Description

Technical Field

[0001] The utility model belongs to the technical field of carbonization wires, and particularly relates to a supporting component of a graphite heater of a carbonization furnace of a carbonization wire. Background Art

[0002] As a lightweight composite material with excellent mechanical properties, high and low temperature resistance, corrosion resistance and fatigue resistance, carbon fiber is currently widely used in aerospace, national defense, transportation, energy, sports and leisure and other fields. The industry is currently highly competitive, and cost reduction and efficiency improvement have become new development trends.

[0003] From the perspective of the carbon fiber production process, the carbonization treatment in the carbonization furnace stage requires high temperature and high energy consumption, so the cost is relatively high. Therefore, technology upgrades and process optimization have become the inevitable means to solve the high production cost. By increasing the width of the carbonization furnace of the carbonization line, the annual output of the single line can be increased to reduce unit energy consumption and other costs. At present, the width span of the carbonization furnace production line is between 0.5-3m, and the width of the carbonization furnace needs to be further increased to more than 4m. Because the heating component of the carbonization line is a graphite heater, and the heating tube that makes up the graphite heater is limited by the material, the maximum length can only be 3m. To form a production width greater than 4m, the graphite heater needs to be made into a spliced ​​structure. Because the span of the spliced ​​graphite heater after splicing is large, the middle part sags greatly, which may cause the middle of the spliced ​​graphite heater to deform and break in severe cases. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a support assembly for a graphite heater of a carbonization furnace of a carbonization line.
