Description
Elektrode für elektrisch geheizte @ Dampfkessel. Um bei elektrisch geheizten Dampfkesseln mit eingebauten Elektroden :den Weg des elektrischen Stromes innerhalb des Kesselwassers einigermaßen festzulegen, ist es bekannt, den Übergang des Stromes ausschließlich auf die Elektroden zu beschränken, indem man insbesondere die Stromzuführungsleiter zu den Elektroden gegen das Kesselwasser isoliert. Zu diesem Zweck hat man bisher Röhren aus Glas, Quarz oder anderem keramischen Stoff über den Stromzuführungsdraht geschoben, welche vom Einführungsisolator bis zur Elektrode reichten. Derartige Isolierröhren haben aber den Nachteil, daß sie unnachgiebig sind und daher leicht brechen, und daß ferner an bestimmten Stellen, vor allem an der Stelle der Wasseroberfläche, Korrosionen auftreten, wodurch die ganze Röhre öfters erneuert werden muß.Electrode for electrically heated @ steam boilers. To with electric heated steam boilers with built-in electrodes: the path of electric current It is known to set the transition within the boiler water to some extent to limit the current exclusively to the electrodes, in particular the power supply conductors to the electrodes are insulated from the boiler water. to tubes made of glass, quartz or other ceramic material have hitherto been used for this purpose pushed over the power supply wire, which extends from the lead-in insulator to the Electrode was enough. Such insulating tubes have the disadvantage that they are intransigent are and therefore break easily, and that also in certain places, especially at the body of the water surface, corrosion occurs, causing the whole tube often has to be renewed.
NTach der Erfindung wird die Isolierung der Elektrodenzuleitung durch aneinandergereihte kurze Rohrstücke bewirkt, (die in mehreren Lagen derart konzentrisch übereinander gestülpt werden, daß durch .die äußere Lage die Stoßstellen der inneren Lage überdeckt werden.According to the invention, the insulation of the electrode lead is through short pieces of pipe lined up in a row (which are so concentric in several layers be put on top of each other that .the outer layer, the joints of the inner Layer to be covered.
In der Zeichnung ist ein Ausführungsbeispiel für die Erfindung dargestellt. Der Elektrode a wird Strom 'durch die Metallstange b zugeführt, die bei e in die Metallklappe d eingeschraubt ist. Diese ist mit der Klemme e versehen und bedeckt die äußere Öffnung des Einführungsisolators f, gegen den sie mittels der Stopfbüchse g gedichtet ist. Die Kappe d selbst ist mittels isolierter Stehbolzen h an :der Kessel-,vand h befestigt, ,die ihrerseits mittels der Stopfbüchse i gegen den Einführungsisolator f gedichtet ist. Auf die Zuführungsstange b sind erfindungsgemäß zwei konzentrische Lagen von kurzen Isolierröhren in, ii geschoben, derart, daß ihre Stoßstellen sich überdecken. Die oberste Isolierröhre ragt in das Innere des Isolators f hinein.In the drawing, an embodiment of the invention is shown. The electrode a is supplied with current 'through the metal rod b , which is screwed into the metal flap d at e. This is provided with the terminal e and covers the outer opening of the lead-in insulator f, against which it is sealed by means of the stuffing box g. The cap d itself is attached to the boiler wall h by means of insulated stud bolts h , which in turn is sealed against the inlet insulator f by means of the stuffing box i. According to the invention, two concentric layers of short insulating tubes in, ii are pushed onto the feed rod b in such a way that their joints overlap. The uppermost insulating tube protrudes into the interior of the insulator f.
Wenn zwei Lagen derartiger Röhren nicht genügen, können drei oder mehr Lagen verwendet werden.If two layers of such tubes are not enough, three or more layers can be used.
