Unit for the collection, cleaning and calibration of electrolysis pots used for aluminium production

Unit for collection, cleaning and calibration of anodic orifices of electrolysis pots, as the anodes of an installation for the production of aluminum by igneous electrolysis are replaced, comprising:

• a shovel-bearing chasis having two buckets hinge-mounted at a level of a lower end of said shovel-bearing chassis, said shovel-bearing chassis being movable in a vertical direction, a lower edge of each of said buckets being moveable in a circular motion by a connecting rod assembly;
• said shovel-bearing chassis joined to a vertical guide mast;
• and
• a buckets-supporting chassis mechanically linked to said shovel-bearing chassis and movable relative to said shovel-bearing chassis said buckets-supporting chassis integrating the connecting rod assembly for closing and opening the buckets, said buckets being hinge-mounted at the lower end of said buckets-supporting chassis;
• and
• said shovel-bearing chassis and said buckets-supporting chassis being simultaneously movable to allow said lower edge of each of said buckets to move in a same horizontal plane relative to each other during the circular motion of said buckets.
