Definitions
- the present invention relates to a preheating connector for the electrical connection of an anode rod to an anode frame of a preheating electrolysis cell, an electrolysis cell equipped with this preheating connector, and a method electrically connecting the anode rods to the anode frame of an electrolytic cell to preheat the electrolytic cell.
- An electrolysis cell traditionally comprises a metal box with a refractory lining.
- a cathode of carbonaceous material is disposed at the bottom of the box.
- the cathode In continuous operating mode, during which aluminum is produced, the cathode is covered with a sheet of liquid aluminum and an electrolytic bath, and anodes of carbonaceous material are partially immersed in the electrolytic bath. Each anode is attached to one end of an anode rod.
- the anode rods are connected to an anode frame by means of electrical and mechanical connection systems also called connectors.
- these connectors for the electrical and mechanical connection of the anode rods to the anode frame during the continuous operating regime of the tank will be designated as permanent connectors.
- the anode frame is secured to a superstructure supported by concrete feet resting on the box and serving as electrical insulation between the box and the superstructure.
- the anode frame is movable relative to the superstructure to allow adjustment of the position of the anodes, which are consumed in the electrolytic bath as the electrolysis reaction.
- the continuous operating mode of an electrolytic cell is preceded by a preheating phase of the tank, intended to bring the tank from an initially cold state to an operating temperature of about 960 ° C.
- This preheating phase allows, by a gradual rise in temperature, to avoid thermal shocks at the cathode that could reduce the service life of the tank.
- the electrolysis cell in phase preheating does not contain a liquid electrolytic bath and the anodes are not suspended from the superstructure but rest on the layer of carbonaceous material.
- preheating connectors electrical connection systems from anode rod to the anode frame, hereinafter referred to as preheating connectors, ensuring good electrical contact between the anode rod and the anodic frame and allowing displacements of the anode rod relative to the anode frame to take into account its expansion.
- the existing preheating connectors must be removed as soon as the preheating is complete to allow the installation of permanent connectors adapted to the continuous operating condition of the tank.
- the risk of degradation of the quality of the contact between the anode rod and the anode frame is not perfectly ensured.
- the present invention aims to overcome all or part of these disadvantages by providing a preheating connector easily manipulated and easy to maintain, limiting the risk of degradation of the quality of the contact between anode rod and anode frame including transition period between the preheating phase and the start of the continuous operating regime of the electrolysis cell.

- the preheating connector according to the invention offers the possibility of being place and used while a permament connector is already present, ie to coexist with a permanent connector. It is therefore possible, thanks to the preheating connector according to the invention, to prepare the continuous operating mode of the tank (once preheating is complete) by actuating the permanent connectors without removing the preheating connectors beforehand. This results in the maintenance of a quality electrical contact during the transition period between the end of the preheating phase and the start of continuous operation of the tank.
- the hooking means and the support means are shaped and arranged to superpose the preheating connector to the permanent connector.
- the hooking means comprise a hook.
- the support means comprise two levers hinged about an axis and means for connecting and clamping the levers, each lever supporting at least one bearing surface for come to bear against the anode rod.
- the preheating connector according to the invention offers the advantage of a simple structure to maintain and handle.
- each bearing surface corresponds to a wall of a rotary roller.
- This feature has the advantage of allowing a translation movement of the anode rod relative to the anode frame to compensate for the expansion of the components of the tank, while allowing to keep the plated anode rod against the anode frame.
- this rotary roller is designed in an electrically insulating material, resistant to heat and having a low coefficient of friction.
- the levers each comprise two cheeks spaced from each other by a predetermined distance by at least one crosspiece.
- the cheeks of a lever delimit a space for receiving the permanent connector.
- the one or one of the cross supports the one or one of the bearing surfaces.
- the connecting means and clamping levers comprise two jaws each intended to be assembled to one of the levers and a threaded rod connecting the two jaws.
- the jaws each comprise two grooves and the levers each comprise two end hooks, the end hooks and the grooves of the jaws co-operating in a complementary manner for assembling the jaws with the levers.

- the method may comprise a step of placing the permanent connectors 12 (one for each anode rod 2), when they are not already there. This step is illustrated in FIG. 3. More precisely, this step may comprise the positioning of each end of the axis 18 of each permanent connector 12 in a hook 20 fixed to the anodic frame 6. The permanent connectors 12 are thus suspended from the anodic frame 6.
- the method comprises a step of positioning a first lever 8, illustrated in Figure 4.

- This step consists of placing a jaw 30 on the first lever 8, a jaw 30 on the second lever 8, then to insert a threaded rod 32 connecting the two jaws 30 if it is not already the case. It is then sufficient for an operator to ensure that the first lever 8 and the second lever 8 are articulated around the axis 18 to which they have been hooked, then to screw the threaded rod 32 to bring the jaws 30 closer together, therefore the rotation of the levers 8 about the axis 18 and the support of the rotary rollers 24 against the anode rod 2 via the electrically insulating strip 26.
- the permanent connectors 12 are loosened: they do not contribute to the electrical connection of the anode rods 2 to the anode frame 6 supporting them. At most, the permanent connectors 12 play a role in supporting the preheating connectors 1 when they are hooked to the axis of the permanent connectors 12.
- the permanent connectors 12 are tightened in order to electrically and mechanically connect the anode rods 2 and the anodic frame 6 (the anode rods 2 are immobilized and become integral with the anodic frame 6. supporting).
- the preheating connectors 1 are then loosened (by inverse rotation of the threaded rod 32).
- the quality of the electrical contact is maintained during the transition between the preheating phase and the continuous operating regime.
- this transition is fast since it does not require removing the preheating connectors 1 and then put in place 12 permanent connectors.
- the preheating connectors 1 can be removed (without specific tools given their geometry and mass), or left in position, loosened.
- the axis 18 of articulation of the preheating connectors 1 does not necessarily correspond to an axis of a permanent connector 12 but may correspond to a separate axis attached to the electrolytic tank 4.
- the jaws 30 can also be an integral part of each lever 8, the ends of the jaws being integral with one or other of the flanges 14 of each lever 8.
