Description

Die Erfindung betrifft einen Filter, bei dem die Filterflächen als konzentrische Zylinder ausgebildet sind, die stirnseitig abwechselnd durch ringförmige Filterflächen miteinander verbunden sind. Die als Taschenfilter bekannten Filter dieser Art enthalten als Filterflächen Gewebe. The invention relates to a filter in which the filter surfaces as concentric cylinders are formed, the end face alternately by annular Filter surfaces are connected to each other. The filters known as pocket filters of this type contain tissue as filter surfaces.

Die Erfindung hat den Zweck, die verhältnismäßig wertvollen Gewebefilter dieser Bauart durch Papierfilter zu ersetzen, um sie zur Feinstreinigung von Luft oder Gasen, vorzugsweise für kleinere Luftmengen, wie sie z. B. als Verbrennungsluft für die Motoren von Kraftfahrzeugen benötigt werden, benutzen zu können. The invention has the purpose of making the relatively valuable fabric filters Replace this design with paper filters in order to fine-tune the air or gases, preferably for smaller amounts of air, such as those used in e.g. B. as combustion air are required for the engines of motor vehicles to be able to use.

Dieses Ziel wird auf technisch einfache Weise erreicht, indem gemäß der Erfindung die gesamten Filterflächen in einem Stück aus Papiermasse gegossen werden. Hierdurch erzielt man einen Filtereinsatz bzw. eine Filterpatrone von sehr gedrängter Bauart. Bei senkrechter Anordnung des Filters und Durchtritt der zu reinigenden Luft von oben nach unten wird das Filter vorteilhaft durch ein grobes Sieb unterstützt, damit es nicht unter Einfluß der Druckdifferenz durchgebogen und eventuell zerrissen werden kann. Soweit es sich als notwendig erweisen sollte, können auf der Saugseite, um zu verhindern, daß unter dem Einfluß der Druckdifferenz zwischen Druck- und Saugseite die Filterpapierzylinder zusammengedrückt werden, Drahtgewebezylinder zwischen den Papierzylindern angeordnet werden. This goal is achieved in a technically simple manner by according to the invention cast the entire filter surfaces in one piece of paper pulp will. This results in a filter insert or a filter cartridge of very high compact design. With vertical arrangement of the filter and passage of the filter to be cleaned Air from top to bottom, the filter is advantageously supported by a coarse sieve, so that it does not sag and possibly tear under the influence of the pressure difference can be. If it should prove necessary, on the suction side, to prevent being under the influence of the pressure difference between pressure and suction side the filter paper cylinders are squeezed together, wire mesh cylinders between the Paper cylinders are arranged.

In der Zeichnung ist eine ausführungsform des Filters in Fig. 1 im Längs- und in Fig. 2 im Querschnitt dargestellt. Darin bedeutet 1 das Gehäuse, 2 den Papierfiltereinsatz und 3 das abstützende Siebgewebe. In the drawing, an embodiment of the filter in Fig. 1 is in Shown longitudinally and in cross section in FIG. 2. 1 means the housing, 2 the paper filter element and 3 the supporting screen mesh.
