Description

Die Erfindung betrifft einen Desodorierungsfilter mit einem Auffangtrichter und anschließendem Filtergehäuse, wobei der Auffangtrichter einen Boden mit einem Wassereinlauf aufweist.The invention relates to a deodorization filter with a Collecting funnel and subsequent filter housing, the Collecting funnel a floor with a water inlet having.

Übliche kommunale Kanalsysteme sind heute durch Kanalschächte zugänglich. Diese Kanalschächte dienen zum einen dem Ableiten von beispielsweise Oberflächenwasser, zum anderen aber auch der Inspektion des gesamten Kanalsystems.Common municipal sewer systems today are through manholes accessible. On the one hand, these manholes serve deriving surface water, for example but also the inspection of the entire sewer system.

Bekannt ist, daß in diesen Kanalsystemen unangenehme Gerüche entstehen oder aber Abwässer mit unangenehmen Gerüchen weitergeleitet werden. Diese Gerüche steigen durch die Kanalschächte nach oben und entweichen, weshalb jeder Kanalschacht stinkt.It is known that these duct systems have unpleasant smells arise or waste water with unpleasant smells to get redirected. These smells rise through the Manholes up and escape, which is why everyone Sewer shaft stinks.

Aus der FR-A 2 641 299 ist ein Desodorierungsfilter für ein Abtritts- oder Toilettenablaufsystem bekannt, bei welchem ein Filtergehäuse aus mehreren Teilen besteht, wobei in das Filtergehäuse eine entfernbare Filterpatrone eingesetzt werden kann.FR-A 2 641 299 describes a deodorization filter for a Exit or toilet drain system known, in which a filter housing consists of several parts, in which Filter housing a removable filter cartridge is inserted can be.

Um einerseits Oberflächenwasser auf einfache Art ableiten zu können, andererseits aber dem Entweichen unangenehmer Gerüche aus dem Kanalsystem entgegen zu wirken, bietet die EP-A-0 626 189 einen Desodorierungsfilter an, bei dem um ein Fallrohr in einem Filtergehäuse herum Filtermaterial angeordnet ist. Um ein Zusammensacken des Filtermaterials zu verhindern, befindet sich in dem Filtermaterial ein Stützgerüst.To drain surface water in a simple way to be able to, but on the other hand the escape uncomfortable The counteracts odors from the sewer system EP-A-0 626 189 discloses a deodorization filter in which around a downpipe in a filter housing around filter material is arranged. A sagging of the filter material to prevent is in the filter material Scaffolding.

Obwohl dieser Desodorierungsfilter bereits sehr gute Resultate bringt, hat sich in der Praxis gezeigt, daß er Nachteile aufweist. Ein wesentlicher Nachteil besteht darin, daß zum Austauschen des Filtermaterials immer der gesamte Desodorierungsfilter herausgenommen und entweder das Filtermaterial fachmännisch an Ort und Stelle ausgetauscht oder aber der gesamte Desodorierungsfilter zum Hersteller zurückgeschickt werden muß. Ferner hat sich bei der Anordnung des Fallrohres innerhalb des Filtermaterials herausgestellt, daß sich das Filtermaterial nicht so eng an das Fallrohr anschmiegt, so daß Abluft vor allem in der Nähe des Fallrohres nach oben abgeleitet wird. Diese Abluft ist dann keiner Reinigung durch das Filtermaterial ausgesetzt, so daß es zu unangenehmen Gerüchen kommt.Although this deodorizing filter already has very good results has shown in practice that he Disadvantages. A major disadvantage is that to replace the filter material always the whole Deodorization filter removed and either that Filter material professionally replaced on the spot or the entire deodorization filter to the manufacturer must be sent back. Furthermore, the arrangement the downpipe inside the filter material, that the filter material is not so close to the Down pipe nestles so that exhaust air is especially close of the downpipe is diverted upwards. This exhaust air is then not exposed to cleaning by the filter material, so that there are unpleasant smells.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Filterwirkung des Desodorierungsfilters nochmals zu verbessern und gleichzeitig die Handhabung wesentlich zu erleichtern.The present invention is based on the object To further improve the filtering effect of the deodorization filter while making handling much easier.

Zur Lösung dieser Aufgabe führt, daß in das Filtergehäuse eine entfernbare Filterpatrone eingesetzt ist, wobei der Wassereinlauf in ein Gehäuse einmündet, das einen Wasserauslauf außerhalb des Filtergehäuses aufweist. To solve this problem that leads to the filter housing a removable filter cartridge is inserted, the Water inlet flows into a housing that one Has water spill outside the filter housing.

Die entfernbare Filterpatrone hat den großen Vorteil, daß sie ohne fachmännische Kenntnisse aus dem Filtergehäuse herausgenommen und durch eine neue ersetzt werden kann. Die alte Filterpatrone wird dann entweder von einem Fachmann neu gefüllt oder an das Herstellerwerk zurückgegeben. Hierdurch wird die Handhabung und Benutzung des Desodorierungsfilters über eine lange Lebensdauer hin sehr vereinfacht.The removable filter cartridge has the great advantage that without any specialist knowledge from the filter housing can be removed and replaced with a new one. The old filter cartridge is then either replaced by a specialist refilled or returned to the manufacturing plant. This will handle and use the Deodorization filter over a long lifespan simplified.

Bevorzugt weist die Filterpatrone einen Boden, zumindest einen Zwischenboden und einen Deckel auf. Zwischen diesen Böden bzw. Deckeln sind jeweils Filterräume gebildet, in denen sich das Filtermaterial befindet. Selbstverständlich können in diesen Räumen auch entsprechende Stützgerüste od. dgl. angeordnet sein, wie sie in der EP-A-0 626 189 beschrieben sind.The filter cartridge preferably has a bottom, at least an intermediate shelf and a lid. Between these Bottoms or lids are each formed in filter spaces where the filter material is. Of course can also support scaffolding in these rooms. Like. Be arranged as in EP-A-0 626 189 are described.

Damit die Luft durch die Filterpatrone hindurchgelangen kann, sind im Boden, Zwischenböden und Deckel jeweils Luftöffnungen, bevorzugt als Luftschlitze, angeordnet. Da die Filterpatrone doch ein gewisses Gewicht aufweist, hat es sich als ratsam erwiesen, die Luftschlitze im Boden so auszugestalten, daß in etwa mittig ein Steg stehen bleibt, der als Bügel zum Herausziehen der Filterpatrone aus dem Filtergehäuse dienen kann.So that the air can pass through the filter cartridge can be in the floor, intermediate floors and lids Air openings, preferably arranged as air slots. There the filter cartridge has a certain weight it turned out to be advisable to vent the louvers in the floor like this to design that a web remains in the middle, the as a bracket for pulling out the filter cartridge from the Filter housing can serve.

Ferner weist die Filterpatrone bevorzugt nahe dem Boden einen umlaufenden Randstreifen auf, durch den beispielsweise Schrauben als Befestigungselement eingesetzt werden können. Über diese Befestigungselemente kann dann die Filterpatrone mit dem Filtergehäuse verbunden werden.Furthermore, the filter cartridge preferably has near the floor a circumferential edge strip through which, for example Screws are used as a fastener can. The filter cartridge can then be attached to these fasteners be connected to the filter housing.

Das versetzte Anordnen des Wasserauslaufes hat auch den Vorteil, daß die Filterpatrone selbst einfacher ausgestaltet werden kann. The offset arrangement of the water outlet also has the Advantage that the filter cartridge itself is made simpler can be.

Selbstverständlich könnte auch noch der Wassereinlauf in dem Boden des Auffangtrichters versetzt angeordnet sein, jedoch soll er bevorzugt gleichzeitig auch als Auslaß für die gereinigte Abluft dienen. In diesem Fall werden zusätzliche Stege für das Auslassen der Abluft, wie sie noch in der EP-A-0 626 189 beschrieben sind, vermieden, so daß im vorliegenden bevorzugten Ausführungsbeispiel auch ein dem Desodorierungsfilter gegenüber dem Kanalschacht abdichtender gummiartiger Ringkragen unnötig wird. Auf die Außenwand des Auffangtrichters kann jetzt ein Dichtring aufgesetzt werden, der sich einem ändernden Abstand zwischen der bevorzugt konisch ausgebildeten Ringwand des Auffangtrichters und dem Kanalschacht anpassen kann. Hierdurch wird in jedem Fall eine sehr gute Abdichtung zwischen dem Desodorierungsfilter und dem Kanalschacht erzielt, so daß Abluft auf diesem Wege nicht mehr aus dem Kanalschacht ausdringen kann. Die Abluft muß in jedem Fall die Filterpatrone durchziehen.Of course, the water inlet could also be in be arranged at the bottom of the collecting funnel, however, it should preferably also serve as an outlet for serve the cleaned exhaust air. In this case, additional Bridges for exhausting the exhaust air like they still do are described in EP-A-0 626 189 avoided, so that also in the present preferred embodiment the deodorization filter sealing against the manhole rubbery ring collar becomes unnecessary. On the A sealing ring can now be used on the outer wall of the collecting funnel be put on, the changing distance between the preferably conical ring wall of the Collecting funnel and the manhole. Hereby in any case a very good seal between the deodorization filter and the manhole, so that exhaust air no longer comes out of the Can penetrate manhole. The exhaust air must in any case pull the filter cartridge through.

Dem Wasserauslauf sollte eine Verschlußeinrichtung zugeordnet sein. Dabei kann es sich beispielsweise um eine Ventileinrichtung oder um einen Siphon handeln. Der Siphon macht sich durch entsprechende Rohrkrümmungen zunutze, daß ein stehenbleibender Wasserstand den Wasserauslauf verschließt.A closure device should be assigned to the water outlet his. This can be, for example Act valve device or a siphon. The siphon takes advantage of appropriate pipe bends that a constant water level at the water outlet closes.

Eine einfache Ventileinrichtung kann aus einer Wippe bestehen, die drehbar zwischen zwei Lagerstreifen gehalten ist. Einererseits befindet sich an dieser Wippe eine Klappe, die den Wasserauslauf verschließt, andererseits ein Gewicht. Das Gewicht ist schwerer als die Klappe, so daß die Klappe immer gegen den Wasserauslauf gedrückt wird. Drängt dagegen Wasser durch den Wasserauslauf, wird die Klappe geöffnet. Selbstverständlich sind hier auch noch andere Ausgestaltungen von Verschlußeinrichtungen möglich und sollen im Rahmen der Erfindung liegen. A simple valve device can be made from a seesaw exist, which are rotatably held between two bearing strips is. On the one hand there is one on this seesaw Flap that closes the water outlet on the other hand Weight. The weight is heavier than the flap, so that the flap is always pressed against the water outlet. However, if water is forced through the water outlet, the Flap opened. Of course, here are still other configurations of locking devices possible and should be within the scope of the invention.

Damit die Abluft durch die Filterpatrone und aus dem Wassereinlauf austreten kann, weist das Gehäuse bevorzugt nahe dem Boden des Auffangtrichters Luftöffnungen auf. Dies gewährleistet, daß Wasser aus dem Gehäuse nicht durch diese Luftöffnung versehentlich in die Filterpatrone überlaufen kann, dennoch kann die gefilterte Luft in das Gehäuse ein- und aus dem Wassereinlauf austreten. So that the exhaust air through the filter cartridge and out of the water inlet can emerge, the housing preferably has near openings at the bottom of the collecting funnel. This ensures that water from the casing is not through this Air opening accidentally spilled into the filter cartridge can, nevertheless the filtered air can enter the housing and emerge from the water inlet.

  • Figure 1 is a partially broken side view of a deodorization filter according to the invention in an exploded view;
  • Figure 2 is a bottom view of the deodorization filter according to the invention according to Figure 1;
  • Figure 3 is a perspective view of a filter cartridge according to the invention.

    • Ein Desodorierungsfilter R gemäß Figur 1 ist dazu geeignet, in einen nicht näher gezeigten Kanalschacht eingesetzt zu werden. Hierzu weist der Desodorierungsfilter R ein Filtergehäuse 1 auf, in welches eine Filterpatrone 2 einsetzbar ist.A deodorization filter R according to FIG. 1 is suitable for inserted in a manhole, not shown to become. For this purpose, the deodorization filter R a filter housing 1 into which a filter cartridge 2 can be used.

    Filtergehäuse 1 und Filterpatrone 2 sind bevorzugt teilzylindrisch augebildet. Dabei weist die Filterpatrone 2 einen etwas geringeren Durchmesser d1 als der Durchmesser d des Filtergehäuses 1 auf, so daß die Filterpatrone 2 ohne Schwierigkeiten in das Filtergehäuse 1 eingeschoben werden kann und die in Figur 1 gestrichelt dargestellte Gebrauchslage einnimmt.Filter housing 1 and filter cartridge 2 are preferably partially cylindrical. The filter cartridge 2 has a somewhat smaller diameter d 1 than the diameter d of the filter housing 1, so that the filter cartridge 2 can be inserted into the filter housing 1 without difficulty and assumes the position of use shown in dashed lines in FIG.

    Dem Filtergehäuse 1 ist nach oben hin ein Auffangtrichter 4 angeformt, dessen umlaufende Ringwand 5 bevorzugt konisch ausgebildet ist. Die Ringwand 5 umfängt einen Boden 6, der lediglich etwa mittig einen Wassereinlauf 7 aufweist. Dieser Wassereinlauf 7 ist in Figur 2 gestrichelt angedeutet. Der Wassereinlauf 7 bildet, wie später noch näher beschrieben wird, gleichzeitig einen Reingasausgang. The filter housing 1 is a collecting funnel 4 upwards molded, the circumferential ring wall 5 preferably conical is trained. The ring wall 5 includes a bottom 6, the only has a water inlet 7 approximately in the middle. This water inlet 7 is dashed in Figure 2 indicated. The water inlet 7 forms, as later is described in detail, a clean gas outlet.

    Der Auffangtrichter 4 dient der Aufnahme eines nicht näher gezeigten Sandfanges, der über entsprechende Befestigungselemente mit dem Auffangtrichter verbunden ist. Dabei weist der Sandfang in der Regel einen Bügel auf, über den der gesamte Desodorierungsfilter R aus einem Schacht angehoben bzw. in einen Schacht eingesetzt werden kann.The collecting funnel 4 does not serve to receive one shown sand trap, the corresponding fasteners is connected to the collecting funnel. It points the sand trap usually has a bracket over which the entire deodorization filter R raised from a shaft or can be used in a shaft.

    Einer Unterfläche 8 des Bodens 6 ist gemäß den Figuren 1 und 2 ein geschlossenes Gehäuse 9 angesetzt. Von oben her mündet in dieses Gehäuse 9 der Wassereinlauf 7, während einem Gehäuseboden 10 ein Wasserauslauf 11 angeformt ist. Diesem Wasserauslauf 11 ist wiederum eine Ventileinrichtung 12 zugeordnet, die der Einfachheit halber aus einem Klappenventil bestehen kann. Dabei ist einerseits mit einer Wippe 13 eine Klappe 14 und andererseits ein Gewicht 15 verbunden. Die Wippe 13 selbst ist zwischen zwei Lagerstreifen 16.1 und 16.2 drehbar gelagert, so daß die Klappe 14 unter dem höheren Gewicht des Gewichtes 15 in Schließlage an dem Wasserauslauf 11 gehalten wird.A lower surface 8 of the bottom 6 is, according to FIGS and 2 a closed housing 9 is attached. From above flows into this housing 9, the water inlet 7 while a water outlet 11 is molded onto a housing base 10. This water outlet 11 is in turn a valve device 12 assigned, for the sake of simplicity from a Flap valve can exist. On the one hand, there is a Rocker 13 a flap 14 and on the other hand a weight 15 connected. The rocker 13 itself is between two Bearing strips 16.1 and 16.2 rotatably mounted so that the Flap 14 under the higher weight of the weight 15 in Closed position is held on the water outlet 11.

    Nahe dem Boden 6 sind in Seitenwände 17 des Gehäuses 9 Luftschlitze 18 eingeformt, über die Luft aus dem Filtergehäuse 1 und durch den Wassereinlauf 7 entweichen kann.Near the bottom 6 are in side walls 17 of the housing 9 Louvers 18 molded over the air from the filter housing 1 and can escape through the water inlet 7.

    Wie oben erwähnt, ist die Filterpatrone 2 in das Filtergehäuse 1 eingesetzt. Zu diesem Zweck weist gemäß Figuren 2 und 3 die Filterpatrone 2 einen einen Boden 19 umlaufenden Randstreifen 20 auf, der über entsprechende Befestigungselemente 21 mit dem Filtergehäuse 1 verbunden ist.As mentioned above, the filter cartridge 2 is in the filter housing 1 used. For this purpose, according to FIG and 3 the filter cartridge 2 has a bottom 19 surrounding it Edge strip 20 on the corresponding fasteners 21 is connected to the filter housing 1.

    Gegenüber dem Boden 19 ist die Filterpatrone 2 durch einen entfernbaren Deckel 22 verschlossen. Zwischen Deckel 22 und Boden 19 befindet sich zumindest ein Zwischenboden 23, durch den die Filterpatrone 2 in zwei Kammern 24.1 und 24.2 aufgeteilt ist. Beide Kammern 24.1 und 24.2 sind mit entsprechendem Filtermaterial gefüllt. Sie können noch weitere Stützgerüste für das Filtermaterial aufweisen, wie dies beispelsweise in der EP-A-0 626 189 beschrieben ist.Across from the floor 19 is the filter cartridge 2 by a removable cover 22 closed. Between cover 22 and Floor 19 is at least one intermediate floor 23, through which the filter cartridge 2 in two chambers 24.1 and 24.2 is divided. Both chambers 24.1 and 24.2 are with appropriate filter material filled. You can still have further support structures for the filter material, such as this is described, for example, in EP-A-0 626 189.

    Damit eine Abluft die Filterpatrone 2 durchdringen kann, weisen Boden 19, Zwischenboden 23 und Deckel 22 entsprechende Schlitze 25.1, 25.2 und 25.3 auf, die zwischen sich Stege 26 bilden. Ein mittiger Steg 26.1 gemäß Figur 2 dient als Bügel zum Herausziehen der Filterpatrone 2 aus dem Filtergehäuse 1. Deshalb kann dieser Steg 26.1, falls gewünscht, verstärkt ausgebildet sein.So that exhaust air can penetrate the filter cartridge 2, have floor 19, intermediate floor 23 and cover 22 corresponding Slots 25.1, 25.2 and 25.3 open between them Form webs 26. A central web 26.1 according to FIG. 2 serves as a bracket for pulling out the filter cartridge 2 from the Filter housing 1. Therefore, this web 26.1, if desired to be more trained.

    Diese Ausgestaltung des Desodorierungsfilters R gestattet, daß anstelle eines aus der EP-A-0 626 189 bekannten gummiartigen Ringkragens ein gummiartiger Dichtring 27 verwendet werden kann, der verschiebbar der Ringwand 5 von außen her anliegt. Dies hat den Vorteil, daß sich dieser Dichtring 27 beim Einsetzen des Desodorierungsfilters R in einen Kanalschacht dem Schachtdurchmesser anpassen kann, so daß auf jeden Fall eine Abdichtung erfolgt, auch wenn Passungenauigkeiten bestehen. Bei den bekannten Desodorierungsfiltern mit dem gummiartigen Ringkragen traten immer wieder unerwünschte Luftdurchlässe zwischen Schacht und Desodorierungfilter auf.This configuration of the deodorization filter R allows that instead of a rubber-like known from EP-A-0 626 189 Ring collar used a rubber-like sealing ring 27 can be slidably the annular wall 5 of outside. This has the advantage that this Sealing ring 27 when inserting the deodorization filter R in can adjust a manhole to the shaft diameter, so that there is definitely a seal, even if There are inaccuracies in fit. With the known deodorization filters kicked with the rubbery ring collar undesired air outlets between the shaft and deodorization filter.

    Die Funktionsweise der vorliegenden Erfindung ist folgende:The operation of the present invention is as follows:

    Wasser, welches in dem Auffangtrichter 4 gesammelt wird, kann durch den Wassereinlauf 7 in das Gehäuse 9 abgeleitet werden. Es wird dann nach außen zum Wasserauslauf 11 geleitet und kann durch die Ventileinrichtung 12 in ein Fallrohr oder direkt in den Kanal auslaufen. Denkbar ist hier auch die Zwischenschaltung einer siphonartigen Rohrkrümmung, die ein Stehenlassen eines entsprechenden Wasserpegels erlaubt, durch den keine Abluft in das Gehäuse zurückgelangen kann. Water, which is collected in the collecting funnel 4, can be discharged through the water inlet 7 into the housing 9 become. It is then directed outside to the water outlet 11 and can through the valve device 12 in one Downpipe or run directly into the sewer. Is conceivable here also the interposition of a siphon-like pipe bend, the standing a corresponding water level allowed through which no exhaust air into the housing can go back.

    Abluft aus dem Kanalsystem gelangt durch die Schlitze 25.1, 25.2 und 25.3 in die Filterpatrone 2, wobei die Abluft durch das Filtermaterial gereinigt wird. Die Abluft tritt dann als Reingas aus den Schlitzen 25.3 des Deckels 22 aus und gelangt durch die Luftschlitze 18 und den Wasserauslauf 11 nach außen. Ein Ausdringen von Kanalgerüchen ist damit verhindert.Exhaust air from the duct system passes through the slots 25.1, 25.2 and 25.3 in the filter cartridge 2, the exhaust air is cleaned by the filter material. The exhaust air enters then as clean gas from the slots 25.3 of the cover 22 and passes through the louvers 18 and the water outlet 11 outwards. This means that channel odors can escape prevented.
