Description

Verbindung des Ablaufstutzens eines in einem Außenkessel angebrachten, durch Dampf, Glyzerin, Wasser o. dgl. als Wärmeträger erhitzten Innenkessels mit der Wand des Außenkessels Gegenstand der Erfindung ist die Befestigung des Ablaufrohres für einen in einem Außenkessel angeordneten inneren Kochkessel.Connection of the drainage nozzle of an installed in an external boiler, inner boiler heated by steam, glycerine, water or the like as a heat transfer medium the wall of the outer boiler The subject of the invention is the attachment of the drain pipe for an inner cooking kettle arranged in an outer kettle.

Bei den bisher hergestellten Kochvorrichtungen, bei denen der eigentliche Kochkessel durch Dampf, Glyzerin, Wasser o. dgl. als Wärmeträger erhitzt wird, treten beim Erwärmen am Auslaufstutzen durch die starre Verbindung des Außen- und des Innenkessels erhebliche Spannungen auf, die hervorgerufen werden z. durch die unterschiedlichen Wärmeausdehnungswerte der für den Innen- und Außenkessel verwendeten Werkstoffe (z. B. Gußeisen als Werkstoff für den Außenkessel und Nickel, Aluminium, nichtrostender Stahl oder Kupfer für den Innenkessel) und 2. dadurch, daß der mit kaltem Kochgut gefüllte Innenkessel sich wesentlich langsamer erwärmt als der nichtgekühlte Außenkessel.In the previously manufactured cooking devices, where the actual Boiling kettle is heated by steam, glycerine, water or the like as a heat transfer medium when heating at the outlet connection due to the rigid connection of the outer and inner kettle considerable stresses that are caused e.g. through the different Thermal expansion values of the materials used for the inner and outer boiler (e.g. cast iron as a material for the outer boiler and nickel, aluminum, more rustproof Steel or copper for the inner kettle) and 2. in that the with cold food filled inner kettle heats up much more slowly than the non-cooled outer kettle.

Durch die ständige Aufeinanderfolge der Verschiedenheit in der Ausdehnung und Zusammenziehung der beiden Kessel werden Spannungen hervorgerufen, die zu Undichtigkeiten führen, nicht nur an den Verbindungsstellen der Stutzen mit den Innenkesseln, sondern es wird sogar die Naht des Innenkessels mitunter rissig.Because of the constant succession of differences in expansion and contraction of the two boilers creates tensions that lead to leaks not only at the connection points between the nozzles and the inner boilers, but sometimes even the seam of the inner cup becomes cracked.

Nach der Erfindung wird dieser Übelstand dadurch vermieden, daß das Ablaufrohr durch eine Membran aus Metall oder aus einem anderen elastischen Werkstoff mit dem Außenkessel verbunden ist. Die Membran wird zweckmäßig mit Wellen versehen und so groß gehalten, daß die auftretende Spannung unschädlich gemacht wird. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. An dem Boden des Innenkessels a sitzt ein Ablaufstutzen b. Von diesem führt ein Ablaufrohr c durch die Wandung des Außenkessels d nach außen. An dem Ablaufrohr c ist die Membran e befestigt, die unter Zwischenlage einer Dichtungsscheibe f und eines Flansches g durch Schrauben 1a an dem Außenkessel d befestigt wird.According to the invention, this drawback is avoided in that the Drain pipe through a membrane made of metal or another elastic material is connected to the external boiler. The membrane is expediently provided with waves and kept so large that the tension that occurs is rendered harmless. In the drawing shows an embodiment of the invention. On the floor of the inner vessel a there is a discharge nozzle b. From this leads a drain pipe c through the wall of the outer boiler d to the outside. The membrane is on the drain pipe c e attached, with the interposition of a sealing washer f and a flange g is fastened to the outer shell d by screws 1a.

Versuche haben gezeigt, daß durch diese nachgiebige Verbindung nach der Erfindung die erwähnten Übelstände völlig behoben werden.Tests have shown that this flexible connection after the invention, the abovementioned deficiencies are completely eliminated.
