Description
Die Erfindung bezieht sich auf eine elektrische Heizvorrichtung, die aus mehreren räumlich hintereinander an einer Haltevorrichtung angeordneten und elektrisch hintereinandergeschalteten Ringheizkörpern mit Temperaturregler und Schmelzsicherung besteht und die zur Erwärmung von Flüssigkeiten, insbesondere von Öl, in-geschlossenen und nur durch eine kleine Öffnung zugängliehen Gefäßen dient.The invention relates to an electrical Heating device consisting of several spatially one behind the other on a holding device arranged and electrically connected in series Ring heating elements with temperature controller and fuse and which are used to heat liquids, especially of oil, in-closed and only accessible through a small opening Serving vessels.
Es sind Heizvorrichtungen bekannt, die durch enge Spundlöcher in das Innere von geschlossenen Behältern, etwa Fässern, hineingesteckt werden können. Dabei sind in einer gemeinsamen Rohrummantelung mehrere vollzylindrische keramische Heizpatrone!) räumlich hintereinander angeordnet und elektrisch in Reihe geschaltet. Nach außen hin wirkt ein solches Gerät jedoch nur als ein.There are heating devices known through narrow bung holes in the interior of closed containers, such as barrels, can be inserted. In a common pipe sheathing several fully cylindrical ceramic heating cartridges!) spatially arranged one behind the other and electrically connected in series. Outwardly however, such a device only acts as a.
einziger Stabheizkörper und kann nur stehend in Betrieb gesetzt werden, wodurch wegen seiner Länge .stets ein hoher Flüssigkeitsstand bedingt ist. Außerdem ist an diesen Geräten kein Temperaturregler und kein Übertemperaturschutz, der eine Verwendung in explosionsge'fährdeten Räumen zuließe, vorhanden. only rod heater and can only be put into operation standing, which is because of its length. always a high liquid level is required. Also on these devices no temperature controller and no overtemperature protection, which would allow use in areas at risk of explosion.
Diese Nachteile vermeidet die Erfindung; sie besteht darin, daß außer den an dem einen Schenkel der winkelförmigen Tragvorrichtung sitzenden Heizkörpern am anderen Schenkel der Tragvorrichtung ein Hilfsheizkörper zur Beeinflussung der Temperaturüberwachungseinrichtung angeordnet ist, der hinsichtlich seiner Heizleistung je Flächeneinheit ebenso oder annähernd ebenso wie die anderen Heizkörper bemessen ist.The invention avoids these disadvantages; it consists in the fact that besides those on that one leg of the angular support seated radiators on the other Leg of the support device an auxiliary heater for influencing the temperature monitoring device is arranged, which in terms of its heating power per unit area as or approximately as the other radiator is sized.
Der oder die Zuleitungsstiele zu den einzelnen Heizkörpern, das Rohr zur Aufnahme des Temperaturreglers und das Rohr für die auswechselbare Schinelzsicherung münden zweckmäßig in einen gemeinsamen Gerätekopf.The one or more supply line stems to the individual radiators, the pipe for receiving of the temperature controller and the tube for the exchangeable Schinelzfuse open expediently in a common device head.
Durch die erfindungsgemäße Ausbildung der Heizvorrichtung können auch kleine Flüssigkeitsmengen, etwa von Öl in Fässern und in den Tanks von Flugzeugen, aufgeheizt werden, ohne daß bei ^mangelnder Beaufsichtigung eine Überhitzung des Öles und damit eine chemische Zersetzung unter Qualmentwicklung eintritt, obwohl wegen der verhältnismäßig hohen Heizleistung die Erwärmung einer kleinen Restmenge sehr schnell erfolgt. In den Räumen, in denen Ölfässer aufbewahrt werden, Hegen auch meistens Benzinbehälter, und so besteht die Möglichkeit, daß "sich explosible Gasgemische bilden. Da aber das Gerät mit einer Temperaturüberwachungseinrichtung, oder auch zusätzlich mit einer Schmelzsicherung versehen ist, kann es auch ohne umgebende Flüssigkeit eingeschaltet werden, weil die Oberfläche der Heizkörper keine solchen Temperaturen erreicht, die zur Zündung des Gasgemisches ausreichen.The inventive design of the heating device can also small Quantities of liquid, such as oil in barrels and in the tanks of aircraft, are heated up without overheating of the oil and thus chemical decomposition with the development of smoke occurs, although because of the proportionate high heating output, a small amount of residual heat is heated very quickly he follows. In the rooms where oil barrels are kept, they are mostly cherished Gasoline containers, and so there is the possibility that "explosive gas mixtures are formed. But since the device is equipped with a temperature monitoring device, or in addition is provided with a fuse, it can also be switched on without any surrounding liquid because the surface of the radiator does not reach temperatures that ignite the gas mixture sufficient.
