Title (EN) ELECTROLYTIC CELL FOR ALUMINUM PRODUCTION, WITH INDIVIDUAL ANODE DRIVES
(FR) CELLULE ÉLECTROLYTIQUE POUR LA PRODUCTION D'ALUMINIUM, AVEC ENTRAÎNEMENTS D'ANODES INDIVIDUELS
Abstract:
(EN) This superstructure comprises a frame (102) of substantially rectangular shape, an anode beam (104) fixed with respect to said frame, said superstructure comprising a plurality of anode holders (4A-4N, 6A-6N) each comprising holding means (130) for holding a respective suspended anode (1A-1N, 2A-2N) of said cell, said superstructure comprising also moving means (10, 12, 14, 15, 16, 17, 21A-21N, 31A-31N, 22A-22N, 32A-32N) adapted to move one single anode holder independently from the others, along a substantially vertical direction, said moving means comprising drive means (10), as well as transmission means (12, 14, 15, 6, 17, 21A-21N, 31A-31N, 22A-22N, 32A-32N), for transmitting movement imparted by drive means to each holder. According to the invention, each holder (4A-4N, 6A-6N) is slidably mounted into a respective pocket or guide (60A-60N, 70A-70N), provided in said anode beam (104). This makes it possible not to substantially increase the global footprint of the whole superstructure. Moreover, it makes it possible to guide said holders and, as a consequence, the anodes attached thereto during their vertical motion. This ensures a safe and efficient operation of the cell.
(FR) Cette invention concerne une cellule électrolytique comprenant une superstructure constituée d'un cadre (102) de forme sensiblement rectangulaire, d'un faisceau d'anodes (104) fixé par rapport audit cadre, où ladite superstructure comprend une pluralité de porte-anodes (4A-4N, 6A-6N) doté chacun de moyens de maintien (130) pour maintenir une anode respective (1A-1N, 2A-2N) de ladite cellule en suspens, et comprend également des moyens de déplacement (10, 12, 14, 15, 16, 17, 21A-21N, 31A-31N, 22A-22N, 32A-32N) conçus pour déplacer un seul porte-anode à la fois indépendamment des autres, dans un sens sensiblement vertical, lesdits moyens de déplacement comprenant des moyens d'entraînement (10), ainsi que des moyens de transmission (12, 14, 15, 17, 21A-21N, 31A-31N, 22A-22N, 32A-32N), pour transmettre le mouvement communiqué par les moyens d'entraînement à chaque porte-anode. Selon l'invention, chaque porte-anode (4A-4N, 6A-6N) est monté coulissant dans une poche ou un dispositif de guidage respectif (60A-60N, 70A-70N) dudit faisceau d'anodes (104), ce qui permet de ne pas augmenter sensiblement la surface au sol globale de la superstructure dans son ensemble. De plus, la superstructure selon l'invention permet de guider lesdits porte-anodes et, par voie de conséquence, les anodes fixées à ceux-ci pendant leur déplacement vertical pour un fonctionnement sûr et efficace de la cellule.
