Description

Technical Field

[0001] This utility model relates to a cooling device, specifically a graphitization furnace head cooling device, belonging to the field of auxiliary cooling technology for graphitization furnaces. Background Technology

[0002] Graphitization furnaces are widely used in industrial production for the high-temperature treatment of carbon materials. Their core components include the furnace body, furnace head, and cooling system. These components work together to achieve efficient and uniform heating and cooling processes. The furnace head, as a critical feeding and discharging component, needs to maintain good sealing performance and mechanical stability under high-temperature conditions. However, the furnace head itself does not have a cooling function, and natural cooling would be inefficient.

[0003] Chinese Patent Publication CN212720902U discloses a graphitization furnace head cooling device. The device involves fitting a collar onto the outlet flange of the furnace head, tightening the clamping element onto the furnace head with bolts, and then cooling the furnace head and the material discharge by circulating hot and cold gas through the cooling pipe. The device is easy to install and disassemble.

[0004] In practical applications, it was found that the cooling pipe, return gas pipe, and furnace head stone of the aforementioned patent are interconnected. Therefore, the return gas pipe may restrict the effective return flow of air, resulting in incomplete mixing of cooling gas and hot gas, leading to poor return flow. Therefore, a furnace head cooling device for graphitization furnaces is proposed here. Utility Model Content
