Definitions

  • the invention relates to the production of aluminum by igneous electrolysis according to the Hall-Héroult method. It relates more particularly to service modules used in aluminum production plants.
  • Aluminum is produced industrially by igneous electrolysis in electrolysis cells according to the well-known Hall-Héroult process.
  • the plants contain a large number of electrolysis cells arranged in line, in buildings called halls or electrolysis rooms, and electrically connected in series using connecting conductors.
  • the cells are generally arranged to form two or more parallel lines that are electrically bonded together by end conductors.
  • an electrolysis plant requires interventions on the electrolysis cells including, in particular, the replacement of spent anodes with new anodes, the removal of liquid metal from the cells and the removal or addition of electrolyte.

  • These service units are often referred to as “electrolysis service machines” or "M.S.E” ("PTA” or “Pot Tending Assembly” or "PTM” or “Pot Tending Machine” in English).
  • the electrolysis cells are arranged as close as possible to each other and close to one of the lateral sides of the rooms.
  • electrolysis and a traffic lane as narrow as possible is arranged near the other lateral side of the rooms.
  • This provision requires that the distance between the walls of the electrolysis room and the limits of the working area of each of the tools of the service machines is as small as possible, especially for access to the electrolysis cells. This distance is called "tools approach”.
  • the position of the cells in the electrolysis room and the total area of the room that results depend substantially on the volume occupied by the service machines and the possibilities of approach and movement of their tools.
  • the known service modules occupy a large volume which prohibits a reduced approach to the sides of the electrolysis rooms, including the lateral sides, and which substantially limits their movements near these sides.
  • the volume of the modules can be reduced by a reconciliation of the tools.
  • this solution can increase the risk of damage to tools during maintenance operations.

It also gives the tools a limited independence of movement, while avoiding that they collide and that the jolts suffered by one of the tools have a direct impact on the other tools.
  • a technical problem of the service module of the prior art is to further minimize the volume under the chassis of said module, including the height under the chassis of the service module, and the volume of the space covered by the entire service module when rotating its rotating part.

  • any movement of the barrel 39 of a telescopic arm and of the movable part 79 integral with said barrel is accompanied by a deformation of the deformable part 81 by compressing the spring 85 by means of one or the other of the annular parts 89, 90 and movable buffer 87, 88 on which slides said annular piece.
  • this same movable bumper 87, 88 is detached from the wall 83, 84 secured to the first support structure 35, while the opposite movable bumper 88, 87 relies even more strongly on the other wall 84, 83 integral with this same supporting structure.
  • the moving part 79 and the barrel 39 of the telescopic arm are then returned to their initial position thanks to the spring 85. In this way, the range of tolerance of the amplitude of the pendular movements of the barrel 39 of each telescopic arm is even better controlled.
