Abstract

Eine Stülpfilterzentrifuge weist eine, in einem Maschinengestell (2) drehbar gelagerte, freitragend in ein mit dem Maschinengestell (2) verbundenes Gehäuse (1) hineinragende Filtertrommel (16) auf, die einen mit Normal-, Über- oder Unterdruck beaufschlagbaren Schleuderraum (14) radial umschließt. Der Schleuderraum (14) ist an seiner Stirnseite mit einem Schleuderraumdeckel (25) verschlossen und auf der anderen Seite durch einen Schubboden (23) begrenzt. Die Filtertrommel (16) und der Schubboden (23) laufen gemeinsam um und werden translatorisch relativ zueinander bewegt um ein Filtertuch (22) umzustülpen, und abgetrennten Feststoff aus dem Schleuderraum (14) in einen Feststoffsammelraum (32) auszutragen. Am Schleuderraumdeckel (25) ist eine Einfüllöffnung (28) für einzubringende Medien, (Suspension, Waschflüssigkeit, usw.) vorgesehen, die bei geschlossenem Schleuderraum (14) von einem um seine Längsachse drehbar gelagerten Füllrohr (26) abgedichtet durchdrungen wird. Hierbei wird die starre Medienzufuhr durch ein mit ihr verbundenes in das drehbar gelagerte Füllrohr (26) eindringendes Mundstück (65) beendet. Dadurch entsteht ein Durchgang für die in den Schleuderraum (14) zu verbringenden Medien. Zwischen dem radial starren Mundstück (65) und dem umlaufenden Füllrohr (26) sind Lippendichtungen, vorzugsweise herkömmliche / handelsübliche Wellendichtungen mit Dichtlippen, angeordnet. Wobei durch die Art und Weise der Druckgaszufuhr sowie die gewählte Anordnung, die Dichtlippen auch bei Überdruck im Schleuderraum (14), durch den Gasüberdruck nicht belastet-, sondern entlastet werden. Infolgedessen laufen die Dichtungen im Betrieb verschleißarm und erreichen eine hohe Lebensdauer.

Figure imgaf001
An inverting filter centrifuge has a filter drum (16), which is mounted so as to be cantilevered in a machine frame (2) and projecting into a housing (1) connected to the machine frame (2), which has a centrifugal space (14) which can be acted upon by normal, overpressure or underpressure. encloses radially. The centrifugal chamber (14) is closed at its end face with a centrifugal chamber cover (25) and bounded on the other side by a sliding floor (23). The filter drum (16) and the sliding floor (23) run together and are translationally moved relative to one another to evert a filter cloth (22) and discharged solids from the centrifugal chamber (14) in a solids collecting space (32). A filling opening (28) for media to be introduced (suspension, washing liquid, etc.) is provided on the centrifugal chamber cover (25), which is sealed when the centrifugal space (14) is closed by a filling tube (26) rotatably mounted about its longitudinal axis. Here, the rigid media supply by a connected with her in the rotatably mounted filling tube (26) penetrating mouthpiece (65) is terminated. This creates a passage for the media to be transferred into the centrifugal space (14). Between the radially rigid mouthpiece (65) and the circumferential filling tube (26) lip seals, preferably conventional / commercial shaft seals with sealing lips arranged. Whereby by the way the compressed gas supply and the selected arrangement, the sealing lips are not burdened by overpressure in the centrifugal space (14), by the gas pressure, but relieved. As a result, the seals run during operation wear and achieve a long service life.
