FilterpatroneFilter cartridge

Die Neuerung betrifft eine Filterpatrone mit den Merkmalen des Oberbegriffs des Anspruchs 1.The innovation relates to a filter cartridge with the features of the preamble of claim 1.

Es sind Filterpatronen bekannt, die aus den beiden genannten Metal lgittern, einem aus gefalteten Papier oder dgl. bestehenden eigentlichen Filterkörper und zwei Kunststoffabschlüssen an den Filterenden bestehen. Wenn der Filterkörper nicht mehr brauchbar ist, wird die gesamte Filterpatrone weggeworfen. Ein Recyclen ist wegen der unterschiedlichen Stoffe nicht bzw. nur mit hohem Aufwand möglich.There are known filter cartridges that consist of the two metal grids mentioned, an actual filter body made of folded paper or similar and two plastic caps at the filter ends. When the filter body is no longer usable, the entire filter cartridge is thrown away. Recycling is not possible or only possible with great effort due to the different materials.

Der Neuerung liegt die Aufgabe zugrunde, Teile der Filterpatrone wieder zu verwenden und ein leichteres Recyclen des Rests zu ermöglichen. The innovation is based on the task of reusing parts of the filter cartridge and making it easier to recycle the rest.

Diese Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in claim 1.

Anhand der Zeichnung werden Ausführungsbeispiele der Neuerung näher erläutert.The drawing provides a more detailed explanation of the implementation of the innovation.

Es zeigen:Show it:

In Fig. 1 ist ein Schnitt durch eine neuerungsgemäße Filterpatrone gezeigt. Es ist in radialer Richtung gesehen nur die eine Hälfte der Filterpatrone gezeigt. Der Patronentyp der Fig. 1 wird meist in der gezeigten hängenden Form verwendet.Fig. 1 shows a section through a filter cartridge according to the innovation. Only one half of the filter cartridge is shown in the radial direction. The cartridge type in Fig. 1 is usually used in the hanging form shown.

Die Filterpatrone der Fig. 1 besteht aus einem zylinderförmigen Patronengehäuse, einem Filterkörper und zwei Halterungsteilen an den Enden. Das Patronengehäuse enthält zwei zylinderförmige, konsentrisch zueinander liegende Metallgitter 1 und 2. Am oberen Ende ist ein Haltering 3 vorgesehen, der gleichzeitig den Innenraum 4 des Zylinders und den daran anschließenden Raum des Patronenfilters gegenüber dem Raum 5 des Patronenfilters abdichtet (Dichtung 6). Man muß sich dazu vorstellen, daß der Außenraum 5 und der anThe filter cartridge of Fig. 1 consists of a cylindrical cartridge housing, a filter body and two mounting parts at the ends. The cartridge housing contains two cylindrical metal grids 1 and 2 that are concentric with each other. A mounting ring 3 is provided at the upper end, which simultaneously seals the interior 4 of the cylinder and the adjacent space of the cartridge filter from the space 5 of the cartridge filter (seal 6). It must be imagined that the exterior space 5 and the

den Innenraum 4 anschlie3ende Raum von einem Patronenfiltergehäuse umgeben ist. Der Innenraum des Gehäuses ist durch das Filter und ein Teil 7 in zwei Räume unterteilt. Dem Außenraum 5 wird zu reinigendes Rohmedium z.B. Gas oder eine Flüssigkeit zugeführt, dem an den Innenraum 4 anschließenden Raum wird Reinmedium entnommen Zwischen den Metallgittern 1 und 2 ist ein Filterkörper 17 angeordnet, der aus gefaltetem Papier oder dgl. &thgr; und Kunststoffabschlüssen 9 und 10 besteht (sh. Fig. 2). In dem Filterpatronengehäuse 1, 2 wird der Filterkörper 17 zwischen dem Haltering 3 und einer Halterungsplatte 11 gehalten. Der Innenraum 4 ist auch durch eine Platte 12 gegenüber dem Raum 5 abgedichtet. Der Halterungsplatte 11 steht eine weitere Platte 13 gegenüber. Diese beiden Platten können entgegen den Kräften von Federn 14 aneinander angenähert werden. Am Umfang weist die zweite Platte 13 drei unsymmetrisch angeordnete Zapfen 15 auf, und in einer Verlängerung 16 des äusseren Metallgitters sind korrespondierende öffnungen eingelassen .the space adjoining the interior 4 is surrounded by a cartridge filter housing. The interior of the housing is divided into two spaces by the filter and a part 7. The raw medium to be cleaned, e.g. gas or a liquid, is fed to the exterior 5, and the clean medium is taken from the space adjoining the interior 4. A filter body 17 is arranged between the metal grids 1 and 2, which consists of folded paper or the like and plastic ends 9 and 10 (see Fig. 2). In the filter cartridge housing 1, 2, the filter body 17 is held between the retaining ring 3 and a mounting plate 11. The interior 4 is also sealed off from the space 5 by a plate 12. Another plate 13 is opposite the mounting plate 11. These two plates can be brought closer together against the forces of springs 14. The second plate 13 has three asymmetrically arranged pins 15 on its circumference, and corresponding openings are set into an extension 16 of the outer metal grid.

Indem man zuerst den Zapfen 15 so weit wie möglich durch die entsprechende öffnung schiebt, und die Platten 11 und 13 aneinander annähert, wird es möglich, die beiden anderen Zapfen in entsprechenden öffnungen in der Verlängerung 16 einzuführen. DurchBy first pushing the pin 15 as far as possible through the corresponding opening and bringing the plates 11 and 13 closer together, it is possible to insert the other two pins into corresponding openings in the extension 16. By

Kerben 18 in den Zapfen ist das Plattenpaar 11 und 13 gegen Herausfallen gesichert.The pair of plates 11 and 13 are secured against falling out by notches 18 in the tenons.

Ein Griff 19 dient dem leichteren Transport des Filters, gleichzeitig wird durch sein Verdrehen eine Ringmutter verdreht und dadurch die Platten 11 und 13 aneinander angenähert bzw. voneinander entfernt. Bei Filterwechsel werden hier nur die Platten 11 und abgenommen, der Filterkörper 17 ausgetauscht und dann der neue Filterkörper eingespannt.A handle 19 is used to facilitate transport of the filter, at the same time by turning it a ring nut is turned and thereby the plates 11 and 13 are brought closer together or further apart. When changing the filter, only the plates 11 and 13 are removed, the filter body 17 is replaced and then the new filter body is clamped in.

Die Filterpatrone der Fig. 3a zeigt eine mit den Metallgittern 1 und 2 verbundene Abschlußplatte 20 am unteren Ende. Auf die Trennwand 7 des Patronenfiltergehäuses ist hier ein Halteteil aufgeschraubt, das einen mittels eines Hebels 23 verdrehbaren Gewindebolzen 22 aufweist. Mit drei solchen Bolzen wird ein Haltering 24 für den Filterkörper 17 eingespannt und der Innenraum gegenüber dem Außenraum abgedichtet (Dichtung 25). Durch Entspannen der Einspannung des Rings 24 durch geringe Verdrehung der Gewindebolzen 22 und seitliches Wegklappen des Halteteils 21 in Pfeilrichtung vom Anschlag 26 weg ist in kurzer Zeit der Haltering 24 abnehmbar und der Filterkörper kann ausgewechselt werden.The filter cartridge in Fig. 3a shows an end plate 20 connected to the metal grids 1 and 2 at the lower end. A holding part is screwed onto the partition wall 7 of the cartridge filter housing, which has a threaded bolt 22 that can be rotated using a lever 23. A holding ring 24 for the filter body 17 is clamped in place using three such bolts and the interior is sealed from the exterior (seal 25). By relaxing the clamping of the ring 24 by slightly turning the threaded bolts 22 and folding the holding part 21 sideways in the direction of the arrow away from the stop 26, the holding ring 24 can be removed in a short time and the filter body can be replaced.
