Description

Technical Field

[0001] The present invention relates to the technical field of liquid removal and drying of products, and specifically to a pre-oxidation exothermic cooling device for carbon fiber precursor filaments. Background Art

[0002] In the preparation process of carbon fiber, pre-oxidation is a crucial step, which determines whether the precursor filament can be further transformed into carbon fiber. During the pre-oxidation process, chemical reactions occur in the precursor filament under a high-temperature environment, and these reactions will release a large amount of heat. If the exothermic cooling is not carried out in time, the excessive temperature may cause changes in the structure of the precursor filament, resulting in the thermal fusion between carbon fiber filaments, and seriously may lead to the scrapping of the precursor filament. Therefore, an exothermic cooling device is needed to perform exothermic cooling on the precursor filament. The existing exothermic cooling devices usually use water cooling to cool the precursor filament, and in order to avoid the quality impact of residual moisture on subsequent processing, the precursor filament will be dried.

[0003] The existing exothermic cooling devices usually use air knives to remove the residual moisture from the precursor filament wound around the roller body after water cooling, so as to achieve the purpose of drying the precursor filament. As a common drying device, the working principle of the air knife is to blow the surface of an object with a high-speed air flow to achieve the purpose of removing moisture or solvent. However, when this high-speed air flow dries the carbon fiber precursor filament, it will blow the residual cooling water moisture on the surface of the precursor filament everywhere, resulting in most of the cooling water being difficult to recover, and it is necessary to frequently replenish the cooling circulating water tank. Therefore, according to the above problems, a pre-oxidation exothermic cooling device for carbon fiber precursor filaments is proposed. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. In the present invention, through structures such as the blower, the middle through part, and the drying liquid collection module, a set of wire dividing rollers arranged vertically and aligned can, on the one hand, divide and position each fiber silk thread, avoiding the situation of the fiber silk thread shifting and overlapping under the influence of air flow. On the other hand, it can guide the fiber silk thread in the vertical direction, so that part of the moisture on the surface of the fiber silk thread can fall due to gravity and fall into the cooling water tank. The remaining moisture on the fiber silk thread can be processed by the drying liquid collection module. The operation is as follows: After the blower is started, air flow is conveyed to the shunt pipe of the liquid removal part through the air delivery pipe and the middle through part of the detection module. When the air flow passes through the middle through part, it becomes hot air flow under the influence of the heating plate. The hot air flow is shunted through the shunt pipe and is located below the conical shell and the deflector. Then, through the downward diversion of the deflector, the hot air flow is discharged through the air outlet, so that the residual moisture on the surface of the fiber silk thread passing through the air outlet is blown down by the hot air flow. At the same time, the hot air flow will dry the surface of the fiber silk thread passing through the air outlet, completing the drying process of the fiber silk thread. Most of the moisture blown down will be blocked by the shielding cover and fall on the roller surface of the transfer roller or into the liquid tank. The displacement of the fiber silk thread will drive the two transfer rollers to rotate away from each other, thereby driving the liquid tank to rotate and displace towards the liquid guide plate, so that the moisture in the liquid tank is poured onto the liquid guide plate and falls into the liquid collection shell of the liquid infusion part through the guidance of the liquid guide plate. Then, the collected moisture can be recycled back to the cooling water tank through the drain pipe. It realizes that after the heat release cooling device cools the carbon fiber precursor by water cooling, it can simultaneously dry the carbon fiber precursor and recycle the cooling water, solving the problem that after the existing heat release cooling device cools the carbon fiber precursor by water cooling, it usually uses an air knife to dry the carbon fiber precursor, but the high-speed air flow of the air knife will scatter the residual cooling water moisture on the surface of the precursor everywhere, resulting in most of the cooling water being difficult to recycle, and the cooling water circulation tank needs to be replenished frequently, resulting in a waste of water resources;

[0015] 2. In the present invention, through structures such as a moisture absorption roller, a detection module, a blower, and a warning device, the fiber silk thread after drying treatment will contact the moisture absorption sleeve of the moisture absorption roller during the walking displacement, driving the rotation of the moisture absorption roller. If the drying treatment effect in the previous process is not good, moisture will remain on the surface of the fiber silk thread, which will be absorbed by the moisture absorption sleeve of the moisture absorption roller. When the air flow passes through the middle through part, it will drive the transmission impeller of the transmission part to rotate. The rotation of the transmission impeller will drive the drive shaft and the main gear to rotate. Since the main gear and the driven gear are meshed, the rotation of the main gear will drive the driven gear and the shaft rod to rotate, and then drive the special-shaped wheel column to rotate, so that the special-shaped wheel column can squeeze the moisture absorption sleeve of the moisture absorption roller, and the moisture in the moisture absorption sleeve will be extruded and fall into the base shell, and then flow into the measuring tube of the liquid measuring part through the base shell. It is detected by the liquid level sensor. If the water level reaches the standard, the liquid level sensor will send an electrical signal to the controller, and the controller will control the warning device to alarm, reminding the staff that the drying treatment effect in the previous process is not good or there are problems. It realizes that the heat release cooling device can detect the drying treatment situation of the carbon fiber raw silk after the drying treatment of the carbon fiber raw silk, and solves the problem that the heat release cooling device needs to dry the carbon fiber raw silk after water cooling to avoid the quality impact of residual moisture on the subsequent processing. However, due to the large number of carbon fiber raw silk processed at one time, it is difficult for the staff to control the drying situation of each carbon fiber raw silk.

Through this setting, if the water level in the measurement tube 571 reaches the standard, the liquid level sensor 573 will send an electrical signal to the controller 17, and the controller 17 will control the alarm 18 to give an alarm.

[0039] Workflow: The cooling and drying treatment of carbon fiber by the carbon fiber precursor pre-oxidation exothermic cooling device is as follows. Notice 1: All electrical appliances in this solution are powered by an external power supply and are controlled by the controller 17 to operate. Notice 2: After the water pump 25 is started, the cooling water in the cooling water tank 23 can be transported to the heat exchanger 21 through the circulating outlet pipe 22 for temperature reduction treatment. The cooled cooling water then flows back to the cooling water tank 23 through the circulating return pipe 24 to complete the circulation of the cooling water and keep it at a relatively low temperature all the time. Notice 3: By removing the lower end of the drain pipe 443 from the hole position of the cooling water tank 23 and pulling out the hanging bracket 442 from the hanging hole 424, the infusion part 44 can be detached from a set of guide covers 42, enabling a set of guide covers 42 and the transfer roller 43 to rotate to both sides after losing the limit of the hanging bracket 442. Notice 4: The moisture in the measuring pipe 571 can be discharged by removing the sealing plug 572. Notice 5: When the fan 19 accidentally stops operating due to an error after the equipment in this solution runs, the controller 17 will also activate the alarm 18 to avoid the functional failure of the drying liquid collection module 4 and the detection module 5 caused by the shutdown of the fan 19.The first and last guiding roller sets 14 arranged on the left and right can serve as the inlet and outlet ends for guiding the transmission of the fiber filaments 3. The guide roller 15 can conduct the direction of the fiber filaments 3, enabling the fiber filaments 3 to enter the cooling water tank 23 of the cooling section 2 for water cooling and temperature reduction treatment. The set of wire dividing rollers 13 arranged vertically aligned can, on the one hand, divide and position each fiber filament 3 to prevent the fiber filaments 3 from shifting and overlapping under the influence of air flow. On the other hand, it can guide the fiber filaments 3 in the vertical direction, allowing some of the moisture on the surface of the fiber filaments 3 to fall due to gravity into the cooling water tank 23. The remaining moisture on the fiber filaments 3 can then be processed by the drying liquid collection module 4. The operation is as follows: After the fan 19 is started, it conveys air flow through the air delivery pipe 56 and the middle through section 55 of the detection module 5 to the shunt pipe 414 of the liquid removal section 41. The air flow becomes hot air under the heating effect of the heating plate 553 when passing through the middle through section 55. The hot air is shunted through the shunt pipe 414 and is located inside the conical shell 411 and below the flow guiding plate 412. Then, through the downward flow guiding of the flow guiding plate 412, the hot air is discharged through the air outlet 413, causing the residual moisture on the surface of the fiber filaments 3 passing through the air outlet 413 to be blown down by the hot air. At the same time, the hot air will dry the surface of the fiber filaments 3 passing through the air outlet 413, completing the drying treatment of the fiber filaments 3. Most of the blown-down moisture is blocked by the shielding cover 421 and falls on the roller body 432 surface of the transfer roller 43 or into the liquid tank 434. The displacement of the fiber filaments 3 will drive the two-sided transfer rollers 43 to rotate away from each other, thereby driving the liquid tank 434 to rotate and displace towards the liquid guiding plate 422, causing the moisture in the liquid tank 434 to pour onto the liquid guiding plate 422 and fall into the liquid collection shell 441 of the liquid infusion section 44 through the guiding of the liquid guiding plate 422. Then, through the drain pipe 443, the collected moisture can be recycled back into the cooling water tank 23, enabling the heat release cooling device to simultaneously dry the carbon fiber roving and recover the cooling water after water cooling and temperature reduction of the carbon fiber roving;The detection operation of the drying effect of the fiber silk thread 3 after drying is as follows. First, when the fiber silk thread 3 after drying moves, it will contact the moisture-absorbing sleeve of the moisture-absorbing roller 16 and drive the rotation of the moisture-absorbing roller 16. If the drying effect of the previous process is not good, then there will be moisture remaining on the surface of the fiber silk thread 3, which will be absorbed by the moisture-absorbing sleeve of the moisture-absorbing roller 16. When the air flow passes through the middle through part 55, it will drive the drive impeller 535 of the drive part 53 to rotate. The rotation of the drive impeller 535 will drive the drive shaft 532 and the main gear 534 to rotate. Since the main gear 534 and the driven gear 533 are meshed, the rotation of the main gear 534 will drive the driven gear 533 and the shaft rod 531 to rotate, and then drive the special-shaped wheel column 54 to rotate, so that the special-shaped wheel column 54 can squeeze the moisture-absorbing sleeve of the moisture-absorbing roller 16, and the moisture in the moisture-absorbing sleeve will be squeezed out and fall into the base shell 51, and then flow into the measuring tube 571 of the liquid measuring part 57 through the base shell 51 and be detected by the liquid level sensor 573. If the water level reaches the standard, the liquid level sensor 573 will send an electrical signal to the controller 17, and the controller 17 will control the alarm 18 to give an alarm, reminding the staff that the drying effect of the previous process is not good or there are problems, so that the staff can timely maintain the drying liquid collection module 4 or adjust the power of the fan 19 and the heating plate 553, enabling the heat release and cooling device to detect the drying situation of the carbon fiber raw silk after the drying treatment of the carbon fiber raw silk, so that the staff can timely control the drying situation of the carbon fiber raw silk.;
