ABSTRACT:
An apparatus for the precise adjustment of the anode plane of a cell for the production of aluminum by electrolysis of alumina dissolved in the molten cryolite of which the anodic system comprises a plurality of prebaked anodes arranged in two parallel lines and provided with suspension rods connected electrically to an anode bus bar which permits the positive intake of current. The apparatus comprises: a fixed gantry formed by at least one rigid horizontal beam provided with supports at its ends; a collective frame formed by two rigid horizontal elements each corresponding to a line of anodes, each supported by the fixed gantry via an assembly of rods and of levers which enable the two rigid elements to travel relative to the gantry in a rising or descending direction, while remaining horizontal; a means for controlling each assembly of rods and levers which is separate but can be coupled; a plurality of jacks for individually controlling the rise or descent of the anodes which are connected on the one hand to the collective frame and on the other hand to a plurality of small individual frames, electrical and mechanical connections between the small individual frames and the anode suspension frames; and the bus bars and the small individual frames being electrically connected.
