Title (EN) ELECTROLYTIC CELL WITH IMPROVED POWDER FEED DEVICE
(FR) CELLULE ELECTROLYTIQUE DOTE D'UN DISPOSITIF D'ALIMENTATION EN POUDRE AMELIORE
Abstract:
(EN) A device for intermittently supplying powder material (65) to a plurality of feed pipes (52) for feeding batches of the powder material (65) to different areas of a molten electrolyte (5) in a metal electrowinning cell comprises an arrangement (54, 55, 56a, 56b, 57, 58) for metering quantities of powder material and for intermittently dropping the metered quantities over at least one inclined and/or upright dividing surface (51), for instance having a conical or pyramidal shape. Each metered quantity of the powder material (65) is divided as it drops over the dividing surface(s) (51) into a plurality of batches which correspond to said plurality of feed pipes (52) and which are directed to said corresponding feed pipes (52).
(FR) L'invention concerne un dispositif conçu pour fournir, par intermittence, un matériau en poudre (65) à une multitude de tuyaux d'alimentation (52) afin de fournir des charges de matériau en poudre (65) à différentes zones d'un électrolyte fondu (5) dans une cellule d'extraction électrolytique de métal. Le dispositif décrit dans cette invention comprend un dispositif (54, 55, 56a, 57, 58) permettant de mesurer des quantités de matériau en poudre et de déverser, par intermittence, les quantités mesurées sur au moins une surface de séparation (51) inclinée et/ou verticale présentant une forme conique ou pyramidale. Chaque quantité de matériau en poudre (65) mesurée est séparée en une multitude de charges au fur et à mesure que ledit matériau en poudre se déverse sur la ou les surfaces de séparation (51); ces charges correspondent aux multiples tuyaux d'alimentation (52) et sont acheminées vers eux.
