The function of conveying and processing the precursor to finally obtain the carbon fiber is realized, but the following problems exist:
1. Through utilizing conveying components such as bundle silk roller and silk roller to transport precursor and carbon fiber silk, can only carry out single transportation in proper order, it is slow, leads to production efficiency low, and during the transportation, need carry out tensioning to it, transport by frictional force, leads to the transportation unstable.
2. When pre-oxidation, carbonization and graphitization are carried out, only a single precursor enters the reaction chamber, so that waste of larger heat energy is caused, the precursor treatment effect is poor, the processing efficiency is low, and when the carbon fiber is subjected to surface treatment afterwards, the transportation efficiency is also low.
3. Because the carbon fiber wires are relatively slim and have small surface areas, when the surface treatment is performed, the spray nozzle is selected to spray the carbon fiber wires, so that the carbon fiber wires cannot be uniformly sprayed, and the surface treatment is uneven.
4. Since more harmful gases are generated when the pre-oxidation, carbonization and graphitization treatment are performed in the reaction chamber, the retention of internal heat is also required, and thus the sealability of the reaction chamber is required to be ensured.
5. When the reaction chamber needs to be ventilated, more heat is wasted in the exchanged waste gas, and the fresh air entering the reaction chamber needs to be reheated, so that the heating efficiency is reduced.
Therefore, it is necessary to provide a multifunctional processing apparatus for carbon fiber tows, which can achieve the effect of high-efficiency production.
