Abstract

A dust filter for tunnel driving and gallery driving is intended for fitting to cutting machinery. The surface of the filter which faces towards the roof of the tunnel comprises a dirty gas duct and a filtered gas duct; these taper in opposite directions, i.e. the dirty gas duct becomes narrower away from the inlet and the clean gas duct widens out towards the outlet. Pref. the compressed air storage pipe and compressed air ejector nozzle are mounted in the clean gas duct, the nozzle being oriented so that a compressed air pulse causes compression in the clean gas collecting chamber. Pref. also, the filter bags or pockets are removable together with the inspection doors. Compact construction, capability of operating at high atmospheric humidity and with humid dust, good access for changing and cleaning the filters and other maintenance work is provided. The tapered arrangement of the ducts ensures optimum utilisation of the space available for a given flow condition.

Beschreibung und Erläuterung zurDescription and explanation of the

Patentanmeldung 'Filter für den Strecken- und Tunnelvortrieb' Im Bergbau und Tunnelbau werden vielfach Trockenfilter zur Absaugung an Teil- und Vollschnittmaschinen transportabel mitgezogen.Patent application 'Filters for road and tunnel driving' in mining and tunnel construction are often dry filters for extraction on partial and full-face machines transportable.

Dazu ist erforderlich, daß diese Filter 1) sehr klein bauen, 2) auch mit relativer, hoher Luftfeuchte und nassem Staub betriebsbereit bleiben müssen und 3) eine für die engen Grubenverhältnisse gut zugängliche Filterein- und ausbaumöglichkeit besitzen sowie eine gut zugängliche Wartungsmöglichkeit erlauben.This requires that these filters 1) build very small, 2) also must remain operational with relative high humidity and wet dust and 3) an easily accessible filter installation and removal option for the narrow pit conditions and allow an easily accessible maintenance option.

Diese Erfordernisse werden erfindungsgemäß in der Ausführung entsprechend beiliegender Zeichnung gewährleistet.According to the invention, these requirements are implemented accordingly enclosed drawing guaranteed.

In der beiliegenden Zeichnung ist dargestellt: Abb. A) die Draufsicht des Filtergerätes.The attached drawing shows: Fig. A) the top view of the filter device.

Mit 1) der Rohgaseintritt, mit 2) der Rohgaskanal, mit 3) der Reingasaustritt, mit 4) der Reingaskanal.With 1) the raw gas inlet, with 2) the raw gas duct, with 3) the clean gas outlet, with 4) the clean gas duct.

Durch diese Anordnung des Roh- und Reingaskanals oberhalb des Filterraums in der Form, daß Roh- und Reingaskanal sich gegenläufig verengen, ist eine sinnvolle, größtmögliche Rauaausnutzung für das An- und Ausströmen gewährleistet.This arrangement of the raw and clean gas ducts above the filter space in the form that the raw and clean gas ducts constrict in opposite directions is a sensible one, Maximum possible use of the space for inflow and outflow guaranteed.

In der Abb. B ist dargestellt: mit 5) die seitlich aus- und einbaubare Filtertasche.In Fig. B it is shown: with 5) the one that can be removed and installed at the side Filter bag.

Mit 6) der Staubsammeiraum, mit 7) der Reingaskanalsammelraum, mit 8) das Druckluftspeicherrohr, mit 9) das Druckluftstoßventil, das über Zeitrelais erfordernisgerecht eingeschaltet werden kann, mit 10) die seitlich angebrachte Inspektions- oder Montagetür, die vorzugsweise an beiden Seitenflächen angeordnet ist.With 6) the dust collection room, with 7) the clean gas duct collection room, with 8) the compressed air storage pipe, with 9) the compressed air push valve, which via time relay can be switched on as required, with 10) the side-mounted inspection or assembly door, which is preferably arranged on both side surfaces.

Durch diese erfindungsgemäße Ausführung des seitlichen Anbaus der Luftstoßreinigungseinrichtung ist in einfachster Weise die Uberpräfung des Systems im Rohgaskanal mit Druckluft sp ei cherrohr und Druckluft st oßvent il en durch öffnen der Inspektionstüren gewährleistet. Weiterhin können durch die Inspektionstüren die Filtertaschen aus- und eingebaut werden und es kann trotz der beengten Grubenräuje die Revision bzgl. Undichtigkeiten von Filtertaschen für den Bergmann gut zugänglich und unter In-Augens che in-Nahme der gesamten Aufhänge einrichtung der Filtertaschen durchgeführt werden.With this inventive design of the lateral cultivation Air blast cleaning device is the simplest way to check the system in the raw gas duct with compressed air storage tube and compressed air flow valves opening of the inspection doors guaranteed. You can also go through the inspection doors the filter bags can be removed and installed and it can be done despite the cramped pit spaces the revision regarding leaks in filter bags easily accessible to the miner and taking into account the entire hanging device for the filter bags be performed.

Die Taschenreinigung erfolgt durch den Druckstoß, der die im Reingassammelraum befindliche Luft verdichtet und so eine optimale Abreinigung bringt.The bag is cleaned by the pressure surge that occurs in the clean gas collection chamber compresses the air that is present and thus provides optimal cleaning.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, die Deckelfläche des Filters so auszubilden, daß sie aus einem Roh- und Reingaskanal besteht, der gegenläufig sich verengt bzw.Of course, the invention is not limited to the above in detail The forms of training shown are limited, but there are numerous changes possible, but without deviating from the basic idea, the cover surface of the filter to be trained so that it consists of a raw and clean gas duct that runs in opposite directions narrows or

erweitert und die Filtertaschen seitlich herausnehmbar sind und die Anordnung der Druckstoßreinigungseinrichtung so angeordnet ist, daß sie vom Reingaskanal ausgehend über die Düsenwirkung eine Verdichtung der Luft im Reingassammelraum bewirkt und dadurch die Filtertaschen gereinigt werden. expanded and the filter bags can be removed from the side and the Arrangement of the surge cleaning device is arranged so that it is from the clean gas duct Based on the nozzle effect, the air in the clean gas collection chamber is compressed and thereby the filter bags are cleaned.
