Definitions

  • the invention concerns an interconnecting device intended to form part of an anode-cathode coupling device for a group of at least two electrolysis cells connected in series, and comprising a flexible conducting connection having one of its extremities electrically connected to and rigidly fixed on the cathode unit of a first cell, while the other extremity is provided with a first contact held by the effect of adequate mechanical pressure means against a second contact fixed on the removable anode assembly of a second cell connected in series with the first cell.
  • the device further comprises means for shortcircuiting the cell before removal of the anode assembly.
  • the present invention relates to an anode-cathode interconnection device or coupling device for electrolysis cells, connected in series so as to permit the use of the direct-current supply under the best possible economic conditions.
  • conductive bus-bars for example of copper or aluminium, assembled together by means of bolts, these bars joining together the cathode assembly of one cell to the anode assembly of the next following cell.
  • the present invention has for its object to remedy the disadvantages referred to above.
  • a further object of the present invention is to provide an interconnection device in which the electrical efficiency of the coupling obtained is high, due to the low voltage drops present in the said coupling.
  • the opening of the cells for the replacement of anodes, cleaning, operations of overhaul, or again for the localisation of faults in the event of a general shut-down of the installation is made easier and much more rapid due to the elimination of the conducting coupling bars and the numerous assembly bolts.
  • the anode-cathode interconnection coupling device ac- 3,453,198 Patented July 1, 1969 cording to the invention is essentially characterised by the fact that it is constituted by a conducting flexible connection, of which one extremity is coupled in a fixed manner to the cathode assembly of a cell, while on the other extremity is fixed a first contact maintained with suflicient mechanical pressure, by appropriate means, against a second contact rigidly fixed to the removable anode assembly of the next following cell.
  • the anode-cathode coupling device and the short-circuiting device are arranged on a common support.
  • a locking device associated with the short-circuiting device only permits the removable anode assembly to be lifted when the corresponding cell is effectively shortcircuited.
  • the contacts are made of a highly conducting metal and make it possible to obtain a minimum voltage drop.
  • the anode-cathode interconnection between two consecutive electrolysis cells is effected by a number of coupling devices according to the invention, the number of these devices being a function of the output of these cells:
  • the interconnected electrolysis cells coupled by means of the device according to the invention are of the type in which the anodes are fed by means of distribution bars and/or by means of a cover associated with the cell, the body of the cell itself being conducting or non-conducting.
  • FIG 1 shows in partial diagrammatic section a preferred form of construction of the interconnection device or coupling device according to the invention and its mounting between two cells of the above type.
  • FIG. 2 is a diagrammatic view on a larger scale of the anode-cathode interconnection coupling device, indicated generally by the reference I and electrically connecting the cathode of the cell C (not shown) to the anode assembly A of a cell C
  • the device I comprises a flexible connection 1 in conducting metal, for example of copper or aluminium in the form of braid or strip.
  • One extremity of the connection is electrically connected ice to the cathode of negative potential of the cell C
  • a contact 2 is fixed on the other extremity of the connection 1, for example by welding, and is brought against a contact 3 which is fixed to a supply bar 4 of the anodes at a positive potential.
  • the bar 4 is in turn supported by the cover 5 of the cell C
  • the pressure between the contacts 2 and 3 is obtained in this case by means of a spring 6 enclosed in a housing 7 which is fixed on the body of the cell with the interposition of an insulating plate 8.
  • An interconnection device intended for coupling together respectively the anode and cathode assemblies of at least two electrolysis cells connected in series, said interconnection device comprising:
  • a flexible electrical connection means having a first extremity rigidly fixed to and in contact with the cathode assembly of a first cell and a second extremity provided with a first contact;
  • elastic pressure means intended to apply said two contacts against each other with adequate mechanical pressure
