Abstract:
An apparatus for removing an encrustation from a spent carbon anode having at least one carbon block stub extending along a first plane, said apparatus comprising:a drive motor; a shaft rotatably coupled to said drive motor, said shaft positioned such that it extends along a second plane substantially orthogonal to the first plane; an elongated flailing element attached to said shaft at a location remote from said drive motor, said elongated flailing element constructed and arranged to rotate on said shaft once said shaft is rotated by said drive motor; and a mechanism cooperating with said shaft to selectively urge said shaft toward and away from the first plane such that said shaft remains substantially orthogonal to the first plane, wherein said flailing element abrades the encrustation from a surface of the spent carbon anode that extends along a third plane substantially orthogonal to the first plane.
