KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Der Filter gehört zu derjenigen Art, bei der eine Anzahl von Filterschläuchen im Kreise angeordnet ist und je ein Schlauch während der Abklopfperiode aus dem Strome der stauberfüllten Druckluft ausgeschieden wird. Die Zuführung der Staubluft zu den Schläuchen b b1 u. s. w. geschieht hierbei in an sich bekannter Weise von oben her bei u. Die Staubluft vertheilt sich durch die Vorkammern ^ und w wx u. s. w. in die Schläuche b b1 u. s. w. Die unteren Mündungen der Schläuche liegen in einem verschlossenen, trichterförmigen Gehäuse n, das durch eine beliebige Absperrvorrichtung y luftdicht verschlossen ist. Letztere öffnet sich entweder unter der Last des angesammelten Staubes selbstthätig oder wird je nach Bedarf geöffnet. Die Schlauchmündungen sind durch Ventile (Klappen) χ χ1 u. s. w. verschlossen, die folgenden Zweck haben:The filter is of the type in which a number of filter hoses are arranged in a circle and one hose is separated from the flow of dust-filled compressed air during the tapping period. The supply of the dust air to the hoses bb 1 etc. takes place in a manner known per se from above at u. The dust air is distributed through the antechambers ^ and ww x etc. into the hoses bb 1 etc. The lower mouths of the hoses are closed , funnel-shaped housing n, which is hermetically sealed by any shut-off device y. The latter either opens automatically under the load of the accumulated dust or is opened as required. The hose openings are closed by valves (flaps) χ χ 1 etc., which have the following purpose: Während der Abklopfung, die durch eine beliebige, hier nicht näher erläuterte Vorrichtung erfolgen kann, wird der Zutritt der Druckluft zu dem betreffenden Schlauche durch den cylindrischen Schieber ν abgesperrt. Da dann in dem abzuklopfenden Schlauche kein Ueberdruck mehr herrscht, so würde aus dem Räume η Druckluft von unten her in den Schlauch und durch dessen Wände nach aufsen strömen. Hierdurch würde der Staub fest angeprefst und seine Trennung von der Schlauchwand erschwert werden. Dies wird durch die Klappen χ x1 u. s. w. verhindert. Denn da im Innern der übrigen, nicht abgesperrten Schläuche ein Ueberdruck herrscht, so pflanzt sich dieser durch die offen stehenden Klappen in den Raum η fort und drückt die Klappe desjenigen Schlauches, der zur Zeit abgeklopft wird und deshalb aus dem Druckluftstrome ausgeschaltet ist, zu, so dafs die Rückströmung von Luft verhindert wird.During the knocking, which can be done by any device not explained in detail here, the access of the compressed air to the hose in question is blocked by the cylindrical slide ν. Since then there is no longer any excess pressure in the hose to be tapped, compressed air would flow out of the space η from below into the hose and out through its walls. This would firmly press the dust and make it more difficult to separate it from the hose wall. This is prevented by the flaps χ x 1 etc. Because there is overpressure inside the other, not shut off hoses, it propagates through the open flaps into the space η and pushes the flap of the hose that is being knocked off at the moment and is therefore switched off from the compressed air flow, so that the backflow of air is prevented. Pate ν τ-An SPRU ch:
Ein Schlauchfilter mit im Kreise angeordneten, während der Abklopfperiode aus dem Staubluftstrom ausgeschalteten Filterschläuchen mit oberer Druckluftzuführung, dadurch gekennzeichnet, dafs die unteren Mündungen der Schläuche durch Ventile Ix x1. .. .) abgeschlossen sind, von denen jedesmal diejenige, die dem jeweilig abzuklopfenden Schlauche angehört, durch die aus den übrigen Schlauchmündungen in den gemeinsamen Entleerungsraum (n) tretende Druckluft geschlossen wird.
Godfather ν τ-An SPRU ch:
A bag filter with filter bags arranged in a circle, switched off from the dust air flow during the knocking period, with an upper compressed air supply, characterized in that the lower mouths of the tubes are provided with valves Ix x 1 . ... ) are completed, of which each time the one belonging to the respective hose to be tapped is closed by the compressed air emerging from the other hose openings into the common emptying space (s).
