Claims (10)

1. Vorrichtung zum Führen von an einer Papiermaschine anfallendem Siebwasser (SW) mit mindestens einer Strömungsumlenkung (1, 2), welche einen Anströmungs- und einen Abströmungsbereich enthält und so gestaltet ist, daß die Anströmungsrichtung (A) des Siebwassers (SW) um einen Umlenkungswinkel (α) von mindestens 45° in der Horizontalen oder Vertikalen auf die Abströmungsrichtung (B) verändert wird, dadurch gekennzeichnet, daß die Vorrichtung mindestens eine Strömungsbarriere (3, 4) aufweist, welche so angeordnet ist, daß sie unterhalb des Niveaus (5) liegt, das das Siebwasser (SW) bei Betrieb der Vorrichtung hat.1. Apparatus for guiding white water (SW) accumulating on a paper machine with at least one flow deflection ( 1 , 2 ) which contains an inflow and an outflow area and is designed such that the direction of flow (A) of the white water (SW) is around The deflection angle (α) is changed from at least 45 ° in the horizontal or vertical to the outflow direction (B), characterized in that the device has at least one flow barrier ( 3 , 4 ) which is arranged such that it is below the level ( 5 ) is that the white water (SW) has when operating the device. 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Strömungsbarriere (3, 4) im Abströmungsbereich der Vorrichtung angeordnet ist.2. Device according to claim 1, characterized in that the flow barrier ( 3 , 4 ) is arranged in the outflow region of the device. 3. Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß die Strömungsbarriere (3) ein horizontal liegender Zylinder ist, der quer zur Abströmungsrichtung (B) angeordnet ist und einen kreisförmigen oder ovalen Querschnitt aufweist.3. Apparatus according to claim 1 or 2, characterized in that the flow barrier ( 3 ) is a horizontally lying cylinder which is arranged transversely to the outflow direction (B) and has a circular or oval cross section. 4. Vorrichtung nach Anspruch 1, 2 oder 3, dadurch gekennzeichnet, daß die Höhe der Strömungsbarriere (3) mindestens 15% der Höhe des Strömungsquerschnittes im Abströmbereich beträgt.4. Apparatus according to claim 1, 2 or 3, characterized in that the height of the flow barrier ( 3 ) is at least 15% of the height of the flow cross section in the outflow area. 5. Vorrichtung nach einem der voranstehenden Ansprüche, daß die Strömungsbarriere (3, 4) einer horizontalen Strömungsumlenkung (1) zugeordnet ist.5. Device according to one of the preceding claims, that the flow barrier ( 3 , 4 ) is associated with a horizontal flow deflection ( 1 ). 6. Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß die Strömungsbarriere (4) eine Gitterstruktur aufweist.6. The device according to claim 1 or 2, characterized in that the flow barrier ( 4 ) has a lattice structure. 7. Vorrichtung nach Anspruch 6, dadurch gekennzeichnet, daß die Strömungsbarriere (4) waagerecht angeordnet ist.7. The device according to claim 6, characterized in that the flow barrier ( 4 ) is arranged horizontally. 8. Vorrichtung nach Anspruch 6, dadurch gekennzeichnet, daß die Strömungsbarriere (4) schräg zur Horizontalen angeordnet ist.8. The device according to claim 6, characterized in that the flow barrier ( 4 ) is arranged obliquely to the horizontal. 9. Vorrichtung nach Anspruch 6, 7 oder 8, dadurch gekennzeichnet, daß die Strömungsbarriere (4) so angebracht ist, daß das Gitter zusätzlich zu seiner hydraulischen Funktion als Sicherheitseinrichtung dient, mit der offen liegende Teile der Siebwasserführung nach oben abgedeckt sind.9. Apparatus according to claim 6, 7 or 8, characterized in that the flow barrier ( 4 ) is mounted so that the grid serves in addition to its hydraulic function as a safety device with which exposed parts of the white water are covered upwards. 10. Vorrichtung nach Anspruch 6, 7, 8 oder 9, dadurch gekennzeichnet, daß sich das Gitter oberhalb eines hydraulischen Fallschachtes befindet.10. The device according to claim 6, 7, 8 or 9, characterized, that the grille is above a hydraulic chute.
