Description
Vorrichtung zum isolierten und dampfdichten Hindurchführen elektrischer Leitungsdrähte durch die Wandung eines Dampfkessels. Bei dem bekannten, sogenannten Cumberlandverfahren, nach welchem elektrischer Strom z. B. in Dampfkessel oder in unter Vakuum stehende Kessel geleitet wird, zum Zweck,- die in dem Kesselwasser befindlichen Kesselsteinbildner niederzuschlagen, bietet die Einführung der Stromzuleitungen in das Innere des Kessels große .Schwierigkeiten, da die Elektrodeneinführungen nicht nur elektrisch isoliert, sondern auch gegen DampfdruckoderVakuumabgedichtetwerden müssen.Device for the insulated and vapor-tight passage of electrical Conductor wires through the wall of a steam boiler. In the known, so-called Cumberland method, according to which electric current z. B. in steam boiler or in under vacuum boiler is passed, for the purpose of - those in the boiler water to knock down existing scale builders, offers the introduction of the power supply lines Big difficulties into the inside of the boiler because of the electrode insertions not only electrically isolated, but also sealed against vapor pressure or vacuum have to.
Bei den bisherigen 'Ausführungen dieser Art, war es üblich, die dampfdichte Abdichtung durch Stopfbüchsen zu erreichen. Da die Einführungselektrode jedoch gleichzeitig durch elektrisch isolierende, meist nachgiebige und sich bei der hohen Dampftemperatur leicht verändernde Mittel umgeben ist, ist es schwer, die Dampfdichtigkeit und Isolation zu erzielen.In previous designs of this type, it was customary to use the vapor-tight Achieve sealing by means of stuffing boxes. However, as the lead-in electrode at the same time by electrically insulating, mostly flexible, and at high steam temperatures Is surrounded by easily changing means, it is difficult to maintain the vapor tightness and insulation to achieve.
Diese Erfindung vermeidet die Nachteile, indem sie die geeignet isolierte Elektrode an dem Kessel durch-Flansch abdichtet, wodurch gegenüber der Verwendung von Stopfbüchsen selbst beim Zwischenliegen von Isoliermaterial durch entsprechendes Anziehen der Verbindungsschrauben ein absolut dampfdichter Abschluß zu erzielen ist.This invention avoids the disadvantages by isolating those appropriately Electrode to the boiler through-flange seals, thus preventing use of stuffing boxes even with the interposition of insulating material by appropriate Tighten the connecting screws to achieve an absolutely vapor-tight seal is.
In der Zeichnung ist als Beispiel eine solche Abdichtung im Querschnitt dargestellt. Die Einführungselektrode e ist beispielsweise durch Asbest, Zement. oder eine sonst geeignete Isoliermasse m in einem Rohr r in geeigneter Weise dem; Dämpfdruck . widerstehend eingebettet.In the drawing, such a seal is shown in cross section as an example. The lead-in electrode e is made of, for example, asbestos, cement. or another suitable insulating compound m in a pipe r in a suitable manner ; Damping pressure. Resistently embedded.
An dem Rohr r ist ein Flansch f befestigt, der auf eine an der Kesselwandung w angeordnete Platte p durch Schrauben s gepreßt wird. Die Verbindung zwischen Rohr r und Flansch f mit der Platte p des Kesselmantels m stellt also die dampfdichte Einführung der Elektrode dar, während die elektrische Isolierung der Elektrode e durch die in geeigneter Weise gegen Herausdrücken gesicherte Isoliermasse m erreicht ist.A flange f is attached to the pipe r and is pressed onto a plate p arranged on the boiler wall w by means of screws s. The connection between pipe r and flange f with the plate p of the boiler shell m thus represents the vapor-tight introduction of the electrode, while the electrical insulation of the electrode e is achieved by the insulating compound m, which is suitably secured against being pushed out.
Selbstverständlich ist es nicht erforderlich, die Platte p direkt auf der Kesselwand w @zu befestigen, da dies insbesondere bei bereits im Betrieb befindlichen Kesseln umständlich ist, sondern es kann diese Platte durch ein kurzes Rohrstück mit der Kesselwandung als Kesselstutzen verbunden werden.Of course, it is not necessary to direct the plate p to be attached to the boiler wall w @, as this is particularly important when the boiler is already in operation located boilers is cumbersome, but it can be this plate by a short Pipe section can be connected to the boiler wall as a boiler nozzle.
