Description

Flüssigkeitsdichtung für stehende Rührwellen an Druckgefäßen Das Patent 503 442 betrifft eine Flüssigkeitsdichtung für stehende Rührwellen an Druckgefäßen, die dadurch gekennzeichnet ist, <laß an das Stopfbüchsengehäuse im Gefäßdeckel ein die Rührwelle umgebendes, bis unter den Flüssigkeitsspiegel eintauchendes Rohr dicht angeschlossen ist, so daß statt des Gases die Beschickungsflüssigkeit gegen die Stopfbüchse drückt.Liquid seal for standing agitator shafts on pressure vessels The patent 503 442 relates to a liquid seal for standing agitator shafts on pressure vessels, which is characterized by <let on the stuffing box housing in the vessel cover a tube that surrounds the agitator shaft and dips below the liquid level is tightly connected, so that instead of the gas, the feed liquid against the stuffing box presses.

Eine weitere Ausbildung der Erfindung besteht darin, daß man die -Beschickungsflüssigkeit nicht direkt, sondern unter Zwischenschaltung eines neutralen Gasraumes eine beliebige Dichtungsflüssigkeit gegen die Stopfbüchse drücken läßt. Dies geschieht, indem innerhalb des Tauchrohres ein an seinem unteren Ende geschlossenes, mit einer Dichtungsflüssigkeit teilweise angefülltes Rohr an der Welle absolut dicht befestigt ist. In dieses Rohr ragt ein drittes Rohr hinein, das ebenfalls am Stopfbüchsengehäuse dicht befestigt ist. Die Beschickungsflüssigkeit wird durch den im Gefäß herrschenden Gasdruck im äußeren Tauchrohr hochgedrückt und treibt nun mittels des zwischen den beiden Flüssigkeiten eingesperrten Gases die Dichtungsflüssigkeit in dem unten geschlossenen, mittleren Rohr abwärts und in dem inneren Tauchrohr aufwärts gegen die Stopfbüchse.Another embodiment of the invention consists in the fact that the loading liquid not directly, but any one with the interposition of a neutral gas space Can press sealing liquid against the stuffing box. This is done by within of the dip tube is closed at its lower end with a sealing liquid partially filled pipe is attached absolutely tightly to the shaft. In this pipe a third pipe protrudes into it, which is also tightly fastened to the stuffing box housing is. The feed liquid is caused by the gas pressure in the vessel pushed up the outer immersion tube and now propels between the two liquids by means of the trapped gas the sealing liquid in the bottom closed, middle Down the pipe and up in the inner dip pipe against the stuffing box.

In der Zeichnung ist eine Ausführungsform dargestellt, bei der weder die Beschickungsflüssigkeit mit .der Stopfbüchse noch das Gas mit der Dichtungsflüssigkeit in Berührung kommt. Hierbei sind beide Flüssigkeiten durch den neutralen Gasraum t getrennt. Auf der Welle e ist ein unten geschlossenes Rohr r dicht befestigt, das die Dichtungsflüssigkeit enthält. In dieses Rohr taucht eine rohrförmige Verlängerung s der Grundbüchse d ein. Außerdem führt das Tauchrohr g von der Grundbüchse d in die Beschickungsflüssigkeit. Läßt man nun auf die Beschickungsflüssigkeit einen Gasdruck wirken, so steigt diese im Rohr g nach oben. Die über dieser Flüssigkeit zusammengepreßte Luft bzw. ein anderes neutrales Gas im Raum t drückt alsdann auf die Dichtungsflüssigkeit im Rohr r, die letztere steigt dann im Rohr s nach oben und drückt gegen die Stopfbüchsenpackung.In the drawing, an embodiment is shown in which neither the charge liquid with the stuffing box nor the gas with the sealing liquid comes into contact. Here, both liquids are through the neutral gas space t separated. A tube r closed at the bottom is tightly fastened to the shaft e, which contains the sealing liquid. A tubular extension dips into this tube s of the basic sleeve d a. In addition, the immersion tube g leads from the basic sleeve d in the feed liquid. One lets one now on the charge liquid Acting gas pressure, it rises in the pipe g upwards. The one above this liquid Compressed air or another neutral gas in space t then presses on the sealing liquid in the pipe r, the latter then rises up in the pipe s and pushes against the gland packing.

PATENTANSPRUCH: Flüssigkeitsdichtung nach Patent 5034q2, dadurch gekennzeichnet, daß innerhalb des Tauchrohres (g) ein an seinem unteren Ende geschlossenes, zum Teil mit einer Dichtungsflüssigkeit gefülltes Rohr befestigt ist, in das von oben ein am Stopfbüchsengehäuse (d) befestigtes drittes Rohr (s) hineinragt, derart, daB die Beschickungsflüssigkeit zwischen dem Tauchrohr (g) und dem mittleren Rohr (r) sowie die Dichtungsflüssigkeit zwischen dem inneren Rohr (s) und der Rührwelle (e) durch den im Gefäß herrschenden Druck hochgedrückt wird, während zwischen den beiden Flüssigkeitssäulen ein Gasraum (t) verbleibt. PATENT CLAIM: Liquid seal according to patent 5034q2, characterized in that a tube, which is closed at its lower end and partially filled with a sealing liquid, is fastened inside the immersion tube (g), into which a third tube (s) fastened to the stuffing box housing (d) is attached from above. protrudes in such a way that the feed liquid between the immersion tube (g) and the middle tube (r) as well as the sealing liquid between the inner tube (s) and the agitator shaft (e) is pushed up by the pressure prevailing in the vessel, while between the two liquid columns a gas space (t) remains.
