Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Entfernen von Restflüssigkeit aus Leitungen und Bauteilen von unter dem Gefrierpunkt betriebenen, wasserführenden Fahrzeugen, wie sie beispielsweise zur Reinigung von Ver- und Entsorgungsanlagen, die ohne oder mit Einbauten, beispielsweise mit Lichtwellenleiter (LWL) -Kabeln versehen sind, eingesetzt werden.The invention relates to a method and a device for removing residual liquid from pipes and components from below-freezing water-carrying vehicles, such as those for cleaning supply and Disposal systems without or with internals, for example with optical fibers (Fiber optic) cables are used.

Aufgabe der Erfindung ist es, ein Verfahren zur Entfernung von Restflüssigkeit aus Anlagenteilen wasserführender Fahrzeuge anzugeben, das eine Reinigung von ohne oder mit Einbauten, nicht begehbaren Ver- und Entsorgungsanlagen, bei Temperaturen unter dem Gefrierpunkt, mittels herkömmlicher Hochdruckspülfahrzeuge ermöglicht und eine Vorrichtung zur Durchführung des Verfahrens.The object of the invention is to develop a method for removing residual liquid To indicate parts of the system of water-bearing vehicles that can be cleaned without or with built-in, non-accessible supply and disposal systems, at temperatures below freezing, by means of conventional high-pressure washing vehicles and an apparatus for performing the method.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Restflüssigkeit unter Nutzung einer erzwungen Strömung aus Leitungen und Bauteilen entfernt und die Leitungen und Bauteile innen gleichzeitig getrocknet werden. Die erzwungene Strömung wird durch einen Vielzellenverdichter (9) direkt oder durch einen durch den Vielzellenverdichter (9) vorher im Schlammbehälter (10) des Reinigungsfahrzeuges erzeugten Unterdruck erzeugt.According to the invention the object is achieved in that the residual liquid under Use a forced flow away from pipes and components and the Lines and components are dried inside at the same time. The forced flow is directly by a multi-cell compressor (9) or by a Multi-cell compressor (9) previously in the sludge tank (10) of the cleaning vehicle generated negative pressure.

Bei der erfindungsgemäßen Vorrichtung ist zum einen in unmittelbarer Nähe eines Schlammbehälters (10) zum Absperren des Behälters (10) in der bestehenden Luftleitung ein Mehrwegeventil (11) eingebaut und eine zusätzliche Leitung (12) zum Zuströmen von Luft, die vorzugsweise vorgewärmt ist, an das Mehrwegeventil (11) angeschlossen und zum anderen zusätzliche ein Mehrwegeventil (13) in unmittelbarer Nähe des Vierwegeventils (4) in die Luftleitung eingebaut und an das Mehrwegeventil (13) eine weitere Leitung (14) zur Zuführung von Luft, die vorzugsweise vorgewärmt ist, angeschlossen.

Figure 00000001
In the device according to the invention, a multi-way valve (11) is installed in the immediate vicinity of a sludge tank (10) for shutting off the tank (10) in the existing air line and an additional line (12) for the inflow of air, which is preferably preheated the multi-way valve (11) is connected and, on the other hand, an additional multi-way valve (13) is installed in the immediate vicinity of the four-way valve (4) and to the multi-way valve (13) a further line (14) for supplying air, which is preferably preheated, connected.
