ANODE ROD TIGHTENING APPARATUS FOR ALUMINA ELECTROLYSIS CELLS

摘要

Improvements in the construction of adjustment devices for the anode axes on the main bars of the alumina electrolysis tanks, characterized in that an adjustment apparatus and a handling apparatus are combined, said adjustment apparatus comprising two articulated levers on a common axis, two nuts that rotate respectively on each of the levers, and a screw that comprises two opposite passage parts, which act on the nuts in order to move the levers closer or closer, each of which is provided with minus a transverse bar that presses on the anode axis when the levers are moved away, the common axis rests on two hooks attached to the main bar placed on either side of the anode axis, the apparatus also comprising a double gripper capable of grasping the common axis of the levers of the adjusting device, at each of its extremities that exceed this effect, hooks d e support, a wrench capable of acting on a screw head in an opposite step and a guide means along the anode axis.
