Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of material transportation, and specifically relates to a discharging device. BACKGROUND

[0002] Graphitization is a key step in the production process of lithium-ion battery negative materials, aiming to convert thermodynamically unstable carbon materials into ordered graphite crystal structure, thereby improving the electrochemical performance of the material. This process usually needs to be carried out in a graphitization kiln, and the material is heated to a high temperature of 2000℃ or above, so that the carbon atoms are rearranged and form a graphite structure. The material after completing graphitization needs to be cooled to near room temperature before discharging, in order to avoid damage to the subsequent processing equipment by high-temperature materials and to ensure the safety of the operators.

[0003] At present, the discharging methods of the graphitization compartment furnace mainly include manual discharging and mechanized discharging. The manual discharging method has low cost, but has low efficiency and safety hazards, especially for battery negative material production environment which strictly controls metal foreign matter, manual operation may cause foreign matter to be introduced, affecting product quality. The mechanized discharging scheme, such as the suction crane, although improves the discharging efficiency and reduces the risk of manual operation, but its equipment is complex, inconvenient to maintain, and when the material temperature is high (such as more than 80℃), the equipment will start the self-protection program, and high-temperature discharging cannot be realized, which limits the production efficiency and resource utilization.

[0004] Manual operation needs a long time to complete discharging, especially when the amount of material is large. And the operator needs to enter the high-temperature environment, increasing the risk of burns and other injuries.
