Abstract

Filter material which is required for dry types of dust collectors in underground mines are made of mineral fibre mats or tissues which have been coated with metal. This adds to the refractory properties of the material an electric conductivity which is demanded by the Mines Inspectorable to ensure adequate safety against the accumulation of electrostatic charges.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

'Elektrisch leitfähiges, feuerfestes Staubfiltermaterial' Im Bergbau benötigt man vielfach TrockenentstauberO Diese Trockenentstauber sind als Tuchfilterentstauber ausgebildet.'Electrically conductive, fireproof dust filter material' In mining Dry dust extractors are often required O These dry dust extractors are used as cloth filter dust extractors educated.

Die Bergbehörde verlangt aufgrund der notwendigen Sicherheit, daß die Staubfiltertücher elektrisch leitfähig sind.Due to the necessary security, the mining authority requires that the dust filter cloths are electrically conductive.

Bei feuerfestem Filtermaterial, z.B. Mineralfasern, ist die Leitfähigkeit der geforderten Höhe nicht gewährleistet.In the case of fireproof filter material, e.g. mineral fibers, the conductivity is the required amount is not guaranteed.

Aus diesem Grunde wird erfindungsgemäß vorgeschlagen, Mineralfasern und/oder das Gewebe metallisch zu legieren.For this reason, the invention proposes mineral fibers and / or to alloy the fabric metallic.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, zur Verbesserung der Leitfähigkeit feuerfeste Mineralfasern oder Mineralgewebe mit Metall zu legieren.Of course, the invention is not limited to the above in detail The forms of training described are limited, but there are numerous changes possible without, however, from the basic idea to deviate for improvement the conductivity of alloying refractory mineral fibers or mineral fabrics with metal.
