CLOSURE HEAD OF ELECTROLYTIC CELL WITH HORIZONTAL MERCURY-POOL CATHODE Russian patent published in 2009 - IPC C25B1/40 C25B9/14 

FIELD: metallurgy.

SUBSTANCE: invention relates to field of electrochemical manufacturing of chlorine and caustic soda and can be used in electrolytic cells with horizontal mercury-pool cathode. Electrolytic cell closure head with horizontal mercury-pool cathode contains plate of carbon steel with holes for current contact jaw, barrier sheet of fluoroplastic-4 with holes for current contact jaws, located on the bottom plane of plate, bush of fluoroplastic-4, installed into coaxial holes for current contact jaws in plate and barrier sheet, flanges, located on barrier sheet coaxial to bushes, packing made of expanded fluoroplastic-4, located in joints - barrier sheet with nave collar and nave collar with flange, herewith flanges are connected to fasteners with plates. Flanges are implemented from carbon steel and coated by fluoroplastic-4. In proposed structure of head plate is protected against effect of operating environment of electrolytic cell by details of fluoroplastic-4, allowing better corrosion resistance in comparison with gum.

EFFECT: increasing of head durability.
