The invention relates to structural components of cathode devices in electrolytic cells for the production of aluminium. The seal comprises a device connected to a lined cathode shell having apertures for the passage of cathode rods, which device, located on the face of the electrolytic cell, is intended to house a sealing means and is made from an elastic, gas-proof and heat-proof material in the form of a sleeve that is hermetically connected by one end to the cathode shell. A plate with an opening is disposed on the inner side of the aperture for the passage of cathode rods, around the periphery thereof, and the sealing means, which is disposed in the gap formed by the cathode rod and the wall of the cathode shell, allows the cathode rod to slide relative to the cathode shell while ensuring that the seal remains tight. The technical result is that of providing that the seal remains tight during any movement of the cathode rods when the aluminium electrolytic cell is in operation. |
