Description

Technical Field

[0001] The utility model relates to a relatively large range, in particular to a vertical graphitization furnace. Background Art

[0002] Graphitization furnace is mainly used for sintering and graphitization of carbon materials, graphitization of PI films, graphitization of thermal conductive materials, sintering of carbon fiber ropes, sintering and graphitization of carbon fiber filaments, purification of graphite powder and other high-temperature treatments of materials that can be graphitized under carbon environment. The operating temperature of graphitization furnace is as high as 3000℃, and it can handle various processes that need to be carried out under high temperature environment. The high temperature environment of graphitization furnace can convert amorphous substances in materials into crystalline substances, further reduce the number of grain boundaries of materials, thereby improving the performance of materials. Graphitization furnace can improve the conductivity of materials, reduce the resistance of materials, thereby improving the capacity and cycle performance of materials. The existing vertical When the graphitization furnace heats the raw materials into the graphitization furnace body, a feeding bin is generally installed on the top of the graphitization furnace. The inside of the graphitization furnace body is formed with an umbrella-shaped electromagnetic field for heating the raw materials through the negative electrode ring and the positive electrode pump. However, when the raw materials are added to the inside of the graphitization furnace body through the feeding bin, it is not convenient to make the raw materials present a circular structure, so that the four sides of the inside of the graphitization furnace body evenly fall into the inside of the graphitization furnace body, so as to evenly feed the negative electrode ring, which is not convenient to improve the practicability of the equipment and improve the uniformity of heating. In the process of feeding, it is easy to cause material accumulation on one side of the negative electrode ring, and less material in other directions, which is not convenient for uniform heating.
