Description

Filter für flüssige Kohlenwasserstoffe und dergl.Filters for liquid hydrocarbons and the like.

Die Neuerung betrifft ein Filter für flüssige Kohlenwasserstoffe und dergl., bestehend aus einem Vorfilter und einem diesem in der Strömungarichtung des Filtergutes nachgeschalteten Feinfilter, die beide in einem gemeinsamen Gehäuse konzentrisch ineinander angeordnet sind. Die mit dem Gegenstand der Neuerung zu lösende Aufgabe wird in der Schaffung eines Kombinationsfilters gesehen, das konstruktiv einfach ist, ferner ein unabhängiges Reinigen der beiden Filtereinsätze ermöglicht.The innovation concerns a filter for liquid hydrocarbons and The like., Consisting of a pre-filter and this one in the flow direction the downstream fine filter, both in a common housing are arranged concentrically one inside the other. Those with the subject of the innovation too The solution to the problem is seen in the creation of a combination filter that is constructive is simple, and also enables the two filter inserts to be cleaned independently.

Bei den bekannten Filtern obiger Gattung loßt sich das Vorfilter nicht unabhängig vom Feinfilter ausbauen und reinigen, sondern es ist hierzu jeweils auch das Feinfilter auszubauen. Dadurch wird das Ausbauen und Reinigen umständlich. Diese Nachteile der bekannten Filter sind konstruktionsbedingt. So ist das Vorfilter bei verschiedenen Konstruktionen an mit der Filterwelle mittel-oder unmittelbar verbundenen ringförmigen Stützen befestigt. In anderen Fällen wiederstutzen sich Vor-und Feinfilter an beiden Enden gegen g meinsam Platten ab, die mit der Filterwelle in mittel-oder unmittelbarer Verbindung stehen. Diese Konstruktion hat sich, wie bereits gesagt, als umständlich erwiesen. Die erahnten Mängel werden gemäß der Neuerung im wesentlichen dadurch behoben, daß die beiden Filtereinsätze unabhängig voneinander ein-und ausbaubar sind, indem das Vorfilter einenends im Boden des Filtergehäuses, anderenends im Gehäusedeckel dichtend gehalten, und das Feinfilter einenends gegen eine Nabe des Filtergehäuses, anderenends gegen die Welle des Filters abgedichtet ist, welche in bekannter Weise durch das Gehäuse hindurchgeführt und mit Kanälen zum Abführen des Filtrats versehen ist, Auf diese Weise ergeben sich den bekannten Filterkonstruktionen gegenüber nicht zu unterschätzende Vorteile. So sind nach Öffnen des Gehäuseaeckels beide Filtereinsätze frei zugänglich. Das Vorfilter lagert nach Abnahme des Gehäusedeckels nur noch im Boden des Filtergehäuses 2 und umgibt das Feinfilter wie in Mantel. Das Feinfilter wiederum lagert unmittelbar auf der Welle und bildet mit dem Gehäusedeckel eine abnehmbare Baugruppe. Durch die unmittelbare Lagerung des Vorfilter im Gehäuseboden, ferner die uirekte Lagerung des Feinfilters auf der Filterwelle können die bei den bekannten Filtern notwendigen zusätzlichen Lagerringe wegfallen, so daß sich auch in baulicher Hinsicht eine Verbesserung und Vereinfachung ergibt.In the known filters of the above type, the prefilter cannot be removed and cleaned independently of the fine filter, but the fine filter must also be removed for this purpose. This makes dismantling and cleaning cumbersome. These disadvantages of the known filters are due to their design. Thus, in various constructions, the prefilter is attached to annular supports that are indirectly or directly connected to the filter shaft. In other cases, pre-filters and fine filters are cut off at both ends against common plates that are in medium or direct connection with the filter shaft. As already mentioned, this construction has proven to be cumbersome. According to the innovation, the anticipated deficiencies are essentially remedied by the fact that the two filter inserts can be installed and removed independently of one another, in that the prefilter is held in a sealing manner at one end in the bottom of the filter housing and at the other end in the housing cover, and the fine filter is sealed at one end against a hub of the filter housing and at the other end against the shaft of the filter, which is passed through the housing in a known manner and is provided with channels for discharging the filtrate. In this way, advantages not to be underestimated result compared to the known filter constructions. Both filter inserts are freely accessible after opening the housing cover. After removing the housing cover, the prefilter is only stored in the bottom of the filter housing 2 and surrounds the fine filter as if in a jacket. The fine filter, in turn, rests directly on the shaft and forms a removable assembly with the housing cover. Due to the direct mounting of the pre-filter in the bottom of the housing and the direct mounting of the fine filter on the filter shaft, the additional bearing rings required in the known filters can be omitted, so that there is also an improvement and simplification from a structural point of view.

Gemäß der Neuerung ist weiterhin für jedes Filter ein Absetzraum in dem gemeinsamen Gehäusedeckel vorgesehen. Die beiden Absetzräume sind konzentrisch ineinanderliegend angeordnet. Außerdem hat jeaer der beiden Absetzräume seine eigene Ablaßschraube, wodurch erreicht wird, daß aer abgefilterte Schmutz jedes Filters völlig unabhängig vom anderen Filter entfernt werden kann. According to the innovation, there is still a settling room for each filter provided in the common housing cover. The two settling rooms are concentric arranged one inside the other. In addition, each of the two settling rooms has its own Drain plug, whereby it is achieved that the filtered dirt of each filter can be removed completely independently of the other filter.

Einzelheiten der Neuerung sind aus der nachstehenden Beschreibung und aus der Zeichnung ersichtlich, die ein Ausführungsbeispiel des Gegenstandes der Neuerung im Längsschnitt veranschaulicht.Details of the innovation are from the description below and can be seen from the drawing, which shows an embodiment of the object the innovation illustrated in a longitudinal section.

In der Nabe 1 des einseitig offenen Filtergehäuses 2 ist eine Welle 3 gelagert, die beispielsweise durch Einschrauben in die Nabe gesichert ist. Auf die Welle aufgesteckt ist ein Feinfiltereinsatz 4, der aus einer Vielzahl von übereinander liegenden Papierringen gebildet sein kann und mittels der beiden Dichtungsringe 5 und 6 gegen die Nabe 1 und die Welle 3 abgedichtet ist. Gegen axiale : Verschieben gesichert wird der Filtereinsatz durch den in die Welle eingeschlaenen Stift 7 und die Unterlegscheibe 8. In the hub 1 of the filter housing 2, which is open on one side, there is a shaft 3 stored, which is secured for example by screwing into the hub. on Attached to the shaft is a fine filter element 4, which consists of a large number of one above the other lying paper rings can be formed and by means of the two sealing rings 5 and 6 is sealed against the hub 1 and the shaft 3. Against axial: move The filter insert is secured by the pin 7 and inserted into the shaft the washer 8.

Unabhängig vom Feinfilter 4 ist in das Gehäuse 2 ein Vorfilter eingebaut das zweckmäßig aus einer Anzahl von Filzringen 9 und einem zylindrischen Siebmantel 10 besteht. Um dem Vorfilter im Gehäuse 2 einen Halt zu eben, viird es an beiden Enden durch je einen Ring 11 bzw. 12 begrenzt, wovon der letztere mit dem Siebmantel 10 fest verbunden ist, während der Ring 11 lose eingesetzt wird und sich mit seiner Auswölbung 13 gegen einen Sprengring 14 anlegt, der seine Führung in der Rundsicke 15 des Siebmantels 10 hat.A prefilter is built into the housing 2 independently of the fine filter 4 this expediently from a number of felt rings 9 and a cylindrical screen jacket 10 consists. In order to hold the prefilter in the housing 2, it should be attached to both The ends are bounded by a ring 11 or 12, the latter with the sieve casing 10 is firmly connected, while the ring 11 is inserted loosely and with his Bulge 13 applies against a snap ring 14, which its leadership in the round bead 15 of the screen jacket 10 has.

Die Teile 9 bis 15 des Vorfilters einschließlich der Dichtung 16 können vor ihrem Einbau in das Filtergehäuse 2 zusammengesteckt und dann gemeinsam in das Gehäuse 2 eingesetzt werden. Verschlossen 0 r- wird das Filtergehäuse 2 durch einen Deckel17, der das freie Ende des Gehäuses dicht umschließt, während eine weitere Dichtung 18 zwischen Gehäusedeckel 17 und Vorfilter 9, 10 vorgesehen ist, die sich in den Ring 12 einlegt und durch den Gehäusedeckel amgepreßt wird. Mittels der auf das Ende der Welle 3 aufschraubbaren Rundmutter 19 wird der Gehäusedeckel 17 festgestellt, wobei im Bedarfsfalle ein Nachspannen möglich ist.The parts 9 to 15 of the prefilter including the seal 16 can be plugged together before they are installed in the filter housing 2 and then used together in the housing 2. Locked 0 r- the filter housing 2 is provided by a cover 17 which tightly encloses the free end of the housing, while a further seal 18 is provided between the housing cover 17 and the prefilter 9, 10, which is inserted into the ring 12 and is pressed on by the housing cover. By means of the round nut 19 which can be screwed onto the end of the shaft 3, the housing cover 17 is fixed, with retightening being possible if necessary.

Das Kombinationsfilter steht über den Zuflußstutzen 20 mit dem der Einfachheit halber auf der Zeichnung nicht dargestellten Kraftstoffbehälter in Verbindung. Das Filtergut passiert zuerst das Vorfilter 9,10, das die gröberen Verunreinigungen absondert, üie sich in den freien Raum 21 zwischen Filteròehäuse und Vorfilter absetzen. Das vorgefilberte Gut muß dann den Siebmantel 10 durchdringen, uer weitere Verunreinigungen ausscheidet, ehe es durch das Feinfilter 4 gelangt. Durch das Feinfilter ausgeschiedene Verunreinigungen setzen sich in den Raum 22 ab. Das Filtrat dringt in die Bohrungen 23 der Welle 3 ein und fließt über den Abflußstutzen 24 beispielsweise einer Brennstoffpumpe zu, die ebenfalls auf der eichnung nicht dargestellt ist. Der Abflußstutzen 24. wiederum ist mittels der beiden Dichtringe 25 und 26 nach außen abgedichtet und wird mit Hilfe der Rundmutter 27 festgezogen. Für Z> 42 jeden der beiden Absetzräume 21 und 22 sind gesonderte Ablaßschraube 28 bzw. 29 vorgesehen, durch die das Filtergehäuse. gereinigt bzw. entleert werden kann.The combination filter is connected to the fuel tank, which is not shown in the drawing for the sake of simplicity, via the inflow connection 20. The filter material first passes the pre-filter 9, 10, which separates the coarser impurities, which settle in the free space 21 between the filter housing and the pre-filter. The pre-filtered material must then penetrate the sieve casing 10, before it passes through the fine filter 4, further impurities are eliminated. Impurities separated by the fine filter settle in the space 22. The filtrate penetrates into the bores 23 of the shaft 3 and flows via the drain connection 24 to, for example, a fuel pump, which is also not shown in the drawing. The drain connection 24 is in turn outwardly by means of the two sealing rings 25 and 26 sealed and is tightened with the help of the round nut 27. For Z> 42 each of the two settling spaces 21 and 22 are provided with separate drain plugs 28 and 29 through which the filter housing. can be cleaned or emptied.

Die aufgezeigte Konstruktion hat den Vorteil, daß das Vorfilter 9, 10, insbesondere durch die Verwendung von Filz als Filtermasse eine relativ große Filterfläche hat. Ferner kann das Vorfilter unabhängig vom Feinfilter 4 aus dem Gehäuse 2 herausgenommen bzw. gereinigt werden. Hierzu wird die Mutter 19 gelost und der Deckel 17 abgenommen, worauf sich der Vorfilter komplett aus dem Gehäuse 2 herausziehen lät, während das Feinfilter 4 davon unberührt bleibt.The construction shown has the advantage that the pre-filter 9, 10, a relatively large one, especially due to the use of felt as the filter material Has filter surface. Furthermore, the pre-filter can independently of the fine filter 4 from the Housing 2 can be removed or cleaned. For this purpose, the nut 19 is loosened and the cover 17 removed, whereupon the prefilter is completely out of the housing 2 can be pulled out, while the fine filter 4 remains unaffected.

Ein weiterer Vorteil ist die gedrängte, raumsparende Bauweise, da das Vorfilter 9, 10 das Feinfilter konzentrisch umschließt. Auf diese Weise ist es möglich, für zwei unabhängig voneinander arbeibande Filter mit einem einzigen Gehäuse auszukommen.Another advantage is the compact, space-saving design, there the pre-filter 9, 10 concentrically encloses the fine filter. That way is it possible for two independently arbeibande filters with a single one Housing get along.
