Description

Umlaufendes Zellenfilter Die Erfindung bezieht sich auf umlaufende Filter mit mehreren Kunstschichten aus losem Filtermaterial.Rotary Cell Filter The invention relates to rotary cell filters Filter with several artificial layers made of loose filter material.

Es ist bekannt, derartige Filterschichten, wenn sie nach längerem Gebrauch ihre filtrierende Eigenschaft verloren haben, durch einstellbare Schabvorrichtungen o. dgl. abzunehmen und durch eine neue Filterschicht zu ersetzen. Weiter ist es bekannt, über einer Filterschicht eine abnehmbare Wand zur Abführung der Filterrückstände anzubringen. It is known to have such filter layers when they are used for a long time Have lost their filtering properties due to adjustable scrapers o. The like. Remove and replace with a new filter sheet. It is further known, a removable wall for discharging the filter residues over a filter layer to attach.

Gemäß der Erfindung wird eine zweite Kunstschicht auf einer die unterste Kunstschicht umschließenden endlosen Gewebebahn mittels einer besonderen Aufgabevorrichtung aufgebracht. Diese Schicht wird beim Auftauchen aus der Flüssigkeit durch eine Abnahmevorrichtung ganz oder teilweise entfernt, wonach die endlose Gewebebahn vor Aufbringen der neuen Kunstschicht an einer neuen Säuberungseinrichtung vorbeiläuft. According to the invention, a second layer of art on top of one becomes the bottom An endless web of fabric enclosing an artificial layer by means of a special feeding device upset. This layer is removed from the liquid by a removal device when it emerges completely or partially removed, after which the endless web of fabric before applying the new one Art layer passes a new cleaning facility.

Sowohl die Abnahmevorrichtung wie die Säuberungseinrichtung für die endlose Gewebebahn sind an sich bekannt.Both the removal device and the cleaning device for the endless webs of fabric are known per se.

Das neue Filter ist besonders geeignet für kontinuierliche Arbeitsweise, bei dem die Rohflüssigkeit mit einem Entfärbungsmittel, beispielsweise teilweise erschöpfter Kohle, eingemaischt wird, und bei dem eine Stoffentfärbung in einer einzigen Apparatur stattfindet, während bisher hierzu zwei hintereinandergeschaltete Apparatgruppen erfordert lich waren. The new filter is particularly suitable for continuous operation, in which the raw liquid with a decolorizing agent, for example partially exhausted coal, is mashed, and in which a fabric discoloration in one single apparatus takes place, while so far this two series-connected Apparatus groups were required.

Die Erfindung ist durch die Zeichnung beispielsweise in einem Querschnitt dargestellt. The invention is illustrated by the drawing, for example, in a cross section shown.

Zur Inbetriebnahme des zum Entfärben unreiner Flüssigkeiten besonders geeigneten Filters wird vor Einfüllen der Rohflüssigkeit in den Trog t die Filtertrommel g in Pfeilrichtung gedreht und dabei eine Kunstschicht k auf die Trommel bzw. auf das die Trommeloberfläche bedeckende Filtertuchm durch Aufgabevorrichtung at aufgegeben. In der Nähe des Trommelscheitels, zwischen dem Punkt, an dem die Trommel aus der Flüssigkeit austaucht, und der Aufgabevorrichtung a1, ist eine Abnahmevorrichtung in Gestalt eines Schabers st vorgesehen, der so eingestellt ist, daß die Kunstschicht k eine für die Schichtenentfärbung genügende Stärke erhält. Particularly for putting into operation for decolorizing impure liquids Suitable filter is t the filter drum before filling the raw liquid into the trough g rotated in the direction of the arrow and an artificial layer k on the drum or on the filter cloth covering the drum surface is applied by the feeding device at. Near the top of the drum, between the point at which the drum emerges from the Liquid emerges, and the feed device a1, is a removal device in the form of a scraper st provided, which is adjusted so that the art layer k is given a sufficient strength for the layer decolorization.

Die durch die Aufgabevorrichtungat aufgebrachte Kunstschicht wird innerhalb des Troges t von einem Filtertuch b umschlossen, das außerdem über Rollen 1l bis r3 läuft, von denen eine als Antrieb und eine andere als Spannrolle dienen kann. Auf dieses Tuch wird nach Aufbringen der Kunstschicht k durch eine Aufgabevorrichtung a2 vor der Eintauchstelle des Tuches eine zweite Kunstschicht 0 aufgebracht. Nunmehr wird die Rohflüssigkeit in den Trog t eingelassen und die Filterarbeit begonnen. Im Betriebe wird die auf dem Band b liegende obere Kunstschicht nach dem Austauchen aus der Flüssigkeit durch eine Abnahmevorrichtung abgenommen, die im Beispiel durch eine Gummiwalze w in Verbindung mit einem Schaber s2 gebildet ist. Danach wird das Band b fortlaufend, beispielsweise durch eine Waschdüsen und über einer Druckluftkammer D gesäubert; die Druckluft- und Flüssigkeitswaschvorrichtung können auch in eine der Leitrollen eingebaut werden, die dann aus gelochtem Blech bestehen und an der tYberlaufstelle des Bandes von innen mit Luft bzw. Wasser beaufschlagt werden. Bevor das gereinigte Band wieder in den Trog einläuft, wird erneut eine Kunstschicht o durch die Aufgabevorrichtung 42 aufgebracht; gegebenenfalls wird auch ein die Kunstschicht bildender Stoff (vorzugsweise erschöpfte Kohle) mit einem Teil der Rohflüssigkeit eingemaischt. The artificial layer applied by the application device is enclosed within the trough t by a filter cloth b, which also has rollers 1l to r3 runs, one of which serves as a drive and another as a tensioning pulley can. After the art layer has been applied, k is applied to this cloth by a feeding device a2 applied a second layer of art 0 in front of the immersion point of the cloth. Now the raw liquid is let into the trough t and the filter work begins. In the factory, the upper layer of art lying on belt b is removed after it has emerged removed from the liquid by a removal device, which in the example is by a rubber roller w is formed in connection with a doctor s2. After that, that will Band b continuously, for example through a washing nozzle and over a compressed air chamber D cleaned; the compressed air and liquid washing device can also be integrated into a the guide rollers are installed, which then consist of perforated sheet metal and are attached to the The overflow point of the belt can be exposed to air or water from the inside. Before the cleaned tape runs back into the trough, another layer of art or the like is created applied by the feeder 42; if necessary, the art layer will also be used forming substance (preferably exhausted coal) with part of the raw liquid mashed.

Es können auch Teile der unteren Kunstschicht k ständig oder zeitweilig durch die Abnahmevorrichtung al entfernt werden. Parts of the lower layer of art k can also be permanent or temporary can be removed by the removal device al.
