KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist eine Einrichtung zum ununterbrochenen Reinigen des Filterstoffes bei sich drehenden Luftfiltertrommeln. The invention relates to a device for uninterrupted cleaning of the filter material with rotating air filter drums.
Gemäß der Erfindung wird zur Reinigung des Filterstoffes ein besonderer Gegenluftstrom unter Hochdruck durch ein düsenartiges, geschlitztes Rohr entgegen dem schwächeren Hauptluftstrom durch die Filter geblasen. Da ίο diese Gegenluft mit wesentlich größerem Druck durch die Filter geht als der Hauptluftstrom, wird der Filterstoff von den anhaftenden Unreinigkeiten befreit.According to the invention, a special counter-air flow is used to clean the filter material under high pressure through a nozzle-like, slotted pipe against the weaker one Main stream of air blown through the filters. Because ίο this counter air with much greater pressure Going through the filter as the main air flow, the filter material is removed from the adhering impurities freed.
Die Zeichnung zeigt die Erfindung, und zwar veranschaulichtThe drawing shows the invention, specifically illustrated
Fig. ι das Luftfilter in einem Schnitt nach der Linie A-B der Fig. 2 undFig. Ι the air filter in a section along the line AB of Fig. 2 and
Fig. 2 dasselbe in einem Querschnitt.Fig. 2 the same in a cross section.
Das Rohr α der Luftleitung mündet in einen Kasten b, in welchem eine Trommel c liegt, die mit dem Filterstoff d überzogen ist.The tube α of the air line opens into a box b, in which a drum c is located, which is covered with the filter material d.
Die Trommel ruht auf Rollen e, e und erhält vom Zahnrade f aus ihren Antrieb.The drum rests on rollers e, e and is driven by the toothed wheel f .
Nach dem Abzugsrohr g hin, aus welchem die gereinigte Luft austritt, ist die Trommel c offen, und innerhalb derselben liegt ein mit einem schmalen, düsenartig wirkenden Längsschlitz versehenes Rohr h, in welches durch ein Rohr i unter Hochdruck reine Luft gedrückt wird. Gegenüber dem Rohr h ist außerhalb der Trommel c ein zweites Rohr I angebracht, welches mit einem sich nach dem Rohr h zu erweiternden trichterförmigen Auffanglängsschlitz versehen ist.After the exhaust pipe g , from which the cleaned air exits, the drum c is open, and within it lies a pipe h provided with a narrow, nozzle-like acting longitudinal slot, into which pure air is forced through a pipe i under high pressure. Opposite the pipe h , a second pipe I is attached outside the drum c, which is provided with a funnel-shaped collecting slot which widens towards the pipe h.
Die Wirkungsweise der,· Vorrichtung ist folgende: The operation of the device is as follows:
Die staubige Luft tritt durch das Rohr a in den Kasten b ein. Bei ihrem Durchtritt durch den Filterstoff d der Trommel c lagert sich der Staub auf dem Filterstoff ab, worauf die Luft, gereinigt, durch das Rohr g aus der Trommel c wieder austritt.The dusty air enters through the pipe into the box a b a. As it passes through the filter material d of the drum c, the dust is deposited on the filter material, whereupon the air, cleaned, exits the drum c again through the tube g.
Bei der Drehung der Trommel c bewegt sich die Filterstoffbahn d langsam vor dem Luftkanal α vorbei. Sobald die Stoffbahn aus dem Bereiche des zu reinigenden Luftstromes gekommen ist, kommt sie in den Bereich des geschlitzten Rohres h, von welchem aus ein starker Strom reiner Luft von innen gegen den Filterstoff geblasen wird, der ihn von dem anhaftenden Staub wieder befreit. Der abgeblasene Staub gelangt in das Rohr /, von wo aus er nach einer Ablagerungsstelle befördert wird. · ■When the drum c rotates, the filter material web d slowly moves past the air duct α. As soon as the web of material has come out of the area of the air stream to be cleaned, it comes into the area of the slotted tube h, from which a strong stream of pure air is blown from the inside against the filter material, which frees it from the adhering dust. The blown dust gets into the pipe /, from where it is transported to a deposit point. · ■
