Abstract

The disclosure provides an electrolytic cell sealed in gas-tight and liquid-tight fashion. The cell is comprised of a box-shaped cell tank open at its top and provided with at least one intake duct, at least one overflow duct and at least one discharge duct. A cover is placed on the cell tank and two opposed flanges receiving electrode supporting frames are secured to the inside of the cell tank near the upper end thereof. A chemically resistant and electrically insulating coating is applied to the inside of the cover and cell tank and a plurality of semi-circular recessed grooves spaced apart from each other are formed in the upper rim portion of at least one of the side walls of the cell tank, the recessed grooves receiving semi-circular current beams projecting outwardly. A first elastic packing structurally conformed to the upper rim portion of the cell tank including the recessed grooves is placed thereon and a second elastic packing arranged at the underside of the cover co-operates with the upper side of the current beam and the first elastic packing whereby the electrolytic cell becomes gas tightly sealed. A main current rail is arranged to run outside the cell tank lateral…
