Core liquid needle plate is a plate, is furnished with several pin holes that run through top and bottom on plate, is interspersed with the core liquid pin of hollow in each pin hole, and core liquid pin stretches out in outside the bottom of core liquid needle plate; In the centre position of core liquid needle plate, inside has a feed liquid feeding-passage that connects both sides; Feed liquid feeding-passage is provided with a top feed liquid charging aperture that leads to lower outer;
Blanking tank is the buckle closure shape of opening up cavity, has several spinneret orifices in the bottom of blanking tank, and the core liquid pin on described core liquid needle plate is relatively inserted in spinneret orifice one by one; In blanking tank top position, both sides respectively have a side feed liquid charging aperture that connects respectively both sides sidewall.
On the two side of upper core flow container, respectively have an axisymmetric pin-and-hole, pin-and-hole connects from the top to the bottom; On the both sides of core liquid needle plate, also have the pin-and-hole of up/down perforation, communicate with the pin-and-hole on described upper core flow container; On the two side of blanking tank, have equally the pin-and-hole of up/down perforation, communicate with the pin-and-hole on described upper core flow container, core liquid needle plate; Upper core flow container, core liquid needle plate and blanking tank are determined upper-lower position by pin-and-hole, then are fixed together by screw.
Top feed liquid charging aperture in core liquid needle plate is located at the central area of feed liquid feeding-passage.
The utility model is removed the runner of the common core liquid in spinnerets and feed liquid, directly makes large cavity into, forms core liquid and feed liquid deposit in spinnerets, ensures that the discharging of each core liquid and feed liquid is stable and consistent.The utility model is simple in structure, with low cost, efficient low-consume.

Detailed description of the invention
Referring to Fig. 1, the utility model one plate multifibres hollow fibre spinneret, comprises upper, middle and lower-ranking, and upper strata is upper core flow container 1, and middle level is core liquid needle plate 2, and lower floor is blanking tank 3; Described upper core flow container 1, core liquid needle plate 2 and blanking tank 3 link into an integrated entity.
The structure of upper core flow container 1 is shown in Fig. 2 and Fig. 3, is the buckle closure shape of cavity.Be provided with core liquid charging aperture 1.1 in crown center position; On two side, respectively have an axisymmetric pin-and-hole 4, pin-and-hole 4 connects from the top to the bottom.
The structure of core liquid needle plate 2 is referring to Fig. 4 and Fig. 5, and core liquid needle plate 2 is a plate, is furnished with several pin holes that run through top and bottom on plate, is interspersed with the core liquid pin 2.1 of hollow in each pin hole, and core liquid pin 2.1 stretches out in outside the bottom of core liquid needle plate 2.In the centre position of core liquid needle plate 2, inside has a feed liquid feeding-passage 2.2 that connects both sides; The central area (being the central area of core liquid needle plate 2) of feed liquid feeding-passage 2.2, is provided with a top feed liquid charging aperture 2.3 that leads to lower outer.On the both sides of core liquid needle plate 2, also have the pin-and-hole 4 of up/down perforation, communicate with the pin-and-hole 4 on described upper core flow container 1.
The structure of blanking tank 3 is shown in Fig. 6 and Fig. 7, is the buckle closure shape of opening up cavity.Have several spinneret orifices 3.1 in the bottom of blanking tank 3, the core liquid pin 2.1 on described core liquid needle plate 2 is relatively inserted in spinneret orifice 3.1 one by one.In blanking tank 3 top positions, both sides respectively have a side feed liquid charging aperture 3.2 that connects respectively both sides sidewall.On the two side of blanking tank 3, have equally the pin-and-hole 4 of up/down perforation, communicate with the pin-and-hole 4 on described upper core flow container 1, core liquid needle plate 2.
