Description

Technical Field

[0001] This utility model relates to the field of graphitization furnace technology, and in particular to a high-purity graphite high-temperature heat treatment furnace for heat recovery and utilization. Background Technology

[0002] High-purity graphite high-temperature heat treatment furnaces are widely used in semiconductor, photovoltaic, lithium battery anode materials, nuclear industry and other fields for high-temperature processes such as graphitization, carbonization and purification. For example, a Chinese patent discloses an ultra-high temperature graphitization heat treatment furnace, application number: 202122266979.5. Although the heating furnace components can automatically open the lid to avoid dust affecting personnel health, and the automatic door components can facilitate loading and unloading of materials, saving manpower and improving efficiency, the materials still need to be discharged manually or mechanically after heat treatment, which can easily lead to damage to the graphite materials. Moreover, the opening operation will cause the high-temperature gas in the furnace to dissipate rapidly, which not only increases the energy consumption of subsequent heating, but also reduces the working temperature of the waste heat recovery system and reduces the overall heat recovery rate.
