Description

Silver powder transfer device

Technical Field

The utility model relates to a metallurgical technical field of noble metal, in particular to silver powder transfer device.

Background

Electrolytic refining of silver employs charging a silver nitrate electrolyte with a coarse silver anode and cathode. After current is introduced, the silver and base metal impurities at the anode are dissolved, pure silver is separated out at the cathode, and the cathode silver is separated out in a granular form, namely silver powder. Because the silver is precipitated in the form of granular crystals, the growth speed of the cathode silver is fast in the form of dendrite, and the cathode silver is easy to fall off in the electrolytic process. In order to prevent the cathode dendritic silver from generating short circuit, a scraper is used for scraping. The silver powder dropped from the cathode was directly sunk onto the conveyor belt at the bottom of the electrolytic cell. The silver powder is conveyed and collected to the head of the electrolytic bath by the conveyor belt, and then the silver powder is taken out and washed in a washing machine.

The original silver powder collecting device is fixed at the head of an electrolytic bath, after the electrolyzed silver powder is received into the collecting device by a conveyor belt, the electrolyzed silver powder needs to be manually shoveled into a silver powder hopper and then pulled into a front hand tool of a washing machine to be washed in the washing machine, the silver powder loading amount of the silver powder hopper of each car is about 700kg, the time consumption of the transportation process is long, the subsequent processes are influenced, the labor intensity of workers is high, and the phenomenon of silver powder scattering and wasting is serious.
