Abstract

Flames and or dust particles are prevented from penetrating by a layered protective mesh, obviating risk of explosion, in the filter in a pure gas duct or elsewhere in a mine (as in 2842908). The flame-protective mesh (2) is fitted with a temp sensor (5), pref. in the pure gas (3) duct area. This releases extinguishing media, pref. via a valve (7). This responds to a prescribed temp to release a foam extinguisher or water connection (6) for cooling and/or quenching action.

Description

Beschreibung und Erläuterung zur Zusatz-Patent- und -Hilfsgebrauchsmusteranmeldung 'Bergbau-Flammschutzfilter mit Temperaturlöscheinrichtung' Zusatz zu P 28 42 908.5 In der Hauptanmeldung wird ein Filter beschrieben, der z. B. im Reingaskanal ein mehrlagiges Flammschutzgewebe besitzt, bestehend z. B. aus Wetterlampenkorbdrahtgeflecht, wodurch gewährleistet ist, daß die Flammen und/oder Staubteilchen nicht durchschlagen, so daß die Gefahr einer Schlag- und/oder Kohlenstaubexplosion weitgehendst vermieden wird.Description and explanation of additional patent and utility model applications 'Mining flame protection filter with temperature extinguishing device' Addition to P 28 42 908.5 In the parent application, a filter is described which z. B. in the clean gas duct has multi-layer flame retardant fabric, consisting, for. B. from weather lamp basket wire mesh, which ensures that the flames and / or dust particles do not penetrate, so that the risk of an impact and / or coal dust explosion largely avoided will.

Erfindungsgemäß soll diese Gefahr weiter eingedämmt werden, indem die Mehrlage, vorzugsweise Drahtgewebeschicht, mit einem Temperaturfühler versehen wird, der bei vorgegebener Temperatur von z. B. 150 OC anspricht und einen Schaumlöscher oder einen Wasseranschluß freigibt, und das Filter sofort unter entsprechende Kühl- und/oder Löschmittel gesetzt wird.According to the invention, this risk is to be further contained by the multilayer, preferably wire mesh layer, is provided with a temperature sensor is, which at a given temperature of z. B. 150 OC responds and a foam extinguisher or a water connection releases, and the filter immediately under appropriate cooling and / or extinguishing agent is set.

In der beiliegenden Zeichnung ist die erfindungsgemäße Ausführung dargestellt; mit 1 das Rohqas mit 2 die Filterelemente mit 3 das Reingas mit 4 mehrlagige Drahtnetzanordnung oder feuerfeste Gewebeanordnung mit 5 der Temperaturfühler mit 6 ein Schaumlöscher oder ein Wasseranschluß mit 7 das auszulösende Ventil, das über Temperaturfühler geöffnet wird Zusatz-Patent- und -Hilfsgebrauchsmusteranspruch LeerseiteThe embodiment according to the invention is shown in the accompanying drawing shown; with 1 the raw gas with 2 the filter elements with 3 the clean gas with 4 multilayer Wire mesh assembly or fireproof fabric assembly with 5 of the temperature sensors with 6 a foam extinguisher or a water connection with 7 the valve to be triggered, which over Temperature sensor opened is additional patent and utility model claim Blank page
