Description

Es sind Schlauchfilter mit einer besonderen, die Reinigung der Spülluft bezweckenden Filtergruppe bekannt, bvei denen die Spülluft durch einen zweiten Ventilator in das Schlauchfilter hineingedrückt und der anfallende Staub aus dem für jede Filterabteilung vorgesehenen Auffangtrichter in einen alle Auffangtrichter einschließenden gemeinsamen Staubscammelraum gebracht und anschließend durch eine besondere Angetriebene Förderschnecke ausgetragen wird. Den Staubsammelraum und die Förderschnecke nebst ihrem Antrieb kann man ersparen, wenn man gemäß der Erfindung zweischen den Auffangtrichtern der Schlauchfilterabteilungen und dem für die Reinigung der Spülluft vorgescehen Staubabscheider eine pneumatische Förderleitung anordnetnet, die mittels des Spülluftstroms betreiben wird. Beispielsweise kann man den Ventilator des Schlauciifilters, der die Spülluft in das Schaluchfilter drückt; in das Förderrohr einschalten, in das die Auffangtrichter der Filterabteilungen des Schlauchfilters unmittelbar mit ihren Stutzen münden und das zu einem Staubabscheider führt, von dem aus das Luftabführungsrohr in den als staubluftverteilerkanal dienenden Hinterban des Staubfilters führen kann. There are bag filters with a special one that purifies the purge air intended filter group known, bvei which the purge air through a second fan pressed into the bag filter and the resulting dust out of the for each filter department provided collecting funnel in a common including all collecting funnels Dust collection area brought and then by a special driven screw conveyor is carried out. The dust collection chamber and the screw conveyor together with its drive can be saved if, according to the invention, the two collecting funnels Bag filter departments and the dust separator provided for cleaning the purge air arranges a pneumatic conveying line, which operate by means of the purge air flow will. For example, you can use the fan of the hose filter that controls the purge air presses into the tube filter; in the delivery pipe into which the collecting funnel the filter departments of the bag filter open directly with their nozzle and which leads to a dust collector, from which the air discharge pipe in the as Can lead dust air distribution channel serving rear rail of the dust filter.

In, der Zeichnung ist ein Ausführungsbeispiel dieses Staubefilters schematisch wiedergegeben. In, the drawing is an embodiment of this dust filter shown schematically.

Das neue Staubfilter, das in vier Abteilungen I, II, III und IV unterteilt ist, weist für jede Abteilung einen Staubsammelrumf a mit einem Saugstutzen b auf, in dem eine Dorsselklappe h eingebaut ist. Diese beim Filtervorgang des Staubfilters geschlossenen Drosselklappen k werden bei der Abreinigung einer Abteilung durch eine Schalt welle c geöffnet, die mit der allgemeinen Schaltwelled des St;aubfilters für Iden Filtervorgang durch einen Kettentrieb e oder eine andere geeignete Übertragungsvorrichtung in Bewegungszusammenhang steht. Die Filterabteilungen I bis III befinden jsich im Filtrierzustand, die Abteilung IV dagegen im Abreinigungsazustand. In dem Saugstutzen b der Abteilung IV ist die Drosselklappe k geöffnet, während die Drosselkappe m im Abführungsstutzen n der Filterabteilung IV zu den Sauggebläsen geschlossen ist. The new dust filter, which is divided into four departments I, II, III and IV is, has a dust collection drum a with a suction nozzle b for each department, in which a Dorssel flap h is installed. This during the filtering process of the dust filter closed throttle valves k are used when cleaning a department a switching shaft c opened, which with the general switching shaft of the St; aubfilters for the filtering process by means of a chain drive or another suitable transmission device is related to movement. The filter departments I to III are located in the Filtration state, Department IV, however, in the cleaning state. In the suction nozzle b of division IV, the throttle valve k is open, while the throttle cap m is closed in the discharge nozzle n of the filter compartment IV to the suction fans.

Die Sugstutzen b der vier Saugsammelrümpf a münden in ein zu einem besonderen Gebläse g führendes Rohr f. Die Ausblasleitung o des Gebläses g mündet in einen Vorabscheider h, von dem ein Abführungsrohr p in den als Staubluft- Verteilkanal dienenden Hinterbau i des Staubfilters führt. The Sugstutzen b of the four suction manifold a open into one to one Special blower g pipe f. The exhaust line o of the blower g opens into a pre-separator h, from which a discharge pipe p into the dust air distribution channel serving rear part i of the dust filter leads.

Während der Abreinigung der Filterabteilung IV saugt das Gebläse g den durch die offene Spülluft-. klappe q strömenden Spülluftstrom Idurch die Filterschläuche hindurch; dieser löst den Staub dort ab, fülhrt ihn durch den Staubsammelrumpf a, den anschließenden Saugstutzen b und das Rohr f aus dem Filtergehäuse ab und bringt ihn in den Vorabscheider h. Die in diesem Abscheider vom Staub getrennte Spülluft tritt in den Hinterbau i des Filters ein, um von den geringen Mengen des noch mitgeführten Staubes gereinigt zu werden. The fan sucks in during the cleaning of the filter compartment IV g through the open purge air. flap q flowing purge air flow I through the filter hoses through; this loosens the dust there, guides it through the dust collection body a, the adjoining suction nozzle b and the pipe f from the filter housing and brings it in the pre-separator h. The purge air separated from the dust in this separator enters the rear section i of the filter in order to avoid the small amounts of the still carried Dust to be cleaned.

Aus dem Vorabscheider h wird der abgeschiedene Staub in bekannter Weise abgesaugt oder an eine andere verwendungsstelle gebracht.The separated dust is known from the pre-separator h Sucked off or taken to another place of use.
