Description
Die gründliche und schnelle Erwärmung von Flüssigkeiten mit Hilfe des elektrischen
Stromes ist bereits in verschiedenen Ausführungsarten bekannt. Auch induzierter Wechselstrom
gab gute Ergebnisse. Man verfuhr hierbei derart, daß man die metallische, um
einen Jochschenkel führende Heizschlange, durch welche die Flüssigkeit hindurchströmt,
den sekundären Stromkreis bilden ließ,
ίο Bei der vorliegenden Erfindung liegt ein wesentlicher Unterschied insofern vor, als die
. zu erhitzende Flüssigkeit unmittelbar selbst den sekundären Stromkreis bildet. Durch
geeignete Zusätze läßt sich die Leitfähigkeit der Flüssigkeit wesentlich erhöhen, so daß
deren elektrischer Widerstand ziemlich herabgemindert werden kann.The thorough and rapid heating of liquids with the help of electric current is already known in various forms. Induced alternating current also gave good results. The procedure here was that the metallic heating coil leading around a yoke leg, through which the liquid flows, was allowed to form the secondary circuit,
ίο In the present invention, there is a significant difference in that there is. liquid to be heated directly forms the secondary circuit itself. The conductivity of the liquid can be increased significantly by suitable additives, so that its electrical resistance can be reduced considerably.
Die Heizschlange selbst wird aus nichtleitendem Stoff hergestellt. Eine solche Einrichtung hat vor der bekannten den Vorzug, daß, da die Wärme in der Flüssigkeit selbst erzeugt wird, die Wärmeverluste geringer sind.The heating coil itself is made of non-conductive material. Such a facility has the advantage over the known one that, since the heat is generated in the liquid itself, the heat losses are lower are.
Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Um den Schenkel a1 eines Transformatorjoches α ist die primäre Wicklung in Form . einer Spule b gelegt. Um denselben Jochschenkel oder um den dazu parallelen Schenkel α2 ist in einer gut isolierenden Heizschlange c die zu beheizende Flüssigkeit als sekundärer Stromkreis geführt. Tritt die Flüssigkeit bei d in diese Heizschlange ein, so steht sie unter der induzierenden Wirkung des magnetischen Feldes! im Joche, sobald der Primärstrom durch die Spule b fließt, und tritt bei e in heißem Zustand wieder aus.An exemplary embodiment of the subject matter of the invention is shown in the drawing. The primary winding is in the form around the leg a 1 of a transformer yoke α. a coil b placed. Around the same yoke leg or around the leg α 2 parallel to it, the liquid to be heated is routed as a secondary circuit in a well-insulating heating coil c. If the liquid enters this heating coil at d , it is under the inducing effect of the magnetic field! in the yokes as soon as the primary current flows through the coil b , and emerges again at e when it is hot.
Diese Anordnung gestattet eine kontinuierliche Erhitzung von Flüssigkeiten und weiter eine zirkulative Beheizung, wenn die beiden Heizschlangenenden d und e miteinander verbunden sind.This arrangement allows continuous heating of liquids and further circulative heating when the two heating coil ends d and e are connected to one another.
Durch Ab- und Zuschaltung von Windungen der Primärspule b durch sog. Zapfstellen läßt sich die in den Ofen gesandte Energie genau regulieren, wie sich auch der Ablauf bei e durch einen Durchgangshahn bequem drosseln bzw. regeln läßt.By disconnecting and connecting turns of the primary coil b through so-called tapping points, the energy sent into the furnace can be precisely regulated, just as the process at e can be conveniently throttled or regulated by a through valve.
