Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The novel integrated hollow tunica fibrosa spinneret of one as shown in Figure 1, comprise shower nozzle fixed head 1, sprayer body 2 and shower nozzle sleeve 3, the bottom of described shower nozzle sleeve 3 is provided with a cylindrical boss 31, described shower nozzle sleeve 3 center is provided with the uncovered circular cylindrical cavity in a upper end 32, the bottom of described circular cylindrical cavity 32 is provided with one and is communicated with and concentric feed liquid chamber 33 with it, the bottom in described feed liquid chamber 33 is provided with one through the spray silk forming hole 34 of cylindrical boss 31 bottom surface, the side of described shower nozzle sleeve 3 is uniform is provided with one or more feed liquid inlet 35 and described feed liquid inlet 35 is communicated to feed liquid chamber 33, the top of described sprayer body 2 is provided with together spindle head 24, described sprayer body 2 upper end center is provided with a core liquid hand-hole 21, described sprayer body 2 lower end is provided with a needle tubing 22, needle tubing hole 23 in described needle tubing 22 is connected with core liquid hand-hole 21, described sprayer body 2 socket joint is in circular cylindrical cavity 32 and needle tubing 22 is arranged in spray silk forming hole 34, the center of described shower nozzle fixed head 1 is provided with a centre bore 11, described centre bore 11 is sheathed on the concentric spindle nose 24 at sprayer body 2 top, described shower nozzle fixed head 2 and circular cylindrical cavity 32 inwall in shower nozzle sleeve 3 spin, and to compress sprayer body 2 downwards fixing.
Wherein, described sprayer body 2 and circular cylindrical cavity 32 inwall closely cooperate and needle tubing 22 with to spray silk forming hole 34 concentric; Bottom described sprayer body 2, needle tubing 22 joining place is provided with taper intermediate incline 25; Described feed liquid chamber 33 is provided with taper transition groove 36 with spray silk forming hole 34 joining place; Gap is there is in described sprayer body 2 with feed liquid chamber 33 inwall; The excircle of described shower nozzle fixed head 1 is provided with external screw thread, and described circular cylindrical cavity 32 upper inside wall is provided with internal thread; Described sprayer body 2 is greater than by hardness that the stainless steel of HRC40 is made to be formed.
The novel integrated hollow tunica fibrosa spinneret of one that above specific embodiment is mentioned, it is when concrete use assembling, as described below: the circular cylindrical cavity 32 first sprayer body 2 being loaded 3 li, shower nozzle sleeve, sprayer body 2 lower end needle tubing 22 is located in spray silk forming hole 34, and it is coaxial with spray silk forming hole 34, sprayer body 2 and circular cylindrical cavity 32 inwall closely cooperate, sprayer body 2 and circular cylindrical cavity 32 concentric can be ensured, again shower nozzle fixed head 1 is inserted on the concentric spindle nose 24 in sprayer body 2 upper end by centre bore, rely on shower nozzle fixed head 1 outside screw to screw in the internal thread of shower nozzle sleeve pipe 3 to tighten, sprayer body 2 and shower nozzle sleeve 3 are fixed together, shower nozzle fixed head 1 plays the effect of good stationary nozzle body 2.
In spinning process, feed liquid flows into spinning head from feed liquid inlet 35, sprays in pressure and flows by action of gravity pan feeding sap cavity 33 with the form of feed liquid stream from spray silk forming hole 34.On the other hand, core liquid flows into spinning head from core liquid inlet 21, flows in needle tubing hole 23, flows out from needle tubing hole 23 with the form of core liquid stream.
Because needle tubing hole 23 diameter is less than the diameter of spray silk forming hole 34, therefore core liquid stream by feed liquid stream around, make feed liquid stream form tubulose, thus form required hollow fiber film thread in operation afterwards.
According to the requirement of productivity ratio, suitable adjustment can be carried out to feed liquid and core liquid discharge pressure separately, hollow fiber film thread is stablized and sprays equably.
