Description
Technical field
The utility model relates to the special dies that a kind of milipore filter is produced, particularly a kind of spinneret of production enhancement mode hollow-fibre membrane.
Background technology
Hollow-fibre membrane is a kind of as the diffusion barrier form, because it has good pressure-resistant performance, need not supporter, membrane module can be made any size and shape, and the loading density in membrane module is big, advantages such as the membrane area of unit volume is big, flux is big are widely used in the every field that film separates.But,, make that the hot strength of hollow-fibre membrane is very low, and can not under the situation of hypertonia, use because the manufacturing process imperfection of internal membrane, the film silk intensity produced are not high.The at present domestic spinneret that inserts tubular type single hole spinning head that generally adopts is made the single hole hollow-fibre membrane, lower and the wall unevenness of single hole hollow-fibre membrane compressive resistance that produces, also cause the doughnut membrane separating effect to descend easily, in addition, have on material and spinning condition and improved the practice for preparing the enhancement mode hollow-fibre membrane, but often make the spinning technique relative complex that becomes, be difficult to control, also increased financial cost to a certain extent.Yet there are no the relevant report that adopts three holes or multi-holed jet to make three holes or many emptying apertures hollow-fibre membrane.
Summary of the invention
The utility model purpose is to provide a kind of spinneret that can produce three holes or porous hollow fiber membrane, makes the enhancement mode hollow-fibre membrane of producing that higher voltage endurance capability and uniform wall thickness be arranged, and can simplify spinning technique.
For achieving the above object, the utility model adopts following technical scheme: this spinneret is made up of a cover plate, a base plate, and cover plate and base plate pass through bolting.
(1) base plate:
1. there is a material cave at the center, accepts the feed liquid that the supplied materials pipe flows down, and there is an inner-intubation spinneret orifice in the outside, material cave; Link together by a rectangle-semicircle feed liquid passage between material cave and the spinneret orifice.
2. spinneret orifice is made up of guide hole and spray silk micropore, and the cross sectional shape of spray silk micropore is circular or special-shaped, and the guide hole vertical sectional shape is trapezoidal.A spray silk micropore cross sectional shape is that abnormity can be trilobal or quatrefoil or five leaf etc.
(2) cover plate:
1. the center has one to be connected with the supplied materials pipe and to have a feed liquid through hole of internal thread, and feed liquid through hole lower end but the relative less and threadless feed liquid through hole of diameter coaxial with this through hole with links to each other.
2. cover plate one side has a core liquid duct, it is designed to three or more core liquid duct and is fixed on the cup dolly with base plate guide hole opposite position, and the cross sectional shape of single core liquid duct is circular, and three or more core liquid duct is and is evenly distributed.
The internal thread core fluid through-hole that 3. connection-core liquid conveying and metering pump is arranged on the close side of core liquid duct; Link to each other by core liquid passage between internal thread core fluid through-hole and the three hole core liquid ducts.
The utility model advantage is: the core liquid duct on this spinneret cover plate is improved, it is designed to three or more core liquid duct by single core liquid duct, make the same hollow-fibre membrane of producing be three holes or porous, so both simplified spinning technique, improved the voltage endurance capability of film again, make that the hollow-fibre membrane in the submerged membrane assembly can bear higher hot strength and pressure reduction in the vacuum draw process, fracture can not appear in the process of swing, thereby strengthened the stain resistance of doughnut greatly, no longer need regular backwash, can improve its disposal ability again, not only reduced operating cost like this, and the yield of water is greatly improved, and has development prospect preferably.

The specific embodiment
In order more clearly to understand technology contents of the present utility model, lift following example and also be elaborated in conjunction with the accompanying drawings.
With reference to accompanying drawing 1-7, the utility model spinneret is made up of base plate (feed liquid plate) 1 and cover plate (core liquid plate) 6, and is fixing by bolt and internal thread bolt hole 7.In the middle of base plate 1 top material cave 2 is arranged, one inner-intubation pinning hole 4 and micropore 5 are arranged, link together by a rectangle-semicircle feed liquid passage 3 between material cave 2 and the pinning hole 4 in the one side; Cover plate 6 centers have one to be connected with the supplied materials pipe and to have a feed liquid through hole 8 of internal thread, and feed liquid through hole 8 lower ends but diameter relative less and threadless feed liquid through hole 9 coaxial with this through hole with links to each other; Cover plate 6 sprays on the silk micropore 5 corresponding positions with base plate is fixing a cup dolly 10, be uniform-distribution with three core liquid ducts 11 above, insert spray silk micropore 5 in three core liquid ducts 11,11 are fixed on the circle three hole core liquid duct bases 10 that link to each other with cover plate 6, near the internal thread core fluid through-hole 13 that connection-core liquid conveying and metering pump is arranged on the side of core liquid duct, link to each other by core liquid passage 12 between internal thread core fluid through-hole 13 and the three hole core liquid ducts 11; Its spray silk pore cross sectional shape is circle or trilobal.
Feed liquid enters no screw thread feed liquid through hole 9 from the supplied materials pipe through cover plate 6 internal thread feed liquid through holes 8, flows into pinning hole 4 via base plate material cave 2 and rectangle-semicircle feed liquid passage 3 then, at last by 5 ejections of spray silk micropore; Core liquid enters three hole core liquid ducts 11 by inside spin core fluid through-hole 13 via core liquid passage 12 by core liquid conveying and metering pump, form three strands of core liquid, contact with the feed liquid that sprays from spray silk micropore 5 when core liquid flows out, thereby make the nascent state fiber form hollow, inject the coagulation bath freezing film then.The same hollow-fibre membrane that produces like this has three holes, both improved film strength, saved raw material, reduced the influence of eccentric shape to the film handling property again.
Accompanying drawing 8-11 is the utility model base plate and the cover plate profile vertical view when being rectangle and triangle, and its structure, operation principle are with embodiment 1.
