Description

Abdeckvorrichtung für Saugzellendrehfilter Es ist bekannt, bei Drehfiltern ein die Trocknungszone abdeckendes, undurchlässiges, mit der Filtertrommel umlaufendes, endloses Band zu verwenden, welches gegenüber den durchlässigen Bändern den Vorteil besitzt, daß ein höheres Vakuum und damit eine höhere Trockenwirkung erreicht wird. Die undurchlässigen Ltmiaufbänder haben aber andererseits den erheblichen Nachteil, daß ein Auswaschen des Filterkuchens mit Wasser oder anderen Flüssigkeiten nicht möglich ist.Covering device for rotary suction cell filters It is known for rotary filters an impermeable one that covers the drying zone and rotates with the filter drum, to use endless belt, which has the advantage over the permeable belts possesses that a higher vacuum and thus a higher drying effect is achieved. On the other hand, the impermeable adhesive tapes have the considerable disadvantage that washing out the filter cake with water or other liquids does not is possible.

Weiterhin weisen alle mit umlaufenden Åbdeckbändern arbeitenden Drehfilter den Übel. stand auf, daß die Reinigung der Filterfläche während des Betriebes fast unmöglich ge. macht ist, weil das umlaufende Band nahezu die ganze obere Hälfte der Filtertrommel bedeckt. Furthermore, all rotary filters that work with circumferential cover belts have the evil. got up that cleaning the filter surface during operation almost impossible ge. power is because the surrounding belt almost covers the entire upper half the filter drum covered.

Die Erfindung betrifft nun eine Anordnung des Abdeckbandes, welche gestattet, sowohl den Fiiterkuchen zu waschen, als auch eine Reinigungsvorrichtung für die Filterfläche anzubringen. The invention now relates to an arrangement of the cover tape which allows both the washing of the filter cake and a cleaning device for the filter surface.

Das durch Leit- und Preßwalzen e, / in bekannter Weise geführte endlose Band b wird durch die LeitwaJze g an einer beliebigen Stelle der Trommeln, zweckmäßig im Scheitel, so geführt, daß ein tunnelartiger Hohlraums über der Filterfläche entsteht. The endless e, / guided in a known manner by guide and press rollers Belt b is expedient by the guide roller g at any point on the drums in the apex, guided so that a tunnel-like cavity is created above the filter surface.

In diesen können leicht aus Brausen oder Düsen bestehende Wasch- und Spülvorrichtungen C1 und C, angebracht werden. Washbasins consisting of showers or nozzles can easily be and flushing devices C1 and C, may be attached.

Bei zu filtrierenden Rohstoffen, die eine öftere Reinigung der Filterfläche notwendig machen, ist in diesem Tunnel eine Bürstenwalze d untergebracht, die durch entsprechende bekannte Vorrichtungen zur Vornahme der Reinigung auf die Filterfläche gesenkt bzw. während des Filtervorganges von der Filterfläche abgehoben werden kann. Die Bürstenwalze d wird durch einen auf der Zeichnung nicht gezeigten Antrieb derart in Drehung versetzt, daß die Drehrichtung gleich oder entgegengesetzt der Trommelumdrehung ist. In the case of raw materials to be filtered, frequent cleaning of the filter surface make necessary, a brush roller d is housed in this tunnel, which through corresponding known devices for performing cleaning on the filter surface can be lowered or lifted off the filter surface during the filtering process. The brush roller d is driven by a drive not shown in the drawing set in rotation that the direction of rotation is the same or opposite to the rotation of the drum is.

Zur Unterstützung der Reinigung kann mittels der Vorrichtungen C1, C2 Wasser oder eine andere die Reinigung fördernde Flüssigkeit, z. B. diinne Säure, auf die Trommelfilterfläche aufgebracht werden. To support the cleaning, the devices C1, C2 Water or another liquid that promotes cleaning, e.g. B. thin acid, be applied to the drum filter surface.

Der durch das Abdeckband b, das aus undurchlässigem Baustoff, vorzugsweise z. B. By the cover tape b, which is made of impermeable building material, preferably z. B.

Gummi, besteht, gebildete Tunnel h schützt die Apparatur gegen das Bespritzen mit Wasser, Säure oder anderen Flüssigkeiten durch die sich drehende Bürste d.Rubber, consists, formed tunnel h protects the apparatus against that Splashing with water, acid or other liquids from the rotating Brush d.
