AI Technical Summary
In the traditional modular segmented cooling kiln frame structure used in lithium battery roller kilns, the material takes too long to cool down after sintering in the kiln, which cannot meet the requirements for efficient cooling. In particular, the cooling efficiency for silicon-carbon anode materials is insufficient, causing silicon particles to undergo irreversible expansion due to prolonged high temperature, which affects battery performance.
The modular segmented cooling kiln frame structure includes an operating platform, rollers, first and second cooling chambers, a cooling mechanism, and a fixing mechanism. Air is compressed by an air compressor and cooled by spraying it through nozzles. The nozzle angle is adjusted by an electric push rod, and heat exchange is carried out using heat exchange tubes. The heat exchange tubes are quickly connected and sealed by a locking block and a sealing ring.
The cooling rate of the material was increased, ensuring that the material reached the target temperature in a short time, avoiding silicon particle expansion caused by high temperature, and improving battery performance.
