Description
Die Erfindung betrifft eine Vorrichtung zur Vorreinigung von kreislaufgeführten Wasser, insbesondere in aquatilen Anlagen mittels eines mechanischen Filters zur Abtrennung von Fäkalien und anderen partikulären Substanzen.The invention relates to a device for pre-cleaning of circulating water, especially in aquatilen plants by means of a mechanical filter for the separation of feces and other particulate substances.

Alle aus dem Stand der Technik bekannte Lösungen zur Reinigung von Wasser von Aquakulturen offenbaren als erste oder als eine der ersten Stufen der Reinigung eine mechanische Filterung des Wasser zur Entfernung von Fäkalien oder anderen partikulärer Substanzen mit anschließender Weiterleitung des Wasser in weitere Reinigungsstufen. Alle aufgezeigten mechanischen Filter weisen aber den Nachteil auf, dass sie nicht zu Reinigen und Wiederzuverwenden sind oder zur Reinigung aus der Filtereinheit ausgebaut und in einem getrennten Arbeitsgang gereinigt werden müssen. Die Filtereinheit oder der mechanische Filter lassen sich damit nicht in einem kontinuierlichen Produktionszyklus einsetzen. Da der Anteil von Fäkalien oder partikulärer Substanzen in Fischzuchtbecken nach kurzer Zeit hoch ist, werden die aus dem Stand der Technik bekannten mechanischen Filter in kurzer Zeit zugesetzt und müssen schon nach kurzer Zeit gegen neue mechanische Filter ausgetauscht werden. Damit ist eine erhebliche Verteuerung der Produktionskosten gegeben. Bei Bandfilter, die durch das mit Partikeln belastete Wasser zur Aufnahme der Partikel und somit zur mechanischen Reinigung von Wasser geführt werden und anschließend mittels Wasser und Luft mit Hochdruck von den Bändern entfernt werden, ist zwar eine kontinuierliche Filterung von Wasser möglich. Aber diese Bänder haben bei einem Einbau in Fischzuchtbecken einen erheblichen Platzbedarf, so dass für den eigentlichen Zweck der Fischzucht nur noch wenig Platz zur Verfügung steht. Aus diesem Grund sind diese Lösungen auch nur für die Reinigung von Wasser in der Landwirtschaft oder in der Fischverarbeitung einsetzbar.All known from the prior art solutions for the purification of aquaculture water reveal as a first or as one of the first stages of cleaning mechanical filtering of the water to remove fecal matter or other particulate substances with subsequent forwarding of the water in further purification stages. However, all shown mechanical filters have the disadvantage that they are not to be cleaned and reused or removed for cleaning from the filter unit and cleaned in a separate operation. The filter unit or the mechanical filter can thus not be used in a continuous production cycle. Since the proportion of faeces or particulate substances in fish tank after a short time is high, the known from the prior art mechanical filters are added in a short time and must be replaced after a short time against new mechanical filter. This is a significant increase in the cost of production. In band filters, which are guided by the particle-laden water for receiving the particles and thus for the mechanical purification of water and then removed by means of water and air at high pressure from the tapes, although a continuous filtering of water is possible. But these bands have a significant footprint when installed in fish tanks, so that for the actual purpose of fish farming is little space available. For this reason, these solutions are only used for the purification of water in agriculture or fish processing.
