Long-acting composite-basket anode combination device

Abstract

A long-acting composite-basket anode combination device comprising an outer frame for combination, two or more composite-basket anodes that allow feeding in batches, and an insoluble anode plate electrically connected with a power supply and mounted on each of the composite-basket anodes; the two or more composite-basket anodes are fixed on the outer frame for combination through a fixing device, respectively, the composite-basket anode includes a basket body, a plug-in strainer and a large-hole pressing plate; the large-hole pressing plate is fitted on both sides of the basket body and fixing the strainer inside the basket body to form a feed bin with an upper end opening. The present invention combines the soluble anode electrolytic refining principle with the two cathode metal production processes, and thus achieving one-step electrolytic refining.
