Description

Die Erfindung betrifft einen Behälter zum Erhitzen von thermoplastischen Stoffen, wie Asphalt, Bitumen od. dgl., für den Straßenbau u. dgl. mit einem an derBehälteraußenwand angeordnetenHeizraum, der als Wärmeübertragungsmittel Öl enthält, das durch ein durch von dem Öl umschlossene Rohre geleitetes Heizmittel erhitzt wird. The invention relates to a container for heating thermoplastics Materials such as asphalt, bitumen or the like, for road construction and the like The heating space arranged on the outer wall of the container, which contains oil as a heat transfer medium, which is heated by a heating medium passed through pipes enclosed by the oil will.

Bei einem bekannten Behälter dieser Art wird die Wärme dem Öl durch unmittelbares Beheizen mittels Feuergase zugeführt. Eine derartige Beheizung führt aber wegen der hohen Temperaturen der Gase zu örtlichen Überhitzungen des Öls, wodurch ein Verkoken des Öls eintritt. Hierdurch wird der Wärmeübergang von den Heizrohren auf das Öl verschlechtert, nach längerer Betriebszeit möglicherweise sogar völlig unterbunden. In a known container of this type, the heat is passed through to the oil direct heating by means of fire gases supplied. Such heating leads but because of the high temperatures of the gases to local overheating of the oil, which coking of the oil occurs. This will allow the heat transfer from the heating pipes on the oil, possibly even completely after a long period of operation prevented.

Die Erfindung geht von der Erkenntnis aus, daß das mittelbare Beheizen des Behälters nur dann erfolgreich ist, wenn das Öl einwandfrei bleibt. Es wurde erkannt, daß im Gegensatz zu der bekannten Bauart, die wegen der geringen spezifischen Wärme der Brenngase ein großes Temperaturgefälle erfordert, das Öl mit einem geringen Temperaturgefälle beheizt werden muß, insbesondere dann, wenn die Temperatur im Behälter selbst relativ hoch liegt, damit das Öl unbedingt an allen Stellen unterhalb seiner Verkokungstemperatur bleibt. The invention is based on the knowledge that indirect heating of the container is only successful if the oil remains flawless. It was recognized that in contrast to the known design, which because of the low specific Heat of the combustion gases requires a large temperature gradient, the oil with a small one Temperature gradient must be heated, especially when the temperature in the The container itself is relatively high so that the oil is absolutely underneath at all points its coking temperature remains.

Die Erfindung besteht darin, daß die Heizrohre zwecks Verwendung von unter Druck stehendem Heißwasser als Heizmittel zu einem geschlossenen Rohrsystem verbunden sind. The invention is that the heating pipes for use from pressurized hot water as heating medium to a closed pipe system are connected.

Hierdurch kann die erforderliche Wärmemenge bei geringem Temperaturgefälle übertragen werden; eine die Wärmeübertragung schädigende Dampfbildung wird durch eine auf die gewünschte Temperatur abgestimmte Wahl des Drucks des Heißwassers verhindert. This allows the required amount of heat with a small temperature gradient be transmitted; a formation of steam which damages the heat transfer is caused by a selection of the pressure of the hot water that is matched to the desired temperature prevents.

In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt. In der Zeichnung ist Fig. 1 ein Querschnitt durch einen liegenden Behälter nach der Erfindung und Behälter zum Erhitzen von thermoplastischen Stoffen für den Straßenbau u. dgl. Two exemplary embodiments of the invention are shown in the drawing. In the drawing, Fig. 1 is a cross-section through a lying container of the invention and Container for heating thermoplastic materials for road construction and the like

Fig. 2 ein senkrechter Schnitt durch einen stehenden Behälter. Fig. 2 is a vertical section through a standing container.

Bei beiden Bauarten wird der Behälter 1 durch unter Druck stehendes Heißwasser beheizt, das durch ein aus Rohren 2 gebildetes geschlossenes Rohrsystem geleitet wird. Die Rohre 2 liegen in einem Kasten, der mit Öl als Wärmeübertragungsflüssigkeit gefüllt ist. In both types of construction, the container 1 is pressurized Hot water heated by a closed pipe system formed from pipes 2 is directed. The tubes 2 lie in a box with oil as the heat transfer fluid is filled.
