Copper electrolyte decoppering method by utilizing copper electrolytic residual anodes as cathodes and device thereof

Abstract

The invention relates to a copper electrolyte decoppering method by utilizing copper electrolytic residual anodes as cathodes and a device thereof. The copper electrolyte decoppering method comprises the following steps of: driving a vehicle to lift the copper electrolytic residual anodes out of an electrolytic cell in an electrolytic plant and feed to a copper electrolytic residual anode washing unit with polar plate selecting function; controlling an indoor operating staff to select qualified copper electrolytic residual anode plates and feeding to a residual anode online open channel by the copper electrolytic residual anode washing unit with polar plate selecting function; transporting out after the qualified copper electrolytic residual anode plates are suspended and tightly arranged; feeding to a decoppering plant by a fork truck; placing in a decoppering electrolytic cell; and introducing direct current to carry out decoppering impurity removal on electrolyte. Through the application of the method and the device, a working procedure of manufacturing starting sheets is not required, the qualified residual anodes are selected by the copper electrolytic residual anode washing unit with polar plate selecting function, and the copper electrolytic residual anodes are utilized for placing the starting sheets as cathode plates in the working procedure of decoppering, so that the decoppering purpose is achieved, and the method is low in production cost, high in efficiency and good in decoppering effect.

Description

technical field [0001] The invention relates to the technical field of copper electrolysis, in particular to a method and a device for removing copper from a copper electrolyte by using a residual anode of copper electrolysis as a cathode. Background technique [0002] At present, in the copper electrolysis workshop using the stainless steel cathode plate process, the decopper electrolytic cell in the copper electrolyte cleaning section generally uses the copper seed plate system starter as the cathode, and uses the copper starter as the cathode, and the starter often appears Cathode broken ears and lead anode ears burned, etc., and it is necessary to add the initial electrode production process, increase the lifting lug cutting machine, riveting earphones and corresponding workplaces, etc., which increases the manpower, material resources and resources of the copper electrolyte decopper process. financial resources.
