Description

Technical Field

[0001] The utility model relates to the technical field of a graphitization cooling device for graphite negative electrode materials, in particular to a graphitization cooling device for graphite negative electrode materials. Background Art

[0002] The graphitization process is a process that makes full use of resistance heat to heat the carbonaceous material to 2300-3000℃, so that the amorphous chaotic layer structure of carbon is transformed into an ordered graphite crystalline structure. The energy for the transformation of graphite crystalline structure and atomic rearrangement comes from high-temperature heat treatment. As the heat treatment temperature increases, the distance between graphite layers gradually decreases, generally between 0.343 and 0.346nm. Generally, the temperature changes significantly when it reaches 2500℃, and changes gradually slowly when it reaches 3000℃ until the entire graphitization process is completed. Artificial graphite negative electrode materials are successfully transformed from carbon structure to graphite structure through high-temperature graphitization treatment, and have the corresponding functions of lithium battery negative electrode. During the graphitization cooling process, the negative electrode material cannot be forced to cool by pouring water, which will have a comprehensive negative impact on the quality of the main material and auxiliary materials. Generally, natural cooling is adopted.

[0003] The existing graphite negative electrode material graphitization cooling has the problem that the heat of the negative electrode material covered in the lower layer is not easy to dissipate, resulting in a low overall cooling speed and uneven cooling. In order to overcome these disadvantages, the utility model provides a graphite negative electrode material graphitization cooling device. Utility Model Content
