摘要
PROBLEM TO BE SOLVED: To provide a polishing device or pickling device for common conductors for electrolytic refining equipment capable of continuously and automatically polishing or pickling the sections for supporting the anode lugging molds or cathode starting plates of the common conductor installed on the side walls partitioning adjacent electrolytic cells of the electrolytic refining equipment to improve the electrolytic efficiency. SOLUTION: The polishing device of the common conductors 31 is constituted to polish the sections supporting the anode lugging molds or the cathode starting plates of the common conductors installed on the side walls 30a partitioning the adjacent electrolytic cells of the electrolytic refining equipment by a polishing means 12 while injecting dilute sulfuric acid or an electrolyte just prior to the placement of these anode lugging molds or the cathode starting plates. Since the polishing is executed just prior to the placement, the placing of the anode lugging molds or the cathode starting plates on the surfaces right after the polishing is made possible and the conduction defect may be averted. In addition, the polishing is executed while the dilute sulfuric acid or the electrolyte is injected and, therefore, the surfaces having the higher electrical conductivity are formed by dissolving the adhered solid metal salts, polishing dust or the like and the simultaneous replenishment of the acid in the electrolytic cells is made possible by returning the acid to the electrolytic cells.
