Description

Technical Field

[0001] The utility model relates to the technical field of countercurrent washing, in particular to a countercurrent washing device for cobalt leaching residue. Background Art

[0002] Countercurrent washing is the process of washing the filter cake in a countercurrent manner after filtration with a solvent (called a washing liquid). This process aims to recover valuable residual filtrate or further remove soluble impurities from the filter cake to improve the purity of the solid product. Countercurrent washing is typically performed in a multi-stage (e.g., three-stage) continuous countercurrent washing system. Countercurrent washing allows for relatively satisfactory washing results with a smaller amount of washing liquid. It is commonly used when washing cobalt leaching residues.

[0003] When the existing cobalt leaching residue countercurrent washing device is in use, most of the filter cakes are fixed inside the device, and the filter cakes are a flat structure, which makes it inconvenient to recover the filter residue in the filter cake. At the same time, most of the existing washing devices are integrated structures, which makes it inconvenient to clean the inside of the device. Utility Model Content
