Description

Technical Field

[0001] The utility model relates to the technical field of graphitization devices, and particularly relates to a continuous graphitization furnace for the production of graphite felt. Background Technique

[0002] Graphitization furnaces are mainly used for high-temperature treatments such as 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 materials, and other materials that can be graphitized in a carbon environment.

[0003] In order to solve the problems of the continuous graphitization furnace for graphite felt production, a continuous graphitization furnace for graphite felt production was published by a Chinese patent, with the publication number CN220039111U, including a furnace frame. The top surface of the furnace frame is provided with a graphitization furnace body. A plurality of hydraulic telescopic cylinders are fixedly installed on the inner bottom surface of the furnace frame. The reduction motor runs to make the gear drive the rack to rotate, so as to facilitate the forward extension of the conveying support plate, so that when the staff pulls out the support from the inside of the graphitization furnace body, it can be stored and supported, which is convenient for the staff to remove the support on the conveying support plate for subsequent operations. On the contrary, when it is necessary to put the support into the inside of the graphitization furnace body, just push the support onto the conveying support plate and make it rise, which is convenient for the staff to push the support into the inside of the graphitization furnace body. The device has a simple structure and convenient operation. Through the lifting of the U-shaped mounting seat, it is convenient for the conveying support plate to support the support, making the feeding and discharging more convenient;

[0004] However, the existing device still has the following problems: In this device, the graphite felt material is placed on the support plate and put into the graphitization furnace through the support plate to realize the production of graphite felt. However, during the process of taking out the support plate, since the graphite felt material is directly placed on the support plate, the graphite felt material is likely to fall off the support plate. Subsequently, it is necessary to manually take out the fallen graphite felt material, which affects the production efficiency of graphite felt. Therefore, a continuous graphitization furnace for graphite felt production is proposed. Content of the Utility Model
