Abstract
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Filteranordnung und einem Fördermodul nach der Gattung der unabhängigen Ansprüche.The invention relates to a filter assembly and a conveyor module according to the preamble of the independent claims.
Die
Die
Beispielsweise aus dem oben genannten Stand der Technik bekannte saugseitige Filter haben den Vorteil, dass sowohl die Förderpumpe wie auch das Dosiermodul vor dem Schmutz geschützt wird. Saugseitige Filter sind nicht den hohen Drücken der Druckseite ausgesetzt, die eine stabilere Konstruktion des Filters samt Gehäuse notwendig macht.For example, known from the above-mentioned prior art suction-side filter have the advantage that both the feed pump and the metering module is protected from dirt. Suction-side filters are not exposed to the high pressures of the pressure side, which makes a more stable construction of the filter and housing necessary.
Offenbarung der ErfindungDisclosure of the invention
Die erfindungsgemäße Filteranordnung bzw. das erfindungsgemäße Fördermodul mit den kennzeichnenden Merkmalen der unabhängigen Ansprüche haben demgegenüber den Vorteil eines zuverlässigen Betriebs- mit hoher Filtereffizienz und gutem Schutz einer nachgeordneten Pumpe des Fördermoduls. Die Filteranordnung ist zuverlässig als Feinfilter gestaltbar beziehungsweise einsetzbar. Es wird in vorteilhafter Weise verhindert, dass die bei einem Feinfilter auftretende Luftabscheidung auf der Schmutzseite des Filters zu einer drastisch verringerten Filterfläche führt, d. h. es können keine Betriebszustände der Filteranordnung bzw. des Fördermoduls eintreten, bei denen je nach verwendetem Filtrationsmaterial die effektive Filterfläche bis auf 3 Prozent der ursprünglich wirksamen Fläche reduziert würde. Die saugseitig angeordnete Filteranordnung insbesondere in ihrer Verwendung bzw. Ausgestaltung als Feinfilter wird auf der Schmutzseite vollautomatisch und wirksam entlüftet.The filter assembly according to the invention or the conveying module according to the invention with the characterizing features of the independent claims have the advantage of a reliable operating with high filtration efficiency and good protection of a downstream pump of the delivery module. The filter arrangement can be reliably designed or used as a fine filter. It is advantageously prevented that occurring in a fine filter air separation on the dirty side of the filter leads to a drastically reduced filter surface, d. H. no operating states of the filter arrangement or of the delivery module can occur in which, depending on the filtration material used, the effective filter area would be reduced to 3 percent of the originally effective area. The filter assembly arranged on the suction side, in particular in its use or design as a fine filter, is fully automatically and effectively vented on the dirty side.
Weitere Vorteile ergeben sich durch die in den abhängigen Ansprüchen genannten Merkmale.Further advantages result from the features mentioned in the dependent claims.
Durch das Vorsehen von Schutzsieben im Bereich einer Umgehungsleitung beziehungsweise eines Ventils der Umgehungsleitung wird darüber hinaus zuverlässig verhindert, dass Schmutz auf die Sauberseite der Filteranordnung gelangt, wenn eine Entlüftung stattfindet.The provision of protective screens in the region of a bypass line or a valve of the bypass line also reliably prevents dirt from reaching the clean side of the filter arrangement when venting takes place.
Eine Venturiverengung im Bereich des Filterablaufs sorgt in vorteilhafter Weise für ein zügiges Absaugen etwaig im Ansaugbereich bzw. der Schmutzseite des Filters angesammelter Luft.Venturi constriction in the region of the filter outlet advantageously ensures rapid extraction of any air accumulated in the intake area or the dirty side of the filter.
Ein Ventil, insbesondere ein Schwimmerventil, der Umgehungsleitung sorgt in einfacher Weise dafür, dass nur in dem Moment eine Verbindung zwischen Schmutzseite und Reinseite des Filters besteht, in der sich Luft auf der Schmutzseite befindet. Sobald nur das zu filternde Fluid auf der Schmutzseite vorhanden ist, wird die Verbindung zur Reinseite wieder verschlossen. Damit ist ausgeschlossen, dass Schmutz auf die Reinseite gelangt.A valve, in particular a float valve, the bypass line ensures in a simple manner that only at the moment there is a connection between dirty side and clean side of the filter, in which there is air on the dirty side. As soon as only the fluid to be filtered is present on the dirty side, the connection to the clean side is closed again. This eliminates the possibility of dirt reaching the clean side.
Weitere Vorteile ergeben sich durch die in den weiteren abhängigen Ansprüchen und in der Beschreibung genannten Merkmale.Further advantages result from the features mentioned in the further dependent claims and in the description.
