Abstract
The utility model relates to a hollow fiber membrane single-end spinneret plate, which comprises a base, a core body disposed on the base and an upper cover which penetrates through the core body to be matched with the base in fixedly fitting mode. A core liquid pipe in hollow structure is arranged inside the core body. A T-shaped core rod, a conical core head and a spinning nozzle are in integral structure. One end face of a base is provided with a groove, and the other end face of the base is provided with a round groove. A pin hole communicated with a conical groove is disposed at the central position of the round groove. The ratio of the hole diameter of the spinning nozzle to the hole diameter of the pin hole is 2 to 1. At least one spinning solution passage communicated with the conical groove is evenly distributed on the outer side of the base in annular mode. By adopting combination of the base and the upper cover, the hollow fiber membrane single-end spinneret plate is capable of playing a sealing role effectively, enables the spinning solution passage to be communicated with the conical groove, is capable of avoiding leakage of the spinning solution during the spinning solution injection process, ensures uniformity of wall thickness of a hollow fiber membrane, and thus ensures quality of products and stability of production.
Description
Technical field
The utility model relates to the hollow-fibre membrane production field, especially a kind of hollow-fibre membrane single head spinnerets.
Background technology
Membrane separation technique has been compared separation accuracy with traditional isolation technics high, and energy consumption is low, and is easy to operate, and therefore plurality of advantages such as environmentally safe are applied to fields such as medicine, food, environmental protection and daily life more and more widely.Press the shape branch of film; At present the pattern of film has flat, rolling, tubular type and doughnut etc., and present existing fiber formula film is mainly milipore filter and micro-filtration membrane, and the former separation accuracy is high; Latter's separative efficiency is high; The aperture of supermicro filtration membrane is between milipore filter and micro-filtration membrane, and its separation accuracy is higher than micro-filtration membrane, and separative efficiency is higher than milipore filter again.
At present, in the hollow-fibre membrane of producing both at home and abroad, what adopt basically is the insertion tubular type spinning head of the logical liquid of center ventilation or center; The spinneret orifice of this kind spinning head, its guide hole are long thinner, and the bottom spinning nozzle is consistent with the doughnut diameter; In guide hole, insert breather pipe or fluid-through tube, doughnut forms between spinning nozzle inwall and central gas stream, and this spinning head requires central aeration pipe and spinning nozzle that accurate concentricity is arranged; The doughnut that has skew to produce slightly promptly is eccentric shape, causes wall unevenness even, causes spinnerets production efficiency lower easily; Cost is higher, and make, the difficulty of assembling spinnerets mould is also bigger.
The utility model content
The technical problem that the utility model will solve is: in order to overcome the above-mentioned middle problem that exists, a kind of manufacturing is provided, assembles hollow-fibre membrane single head spinnerets simple and the assurance product quality.
The utility model solves the technical scheme that its technical problem adopted: a kind of hollow-fibre membrane single head spinnerets; Comprise base and be arranged on the core body on the base and pass core body and the loam cake of base secure fit; The core liquid pipe that has hollow structure in the described core body; Core body by T core bar be arranged on the taper core print of T core bar front end and the spinning head that is fixed on the taper core print is formed, described T core bar, taper core print and spinning head are overall structure, offer groove on described base one end face; Groove is by forming with mutually close-fitting annular groove of T core bar quarter butt end and conical socket that can ccontaining taper core print; Between taper core print and the conical socket cavity is arranged, the just in time corresponding conical socket of the spinning head on taper core print bottom, the bore of described annular groove is greater than the bore of conical socket and form step-like; Offer circular groove on the other end; Described circular groove offers the pin hole that is connected with conical socket on the center, and described spinning head aperture is 2: 1 with the ratio of pinhole aperture, and annular is uniformly distributed with and offers the spinning solution passage that at least one is connected with conical socket on the described chassis outer side face.
Even for the tunica fibrosa wall thickness that can make generation, annular is evenly equipped with four spinning solution passages on the described chassis outer side face.
The beneficial effect of the utility model is: the hollow-fibre membrane single head spinnerets of the utility model, and the employing base combines with loam cake, can play sealing function effectively; The spinning solution passage is connected with conical socket; Can when injecting spinning solution, utilize the combination of core body can spinning solution be flowed out from pin hole; Avoid leaking outside of spinning solution, guaranteed that the wall thickness of hollow-fibre membrane is even, thereby guaranteed the quality of product and the stability of production.
