Title (EN) DUST FILTER
(FR) FILTRE A POUSSIERE
(DE) STAUBFILTER
Abstract:
(EN) The present invention relates to a dust filter such as a hose filter which is mainly intended for cleaning primary air containing dust or the like. The purpose of this invention is to simplify the cleaning process of the filter members and to reduce the design complexity for supplying pressurised air thereto. To this end, the space above the cleaning air nozzles (11) is made in the shape of a pressure chamber (13), which eliminates the need for the fittings and control devices used in the present techniques.
(FR) L'invention concerne un filtre à poussière, par exemple un filtre à manche, notamment pour nettoyer l'air primaire chargé de poussière ou similaire. L'invention vise à simplifier le nettoyage des éléments de filtre et à réduire la complexité de conception pour mettre à disposition l'air comprimé. A cet effet, l'espace se trouvant au-dessus des buses d'air de nettoyage (11) est conçu sous forme de chambre de pression (13) de sorte qu'il n'est plus nécessaire d'utiliser les robinetteries et appareils de commande indispensables jusqu'à présent.
(DE) Die Erfindung betrifft einen Staubfilter, wie z.B. einen Schlauchfilter, insbesondere zur Reinigung staubbeladener Förderluft u. dgl. Ihr lag die Augabe zugrunde, die Abreinigung der Filterelemente zu vereinfachen und den konstruktiven Aufwand zur Bereitstellung der Druckluft hierzu zu reduzieren. Die Aufgabe wird dadurch gelöst, dass der oberhalb der Spülluftdüsen (11) befindliche Raum als Druckraum (13) ausgebildet ist, so dass auf bisher notwendige Armaturen und Steuergeräte verzichtet werden kann.
