[0002] The carbon atoms of carbonaceous materials are arranged irregularly. Only through high-temperature heat treatment at 2200℃~2600℃ can the carbon atoms be recrystallized and rearranged in order to present the crystal structure of graphite, thus having many excellent properties of graphite, such as significantly improved electrical and thermal conductivity, better chemical and thermal stability, reduced impurities, lower hardness, easier machining, etc. The function of the graphitization furnace is to convert carbonaceous materials into artificial graphite materials, such as providing high-quality carbon element graphite materials for steel smelting, aluminum smelting, negative electrode materials, other non-ferrous metal industries, nuclear industry, etc.

[0003] The existing CN105967180B patent document proposes a graphitization furnace, in which a control device is arranged on the top of the furnace body. The control device controls the feeding speed by controlling the opening size of the feeding pipe at the connection with the heating furnace, so that the graphitization furnace can work continuously while ensuring that the graphitization furnace has extremely high graphitization efficiency.

[0004] However, the graphitization furnace will generate a large amount of dust during the processing. Due to the lack of a device to collect the dust, the dust will spread into the air, polluting the environment and affecting the health of the workers. Moreover, the dust can be recycled, and the inability to collect the dust will increase the production cost. Summary of the invention
