Description

eine unmittelbar unter der Kupplung 3, das zweite etwa in der Mitte der Welle und das dritte in der Nähe des unteren Endes vorgesehen ist Die Wellenlager sind in einem Stützrohr 5 gehalten, das mittels eines Flansches 2 am Antriebsmotor 1 festgelegt ist. Pis Welle 6 ist durch eine Endabdichtung 10 am unteren Ende des geschlossenen Stützrohres abgedichtet one immediately below the clutch 3, the second roughly in the middle of the shaft and the third in the Near the lower end is provided The shaft bearings are held in a support tube 5, which means a flange 2 on the drive motor 1 is fixed. Pis shaft 6 is through an end seal 10 at the bottom Sealed the end of the closed support tube

Bei der Ausführungsform gemäß F i g. 1 ist unterhalb des unteren Wellenlagers 4 zwischen diesem Wellenlager und der Endabdichtung 10 in dem mit 9 bezeichneten Stützrohrabschnitt eine Kreiselpumpe 12 vorgesehen, die mit ihrem Gehäuse den Raum des Stützrohres 5 quer zur Längsrichtung dieses Stützrohres unterteilt, so daß das Wellenlager 4 von dem «5 Stützrohrabschnitt 9 durch das Gehäuse der Kreiselpumpe vollständig getrennt ist. Das Pumpenrad 8 der Kreiselpumpe ist auf der Welle 6 angeordnet und läuft ständig mit dieser mit. Die Kreiselpumpe 12 ist so angeordnet, daß ihr axialer Einlaß zur Endabdich- ac tung 10 hin gerichtet ist, während in dem radialen Auslaß ein Rückschlagventil 7 vorgesehen ist, über das die in den Stützrohrabschnitt 9 über die Endabdichtung 10 eindringende Flüssigkeit durch die Kreiselpumpe nach außen befördert werden kann. Das Rückschlagventil öffnet nur nach außen und dichtet somit gegen das außen vorhandene Mischgut bzw. gegen die außen vorhandene Flüssigkeit ab.In the embodiment according to FIG. 1 is below of the lower shaft bearing 4 between this shaft bearing and the end seal 10 in the one marked 9 designated support tube section a centrifugal pump 12 is provided, which with its housing the space of the Support tube 5 subdivided transversely to the longitudinal direction of this support tube, so that the shaft bearing 4 of the «5 Support tube section 9 is completely separated by the housing of the centrifugal pump. The impeller 8 of the The centrifugal pump is arranged on the shaft 6 and constantly runs with it. The centrifugal pump 12 is arranged so that their axial inlet to the end seal ac device 10 is directed towards, while a check valve 7 is provided in the radial outlet, over the penetrating into the support tube section 9 via the end seal 10 through the liquid Centrifugal pump can be conveyed to the outside. The check valve only opens to the outside and thus seals against the mixture present on the outside or against the liquid present on the outside.

Bei der Ausführungsform gemäß Fig.2 kann der Stützrohrabschnitt 9 zwischen dem unteren Welleniager4 und der Endabdichtung 10 ebenfalls über ein Rückschlagventil 7 entleert werden, wenn Flüssigkeit über die Endabdichtung 10 in diesem Raum eindringt. Das Hinausdrücken der eingedrungenen Flüssigkeit erfolgt durch Druckgas, das über einen mittels Ventil 13 absperrbaren Druckgasanschluß 14 in das abgedichtete Stützrohr 5 einführbar ist. Das Öffnen des Druckgasanschlusses erfolgt, nachdem durch einen in dem Stützrohrabschnitt 9 angeordneten Fühler 15 die eingedrungene: Flüssigkeit festgestellt wird. Das Ventil 13 kann als Handventil oder als ein durch den Fühler 15 gesteuertes automatisches Ventil ausgebildet sein. Der Drudegasanschluß 14 kann an beliebiger Stelle des Stützrohres 5 angeordnet sein.In the embodiment according to Figure 2, the Support tube section 9 between the lower shaft bearing4 and the end seal 10 can also be emptied via a check valve 7 if liquid penetrates through the end seal 10 in this space. Pushing out the penetrated liquid takes place by means of pressurized gas, which is fed into the sealed support tube 5 is insertable. The compressed gas connection is opened after through a sensor 15 arranged in the support tube section 9 which detects the penetrated liquid. The valve 13 can be designed as a manual valve or as an automatic valve controlled by the sensor 15 being. The drude gas connection 14 can be arranged at any point on the support tube 5.
