Abstract

The invention relates to a filter for filtering gaseous media contaminated with moisture and/or oil and/or solid particles. According to the invention, a pot-shaped filter element (5) is placed inside a housing (1, 4), in particular, between the inlet (2) and the outlet (3). A pre-filter (6), which can be easily removed and which functions like a cyclone filter, is located at the entry of the filter element (5). The operating costs of a filter of this type are low by virtue of the fact that the serviceable life of the actual filter is long and that the pre-filter, which can be easily replaced, does result in the accrual of any significant costs.

Description

Die Erfindung betrifft ein Filter für mit Feuchtigkeit und/oder Öl und/oder Feststoffpartikeln verunreinigte, gasförmige Medien mit einem einen Einlaß und einen Auslaß für das gasförmige Medium aufweisenden Gehäuse und einem darin untergebrachten topfförmigen Filterelement, dessen Filtermittel zwischen dem Einlaß und dem Auslaß angeordnet ist.The invention relates to a filter for moisture and / or contaminated oil and / or solid particles, gaseous media with an inlet and an outlet for the gaseous medium housing and a pot-shaped filter element housed therein, the Filter media between the inlet and the outlet is arranged.

Bei einem bekannten Filter dieser Art, das seit Jahrzehnten in der Praxis eingesetzt wird, mündet der Einlaß axial in das in der Regel oben offene und unten durch eine Kappe verschlossene topfförmige Filterelement. Das zu reinigende Medium wird so gezwungen, durch die zylindrische Wand in die Kammer des Gehäuses und von hier zu dem Auslaß zu strömen. Feuchtigkeitspartikel, Ölpartikel und/oder Feststoffpartikel werden von dem Filtermittel des Filterelementes zurückgehalten. Je nach Art des Filtermittels wird dabei mehr oder weniger Feuchtigkeit aufgrund des Koaleszenseffektes abgeschieden und tropft nach unten in das Gehäuse, wo es über einen Kondensatablauf abgeführt werden kann.In a known filter of this type that has been Is used for decades in practice Inlet axially into the generally open top and bottom cup-shaped filter element closed by a cap. The medium to be cleaned is forced by the cylindrical wall in the chamber of the housing and from here to flow to the outlet. Moisture particles, Oil particles and / or solid particles are removed from the Filter means of the filter element retained. Depending on The type of filter medium becomes more or less Moisture deposited due to the coalescence effect and drips down into the case where it's over one Condensate drain can be removed.

Neben dieser Art von topfförmigen Filtern, bei denen das zu reinigende Medium mehr oder weniger axial und radial das Filtermittel durchströmt, gibt es Zyklonfilter, insbesondere mit Koaleszenswirkung, in denen das zu reinigende Medium mit einer Drallströmung in ein hohlzylindrisches Filterelement eingeleitet wird. Die Drallströmung begünstigt die Abscheidung der im gasförmigen Medium enthaltenen verunreinigenden Partikel an der Wand des Filterelementes.In addition to this type of cup-shaped filter, where the Medium to be cleaned more or less axially and radially through the filter medium, there are cyclone filters, especially with coalescing effects, in which that too cleaning medium with a swirl flow in one  hollow cylindrical filter element is introduced. The Swirl flow favors the separation of the im gaseous medium containing contaminating particles on the wall of the filter element.

Der Erfindung liegt die Aufgabe zugrunde, ein Filter mit einem topfförmigen, insbesondere auf dem Koaleszenseffekt beruhenden Filterelement zu schaffen, das eine lange Standzeit hat.The invention has for its object to provide a filter a cup-shaped, especially on the coalescence effect based filter element to create a long Has service life.

Diese Aufgabe wird mit einem Filter der eingangs genannten Art gelöst, bei dem in Durchströmrichtung vor dem Filtermittel ein als Zyklonfilter mit Koaleszenseffekt ausgebildetes Vorfilter austauschbar angeordnet ist.This task is done with a filter at the beginning mentioned type solved in the flow direction before the filter medium as a cyclone filter Pre-filter designed to be interchangeable is arranged.

Bei dem erfindungsgemäßen Filter werden wegen des leicht austauschbaren Vorfilters wesentliche Teile der das zu reinigende Medium verunreinigenden Stoffe ausgefiltert, so daß die Standzeit des für die Filterleistung maßgeblichen Hauptfilters erheblich verlängert ist. Das führt auch zu einer kostengünstigen Betriebsweise, weil das die Filterleistung bestimmende Hauptfilter wesentlich höhere Beschaffungskosten verursacht als das leicht austauschbare aber auch leicht zu reinigende Zyklonfilter.In the filter according to the invention are easy because of the replaceable pre-filter essential parts of that too filtering out cleaning medium contaminating substances, so the life of the filter performance relevant main filter is significantly extended. The also leads to an inexpensive mode of operation because the main filter determining the filter performance is essential higher procurement costs than easily interchangeable but also easy to clean Cyclone filter.

Um die Wirksamkeit des Filters zu verbessern, ist nach einer Ausgestaltung der Erfindung vorgesehen, daß das Filtermittel die Form eines Hohlzylinders hat, in dessen oberem Ende das Vorfilter sitzt, das als unten offener Hohlzylinder mit einem an seinem oberen offenen Ende angeordneten Drallerzeuger ausgebildet ist. To improve the effectiveness of the filter is after an embodiment of the invention provided that Filter medium has the shape of a hollow cylinder in the the prefilter sits at the top, which is more open at the bottom Hollow cylinder with an open end at its upper end arranged swirl generator is formed.  

Um die Filterwirkung weiter zu verbessern und die Standzeit des Vorfilters zu verlängern, sollte das Filtermittel des Vorfilters eine Koaleszenswirkung haben.To further improve the filter effect and the To extend the life of the pre-filter should Filter media of the pre-filter have a coalescing effect.

Im folgenden wird die Erfindung anhand einer ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. Die Zeichnung zeigt das Filter im Axialschnitt.In the following the invention is based on a Exemplary embodiment drawing closer explained. The drawing shows the filter in the Axial section.

Das in der Zeichnung dargestellte Filter weist ein Gehäuse auf, das aus einem Kopf 1 mit einem Einlaß 2 und einem Auslaß 3 und aus einem am Kopf 1 dicht anschließbaren Topf 4 besteht. Der Einlaß 2 mündet axial und zentral im Topf 4, während der Eingang zum Auslaß 3 exzentrisch liegt.The filter shown in the drawing has a housing which consists of a head 1 with an inlet 2 and an outlet 3 and a pot 4 which can be connected tightly to the head 1 . The inlet 2 opens axially and centrally in the pot 4 , while the entrance to the outlet 3 is eccentric.

In dem Topf 4 ist koaxial ein topfförmiges Filterelement 5 untergebracht. Das Filterelement 5 weist einen geschlossenen Boden 5a und ein hohlzylindrisches Filtermittel 5b sowie einen Kopf 5c auf, mit dem es am Kopf 1 des Gehäuses dicht angeschlossen ist, so daß das zu reinigende Medium in das Innere des zylinderförmigen Filterelementes gelangt und gezwungen ist, die zylindrische Wand des Filtermittels 5b zu durchströmen.A pot-shaped filter element 5 is accommodated coaxially in the pot 4 . The filter element 5 has a closed bottom 5 a and a hollow cylindrical filter means 5 b and a head 5 c, with which it is tightly connected to the head 1 of the housing, so that the medium to be cleaned enters the interior of the cylindrical filter element and is forced to flow through the cylindrical wall of the filter medium 5 b.

Dem Filterelement 5 ist ein Vorfilter 6 in Form eines Zyklonfilters mit Koaleszenswirkung vorgeordnet. Das Zyklonfilter besteht aus einem unten offenen zylindrischen Filtermittel 6a und einem am oberen Ende angeordneten Drallerzeuger 6b in Form von Leitschaufeln. Die Anordnung ist dabei so getroffen, daß das über den Einlaß 2 einströmende gasförmige Medium gezwungen ist, den Drallerzeuger 6b zu passieren. Dabei wird die im wesentlichen lineare Strömung in eine rotierende Strömung umgesetzt, so daß beim weiteren Weg des gasförmigen Mediums durch das hohlzylindrische Filtermittel 6a sich Flüssigkeitspartikel und Feststoffpartikel am Filtermittel 6a, insbesondere unter Ausnutzung der Koaleszens, abscheiden. Das bedeutet, daß nur noch die im gasförmigen Medium verbliebenen restlichen Verunreinigungen vom Hauptfilter 5 ausgefiltert werden müssen. Entsprechend länger ist deshalb die Standzeit des Hauptfilters 5. Das auswechselbare Vorfilter 6 sollte aus einem preiswerten und/oder leicht zu reinigenden Filtermaterial bestehen, damit die Betriebskosten des Filters auch bei einem häufigen Wechsel des Vorfilters 6 niedrig bleiben.The filter element 5 is preceded by a pre-filter 6 in the form of a cyclone filter with a coalescing effect. The cyclone filter consists of a cylindrical filter means 6 a open at the bottom and a swirl generator 6 b arranged at the upper end in the form of guide vanes. The arrangement is such that the flowing in via the inlet 2 gaseous medium is forced to pass the swirl generator 6 b. The essentially linear flow is converted into a rotating flow, so that as the gaseous medium travels further through the hollow cylindrical filter medium 6 a, liquid particles and solid particles separate out on the filter medium 6 a, in particular using the coalescence. This means that only the remaining impurities in the gaseous medium have to be filtered out by the main filter 5 . The service life of the main filter 5 is therefore correspondingly longer. The replaceable prefilter 6 should consist of an inexpensive and / or easy-to-clean filter material, so that the operating costs of the filter remain low even when the prefilter 6 is changed frequently.
