Abstract
The utility model relates to an adjustable tunica fibrosa spinneret, which belongs to the technical field of the membrane separation technique. The utility model is characterized in that a spinneret seat is sheathed with a jet tube seat, a jet tube and the jet tube seat form a riveted connection, and the jet tube and the jet tube seat can adopt the approved products. The utility model has the advantages that the exchange, the adjustment and the maintenance are convenient, and the interchangeability is favorable; compared with the primary integrated spinneret, the service life is increased more than 11 times. Because the cover of the spinneret is designed with a material containing chamber, the stability of the spinning is increased, and the quality of the hollow tunica fibrosa is increased.
Description
The utility model relates to the spinning head apparatus of spinning hollow-fibre membrane in the membrane separation technique field, is characterized in providing a kind of hollow-fibre membrane spinning head of debugging that improves the doughnut film quality, enhances productivity.
Hollow-fibre membrane is a kind of important new material that the membrane technology field is applied to aspects such as ultrafiltration, counter-infiltration.Obtain more and more widely application gradually in many industries such as health care, food, environmental protection, chemical industry, electronics, demand is also increasing, therefore is subjected to domestic and international experts' great attention.For example, adopt the medical measure of artificial kidney hemodialysis at present to the patient of serious forfeiture renal function.And the critical material of manufacture of intraocular kidney haemodialyser and hemoconcentrator is exactly a hollow-fibre membrane.And spinning has certain requirement to the shaping of fiber and the dialysis performance of tunica fibrosa during hollow-fibre membrane, and this has just proposed strict requirement to the critical piece spinning head that spins hollow-fibre membrane.The most of employing of the separatory doughnut of spinning film inserted tubular type single hole spinning head both at home and abroad at present.All the novel solvent method cellulose hollow fiber film of the cellulose acetate hollow-fibre membrane of company's spinning and China Textile University, the development of Shanghai Red Star medical apparatus plant and polyacrylonitrile hollow-fibre membrane all adopt and insert the tubular type spinning head as the counter-infiltration hollow-fibre membrane of du pont company spinning B-9 dialyzer, broad-mouthed receptacle for holding liquid mountain.Endoporus was shaped easily when this spinning head advantage was the spinning doughnut, and can measure internal diameter wall thickness and the degree of hollowness that regulate doughnut by the filling liquid (or gas) of inserting the pipe input by control and regulation, when inside and outside pore good concentricity, the cross sectional shape of fiber is desirable, but its processing and manufacturing complexity, assembly difficulty is big, the outer hole of pipe is concentric in being difficult to guarantee, makes the doughnut difficult quality guarantee, and row yielding is also low, spinning head is scrapped manyly in the use, uses extremely inconvenient.
The patent No. of application Shanghai City, China Red Star medicine equipment material factory in October, 1988 be 88217582.3 monoblock type spinning head patent as shown in Figure 1.1 is showerhead base, and filling liquid enters from a, and 2 is body before the shower nozzle, and slurry injects from its side b, and 3 is jet pipe, and jet pipe 3 directly is riveted on the showerhead base 1.It is simply many that the structure of this spinning head is inserted tubular type, and the machining accuracy of the preceding body of shower nozzle etc. can be guaranteed from technology, and the spray orifice before the shower nozzle on the body and the concentricity of jet pipe are guaranteed that by mechanical structure mounting or dismounting are convenient, processing technology is reasonable.But this structure on showerhead base 1, is riveted very difficult by the direct riveting of thinner jet pipe.Although body spray orifice and jet pipe concentricity consider that from structural design it is very difficult to adjust both centers before the shower nozzle.Particularly,, waste very big in case jet pipe stops up or fractures then whole shower nozzle just scrapped because jet pipe directly is riveted on the showerhead base.
The purpose of this utility model provides the adjustable hollow-fibre membrane spinning head that a kind of interchangeability is good, install and remove convenience, economical with materials, raising doughnut film quality.
Technical characterstic of the present utility model is the spinning head apparatus of spinning hollow-fibre membrane in a kind of membrane separation technique, it comprises shower nozzle back seat, sprayer body, jet pipe and nozzle cap, it is characterized in that: suit the nozzle block that jet pipe is housed on the shower nozzle back seat, and the nozzle cap that is connected with sprayer body is provided with material-holding chamber.Another characteristics are that jet pipe is to be riveted on the nozzle block, and jet pipe and nozzle block can be selected equipped good off-the-shelf for use according to the requirement of required hollow-fibre membrane.Characteristics of the present utility model are that also close sprayer body one end of nozzle cap is provided with the material-holding chamber of a circle, and its diameter is 5-8mm, is 2-5mm deeply.
The utility model is owing to adopt the nozzle block of having riveted jet pipe to be sleeved on the shower nozzle back seat, in case only need to have assembled in the transposing immediately the nozzle block of jet pipe when generation slurry plugs or jet pipe fracture, or change the off-the-shelf in required aperture, can come into operation immediately, mounting or dismounting, transposing and adjustment are all very convenient, interchangeability is good again, has saved material, greatly reduces cost.Owing to only change jet pipe and seat thereof, the shower nozzle back seat service efficiency of spinning head is improved greatly, improve 10 times or more than monoblock type spinning head the service life of a spinning head of the utility model.Because easy accessibility can be used instead in process of production fast, has improved production efficiency and quality and can guarantee fully, this has just saved the many problems in the spinnerette.Design material-holding chamber on the nozzle cap and can store some slurries, played the effect of the pressure and the flow of stable slurry, can improve the quality of stability of spinning process and hollow-fibre membrane like this.
Accompanying drawing of the present utility model has:
Fig. 1 is a monoblock type hollow-fibre membrane spinning head structure chart;
Fig. 2 is adjustable hollow-fibre membrane spinning head structure chart.
Embodiment of the present utility model 2 is done following detailed description in conjunction with the accompanying drawings:
1 is the shower nozzle back seat in the accompanying drawing 2, and filling liquid enters from its center a.Jet pipe 4 is riveted on the nozzle block 3, and nozzle block is sleeved on the core pipe of shower nozzle back seat.Sprayer body 2 is equipped with the shower nozzle back seat, and connects with screw, and slurry injects from the side b of sprayer body 2.Nozzle cap 5 is contained on the sprayer body, and connects with screw.
This adjustable spinning head can be made series of products for selecting for use with jet pipe and nozzle block according to the requirement of different industries to the hollow-fibre membrane different size.
