System and method for reducing moisture content and impurity content of nickel cobalt hydroxide

A system for reducing the moisture content and impurity content of nickel cobalt hydroxide, which comprises a thickener, a cleaning equipment, a pressure filtration equipment, and a transit silo that are arranged sequentially along the direction of slurry conveyance;

• wherein, the cleaning equipment comprises a shell, a mixing device, a water source device, and a steam pipe;
• the shell is provided with a cleaning tank and is also provided with a material inlet, a steam inlet, and a material outlet that are connected to the cleaning tank;
• the material inlet of the shell is connected to the material outlet of the thickener, while the material outlet of the shell is connected to the pressure filtration equipment;
• the mixing device, located within the shell, is used to agitate and wash the material inside the cleaning tank;
• the water source device is utilized to inject water into the cleaning tank;
• the steam pipe is wrapped around the periphery of the transit silo, with its outlet connected to the steam inlet;
• the steam pipe serves to convey secondary steam generated in the high-pressure smelting area into the cleaning tank after heat exchange with the material inside the transit silo.
