Electrolytic device

An electrolytic device, wherein said device comprises a tank adapted to contain electrolyte, flat electrodes which are stacked horizontally so as to rest one upon another under the action of gravity and at least a certain number of which are consumable, two successive electrodes being separated by spacer elements having the same thickness and formed of material which is inert to electrolysis so that the contact surfaces between the spacer elements and the electrodes permit substantially uniform erosion of the consumable electrodes over their entire surface and the spacing between two consecutive electrodes thus remains constant and wherein the spacer elements are constituted by balls having the same diameter, two consecutive electrodes being separated by at least three non-aligned balls.

An electrolytic device comprising a tank adapted to contain electrolyte, flat electrodes which are stacked horizontally and rest one upon another under the action of gravity, so as to define a top electrode and a lower electrode adapted to be connected to an external source of current, at least one of said electrodes being consumable, all of said electrodes being separated by spacer elements having the same thickness and formed of material which is insert to electrolysis, wherein each spacer element has a shape such that the contact surfaces between this spacer element and the corresponding electrodes permit substantially uniform erosion of the consumable electrode over their entire surface, whereby the thickness of the bed of electrolyte between two consecutive electrodes remains constant.
