Definitions

  • ABSTRACT Apparatus for automatic and controlled positioning of anodes in electrolytic cells for producing ferrous metals and the like.
  • the apparatus comprises a bridge crane for supporting and lifting an anode and a transducer responsive to the bridge crane movement and supplying pulses to a bidirectional counter, said pulses being representative of the anode lifting from the operating position in the electrolytic bath to a reference plane.
  • a reference mark relative to a sight must be provided on the anode shank, so as to determine the distance to the bottom face of the anode to be replaced.
  • the anode is then removed from the bath by a lifting means, such as a bridge crane, thus providing for hooking the new anode to be placed in position.
  • a metrical rod or caliper a reference mark has to be provided on this new anode, so that the distance between this mark and the bottom face of the carbon anode will correspond to the distance as measured on the replaced anode. This would involve labour and manual operations responsible of slowing down the replacement times.
  • the operator attached to such an operation has to operate under unpleasant conditions due to occasional high temperature of the anode to be replaced.
  • the repositioning of the new anode may be not quite accurate, as a result of errors in observation by the operator.
  • an apparatus for automatic and controlled positioning of anodes in electrolytic cells for producing ferrous and nonferrous metals associated with an anode lifting and moving means, such as a bridge crane, characterized by comprising a device sensitive to the movement which, by responding to the movement of the lifting means moving along with the anode, will supply to a counting means a series of pulses that, in a convenient measurement unit, will represent the anode lifting from its position in the bath to a reference plane.
  • Another feature of the apparatus according to the present invention is the possibility of providing an automatically operating means, as a pull is exerted on the anode by the bridge crane, to energize said counting means counting the pulses supplied by said device responsive to the movement.
  • FIG. I is a schematic view showing the apparatus according to the invention, as associated with a bridge crane and when removing an anode from an electrolytic cell;
  • FIG. 2 shows the anode as removed from the electrolytic cell and placed on a reference plane
  • FIG. 3 shows a new anode which is also placed on the reference table and is then to be placed in the electrolytic bath.
  • the apparatus according to the invention for indicating the difference in height between the lower limit of the electrode and the abutting plane 8 substantially comprises a transducer 5 responsive, for example, to the linear movement of the crane structure, or to the drum rotation, or to the movement of the rope or cable and the like, and capable of supplying electrical pulses to a counter 6, preferably a bidirectional type of electronic digital counter, counting the pulses being received by said transducer 5.
  • the invention also provides a second transducer 7 responsive to the weight of the anode on structure 4, at the pull beginning this transducer 7 supplying a starting pulse to counter 6.
  • the bridge crane provides for lifting the anode 2 from bath ll.
  • said weight sensitive transducer 7 supplies a counting start pulse to counter 6.
  • transducer 5 responsive, for example, to the drum rotation or to the linear movement of the crane structure, supplies the counter 6 with pulses representing said movement on the base of a predetermined measurement unit.
  • the counter 6 will count these pulses until the replaced anode is placed on the reference plane 8.
  • the transducer 7 will supply a stop pulse to counter 6, and therefore the number of pulses as indicated by said counter 6 will correspond to the difference in height L.
  • An apparatus for automatically controlling the positioning of anodes in electrolytic cells for producing ferrous and nonferrous metals, associated with anode lifting and moving means, comprising:
  • a first transducer responsive to the exertion of weight by said anode on said lifting means as said lifting means begins to lift said anode, for producing a count start pulse to said counter
  • a second transducer responsive to movement of said body member, for producing a series of pulses to said counter representative of the net movement of said anode lifting means in a predetermined direction; from an operating electrolytic bath position to a position on a reference plane;
  • said first transducer adapted to be responsive to the releasing of exertion of weight by said anode on said lifting means as said lifting means positions said anode on said reference plane for producing a count stop pulse to said counter.
