Description

Filtermantel für Zellenfilter-Saugtrommeln.Filter jacket for cell filter suction drums.

Es sind Filtertrommelmäntel bekannt,- die aus einem gelochten Blechzylinder, über den ein oder mehrere Lagen von Filtergaze oder -stoff gespannt sind, bestehen. Diese Mäntel werden in der Weise auf ihrer Saugtrommel befestigt, daß ihre einzelnen Teile nacheinander auf die Trommel aufgebracht und mit ihr verbunden werden. Eine auf solche Weise überzogene Trommel läßt meistens hinsichtlich Dichthalten viel zu wünschen übrig. There are known filter drum jackets, - made of a perforated sheet metal cylinder, Over which one or more layers of filter gauze or fabric are stretched exist. These jackets are attached to their suction drum in such a way that their individual Parts are applied one after the other to the drum and connected to it. One drum coated in this way usually leaves a lot in terms of sealing to be desired.

Der Filtermantel nach der Erfindung kann leicht ausgewechselt und immer wieder dicht auf seiner Trommel befestigt werden, indem er erfindungsgemäß als Ganzes, d. h. der Lochzylinder und alle seine Filtertücher außerhalb der Trommel aufeinander befestigt und dann als Ganzes auf die Trommel aufgeschoben und luftdicht mit ihr verbunden wird. The filter jacket according to the invention can be easily replaced and always be tightly fastened on his drum by inventing as a whole, d. H. the perforated cylinder and all of its filter cloths outside the drum attached to each other and then pushed onto the drum as a whole and airtight is connected to her.

Die Zeichnung stellt den neuen Filtermantel in Verbindung mit einer Filtertrommel dar, und zwar zeigen Abb. 1 einen Schnitt des Filtermantels samt der Trommel, Abb. 2 einen Teil des Schnittes nach Abb. I im größeren Maßstabe und Abb. 3 eine Vorderansicht mit teilweisem Querschnitt des Mantels samt der Trommel. The drawing shows the new filter jacket in connection with a The filter drum, namely Fig. 1 shows a section of the filter jacket together with the Drum, Fig. 2 a part of the section according to Fig. I on a larger scale and Fig. 3 is a front view with partial cross-section of the shell including the drum.

Der neue Filtermantel besteht, von innen nach außen aufgezählt, aus einem vorteilhaft bienenwabenartig gelochten Blechzylinder f, einem Drahtgewebeschlauch g und einem Überzug h aus Seiden-, Textil- o.dgl. Gesiebe, wobei die Teiles, g, h ebenso lang wie die Zellentrommel sind. Die Wände i der Löcher k des gelochten Zylinders sind in bekannter Weise außen dachförmig gestaltet, damit das Vakuum überall mit gleicher Stärke wirken kann. Der endlose Drahtschlauch g wird unter Verwendung eines Ziehzeugs auf den Lochzylinder t aufgezogen und an seinen Stirnenden mit diesem dicht verlötet sowie hier gegebenenfalls noch mit Zellon 0. dgl. glatt verstrichen, um eine vollkommene Abdichtungfides Mantels mit der Trommel zu erreichen. Der Überzugh aus Seide o. dgl., der auf dem Drahtschlauch g aufliegt, hat entweder dieselbe Länge wie dieser und wird seitlich mittels zusammengenähten Wachstuch- oder Gummistreifens l festgehalten, oder er ist länger und wird an den Stirnrändern b der Trommel befestigt.The new filter jacket consists of, counted from the inside out an advantageously honeycomb-like perforated sheet metal cylinder f, a wire mesh hose g and a cover h made of silk, textile or the like. Sieves, where the part, g, h are as long as the cell drum. The walls i of the holes k of the perforated Cylinders are designed in a known manner on the outside roof-shaped, so that the vacuum everywhere can act with equal strength. The endless wire tube g is used a pulling tool drawn onto the perforated cylinder t and at its front ends with this tightly soldered and, if necessary, smoothed with Zellon 0. to achieve a perfect seal between the shell and the drum. The cover Made of silk or the like, which rests on the wire tube g, either has the same length like this one and is attached to the side by means of sewn together oilcloth or rubber strips l held, or it is longer and is attached to the end edges b of the drum.

Der neue Filtermantel wird für sich fertiggestellt und nun als Ganzes mit der mit innerem Vakuum arbeitenden sowie nach den Pfeilen, B sich entwässernden und entlüftenden Zellentrommel a verbunden. Diese hat an den Stirnseiten je einen ringsherum laufenden Rand b, der die Stirnwände für die Saugzellen c oben abschließt. Je nach der Arbeitsbreite der Trommel können in sie ein oder mehrere Ringe d eingegossen sein. Diese Ringe d, die Ränder b und die Zellenwände e, deren Oberflächen in einer genauen zylindrischen Fläche liegen, bilden die Auflage für den neuen Filtermantel. The new filter jacket will be completed on its own and now as a whole with the one working with an internal vacuum as well as draining itself according to the arrows, B and venting cell drum a connected. This has one on each end all around running edge b, which closes the end walls for the suction cells c above. Depending on the working width of the drum, one or more rings d can be cast into it be. These rings d, the edges b and the cell walls e, their surfaces in a exact cylindrical surface, form the support for the new filter jacket.

Der neue Filtermantel hat den Vorteil, daß es beim Auswechseln kürzere Stillstände im Betriebe gibt und man für eine einzige Zellensaugtrommel mehrere verschieden wirkende, auswechselbare Filtermäntel vorrätig haben kann. The new filter jacket has the advantage that it is shorter when it is replaced There are downtimes in the company and you have several for a single cell suction drum can have different acting, replaceable filter jackets in stock.
