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.
- the most modern factories are equipped with one or more service units comprising a movable bridge that can be translated over the electrolysis cells, and along the series of cells, and one or more a plurality of service machines each comprising a trolley and a service module provided with handling and intervention devices (often called “tools”), such as shovels and hoists, and able to be moved on the movable bridge.
- tools handling and intervention devices
- 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 substantially increases the risk of damage to tools during maintenance operations.
- the European patent application EP0618313 describes a compact service module mounted on a telescopic arm moving in the vertical direction.
- the subject of the invention is a service module that can be used in an igneous electrolysis aluminum production plant and comprises a chassis that can be fixed to a carriage and a turret mounted on the chassis so as to be able to pivot about an axis.
- vertical A in use and equipped with a plurality of handling and intervention devices, and characterized in that it comprises a set of tools, in that each tool of said assembly is mounted on a telescopic arm attached to the turret by an articulated support that allows pendular movements of the telescopic arm relative to a specific point of articulation while prohibiting the rotational movement of the telescopic arm about a reference axis, called "main axis", associated with this telescopic arm, and in that the telescopic arms of the determined set of tools are interconnected by a mechanical connection device capable of maintaining in a given tolerance range the relative angular difference between the pendular movements of the telescopic arms.
- the Applicant has had the idea of allowing pendulum movements without rotation of the support means of certain tools, in order to give these tools a freedom of positioning which does not change their basic orientation, and to synchronize these pendular movements while at the same time conferring a limited independence of movement (thanks to said determined tolerance domain), which makes it possible to prevent them from colliding without rigidly linking them to one another. Said flexibility makes it possible in particular to prevent the jolts suffered by one of the tools from directly affecting the other tools in the set.
- the service module according to the invention can thus be both compact and flexible, which makes it possible to make tight approaches with tools protected against significant accidental efforts. Indeed, the invention avoids the disadvantages of rigid attachment to the turret, which makes high risk of damage by false maneuver.
- the set of tools typically comprises at least one tool selected from crustal shovels, anode handling tongs and stingers.
- the invention also relates to a service machine comprising a carriage and a service module as described above.
- the invention also relates to a service unit of an igneous electrolysis aluminum production plant comprising a mobile bridge and at least one service machine according to the invention.

- the cells (2) comprise a series of anodes (21) provided with a metal rod (22) for fixing and electrically connecting the anodes to a metal anode frame (not shown).
- the service unit (3) is used to carry out operations on the cells (2) such as anode changes or the filling of ground feed hoppers and AlF 3 of the electrolysis cells. It can also be used to handle various loads, such as tank elements, pockets of liquid metal or anodes.
- the invention particularly relates to the service units that can be used to effect the anode changes.
- the service unit (3) comprises a movable bridge (4) which can be translated over and along the electrolysis cells (2), and a service machine (5) comprising a trolley mobile (6) movable on the movable bridge (4) and a service module (7) equipped with several handling and intervention devices (10), such as tools (shovels, keys, stitches, .. .).
- the movable bridge (4) rests and circulates on raceways (30, 30 ') arranged parallel to each other and to the main axis of the room (and the queue of cells). The movable bridge (4) can thus be moved along the electrolysis room (1).
