Definitions
- the invention relates to the field of aluminum production by igneous electrolysis, in particular according to the HALL-HEROULT method, and more particularly the management of certain stages of the operation of the facilities for such production.
- It relates more particularly to a lifting device of the anode frame, it is to say of the organ carrying the different anodes within the same tank.
- These anodes in this case consist of carbon sealed on a conductive metal rod of electricity.
- the bottom of the tanks supports a cathode.
- the tanks generally comprise two horizontal conductive bars, generally called anode frames, supported by at least one rigid horizontal metal beam, adjustable in height.
- the carbon anodes are generally positioned along two parallel lines, and are supported by conductive rods releasably connected to each of the two anodic frames.
- the anode frame on which are fixed the anodes via the rods metal regularly decreases at the rate of carbon consumption constituent of the anode, by the chemical reaction of electrolysis, by means of of a mechanism implanted on the tank.
- the purpose of the descent of the anodes within the cryolite and alumina bath is keeping the air gap between the anode surface and the cathode substantially constant.
- this operation of raising of the anode frame must be carried out without interrupt the continuous process, including without cutting off the electrical current.
- the anodes mounted on the frame must be maintained at the height they had reached during the lifting operation of the framework, without ceasing to be in close and intimate contact with the said framework, in order to do not interrupt the continuity of the electric current.
- the invention proposes a solution to this problem, both simple to implement and effective in his action.
- the gripping and holding members are arranged on each side and other of the tank, and therefore on both sides of the portico.
- the pendulum movement of the modules pressure is ensured by means of an activator, and in particular a pneumatic cylinder, in the absence of the activation of which a return spring induces the plating of said pressure modules against the gantry, ie canceling any pendulum movement, and as a result, a plating of the anode rods against the anode frame.
- the gripping module is constituted a clamp located at the lower end of the gripping and holding member, said clamp being open under the action of an activator, and in particular a jack pneumatic in the absence of whose activation, a spring induces its closure on said anode rod.
- the gripping module is capable of to be the object of pendular movements, but this time in the plane of the stems anode on the same side of the tank.
- FIG. 1 shows an igneous electrolysis cell (21), within which from which plunge a series of anodes (24). These anodes are electrically connected to anode frame (23), via a conductive rod (12), substantially vertical, further ensuring the function of maintaining the anodes.
- the anode frame (23) is capable of translating vertically with respect to a frame (22) extending above the tank. During this translation, by means of a lifting beam of the anode frame (not shown) the anode frame causes the anodes (24) which are secured to it.
- FIG. 2 shows the device according to the invention.
- a gantry (1) substantially symmetrical, and intended to be positioned above each of the electrolysis tanks.
- This gantry is for example, moved from one tank to another, by means of one or two lift trucks, which are provided with the upper decks in the aluminum production facilities.
- This gantry (1) has at its two ends zones (2) and (3) articulation a plurality of gripping and holding members (5) of the anode rods.
- gripping members (5) there are as many gripping members (5) as there are anodes and as can be seen in FIG. 2, these gripping members are distributed on both sides other of the tank.
- This gantry (1) intended to rest on the tank, is electrically isolated from grippers (5) by means of intermediate elements (11) made in one insulating material, typically polytetrafluoroethylene (Teflon - registered trademark).
- the gripping members (5) first of all comprise a presser module, capable of being animated by a partial rotation movement relative to the hinge axis (4), according to a plane perpendicular to the plane containing the anode rods on the same side of the tank.
- the presser module is maintained vertical via a calibrated spring (7), respectively taking bearing against the outer wall (6) of the zones respectively (2) and (3), and against the piece link (8), joining the articulation axis (4) of the gripping member (5) well said.
- the spacing of said module from its vertical position is ensured by means of a pneumatic cylinder of the type flexible cylinder slab (9), taking bearing against the internal partition (10) of the zones respectively (2) and (3) and against connecting piece (8), as can be seen in Figure 2.
- the gripping module of the anode rods (12) consists of a gripper (13), whose the two parts are articulated in (14), so as to allow the approximation of gripping areas (15) of the clamp from each other, and thus to ensure the function of tightening and gripping the rods (12).
- a spring (16) with vertical action, integrated in the body (17) of the gripping member (5) ensures the approximation of the elements of gripping (15) from one another, and thus holds the clamp (13) in the clamping position.
- the particular architecture of the device according to the invention, and in particular the position of the actuators above the anode rods (12) allows to release the four lateral faces of the organ (5), thus freeing the mechanism of the constraints right or left of each of the actuators, these constraints being imposed by positive climb (electrical current) arrivals at the level of anodic frame. It allows corollary to implement two functions complementary of improvement of the electrical contact anode rod - anode frame, the operation is done just before loosening the connectors, and just after the tightening the connectors, assuring as already said, fixing the rods on the frame anodic.
- the lifting beam according to the invention also has a certain modularity, thus likely to make it adaptable to different morphologies of tank.
- the gripping and holding members (5) are adjustable in terms of fixation on the gantry (1) constituting the lifting beam.
- the gripping modules are also likely to represent a pendulum movement in the plane of the rods anodic.
- the pendular system (18) is free of any constraint, on the other hand the system (20) is adjustable by means of springs and screw, so as to allow a lateral deflection of the order of 20 to 30 mm. This allows a greater tolerance of adaptation of the gripping modules at the level of anode rods.
