AI Technical Summary
Traditional solid-liquid separation equipment suffers from low separation efficiency and unstable operation when processing high-concentration, easily agglomerated lithium carbonate slurry. Furthermore, the material discharge stage is prone to blockage, affecting the continuous operation of the equipment.
Design a solid-liquid separation device for lithium carbonate precipitation process. The device uses crushing rollers to crush large particles and combines dynamic vibration and automatic cleaning structure of filter frame to achieve efficient crushing, dynamic filtration and automatic cleaning, thereby improving separation efficiency and equipment stability.
It significantly improves the stability and efficiency of solid-liquid separation, avoids filter pore clogging, and enhances the automation level and continuous operation capability of the equipment.
