Description
Behälter zum Erhitzen von thermoplastischen Stoffen für den Straßenbau u. dgl. Container for heating thermoplastic materials for road construction and the like
Die Erfindung betrifft einen Behälter zum Erhitzen von thermoplastischen Stoffen, wie Asphalt, Bitumen od. dgl., für den Straßenbau u. dgl. mit einer wabenförmig ausgebildeten Doppelwand, durch die das Heizmittel geleitet wird. The invention relates to a container for heating thermoplastics Materials such as asphalt, bitumen or the like, for road construction and the like with a honeycomb formed double wall through which the heating medium is passed.
Bei einem bekannten Behälter dieser Art wird der Heizraum mit heißen Gasen beschickt. Um die erforderliche Wärmemenge auf das Schmelzgut übertragen zu können, muß wegen der geringen spezifischen Wärme der Gase mit einem recht hohen Temperaturgefälle gearbeitet werden, d. h. daß die heißen Gase Temperaturen aufweisen müssen, bei denen das Schmelzgut örtlich bereits verbrennt. Aus diesem Grunde ist bei der bekannten Bauart ein Rührwerk angeordnet, das sich absetzende Ablagerungen des Schmelzgutes abschabt, die dadurch also in das Schmelzgut eingemischt werden. Diese Ablagerungen - sind verbrannte Teile des Schmelzgutes. Ihr Einmischen führt zu einer Verschlechterung des Endproduktes, welche z. B. die Güte von mit ihm hergestellten Straßendecken schädlich beeinflußt. Es kommt somit darauf an, beim Beheizen ein Verbrennen von Schmelzgut auf jeden Fall zu vermeiden. Die Temperatur des Heizmittels muß also so niedrig sein, daß das Verbrennen von Schmelzgut überhaupt unmöglich ist. Dies bedeutet, insbesondere wenn der Behälterinhalt auf eine verhältnismäßig hohe Temperatur erwärmt werden soll, daß einerseits mit einem geringen Wärmegefälle gearbeitet werden muß. Andererseits muß jedoch eine ausreichende Wärmemenge zugeführt werden. In a known container of this type, the boiler room is hot Gases charged. To transfer the required amount of heat to the melt can, must because of the low specific heat of the gases with a very high Temperature gradients are worked, d. H. that the hot gases have temperatures where the melting material is already burning locally. This is why In the known design, an agitator is arranged, which deposits deposits scraped off the melting material, which is thus mixed into the melting material. These deposits - are burned parts of the melting material. Your meddling leads to a deterioration of the end product, which z. B. the goodness of manufactured with it Detrimental effects on road surfaces. It therefore depends on the heating one Avoid burning the melted material in any case. The temperature of the heating medium must therefore be so low that it is impossible to burn the melted material at all is. This means, especially when the container contents are on a proportionate basis high temperature is to be heated that on the one hand with a low heat gradient must be worked. On the other hand, however, a sufficient amount of heat must be supplied will.
Die Lösung dieses Problems besteht nach der Erfindung darin, daß die wabenförmige Doppelwand zwecks Verwendung von unter Druck stehendem Heißwasser als Heizmittel aus zu einem geschlossenen Rohrsystem aneinandergeschweißten Rohren besteht, durch die das Heißwasser geleitet wird. The solution to this problem is according to the invention that the honeycomb double wall for the use of pressurized hot water as heating means made of pipes welded together to form a closed pipe system through which the hot water is passed.
Durch das Heißwasser erfolgt ein mittelbares Be heizen, bei dem eine die Wärmeübertragung schädigende Dampfbildung vermieden ist und die trotz eines geringen Temperaturgefälles ausreichend ist. The hot water provides indirect heating in which one the heat transfer damaging vapor formation is avoided and despite one low temperature gradient is sufficient.
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 Fig. 2 ein senkrechter Schnitt durch einen stehenden Behälter. 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 FIG. 2 is a vertical section through a standing container.
Bei beiden Bauarten besteht der Teil der Behälterwandung 1, der beheizt werden soll, aus aneinandergeschweißten Rohren 2. Die Rohre 2 sind ein Teil eines geschlossenen Rohrsystems, durch das unter Druck stehendes Heißwasser als Heizmittel geleitet wird. In both types of construction there is the part of the container wall 1 that is heated is to be made of tubes 2 welded to one another. The tubes 2 are part of a closed pipe system, through the pressurized hot water as heating medium is directed.
