Description
Technical Field
The utility model belongs to the technical field of precious metal smelting preparation, and particularly relates to a centrifugal cleaning device for silver powder production.
Background
In the noble metal silver smelting preparation process, after the silver powder is reduced in a reaction kettle, residual reducing liquid, metal silver ions, impurity ions, free nitric acid and dispersing agents are attached to the silver powder; therefore, silver powder can enter the next working procedure after being washed; it is very difficult to clean the nano-scale silver powder or the submicron-scale silver powder. Because superfine powder is easy to agglomerate, impurity ions existing in the system are easy to wrap. Therefore, during the silver powder cleaning process, the silver powder needs to be dispersed as much as possible, and the solid-liquid separation needs to be realized as much as possible. Therefore, we design the device. And solid-liquid separation is realized through centrifugation, and then the agglomerated silver powder is dispersed through high-speed dispersion. However, impurities cannot be completely cleaned by one-time washing, and the silver powder after centrifugation is generally wrapped by aggregation, and most of washing liquid residues are contained in the formed aggregation, wherein the impurities are contained in the aggregation; therefore, it is necessary to wash again after the dispersion is performed again at a high speed, and then to centrifuge until the content of impurities in the silver powder is extremely low.
Currently, the silver powder is mainly washed by siphoning. There is a problem in that the cleaning is not clean. In addition, the steps of washing, filtering and dispersing are required to be completed on different equipment in the current silver powder production process; repeating these steps a number of times means that the operator needs to constantly transfer the material in these several devices; for mass production, this will certainly increase production cost and labor cost, and in the course of multiple continuous transfer, material residues are unavoidable, and accumulation will cause significant loss of material.
