Reinigungsvorrichtungen.Cleaning devices.

Patentiert im Deutschen Reiche vom 24. November 1911 ab.Patented in the German Empire on November 24, 1911.

Es sind bereits Vorrichtungen zum Reinigen von SchlaucMltern bekannt, bei denen die Innenwände der Schläuche durch in den Filter auf und ab bewegte Bürsten u. dgl. gereinigt werden. Ferner sind Vorrichtungen zum Reinigen von Trommelfiltern bekannt, bei denen die Filterfläche durch eine selbsttätige auf und ab bewegte Luftabsaugevorrichtung gereinigt wird. Außerdem sind Vorrichtungen bekannt, bei denen Luft aus den Filterschläuchen gesaugt wird, um die durch die Abklopfvorrichtung bewirkte Reinigung zu erleichtern. There are already devices for cleaning hose parents are known in which the The inner walls of the hoses are cleaned by brushes and the like moving up and down in the filter will. Furthermore, devices for cleaning drum filters are known in which the filter surface is cleaned by an automatic air suction device that moves up and down will. In addition, devices are known in which air from the filter bags is sucked to facilitate the cleaning effected by the knocking device.

Gegenstand vorliegender Erfindung ist eine Vorrichtung zur trockenen Reinigung staubhaltiger Gase oder Luft mit in einer Filterröhre sich auf und ab bewegbarer Staubabsaugevorrichtung. Das Neue der Erfindung besteht darin, daß die Staubfläche der zu reinigenden Filterröhre sich durch ihre eigene Spannkraft an die Saugöffnungen der durch einen Schlitten getragenen Staubsaugeringröhren schmiegt, wodurch eine gleichmäßige Reinigung des Filtertuches gewährleistet wird.The present invention relates to a device for dry cleaning of dust-laden Gas or air with a dust extraction device that can be moved up and down in a filter tube. The novelty of the invention is that the dust surface of the filter tube to be cleaned is through its own Tensioning force on the suction openings of the vacuum cleaner ring tubes carried by a carriage nestles, which ensures that the filter cloth is cleaned evenly.

Außerdem hat eine an der Filterröhrendecke angeordnete Klappe den Zweck, beim Versagen der Reinigungsvorrichtung die ungereinigten Gase oder Luft in die Gasabzugsrohrleitung gelangen zu lassen, um schädliche Einwirkungen auf die Vorrichtung zu verhüten. In addition, a flap arranged on the top of the filter tube serves to prevent failure the cleaning device, the uncleaned gases or air into the gas exhaust pipe to get to prevent harmful effects on the device.

Auf der Zeichnung ist der Filter und seine Reinigungsvorrichtung in einem Ausführungsbeispiel dargestellt, und zwar zeigen: In the drawing, the filter and its cleaning device is shown in an exemplary embodiment, namely show:

Fig. ι einen Höhenschnitt durch die Vorrichtung, Fig. Ι a vertical section through the device,

Fig. 2 einen Querschnitt in der Ebene I-I,Fig. 2 shows a cross section in the plane I-I,

Fig. 3 einen Querschnitt durch ein Saugrohr mit Filterwand undFig. 3 shows a cross section through a suction pipe with filter wall and

Fig. 4 einen Grundriß und Längsschnitt durch ein Saugrohr mit Filterwand.Fig. 4 is a plan and longitudinal section through a suction pipe with filter wall.

Die Vorrichtung besteht aus einer zylindrischen Röhre a, die aus Metall- und Stoffgewebe (ersteres liegt innen und dient zum Schutz des Stoffes) besteht, unten einen Blechboden hat und oben mit einer Sicherheitsglocke d verschlossen ist, und in welcher ein Röhrenschlitten in den Führungseisen e auf und ab bewegt wird, um durch die Saugringe c, das Verbindungsrohr f und den Schlauch i den an der Innenseite der Filterröhre α sich ansetzenden Staub während des Betriebes gleichmäßig abzusaugen. Der Röhrenscblitten wird durch den Wechselantrieb k und die obere Kettenrolle I bewegt, über die eine Kette m führt. Diese ist mit dem Haken η und letztere mit dem Röhrenschlitten fest verbunden.The device consists of a cylindrical tube a made of metal and fabric (the first is inside and serves to protect the fabric), has a sheet metal bottom at the bottom and is closed with a safety bell d at the top, and in which a tube slide in the guide iron e is moved up and down in order to evenly suck off the dust accumulating on the inside of the filter tube α through the suction rings c, the connecting pipe f and the hose i during operation. The tube cutter is moved by the change drive k and the upper chain roller I , over which a chain m leads. This is firmly connected to the hook η and the latter to the tube slide.

Die Saugringe c haben an ihrem Umfang, an den sich das Filtergewebe anschmiegt, eine rillenartige Vertiefung 0, in die in gewissen Abständen am Umfange des Saugringes c Saugöffnungen φ gebohrt sind, durch welche der Staub entweicht.The suction rings c have a groove-like depression 0 on their circumference, to which the filter fabric clings, into which suction openings φ are drilled at certain intervals on the circumference of the suction ring c , through which the dust escapes.

Die Sicherheitsglocke d hat den Zweck, im Falle, daß die Reinigungsvorrichtung versagt, wodurch sich die Gewebe der Filterröhre α verstopfen würden und so kein GasThe safety bell d has the purpose in the event that the cleaning device fails, whereby the fabric of the filter tube α would clog and so no gas
