Description
Technical field
This utility model belongs to the cleaning field in doughnut preparation process, especially relates to a kind of hollow
Fiber spinning jet or cleaning device for spinning plate.
Background technology
In recent years, along with increasingly sharpening of shortage of fresh water problem and constantly adding of law enforcement for environmental protection dynamics
By force, advanced treating and the reuse technology i.e. membrance separation of sewage has obtained quickly sending out under existing technical conditions
Open up and have been applied in various fields.Membrane technology, as a kind of physical separating process, is not required to phase
Change and interpolation auxiliary agent.Therefore have processed object active component loss little, operation operation energy consumption low,
Contamination of products degree is little, to processing selectivity height, the strong adaptability of object, being prone to the advantages such as automatization.
Hollow-fibre membrane because the loading density in its unit volume is relatively big, need not any supporter, be easily achieved
Back flush, compact to design, can tolerate high-concentration colloid and the enterprise that enjoys film to produce and the favor of user.
Current business-like doughnut uses phase inversion to prepare mostly, namely homogeneous by one
Macromolecule casting solution make macromolecule precipitating from homogeneous phase solution out, be allowed to be divided into two by all means
Phase, one is macromolecule richness phase, forms the network structure of film；Another is that macromolecule is stingy, forms fenestra.
For hollow-fibre membrane, phase separation is to occur from inner side or chamber and shell-side or outside simultaneously, and be from
Brace type, so fiber dimensious is particularly significant.
During dry and wet spinning, the specification of spinning head or spinneret is particularly significant, because fiber dimensious master
To be determined by spinning head or spinneret size.After entering coagulation bath, fiber dimensious is the most constant.Molten
During warm dry-spinning, fiber dimensious depends primarily on rate of extrusion and pulling speed, by spinning head specification
Impact less.
The at present spinning head of hollow-fibre membrane production process or the core liquid pipe of spinneret and the casting film of spinning head
Liquid path clearance is less, because using misoperation or working condition to control not conform in actual operating process
The reason such as suitable cause the casting solution path clearance of spinning head or spinneret or tiny core liquid channel part or
Person all blocks, thus causes the doughnut specification of preparation and size to have greatly changed, and causes raw
Product process stops affecting the stability of production process and product quality.
The method conventional for the restoration methods of existing be blocked spinning head or spinneret mainly includes two:
(1) will be blocked spinning head or spinneret in a certain order it is successively taken apart after clear up；
The advantage of the method is can to obtain spinning head or the spinneret of dredging in the short period of time；Defect
It is that, owing to spinning head or spinneret belong to polish parts, its assembling all has certain technology requirement, separately
Extenal fixation core liquid Guan Yin on base is compared with thin and intensity is relatively poor, and the process assembled after cleaning is relatively held
Yielding, need specialty and relatively those skilled in the art to assemble, and the spray webbing after ressembling
Core liquid pipe and the concentricity of casting solution passage of head or spinneret is relative to the more difficult recovery in position extremely original essence
Degree；(2) spinning head being blocked or spinneret are put in solvent and by solvent, gel or part are coagulated
The method that the casting solution of glue gradually dissolves dredges casting solution or core liquid passage, and the advantage of the method is permissible
Ensureing original spinning head or the precision of spinneret assembling, reduce the various problems that dismounting causes, shortcoming is
This progressively course of dissolution to be that a natural process needs time-consumingly the longest, should in the case of relative in order to ensure to produce
Standby more spinning head or spinneret continuously, is stably then needed to maintain original production efficiency, but generally
In the case of solvent can also be heated to promote dissolution velocity, the cleaning improving spinning head or spinneret is imitated
Rate.The advantage of two kinds of common methods is all being focused on a device by this utility model patent, overcomes existing
There are technological difficulties present in hollow fiber spinneret or spinneret cleaning process, and then improve the life of enterprise
Produce efficiency and the stability of product quality.
