Description

Technical Field

[0001] The invention relates to the technical field of product liquid removal and drying, and in particular to a carbon fiber precursor pre-oxidation exothermic cooling device. Background Art

[0002] In the preparation process of carbon fiber, pre-oxidation is a key step, which determines whether the precursor can be further converted into carbon fiber. During the pre-oxidation process, the precursor undergoes chemical reactions in a high temperature environment. These reactions will release a large amount of heat. If exothermic cooling is not performed in time, excessively high temperatures may cause changes in the structure of the precursor, resulting in thermal melting between the carbon fiber filaments, and in severe cases, the precursor may be scrapped. Therefore, an exothermic cooling device is required to exothermically cool the precursor. Existing exothermic cooling devices usually use water cooling to cool the precursor, and in order to avoid residual moisture affecting the quality of subsequent processing, the precursor will be dried.

[0003] Existing exothermic cooling devices usually use air knives to remove residual moisture from the precursor yarns wound on the roller body after water cooling, so as to achieve the purpose of drying the precursor yarns. As a common drying equipment, the working principle of the air knife is to blow the surface of the object through high-speed airflow to achieve the purpose of removing moisture or solvent. However, when this high-speed airflow is used to dry the carbon fiber precursor yarn, the cooling water moisture remaining on the surface of the precursor yarn will be blown away, resulting in most of the cooling water being difficult to recover. The cooling circulation water tank needs to be frequently replenished with water. Therefore, based on the above problems, a carbon fiber precursor pre-oxidation exothermic cooling device is proposed.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by setting structures such as the fan, the central through-hole and the drying and liquid collecting module, a group of dividing rollers aligned up and down can, on the one hand, divide and position each fiber thread to avoid the fiber threads being offset and overlapped due to the influence of the airflow, and on the other hand, can guide the fiber threads in the vertical direction, so that part of the moisture on the surface of the fiber threads can fall with gravity and fall into the cooling water bin, while the remaining moisture on the fiber threads can be processed by the drying and liquid collecting module. The operation is as follows: after the fan is started, the airflow is transported to the diversion pipe of the liquid removal part through the air supply pipe of the detection module and the central through-hole. When the airflow passes through the central through-hole, it is affected by the heating of the heating plate and becomes a hot airflow. The hot airflow is diverted through the diversion pipe and will be in the cone shell and on the lower side of the guide plate. Then, the hot airflow is discharged through the exhaust port through the downward guidance of the guide plate, so that the residual moisture on the surface of the fiber threads passing through the exhaust port is blown downward by the hot airflow. At the same time, the hot airflow will The surface of the fiber yarn is dried to complete the drying process of the fiber yarn, and most of the water blown off will be blocked by the baffle and fall on the roller surface of the transfer roller or in the liquid tank, and the displacement of the fiber yarn will drive the transfer rollers on both sides to rotate in the opposite direction, and then drive the liquid tank to rotate and displace in the direction of the liquid guide plate, so that the water in the liquid tank is poured onto the liquid guide plate, and falls into the liquid collecting shell of the infusion part through the guidance of the liquid guide plate, and then the collected water can be returned to the cooling water tank through the drain pipe, so that the heat release cooling device can dry the carbon fiber precursor and recycle the cooling water at the same time after the carbon fiber precursor is water-cooled, which solves the problem that the existing heat release cooling device usually uses an air knife to dry the carbon fiber precursor after the carbon fiber precursor is water-cooled, but the high-speed airflow of the air knife will blow away the cooling water and moisture remaining on the surface of the precursor, resulting in most of The cooling water is difficult to recycle, and it is necessary to frequently replenish the cooling circulation water tank, resulting in a waste of water resources; 2. In the present invention, by setting structures such as the moisture absorption roller, the detection module, the fan and the alarm, the fiber threads after the drying treatment will contact the moisture absorption sleeve of the moisture absorption roller when walking and moving, and drive the rotation of the moisture absorption roller. If the drying effect of the previous process is not good, moisture will remain on the surface of the fiber threads, which will be absorbed by the moisture absorption sleeve of the moisture absorption roller. When the airflow passes through the central passage, it will drive the transmission impeller of the transmission part to rotate, and the rotation of the transmission impeller will drive the driving shaft and the main gear to rotate. Since the main gear and the slave gear are meshed, the rotation of the main gear will drive the slave 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, so that the moisture absorption sleeve The moisture inside is squeezed out and falls into the base shell, and then flows into the measuring tube of the liquid measuring part through the base shell, and is detected by the liquid level sensor.

The exothermic cooling device can detect the drying treatment of the carbon fiber precursor after the carbon fiber precursor is dried, which solves the problem that the exothermic cooling device needs to dry the carbon fiber precursor after water cooling to avoid residual moisture from affecting the quality of subsequent processing. However, due to the excessive number of carbon fiber precursors processed at one time, it is difficult for the staff to control the drying condition of each carbon fiber precursor.

When the airflow passes through the middle through part 55, it is affected by the heating of the heating plate 553 and becomes a hot airflow, and the hot airflow is diverted through the diversion pipe 414 and will be in The hot air flows downward through the conical shell 411 and the lower side of the guide plate 412, and then the hot air flows downward through the guide plate 412 to be discharged through the exhaust port 413, so that the residual moisture on the surface of the fiber thread 3 passing through the exhaust port 413 is blown down by the hot air flow, and at the same time, the hot air flow dries the surface of the fiber thread 3 passing through the exhaust port 413, completing the drying process of the fiber thread 3, and most of the moisture blown off is blocked by the shield 421 and falls on the surface of the roller body 432 of the transfer roller 43 or in the liquid tank 434, while the fiber thread 3 The displacement of the silk thread 3 will drive the transfer rollers 43 on both sides to rotate in opposite directions, and then drive the liquid tank 434 to rotate and displace in the direction of the liquid guide plate 422, so that the water in the liquid tank 434 is poured onto the liquid guide plate 422, and falls into the liquid collecting shell 441 of the infusion part 44 through the guidance of the liquid guide plate 422, and then the collected water can be returned to the cooling water tank 23 through the drain pipe 443, so that the heat release cooling device can dry the carbon fiber precursor and recycle the cooling water at the same time after cooling the carbon fiber precursor with water;The operation of detecting the drying effect of the fiber thread 3 after the drying treatment is as follows. First, the fiber thread 3 after the drying treatment will contact the moisture absorption sleeve of the moisture absorption roller 16 when walking and moving, and drive the moisture absorption roller 16 to rotate. If the drying effect of the previous process is not good, then there will be residual moisture on the surface of the fiber thread 3, which will be absorbed by the moisture absorption sleeve of the moisture absorption roller 16. When the airflow passes through the central through portion 55, it will drive the transmission impeller 535 of the transmission portion 53 to rotate, and the rotation of the transmission impeller 535 will drive the driving shaft 532 and the main gear 534 to rotate. Since the main gear 534 and the slave gear 533 are meshed, the rotation of the main gear 534 will drive the slave gear 533 and the shaft 531 to rotate, and then drive the special-shaped wheel column 54 to rotate, so that the special-shaped The wheel column 54 can squeeze the moisture absorption sleeve of the moisture absorption roller 16, so that the moisture in the moisture absorption sleeve is squeezed out and falls into the base shell 51, and then flows into the measuring tube 571 of the liquid measuring part 57 through the base shell 51, and is 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 alarm, reminding the staff that the drying effect of the previous process is not good or there is a problem, 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, so that the heat release cooling device can detect the drying treatment of the carbon fiber precursor after the carbon fiber precursor is dried, so that the staff can timely control the drying condition of the carbon fiber precursor. ;
