Description

Technical Field

[0002] In the lithium carbonate processing and preparation process, in order to improve the subsequent drying efficiency of lithium carbonate, it is usually necessary to dehydrate the lithium carbonate solution through a centrifugal device to facilitate the processing and preparation of lithium carbonate. Common centrifugal devices are usually used intermittently. After the lithium carbonate solution is placed in the centrifugal device, the solution needs to be centrifuged first, and then the concentrated lithium carbonate solution after centrifugation is taken out, and then new lithium carbonate solution is injected for centrifugal dehydration. This method causes the centrifugal device to work discontinuously, and common centrifugal devices usually only have one filtration. The water flow generated after centrifugation often contains lithium carbonate, which can easily cause material waste. A recovery device needs to be set up to recycle the water flow generated by centrifugation, which increases the process cost and is not conducive to the production and preparation of lithium carbonate.
