Title
(EN) METHOD AND APPARATUS FOR PREPARING A MOTHER PLATE OF A PERMANENT CATHODE FOR AN ELECTROLYTIC PROCESS
(FR) PROCÉDÉ ET APPAREIL POUR PRÉPARER UNE PLAQUE MÈRE DE CATHODE PERMANENTE DESTINÉE À UN PROCESSUS ÉLECTROLYTIQUE
Abstract
(EN)
The invention relates to a method and an apparatus for preparing a mother plate (1) of a permanent cathode (2) to be used in a process for electrolytic recovery of metal such as metal electrorefining or metal electrowinning. The apparatus comprises a holding means (8) for releasable holding the permanent cathode (2), a measurement means (4) for measuring a shape of the mother plate (1) to obtain measurement data, a calculating means functionally connected with the measurement means (4) and configured for calculating geometric deviation of the mother plate (1) in comparison to a predefined reference shape by using said measurement data measured by said measurement means (4), and a pressing means (3) functionally connected with the calculating means and configured for automatically locally pressing the mother plate (1) in accordance with the calculated geometric deviation of the mother plate (1) to plastically deform the mother plate (1).
(FR)
L'invention concerne un procédé et un appareil pour préparer une plaque mère (1) de cathode permanente (2) utilisée dans un processus de récupération électrolytique de métal, tel qu'un raffinage ou une extraction électrolytique de métal. L'appareil comprend : un moyen de support (8) destiné à supporter la cathode permanente (2) de manière libérable, un moyen de mesure (4) destiné à mesurer la forme de la plaque mère (1) afin d'obtenir des données de mesure, un moyen de calcul fonctionnellement relié au moyen de mesure (4) et conçu pour calculer une déviation géométrique de la plaque mère (1) par rapport à une forme de référence prédéfinie au moyen des données de mesure mesurées par le moyen de mesure (4), et un moyen de pressage (3) fonctionnellement relié au moyen de calcul et conçu pour presser automatiquement et localement la plaque mère (1) en fonction de la déviation géométrique calculée de la plaque mère (1) afin de déformer plastiquement ladite plaque mère (1).
