Description

Technical Field

[0001] The utility model belongs to the technical field and relates to a sagger material pre-crushing device. Background Art

[0002] Lithium-ion battery cathode materials are generally prepared by high-temperature solid-phase method. The preparation process is to mix the precursor and lithium salt in a certain proportion, put the mixed materials into the sagger, and then send them into the kiln for high-temperature sintering. The sintering temperature is generally 750℃-1050℃. After sintering, the powder is crushed, sieved, and iron removed to obtain the lithium battery cathode material powder. However, the powder material after high-temperature sintering will form a solid block with high hardness and will adhere to the surface of the sagger, making it difficult to pour the sagger out of the sagger after sintering. The material in the sagger after sintering needs to be pre-crushed.

[0003] At present, one of the pre-crushing solutions is to fix the crushing tool on the automatic conveying line of the kiln sagger. When the sagger is conveyed to the bottom of the crushing tool, the cylinder drives the lifting device to lift the sagger upward, and the crushing tool splits the material in the sagger. However, the cylinder-driven lifting device cannot control the lifting speed of the sagger, and can only rise to a fixed position in one step without a buffering process, which leads to a high extrusion intensity on the sagger, and the sagger is easy to crack and break, resulting in an increase in the breakage rate of the sagger; at the same time, it is impossible to control the strength of the crushing tool to split the material, and the crushing effect is not good for materials with higher hardness. Therefore, it is urgent to solve the above problems. Utility Model Content
