Abstract

Rotary scraper boards for use in elongated sedimentation tanks, to scrape settled sludge, partic. activated sludge, away from the ends of the tank, can be rotated towards the direction of travel of the scraper bridge in the end zones of the tank and are adjustable in the zones and thereby displace the residual sludge directly in front of the sludge suction device. More esp., the boundary as well as the pressure between the scraper boards and the tank bottom can be adjusted without causing increased wear of the board or rubber. Sludge can be completely removed from the ends of the sedimentation tank; the scraper boards are easily removed from the tank, e.g. for inspection.

Description

Drehschildräumer für Mängsabsetzbecken Für Längsabsetzbecken mit starkem Schlammanfall,z.B.Rotary shield scraper for male sedimentation basins For longitudinal sedimentation basins with strong Sludge spill, e.g.

Belebtschlammbecken,wer#en bekanntlich Räumerbrücken mit Pendelschilden eingesetzt,#ie den Nachteil eines sehr hohen Gummiverschleißes haben.Es sind ferner Räumerbrücken mit klapp- oder wabenförmigen Schilden bekannt,#ie aber den Nachteil haben,daß an den Beckenenden der Schlamm ungeräumt bleibt und die Schilde zu Inspektionszwecken nur schwer heraushebbar sind.Activated sludge basins are known to have scraper bridges with pendulum shields are used, # they have the disadvantage of very high rubber wear Räumerbrücken with folding or honeycomb shields known, but the disadvantage have that the sludge remains uncleared at the pool ends and the shields for inspection purposes are difficult to lift out.

Die Erfindung vermeidet die beschriebenen Nachteile dadurch,daß ein starres Drehschild (0) auf die Längsräumerbrücke montiert wird,das in der Höhe (1) zur Beckensohle wie auch im Anstellwinkel (2) zur Fahrtrichtung beliebig durch bekannte Vorrichtungen eingestellt werden kann.Das bedeutet ferner,#aß mit dem Räumschild spezifisch leichter und schwerer Schlamm ohne besondere Neigungen oder Abschrägungen in der Beckensohle einwandfrei geräumt werden kann.Eine entsprechende Beckengestaltung (3) ist nur an den Enden der Becken,an der das Schild gedreht wird,notwendig.Durch die Drehung des Schildes im Bereich (4) gegen die Bahrtrichtung wird auch der letzte Rest Schlamm vor die Absaugvorrichtung (5) - Druckluftheber oder Pumpe - geschoben,wobei diese erforderlichenfalls mitverstellt wird.Die Drehung des Schildes mit der Vorrichtung (6) wie auch die Verstellung der Pumpe im Bereich (10) mit der Vorrichtung (7) kann über bekannte Arten wie Hand-,Elektro- ,Hydraulik- oder Pneumatikantrieb erfolgen.The invention avoids the disadvantages described in that a rigid rotary shield (0) is mounted on the longitudinal scraper bridge, which is at the height (1) to the bottom of the pelvis as well as in the angle of attack (2) to the direction of travel by any known Devices can be adjusted. This also means, # ate with the dozer blade specifically light and heavy sludge without any particular inclinations or bevels can be properly cleared in the bottom of the pool (3) is only necessary at the ends of the basin where the shield is rotated the rotation of the shield in area (4) against the direction of travel is also the last Remaining sludge in front of the suction device (5) - compressed air lifter or pump - pushed, whereby This is adjusted if necessary. The rotation of the shield with the device (6) as well as the adjustment of the pump in the area (10) with the device (7) take place via known types such as manual, electric, hydraulic or pneumatic drive.

Die Schildhalterung selbst besteht aus einem Rohr,welches an einem Kugeldrehkranz auf der Brücke befestigt ist.The shield holder itself consists of a tube which is attached to a The slewing ring is attached to the bridge.

Durch eine Trennstelle des Rohres,eben unterhalb der Brücke,in Form von 2 Flanschen mit Schnellverbindung (8), kann das Schild mittels Hubvorrichtung (9) leicht über die Beckenkrone herausgehoben werden.Through a separation point in the pipe, just below the bridge, in shape of 2 flanges with quick connection (8), can use the sign Lifting device (9) can be lifted out slightly over the pelvic crown.

Weitere Merkmale der Erfindung sind Gegenstand der Unteransprüche.Further features of the invention are the subject of the subclaims.

Die Erfindung mit vorgenannten Ausführungen sind in der beiligenden Zeichnung beispielhaft dargestellt und zwar zeigt Abb. 1 einen Längsschnitt mit der Verstellvorrichtung (7) für die Saugvorrichtung (5) im Bereich (10),die Hubvorrichtung (9) für das Drehschild und die Beckengestaltung am Ende (3).The invention with the aforementioned embodiments are in the attached Drawing shown by way of example, namely Fig. 1 shows a longitudinal section the adjusting device (7) for the suction device (5) in the area (10), the lifting device (9) for the rotating shield and the pool design at the end (3).

Abb. 2 einen Querschnitt mit Drehschild (0) und Verstellung im Bereich (1) sowie die Schnellschlußverbindung (8) und die Saugvorrichtung (5).Fig. 2 shows a cross-section with rotary shield (0) and adjustment in the area (1) and the quick release connection (8) and the suction device (5).

Abb. 3 einen Grundriß mit Drehschild (0) und Verstell -vorrichtung (6) für den Bereich (2) sowie Verdrehung im Bereich (4) und die Beckengestaltung am Ende (3).Fig. 3 is a plan with a rotating plate (0) and adjusting device (6) for area (2) as well as twisting in area (4) and the pool design at the end (3).

Claims (5)

Patentansprüche Claims C1 Drehschildräumer für tängsabsetzbecken mit dem auch der letzte Rest Schlamm an den Beckenenden geräumt werden kann, dadurch gekennzeichnet,daß das im Bereich (1) und (2) einstellbare Bodenschild (0) am Ende des Beckens (3) gegen die Fahrtrichtung dreht (4) und hierbei den Rest Schlamm direkt vor die Saugvorrichtung (5) schiebt.C1 rotary shield scraper for longitudinal settling basins with the last one Remaining sludge can be cleared at the pool ends, characterized in that the bottom shield (0) at the end of the basin (3), adjustable in areas (1) and (2) rotates against the direction of travel (4) and the rest of the sludge directly in front of the suction device (5) pushes. 2.
