Description
Technical field
The utility model is related to spinneret field, in particular it relates to novel porous spinning head.
Background technology
Hollow-fibre membrane is outer image threadiness, the film with self-supporting effect, be applied to environmentally friendly water process, Hemodialysis,
In the industries such as air separation membrane, liquid separating film, desalinization.Hollow tunica fibrosa spinneret is for producing hollow-fibre membrane
Mould.Hollow-fibre membrane is the core of the field devices such as water process, Hemodialysis, desalinization, gas separation, liquid separation
Part, is applied to reverse osmosis membrane, microfiltration membranes, a kind of important new material of the aspect such as NF membrane and milipore filter, in environmentally friendly water process, blood
The fields such as dialysis, gas separation are gradually increasingly widely applied.With quality and performance requirement to hollow-fibre membrane
Raising, the increase of demand, domestic existing production technology and equipment is increasingly difficult to meet Production requirement, and major part is relied on
Import.
High-performance hollow tunica fibrosa and improve production efficiency are how produced, production cost is reduced, it has also become in research
Hollow fiber film field is most popular, be also one of problem of most critical.The production forming process of hollow-fibre membrane, simplified summary is just
It is that spinning liquid and core liquid are injected into spinning head from the diverse location of spinning head pedestal, by the special construction inside spinning head,
The thread thing of doughnut-be commonly called as film silk is sprayed from spinneret skull.From the point of view of whole film-forming process, except membrane equipment and technique are joined
Number is affected outside film silk performance, and the quality of spinning head directly influences some key performances and parameter of film silk.Therefore, to be closed
The hollow fiber film thread of suitable size, outward appearance and function admirable, the nozzle design of high-quality is top priority.
Generally hollow fiber film major part of the prior art uses single hole spinning head, each during single hole spinning head spinning
A silk can only be gone out, production efficiency is extremely low, it is impossible to which scale is produced in a large number.
Although there is also multi-holed jet in prior art, these multi-holed jets are it is impossible to ensure that enter into each core
The core liquid of liquid pipe or/and the feed liquid into each spinneret orifice keep identical pressure and uniformity, thus also affect product quality
Stability and uniformity.Such as CN204570108U, CN101372765A.
In some multi-holed jets, it is directed to each spinneret orifice and independent spinneret is set, although so can be respectively
Adjust the concentricity of the corresponding core liquid pipe of spinneret orifice to ensure the uniformity of the thickness of film silk, improve quality, but operation
It is excessively loaded down with trivial details, and, this kind of spinning head, even if regulating, using a period of time after, still can produce that film silk has can be inclined
The heart, must readjust again.It is envisioned that if hundreds of hole, thousand of holes always need to be adjusted every a period of time
Whole, workload has much, and this is significant adverse to large-scale production.Such as CN101372765A, CN204803446U.
In some multi-holed jets, core liquid pipe is fixed design, so in case of indivedual core liquid pipes are blocked or are damaged, it is necessary to
Change together with feed liquid, the input of core liquid and storage part, waste greatly and change and be inconvenient.Such as patent
CN204803446U。
