Definitions

  • the invention relates to a method and a device for readjusting the pole spacing in electrolysis cells, in particular for aluminum melt flow electrolysis, consisting of movable anode bars, to which individual anode blocks are attached in an electrically conductive manner via anode rods.
  • the anode bar has large differences in position in the upper and lower positions. This makes the current path and the power loss large. There are also considerable fluctuations in the magnetic field and other procedural disadvantages.
  • the lowering of the anodes required to eliminate the anode effect leads to an increase in the bath level, which can result in the anode carbons being flooded and possibly even in the melt escaping.
  • the object of the present invention is to avoid the disadvantages mentioned in the known method for readjusting the pole spacing and eliminating the anode effect and to enable the individual anodes to be precisely adapted to the respective anode erosion.
  • the rise in the bath level when eliminating the anode effect can be avoided. This is done by simultaneously lowering and lifting off a part of the anodes in such a way that the additionally displaced volume of the bath melt is compensated for by the volume of the anode carbons drawn out.
  • anode rod Due to the slight lifting or lowering movement of the anode bars, it is possible for the first time to use a largely rigid riser to the neighboring furnace when connecting the anode / cathode and to dispense with an auxiliary cross beam, which previously led to considerable work in the operation of the individual electrolysis cells. Furthermore, the anode rod can be kept much shorter compared to the previous technology, which leads to considerable material and weight savings.
  • Figures 1 and 2 show a schematic representation of the electrolytic cell in cross section.
  • the anode bars 1, 2 are connected to the anode carbons 4 via the anode rods 3.
  • the whole is held in a supporting structure 5, on which a spindle gear 6 for driving the spindle 7 is also arranged.
  • the spindle 7 has an opposite slope in the upper and lower half.
  • Fig. 1 u. 2 shows an electrolytic cell in partial cross section.
  • the furnace pan 8 the refractory base insulation 9 and the carbon base (cathode) 10 can be seen.
  • the edge infeed (carbon) 11 and the cathodic steel rail 12 can be seen in the lateral area.
  • the liquid metal is designated 13 and the electrolysis bath 14.
  • FIG. 1 the position of the anode bar 1 is shown shortly before reaching the lower end position.
  • the anode rod 3 In order to allow a further lowering of the spent anode carbon 4, the anode rod 3 must now be switched from the lower anode bar 1 to the upper anode bar 2.
  • the spindle gear 6 is first stopped. Then the anode rod 3 is connected to the upper anode bar 2 via the lock 15. Then the lock 16 on the lower anode bar 1 is released.
  • the anode carbon 4 to be lifted is clamped to the upper anode bar 2 via lock 18 when the spindle gear 6 is at a standstill. While all other anode carbons remain attached to the lower anode bar 1.
  • the pole spacing of the anode carbon to be set increases, since the upper and lower anode bars 1, 2 move in opposite directions.
  • the upper anode bar is separated again from the anode rod 3 via the lock 18, which is then connected to the lower anode bar 1 via lock 17.
  • anode burnup is approx. 1.5 to 2 cm per day, a stroke of the anode bar of less than / equal to 5 cm is sufficient to carry out all conceivable lifting and lowering movements.
  • the anode rods can therefore be made very short and the distance of the scaffold from the electrolysis bath can also be kept very small, which leads to a reduction in the overall height of the electrolysis cell.
  • the lifting-lowering movement of the anode bars 1, 2 is initiated via a spindle 7 with an opposite slope.
  • appropriately designed spindle nuts must be arranged in the anode bars 1, 2.
  • each anode bar 1, 2 can be controlled with a separate drive via an electric motor or a hydraulic cylinder.
