[0002] In the prior art, after graphitization is completed, it is necessary to cool the insulating material inside the graphitization furnace. Currently, the more common temperature reduction methods include natural cooling and artificial cooling methods. Natural cooling is to open the furnace cover and let the high-temperature insulating material inside the furnace cool to room temperature in a natural cooling manner. Although this method is simple and easy to implement, it has the disadvantages of long cooling time, low production efficiency, incomplete internal cooling, and easy impact on product quality. The artificial cooling method is to sprinkle water from the top of the furnace manually. Although this method can shorten the cooling time, it has the disadvantages of high labor intensity of workers and poor working conditions. The generated high-temperature steam contains harmful substances and is easy to scald workers. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is that when cooling a large-scale graphitization furnace, the natural cooling method has a long cooling cycle, is not convenient for production, the artificial sprinkling method is labor-consuming, and has a certain degree of danger.
