Description

  

  Schraubverbindung an Elektroden von     Elektrolyseuren.       Die Verbindung der Elektroden bei Bi  polar-Elektrolyseuren wird durch Schrauben,  Nieten oder Schweissen bewerkstelligt. Wäh  rend die beiden letztgenannten Verfahren eine       Iialtreckung    des Materials! verursachen, was  eine erhöhte Gefahr der 'Wasserstoffbrüchig  keit bedeutet, ist dies bei der Verschraubung  nur dann der Fall, wenn die Schraubverbin  dungen über die Fliessgrenze hinaus bean  sprucht werden. Die Erfahrung lehrt,     dass     jedoch diese Gefahr bei     Schraubverbindungen     meistens besteht, da mit Rücksicht auf eine  gute elektrische Verbindung die Schrauben  fest angezogen werden müssen.  



  Erfindungsgemäss wird der     obengenannte     Nachteil dieser     Schraubverbindung    dadurch  vermieden, dass eine durchgehende Schraube  mit verjüngtem Schaft verwendet wird, der  als elastisches Glied wirkt. Damit ist eine  sichere,     dauernde        Anpressung    der Elek  troden ohne Überbeanspruchung des Mate  rials möglich.         Fig.    1 der beiliegenden, schematischen  Zeichnung zeigt im     Schnitt    eine übliche Aus  führung einer Schraubverbindung, wobei 1  die Anode, 2 die     Trennwand,    $ die Kathode,  4 die     Diaphragmen    und 5 eine Schraub  verbindung bedeutet.

   Letztere besteht aus  zwei beidseitig in eine Hülse 6 eingeschraub  ten Schrauben 7.  



       Fig.    2 zeigt ein Ausführungsbeispiel der  Erfindung mit der durchgehenden Schraube  B. Der verjüngte Schaft 9, welcher die  höchste Beanspruchung     aufweist,    ist durch  die Hülse 6 vom Elektrolyt abgeschirmt, um  die Gefahr der     Wasserstoffbrüchigkeit    zu       vermeiden.  



  Screw connection on electrodes of electrolysers. The connection of the electrodes in bi-polar electrolysers is accomplished by screwing, riveting or welding. During the last two processes mentioned, the material is stretched! cause, which means an increased risk of hydrogen brittleness, this is only the case with the screw connection if the screw connections are stressed beyond the flow limit. Experience shows that this danger usually exists with screw connections, since the screws must be tightened firmly in order to ensure a good electrical connection.



  According to the invention, the above-mentioned disadvantage of this screw connection is avoided in that a continuous screw with a tapered shaft is used, which acts as an elastic member. This means that the electrodes can be reliably and permanently pressed on without overstressing the material. Fig. 1 of the accompanying schematic drawing shows in section a conventional execution of a screw connection, where 1 the anode, 2 the partition, $ the cathode, 4 the diaphragms and 5 means a screw connection.

   The latter consists of two screws 7 screwed into a sleeve 6 on both sides.



       2 shows an embodiment of the invention with the through screw B. The tapered shaft 9, which is subject to the highest stress, is shielded from the electrolyte by the sleeve 6 in order to avoid the risk of hydrogen brittleness.
