Definitions
- the present invention relates generally to the change from spent anodes to within aluminum production electrolysis tanks. It concerns everything particularly a module capable of allowing the actual extraction of worn anodes and the installation using such modules.
- Aluminum is produced industrially by the well-known process today of igneous electrolysis, that is to say using the electrolysis of alumina in a molten cryolite bath according to the reaction:
- This highly exothermic reaction therefore sets up a molten bath comprising a mixture of cryolite and alumina, the temperature of which is generally higher than 800 ° C, and consumes a lot of electricity, so that the installations operate in continuous mode, in order to limit the energy losses inherent in the phases restart.
- the invention therefore consists, firstly, in differentiating two movements, in know a movement requiring intense effort on a short run at reduced speed, and a movement requiring significantly less effort on a much longer run long, also at a much higher speed.
- this module is particularly suitable for uprooting and transfer worn anodes.
- the second organ is intended to allow the implementation of a intense tensile force, necessary and sufficient to allow the actual lifting of the spent anode outside the electrolysis bath, while the first organ, after removal effective of said anode, ensures the displacement thereof outside the tank.
- the first member consists of a cable lifting system, carrying one or more cables wound on one or more several drums driven by an electric motor, and fitted with a hauling system level of which is fixed a tool, for example for gripping the anode, for breaking the upper crust of the electrolysis bath or of a tool acting as a shovel recovery of pieces from said layer.
- said second member consists of a mechanical or electro-mechanical jack, at the end of which are fixed the cable or cables of said first member.
- the invention consists in making a system for lifting a load provided with a fixed point, said fixed point being capable of being made mobile over a race limited by means of said second member, that is to say in the present case, of a jack mechanical or electro-mechanical.
- the module is provided with a cable slack, so as to limit the load applied by the tool, with which said module is provided, on an obstacle, and in particular in bottom of electrolytic cell.
- this slack in the cable makes it possible to maintain the turns of cables perfectly wound at the level of the drum (s), and is also designed not to not apply any effort to the level of the installation plan, as specified in a more detailed manner detailed later.
- the tool holder module comprises a mast semi-rigid vertical guide, secured to the chassis of said module, and along which slides a tool carriage itself.
- the invention also relates to the installation for changing spent anodes of aluminum production electrolysis tanks.
- This installation includes an overhead crane capable of moving above said tanks and on which moves in a direction perpendicular to the translation of the bridge a cart fitted with a tool holder module for extracting and transferring spent anodes out of the tanks, and to convey to the said tanks new anodes.
- the maximum value of the angle between two extreme tool holders is ideally smaller than the size of the control cabin, located above of said vertical tree. In the absence of such a cabin, the angle separating two or two tools extreme tool holder is less than 180 °.
- this installation can be implemented within existing installations, by minimizing interference and the risks of interaction with, in particular, gas evacuation pipes, in particular fluorinated and carbon monoxide and dioxide, from each of the tanks.
- FIG. 1 is a schematic representation in partial section of an installation according to the invention.
- FIG. 2 is a representation similar to FIG. 1, but in a view perpendicular to the view of FIG. 1.
- FIGS. 3a, 3b and 3c are diagrammatic representations in plan of the different phases of movement of the tool-holder modules, in particular during a change in activation of the tool.
- Figure 4 is a schematic representation relating to the principle of implementation of the tool holder modules according to the invention, of which Figure 5 is a representation of an example of a wiring system, and Figure 6 is a top view in Figure 5.
- Figures 7, 8 and 9 are respectively schematic perspective representations of the tool holder module according to the invention, respectively alone and associated with two modules of the same nature, according to two different views.
- Figures 10 and 11 are schematic representations of the operation of the slack cable used at said module according to the invention.
- FIG. 1 a partial sectional view of the installation according to the invention. Basically, it consists of an overhead crane (1), likely to move in translation on a raceway (5) above a electrolysis cell (2), and more precisely from a series of substantially identical cells to each other within which a molten electrolysis bath is maintained, containing in a known manner cryolite and alumina.
- the temperature of the bath is greater than 800 ° C., said bath being subjected to a voltage of about 4.5 volts, the intensity of the direct electric current flowing inside of it typically being of the order of 180,000 to 200,000 amperes.
- this traveling crane (1) receives a carriage (6) capable of moving over a raceway (7) perpendicular to the translation of the crane.
- This cart (6) receives a platform (8), surmounting a vertical central shaft (9), at the level of which is mounted a succession of coaxial crowns one above the other, respectively (10), (11) and (12).
- Each of these crowns has an extension, located substantially in the same plan, and at the level of which is fixed one or more modules (13, 14, 15) of the type described below.
- the maximum angle between the two extreme tools is less than 120 °.
- these angles can be defined according to the characteristics existing facilities, without causing any modification thereof.
- Each of the crowns is equipped with a means of controlling the angle of rotation of the tool or the tool holder that it carries, the angle being determined from a fixed point on the support shaft of said crowns.
- an encoder mounted on the motor shaft of the gear motor for driving the crown in question indicates the angle of rotation of the tool holder from a signal given by a fixed limit switch in rotation.
- an anti-collision system, proximity sensor type, mounted on each tool is associated with the fixed limit switch in rotation, ensuring the relative angular control of the tools.
- the platform (8) receives an upper cabin (not shown), intended to receive the user, the latter being likely to actuate the tools there considered and the corresponding tool holders while monitoring the operation.
- the shaft (9) can also receive a number of coaxial rings additional, likely to carry other tools than those mentioned previously, and in particular a tool for opening the covers (3) of the tanks (2) by example, brushes, etc ...
- the pricking tool is folded towards the left in the direction of the lifting tool, and the tool carrying the shovel is rotated by 270 °, until reaching the level of the tank considered (figure 3b).
- the carriage (6) is first moved on the crane in order to spread the shaft (9), and starting from the tool-holder modules of the piping (4), then the rotation of the tool considered is carried out by taking care before reassembling the tool carriage (25) at its maximum travel on the stiffening mast (23), described below in more detail., When the rotation of said tool is complete, the carriage (6) is returned to its position original.
- each of the tool holder modules and in particular the anode changing modules, have two activation systems independent. They firstly comprise a system of cables (13), wound on one or more two drums (14), the latter being driven in rotation by means of an electric motor (15), via a wheel reducer (16) and worm (17), each wheel (16) being integral and coaxial with one of the drums (14) and coming to cooperate with the screw (17) collinear with the motor shaft of the motor (15). These drums are positioned at level of the upper chassis of each module.
- the cable or cables (13) are wound on two pulleys constituting a hauling system (18) and go up towards a fixed point (19).
- the load and in particular the tool holder considered, is fixed at the level of hauling by any suitable means, itself being secured to a carriage (25), as described in more detail detail below.
- the fixed point (19) is itself secured to the end of the screw (20) a mechanical jack (21), driven by an electric motor (22).
- this double lifting system makes it possible to implement a conventional lifting ensuring the displacement travel of the anodes over relatively large distances at a relatively high speed for a reduced load, and lifting with lifting, likely to develop a significant effort on a reduced race with speed limited.
- This device allows by its traction capacity, on the one hand to develop the effort necessary to tear off the used anode, intended to be replaced, but moreover, given the corresponding low speed, it makes it easier to set up the new anode at the level of the tank.
- the organs of the kinematic chain, and in particular the wheels (16), the drums (14) and the cables (13) are dimensioned as a function of the intense force exerted by said second organ, and to which they are subject, taking into account their solicitation during the phase tear.
- each of the tool holder modules is provided with two drums (14) synchronized by design of the reducer, and each receiving two cables (13), so that the total number of cables is four, as shown in particular in the figures 10 and 11, for example.
- the total number of cables is four, as shown in particular in the figures 10 and 11, for example.
- the tool holder modules are associated change of anodes by three, as shown in Figures 8 and 9.
- This configuration is intended to allow the simultaneous change of three spent anodes. he it is of course nevertheless that each of the modules is likely to function independently of each other, so that, notwithstanding the implementation of a system with three modules, only one or two of them can be activated for the change of anodes.
- the distance between the three tool-holder modules corresponds to the distance between the anodes. This spacing is likely to be different depending on the installation concerned and is therefore adjustable. It is determined by rods, the length of which corresponds to said center distance. This arrangement allows the system to be adapted to any type of installation.
- each tool holder module is associated a vertical guide mast (23), secured to the level of the upper chassis of the module by through a pre-stress device incorporating ball joints, thus susceptible to allow a certain degree of freedom at the level of the lower part (24) of the mast.
- This mast (23) is intended to allow guiding, in particular of a carriage (25) containing the hauling (18) and by extension of the load suspension zone, this carriage (25) being provided with rollers (26) bearing on either side of said mast (23).
- This mast is semi-rigid.
- the threshold for adjusting the pre-stress is such that we are notably freed from risks of angular movement of said tool holder, in particular at the end of travel, in the event of limited efforts, and in particular those inherent in the intense magnetic field that prevails in the installation, and to which the metallic elements constituting a most of the elements used in the construction of the module
- each module comprises a system of slack, thus limiting the vertical travel of the tool when it comes to interact with an obstacle, such as when the shovel comes into contact the bottom of the tank.
- an obstacle such as when the shovel comes into contact the bottom of the tank.
- the slack in the cable allows keep the turns of cables perfectly organized on the drums (14).
- This slack cable is more particularly described in connection with Figures 10 and 11.
- Sa implementation is obtained by securing in a non-fixed manner, the hauling (18) to the carriage (25) for moving the tool holder on the mast (23) by means of a set of two connecting rods (27, 28), capable of moving according to a deformable parallelogram, and articulated respectively on the frame (29) at which the haulage is mounted, and on said carriage (25), between two extreme positions, corresponding to the take-up stroke slack in the cable represented by the double arrow A in FIG. 10.
- FIG. 10 represents the carriage (25) bearing on an object or an obstacle surrounding, the frame (29) no longer being in contact with said carriage (25).
- a sensor no shown, positioned between the carriage (25) and the frame (29) will have given the order to stop the lifting motor while it was making a downward movement.
- the stopping distance maximum mobile hauling is represented by the double arrow A.
- Figure 11 shows the carriage (25) suspended without contact with the environment, the frame (29) which carries the hauling pulleys being in contact with the carriage (25).
- a spring can be put in place between the upper face of the frame (29) and the carriage (25), in order to reduce the apparent weight of said carriage on an object surrounding, allowing in this hypothesis, to preserve the electrolysis tank and its environment.
- the tool holder module according to the invention is dimensioned to accept efforts to the neighboring load of 10 tonnes for speeds of the order of one millimeter per second. On the other hand, for speeds of the order of 15 meters per minute and longer runs significant, the displacement effort is of the order of 2 tonnes.

Description
On a décrit dans le document US-A-5 816 565 un système de levage mettant en oeuvre deux organes de levage interagissant entre eux.
En revanche, quelle que soit la qualité de l'huile mise en oeuvre au niveau de ces vérins hydrauliques, compte tenu de la température élevée du bain de fusion, le risque d'incendie est permanent et, on souhaite s'affranchir de cet inconvénient rédhibitoire.
Les solutions proposées jusqu'alors pour éviter l'utilisation du système d'extraction hydraulique se heurtent à un problème d'encombrement et au génie civil des installations existantes. En effet, ces solutions, mettant typiquement en oeuvre un système à câble, demandent un encombrement largement supérieur, incompatible avec ces installations ou, nécessitant la réalisation de nouvelles installations, grevant de manière trop significative les coûts correspondants avant d'être susceptibles d'être amorties.
L'objet de l'invention est donc de proposer une installation pour le changement d'anodes usées au sein d'une série de cuves d'électrolyse, s'affranchissant de ces inconvénients, et notamment compatible avec les usines existantes et s'affranchissant des risques inhérents à la mise en oeuvre de dispositifs hydrauliques. Elle concerne en premier lieu un module porte-outil, destiné notamment à recevoir un outil pour permettre l'arrachage et le transfert des anodes usées. Ce porte-outil peut également intégrer tout type d'outil, et notamment un dispositif apte à rompre la croûte supérieure qui se forme à la surface du bain, mais également d'une pelle ou similaire, destinée à collecter les morceaux de croûte issus de cette rupture.
Ce module porte-outil, destiné à être mis en oeuvre au sein d'une installation de levage, est caractérisé en ce qu'il est muni de deux organes de levage motorisés de manière indépendante :
- un premier organe, constitué d'un système de levage comprenant au moins un câble, un ou deux tambours motorisés électriquement, un mouflage au niveau duquel est fixé un porte-outil, ledit ou lesdits câbles venant s'enrouler sur ledit ou lesdits tambours(s), et étant renvoyé(s) au niveau du mouflage, ledit premier organe de levage étant destiné à assurer le déplacement d'une charge au niveau du mouflage à vitesse relativement importante et selon une course étendue ;
- un second organe, dont l'un des éléments constitutifs est solidarisé à l'extrémité du ou des câbles dudit premier organe après renvoi au niveau du mouflage et comprenant des moyens permettant d'assurer en coopération avec ledit mouflage le déplacement vertical à vitesse réduite et selon une course limitée d'une charge plus importante.
- à permettre de rompre la croûte superficielle qui se créée à la surface supérieure du bain d'électrolyse de chacune des cuves ;
- à collecter tout ou partie des morceaux provenant de la rupture de ladite croûte ;
- et à extraire et transférer les anodes usées hors des cuves et acheminer au niveau desdites cuves des anodes neuves,
La figure 1 est une représentation schématique en section partielle d'une installation conforme à l'invention.
La figure 2 est une représentation analogue à la figure 1, mais selon une vue perpendiculaire par rapport à la vue de la figure 1.
La figure 4 est une représentation schématique relative au principe de mise en oeuvre des modules porte-outils conformes à l'invention, dont la figure 5 est une représentation d'un exemple de système de câblage, et la figure 6 est une vue du dessus de la figure 5.
Les figures 7, 8 et 9 sont respectivement des représentations schématiques en perspective du module porte-outils conforme à l'invention, respectivement seul et associé avec deux modules de même nature, selon deux vues différentes.
Les figures 10 et 11 sont des représentations schématiques du fonctionnement du mou de câble mis en oeuvre au niveau dudit module conforme à l'invention.
