Definitions

  • ABSTRACT The anode of an electrolytic cell is connected to a bus bar Foreign Aiiplication Priority Data Apr. 16, 1969 through a connection device in which a lead wire connected at one end to the bus bar is connected at the other end to the anode through a solder joint, on which a continuous separating force is exerted by a springseparating mechanism.
  • a connection device in which a lead wire connected at one end to the bus bar is connected at the other end to the anode through a solder joint, on which a continuous separating force is exerted by a springseparating mechanism.
  • This invention relates generally to electrochemical processes and apparatuses and more particularly to a new protective connection device for connecting an electrode in an electrolytic cell to a power-supply conductor and operating promptly, when a short circuit occurs in the electrolytic circuit, to break the connection and thereby to protect various parts of the electrolytic apparatus.
  • a protective connection device in which a lead-wire conductor is connected to a conductor from an electrode by means of a joining metal of low melting point, and a separating mechanism is provided to exert on the two conductors a continual force urging them apart, whereby, when an excessive current due to a short circuit flows through the conductors, the joining metal melts and the conductors are separated to break the electrolytic circuit.
  • FIG. 1 is an elevation partly in section and with parts 'cut away, showing one example of an anode conneCtion device according to the invention in connected state;
  • FIG. 2 is a similar view showing the same device in disconnected or circuit-breaking state.
  • the anode connection device illustrated therein in normal connective state connects a bus bar 8 to an anode bar 1 connected at its lower end to an anode (not shown).
  • the upper end of the anode bar I is tapped and is connected to the threaded lower end 5 of a coupling plate 2 screwed thereinto.
  • the upper end of the coupling plate 2 is in the form of a cup-shaped socket 3, the inner surface of which is conneCted by solder 7 to one end of a flexible lead strap 6 made up of several laminated layers of copper sheets 4.
  • the other end of this lead strap 6 is connected by a bolt 9 to the bus bar 8.
  • the coupling plate 2 and lead strap 6 are respectively fixed by bolts 11 and 12 to coaxially opposed lower and upper heads 13 and 14 of a spring-powered separating mechanism 10.
  • This separating mechanism 10 is in the form of an extensible strut and comprises the coaxial lower and upper heads 13 and 14, a guide rod 16 fixed at its upper part to the lower part of the upper head 14 by a screw connection 17, an electrically insulating gland or bush 18 made of a material such as polyvinyl chloride and having a central bore slidably engaged with the lower end of the guide rod [6 when theconnection device is in the connected state shown in FIG.
  • the insulating bush 18 serves to insulate the upper head I4 and parts connected thereto from the lower head 13 and parts connected thereto thereby to prevent electric current from flowing through the separating mechanism 10 irrespective of the state of the connection device.
  • connection device of the invention is of simple organization and operation affording low cost of manufacture and maintenance. Furthermore, after this device has operated in response to a short circuit, it can be readily restored to its original state without any damage whatsoever after the cause of the short circuit has been removed.
  • a protective connection device for the wiring of an electrode bar in an electrolytic cell which comprises; an electrode bar; a vessel-shaped socket connected to said electrode bar through a coupling means; a flexible lead-wire conductor connected at one end thereof to the inner surface of said socket by means of a metal of low melting point; and a separating means comprising a first head having an insulating bush secured interiorly thereof and secured to said coupling means,
  • a second head secured to said lead-wire conductor, a guide rod fixed at one end thereof to said second head and adapted to engage slidably with a guide bore in said bush, and a spring positioned between said first and second heads and maintained in a deflected state for exerting a force for urging said first and second heads apart, said force tending to cause separation of said end of the conductor and the socket, whereby, when an excessive electric current flows through said conductor, and melts said low melting metal, said force causes such separation, said separating mechanism being provided with at least one insulating member to prevent flow of electric current between the lead-wire conductor and the socket thus separated.
