Cathode material precursor reaction concentration integrated device

By designing a cylindrical filter element and a double-layer agitator structure inside the ternary precursor reactor, the problems of long process, high cost and low reaction efficiency caused by the separation of the ternary precursor reactor and the thickener are solved. This achieves efficient circulation of slurry and stable flow inside the reactor, thereby improving production efficiency.

AI Technical Summary

Technical Problem

The existing separation of ternary precursor reactors and concentrators results in a long process, high cost, and complex operation. Furthermore, the filtration equipment installed in the reactor affects the fluid flow direction and reduces reaction efficiency.

Method used

A cathode material precursor reaction and concentration integrated device is designed. By optimizing the structure of the filtration device, multiple filter elements are arranged in a cylindrical shape along the circumference. Combined with a double-layer agitator, the first agitator provides axial thrust to the inclined blades, and the second agitator provides radial thrust and shear force to the straight blades, forming a spiral flow field to promote slurry circulation.

Benefits of technology

It improves the fluidity of the slurry in the reactor and the reaction efficiency, reduces process steps, lowers operational complexity, and ensures the reliability and production efficiency of the filtration equipment.
