FILTER PRESS DEVICE FOR ELECTRODEPOSITION OF METAL FROM SOLUTIONS, WHICH IS MADE UP OF SEPARATING ELEMENTS CONFORMED BY ION EXCHANGE MEMBRANES FORMING A PLURALITY OF ANOLYTE AND CATHOLYTE CHAMBERS, WHEREIN THE ELECTRODES ARE CONNECTED IN SERIES WITH AUTOMATIC DETACHMENT OF THE METAL PRODUCT

摘要

The present invention relates to a device for electroplating metal from acidic, neutral or basic solutions having a low or high content of metal dissolved therein. A device is provided for the electrolytic production of metal, in the form of electrolytic metal sheets free from imperfections and impurities. The filter press device is constructed from a plurality of cells connected in series electrically and in parallel hydraulically with the solution, each of the cells comprising, alternately, quadrilateral frames and ion-exchange membranes to form, alternately, anode and cathode compartments. Each compartment allows the free flow of liquid, given that each frame comprises an inlet and an outlet on the outer surface thereof and holes on the inner surface, anolyte or catholyte passing through each compartment and the electrolysed product being discharged from the anolyte compartment or from the catholyte compartment in the form of a metal or a metallic compound. All the electrodes, except the terminal electrodes, are bipolar and designed with a vertical base plate which has a side functioning as an anode with the respective anolyte in a cell unit, and functioning on the other side as a cathode with the respective catholyte in the adjacent cell unit. The outer sides of the terminal electrodes comprise electrical connections for the row of cells, such that the electrodes of adjacent base plates are intercalated without making direct electrical contact with each other, forming a packet of electrode plates.
