ABSTRACT:
The present invention is a method and an apparatus for electrolyzing zinc.
The method comprises vertically disposing a rotatable disk made of an electrically conductive metal functioning as a cathode at least of which an outer periphery has an insulation covering; immersing the lower portion of the disk into an electrolyte; disposing a circular arc shaped gas permeable electrode functioning as an anode to be closely opposed to the lower portion of the expressed portion of the both sides of the rotatable disk in the electrolyte; operating the electrolysis with the supply of hydrogen; and peeling off the zinc foil deposited onto the exposed portion of the both sides of the rotatable disk with rotation of the disk. This method can be modified by replacing the rotatable disk with a rotatable drum.
The apparatus comprises a rotatable disk cathode made of an electrically conductive metal at least of which an outer periphery has an insulation covering and which is supported vertically and rotatably at the center of the electrolytic cell; a circular arc shaped gas permeable electrode functioning as an anode, and closely opposed to the lower portion of the both sides of the cathode, and fixed to the walls of the electrolytic cell; an electrolyte circulation path located at the desired portion of the anode; and a supply port and a discharge port for hydrogen located at the desired portion of the anodes. This apparatus can be modified by replacing the rotatable disk with a rotatable drum.
