Das vorliegende Gebrauchsmuster betrifft eine Vorrichtung zum Filtern von Feststoffen aus wäßrigen und nicht-wäßrigen Systemen.The present utility model relates to a device for filtering solids from aqueous and non-aqueous systems.
Die Vorrichtung zum Filtern gemäß der vorliegenden Erfindung ist dadurch gekennzeichnet, daß als Filtermaterial ein Verbundmaterial, das Viskose oder andere Faserstoffe in Form eines Vlieses oder Gewebes und darauf aufgebracht Polyethylen- Fasern oder andere Polymer-Fasern enthält, verwendet wird.The filtering device according to the present invention is characterized in that a composite material containing viscose or other fibrous materials in the form of a fleece or fabric and polyethylene fibers or other polymer fibers applied thereto is used as the filter material.
Filtermaterialien zum Entfernen von Feststoffen aus wäßrigen und nicht-wäßrigen Systemen sind bekannt. Zu nennen sind dabei insbesondere Watte und verschiedenartige Kunststoff-Materialien, wobei innerhalb dieser Gruppe insbesondere membranartige Materialien und Materialien mit poröser Schwammstruktur zu nennen sind.Filter materials for removing solids from aqueous and non-aqueous systems are known. These include, in particular, cotton wool and various types of plastic materials, with membrane-like materials and materials with a porous sponge structure being particularly noteworthy within this group.
Die bislang bekannten Materialien weisen jedoch relativ häufig Nachteile dahingehend auf, daß sie lediglich eine unzureichende Reinigungswirkung besitzen, oder, bei ausreichender Reinigungswirkung, relativ teuer sind.However, the materials known to date often have disadvantages in that they have only an inadequate cleaning effect or, even if they have sufficient cleaning effect, are relatively expensive.
Demgemäß lag dem vorliegenden Gebrauchsmuster die Aufgabe zugrunde, eine Filter-Vorrichtung bereit zu stellen, die sich dadurch auszeichnet, daß das verwendete Filtermaterial eine ausreichende Filterwirkung über einen vergleichsweise langen Zeitraum hinweg aufweist und gleichzeitig kostengünstig ist.Accordingly, the present utility model was based on the task of providing a filter device which is characterized in that the filter material used has a sufficient filtering effect over a comparatively long period of time and is at the same time cost-effective.
Diese Aufgabe wird durch die in den Ansprüchen definierte Vorrichtung zum Filtern von wäßrigen und nicht-wäßrigen Systemen gelöst.This object is achieved by the device defined in the claims for filtering aqueous and non-aqueous systems.
Die hierin beschriebene Vorrichtung zum Filtern ist dadurch gekennzeichnet, daß als Filtermaterial ein Verbundmaterial, das Viskose oder andere Faserstoffe, insbesondere Polyester oder Viskose, in Form eines Vlieses oder Gewebes und darauf aufgebracht, Polyethylen- oder andere Polymer-Fasern, insbesondere Polyethylen- oder Polypropylen-Fasern enthält. Vorzugsweise liegt das Flächengewicht der Polyethylen-Fasern zwischen 60 bis 180 g/m2, weiter bevorzugt bei 65 g/m2.The filtering device described here is characterized in that the filter material used is a composite material that contains viscose or other fiber materials, in particular polyester or viscose, in the form of a fleece or fabric and polyethylene or other polymer fibers, in particular polyethylene or polypropylene fibers, applied thereto. The basis weight of the polyethylene fibers is preferably between 60 and 180 g/m 2 , more preferably 65 g/m 2 .
Als Polymer-Fasern, die im Rahmen des vorliegenden Gebrauchsmuster insbesondere verwendet werden, sind neben den bereits erwähnten Polymeren, weitere Polyolefine zu nennen.In addition to the polymers already mentioned, other polyolefins are to be mentioned as polymer fibers that are particularly used within the scope of the present utility model.
Das bevorzugte Flächengewicht des Viskose- oder Faserstoff-Vlieses liegt im Bereich von 10 bis 60 g/m2, weiter bevorzugt bei 20 g/m2. Insbesondere bevorzugt ist ein Filtermaterial, das Polyethylen-Fasern und ein Viskose-Vlies umfaßt, deren Flächengewichte 65 bzw. 20 g/m2 betragen.The preferred basis weight of the viscose or fibrous fleece is in the range from 10 to 60 g/m 2 , more preferably 20 g/m 2 . Particularly preferred is a filter material which comprises polyethylene fibers and a viscose fleece, the basis weights of which are 65 and 20 g/m 2 , respectively.
Die Länge der Fasern wird vorzugsweise zwischen 1 und 60 mm in Abhängigkeit der Zusammensetzung des Florfaserstoffes variiert, weiter bevorzugt zwischen 5 und 10 mm variiert.The length of the fibers is preferably varied between 1 and 60 mm depending on the composition of the pile fiber material, more preferably varied between 5 and 10 mm.
Die Dicke der Fasern liegt vorzugsweise im Bereich zwischen 0,005 nun bis 0,125 mm, wobei der besonders bevorzugte Bereich zwischen 0,010 und 0,060 mm einzuordnen ist.The thickness of the fibers is preferably in the range between 0.005 mm and 0.125 mm, with the particularly preferred range being between 0.010 and 0.060 mm.
Durch die Kombination des Verbundmaterials sowie der Struktur der Fasern kann ein progressiver Filteraufbau erreicht werden, insbesondere dadurch, daß die Faserdicke an der Filteroberfläche vorzugsweise zwischen 0,005 und 0,-010 mm und an der Basis zwischen 0,02 und 0,040 mm beträgt.Through the combination of the composite material and the structure of the fibers, a progressive filter structure can be achieved, in particular by ensuring that the fiber thickness at the filter surface is preferably between 0.005 and 0.010 mm and at the base between 0.02 and 0.040 mm.
Die Dicke des Verbundmaterials liegt vorzugsweise im Bereich zwischen 1 und 10 mm, weiter bevorzugt bei 2 bis 4 mm.The thickness of the composite material is preferably in the range between 1 and 10 mm, more preferably 2 to 4 mm.
Die hier beschriebene Filtervorrichtung kann für alle wäßrigen und nicht-wäßrigen Systeme angewendet werden, solange diese das innerhalb der beschriebenen Filter-Vorrichtung verwendete Filtermaterial nicht angreifen.The filter device described here can be used for all aqueous and non-aqueous systems, as long as they do not attack the filter material used within the described filter device.
Als wäßrige Systeme kommen demgemäß alle wäßrigen Systeme in Frage, deren pH Wert in einem Bereich liegt, dem gegenüber die verwendeten Materialien beständig sind. Besonders geeignet ist die Filter-Vorrichtung für alle in Haus und Garten anfallenden wäßrigen Systeme, insbesondere Teiche und Aquarien, aber selbstverständlich auch zur weiteren Reinigung von aufgefangenem Regenwasser oder Brauchwassern.Accordingly, all aqueous systems whose pH value is in a range to which the materials used are resistant can be considered as aqueous systems. The filter device is particularly suitable for all aqueous systems in the home and garden, especially ponds and aquariums, but of course also for the further purification of collected rainwater or process water.
Als nicht-wäßrige Systeme sind verschiedene im Haushalt anfallende Ablüfte zu nennen, d.h. insbesondere Staubsaugerund Dunsthaubenabluft. Prinzipiell läßt sich jedoch die Filter-Vorrichtung gemäß des vorliegenden Gebrauchsmusters auch in industriellen Anlagen verwenden, solange die Zusammensetzung der anfallenden Abluft sich chemisch'inert gegenüber den eingesetzten Materialien verhält.Non-aqueous systems include various exhaust air that occurs in the home, i.e. in particular vacuum cleaner and cooker hood exhaust air. In principle, however, the filter device according to the present utility model can also be used in industrial plants, as long as the composition of the exhaust air is chemically inert to the materials used.

In einen Gartenteich, dessen Wasser bei visueller Beobachtung klar erschien, wurde eine Filter-Vorrichtung mit dem Material gemäß des Herstellungsbeispiels eingesetzt. Bereits nach 5 Tagen zeigte das Filtermaterial eine deutliche bräunliche Färbung und die Wasserqualität war sichtbar verbessert, d.h. wesentlich klarer. Die Filter-Vorrichtung mit demselben Filtermaterial wurde 6 Monate lang im Teich belassen. Innerhalb dieser Zeitspanne übernahm der Filter auch bakteriologische Reinigungsaufgaben durch Ansiedlung von Bakterien, die z.B. Fischkot und Futterreste verarbeiten. Im vorliegenden Fall erschien das Filtermaterial nach 6 Monaten gesättigt. Es wurde jedoch wegen seiner biologischen Filteraktivität nicht entfernt, sondern weiteres Filtermaterial zusätzlich in die Vorrichtung eingebracht. Nach weiteren 6 Monaten wurde das zuerst eingefüllte Material entfernt, da nunmehr das nach 6 Monaten eingeführte Filtermaterial genug Bakterien angesetzt hatte, um die biologische Reinigung fortzuführen. Gleichzeitig wurde zusätzlich neues Filtermaterial in die Filter-Vorrichtung eingebracht.A filter device with the material according to the manufacturing example was inserted into a garden pond whose water appeared clear when visually observed. After just 5 days, the filter material showed a clear brownish color and the water quality was visibly improved, i.e. significantly clearer. The filter device with the same filter material was left in the pond for 6 months. During this period, the filter also took on bacteriological cleaning tasks by colonizing bacteria that process, for example, fish excrement and leftover food. In the present case, the filter material appeared saturated after 6 months. However, it was not removed because of its biological filter activity, but additional filter material was added to the device. After a further 6 months, the material that had been added first was removed because the filter material introduced after 6 months had now developed enough bacteria to continue the biological cleaning. At the same time, new filter material was also added to the filter device.
Durch diese Wechselmethode war es möglich relativ kostengünstig und ohne großen Zeitaufwand eine gleichbleibende ausgezeichnete Wasserqualität im Versuchsteich sicherzustellen.This method of exchange made it possible to ensure consistently excellent water quality in the test pond relatively inexpensively and without great expenditure of time.
Zur Überprüfung der Reinigungsaktivität in stark verschmutzten wäßrigen Systemen wurde die in Beispiel 1 beschriebene Filter-Vorrichtung in einen Teich eingebracht, der überaus verschmutzt war, d.h. solche Mengen von grünem Schleim und Algen aufwies, daß die darin befindlichen Fische nur noch unmittelbar an der Oberfläche sichtbar waren. Vor dem Einsetzen der Filter-Vorrichtung war versucht worden, durch kommerziell erhältliche chemische Additive die WasserqualitätTo test the cleaning activity in heavily polluted aqueous systems, the filter device described in Example 1 was introduced into a pond that was extremely polluted, i.e. it contained such quantities of green slime and algae that the fish in it were only visible directly at the surface. Before installing the filter device, attempts had been made to improve the water quality using commercially available chemical additives.
dieses Teichs zu verbessern, was jedoch nicht gelang. Bei diesem Versuch wurde das Filtermaterial in der Filter-Vorrichtung anfänglich 5 mal nach je 5 Tagen gewechselt. Bereits nach 3 Wochen war das Wasser wesentlich klarer, so daß die Wechselzyklen entsprechend auf zunächst 14 Tage, dann 6 Wochen und schließlich ebenfalls auf 6 Monate, wie in Beispiel 1 beschrieben, ausgedehnt werden konnten. Nach ca. 6 Wochen war das Wasser kristallklar.of this pond, but this was not successful. In this experiment, the filter material in the filter device was initially changed 5 times, every 5 days. After just 3 weeks, the water was significantly clearer, so that the change cycles could be extended to 14 days, then 6 weeks and finally 6 months, as described in example 1. After about 6 weeks, the water was crystal clear.
Wie die oben beschriebenen Versuche zeigen, gelingt es mit der Filter-Vorrichtung gemäß Gebrauchsmuster überaus wirkungsvoll und schnell die Wasserqualität von Teichen ohne den Einsatz von Chemikalien zu verbessern.As the tests described above show, the filter device according to the utility model is extremely effective and quick at improving the water quality of ponds without the use of chemicals.
