Description

A kind of hollow pricker dimension film spinning head of novel lining-reinforced

Technical field

The utility model relates to field of sewage treatment equipment, and in particular to a kind of hollow pricker dimension film of novel lining-reinforced Spinning head.

Background technique

Hollow-fibre membrane is the core component of water treatment facilities, is applied to reverse osmosis membrane, microfiltration membranes, nanofiltration membrane and ultrafiltration membrane Etc. a kind of important new material, gradually had been more and more widely used in fields such as environmentally friendly water process.With to hollow The quality of tunica fibrosa and the raising of performance requirement, wherein film-strength even improves film due to being directly related to the service life of film Flux and processing capacity, thus seem particularly significant.Therefore, lining-reinforced hollow-fibre membrane comes into being, and is widely applied On curtain type film assembly in membrane reactor.How to produce high performance lining-reinforced hollow-fibre membrane and improves life Efficiency is produced, production cost is reduced, it has also become one of the problem of research field is most popular and most critical.The life of hollow-fibre membrane Forming process is produced, simplified summary is exactly that spinning liquid is injected spinning head from the different location of spinning head pedestal, passes through spinneret Special construction inside head sprays hollow fiber film thread from spinneret skull；And lining-reinforced hollow-fibre membrane is then practical The materials such as woven tube form hollow fiber film thread as enhancing liner, by coating spinning on it.Come from entire film-forming process It sees, in addition to membrane equipment and effects of process parameters film wire performance, the superiority and inferiority of spinning head directly influences some key of film wire Energy and parameter.Therefore, the hollow fiber film thread of suitable dimension, appearance and function admirable, good nozzle design teacher to be obtained Top priority.The film-strength of the hollow pricker dimension film spinnerette of the lining-reinforced of the prior art can not enough be broken；Such as patent is awarded The Chinese utility model patent of power notification number CN206127497UD discloses a kind of hollow pricker dimension film spinning head of lining-reinforced It is characterized by comprising three casing cover board, central jets body and spray head sleeve parts to form；Wherein, most basic is the spray Headgear cylinder, middle layer are the central jets body, and top layer is described sleeve pipe cover board；The central jets body and spray head sleeve group Conjunction forms liquid feed chamber, and the central jets body and casing cover plate combination form pre-invasion chamber；The pre-invasion is intracavitary to be equipped with liner Enhancement type hollow fiber film；Spray head sleeve two sides aperture；Two side opening of central jets body.The patent is sprayed by center Head and spray head sleeve combination form liquid feed chamber, and the mode that central jets body and casing cover plate combination form pre-invasion chamber is carried out to volume Tubulation is coated, but does not disclose the technical characteristic and its technical principle of pre-invasion chamber in detail in this Patent Case, Therefore there are following technical problems: one, film liquid is to be coated in the outer surface of woven tube, without film liquid in the gap of woven tube, Therefore film liquid does not combine firmly sufficiently with establishment pipe, and it is lower to be formed by hollow fiber film thread fastness.Two, the liner enhances Although the hollow fiber film thread of the hollow pricker dimension film spinnerette of type is longitudinally drawn constantly, the film liquid outside lateral woven tube is relatively held Easily automatically strip, it is easy to damage.Three, the production efficiency of the hollow fiber film thread of the hollow pricker dimension film spinnerette of the lining-reinforced It is lower.For another example Chinese invention patent application publication No. is CN104894663A, discloses a kind of New-type mould on September 9th, 2015 Block formula porous hollow fiber membrane spinning head, mainly by increasing spinneret hole number on a spinning head to be produced to improve Efficiency, but and do not solve the lower problem of hollow fiber film thread fastness produced.The utility model is by by high score casting film Liquid leads to the casting solution precoating device of front end installation, allows film liquid to penetrate sufficiently into establishment pipe seam gap with pressure, then weaving The outer layer of pipe coats macromolecule casting solution, and inside and outside two layers casting solution is sufficiently firmly combined with woven tube, so that being formed by hollow Fiber film wire has very high fastness；Furthermore spinnerette efficiency through the invention is imitated than the spinnerette of traditional technology Twice of rate raising or more.

Summary of the invention

Purpose of the utility model is to solve below the hollow pricker dimension film spinning head of lining-reinforced in the prior art 3 technical problems, one, hollow fiber film thread produced, film liquid with the sufficiently firm combination of establishment pipe, are not formed by Hollow fiber film thread fastness is lower, although because hollow fiber film thread produced is longitudinally drawn constantly, outside lateral woven tube Film liquid be easier to automatically strip, it is easy to damage.Two, film liquid coats unevenly outside woven tube, to influence the precision of filtering. Three, the lower technical problem of the production efficiency of the hollow fiber film thread of the hollow pricker dimension film spinnerette of the lining-reinforced, mentions Precoating device is added for one kind, is worked out in pipe seam gap by allowing film liquid to penetrate sufficiently into pressure, then coats height in outer layer Molecule casting solution, inside and outside two layers casting solution are sufficiently firmly combined with woven tube so that be formed by hollow-fibre membrane have it is very high Fastness, and the hollow pricker of lining-reinforced of high production efficiency ties up film spinning head.

The present invention solves the above problems used technical solution are as follows: a kind of hollow pricker dimension film spray of novel lining-reinforced Silk head, including first floor feeding plate, flow distribution plate, feeding plate and spinneret composition, it is the first floor feeding plate, the flow distribution plate, described Feeding plate and the spinneret be successively equipped with from top to bottom communicate with each other in be lining into hole, set on front side of the first floor feeding plate There is precoating casting solution entrance, which communicates with the casting solution precoating device being set in the flow distribution plate, described Casting solution precoating device is lining into hole with interior in the flow distribution plate and communicates；The front side of the feeding plate is equipped with casting solution entrance, should Casting solution entrance is communicated with the casting solution outer layer coating unit being set in the spinneret；The utility model can be by entering in the first floor The establishment inner tube layer that the casting solution precoating device being equipped in flitch and flow distribution plate is internally lining into hole carries out casting solution precoating, together Shi Liyong casting solution outer layer coating unit is internally lining into the establishment outer tube layer in hole and carries out casting solution coating；It is formed by hollow pricker Dimension film wire film liquid is sufficiently combined with woven tube ectonexine, and film liquid is not easily disconnected from woven tube and the intensity of film wire is high, furthermore film liquid It coats outside woven tube uniformly, so that the precision of filtering can be improved.
