Description

TECHNICAL FIELD

[0001] The utility model relates to a tunnel kiln technical field, especially in lithium battery production with energy -conserving and environment -friendly type tunnel kiln. BACKGROUND

[0002] The tunnel kiln for lithium battery production is a thermal equipment specially designed for lithium battery material production, which is mainly used for producing positive electrode materials of lithium ion batteries such as lithium iron phosphate (LFP) and ternary materials in the lithium battery industry. The tunnel kiln can control high and low temperature environment and oxygen flow, thereby ensuring that the positive electrode material is sintered into high-quality powder. In addition, the tunnel kiln is also used for drying negative electrode materials and heat treatment of battery modules. When the tunnel kiln is working, the positive electrode material enters the sintering section from the feeding port through the conveyor belt and is sintered at high temperature to form the required crystal structure. The sintered positive electrode material has high electrochemical performance and stability. The existing tunnel kiln often lacks heat preservation measures for the outer wall during use, and the outer wall cools down quickly, which leads to rapid heat loss and increases energy consumption, which is not conducive to energy saving and environmental protection. Therefore, we introduce a kind of energy -conserving and environment -friendly type tunnel kiln for lithium battery production. SUMMARY
