Abstract
The utility model relates to a hollow cored fiber film spinneret. The center of the top end of a jet head body is provided with an upper groove loosely provided with a jet body. The center of the jet body is provided with an inner cylindrical hole communicated with a transition taper hole. The outer edge of the jet body is provided with staircase-shaped lower and upper outer edges. A plurality of adjusting screws positioned on a horizontal plane with intervals is arranged on the jet body in radial direction, and the top ends of the adjusting screws contact the lower outer edge of the jet body. Accordingly, the concentricity of the inner and outer pores can be increased, and the utility model can be suitable for the spin manufacture of hollow cored fiber film with different dimension, decreasing cost of equipment.
Description
The utility model relates to a kind of spinning head of hollow-fibre membrane.
As everyone knows, hollow-fibre membrane is widely used in industries such as health care, food, environmental protection, chemical industry and electronics, and spinning during hollow-fibre membrane shaping and the fiber permeability of the membrane to fiber certain requirement is arranged, especially the inside and outside pore concentricity to spinning head has strict requirement; At present, common insertion tubular type spinning head, its endoporus are shaped easily, still, have only by accurate processing and assembling to guarantee, the concentricity of inside and outside pore for the concentricity requirement of this endoporus with outer hole, often is difficult to reach; In the last few years, also the someone attempted to increase a jet pipe cover for seat between jet pipe and nozzle boss, jet pipe is riveted on nozzle block puts, and was coupled to then in the nozzle boss, and its inside and outside pore concentricity still depends on the accuracy of machinery assembling.
In view of this, the purpose of this utility model provides a kind of adjustable hollow-fibre membrane spinning nozzle mould, can reach the concentricity of inside and outside pore to adjust outer pore center, and part replacement is easy in addition simultaneously.
The purpose of this utility model is achieved in that a kind of adjustable hollow-fibre membrane spinning nozzle mould comprises sprayer body, and gland and nozzle tube is characterized in that: center, sprayer body top has upper groove; One spout body is set in this upper groove loosely, and the center of this spout body has interior cylindrical hole and the transition taper hole that is connected, and its outer rim has stepped outer rim and last outer rim down; Nozzle tube is to be made of base and the jet pipe one that protrudes upward, sprayer body radially be provided with on the horizontal plane separately several adjustment screw and the top of this adjustment screw contact with outer rim under the spout body.
Shoulder under the above-mentioned spout body between outer rim and the last outer rim contacts with the gland lower surface.
Owing to adopt such scheme: can improve the concentricity of inside and outside pore, also adapt to the spinning of the hollow-fibre membrane of different size, reduce equipment cost greatly.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 the utility model exemplary embodiments structural representation.
Among the figure: 1 sprayer body, 11 advances slurry hole, 12 upper grooves, 13 interstitial holes, 14 times centre bores, 15 radially cylindrical holes, 24 transition taper holes, 3 adjustment screw, 4 glands, 5 nozzle tubes, 51 jet pipes, 52 bases, 53 feed liquors (gas) through hole in the outer rim, 23 on screw, 2 spout bodies, the 21 times outer rims, 22.
Present embodiment comprises sprayer body 1, spout body 2, several adjustment screw 3, gland 4 and nozzle tube 5, as shown in Figure 1, and wherein:
Sprayer body 1 has into, and slurry hole 11, upper groove 12, interstitial hole 13 reach radially screw 15 of centre bore 14 and several, wherein upper groove 12 is the cylinder grooves at center, sprayer body 1 top, be communicated with interstitial hole 13, following centre bore 14 (less than interstitial hole 13) in regular turn downwards, entering slurry hole 11 is the horizontal holes that are communicated with interstitial hole 13 (material-holding chamber) lower end outer rim from sprayer body 1 outer rim, in addition, the radially screw 15 of several five equilibriums is horizontally set on sprayer body its outer rim of 1 connection and upper groove 12.
Spout body 2 is that the center has interior cylindrical hole 23 and the transition taper hole 24 that is connected, and outer rim has the ladder cylinder of following outer rim 21 and last outer rim 22, this spout body 2 places on upper groove 12 bottom surfaces of sprayer body 1 with its bottom surface, and have the slit between outer rim 21 and upper groove 12 walls under it, its transition taper hole 24 is communicated with the interstitial hole 13 of sprayer body 1 again.
Adjustment screw 3 is screwed in the radially screw 15 of sprayer body 1, and its top contacts with the following outer rim 21 of spout body 2, and mobile spout body 2 makes its center line and sprayer body 1 central lines, the concentricity of promptly regulating both.
Gland 4 is the lids with centre bore, on the shoulder with 22 of its lower surface contact 2 times outer rims 21 of spout body and last outer rims, be connected with screw on the end face of sprayer body 1, and keep 22 of the last outer rims of its centre bore and spout body 2 to have the slit, for the position of regulating spout body 2.
Nozzle tube 5 is to protrude upward long jet pipe 51 (stepped) at base 52 centers, and the center also has a feed liquor (gas) through hole 53, this nozzle tube 5 connects (connecting with screw) on sprayer body 1 bottom with its base 52, and cooperate with the following centre bore 14 of sprayer body 1 with its jet pipe 51 outer rim of getting out of a predicament or an embarrassing situation, to keep interstitial hole 13 centers of jet pipe 51 at sprayer body 1, in addition, feed liquor (gas) through hole 53 is the through holes that enter filling liquid (gas).
