Description

Technical Field

[0001] The utility model relates to the technical field of extraction, in particular to a novel platinum, palladium and rhodium extraction device. Background Art

[0002] Extraction, also known as solvent extraction or liquid-liquid extraction, is a unit operation that uses the different solubilities of components in the system to separate the mixture. That is, it is a method of transferring the solute from one solvent to another solvent by using the difference in solubility or distribution coefficient of the substance in two immiscible (or slightly soluble) solvents.

[0003] Most of the existing platinum, palladium and rhodium extraction equipment are fixed structures, which are not convenient to move. During the extraction process, the raw materials and reactants are often allowed to react statically, and the reaction speed is slow, which leads to a slow extraction speed. Moreover, most of the extracted substances are poured out or clamped out, which not only wastes time but also may cause waste of materials. Therefore, the utility model proposes a novel platinum, palladium and rhodium extraction equipment to solve the above-mentioned problems. Utility Model Content
