An annular fully-sealed button-type electrowinning cell

Abstract

The invention discloses an annular totally-enclosed buckle type electrowinning cell, and belongs to the field of hydrometallurgy. The annular totally-enclosed buckle type electrowinning cell comprisesa supporting device, an outer shell, a cell body mechanism and an automatic buckling release device, wherein the supporting device comprises a ceiling and a support; the outer shell is arranged underthe ceiling; the cell body mechanism is arranged in the outer shell; the cell body mechanism comprises an upper cell body and a lower cell body which are annular; the upper cell body is provided witha positive plate fixed hanger and a negative substrate fixed hanger; the top ends of the positive plate fixed hanger and the negative substrate fixed hanger are respectively and fixedly connected with the ceiling, and a positive plate and a negative substrate are respectively arranged on the bottom ends of the positive plate fixed hanger and the negative substrate fixed hanger; the automatic buckling release device is arranged on the negative substrate; a feed opening and an oblique slide way are arranged on the bottom end of the lower cell body; the oblique slide way is communicated with theautomatic buckling release device. The annular totally-enclosed buckle type electrowinning cell disclosed by the invention is good in air tightness, and harmful as cannot spill; after a nickel bucklenegative substrate is repeatedly stripped, a gap cannot be generated between a conductive post and the negative substrate, electrolyte cannot permeate, and the problem of growing nodules is completely eradicated; the cell body is compact in structure, and the occupied space is small.

Description

technical field [0001] The invention belongs to the field of hydrometallurgy, and in particular relates to an annular fully-sealed button-type electrowinning cell. Background technique [0002] Hydrometallurgy is a process in which metal mineral raw materials are chemically treated or extracted with an organic solvent in an aqueous solution of an acidic medium or an alkaline medium, to separate impurities, and to extract metals and their compounds. In the existing process of extracting nickel by hydrometallurgy and forming nickel buttons, the electrowinning cell used is an open rectangular shell, and chlorine gas will be discharged in the air to damage human health; at the same time, the nickel button cathode substrate is repeatedly stripped Finally, a gap is likely to appear between the conductive column and the cathode substrate, resulting in the infiltration of the electrolyte and the growth of nickel tumors.
