Description
Technical field
The present invention relates to dry-jet wet-spinning stabilization technology field, particularly relate to a kind of dry-jet wet-spinning spinnerets apparatus for adjusting position.
Background technology
Dry-jet wet-spinning is the main technique that para-aramid fiber is prepared in processing.The key step of dry-jet wet-spinning be spinning solution after spinning nozzle ejection, first through a bit of air layer (usual thickness is only 2-25 millimeter), then enter in non-solvent coagulating bath the solid fabric of the orientation that is separated, is solidified into.Although the length of air section is only several millimeter, the macromolecular orientation in solution mainly occurs in this region.The mechanical property of polymer depends on the orientation of interior molecules significantly, and the degree of orientation is higher, and Mechanical Properties of Materials are better.Therefore polymer determines the performance of final prepared fiber at the drafting process of air section.In addition, in dry jet wet-spinning procedure, partial solvent, in air section gasification volatilization, defines very thin compacted zone on solution thread surface.This layer of compacted zone, the double diffusion speed that can slow down between fiber solution thread and coagulating bath, stop in as-spun fibre and form large hole, make to solidify the fibre bundle obtained finer and close, surface is more smooth.
But because the distance of spinnerets and coagulating bath liquid level is very short, be only several millimeter, horizontality difference trickle on filament spinning component, the liquid stream that diverse location spinning nozzle all can be caused to flow out all can experience the air section of different length before contact coagulating bath.At present, the installation of filament spinning component and Level tune carry out mainly through the range estimation of installer, and simply estimate and cannot tell the trickle inclination of filament spinning component.If the installation due to filament spinning component there occurs the trickle inclination that naked eyes cannot be differentiated, one end air layer length is caused to be 3mm, and other end air layer length is 5mm, then the air layer difference in length of diverse location can reach 40%, this species diversity will have a strong impact on the structural behaviour of fiber in a synnema, considerably increase the discreteness of fibre bundle, and the discreteness of fibre property on different station.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of dry-jet wet-spinning spinnerets apparatus for adjusting position, can adjust to parallel with coagulating bath liquid level by the spinneret plane of filament spinning component, the Distance geometry time that the dynamic analysis of spinning that each spinning nozzle is sprayed stops in air layer is equal.
The technical solution adopted for the present invention to solve the technical problems is to provide a kind of dry-jet wet-spinning spinnerets apparatus for adjusting position, comprise filament spinning component and coagulation bath cell wall, described filament spinning component external stability arranges positioning jacket, described positioning jacket shape and filament spinning component match, height is identical with filament spinning component, three pieces of height adjustment bolt are set above described positioning jacket, positioning jacket is connected with the bracing frame of top by height adjustment bolt, conducting probe is provided with immediately below described positioning jacket is corresponding with three pieces of height adjustment bolt, the length that three conducting probes stretch out positioning jacket is consistent, and and between the filament spinning component of process requirements and coagulation bath cell wall the distance of air layer match, between conducting probe and coagulation bath cell wall, measure loop is set, energization indicating device is provided with in described measure loop.
Described filament spinning component is cylinder.
Described positioning jacket is annulus.
Described three pieces of height adjustment bolt are evenly distributed on positioning jacket.
Described height adjustment bolt and positioning jacket are threaded connection.
Described filament spinning component is fixedly connected with by bolt or pin with between positioning jacket.
The installing hole inserted for conducting probe is provided with below described positioning jacket.
Described conducting probe is connected to the positive pole of measure loop, and coagulation bath cell wall is connected to the negative pole of measure loop.
Described energization indicating device is electric current admittance indicator lamp or warning device.
Beneficial effect
The present invention is on the basis not changing original spinning component structure, at its outer setting positioning jacket, be provided with three pieces of bolts that can carry out highly regulating above positioning jacket, filament spinning component can move up and down along with the lifting of positioning jacket, thus the horizontality of adjustment filament spinning component.Three conducting probes arranged below positioning jacket, the length of stretching out positioning jacket is consistent, and and the distance of air layer matches between the filament spinning component of process requirements and coagulation bath cell wall, rotation height adjusting bolt, when the moment that conducting probe contacts with coagulating bath liquid level, the energization indicating device in measure loop sends power on signal.When three measure loop are energized just, the spinnerets of filament spinning component is adjusted to parallel with coagulating bath liquid level.Present arrangement avoids the accurate not drawback of perusal leveling, not only increase the guarantee of the spinnerets horizontality to filament spinning component, also make the distance controlling of spinnerets and coagulating bath liquid level more accurate, the uniformity of spinning bundle is increased substantially, discreteness reduces, and the tow stuctures and properties also making different station produce is more consistent.
