Description

Regenwasser-FilternalageRainwater filter system

Die Neuerung betrifft eine Regenwasser-Filteranlage, die über zwei nacheinander geschaltete Filterflächen das gefilterte Regenwasser in einen Regenwasser-Behälter gibt.The innovation concerns a rainwater filter system that uses two filter surfaces connected one after the other to feed the filtered rainwater into a rainwater tank.

Vorrichtungen oder Anlagen dieser Art haben bisher nur eine Filterfläche, die meist schräg zur Fließrichtung des Regenwassers angeordnet ist. Das Regenwasser mit Verunreinigungen fließt über das Sieb und wird dort von der Verunreinigung getrennt. Danach fließt das Regenwasser in einen Regenwasser-Behälter.Devices or systems of this type have so far only had one filter surface, which is usually arranged at an angle to the direction of flow of the rainwater. The rainwater with impurities flows over the sieve and is separated from the impurities there. The rainwater then flows into a rainwater tank.

Die abgefilterten Verunreinigungen sollen über das Sieb mit Restwasser nach außen abgeschwemmt werden.The filtered impurities should be washed out through the sieve with residual water.

All diese Vorrichtungen und Anlagen haben den Nachteil, daß sie mit der Zeit verschmutzen und dann nur noch, je nach Verschmutzungsgrad, sehr wenig Regenwasser zum Regenwasser-Behälter durchlassen.All of these devices and systems have the disadvantage that they become dirty over time and then, depending on the degree of contamination, only allow very little rainwater to pass through to the rainwater tank.

Des weiteren haben die Siebe den Nachteil, daß sie normal gewebt, mit Ober- und Unterfaden, sind. Durch diese Webart entstehen Vertiefungen, in denen sich der Schmutz sehr gut ablagern kann. Diese Ablagerungen reduzieren natürlicherweise die freie Durchgangsfläche des Filters. Je mehr Filterfläche derartig verstopft, um so mehr Restwasser fließt mit der Verunreinigung Richtung Regenabwasserkanal oder zur Versickerung. Der Wirkungsgrad der Filterung wird durch die stetige Verschmutzung des Filtersiebes reduziert.Another disadvantage of the sieves is that they are woven in the normal way, with upper and lower threads. This type of weave creates depressions in which dirt can easily settle. These deposits naturally reduce the free passage area of the filter. The more the filter surface is clogged in this way, the more residual water flows with the contamination towards the storm sewer or to the infiltration system. The efficiency of the filter is reduced by the constant contamination of the filter sieve.

Aufgabe der vorliegenden Neuerung ist es, eine Regenwasser-Filtervorrichtung oder Anlage vorzuschlagen, von der Verunreinigungen leicht abrutschen können und die Filterfläche so gestaltet wird, daß sie über längere Zeit nicht verstopft.The aim of this innovation is to propose a rainwater filter device or system from which contaminants can easily slide off and the filter surface is designed in such a way that it does not become clogged over a long period of time.

Anhand vieler Versuche wurde ein Filtersieb entwickelt, das einen einwandfreien Transport der Verunreinigungen über das Filtersieb Richtung Regenabwasser gewährleistet. Ein zweites Sieb wurde dahinter geschaltet um eventuelle Restwassermengen abzufiltern. Hierdurch wird ein Wirkungsgrad von nahezu 100 % erreicht.Based on many tests, a filter screen was developed that ensures that the impurities are transported perfectly through the filter screen towards the rainwater. A second screen was installed behind it to filter out any residual water. This achieves an efficiency of almost 100%.

Die Neuerung ist dadurch gekennzeichnet, daß das Filtersieb eine Webart nach der bekannten Fünfschaft-Atlas-Bindung aufweist und mit den Schußdrähten in Richtung Regenabwasser positioniert ist und ein zweites Sieb dahinter geschaltet ist, welches eine Restwassermenge gefiltert in den Regenwasserbehälter läßt.The innovation is characterized by the fact that the filter screen has a weave based on the well-known five-shaft Atlas weave and is positioned with the weft wires in the direction of the rainwater and a second screen is connected behind it, which allows a residual amount of water to be filtered into the rainwater tank.

Das Sieb ist an der Oberseite durch die Fünfschaft-Atlas-Bindung wesentlich glatter als an der Unterseite. Auf der Oberseite, wo das Regenwasser auftrifft, liegen die Schußdrähte über eine große Strecke in Fließrichtung. Hierdurch können auf der glatten Oberseite die Verunreinigungen besser in Richtung Abwasser rutschen.The five-shaft satin weave makes the top of the sieve much smoother than the bottom. On the top, where the rainwater hits, the weft wires lie in the direction of flow over a large distance. This allows the impurities to slide more easily towards the wastewater on the smooth top.

Die Neuerung wird anhand der Zeichnungen erläutert.

It shows:

Fig. 1: Eine Regenwasser-Filteranlage schematisch im SchmittFig. 1: A rainwater filter system schematically in the Schmitt

In der Fig. (1) wird schematisch eine Regenwasser-Filteranlage (2) gezeigt, die aus einem Behälter (8) mit einem Regenwasser-Zulauf (3), einem Wasserablauf (4) zum Regenwasserbehälter, einem Wasserablauf (5) zum Regenwasserbehälter, einem Filtersieb (6) und einem Filtersieb (7), sowie einer Öffnung (9) und einer Öffnung (10) besteht.In Fig. (1) a rainwater filter system (2) is shown schematically, which consists of a container (8) with a rainwater inlet (3), a water outlet (4) to the rainwater container, a water outlet (5) to the rainwater container, a filter sieve (6) and a filter sieve (7), as well as an opening (9) and an opening (10).

Der, der Neuerung zugrunde liegende, Regenwasser-Filter wird durch die Öffnung (3) mit verunreinigtem Regenwasser gespeist. Dieses Regenwasser trifft zuerst auf das Filtersieb (6). Die Hauptwassermenge tritt durch das Filtersieb (6) und gelangt in Richtung Wasserablauf (4) in den Regenwasser-Behälter. Die Restwassermenge, mit großen Schmutzanteilen, gelangt auf das Filtersieb (7). Das Filtersieb (7) ist tiefer angeordnet als das Filtersieb (6). Dadurch kann sich in diesem verbleibenden Raum die Verunreinigung ansammeln. Die Restwassermenge gelangt durch das Filtersieb (7) über den Wasserablauf (5) in den Regenwasser-Behälter. Über die Öffnung (9) kann das Filtersieb (6) entnommen und dann gereinigt werden. Über die öffnung (10) kann das Filtersieb (7) mit der Verschmutzung entnommen und reinigt werden.The rainwater filter on which the innovation is based is fed with contaminated rainwater through the opening (3). This rainwater first hits the filter screen (6). The majority of the water passes through the filter screen (6) and flows into the rainwater tank in the direction of the water drain (4). The remaining water, with large amounts of dirt, reaches the filter screen (7). The filter screen (7) is positioned lower than the filter screen (6). This allows dirt to collect in this remaining space. The remaining water flows through the filter screen (7) via the water drain (5) into the rainwater tank. The filter screen (6) can be removed via the opening (9) and then cleaned. The filter screen (7) with the dirt can be removed and cleaned via the opening (10).
