CHISEL ALIGNMENT UNIT FOR CRUST BREAKING FACILITY

摘要

The invention relates to a chisel alignment unit for a facility for breaking the crust of solidified electrolyte on an electrolytic cell, in particular on a cell for producing aluminum. A mechanically stable alignment box extends from the under side of the chisel in its non-working position to the piston rod. The chisel features at least one vertical alignment surface which is in contact with at least one alignment roll mounted on the alignment box by means of roller bearings. A wiper for removing electrolyte from the chisel is mounted below the alignment rolls and extends over the full width of the alignment surface or surfaces.
