Description

"Beheizungseinrichtung für Rohrleitungen Die Erfindung bezieht sich auf eine Beheizungseinrichtung für der Vereisung in ihrem Innern ausgesetzte Rohrleitungen, wie Wasserleitungen, Druckluftleitungen u.a. "Heating device for pipelines The invention relates to a heating device for pipelines exposed to icing inside them, such as water pipes, compressed air pipes, etc.

Es ist bekannt, daß nicht nur Wasserleitungen bei starkem Frost zufrieren, sondern auch Druckluftleitungen, besonders wenn sie Luft von hohem Druck führen, da diese im allgemeinen Feuchtigkeit enthält. Die angeschlossenen Geräte werden dadurch vollkommen stillgesetzt, was besonders bei Druckluftschaltern zu schwerwiegenden Folgen führen kann.It is known that not only water pipes freeze over in severe frost, but also compressed air lines, especially if they carry air at high pressure, as this generally contains moisture. The connected devices are thereby completely shut down, which is particularly serious with compressed air switches Can lead to consequences.

Man muß daher dafür sorgen, daß ein Einfrieren der Rohrleitungen möglichst: vermieden wird. hierfür ist eine elektrische Wärmequelle am besten geeignet.It is therefore necessary to ensure that the pipes do not freeze if possible: is avoided. an electrical heat source is best suited for this.

Ein von außen um die Rohrleitung gelegter elektrischer HeizLeiter wäre sehr aufwendig, da er gegen äußere Beschädrgungen geschützt werden und eine verhältnismäßig große Leistung haben müßte. Anders verhält es sich jedoch, wenn erfindungsgemäß in die Rohrleitung ein elektrischer Heizwiderstand in Form eines biegsamen, isolierten Drahtes oder einer Drahtwendel von der å jeweiligen Länge der Rohrleitung eingezogen ist. Dieser Heizwiderstand reicht voll aus, ein Vereisen der Rohrleitung zu verhindern. Außerdem behindert er den Durchfluß des strömenden Mediums kaum und ist auch keinen äußeren Beschädigungen ausgesetzt. Die aufgenommene Heizleistung ist außerdem vergleichsweise klein, da die Heizwirkung sich über die gesamte Rohrleitung gleichmäßig verteilt und in erster Linie dem Medium zugeführt wird und nicht auch wie bei einem äußeren Heizleiter dem umgebenden Erdboden.An electrical heating conductor placed around the pipe from the outside would be very expensive, since it would be protected against external damage and a should have a relatively high performance. The situation is different, however, if according to the invention in the pipeline an electrical heating resistor in the form of a flexible, insulated wire or a wire helix from the å respective Length of the pipeline is drawn in. This heating resistor is completely sufficient To prevent the pipeline from icing up. It also obstructs the flow of the flowing medium and is not exposed to any external damage. the The heating power consumed is also comparatively small because of the heating effect is evenly distributed over the entire pipeline and primarily the medium is fed and not, as in the case of an external heating conductor, to the surrounding soil.

Als Heizwiderstand eignet sich vorteilhaft ein Widerstand in Draht. oder Wendelform, der i bekannter Weise von einem pulverförmigen Isolierstoff umgeben in einem biegsamen Kupferrohr oder Kupfermantel untergebracht ist.A wire resistor is advantageously suitable as the heating resistor. or helical shape, which is surrounded by a powdered insulating material in a known manner is housed in a flexible copper tube or copper jacket.

In der Zeichnung ist in Fig. 1 ein Teil eines aufgeschnittenen Druckluftrohres 1 mit einem eingelegten Eleizleiterstück 2 dargestellt. Das Heizleiterstück hat die Form eines Drahtes, der unabgestützt In dem Rohrteil liegt.In the drawing, FIG. 1 shows a part of a cut open compressed air pipe 1 shown with an inserted electrical conductor piece 2. The heating element has the shape of a wire lying unsupported in the pipe part.

Fig. 2 zeigt einen Schnitt durch das Heizleiterstück R in vergrößertem Maßstab. Im Inneren eines biegsamen Kupferrohres 3 liegt von Isolierpulver 4 fest umgeben eine 'Jiderstandsdrahtwendel 5. Diese Einrichtung sorgt bei Anschluß an eine Stromquelle dafür, daß etwaige Feuchtigkeitsniederschläge nicht zu einer Vereisung des Rohrinnenraumes führen.Fig. 2 shows a section through the heat conductor piece R in an enlarged Scale. In the interior of a flexible copper tube 3, insulating powder 4 lies firmly surround a resistance wire coil 5. This device takes care of the connection a power source to ensure that any moisture deposits do not cause icing of the pipe interior.
