Title
(DE) VORRICHTUNG ZUM ENTWÄSSERN VON SCHLAMM
(EN) DEVICE FOR DEHYDRATING SLUDGE
(FR) DISPOSITIF DE DESHYDRATATION DES BOUES
Abstract
(DE) Bei einer Vorrichtung zum Entwässern von Schlamm, wie er beispielsweise in Kläranlagen in Form von Dünnschlamm anfällt, wird vorgesehen, dass die Aufnahme für den Schlamm eine Siebfläche enthält, welche Öffnungen für den Durchtritt von Flüssigkeit besitzt. Die Siebfläche ihrerseits ist im wesentlichen kreisförmig ausgebildet und ist um eine senkrecht zur Siebfläche verlaufende Achse (21) drehbar. Die Achse (21) der Siebfläche (2) ist im Verhältnis zur Horizontalen geneigt und wird mittels einer Antriebsvorrichtung (3) in Drehung versetzt. Die scheibenförmige Siebfläche (2) ist in einem Behälter (11) angeordnet, der einen Boden (13) besitzt sowie eine Seitenwand (12), durch die eine Zuführung (4) für den Schlamm und eine Entnahme (41) für das abgetrennte Wasser führen.
(EN) The invention relates to a device for dehydrating sludge, such as occurs in sewage treatment plants in the form of dilute sludge. The receptacle for the sludge contains a filter surface which has openings for the passage of liquid. The filter surface in turn is substantially circular and can be rotated about an axis (21) which runs vertically to the filter surface. The axis (21) of the filter surface (2) is tilted in relation to the horizontal and is caused to rotate by a drive device (3). The disc-shaped filter surface (2) is located in a container (11) which has a base (13) and a lateral wall (12). A supply line (4) for the sludge and an outlet (41) for the separated water pass through said lateral wall.
(FR) L'invention concerne un dispositif permettant de déshydrater des boues telles les boues diluées précipitées dans des stations d'épuration. Le dispositif de réception des boues contient une surface tamis dotée d'ouvertures destinées au passage du liquide. La surface tamis, sensiblement circulaire, est pivotante autour d'un axe (21) perpendiculaire à la surface tamis. L'axe (21) de la surface tamis (2), incliné par rapport à l'horizontale, est entraîné en rotation par un dispositif d'entraînement (3). La surface tamis (2) en forme de disque est placée dans un contenant (11) qui possède un fond (13) et une paroi latérale (12) que traversent un dispositif d'alimentation (4) en boue et un dispositif de prélèvement (41) de l'eau séparée.
