METHOD AND DEVICE FOR SEPARATION OF METAL SHELLS FROM BASES OF ANODES, AND NAMELY ANODES USED FOR PRODUCTION OF ALUMINIUM BY MEANS OF FIRING ELECTROLYSIS Russian patent published in 2013 - IPC C25C3/12 

FIELD: metallurgy.

SUBSTANCE: method involves the following stages: a) a foot of an anode rod is arranged between a locking device and an action device; with that, the action device can be moved by means of an actuation mechanism in the direction of the locking device that encloses at least partially each of n nipples of the anode rob and represents a thrust surface locking the translational movement of the corresponding cast-iron cast, b) the action is moved in the direction of the locking device so that the action device can come into contact with the foot of the anode rod and can carry it away up to the moment when the foot of the anode comes into contact with the locking device, c) movements of the action device are continued so that each cast-iron cast locked with the thrust surface related to it can be disconnected from the corresponding nipple, and d) the action device is stopped and drawn back. With that, the locking device is used, which contains at least two thrust surfaces separated from each other with such a distance in axial direction so that cast-iron casts locked by means of the first thrust surface can be disconnected from round electrodes until other cast-iron casts are locked with other thrust surface.

EFFECT: possibility of separation of cast-iron casts and nipple foot of the anode rod per one step using one device without any anode damage.
