good hollow-fibre membrane temporarily and stopped up this hollow-fibre membrane, causes hollow fiber film assembly can't guarantee the membrane area of stipulating, not at all easy sometimes hollow fiber film assembly of making but becomes waste product.
In addition; Fixing in order hollow-fibre membrane to be accommodated in resin with in the container; Need it be put together neatly, otherwise that the hollow-fibre membrane of peripheral part can become is in disorder, wherein the end of some hollow-fibre membrane fixing imbedded in resin shallow; Can't make it become open state through the cut-out of standing part; Such hollow-fibre membrane can't be used in the process of filtering effectively, and the end of some hollow-fibre membrane may omit fixing with resin outside, such hollow-fibre membrane causes the leakage of water purification in the process of filtration.
In order to address the above problem; The utility model applicant proposed a kind of braid (japanese kokai publication sho 62-057965) of hollow-fibre membrane; Wherein, As shown in Figure 2, hollow-fibre membrane is not turned back to the other end from an end of the width of braid with not being cut off continuously, compiles braiding at the two ends of width through the lock of warp and is held.In a slice hollow-fibre membrane braid that forms like this; The openend of hollow-fibre membrane has only two; So do not need interim sealing in the mill during the hollow fiber membrane module, and owing to adopting the longitude and latitude braiding to make the arrangement of hollow-fibre membrane roughly neat, thereby can carry out reliable fixation.
But; When forming the hollow fiber film assembly of rectangle, the thickness of the above-mentioned hollow-fibre membrane braid of a slice is often not enough, at this moment; Usually take following method: according to the lengths needed of the range upon range of body of hollow-fibre membrane braid; Weave a slice to such an extent that long hollow-fibre membrane braid broad ways is cut off, form multi-disc hollow-fibre membrane braid, these multi-disc hollow-fibre membrane braids are laminated to each other together and form the duplexer of the hollow-fibre membrane braid of rectangle; Perhaps do not weave to such an extent that long hollow-fibre membrane braid cuts off, and it is directly folded, through being folded to form the range upon range of body of hollow-fibre membrane braid above-mentioned.If adopt to cut off the range upon range of method in back, not only need cut off operation and lose time, and when cutting off near the hollow-fibre membrane the damage cut-off part easily, the water purification when causing purifying waste water leaks; If employing is not cut off directly folding method then can be avoided the problems referred to above; If but the thickness of hollow-fibre membrane braid is thicker; Then near the hollow-fibre membrane the burst interferes with each other on diametric(al), is difficult to carry out neat folding, and the outward appearance of the duplexer of hollow-fibre membrane braid is not good; And to resin is fixing when installing with container, operability is variation also with it in the back.

The specific embodiment
Below, specify the preferred implementation of the utility model with reference to accompanying drawing.
Fig. 3 is the sketch map of the structure of the related hollow-fibre membrane braid of expression the utility model.In Fig. 3, direction X representes the width of hollow-fibre membrane braid, and direction Y representes the length direction of hollow-fibre membrane braid.This hollow-fibre membrane braid has: hollow-fibre membrane 1, its on the width of this hollow-fibre membrane braid from the end of a side of this hollow-fibre membrane braid to the end of opposite side continuously the snake shape turn back, form the multirow parallel; And warp 2,2 ', 3,3 ', it is arranged on the end of both sides of the width of this hollow-fibre membrane braid, and extends along the length direction of this hollow-fibre membrane braid.And; This hollow-fibre membrane braid comprises: warp 2,2 ', 3,3 ' is woven in a plurality of knitted parts A on every capable parallel and does not comprise at least one capable gap part B of parallel, and a plurality of knitted parts A and at least one gap part B alternately arrange on the length direction of this hollow-fibre membrane braid each other singly.This hollow-fibre membrane braid bends at gap part B, thereby forms the duplexer of the range upon range of hollow-fibre membrane braid shown in Figure 4 of knitted parts A.Fig. 4 is the sketch map that the duplexer of doughnut film braid is seen in end that the end from a side of the width of the duplexer of hollow-fibre membrane braid promptly is provided with a side of warp (for example warp 2).In Fig. 4; Shown in the frame of broken lines be warp 2,2 ' not with the gap part B of hollow-fibre membrane 1 braiding; In addition; In fact the situation of just having represented three knitted parts A of stacked on top of one another among Fig. 4 for example, can process the duplexer that thickness satisfies the hollow-fibre membrane braid of use needs by range upon range of a plurality of knitted parts A.
Warp for gap part B place; Though shown in Figure 3, hollow-fibre membrane 1 in one side of this warp walking and not with its braiding, this warp preferably self continues braiding; So; When cutting off at gap part B place if desired, because the structure that the warp is here woven, therefore be not easy to take place the line that splits of parallel.
In hollow-fibre membrane braid shown in Figure 3; End in the both sides of its width respectively is provided with two warps 2,2 ' and 3,3 '; But as long as the quantity of warp can make this hollow-fibre membrane braid keep definite shape when installing with container and do not scatter to resin is fixing in the back; For example; Can be shown in Fig. 5 (A), in the end of the both sides of the width of hollow-fibre membrane braid a warp only is set respectively, also can as on the width of Fig. 5 (B) this hollow-fibre membrane braid that is shown in so that many warps uniformly-spaced to be set.
In addition, the end of the both sides of above-mentioned width at the hollow-fibre membrane braid situation that warp all is set is applicable to the hollow fiber film assembly that the bilateral resin made as Fig. 1 (A) shown in is fixed.When hollow fiber film assembly that the one-sided resin that is used for making as Fig. 1 (B) shown in is fixed; Also can be only warp be set in the end of the resin fixation side of this hollow-fibre membrane braid; In the case; The parallel line number of the knitted parts of above-mentioned warp and parallel braiding is preferably even number line, like this, and in whole hollow-fibre membrane braid; Two peristomes of hollow-fibre membrane are positioned at the same side of braid width all the time, and it is fixing with getting final product in the container that this side is installed in resin as the resin fixation side.On the contrary; If said parallel line number is an odd number; Then two of hollow-fibre membrane peristomes possibly be positioned at the opposite both sides of braid width, and when making the fixing hollow fiber film assembly of one-sided resin, the hollow-fibre membrane that just has a side produces and leaks so.
Certainly; Keep comparatively fixed shape in order to make the hollow-fibre membrane braid; Thereby the hollow-fibre membrane braid folding process that makes the back with folding after duplexer be more prone to for the fixing fitting operation of resin with container; Therefore, even also can use the range upon range of body of hollow-fibre membrane braid that warp all is set in the end of the both sides of the width of hollow-fibre membrane braid for the fixing hollow fiber film assembly of one-sided resin.In this case; Preferably the warp of the both sides of the width of hollow-fibre membrane braid is made various colors; So that a side of hollow-fibre membrane opening to be arranged in the above-mentioned both sides of mark, like this, when the hollow fiber film assembly that the one-sided resin of manufacturing is fixed; The operator is the side with hollow-fibre membrane opening of distinguishable hollow-fibre membrane braid according to the color of both sides warp, it is installed to resin as the resin fixation side fixes with in the container.
In Fig. 3; Line number with knitted parts A is that 4 hollow-fibre membrane braids capable, that the shared line number of gap part B is 3 row are that example is represented; In Fig. 4, be that the duplexer of 3 layers hollow-fibre membrane braid is that example is represented with the number of plies, but in fact, according to the dimensional requirement of hollow fiber film assembly; The line number of knitted parts A is far longer than 4 row usually; And at gap part B place during folding hollow-fibre membrane, the hollow-fibre membrane 1 neighbouring with gap part B do not produce interference each other, and the length of gap part B is greater than the diameter that equals doughnut.Can carry out various selections to the line number of knitted parts A, the length of gap part B, the number of plies of the range upon range of body of hollow-fibre membrane braid according to the shape and size of the hollow-fibre membrane braid that will make and the performance of braider.
And; If make the range upon range of body of hollow-fibre membrane braid of rectangle; Then the braiding line number of a plurality of knitted parts A of hollow-fibre membrane braid is equal to each other, and for the ease of when weaving, braider being controlled, the length of above-mentioned gap part B preferably also equates.In addition, in order to enhance productivity, continuous weaving goes out to have the long hollow-fibre membrane braid of said structure in advance; It is subsequent use as material bodies, aborning during the range upon range of body of hollow fiber film braid, according to the needs of the shape and size of the range upon range of body of hollow-fibre membrane braid; Width along this material bodies; At gap part B place, cut out the hollow-fibre membrane braid monomer of Len req down from this material bodies, for example; In the example of the range upon range of body of hollow-fibre membrane braid shown in Figure 4, the hollow-fibre membrane braid monomer (with reference to figure 3) that is used to make this duplexer has 3 knitted parts A and 2 gap part B.Then,, bend, form the duplexer that the number of plies as shown in Figure 4 is 3 layers a hollow-fibre membrane braid at gap part B place for each hollow-fibre membrane braid monomer.
If the hollow-fibre membrane braid is made into by braider; Then the material for hollow-fibre membrane does not have specific (special) requirements, and the material of hollow-fibre membrane mainly contains vistanexes such as polyvinyl resin or acrylic resin, polysulfone resin, polyethersulfone resin, sulfonated polysulfone resin, polyvinylidene fluoride resin, polyacrylonitrile resin, polyimide resin, polyamide-imide resin or polyesterimide resin etc.As warp; Adopt the warp of general braid to get final product; But consider when the hollow-fibre membrane braid made or operate and do not damage hollow-fibre membrane, preferably adopt the low line of hardness such as spinning line as warp, and the tension force of warp is more little good more when braiding.
