Description

Technical Field

[0002] NMP is a colorless, transparent liquid with strong solubility and volatility. It is one of the important raw materials in the manufacturing process of lithium-ion batteries and directly affects the quality of lithium-ion battery slurry coating. NMP can also be used as a solvent for battery recycling and reuse. There are valuable materials in waste batteries, such as lithium and cobalt. The solubility of NMP can be used to dissolve the materials in waste batteries.

[0003] When the battery is decomposed by NMP solvent, the battery will be dissolved into a mixed solution composed of liquid and solid. Generally, the solid material and liquid in the battery are separated by centrifugal separation. During use, the centrifugal separation device separates and discharges the liquid in the mixed solution. Affected by the battery composition materials, the mixed solution produced after the battery is dissolved has a high viscosity, which makes it easy for the liquid to stick to the inner wall of the centrifugal separation device when it is separated and discharged. After a long period of accumulation, it is easy to cause the liquid in the device to flow and discharge poorly, affecting the movement of parts. It needs to be cleaned from time to time to ensure the normal operation of the device. However, in order to ensure the sealing and structural stability of the existing centrifugal separation device, the device is generally installed and fixed by bolts or welding, and cannot be disassembled, or the process is relatively complicated and labor-intensive, which is inconvenient for staff to operate.
