KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand vorliegender Erfindung ist eine Reinigungsvorrichtung für die bekannten, mit "Vacuum arbeitenden Trommelfilter.The present invention is a cleaning device for the known, with "Vacuum working drum filter.
Die auf ihrem cylindrischen Umfange mit einem Filtertuche bespannte Trommel A, in deren Inneren ein durch eine Luftpumpe hervorgebrachtes Vacuum herrscht, rotirt langsam in der Richtung des Pfeiles Z um ihre hohle Achse B in einem mit der zu filtrirenden Masse angefüllten, oben offenen Troge C. Das Vacuum bewirkt ein Durchsaugen der klaren Flüssigkeit und ein Anhaften der darin suspendirten Theile an dem Filtertuche, auf dem sich eine mehr oder weniger dicke Schicht des Niederschlages bildet. Auf seinem Wege durch die freie Luft wird dieser Niederschlag, der Filterkuchen, getrocknet, indem die Feuchtigkeit, die sich beim Austreten aus der Masse noch im Kuchen befindet, durch das Vacuum ins Innere der Trommel gesaugt wird. Bevor der Kuchen auf seinem Umlaufe wieder in den Trog eintaucht, wird er durch ein Messer D abgehoben, allmälig vorwärts geschoben und gezwungen, herabzufallen. Direct hinter dem Messer D, aber bereits im Troge in der Masse arbeitend, befindet sich eine Bürste E, welche durch eine Riemscheibe F in schnelle Umdrehung versetzt wird und dazu dient, den am Tuche haftenden Rest des Kuchens aufzulockern. Durch die Anordnung der Bürste innerhalb des Troges unterscheidet sich die Reinigungsvorrichtung von derjenigen nach Patentschrift 50301, bei welcher die Reinigungsbürste aufserhalb des Troges arbeitet, wobei die Aufrechterhaltung des Vacuums in Frage gestellt wird und eine so gründliche Reinigung des Filtertuches wie mittelst der in der Flüssigkeit arbeitenden Bürste gemäfs vorliegender Erfindung nicht erzielt werden kann.The cylindrical circumference of the drum A covered with a filter cloth, inside of which there is a vacuum created by an air pump, rotates slowly in the direction of the arrow Z around its hollow axis B in a trough C, which is open at the top and filled with the material to be filtered . The vacuum causes the clear liquid to be sucked through and the particles suspended in it to adhere to the filter cloth, on which a more or less thick layer of precipitate is formed. On its way through the open air, this precipitate, the filter cake, is dried in that the moisture that is still in the cake when it emerges from the mass is sucked into the interior of the drum by the vacuum. Before the cake dips back into the trough on its revolution, it is lifted off by a knife D , gradually pushed forward and forced to fall down. Directly behind the knife D, but already working in the mass in the trough, there is a brush E, which is set in rapid rotation by a pulley F and serves to loosen the remainder of the cake adhering to the cloth. The arrangement of the brush inside the trough differs the cleaning device from that according to patent specification 50301, in which the cleaning brush works outside the trough, whereby the maintenance of the vacuum is questioned and the cleaning of the filter cloth as thorough as with the one working in the liquid Brush according to the present invention can not be achieved.
