Abstract
Description
Die Erfindung betrifft einen Biofilter zum Einbau in Abflusssysteme, mit einem Auffangtrichter und anschliessenden Filtergehäuse für aufsteigende Abluft sowie einer Ablauföffnung für Oberflächenwasser.The invention relates to a biofilter for installation in Drainage systems, with a funnel and subsequent filter housing for rising exhaust air as well a drain hole for surface water.
Aus der US-A 5 632 889 ist ein Filter zum Reinigen von Abwasser bekannt, bevor dieses in einen Abwasserkanal gelangt. Hierbei wird das Wasser durch einen Filter geleitet, der in einem Gehäuse hängt und aus diesem Gehäuse entfernbar ist.From US-A 5 632 889 is a filter for cleaning Waste water is known before it enters a sewer arrives. Here, the water passes through a filter passed, which hangs in a housing and out of this housing is removable.
Ein Filter der o.g. Art ist bspw. aus der EP 0 745 731 A1 bekannt. Nachteilig bei diesem Filter ist, dass er insgesamt als Einheit hergestellt ist, der in einen Kanalschacht eingesetzt wird. Sofern die Kanalschächte unterschiedliche Durchmesser oder Ausgestaltungen aufweisen, muss zumindest das Einsatzteil dieses Filters dem Schacht angepasst werden.A filter of the above Art is, for example, from EP 0 745 731 A1 known. The disadvantage of this filter is that it is made as a whole, into one Duct shaft is used. If the manholes different diameters or configurations must have at least the insert part of this filter be adapted to the shaft.
Ferner ist zum Austausch des Filtermaterials bzw. zum Reinigen des Filters notwendig, den gesamten Filter aus dem Schacht zu nehmen. Dieser ist schwer und schwierig zu handhaben. Ausserdem werden häufig die notwendigen Abdichtungen verletzt.Furthermore, to replace the filter material or Clean the filter necessary to remove the entire filter from the Take shaft. This is difficult and difficult too handle. In addition, the necessary are often Seals violated.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Biofilter der o.g. Art zu entwickeln, der in unterschiedlichste Schächte passt und leicht zu handhaben ist.The present invention is based on the object a biofilter from the above Kind of develop in different shafts fit and easy to handle is.
Zur Lösung dieser Aufgabe
werden ein Biofilter mit den Merkmalen des
Anpruchs 1 und ein Verfahren zum Herstellen
eines Biofilters mit den Merkmalen des
Anpruchs 12 vorgeschlagen.To solve this task
become a biofilter with the characteristics of
Der wesentliche Kern der vorliegenden Erfindung liegt darin, dass der Montagering immer im Schacht verbleibt, während nur das Filtergehäuse herausgenommen und ausgetauscht bzw. gereinigt wird. In einem normalen Schacht stützt sich der Montagering, wie bereits bekannt, über einen Rundgummi gegen die Schachtwand ab. Da der Montagering beim Austausch der Filterpatrone bzw. Reinigen des Einsatzes nicht aus dem Schacht genommen wird, ist der Rundgummi auch keinem Verschleiss ausgesetzt. Weist der Schacht eine andere Abmessung auf, ist es möglich, den Montagering in den Schacht einzuschäumen, so dass eine sehr gute Dichtung und auch Halterung des Montagerings stattfindet. Damit kann ein derartiger Montagering und mit ihm auch der erfindungsgemässe Biofilter für alle bestehenden Schächte verwendet werden. The essential essence of the present invention lies in that the mounting ring always remains in the shaft, while just removing the filter housing and is exchanged or cleaned. In a normal shaft As already known, the mounting ring is supported by a round rubber against the shaft wall. Since the Mounting ring when replacing the filter cartridge or cleaning of the insert is not removed from the shaft Round rubber also not exposed to wear. He knows If another dimension opens up, it is possible to Foam mounting ring in the shaft, making a very good seal and also mounting ring mounting takes place. Such a mounting ring and with him also the inventive biofilter for everyone existing shafts can be used.
Sollten die Schächte einen unterschiedlichen Durchmesser oder einen unterschiedlichen Querschnitt aufweisen, so braucht lediglich der Montagering diesem Unterschied angepasst zu werden oder aber der Montagering wird dann in einen Adapter eingepasst, der dem jeweiligen Schacht angepasst ist. Hierdurch ist es auch möglich, bspw. mehrere Biofilter in einem grossen Schacht nebeneinander anzuordnen, die zum Austauschen oder Reinigen aus dem Adapter bzw. dem entsprechend angepassten Montagering gezogen werden.Should the shafts have a different diameter or have a different cross section, so only the mounting ring needs this difference to be adjusted or the mounting ring is then in an adapter fitted to the respective shaft is adjusted. This also makes it possible, for example, several Biofilters side by side in a large shaft to arrange for replacement or cleaning from the Adapter or the correspondingly adapted mounting ring to be pulled.
Mit dieser Ausgestaltung ist auch der Sandfang nicht mehr Halter für den gesamten Filter, so dass er ebenfalls aus Kunststoff hergestellt werden kann. Damit wird er wesentlich leichter und kann separat entfernt werden.With this configuration, the sand trap is also no longer Holder for the entire filter, so that it too Plastic can be made. With that he will much easier and can be removed separately.
Das Filtergehäuse ist mit dem Filteroberteil verbunden, welches einer Innendichtung und diese wiederum dem Innenflansch an dem Montagering aufliegt. Somit sind Filteroberteil und Filtergehäuse, ggfs. zusammen mit einem noch zu erwähnenden Deckel zu einem Einsatz verbunden, der zum Austausch des Filtermaterials oder zum Reinigen insgesamt aus dem Montagering herausgezogen werden kann. Dieser Einsatz ist wesentlich leichter, da er insgesamt bzw. seine Einzelteile aus Kunststoff hergestellt werden können.The filter housing is connected to the upper part of the filter, which an inner seal and this in turn the Inner flange rests on the mounting ring. So are Filter upper part and filter housing, possibly together with a still to be mentioned lid connected to an insert which to replace the filter material or for cleaning can be pulled out of the assembly ring. This use is much easier since it is overall or its individual parts are made of plastic can.
Die Innendichtung, die bevorzugt einseitig auf dem Innenflansch klebend ausgebildet ist, verbleibt bei Herausnahme des Einsatzes auf dem Innenflansch und wird nicht verletzt, so dass ihre Funktion nicht beeinträchtigt wird.The inner seal, which is preferred on one side on the Inner flange is designed to remain adhesive Removal of the insert on the inner flange and will not injured so that their function is not impaired becomes.
Bevorzugt soll sich der Montagering über einen Dichtring gegen eine Schachtwand abstützen. Dieser Dichtring ist querschnittlich D-förmig ausgestaltet und besitzt dabei einen etwa geraden Rücken sowie einen gekrümmten Teil. Der gerade Rücken soll starrer ausgebildet sein, als der gekrümmte Teil. Dies hat den Vorteil, dass das Herausnehmen und das Einsetzen des Montageringes in den Schacht wesentlich erleichtert ist, da der Dichtring nicht wegrollt, sondern durch den geraden Rücken an dem Montagering anliegend bleibt.The mounting ring should preferably be over a sealing ring support against a shaft wall. This sealing ring is cross-sectionally D-shaped and has an approximately straight back and a curved part. The straight back should be more rigid than that curved part. This has the advantage of being removed and inserting the mounting ring into the shaft is much easier since the sealing ring is not rolled away, but through the straight back on the The mounting ring remains attached.
Um das Herausnehmen und Einsetzen noch weiter zu erleichtern, sollen in den Dichtring Löcher eingeformt sein, aus denen Luft aus einem Innenraum entweichen kann. Hierdurch kann der Durchmesser des Dichtringes verringert werden, ohne dass der Dichtring aus seiner Lage um den Montagering versetzt wird.To further remove and insert holes, should be formed in the sealing ring holes from which air can escape from an interior. This can reduce the diameter of the sealing ring without the sealing ring coming out of its position around the Mounting ring is moved.
Der gesamte Biofilter soll in einem wesentlich einfacheren Herstellungsverfahren aus Kunststoff geformt werden. Dazu sind nur zwei Formen notwendig, wobei eine Form für das Filtergehäuse und zumindest eine Zwischenplatte bestimmt ist, während in der anderen Form der Montagering, der Deckel und das Filteroberteil geformt wird. Durch entsprechende Schnittlinien werden dann die einzelnen Teile voneinander getrennt. Durch zumindest eine Schnittlinie wird eine mit Schlitzen versehenen Zwischenplatten aus dem Boden des Filtergehäuses herausgeschnitten. Wird der Boden in entsprechend längeren Wellen ausgestaltet, so können sogar zwei Zwischenplatten herausgeschnitten werden.The entire biofilter is said to be in a much simpler Manufacturing processes are molded from plastic. To only two forms are necessary one shape for the filter housing and at least one Intermediate plate is intended while in the other form the mounting ring, the lid and the filter upper part are shaped becomes. By means of appropriate cutting lines, the separate parts from each other. By at least one Cutting line becomes a slotted one Intermediate plates from the bottom of the filter housing cut out. The floor will be longer accordingly Shafts designed, so can even two intermediate plates be cut out.
Der Deckel und das Filteroberteil werden jeweils von einer Seite des Montageringes abgeschnitten.The cover and the filter top are each one Cut off the side of the mounting ring.
Beim Zusammenbau wird der Deckel in das Filteroberteil eingesetzt und dort verschweisst. Der Deckel dient im wesentlichen der Auflage des Sandfangs. Er bildet aber auch eine Ablauföffnung aus, durch die Wasser in einen Ablauf im Filteroberteil fallen kann. Dieser Ablauf im Filteroberteil ist bevorzugt durch eine selbstschliessende Klappe verschlossen, wobei diese Klappe bzw. der entsprechende Klappenmechanismus ebenfalls an das Filteroberteil angeschweisst wird. When reassembling the cover is in the filter top used and welded there. The lid serves in the essential of the support of the sand trap. But it also forms a drain opening through which water flows into a drain in the Filter top can fall. This process in the upper part of the filter is preferred by a self-closing flap closed, this flap or the corresponding Flap mechanism also on the filter upper part is welded on.
