Definitions
- 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.
- 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.
- 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.
- 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.
- 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.
- tools often called "electrolysis service machines” or “M.S.E” (“PTA” or “Pot Tending Assembly “or” PTM “or” Pot Tending Machine "in English).
- 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.
- 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.
- 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.
- FIG. 1 illustrates a typical electrolysis room, seen in section, intended for the production of aluminum and including a service unit represented so schematic.
- Figure 2 illustrates, schematically and in side view, a service module an aluminum production plant by igneous electrolysis according to the invention.
- FIG. 3 illustrates a connection device according to the invention, seen in section.

- the electrolysis cells (2) are normally arranged in rows or lines (typically side-by-side or head-to-head), each row or line comprising typically more than a hundred cells.
- Said cells (2) include a series of anodes (21) provided with a metal rod (22) intended for fixing and electrical connection of the anodes to a metallic anode frame (not shown).
- the service unit (3) is used to carry out operations on the cells (2) such as changing the anode or filling the feed hoppers with ground bath 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 service unit (3) comprises a movable bridge (4) which can be translated above electrolysis cells (2), and along them, and a service module (5) comprising a mobile carriage (6) capable of being moved on the mobile bridge (4) and several handling and intervention devices (7, 8, 9, 10, 11), such as tools (shovels, keys, biters, ...) and control booths.
- the movable bridge (4) rests and circulates on raceways (30, 30 ') arranged parallel to each other and to the main axis of the hall (and of the cell line). The movable bridge (4) can thus be moved along the electrolysis room (1).
- the hub (102) is locked in rotation relative to the fixed frame (101).
- the fixed chassis (101) is typically above the rotary chassis (110, 120).
- the axis of rotation (103) is normally substantially vertical.
- the first rotary frame (110) rotates with the sleeve (121) and drives it in rotation typically by mechanical means (123) such as a finger.
- Said pluralities of rotary sliding electrical contacts (113, 114) comprise typically rings or tracks attached to the sleeve (121) and brushes or wipers fixed to the chassis (101, 120).

- Distribution conductors (118, 1181, 1182, 119) are conductors of the connection device which are likely to be driven by the rotation of the rotating frames (110, 120).
- Distribution conductors include a first series of conductors (118, 1181, 1182) which are normally fixed by relative to the sleeve (121) and to the first rotary frame (110), and a second series conductors (119) which are normally fixed relative to the second chassis rotary (120).
- the annular bearings (111, 112) are typically rolling bearings, such as roller crowns.
- connection device (100) advantageously comprises one or more assembly means for holding said frames (101, 110, 120) in a determined axial position.
- assembly means can be in whole or in part integrated into the annular bearings (111, 112).
- the drive systems (140, 141, 142, 150, 151, 152) include typically a motor (140, 150), a pinion (141, 151) and a ring gear (142) or a gear (152).
- the motor (140, 150) and the crown (142, 152) can be fixed respectively to the fixed frame (101) and to one of the rotating frames (110, 120), or vice versa.
- the motor (140, 150) can be fixed to the rotating chassis or fixed by mechanical means such as an arm (153).
- the drive systems may include one or more drive rollers by grip and at least one track.
- the connecting device (100) advantageously comprises annular bearings complementary (160, 161, 162, 163, 164) between the sleeve (121) and the fixed frame (101), possibly via the hub (102) - as illustrated in Figure 3 - And / or complementary annular bearings (170, 171) between the sleeve (121) and the second rotating frame (120). These additional bearings make it possible to avoid lateral displacements of the rotary elements (110, 120, 121).
- connection device comprises also rotary pneumatic and / or hydraulic connection means (130, 131, 132, 133) between the fixed chassis (101) and at least one of the rotary chassis (110, 120), and preferably both, and therefore for at least one of the turrets.
- These means of connection allow in particular a supply of compressed air to the organs of handling and intervention.
- These means advantageously include a cavity axial (130) in the central unit shaft (102), watertight rotary joints (131, 132) and additional pipes (133, 134).
- the first rotating frame (110) is located between the fixed frame (101) and the second rotating frame (120).
- the drive system of the second rotary frame (120) preferably comprises a toothed wheel (152) fixed to the hub (102) and a motor (150) fixed to the second rotary chassis (120) and provided with a pinion (151).
- the first turret (110 ') typically includes a control (11) and a hopper (10) containing the anode covering product.
- the second turret (120 ′) typically includes the various service tools for electrolytic cells, such as a stitching device (8) intended to break the crust alumina and cryolite which forms around and between the anodes, a shovel (7) intended for the removal of solid elements contained in an electrolysis cell at the time of an anode change and an anode handling system (9) intended for the extraction of spent anodes and for the installation of new anodes.
- the connecting device (100) is then typically placed so that the rotating frames (110, 120) are located below the fixed frame (101) when the carriage (6) is in the position of use on the overhead crane (4).
- the service module according to the invention allows the operator to have a large visibility on the electrolysis cell and on the tools or handling devices and intervention during his interventions. It also simplifies the task of the operator, in particular by avoiding significant angular rotations by compared to its original point. It also makes it possible to use the same module in separate electrolysis rooms in which the electrolysis cells are not oriented in the same way.
- the invention also relates to a service unit (3) of a production plant of aluminum by igneous electrolysis comprising an overhead crane (4) and at least one service module (5) according to the invention.
