ABSTRACT:
Installation for removing zinc deposited by electrolysis aluminum plates. The installation includes a storage zone for zinc cathode (1), a zinc scraping zone (2) and a storage zone (3) for zinc-free cathodes, the cathodes being displaced consecutively from one zone to another. The scraping zone (2) has a horizontally acting lateral piercer (22) that separates the upper edge of the sheets of deposited zinc from the cathodes, and a vertically acting scraping device (23) for removing all the zinc sheets.
On one of their vertical sides, the cathodes have an upper zone of lesser thickness to which is fixed coatings (76) of dielectric material, whose surface is coplanar with that of the cathode plate (70).
