Description

Domaine de l'inventionField of the invention

L'invention concerne la production d'aluminium par électrolyse ignée selon le procédé de Hall-Héroult. Elle concerne plus particulièrement les machines de service sur pont roulant utilisées dans lesdites usines.The invention relates to the production of aluminum by igneous electrolysis according to the Hall-Héroult process. It relates more particularly to service machines overhead crane used in said factories.

Etat de la techniqueState of the art

L'aluminium métal est produit industriellement par électrolyse ignée, à savoir par électrolyse de l'alumine en solution dans un bain de cryolithe fondue, appelé bain d'électrolyte, selon le procédé bien connu de Hall-Héroult. Le bain d'électrolyte est contenu dans des cuves, dites « cuves d'électrolyse », comprenant un caisson en acier, qui est revêtu intérieurement de matériaux réfractaires et/ou isolants, et un ensemble cathodique situé au fond de la cuve. Des anodes en matériau carboné sont partiellement immergées dans le bain d'électrolyte. L'ensemble formé par une cuve d'électrolyse, ses anodes et le bain d'électrolyte est appelé une cellule d'électrolyse.Aluminum metal is produced industrially by igneous electrolysis, namely by electrolysis of alumina in solution in a molten cryolite bath, called bath electrolyte, according to the well-known Hall-Héroult process. The electrolyte bath is contained in cells, called "electrolysis cells", comprising a box in steel, which is coated internally with refractory and / or insulating materials, and a cathodic assembly located at the bottom of the tank. Carbon material anodes are partially submerged in the electrolyte bath. The unit formed by a tank electrolysis cell, its anodes and the electrolyte bath is called an electrolysis cell.

Les usines contiennent un grand nombre de cellules d'électrolyse disposées en ligne, dans des bâtiments appelés halls ou salles d'électrolyse, et raccordées électriquement en série à l'aide de conducteurs de liaison, de façon à optimiser l'occupation au sol des usines. Les cellules sont généralement disposées de manière à former deux ou plusieurs files parallèles qui sont électriquement liées entre elles par des conducteurs d'extrémité. Le courant d'électrolyse passe ainsi en cascade d'une cellule à la suivante.The factories 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, so as to optimize floor space factories. The cells are usually arranged so as to form two or several parallel lines which are electrically linked together by conductors end. The electrolysis current thus cascades from one cell to the next.

En fonctionnement, une usine d'électrolyse nécessite des interventions sur les cellules d'électrolyse parmi lesquelles figurent, notamment, le remplacement des anodes usées par des anodes neuves, le prélèvement de métal liquide des cellules et les prélèvements ou ajouts d'électrolyte. Afin d'effectuer ces interventions, les usines les plus modernes sont équipées d'une ou plusieurs unités de service comprenant un pont mobile qui peut être translaté au-dessus des cellules d'électrolyse, et le long de celles-ci, et un module de service comprenant un chariot et des organes de manutention et d'intervention (souvent appelés « outils »), tels que des pelles et des palans, et apte à être déplacé sur le pont mobile. Ces unités de service sont souvent appelées "machines de service électrolyse" ou "M.S.E" ("PTA" ou "Pot Tending Assembly" ou "PTM" ou "Pot Tending Machine" en langue anglaise).In operation, an electrolysis plant requires interventions on the cells electrolysis which include, in particular, the replacement of anodes worn by new anodes, the removal of liquid metal from the cells and the electrolyte samples or additions. In order to carry out these interventions, the factories more modern are equipped with one or more service units including a movable bridge which can be translated above the electrolysis cells, and along these, and a service module comprising a trolley and handling and intervention (often called "tools"), such as shovels and hoists, and able to be moved on the mobile bridge. These service units are often called "electrolysis service machines" or "M.S.E" ("PTA" or "Pot Tending Assembly "or" PTM "or" Pot Tending Machine "in English).

Les capacités de mouvement des unités de service connues sont toutefois limitées, notamment à cause des câbles d'alimentation électriques qui ne permettent que des mouvements linéaires ou rotatifs limités.The movement capacities of known service units are however limited, in particular because of the power supply cables which only allow limited linear or rotary movements.

La demanderesse a donc recherché des unités de service qui permettent d'éviter ces inconvénients tout en restant fiables.The applicant has therefore sought service units which make it possible to avoid these disadvantages while remaining reliable.

Description de l'inventionDescription of the invention

L'invention a pour objet un dispositif de liaison mécanique et électrique rotatif entre un module de transport, typiquement un chariot, et des organes de manutention et d'intervention d'une usine de production d'aluminium par électrolyse ignée, caractérisé en ce qu'il comprend un châssis dit "fixe" muni d'un moyeu ou arbre droit, un manchon entourant le moyeu et apte à tourner autour de celui-ci, un premier et un deuxième châssis dits "rotatifs" aptes à tourner autour du manchon, des contacts électriques glissants rotatifs entre les châssis et des systèmes d'entraínement pour provoquer la rotation des châssis les uns par rapport aux autres autour d'un axe commun.The subject of the invention is a rotary mechanical and electrical connection device between a transport module, typically a trolley, and handling components and intervention of an aluminum production plant by igneous electrolysis, characterized in that it comprises a so-called "fixed" chassis provided with a straight hub or shaft, a sleeve surrounding the hub and able to rotate around it, a first and a second so-called "rotary" chassis able to rotate around the sleeve, contacts electric rotary sliding between the chassis and drive systems for cause the chassis to rotate relative to each other about an axis common.

Plus précisément, le dispositif de liaison mécanique et électrique rotatif selon l'invention est caractérisé en ce qu'il comprend :

  • un châssis dit "fixe" comprenant un moyeu ou arbre dit "central" définissant un axe de rotation,
  • un manchon entourant ledit moyeu et apte à tourner autour de celui-ci et autour dudit axe de rotation,
  • un premier châssis dit "rotatif" tournant avec ledit manchon et apte à tourner autour de l'axe de rotation,
  • un deuxième châssis dit "rotatif" apte à tourner autour dudit manchon et de l'axe de rotation,
  • une première pluralité de contacts électriques glissants rotatifs dont un membre, destiné aux raccordements à des conducteurs extérieurs, est fixé au châssis fixe et l'autre membre, destiné aux raccordements à des conducteurs du système susceptibles d'être entraínés en rotation, est fixé au manchon,
  • une deuxième pluralité de contacts électriques glissants rotatifs dont un membre est fixé au deuxième châssis rotatif et l'autre membre est fixé au manchon, chaque membre étant destiné aux raccordements à des conducteurs du système susceptibles d'être entraínés en rotation,
  • un premier système d'entraínement apte à provoquer la rotation du premier châssis rotatif autour dudit axe de rotation,
  • un deuxième système d'entraínement apte à provoquer la rotation du deuxième châssis rotatif autour dudit axe de rotation.
More specifically, the rotary mechanical and electrical connection device according to the invention is characterized in that it comprises:
  • a so-called "fixed" chassis comprising a so-called "central" hub or shaft defining an axis of rotation,
  • a sleeve surrounding said hub and able to rotate around it and around said axis of rotation,
  • a first so-called "rotary" chassis rotating with said sleeve and able to rotate about the axis of rotation,
  • a second so-called "rotary" chassis able to rotate around said sleeve and the axis of rotation,
  • a first plurality of rotary sliding electrical contacts, one member, intended for connections to external conductors, is fixed to the fixed frame and the other member, intended for connections to conductors of the system capable of being driven in rotation, is fixed to the muff,
  • a second plurality of rotary sliding electrical contacts, one member of which is fixed to the second rotary chassis and the other member of which is fixed to the sleeve, each member being intended for connections to conductors of the system capable of being rotated,
  • a first drive system capable of causing the rotation of the first rotary frame around said axis of rotation,
  • a second drive system capable of causing the rotation of the second rotary frame around said axis of rotation.

Ainsi, les deux châssis rotatifs et le manchon du dispositif de liaison de l'invention sont destinés à tourner autour d'un axe de rotation commun, qui est typiquement vertical en utilisation, et indépendamment l'un de l'autre. La rotation des châssis et du manchon est alors dite "coaxiale". Le manchon est entraíné en rotation par le premier châssis rotatif, typiquement par l'intermédiaire d'un moyen mécanique, tel qu'un doigt.Thus, the two rotary chassis and the sleeve of the connection device of the invention are intended to rotate around a common axis of rotation, which is typically vertical in use, and independently of each other. The rotation of the chassis and sleeve is then called "coaxial". The sleeve is rotated by the first rotary chassis, typically by mechanical means, such as a finger.

Le dispositif de liaison selon l'invention permet une rotation angulairement illimitée entre les trois châssis, tout en assurant une liaison électrique permanente entre ceux-ci. L'indépendance de rotation des châssis augmente le confort et l'efficacité de l'opérateur. The connecting device according to the invention allows unlimited angular rotation between the three chassis, while ensuring a permanent electrical connection between them. The independence of chassis rotation increases the comfort and efficiency of the operator.
