Abstract
Description
Technical Field
[0001] This application relates to the field of spinning technology, and more specifically, to a coagulation bath apparatus for chemical fiber spinning. Background Technology
[0002] High-end knitwear made from acrylic filament boasts numerous advantages: a silk-like feel and luster, lightweight, excellent breathability and wrinkle resistance, strong colorfastness, even dyeing, good settling, and good retention. After further processing and weaving, the yarn exhibits a pear-skin texture, giving it a refreshing and elegant sheen and color. Its excellent colorfastness and abrasion resistance add a more vibrant touch to knitwear. High-end woven garments made from acrylic filament are brightly colored, have a strong wool-like texture, excellent drape, and subtle reflective points, resulting in a luxurious appearance unmatched by other synthetic fibers.
[0003] In the production process of acrylic filament, the dosing solution is sprayed out using a spinneret to form a fine stream. The dosing solution stream solidifies into nascent fibers in a coagulation bath. However, traditional coagulation baths are just simple tanks. During use, it is difficult to keep the temperature inside the tank and the concentration of the liquid inside the coagulation bath consistent. This affects the quality of the nascent fibers solidified from the dosing solution stream in the coagulation bath, which in turn affects the subsequent processing of finished products, impacting product quality. Long-term use can also introduce impurities. Utility Model Content

[0031] Please see Figures 1-6 This application provides a coagulation bath device for chemical fiber spinning, including a coagulation bath assembly 100 and a circulation assembly 200.
[0032] Please see Figure 1 , 2 3. The coagulation bath assembly 100 includes a groove 110, a rotating roller 120, a traction wheel 130, and a temperature control component 150. The rotating roller 120 is rotatably disposed in the groove 110, the traction wheel 130 is disposed on the inner wall of the groove 110, and the temperature control component 150 is disposed in the groove 110.
[0033] The constant temperature component 150 includes a first thermoelectric cooler 151 and a second thermoelectric cooler 152. The first thermoelectric cooler 151 is fixedly embedded on the outside of the groove 110, and the second thermoelectric cooler 152 is fixedly embedded on the inside of the groove 110. By setting the first thermoelectric cooler 151 and the second thermoelectric cooler 152, the cooling surface of the first thermoelectric cooler 151 is located inside the groove 110, and the heating surface of the second thermoelectric cooler 152 is located inside the groove 110. Heating or cooling is achieved by switching the two thermoelectric coolers on and off.
[0034] Specifically, a thermometer 160 is fixedly installed through the groove 110. The thermometer 160 is close to the first semiconductor cooling chip 151. By setting the thermometer 160, the temperature of the solution in the coagulation bath is monitored in real time to keep it in a suitable temperature range for coagulation into acrylic filaments.
[0035] In one specific implementation, a drain pipe 170 and a valve are connected to one side of the U-shaped trough 110. The drain pipe 170 and the valve are used to drain the liquid after use for replacement.
[0036] In this embodiment, a support column 111 is fixedly connected to the groove 110, and an extension plate is provided at the bottom of the support column 111. By setting the support column 111 and the anti-slip extension plate, the overall positioning stability is improved.
[0037] Please see Figure 1 , 24, 5 and 6, the circulation assembly 200 includes a liquid pump 210, a fixing plate 220, a fixing cylinder 230, a filter element 240 and a cover plate 250. The liquid pump 210 is installed in the loop groove 110, the fixing plate 220 is fixedly connected to the loop groove 110, the fixing cylinder 230 is fixedly inserted through the fixing plate 220, the filter element 240 is disposed in the fixing cylinder 230, and the cover plate 250 is disposed on the top of the fixing cylinder 230.
[0038] The fixed cylinder 230 has an opening 231 at the top, and the cover plate 250 is adapted to the opening 231. The opening 231 is used for the filter element 240 to be put in and replaced, and then the cover plate 250 is installed to seal it.
[0039] In this embodiment, the end of the cover plate 250 is provided with an extension block 251 and a fixing bolt is threaded through it. The fixing cylinder 230 is provided with a positioning groove 232. The extension block 251 is inserted into the positioning groove 232. By setting the extension block 251 to be inserted into the positioning groove 232 of the fixing cylinder 230, and then using the fixing bolt to pass through the extension block 251 and connect it to the threaded hole of the fixing cylinder 230, the cover plate 250 is installed and fixed.
[0040] In one specific implementation, the fixed cylinder 230 is located near the liquid inlet end of the liquid pump 210, and the liquid pump 210 is located between the thermostat 150 and the fixed cylinder 230.
[0041] The working principle of this coagulation bath device for chemical fiber spinning is as follows: During operation, the liquid pump 210 is started, which draws the solution in the loop trough 110. The solution passes through the fixed cylinder 230 and enters the filter element 240. After being filtered by the filter element 240, the solution enters the liquid pump 210 again and flows out from the outlet end of the liquid pump 210 back into the loop trough 110 and towards the rotating roller 120. The flowing solution passes through the rotating roller 120, which not only filters out most of the impurities, preventing impurities from affecting the coagulation quality of the product, but also mixes the solution, enabling it to circulate. The solution concentration is uniform, and the flowing solvent solution ensures that the acrylic filaments coming from the spinneret receive a consistent concentration, thus guaranteeing product quality consistency. At the same time, the cooling surface of the first semiconductor cooling chip 151 is located inside the groove 110, which can cool the solution. The heating surface of the second semiconductor cooling chip 152 is located inside the groove 110, which can heat the solution. The temperature is detected by thermometer 160 to ensure that the solvent solution temperature is within a suitable range, further ensuring that the acrylic filament reaction temperature is appropriate and guaranteeing product quality.
[0042] It should be noted that the specific model and specifications of the liquid pump 210 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0043] The power supply and operating principle of the liquid pump 210 are clear to those skilled in the art and will not be described in detail here.
[0044] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
