Description

technical field [0001] The invention relates to the field of cobaltous hydroxide preparation equipment, in particular to a pressure filter device for purifying cobaltous hydroxide. Background technique [0002] Cobaltous hydroxide is a positive electrode material. The cobaltous hydroxide solution is prepared by a filter press device, but the traditional press filter equipment is a commonly used squeeze filter press with a low reciprocating rate. There are a lot of impurities mixed in the liquid, and the precision is low. In summary, a pressure filter device for purifying cobaltous hydroxide is urgently needed to solve the above-mentioned problems. Contents of the invention [0003] The purpose of the present invention is to provide a filter press device for purifying cobaltous hydroxide, to solve the problem that the traditional press filter equipment proposed in the above-mentioned background technology is a commonly used squeeze filter press, the reciprocating speed is l...
