ELECTROLYZER FOR ELECTROCHEMICAL DEPOSITION OF COPPER Russian patent published in 2003 - IPC

FIELD: non-ferrous metallurgy, specifically, electrochemical deposition of copper for manufacture of quality articles for various branches of industry. SUBSTANCE: electrolyzer includes body of bath, anodes, cathodes, pipe-line system to feed electrolyte, pocket for waste electrolyte. Pipe-line system to feed electrolyte is fitted with ejector collector with branch pipes installed in bath on side of face wall at level of upper edges of electrodes or with additional autonomous pipe-line. Holes are drilled in branch pipes or in additional autonomous pipe-line. Invention makes it feasible to improve technical-economical indices of technological process of copper deposition thanks to employment of structural members to supply newly made electrolyte to depleted sections of electrolysis bath or thanks to special output of depleted electrolyte from interelectrode space of upper level of bath and subsequent continuous equalization of chemical composition of electrolyte over entire height of interelectrode space. EFFECT: reduced energy consumption, increased current efficiency and anode scrap, improved quality of cathode copper. 7 cl, 2 dwg, 1 tbl
