Description

Zellenloses Trommelfilter mit Seitentrog.Cellless drum filter with side trough.

Die Erfindung betrifft ein zellenloses Trommelfilter mit Seitentrog. Es sind schon seit langem zellenlose Trommelfilter bekannt, bei denen der gesamte Innenraum der Trommel unter Vakuum gesetzt wird0 Lediglich an der Stelle, an der der Filterkuchen abgenommen werden soll, wird ein Sektor angebracht, der gegen die Innenseite des Trommelmantels und gegen die Stirnseiten der Trommel abgedichtet ist, um an dieser Stelle Druckausgleich auf beiden Seiten des Filtermediums herstellen zu können Das unter dem Einfluß im Inneren der Trommel herrschenden Unterdrucks eintretende Filtrat wird durch ein feststehendes Siphonrohr, welches in der Trommel nach unten gerichtet ist und durch die Achse der Trommel nach außen geführt wird, aus der Trommel entfernt. Man kann hierzu entweder eine Filtratpumpe benutzen, oder man kann auch die Entleerung durch barometrisches Gefälle vornehmen, wenn das Filter entsprechend hooh aufgestellt wird. Das Vakuum erzielt man durch eine Vakuumpumpe, die mit dem Inneren der zellenlosen Trommel durch eine weitere Rohrleitung verbunden ist, die ebenfalls durch die Achse geführt wird. Im allgemeinen läuft diese zellenlose Trommel in einem unter ihr angebrachten Filtertrog, der die zu filtrierende Suspension aufnimmt Es ist natürlich auch möglich, an dieser Trommel einen sogenannten Seitentrog anzubringen, den man allerdings mehr bei Zellentrommelfiltern kennt, die in den Aufbereitungsbetriebes z.B. in Kohlewäschen arbeiten, wo man mit verhältnismässig rasch absetzenden Feststoffen zu tun hat. In Fälle, in denen sehr große Filtratmengen anfallen, könnten Schwierigkeiten auftreten, um das Siphonrohr zum Abführen des Filtrates, in der Achse des Filters unterzubringen.The invention relates to a cellless drum filter with a side trough. Cellless drum filters have been known for a long time, in which the entire Inside the drum is placed under vacuum only at the point where the filter cake is to be removed, a sector is attached, which is against the Inside of the drum shell and sealed against the front sides of the drum is to create pressure equalization on both sides of the filter medium at this point to be able to The negative pressure prevailing under the influence of the inside of the drum Entering filtrate is through a fixed siphon pipe, which is in the drum is directed downwards and is guided outwards through the axis of the drum, removed from the drum. You can either use a filtrate pump for this, or it is also possible to use the barometric gradient for emptying if the filter is set up accordingly hooh. The vacuum is achieved by a vacuum pump, which are connected to the interior of the cell-less drum by another pipe which is also passed through the axis. In general, this runs cellless Drum in a filter trough attached below it, which holds the suspension to be filtered It is of course also possible to have a so-called side trough on this drum to be attached, which is, however, more familiar with cell drum filters that are used in the Processing plant, e.g. work in coal washers, where you can work with relatively has to do with rapidly settling solids. In cases in them very much If large quantities of filtrate are produced, difficulties could arise around the siphon pipe to discharge the filtrate, to be accommodated in the axis of the filter.

Die vorliegende Erfindung schlägt deshalb vor, dieses Siphonrohr wegzulassen und das Filtrat durch den gelochten Mantel der Filtertrommel abfließen zu lassen. Zu diesem Zweck soll das Filter gemäss der Abbildung gebaut werden. In dieser Abbildung stellt 1 die gelochte Filtertrommel dar. Durch die Achse 2 wird das Verbindungsrohr 3 zu der Vakuumpumpe 4 geführt. An der gelochten Filtertrommel 1 ist der Seitentrog 5 angebaut, dem durch 6 die-zu filtrierende Suspension über den Einlaufkasten 7 zugeführt wird. Dieser Einlaufkasten 7 ist mit dem Wehr 8 und dem überlaufstutzen 9 verbunden. Im Inneren der Trommel findet sich der Sektor 10, der durch die Abdichtungen i und 12 gegen das Vakuum im Inneren der Trommel 1 abgedichtet ist. Durch die gelochte Trommel akann in diesen Sektor biuft eindringen und dadurch Druckausgleich auf beiden Seiten des Trommelmantels herstellen. Dadurch ist es möglich, den Pilterkuchen 13 mit der Abnahmewalze 14 von der Filteroberfläche abzunehmen. Durch das Spritzrohr 15 kann die Filteroberfläche etwas abgespritzt werden. Die Abdichtungen 12 und 16 bilden eine weitere Kammer, die durch eine in ihrer Weite verstellbare Öffnung 17 Verbindung mit dem Trommelinneren hat, so daß das im Trommelinneren anfallende Filtrat durch die Bohrungen der gelochten Trommel 1 in den Auffangkasten 18 abfließen kann.The present invention therefore proposes to omit this siphon pipe and to let the filtrate drain through the perforated jacket of the filter drum. For this purpose, the filter should be built according to the illustration. In this picture 1 shows the perforated filter drum. The connecting pipe is through the axis 2 3 to the vacuum pump 4. The side trough is on the perforated filter drum 1 5 grown, the suspension to be filtered through 6 via the inlet box 7 is fed. This inlet box 7 is with the weir 8 and the overflow nozzle 9 connected. Inside the drum is the sector 10, which is created by the seals i and 12 is sealed against the vacuum inside the drum 1. Through the perforated The drum can penetrate into this sector and thus pressure equalization on both Make sides of the drum shell. This makes it possible to make the pilter cake 13 remove with the take-off roller 14 from the filter surface. Through the spray pipe 15 the filter surface can be hosed down a little. The seals 12 and 16 form a further chamber, which is opened through an opening 17, which is adjustable in its width Has connection with the interior of the drum, so that the filtrate obtained in the interior of the drum can flow through the bores of the perforated drum 1 into the collecting box 18.

Von dort gelangt es durch den Stutzen 192 entweder zu einem barometrischen Fallrohr, oder zu einer Filtratpumpe, wobei auch die weite Öffnung 19 durch ein Ventil variabel ist.From there it passes through the connection 192 either to a barometric one Downpipe, or to a filtrate pump, where also the wide opening 19 is variable by a valve.

Die genannte Öffnung 17 kann man sehr weit gestalten, so daß keine Sorge besteht, daß auch große anfallende Filtratmengen abgeführt werden können.Said opening 17 can be made very wide, so that none There is concern that large amounts of filtrate may also be discharged.

Man kann diese Pilter auch als selbstsaugende Filter ohne Vakuumpumpe laufen lassen, wenn man den Filtratspiegel 20 in der Filtertrommel 1 sehr weit absenkt, so daß die Niveaudifferenz zwischen dem Suspensionsstand im Seitentrog 5 und dem Filtratstand im Inneren der Trommel 20 als Antriebskraft für die Filtration verwendet werden kann. @This Pilter can also be used as a self-priming filter without a vacuum pump let it run when the filtrate level 20 in the filter drum 1 is lowered very far, so that the level difference between the suspension level in the side trough 5 and the Filtrate level inside the drum 20 is used as a driving force for the filtration can be. @
