Abstract

A dry dust or power discharge device is used. It is incorporated in filtering systems used in mines to reduce and control dust hazards. The discharge device has an outer housing (1) and there is a filter body (2) in the centre of this. The filter is an ordinary bag filter and it is installed above a hopper with a rotating system of vanes (3) at the bottom, passing the dust into a tapering conveyor pipe containing an archimedean screw (4). Water is introduced at several points (5) along the conveyor to reduce the dust to mud. The screw is driven by a motor (6) at the end of the tube remote from the outlet.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

"Trockenstaubaustrag vorzugsweise für Bergbaufilter mit Naßagglomerationspumpen Zur Staubbekämpfung im Bergbau werden kleinbauende Filter benötigt."Dry dust discharge preferably for mining filters with wet agglomeration pumps Small filters are required to control dust in mining.

Der Austrag von abgerütteltem oder abgeblasenem Staub aus Trockenfilteranlagen muß zweckdienlich mit einer Benetzungsvorrichtung versehen werden, um den ausgetragenen Staub nicht wieder den Wettern bei hoher Luftgeschwindigkeit zu übergeben und dadurch wiederum eine Staubbelastung zu erzeugen.The discharge of dust that has been shaken off or blown off from dry filter systems must expediently be provided with a wetting device in order to avoid the discharged Dust does not pass back to the weather at high air speed and thereby in turn to generate a dust load.

Aus diesem Grund wird erfindungsgemäß vorgeschlagen, eine Vorrichtung zu verwenden, die die absolute Garantie gibt, mit kleinbauenden Elementen den Staubaustrag feucht garantieren zu können und den Staub über kleine Staubleitungen dem Förderband zum Beispiel zuzuführen.For this reason, the invention proposes a device to use, which gives the absolute guarantee of dust discharge with small-sized elements to be able to guarantee moist and the dust via small dust lines to the conveyor belt for example feed.

In der beiliegenden Zeichnung ist dargestellt mit 1) ein Trockenfiltergehäuse, mit 2) ein filternder Körper, z.B. Schlauchfilter, mit 3) die Staubaustragsschnecke, mit 4) eine Schlammförderpumpe, mit 5) der Wasseranschluß, mit 6) der Elektroanschluß des Motorantriebs.In the accompanying drawing is shown with 1) a dry filter housing, with 2) a filtering body, e.g. bag filter, with 3) the dust discharge screw, with 4) a sludge pump, with 5) the water connection, with 6) the electrical connection of the motor drive.

Die erfindungsgemäße Ausführung arbeitet wie folgt Strom und Wasser sind miteinander so über ein Schaltwerk verbunden, daß nur bei anstehendem Wasserdruck der Antrieb der Schlammförderpumpe mit Energie versorgt wird.The embodiment according to the invention works as follows: electricity and water are connected to each other via a switching mechanism that only when there is water pressure the drive of the sludge pump is supplied with energy.

Diese Energie kann Strom oder auch Druckluft sein.This energy can be electricity or compressed air.

Jedoch muß erfindungsgemäß gewährleistet sein, daß bei Anlauf der Schlammförderpumpe (4) wirklich gewährleistet ist, daß Wasser in den Verdrängungskörper einfließt, wodurch das von der Förderschnecke eingebrachte Staubgut in der Pumpe angefeuchtet und über eine Schlauchleitung z.B. auf das Laufwerk des Förderbandes abgepumpt werden kann.However, according to the invention it must be ensured that when starting the Sludge pump (4) is really guaranteed that water in the displacement body flows in, whereby the dust brought in by the screw conveyor in the pump moistened and via a hose line e.g. on the drive of the conveyor belt can be pumped out.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten und beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, einen Staubaustrag hinter Trockenfilteranlagen, vorzugsweise für den Bergbau, so zu gestalten, daß das Staubaustragsorgan, z.B. Förderschnecke oder Kratzbandförderer, das trockene staubförmige Material, einer Schlammförderpumpe zuführt, in die bei Betrieb unter Einschaltung eines Garantieflüssigkeitsschalters nur eine Förderung erfolgt, wenn ein genügend hoher Wasserdruck ansteht. Durch diese Anordnung ist die Gewähr gegeben, daß die Schlammförderpumpe nicht trocken läuft und dadurch a) nicht zerstört wird und b) der Staub aufgrund dieser Zwangsschaltung zwangsläufig als nicht staubende, feuchte Masse ausgetragen wird, wobei kleine Schlauchleitungen Anwendung finden können und nicht über Naßförderschnecken große starre unhandliche Fördertröge Anwendung finden müssen.Of course, the invention is not limited to the above in detail Forms of training shown and described are limited, but there are numerous Changes possible without deviating from the basic idea, a dust discharge behind dry filter systems, preferably for mining, so that the dust discharge device, e.g. screw conveyor or scraper belt conveyor, the dry one dusty material, fed to a sludge pump, into which under operation Activation of a guarantee liquid switch is only funded if a sufficiently high water pressure pending. Through this arrangement is the guarantee is given that the sludge feed pump does not run dry and thus a) is not destroyed and b) the dust inevitably due to this forced switching is discharged as a non-dusty, moist mass, with small hose lines Can be used and not large, rigid, unwieldy via wet screw conveyors Conveyor troughs must be used.
