This unit for the collection, cleaning and calibration of electrolysis pots and, in particular, of the anodic orifices, as the anodes of an installation for the production of aluminum by igneous electrolysis are replaced, comprises two buckets (16, 17) hinge-mounted at the level of the lower end of a chassis (10) movable in vertical displacement, the lower edge (31) of each of the said buckets (16, 17) being liable to be bestowed with a circular movement by means of a closing and opening connecting rod assembly (14, 14'). It additionally comprises a first chassis (10), referred to as the shovel-bearing chassis, joined to a vertical guide mast (5), and a second chassis (11), referred to as the buckets-supporting chassis, mechanically linked to the said shovel-bearing chassis (10), and liable to displacement relative to the latter, the said buckets-supporting chassis (11) integrating the connecting rod assembly for closing and opening the buckets (14, 14'), the said buckets (16, 17) being hinge-mounted at the lower end of this chassis.
Cette unité de collecte, de nettoyage et de calibrage des cuves d'électrolyse, et notamment des orifices anodiques lors du remplacement des anodes d'une installation de production d'aluminium par électrolyse ignée, comprend deux godets (16, 17) articulés au niveau de l'extrémité inférieure d'un châssis (10), mobile en translation verticale, le bord inférieur (31) de chacun desdits godets (16, 17) étant susceptible d'être animée d'un mouvement circulaire au moyen d'un embiellage de fermeture et d'ouverture (14, 14'). Elle comprend en outre un premier châssis (10), dénommé châssis porte-pelle, solidarisée à un mât de guidage vertical (5), et un second châssis (11), dénommé châssis support des godets, relié mécaniquement audit châssis porte-pelle (10), et susceptible de se translater par rapport à celui-ci, ledit châssis support des godets (11) intégrant l'embiellage de fermeture et d'ouverture des godets (14, 14'), lesdits godets (16, 17) étant articulés à l'extrémité inférieure de ce châssis.
