Bei Trommelfilter!! für Flüssigkeiten mit schwebenden Fremdkörpern, bei denen die Becher eines Becherwerks die Fremdkörper von dem Filtermantel abnehmen und austragen, besteht die Gefahr, daß die Filterfläche durch die Fremdkörper verschmiert wird. Die Erfindung- soll diesen Nachteil dadurch beseitigen, daß eine der Trommelniantclfilterfläche gegenüber angeordnete gesonderte Fördervorrichtung die Fremdkörper, ehe sie bis zur Austrittsstelle zu einem schlammigen Wulst zusammengedrängt werden, unter der Flüssigkeitsoberfläche erfaßt und in einer Richtung von der Filtertrommelmantelfläche weg direkt aus der Filtertrommelkammer her-, ausfördert. In welcher Richtung von der Filterfläche weg und direkt aus der Trommelkammer heraus dabei die Fremdkörper gefördert werden, ist gleichgültig. Zum Austra- gen der Fremdkörper kann z. B. ein Kratzenförderer verwendet werden, der im gleichen Sinne wie die Siebtrommel rotiert. Die Fremdkörper können auch dem Förderer durch einen Flüssigkeitsstrom zugetrieben werden, der künstlich dadurch hergestellt wird, daß man den Boden der Förderrinne durchlässig macht.With drum filters !! For liquids with floating foreign bodies, in which the cups of a bucket elevator remove the foreign bodies from the filter jacket and discharge them, there is a risk that the filter surface will be smeared by the foreign bodies. The invention is intended to eliminate this disadvantage in that a separate conveying device arranged opposite the drum filter surface collects the foreign bodies under the surface of the liquid before they are compressed into a muddy bead up to the exit point and in a direction away from the filter drum jacket surface directly from the filter drum chamber. , promotes. It does not matter in which direction the foreign bodies are conveyed away from the filter surface and directly out of the drum chamber. To remove the foreign body, z. B. a scraper conveyor can be used, which rotates in the same sense as the sieve drum. The foreign bodies can also be driven towards the conveyor by a flow of liquid which is artificially produced by making the bottom of the conveyor trough permeable.
Die Zeichnung zeig't ein Ausführungsbeispiel der Erfindung im Längsschnitt. Der Behälter α besteht aus der Filtertrommelkammer b und der Förderrinne c. Die Trommelkammer b nimmt die rotierende Trommel d auf. Der Mantel der Trommel d ist als FiI-terfläche ausgebildet. Die offenen Stirnseiten der Trommel sind gegen die Behälterwände abgedichtet. Innerhalb der Abdichtung liegt die Ausflußöffnung g. Gegenüber dem Trommelmantel .ist ein Förderer // eingebaut. Der Förderrinnenboden i ist als Rost oder Siebfläche ausgeführt.The drawing shows an embodiment of the invention in longitudinal section. The container α consists of the filter drum chamber b and the conveyor trough c. The drum chamber b houses the rotating drum d . The jacket of the drum d is designed as a filter surface. The open end faces of the drum are sealed against the container walls. The outflow opening g is located within the seal. A conveyor // is installed opposite the drum shell. The conveyor trough bottom i is designed as a grate or sieve surface.
Die mit Fremdkörpern beladene Flüssigkeit gelangt durch die Öffnung 0 in die Filtertrommelkammer b. Sie durchströmt die Trommclmantelfilterfläche e und verläßt durch die Ausflnßöffnungen g gereinigt den Apparat. Die zurückbleibenden Fremdkörper setzen sich unter der Flüssigkeitsoberfläche auf dem Boden der Trommelkammer ab oder bleiben in der Flüssigkeit schwebend. Sie werden vom Förderer erfaßt und auf der Rinne c aus dem Apparat gebracht. Durch die Löcher i im Förderrinnenboden fließt ein Teil der Flüssigkeit gereinigt ab. Dabei nimmt der Flüssigkeitsstrom die Fremdkörper mit und führt sie dem Förderer zu. Die Löcher im Förderinnenboden werden durch den darüber gleitenden Förderer gereinigt.The liquid loaded with foreign bodies passes through the opening 0 into the filter drum chamber b. It flows through the drum jacket filter surface e and leaves the apparatus cleaned through the outflow openings g. The remaining foreign bodies settle under the surface of the liquid on the bottom of the drum chamber or remain suspended in the liquid. They are picked up by the conveyor and brought out of the apparatus on the channel c. A portion of the liquid flows off in a purified manner through the holes i in the bottom of the conveyor trough. The flow of liquid takes the foreign bodies with it and feeds them to the conveyor. The holes in the inner floor of the conveyor are cleaned by the conveyor sliding over them.
