Abstract
The utility model discloses a kind of solidification liquid concentration control apparatus, comprising: online refractometer, digitial controller, pneumatic operated valve, concentration sensor; Pneumatic operated valve is located on moisturizing passage, one end of moisturizing expanding channels solidification liquid case, and the other end of solidification liquid case connects solidification liquid passage, stores solidification liquid in solidification liquid case; Concentration sensor is located on solidification liquid passage, online refractometer connecting sensor and digitial controller, and pneumatic operated valve connects digitial controller.Adopt the technical solution of the utility model, can continous-stable reed time controll solidification liquid concentration.
Description
Technical field
The utility model relates to fibre technology field, particularly relates to a kind of solidification liquid concentration control apparatus.
Background technology
Heteroaromatic polyamide fiber (aramid III) be with paraphenylenediamine, to dibenzoyl chlorine, 5 (6)-amino-2-(p-aminophenyl) benzimidazoles for raw material, through batching, copolycondensation, telomerize, forced filtration, deaeration obtain heavy polymer solution (spinning slurry), then form through wet method counter-current spinning, washing, drying, high-temperature heat treatment.
Spinning process: spin slurry from spinneret cap ejection, soak through solidification liquid, washing spray, dry, rolling, then pass on heat treatment step.
From the tow of spinneret cap ejection, containing a large amount of DMAC (dimethylacetylamide) solvent, salinity and impurity, in suitability for industrialized production, soaked by solidification liquid and removed.Solidification liquid is formed by DMAC, salinity and water proportioning, and both concentration are different, acts on also difference to some extent.The slurry sprayed by spinneret cap is frozen into silk by solidification liquid, and permeates tow precipitation most of solvent, salt wherein; Whole process of setting is the process of a balance, if solidification liquid excessive concentration, infiltration are too slow, the precipitation of the impurity such as solvent salt is insufficient, has a strong impact on tow intensity; If concentration is too low, infiltration is too fast, and tow inside easily produces bubble, can reduce tow intensity equally, even tow fracture.So the control solidi fication liquid concentration of continous-stable is most important.And in prior art, control to be by field sampling to the concentration of solidification liquid, gas chromatographic analysis sample obtains concentration value, and operating personnel are again according to this value, and manually opened moisturizing regulates the concentration of solidification liquid, and rate of water make-up is entirely by rule of thumb.The method operation is complicated, and the concentration of solidification liquid constantly changes, at all can not continous-stable reed time controll solidification liquid concentration, has a strong impact on the strength and stability of tow.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of solidification liquid concentration control apparatus, can continous-stable reed time controll solidification liquid concentration.
For solving the problem, the utility model adopts following technical scheme:
A kind of solidification liquid concentration control apparatus, be installed on the solidification liquid passage in aramid III spinning process, for controlling the solidification liquid concentration in solidification liquid case, solidification liquid expanding channels, in solidification liquid case, comprising: moisturizing passage, online refractometer, digitial controller, pneumatic operated valve and concentration sensor;
Moisturizing expanding channels is in solidification liquid case, and moisturizing passage is provided with pneumatic operated valve; Concentration sensor is located on solidification liquid passage, and online refractometer connects concentration sensor and digitial controller, and pneumatic operated valve connects digitial controller.
A kind of solidification liquid concentration control apparatus, pneumatic operated valve is the pneumatic operated valve of band locator.
Solidification liquid concentration control apparatus of the present utility model adopts digitial controller to obtain the solidification liquid concentration of solidification liquid passage according to concentration sensor, controls pneumatic operated valve and water is injected solidification liquid case, realize automatically controlling the concentration of solidification liquid.The utility model make solidification liquid concentration can control preferably concentration set point ± 5% within, and control continuously, stable, adjustable, whole-process automatic control, (staff only need set concentration target value on digitial controller) easy and simple to handle in good time, quality and the stability of tow improve a lot, and lousiness, fracture of wire phenomenon significantly reduce.
Accompanying drawing explanation
Fig. 1 is solidification liquid concentration control apparatus structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, utility model provides a kind of solidification liquid concentration control apparatus, be installed on the solidification liquid passage in aramid III shredding process in tow heat treatment process, for controlling the solidification liquid concentration in solidification liquid case, solidification liquid expanding channels, in solidification liquid case, comprising: moisturizing passage, online refractometer 2, digitial controller 3, pneumatic operated valve 4, concentration sensor 1.
Pneumatic operated valve 4 is the pneumatic operated valve of band locator; Moisturizing passage is provided with pneumatic operated valve 4; Moisturizing expanding channels is in solidification liquid case; Solidification liquid is stored in solidification liquid case.
Concentration sensor 1 is located on solidification liquid passage, and online refractometer 2 connects concentration sensor 1 and digitial controller 3, and pneumatic operated valve 4 connects digitial controller 3.
Solidification liquid concentration signal on solidification liquid passage is sent to online refractometer 2 by concentration sensor 1, concentration signal converting analogue signals is sent to digitial controller 3 by online refractometer 2, digitial controller to analog signal after PID arithmetic process, export the control signal of 4 ~ 20mA to pneumatic operated valve 4, regulate its aperture, water is injected solidification liquid case, realize automatically controlling the concentration of solidification liquid.
The detailed description of the invention of just this utility model described in description.Although describe embodiment of the present utility model by reference to the accompanying drawings, in this area, those skilled in the art can make various distortion or amendment within the scope of the appended claims.
