Clamping diaphragms or membranes in electrolytic cells.

摘要

A diaphragm- or membrane-electrolytic cell comprising a plurality of anodes and cathodes, a diaphragm or membrane between adjacent anodes and cathodes, and slotted diaphragm- or membrane-supports, wherein the diaphragms or membranes (6) are sealed to the lips (12) defining the slots in the supports by means of one or more clamps which provide an essentially leak-tight seal between the diaphragms or membranes and the lips on the supports. In a preferred embodiment the clamp comprises inner (30) and outer (31) flexible bands between which the assembly of diaphragm or membrane and lips are located and clipping device (32) in the form of a wire bent into a sinuous path providing shaped profiles, which device is applied over the assembled inner and outer bands such that alternate profiles or groups of profiles lie on opposite sides of the assembly.
