At the microstructure of nascent hollow-fibre membrane.Solvent and additive in casting solution containing higher concentration, at one section of continuous production
Between after, the solvent strength near as-spun fibre film wire starts slowly to improve, and double diffusion rate consecutive variations show as same batch
Film wire performance slightly has gap.There is company using the method recycled in slot to solve the problems, such as this, but circulation is easy in water-bath in slot
Surface forms lateral current, impacts nascent hollow-fibre membrane, is easy that film wire is made defect occur.How do not influence as-spun fibre into
In the case where entering coagulating bath, solves the problems, such as that as-spun fibre film stablizes exchange in production process, become those skilled in the art's urgency
Problem to be solved.
Utility model content
Purpose of utility model：The technical problem to be solved by the utility model is to provide a kind of hollow-fibre membranes in Wet-spinning
Process units during silk, the device can guarantee the steady production of hollow-fibre membrane, improve the production matter of hollow-fibre membrane
Amount.
In order to solve the above technical problems, technical solution used by the utility model is：
A kind of process units of hollow-fibre membrane during wet spinning, including spinning head, convolution diversion pipe and solidification
Bath, the spinning head are fixedly connected with convolution diversion pipe by connector；The convolution diversion pipe and spinning head are in vertical side
Upward coaxial setting；The coagulating tank is built-in with working solution, and the convolution diversion pipe is located at the liquid of working solution in coagulating tank
Below face；The convolution diversion pipe is in C font, and the convolution diversion pipe includes that outlet and entrance, the entrance pass through diaphragm pump
It is connected with thermostatic bath, the outlet is connected by ball valve with thermostatic bath；It is equidistantly equipped on the inside of the convolution diversion pipe multiple
Aperture.
Further, multiple godet rollers are additionally provided in the coagulating tank.
Further, the buckle for connecting with connector is also symmetrically arranged on the convolution diversion pipe.
Further, the outer diameter of the convolution diversion pipe is 2~5 times of spinning head outer diameter.
Further, the opening direction of convolution diversion pipe inside aperture is directed to the center of convolution diversion pipe；Aperture
Aperture along convolution water conservancy diversion tube inlet successively successively decrease to export direction.
Further, the convolution diversion pipe multiple can be also coaxially disposed along longitudinal direction, and the entrance of multiple convolution diversion pipes is simultaneously
The outlet of connection connection diaphragm pump, multiple convolution diversion pipes is connected in parallel ball valve,
Compared with prior art, technical solutions of the utility model have the advantage that for：
Utility model device can guarantee that the solvent (working solution i.e. in coagulating tank) near as-spun fibre film wire is real
It now recycles, is gradually risen so as to avoid the solvent solubility generated due to continuous production and ultimately cause same batch film wire performance
Difference；Meanwhile compared to the method recycled in slot, utility model device is avoided that the solvent table in slot in circulation time slot again
Face forms lateral current, impacts nascent hollow-fibre membrane, causes the defect of film wire；The apparatus structure simple realization is convenient, significantly
Improve the cost performance of Film Growth.

Fig. 2 is the convolution diversion pipe top view in the utility model process units；
Fig. 3 is the structural schematic diagram of the utility model process units.
Specific embodiment
The technical solution of the utility model is described further below in conjunction with attached drawing, but the requires of the utility model is protected
Range be not limited thereto.
As shown in Figure 1-3, process units of the utility model hollow-fibre membrane during wet spinning, including spinning head
8, circle round diversion pipe 3 and coagulating tank 6, and spinning head 8 is fixedly connected with convolution diversion pipe 3 by connector 9；Circle round diversion pipe 3
With spinning head 8 in setting coaxial on vertical direction；Coagulating tank 6 is built-in with working solution 10, and convolution diversion pipe 3 is located at coagulating tank
In 6 below the liquid level of working solution 10；Circle round diversion pipe 3 be in C font, convolution diversion pipe 3 include outlet and entrance, entrance by every
Membrane pump 2 and thermostatic bath 1 connect, and outlet is connected by ball valve 4 and thermostatic bath 1；3 inside of diversion pipe circle round equidistantly equipped with multiple
Aperture 31；The diversion pipe 3 that circles round can also be in polygon.
Convolution diversion pipe 3 multiple can be also coaxially disposed along longitudinal direction, and the entrance of multiple convolution diversion pipes 3 is connected in parallel diaphragm pump
2, the outlet of multiple convolution diversion pipes 3 is connected in parallel ball valve 4.
The opening direction of convolution 3 inside aperture 31 of diversion pipe is directed to the center of convolution diversion pipe 3；The aperture edge of aperture 31
Convolution 3 entrance of diversion pipe successively successively decreases to export direction.The card for fixedly connected part 9 is also symmetrically arranged on convolution diversion pipe 3
Button 32；The outer diameter of convolution diversion pipe 3 is 2~5 times of 8 outer diameter of spinning head.
Working fluid is equipped in thermostatic bath 1, the working fluid in thermostatic bath 1 is pumped into convolution diversion pipe 3 by diaphragm pump 2
Entrance, the working fluid a part being pumped into is recycled into constant temperature by final after ball valve 4 from the outlet export of convolution diversion pipe 3 again
Bath 1；Another part liquid sprays during through convolution diversion pipe 3 from aperture 31, and the working fluid directive of ejection returns
Revolve the center that diversion pipe 3 surrounds structure.Convolution 3 internal pressure size of diversion pipe can be realized by adjusting ball valve 4, to realize small
Hole 31 sprays the adjustable of working liquid pressure.Since the pressure of convolution 3 entrance of diversion pipe to outlet is different, by the way that aperture 31 is arranged
Size is successively successively decreased along entrance to export direction, realizes that different apertures spray the consistency of fluid pressure.
When utility model device works, connector 9 one are fixed on spinning head 8, and other end will be returned by bayonet 32
It is fixed to revolve diversion pipe 3, keeps convolution diversion pipe 3 coaxial in vertical direction with spinning head 8, guarantees that the tunica fibrosa 7 that spinning head 8 sprays is rigid
The good center across convolution diversion pipe 3.Meanwhile the diversion pipe 3 that circles round is placed in the lower 1~3cm of 10 liquid level 10 of working solution in coagulating tank 6
Place.
When tunica fibrosa 7 passes through convolution 3 center of diversion pipe, the working solution that aperture 31 sprays just is applied on tunica fibrosa 7, is produced
Raw corresponding effect, realizes the normal production of tunica fibrosa 7.Since the working fluid that aperture 31 sprays is working fluid, avoid
Working fluid works long hours the density unevenness of generation；Meanwhile multiple apertures 31 generate liquid miniflow, reduce to tunica fibrosa
Impact, avoid the defect of film wire.
Tunica fibrosa 7, again by extracting out from coagulating tank 6 after several godet rollers 5, carries out behind convolution 3 center of diversion pipe
Next stage process.
