Definitions

  • the present invention relates to the general field of operation management an aluminum production facility, and more specifically an installation implementing the now widely used technique of igneous electrolysis.
  • It relates more particularly to a lifting and handling unit, while particularly intended to be used during metal casting operations or alumina, and handling of the lifting beam of the anode frames as well as various auxiliary handling associated with the operation of the electrolysis tanks.
  • the production of aluminum by igneous electrolysis implements the electrolysis of alumina in a molten cryolite bath according to the reaction:
  • This reaction uses a melt comprising a mixture of cryolite and alumina, the temperature of which is generally above 800 ° C. take in account the energies implemented and in order to minimize the losses inherent in the phases restart, the aluminum production facilities implementing this technology, generally operate continuously at the level of of aluminum, the number and dimensions of which are based on the one hand, the amperage available from the direct current feeding the tanks, and secondly, from the quantity of desired production.
  • facilities are frequently organized in such a way that they present two series of tanks mounted parallel to each other, installed within the same building or in separate buildings, but symmetrically with respect to a central aisle intended in particular to allow the handling of the ladle containing molten alumina intended to fill the electrolytic tanks, and other part intended for the handling of receiving pockets of molten aluminum obtained by electrolysis.
  • a trolley of casting for handling the ladle.
  • This casting carriage is equipped with a particular guidance system for handling said pocket with a capacity of typical lifting between 20 and 40 tons depending on the amperage of the tanks.
  • the installations in question also have handling, intended inter alia to operate a beam lifting frames anodic, raised at both ends, so that usually two of these type of trolley are implemented, with a typical capacity of between 10 and 20 tons.
  • This lifting anodic frames said frames being intended to receive and maintain within tanks the carbon anodes, is necessary as and when the wear of the anodes in the process of electrolysis and, still for the purpose of the continuity of the process.
  • a ferry that is, a device capable of to allow the displacement of a crane from a series of tanks to the series of tanks parallel, it can not be considered to operate a right bridge on a series left and vice versa.
  • One of the objectives of the present invention is to reduce the costs of production and operation of aluminum production facilities. To this end, it aims to allow use indifferently on one or the other of said series of vats Parallels of the ladle handling and lifting bridges anodic.
  • Another object of the present invention is to allow, by design said bridge, to reduce the congestion generated and thereby reduce the costs inherent in civil engineering.
  • Another object of the invention is also to lighten the structure of the bridges placed in in order to optimize their service life and consequently reduce the costs of manufacturing.
  • the invention therefore relates to a unit for lifting and handling loads within of an igneous electrolysis plant, said installation comprising at least one series of electrolytic cells in series and being provided with a track intended to allow the displacement of at least one traveling crane at above said series of tanks, and intended to allow the realization of different functions necessary for the implementation of said installation.
  • This lifting and handling unit constituting one of said overhead cranes, and on which are likely to move in a direction perpendicular to the translation of the unit, at least two lifting and handling assemblies mounted each on a trolley, is characterized in that said trolleys are susceptible to translate on said unit one above the other to allow their crossing respective.
  • the invention proposes a lifting and handling unit allowing, by the possible crossing of the two carriages that it comprises, a indifferent use on one or the other series of tanks mounted symmetrically compared to the central aisle.
  • the raceways of the two carts are coplanar.
  • the installation comprises two series of electrolysis tanks symmetrical with respect to the central aisle allowing the handling of the ladle and, the characteristic unit of the invention is capable of moving from a series of tanks at the level of the symmetrical series by means of a transhipment bridge.
  • one of the trolleys is intended for handling the casting ladle and the other is intended for auxiliary work and also for lifting anodic frames.
  • the unit can also accommodate two trolleys for work auxiliaries and the lifting of the anode frames.
  • the trolley handling casting moves at the level of internal raceways and the at least one auxiliary carriages at level of external raceways.
  • the auxiliary trolley (s) moves to top of the ladle handling trolley.
  • said carriages move below the handling trolley of the ladle.
  • Figure 1 a schematic view of a series of electrolysis tanks (1) for the production of aluminum according to the so-called method of igneous electrolysis.
  • These tanks are installed in an installation including two series of tanks parallel and symmetrical with respect to a central aisle (6), at the level of which are located on the one hand, an alumina supply device of said tanks, and on the other hand, the implementation of a system for capturing and treating fumes, in particular gases resulting from the reaction of electrolysis (in particular monoxide and dioxide carbon, oxygen, as well as fluorinated emanations).
  • These tanks are substantially identical to each other and each comprise an access cover (2) inside the tank, in particular at the molten electrolysis bath proper, thus freeing access to the carbon anodes (3).
  • the aforementioned fume collection and treatment system is fed from pipes (4) emanating from said tanks.
  • this series of tanks is overcome of a rolling path (5) on which one or more of cranes, such as for example the overhead traveling crane (7) constituting the handling and lifting according to the invention, and shown in more detail at the level of Figure 2.
  • cranes such as for example the overhead traveling crane (7) constituting the handling and lifting according to the invention
  • This crane (7) moves on the raceway (5) by means of rollers (8), whose motorisation has not been represented so as not to unnecessarily FIGS.
  • raceways (9) and (10) are intended to receive respectively a carriage (11) hereinafter referred to as a casting carriage, and one or two carriages (12) and (13) hereinafter referred to as auxiliary carriages or frame lifting carriages anodic.
  • the trolleys respectively casting (11) and lifting frames anodes (12, 13) can be crossed without hindrance, of course as long as the carriage superior does not have a suspended load.
  • the casting carriage (11) has been described in more detail with reference to FIG.
  • This one basically consists of a U-shaped chassis (15) resting on the road rolling (9) by means of rollers (14), and in particular by means of two sets of rollers parallel (14).
  • the motorization system of these rollers has not been shown in order not to not overload the figures unnecessarily.
  • This casting carriage (11) comprises a lifting device represented briefly and in particular the motorization (16) appears in Figure 3.
  • This carriage is intended to take charge of the ladle (23) (FIGS. 6 and 7), allow it to perform a translation so as to allow the filling of the ladle through a pipe (24) which is immersed in the tank (1).
  • the liquid metal is sucked by a vacuum system connected to the pocket, installed on the trolley, or coming directly from the building.
  • FIG. 4 also shows in greater detail the carriage auxiliary or lifting carriage of the anode frames (12, 13).
  • carriages since the unit advantageously comprises two, are constituted a chassis (17) resting on the tracks (10), parallel, coplanar and external to the tracks (9), by means of rollers (18) motorized by motors (19).
  • auxiliary carriages (12, 13) are also provided with lifting means.
