Definitions

  • the present invention relates to a device for assaying carbonaceous paste obtained from a mixture of liquid pitch and crushed coke intended to feed mold forming machines for producing electrodes, in particular anodes, for the electrolysis of aluminum.
  • the electrolysis of aluminum by the Hall-Héroult process requires the prior manufacture of carbon anodes.
  • the anodes are made from, in particular, liquid pitch and crushed coke, mixed and kneaded to obtain a relatively homogeneous paste.
  • the paste obtained must then be accurately metered and then molded into blocks in compaction machines by vibrocompaction. The precision of the dosage allows for a more regular height of the blocks.
  • the molded blocks are then introduced into ovens known as rotating lights, where they are fired in order to obtain the electrolysis anodes.
  • Compaction machines are known by vibrocompaction, also called forming machines, vibrocompaction machines or vibrocompaction machines, essentially comprising a mold of parallelepipedal shape of rectangular cross-section removably mounted on a vibrating table constituting the bottom of the mold and a mass pressing, able to be introduced axially into said mold by an upper end of the mold.
  • the vibrating table is secured to a frame by means of suspension means and is subjected to vibration in a substantially vertical direction, along the axis of the mold, under the effect of vibration actuating means.
  • the device consists of a table, called shaking or vibrating, mounted on springs and on which is fixed a mold.
  • a table called shaking or vibrating
  • Under the shaking table are at least two rotary unbalanced parts which are mounted and rotated so that the horizontal components of the oscillations, they generate in the table, cancel each other out.
  • the rotation of unbalanced parts causes a substantially harmonic and vertical oscillation of the shaking table, the granules introduced into the mold thus being compressed by vibration in the form of a compact block.
  • a mold 1 of parallelepipedal general shape of rectangular cross section of substantially vertical axis, vertically displaceable, and removably mounted on a vibrating table 2, and a pressing mass 3.
  • the pasty mixture is compacted under the effect of the hammering of the pressing mass 3.
  • the unbalanced shafts 5 rotate. opposite direction and induce an excitation in the table 2 which then takes a vertical sinusoidal movement.
  • the table 2 is installed on an elastic suspension 6 to limit vibration transmissions to the ground 7 and / or in the vicinity of the machine 1 '.
  • the lower end of the pressing mass 3, called the impression 8 penetrates inside the mold 1 to give the shape of the top of the molded block. Under the effect of the vertical movements that the table 2 communicates with the dough 4, the pressing mass 3 bounces on top of the block being formed.
  • a known feeder 10 is shown on the figure 3 . It consists essentially of a storage hopper 11 , fixed with respect to the compaction machines, which is responsible for collecting the carbonaceous paste produced by the upstream process, said storage hopper 11 serving as a buffer between the upstream stream of pulp generally continuous and the batch flow of dough necessary for feeding the compaction machines.
  • a vibrating extractor 13 located under the storage hopper 11 withdraws the carbonaceous paste to transport it and pour it into a weighing hopper 14 .
  • This extractor 13 may be electromagnetic or unbalanced type or any other type of drive.
  • a flap 12 is located at the outlet of said storage hopper 11 and makes it possible to have a paste layer of uniform height in the vibrator 13.
  • This vibrating extractor 13 is provided with a control system making it possible to vary the speed of extraction in an important report. Typically this speed can vary from 15% to 100% and more precisely from 60 to 100% at the beginning of the dosing cycle and from 15 to 30% at the end of the dosing cycle for a more precise dosage.
  • the storage hopper 11 and the vibrating extractor 13 are suspended on load cells to know the exact mass of the dough they contain.
  • the weighing hopper 14 is also suspended on weighers to know the exact mass of the dough it contains.
  • a motorized distribution flap 15, driven by an alternating tilting movement, is installed in the flow of dough between the discharge orifice of the vibratory extractor 13 and the inlet orifice of the weighing hopper 14, thus enabling to dispense the paste evenly over the entire length of the weighing hopper 14.
  • the weighing hopper 14 is equipped at its base with an opening and closing system comprising two half-helmets 18 with synchronized tilt, said half-helmets 18 being actuated by one or more cylinders 19.
  • the opening of the half-helmets helmets 18 of the weighing hopper 14 causes a drop of the carbonaceous paste in a transfer hopper 21 of a transport device 20 .
  • the synchronized half-helmets 18 are closed again with the aid of the hydraulic jack or cylinders 19, the weighing hopper 14 is ready for a new weighing cycle.
  • the transfer device 20 is moved by means of a rolling carriage 22 along rails 23 to a first compaction machine has for example and, when the hopper 21 of transfer arrived at the appropriate position, the carbonaceous paste contained in the transfer hopper 21 is poured into the mold 1 of the machine using a similar opening and closing device to that of the weighing hopper 14.
  • the transport device 20 is moved again, so that the transfer hopper 21 returns to position itself under the weighing hopper 14 while waiting for a new loading to feed the machine 1'b of following compaction.
  • this system makes it possible to operate several compaction machines simultaneously from a single carbon paste feed point.
  • the dosing cycle time between the storage hopper 11 and the transfer hopper 21 can not be reduced significantly without significantly increasing the inaccuracy on the mass of pulp dosed in the weighing hopper 14 and therefore on the molded block height.
  • this is not compatible with the subsequent use of the oven molded blocks. Indeed a block height accuracy of +/- 10mm is usually required to ensure their placement in these furnaces, and more precisely +/- 5mm.
  • the production rate of the blocks is therefore limited, in particular by the uncertainty on the dosage of the dough in the hopper 14 weighing. Indeed, the duration of the dosing cycle, in particular because of the filling and dosing steps, must be sufficient to obtain the correct accuracy on the determination of the carbonaceous paste.
  • the control device thus allows, thanks to its at least three positions, to obtain several flow rates of dough, to adjust the accuracy of the assay, while not increasing the dosing cycle time.
  • the object of the invention is in particular to overcome the limitations of the previously described pulp metering device by proposing a device capable of more rapidly dosing the quantity of carbonaceous paste in the weighing hopper while maintaining the same precision or even increasing the accuracy dosing doser more precisely.

  • the vibrating extractor 103 comprises in particular a bottom 106 on which the carbonaceous paste flows.
  • the bottom 106 may be slightly inclined downwardly relative to the horizontal, between the storage hopper 101 and the hopper 104 weighing so as to promote the flow of the carbonaceous paste under the effect of gravity.
  • the vibratory extractor 103 is in the form of an upwardly open, substantially flat bottom channel 106, comprising two side walls 105 rising from the bottom 106 so as to form a U-shaped section.
