Un résultat que l'invention vise à obtenir est un dispositif qui puisse être, sans concession, utilisé sur un site industriel métallurgique.A result which the invention aims to obtain is a device that can be used without concession on a metallurgical industrial site.

D'autres résultats que l'invention vise à obtenir apparaítront à la lecture de la description qui suit.Other results that the invention aims to obtain will appear on reading the description which follows.

L'invention sera bien comprise à la lecture de la description ci-après faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement :

  • figures 1 à 3 : le dispositif vu en coupe selon un plan transversal et dans différentes attitudes de fonctionnement,
  • figure 4 : le même dispositif vu en coupe selon un plan longitudinal.
The invention will be clearly understood on reading the description below given by way of nonlimiting example with regard to the appended drawing which schematically represents:
  • FIGS. 1 to 3: the device seen in section along a transverse plane and in different operating attitudes,
  • Figure 4: the same device seen in section along a longitudinal plane.

En se reportant au dessin, on voit un dispositif 1 de traitement sous atmosphère contrôlée d'un matériau liquide 2, tel un métal à l'état liquide.Referring to the drawing, we see a device 1 of treatment under a controlled atmosphere of a liquid material 2, like a metal in a liquid state.

Bien que cela n'apparaisse pas de manière flagrante sur le dessin, le dispositif 1 est particulièrement, mais non exclusivement, adapté à l'affinage d'aluminium.Although it does not appear blatantly on the drawing, device 1 is particularly, but not exclusively suitable for aluminum refining.

De manière remarquable, le dispositif 1 met en oeuvre :

  • un réceptacle premier 3, d'un volume utile défini par au moins une face 3A d'une paroi 3B, destiné à contenir le matériau liquide 2 à traiter,
  • une enceinte 4, dite de confinement et d'un volume utile défini par au moins une face 4A d'une paroi 4B, reliée à un moyen 5 d'action sur la pression d'un fluide sensiblement gazeux qui s'y trouve, tel un corps à l'état gazeux et/ou vaporisé,
  • un réceptacle second 6, d'un volume utile défini par au moins une face 6A d'une paroi 6B, destiné à recevoir et contenir le matériau liquide 2 ayant subi un traitement de purification par passage dans l'enceinte 4 précitée, et
  • un moyen 7 de transfert, pour prélever le matériau liquide 2 dans le réceptacle premier 3 puis, le faire transiter dans l'enceinte 4 contre une surface 8 dite d'exposition sous la forme d'une couche 9 dont la face libre 9A est exposée dans l'enceinte 4 et finalement, l'évacuer vers le réceptacle second 6 après ce transit.
Remarkably, the device 1 implements:
  • a first receptacle 3, of a useful volume defined by at least one face 3A of a wall 3B, intended to contain the liquid material 2 to be treated,
  • an enclosure 4, called a confinement and of a useful volume defined by at least one face 4A of a wall 4B, connected to a means 5 for acting on the pressure of a substantially gaseous fluid therein, such a body in the gaseous and / or vaporized state,
  • a second receptacle 6, of a useful volume defined by at least one face 6A of a wall 6B, intended to receive and contain the liquid material 2 having undergone a purification treatment by passage through the aforementioned enclosure 4, and
  • a transfer means 7 for removing the liquid material 2 from the first receptacle 3 then passing it through the enclosure 4 against a so-called exposure surface 8 in the form of a layer 9 whose free face 9A is exposed in enclosure 4 and finally, evacuate it towards the second receptacle 6 after this transit.

Le moyen 5 d'action sur la pression d'un fluide sensiblement gazeux, tel un corps à l'état gazeux et/ou vaporisé, qui se trouve dans l'enceinte 4, consiste en un moyen 5 de pompage adéquate.The means 5 of action on the pressure of a fluid substantially gaseous, such as a gaseous body and / or vaporized, which is in enclosure 4, consists of a means 5 adequate pumping.

De manière remarquable, pour constituer le moyen 7 de transfert :

  • au moins celui dit premier des réceptacles dits premier et second, c'est à dire au moins celui des réceptacles qui est destiné à contenir le matériau liquide 2 à traiter par passage sur la surface 8 d'exposition, est porté par un moyen 7A de basculement en vue d'induire, par gravité, le déversement contrôlé dudit matériau liquide 2 qu'il contient par dessus un bord 3C sensiblement rectiligne et approximativement horizontal qu'il présente à cet effet,
  • c'est à ce bord 3C du réceptacle premier que se trouve raccordée au moins une surface 8 qui, constituant la surface 8 dite de d'exposition, d'une part, est générée par une ligne sensiblement rectiligne et parallèle au dit bord et, d'autre part, est également raccordée à un bord 6C, dit de déversement, sensiblement rectiligne et approximativement horizontal, quant à lui présenté par le réceptacle second 6,
  • au moins les deux réceptacles 3, 6 sont disposés de manière telle que le déversement contrôlé du matériau liquide 2 contenu dans le réceptacle premier 3 sur la surface 8 d'exposition induit la formation d'une couche 9 d'épaisseur E déterminée sur cette surface 8 et que, par cela, ledit matériau liquide 2 s'écoule vers le bord 6C sensiblement rectiligne et approximativement horizontal quant à lui présenté par le réceptacle second 6 de manière à s'écouler dans ce réceptacle 6.
Remarkably, to constitute the transfer means 7:
  • at least that said first of the so-called first and second receptacles, that is to say at least that of the receptacles which is intended to contain the liquid material 2 to be treated by passing over the exposure surface 8, is carried by a means 7A of tilting in order to induce, by gravity, the controlled pouring of said liquid material 2 which it contains over a substantially straight and approximately horizontal edge 3C which it presents for this purpose,
  • it is to this edge 3C of the first receptacle that there is connected at least one surface 8 which, constituting the so-called exposure surface 8, on the one hand, is generated by a substantially straight line parallel to said edge and, on the other hand, is also connected to an edge 6C, said to be of discharge, substantially rectilinear and approximately horizontal, meanwhile presented by the second receptacle 6,
  • at least the two receptacles 3, 6 are arranged in such a way that the controlled discharge of the liquid material 2 contained in the first receptacle 3 on the exposure surface 8 induces the formation of a layer 9 of thickness E determined on this surface 8 and that, by this, said liquid material 2 flows towards the edge 6C substantially rectilinear and approximately horizontal as for it presented by the second receptacle 6 so as to flow in this receptacle 6.

De manière remarquable, l'enceinte 4 de confinement est délimitée par une paroi 4B qui, en déterminant un certain volume au moins au dessus des deux réceptacles 3, 6 et de la surface 8 d'exposition, les coiffe de manière étanche.Remarkably, the confinement enclosure 4 is delimited by a wall 4B which, by determining a certain volume at least above the two receptacles 3, 6 and the exposure surface 8, covers them tightly.

Avantageusement, l'installation de l'invention permet qu'avant et/ou pendant le transfert du matériau liquide d'un réceptacle à un autre, ledit matériau puisse être traité selon une technique classique.Advantageously, the installation of the invention allows before and / or during the transfer of the liquid material from a receptacle to another, said material can be treated according to a classic technique.

Dans ce dispositif, on peut, par exemple, effectuer des opérations de décrassage, addition d'éléments, barbotage, par exemple avec un gaz neutre.In this device, one can, for example, perform scouring operations, addition of elements, bubbling, by example with neutral gas.

Pour constituer le moyen 7A de basculement :

  • les deux réceptacles 3, 6 ainsi que la surface 8 d'exposition qui les relie, sont solidaires d'une même structure 10,
  • cette structure 10 est mobile au moins autour d'au moins un axe 7D, dit de basculement, sensiblement parallèle au bord 3C de déversement du réceptacle premier 3 et ce, depuis une position première P1 dans laquelle le matériau liquide 2 est librement contenu par le réceptacle premier 3 vers une position seconde S1 dans laquelle, ledit matériau 2 est contenu par le réceptacle second 6 conséquemment à son déversement contrôlé du réceptacle premier 3.
To constitute the tilting means 7A:
  • the two receptacles 3, 6 as well as the exposure surface 8 which connects them, are integral with the same structure 10,
  • this structure 10 is movable at least around at least one axis 7D, known as the tilting axis, substantially parallel to the edge 3C for discharging the first receptacle 3, from a first position P1 in which the liquid material 2 is freely contained by the first receptacle 3 towards a second position S1 in which said material 2 is contained by the second receptacle 6 as a result of its controlled discharge from the first receptacle 3.

La construction du dispositif de l'invention peut donc faire appel à des organes simples dont l'assemblage peut être facilement assuré en vue d'obtenir une robustesse et une fiabilité particulièrement notable.The construction of the device of the invention can therefore call on simple organs whose assembly can be easily assured in order to obtain robustness and particularly notable reliability.

Le support 11 est par exemple constitué par le sol 11.The support 11 is for example constituted by the ground 11.

De manière remarquable, le dispositif est conçu de manière réversible, c'est à dire, de manière telle que le matériau liquide transféré du réceptacle premier dans le réceptacle second (figure 2) puisse être, le cas échéant, transféré du réceptacle second dans le réceptacle premier (figure 3) et ainsi de suite le cas échéant.Remarkably, the device is designed so reversible, i.e., such that the material liquid transferred from the primary receptacle to the receptacle second (Figure 2) can be transferred from the second receptacle in the first receptacle (Figure 3) and so on if necessary.

A cet effet, le dispositif comprend un plan PS de symétrie sécant à la surface d'exposition 8 et de part et d'autre duquel les réceptacles premier 3 et second 6 se trouvent disposés.To this end, the device comprises a plane PS of symmetry intersecting on the exposure surface 8 and on either side of which the receptacles first 3 and second 6 are arranged.

De préférence et de manière remarquable, le plan PS de symétrie contient l'axe 7D de basculement.Preferably and remarkably, the PS plan of symmetry contains the tilt axis 7D.

Ces caractéristiques permettent que, cependant que l'atmosphère située au dessus des réceptacles 3, 6 est contrôlée, le dispositif autorise plusieurs transferts du matériau liquide du réceptacle premier vers le réceptacle second, puis vice-versa de manière à parfaire le traitement dudit matériau liquide.These features allow that, however the atmosphere above receptacles 3, 6 is controlled, the device authorizes several transfers of the liquid material from the primary receptacle to the receptacle second, then vice versa in order to perfect the treatment of said liquid material.

Le moyen 7A de basculement comprend :

  • un moyen 7E de guidage de la structure, autour d'au moins un axe 7D sensiblement parallèle au bord 3C de déversement du réceptacle premier 3 et ce, entre les positions première P1 et seconde S1,
  • un moyen 7F moteur pour le basculement de la structure autour de l'axe 7D de basculement,
  • un moyen 7G de commande du moyen 7F moteur.
The tilting means 7A includes:
  • a means 7E for guiding the structure, around at least one axis 7D substantially parallel to the edge 3C of discharge of the first receptacle 3 and this, between the positions P1 first and S1 second,
  • a motor means 7F for tilting the structure around the tilting axis 7D,
  • a means 7G for controlling the motor means 7F.

Le moyen 7E de guidage et le moyen 7F moteur sont avantageusement constitués par une crémaillère courbe qui, supportant la structure 10 du dispositif, est quant à elle placée en appui sur des roues dentées qui sont guidées en rotation par rapport à un support 11, tel le sol, et dont au moins l'une est mue par un organe moteur 7F d'entraínement en rotation.The guide means 7E and the motor means 7F are advantageously constituted by a curved rack which, supporting the structure 10 of the device, is itself resting on toothed wheels which are guided in rotation relative to a support 11, such as the ground, and of which at least one is driven by a drive member 7F for driving in rotation.
