Definitions

  • the object of the present invention is to prevent breaking of the anodes during their manipulation, and the subject matter of the invention consists in a particular device for placing, transferring and removing the anodes in and from the cell without any risk of shock and deterioration, and for regulating the distance between the anode and the cathode of the cell.
  • this object is attained by means of a device for handling the anodes, in which the latter are rigidly fixed to cover plates which are fixed in their turn to supports resting by means of guide rollers on a guide way comprising: lower fixed guide elements located on both sides of the cell, parallelly to this latter; upper fixed guide elements located along both sides of each end portion of the cell; and intermediary connecting guide elements, connected by one end to the lower guide elements and capable of being moved at their other end from the level of the lower guide elements to the level of the respective upper guide elements, in such a manner as to connect both to each other.
  • the roller bearing surface of the guide elements such f. i. as rails, are provided, according to the invention, with arresting notches into which the rollers may penetrate.
  • the supports of the cover plates to which the anodes are fixed may be connected to the bearing rollers by means of regulating elements which afford the possibility of adjusting with precision the vertical distance between the cover plates and said rollers, and consequently the anodecathode' distance.
  • Figure l is a perspective view of one end portion of an electrolytic cell, one anode disconnected from the electric feeding device and ready for being removed from the cell.
  • Figure 2 shows the same anode lifted out from the cell and resting on one of the inclined guide ways, for being conducted towards an evacuation carriage (not shown).
  • Figure 3 shows diagrammatically a longitudinal vertical til 2,786,023 Patented Mar. 19, 1957 section through the device for vertical regulation of the position of the anodes.
  • the cell trough comprises a bottom 1 of electrically conducting material supporting the cathode, two lateral walls 2 protected by a coating of insulating material (not shown), and an end portion 3 provided with connecting branches 4 for supplying and removing the liquids and gases of electrolysis, and with an inspection window 5.
  • This cell trough unit is combined with guide ways for the introduction and the removal of the anodes, such guide ways comprising, according to the example'illustrated in the drawings, two guide elements, such as rails 6, supported by uprights 7 fixed on both sides of each end portion 3 of the cell, and guide elements, suchas rails 8, fixed to the cell bottom 1 on both sides of the cell by means of supports 9, the anodes moving along the cell on said rails by means of rolling devices as described below.
  • Each anode comprises a plurality of graphite plates 10 rigidly fixed to cover plates 11 by means of current conducting graphite studs 12 provided with metal terminals 13 which are in contact with bus bars 14.
  • the cover plates 11 are fixed to supports 15 which are provided with rollers 16 travelling on the above mentioned guide ways and combined with said supports by means of a mechanism for vertically adjusting the supports 15 with respect to the rollers 16, as will be described below.
  • said rail sections 17 serve to support the anode in working position, whereas in their inclined position 17 according to Figure 2, they may be used for removing the worn out anode at one end of the cell and for introducing a fresh anode at the other end of the cell.
  • the rail sections 17 rest on supports 18 fixed to the cell bottom 1.
  • the rails 8 and 17 are provided with notches 19 for receiving and retaining the rollers 16, thereby determining the position of the anodes within the cell in the longitudinal direction of the latter.
  • the distance between the anodes and the cathode may be modified by varying the height at which the cover plates are positioned with respect to their supporting rollers. It is obvious that in principle, known devices for regulating the distance between electrodes may be adapted to the supporting means according to the present invention.
  • the supports 15, to which the cover plates 11 are rigidly fixed are of tubular shape and rest at their end portions on pistons 23 which carry the rollers 16 and are slidably mounted in guiding chambers formed by cylindrical or parallelopipedic walls 24 fixed to the supports 15.
  • a pair of discs 20, 29 is rotatably mounted, the discs of each pair being connected to each other by a crank pin 21, each crank pin resting on the respective roller carrying piston 23.
  • Both disc and crank pin systems 2t), 20, 21 in each tubular support 15 are connected to each other by a rod 29, the end discs 20 being provided with square trunnions 22 which are accessible from 3 e su s ds by me ns of q kee nshi h device just described the uniform distance between the anodes, fixed to the cover plates 15, and the cathode can be adjusted with precision, by causing the system 29, 2.0, 21, 22 to rotate relatively to the system 15, 24, 23, 26 by means ,of a wrench.
  • each square head 22 there is fixed a sector (see also Figures 1 and 2) provided with an arcuate slot 30 cooperating with a pressure screw 26 which passes through said slot and is screwed into the corresponding wall portion 24.
  • the sector 25 may be provided with a graduation for determining the position of the anode with respect to the rails 8 and 17.
  • an elongated substantially horizontal electrolytic cell having end walls and parallel vertical side walls, cover plates having anodes depending therefrom, support means for said coverplates, said support means including rollers at the sides of said cover plates adjoining said vertical side walls, and guide means for receiving said rollers in rolling engagement therewith
  • said guide means including lower fixed guide elements extending longitudinally along said cell exteriorly of said side walls and having a guiding surface for engagement with said rollers, upper fixed guide elements secured at the end of said cell and having a longitudinal guiding surface disposed at a level higher than the guiding surface of said lower guide elements, and intermediate connecting guide elements, each intermediate element being hingedly connected at one end and being movable to extend between the end of one of said lower guide elements and the opposed end of one of said upper guide elements to provide continuity of guiding surfaces therebetween for conducting said rollers between said lower guide elements and said upper guide elements.
