ANODE KETTLE FOR ELECTRO-SEPARATION OF NON-FERROUS METALS Russian patent published in 2009 - IPC C25C7/02 C25C1/08 C25C7/04 

FIELD: metallurgy.

SUBSTANCE: invention relates to structures of diaphragm cells for electrolytic extraction of nickel from water solutions, particularly anode kettle. Anode kettle for electro-separation of non-ferrous metals by means of electrolysis in bath, allowing cathode chamber with catholyte, containing rigid-jointed framework, diaphragm bag, insoluble anode, contrivance for prevention of anode touch to diaphragm bag, facility for anolyte withdrawal and extracted on anode gaseous substances ensured by depression, implemented in the form of connecting pipe with inner diametre 5-12 mm, rigid in framework of anode kettle to bottom hole edge of connecting pipe is at the distance h from top edge of the kettle, defined from the formula: h=a+b, where a - distance between kettle edge to the level of catholyte in bath; b - level difference between catholyte and anolyte. Device preventing touch of anode with diaphragm bag is implemented in the form of grid from vertically located rods of thickness k=10-15 mm, manufactured from dielectric material and fixed on two horizontal abutment blocks with interval equal to 10*k.

EFFECT: providing of exclusion of anode touch to diaphragm bag and defined level difference between catholyte and anolyte.
