Description

Trocken-, Katinier- oder Drehtrommel Die Erfindung bezieht sich auf eine Trokken-, Kalzinier- oder Drehtrommel und hat die Anordnung eines Filters an deren Ausfallende zum Gegenstande, so daß der von den Heizgasen und Wrasen mitgetragene Staub oder die mitgetragene Asche zurückgehalten wird. Das Filter hat vorzugsweise die Form einer sich mit der Trommel drehenden Ringscheibe, so daß sich eine besondere Filtereinrichtung finit eigenem Antrieb erübrigt. Als Filterstoffe «-erden sich vielfach die zu Filtrierzwecken bekannten hochgebrannten, porösen Steine empfehlen. die gegen Hitze, Feuchtigkeit und chemische Einwirkung ziemlich unempfindlich sind.Drying, Katinier- or rotating drum The invention relates to a drying, calcining or rotating drum and has the arrangement of a filter their dropouts to the subject, so that the carried along by the heating gases and vapors Dust or ashes are retained. The filter preferably has the shape of an annular disc rotating with the drum, so that a special Filter device finitely own drive superfluous. As filter materials «-earth themselves often recommend the highly burned, porous stones known for filtering purposes. which are quite insensitive to heat, moisture and chemical effects.

Der Erfindungsgegenstand ist in der Zeichnung in einem Ausführungsbeispiel schematisch dargestellt.The subject of the invention is shown in the drawing in an exemplary embodiment shown schematically.

Die Abbildung zeigt eine Trocken-. Kalzinier- oder Drehtrommel i, an deren Ausfallende eine ringförmige Filterscheibe 2 befestigt ist. Die Wrasen gelangen aus der Trommel i in das Ausfallgehäuse 3 und müssen von hier durch die Filterscheibe 2 durchtreten, um in den Abzugkanal 4 zu gelangen. Hierbei hinterlassen die Gase den Staub auf der rechten Seite der Filterscheibe. Die Scheibe 2 dreht sich mit dem Trockner i und wird auf der linken Seite durch einen aus dem Rohr 5 austretenden dünnen Luftstrahl höherer Pressung bestrichen. Es findet also ein dauerndes Abheben des Staubes und Reinigen der Filterscheibe statt. Bei höherer Drehzahl der Trommel ist die Reinigung häufiger. also stärker. Der Staub fällt in den Raum 3, der nicht unter der Einwirkung des Gasstromes steht, und wird von hier mechanisch abgezogen. Die gereinigten Wrasen entweichen durch den Schacht ¢ in das Gebläse und von hier ins Freie.The illustration shows a dry. Calcining or rotating drum i, an annular filter disc 2 is attached to the dropout. The vapors get out of the drum i into the failure housing 3 and must from here through the Pass through the filter disk 2 to get into the exhaust duct 4. Leave behind here the gases remove the dust on the right side of the filter disc. The disc 2 rotates to the dryer i and is on the left through one from the tube 5 emerging thin air jet with higher pressure. So there is a permanent one Taking off the dust and cleaning the filter disc instead. At a higher speed of the Drum cleaning is more frequent. so stronger. The dust falls into room 3, which is not under the influence of the gas flow, and from here becomes mechanical deducted. The cleaned vapors escape through the duct ¢ into the fan and from here out into the open.
