Description
Es ist in der Technik zur Erhitzung von Materialien, zum Kochen usw., sehr oft erforderlich, Heizbäder zu verwenden. In diesen Heizbädern werden Flüssigkeiten benutzt, welche eine .entsprechend hohe Erhitzung gestatten. It is very often required in technology for heating materials, for cooking, etc. Use heating baths. Liquids are used in these heating baths, which allow a correspondingly high level of heating.
Die elektrische Erhitzung dieser Bäder ist besonders zweckmäßig und einfach mit blanken Widerstandskörpern durchzuführen. Allerlo.· dings besieht die Schwierigkeit darin, daß sie leicht auswechselbar, vor Kurzschlüssen, geschützt, mehrfach abstufbar auch bei Drehstrom sein müssen. Es hat sich gezeigt, daß es möglich ist, in folgender Weise eine solche Heizung durchzuführen.The electrical heating of these baths is particularly useful and easy with bare Perform resistance bodies. However, the difficulty is that they Easily exchangeable, protected against short circuits, multiple graduations even with three-phase current must be. It has been shown that it is possible to do so in the following manner Perform heating.
Auf einer Platte von Eisenblech werden zwei oder mehr Isolatoren mit einer entsprechenden Anzahl von Riefelungen angebracht, i Der Widsrstandsdraht wird der Reihe nach um diese Isolatoren gewickelt. An den Enden des Drahtes wird der. Strom zugeführt.On a plate of sheet iron are two or more insulators with a corresponding one Number of corrugations attached, i The resistance wire is sequentially wrapped around these insulators. At the ends of the wire, the. Electricity supplied.
Es besteht eine Gefahr darin, daß die Drähte, wenn die Isolatoren sehr weit voneinander entfernt sind und die Riefelungen sehr eng, die Drähte sich infolge Ausdehnung bei der Wärme stellenweise berühren können und Kurzschlüsse entstehen. Es hat sich gezeigt, daß dieser Nachteil dadurch zu vermeiden ist, daß man die Isolatoren etwas schräg stellt. Dieses kann etwa dadurch geschehen, daß die ganze Platte, auf welcher sich die Isolatoren befinden, schräg angebracht ist.There is a danger that the wires will break if the insulators are very far apart are removed and the corrugations are very tight, the wires expand as a result can touch the heat in places and short circuits occur. It has shown, that this disadvantage can be avoided by placing the isolators at a slight angle. This can be done, for example, by removing the entire plate on which the insulators is located at an angle.
Als besonders zweckmäßig hat sich eine Anordnung der Isolatoren ergeben, welche in der Zeichnung dargestellt ist. Die Eisenplatte ist hier in Form eines T. Der DrahtAn arrangement of the insulators has been found to be particularly useful, which is shown in the drawing. The iron plate is here in the shape of a T. The wire
wird mit dem einen Ende um die unterste Riefelung des Isolators 2 geschlungen, von dort aus um die unterste Riefelung von 1, dann S, dann 3, dann 4,. dann die nächst höhere Riefelung von 1 usf. Das Ende des Drahtes wird wiederum um eine Riefelung- der Rolle 2 geschlungen. Am Anfang und Ende des Drahtes, die auf diese Weise voneinander isoliert sind, wird je ein Kontakt c für die Stromzuführung angebracht. Man kann auch, z- B. bei Drehstrom oder auch für die Erhitzung in mehreren Stufen, mehrere solcher Schaltungen an diesem. System anbringen. Dieser Körper eignet sich auch, um zu mehreren zusammengesetzt zu werden, wenn größere Energiemengen nötig sind. Zweckmäßig wird dann aus den einzelnen T-Sektoren ein Kreis zusammengesetzt. Dies kommt besonders auch in Betracht bei der Erhitzung, mit Mehrphasenstrom. is looped with one end around the lowest corrugation of the insulator 2, from there around the lowest corrugation of 1, then S, then 3, then 4 ,. then the next higher corrugation of 1 and so on. The end of the wire is again looped around a corrugation of roll 2. At the beginning and the end of the wire, which are insulated from one another in this way, a contact c is attached for the power supply. You can also, for example with three-phase current or for heating in several stages, several such circuits on this. Attach system. This body is also suitable to be put together in several if larger amounts of energy are required. A circle is then expediently put together from the individual T-sectors. This is particularly important when heating with multiphase electricity.
