ABSTRACT:
The covering of an aluminium-producing electrolysis cell is made as a hood for gathering and extracting volatiles, mounted over the cell.
Provided at the edges of said hood are inclined lids interconnected with the levers of the drive shafts, as well as inclined guideways for said lids.
Each of said levers carries one of the arms of the double-arm angle hanger, said arm being arranged lengthwise said lever pivotally round the longitudinal axis thereof, while the other arm of said hanger is articulated to the top end face of the lid and with its loose end rests upon the adjacent lever.
Such a covering enables the electrolysis cell to be attended when its lids are partly raised which cuts down power consumption of the ventilation system and improves labour conditions of the attending personnel.
