AI Technical Summary
Technical Problem
The graphite particles are squeezed centrally on the inner wall of the stirring drum due to centrifugation, resulting in insufficient contact with the asphalt solution, resulting in uneven coating.
Method used
A liquid phase coating device for lithium battery material powder is designed, and the liquid in the mixing kettle is extracted and sprayed back to the inside, so that the graphite particles can move rapidly with the solution to the middle of the mixing kettle, reducing aggregation and mutual extrusion contact, ensuring uniform contact with the bitumen solution.
Benefits of technology
Through this device, the contact between the graphite particles and the asphalt solution becomes sufficient and uniform, the coating effect is improved, and the stirring time is shortened.

Abstract
The present invention discloses a liquid-phase coating device for lithium battery material powder and a liquid-phase coating method, and specifically relates to the field of graphite coating. The liquid-phase coating device for lithium battery material powder includes a mounting frame, an end cap and a mixing kettle are arranged on the mounting frame, a turntable is arranged at the bottom of the inner side of the mixing kettle, a rotary drive component is arranged at the bottom of the outer side of the mixing kettle, the output end of the rotary drive component is fixedly connected to the middle of the turntable, and the rotary drive component is used to drive the turntable to rotate so as to stir the mixed solution in the mixing kettle; an internal particle spraying assembly is arranged on the mounting frame, and the internal particle spraying assembly includes a water pump. In the process of stirring the mixed liquid, the natural graphite particles move rapidly to the middle of the mixing kettle along with the solution sprayed from the liquid inlet nozzle, thereby reducing the aggregation of the natural graphite particles and the degree of mutual extrusion contact, and also making the solution in the middle of the mixing kettle be utilized, the natural graphite particles are in full contact with the asphalt solution, the coating is uniform, and the stirring time is shortened.
