COVER FOR ALUMINIUM ELECTROLYSER HAVING BAKED ANODES Russian patent published in 2015 - IPC C25C3/08 

FIELD: electricity.

SUBSTANCE: cover comprises horizontal plating made with flat-topped windows for anode holders and flat-topped frame installed over each flat-topped window at end and lateral sides respectively, a sealing plank fixed rigidly at the end surface of flat-topped window, guides fixed rigidly at lateral sides of the flat-topped window and the flat-topped frame is fixed in the above guides so that it can move inside them. The flat-topped frame and the sealing plank are made of flexible sealing element fixed with its one end between the lower and upper clamp plates so that unfixed side of the flexible sealing element may be deformed and a gap between the flat-topped window and anode holder can be overlapped. The upper and lower plate of the flat-topped frame and the sealing plank are made of light non-magnet metals and alloys. The flexible sealing element is made of multilayer textile material laid in one or several layers. The flat-topped frame has a handle. The lower clamp plate is thicker and longer than the upper clamp plate, and the plates and the sealing element are coupled by screws.

EFFECT: improved leak tightness of the electrolyser and exclusion of risk of its mechanical damage at anode replacing.
