Abstract
Vorrichtung zum Abdichten eines rotierenden Teiles gegenüber einem feststehenden Teil einer Rohrmühle über ringförmige Dichtelemente, die innerhalb eines Dichtringgehäuses (10) angeordnet sind, dadurch gekennzeichnet, dass die Dichtelemente aus Dichtschnüren (13) bestehen, die jeweils von einem Spannband (14) umschlossen und von diesem elastisch gegen eine rotierende Dichtfläche gedrückt sind, dass das Spannband (14) gegen Verdrehen in dem Dichtringgehäuse (10) gesichert ist und dass sich die Stoßkanten einer die Dichtfläche umgebenden Dichtschnur (13) in einem Abstand (20) gegenüberstehen.contraption for sealing a rotating part against a fixed part a tube mill via annular sealing elements, within a sealing ring housing (10) are arranged, characterized in that the sealing elements made of sealing cords (13), each surrounded by a strap (14) and are elastically pressed by this against a rotating sealing surface, the tensioning band (14) prevents it from twisting in the sealing ring housing (10). is secured and that the abutting edges of a surrounding the sealing surface Seal (13) at a distance (20) facing each other.
Description
Die Erfindung betrifft eine Vorrichtung zum Abdichten eines rotierenden Teiles gegenüber einem feststehenden Teil einer Rohrmühle mit den Merkmalen des Oberbegriffes des Patentanspruches 1.The The invention relates to a device for sealing a rotating Part opposite a fixed part of a tube mill with the features of the preamble of claim 1.

der
Der Erfindung liegt daher die Aufgabe zugrunde, eine Abdichtung für Rohrmühlen zu schaffen, die bei einer Inertisierung durch ein kondensierbare Bestandteile enthaltendes Gas unempfindlich gegenüber einer Taupunktunterschreitung ist.Of the The invention is therefore based on the object, a seal for tube mills create, when inertized by a condensable constituents containing gas insensitive to a dew point below is.
Zur Lösung dieser Aufgabe sind die Merkmale des Anspruchs 1 vorgesehen. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.to solution This object, the features of claim 1 are provided. advantageous Embodiments are described in the subclaims.
Wenn bei der erfindungsgemäßen Abdichtung Kondensat in das Dichtringgehäuse dringt, so besteht keine Gefahr, dass das Dichtelement verklemmt, weil die Dichtschnur in sich nachgiebig ist und durch das Spannband stets gegen die Dichtfläche angedrückt wird. Die Abdichtung bleibt trotz einer eventuellen Bildung von klebrigen Ablagerungen und Feuchtigkeit dicht.If in the seal according to the invention Condensate in the sealing ring housing penetrates, there is no danger that the sealing element jammed, because the sealing cord is yielding and through the strap always against the sealing surface pressed becomes. The seal remains despite a possible formation of sticky deposits and moisture tight.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher erläutert. Es zeigen:One embodiment The invention is illustrated in the drawing and will be described below explained in more detail. It demonstrate:
