Abstract
Description
Die Erfindung bezieht sich auf einen Filter zur Reinigung flüssiger Medien mit einem von einem Lochblech umgebenen, durchströmbaren und mehrlagig gefalteten Filtereinsatz aus stabilisierenden Geweben und Fliesen wobei der Filtereinsatz in zwei oder mehrere axial hintereinander angeordnete Filterstufen unterteilt ist, von denen die unmittelbar benachbarten Filterstufen jeweils unterschiedliche Filterfeinheiten aufweisen, sowie ein Verfahren zur Herstellung eines Filtereinsatzes für einen solchen Filter.The invention relates to a Filters for cleaning liquid Media with a flowable and surrounded by a perforated plate Multi-layer pleated filter insert made of stabilizing fabrics and tiles with the filter insert in two or more axially one behind the other arranged filter stages is divided, of which the immediate neighboring filter stages each have different filter finenesses have, as well as a method for producing a filter insert for one such a filter.
Ein Filter dieser Art ist durch die
Dies erfordert einen großen Zeit- und Arbeitsaufwand zur Herstellung des Filters, dennoch sind eine ausreichende mechanische Festigkeit und eine störungsfreie Funktion oftmals nicht gegeben. Die zwei aneinander anliegenden Fassungen zweier Filterstufen können nämlich eine potentielle Fehlerquelle darstellen. Des weiteren ist von Nachteil, dass durch die in Längsrichtung des Filters von den winkelförmig gestalteten Fassungen abstehenden Stege ein Teil der durchströmbaren Fläche der Filterstufen abgedeckt wird; der Filter ist, um dies auszugleichen, demnach in seiner axialen Länge größer zu bemessen.This takes a long time and labor to manufacture the filter, yet are one sufficient mechanical strength and trouble-free function often not given. The two adjacent versions of two filter stages can namely represent a potential source of error. Another disadvantage is that by the in the longitudinal direction of the filter from the angular designed projections part of the flowable area of the Filter stages is covered; to compensate for this, the filter is accordingly in its axial length larger.
Durch die
Aufgabe der Erfindung ist es daher, einen Filter der vorgenannten Gattung in der Weise auszugestalten, dass dieser nicht nur eine hohe mechanische Festigkeit aufweist und auf seiner gesamten axialen Länge durchströmbar ist, vor allem, dass der mit zwei oder mehreren hintereinander angeordneten Filterstufen versehene Filter praktisch in einem Arbeitsgang herstellbar ist. Die Fertigung des Filters soll demnach in kurzer Zeit und auf wirtschaftliche Weise zu bewerkstelligen sein.The object of the invention is therefore to design a filter of the aforementioned type in such a way that it not only has a high mechanical strength and can be flowed through over its entire axial length, especially that of two or more arranged in a row Filters provided with filter stages can be produced practically in one operation is. The production of the filter should therefore be quick and easy to be economically viable.
Gemäß der Erfindung wird dies bei einem Filter der vorgenannten Art dadurch erreicht, dass zur Verbindung zweier benachbarter Filterstufen des Filters zwei Feinfiltervliese unterschiedlicher Filterfeinheiten im Stoßbereich überlappend angeordnet und die Gewebe über die Länge des Filtereinsatzes durchgehend verlaufend angeordnet sind.According to the invention, this is at achieved a filter of the aforementioned type in that for connection two adjacent filter stages of the filter two fine filter fleeces different filter fineness overlapping in the joint area and the Tissue over the length of the filter insert are arranged continuously.
Zweckmäßig ist es hierbei, den Geweben ein Vorfiltervlies und/oder ein Schutzvlies zuzuordnen und jeweils zwei Feinfiltervliese mit unterschiedlichen Filterfeinheiten überlappend miteinander zu verbinden, beispielsweise zu verpressen. Außrdem sollten die Feinfiltervliese auf einer zur Fertigung geeignete Länge von ca. 5 mm bis 30 mm übereinander liegend angeordnet sein.It is useful here, the tissues assign a pre-filter fleece and / or a protective fleece and each overlapping two fine filter fleeces with different filter finenesses to connect with each other, for example to press. They should also Fine filter fleece on a length of suitable for production approx. 5 mm to 30 mm one above the other be arranged horizontally.
Das Verfahren zur Herstellung eines in dieser Weise ausgebildeten Filters ist dadurch gekennzeichnet, dass die Feinfiltervliese unterschiedlicher Filterfeinheiten zusammen mit Geweben und gegebenenfalls mit einem Vorfiltervlies und/oder einem Schutzvlies verpresst und gleichzeitig gefaltet werden.The process of making a Filter designed in this way is characterized by that the fine filter fleeces of different filter fineness together with fabrics and optionally with a pre-filter fleece and / or pressed into a protective fleece and folded at the same time.
Werden bei einem Filter zwei Feinfiltervliese unterschiedlicher Feinheiten im Stoßbereich überlappend angeordnet, so ist dieser nicht nur sehr einfach und somit kostengünstig z.B. auf einer Plissiermaschine zu erstellen, sondern dieser weist auch eine hohe mechanische Stabilität, da eine Stoßfuge entfällt, auf. Zwischen zwei Filterstufen sind nämlich keine Halterungen mehr erforderlich, die Filterstufen gehen vielmehr, ohne dass Fassungen anzubringen und miteinander zu verbinden sind, nahtlos ineinander über. Ein Filtereinsatz mit unterschiedlichen Filterfeinheiten kann demnach in einem Arbeitsgang gepresst und gefaltet werden.If two filters are different with one filter Delicacies overlapping in the joint area arranged, this is not only very simple and therefore inexpensive e.g. to create on a pleating machine, but this one also points high mechanical stability, there is a butt joint does not apply on. There are no more brackets between two filter stages required, the filter stages go rather without sockets are to be attached and connected with each other, seamlessly over one another. On Filter insert with different filter fineness can therefore can be pressed and folded in one operation.
Des weiteren ist von Vorteil, dass die Gewebe und ein Vorfiltervlies und/oder ein Schutzvlies sich über die gesamte axiale Länge des Filtereinsatzes erstrecken und keine Trennstellen vorhanden sind, so dass auch keine Abdeckungen zwischen den Filterstufen in Kauf genommen werden müssen. Die axiale Baulänge eines vorschlagsgemäß ausgebildeten Filters kann daher verkürzt werden. Bei reduziertem Fertigungsaufwand wird somit ein Filter geschaffen, durch den eine störungsfreie Betriebsweise über einen langen Zeitraum sichergestellt ist und der auf einfache Weise durch die Wahl der Filterfeinheiten an den jeweiligen Einsatzbereich bei optimalen Strömungsverhältnissen anpassbar ist.Another advantage is that the fabric and a pre-filter fleece and / or a protective fleece over the total axial length of the filter insert and there are no separation points are so that there are no covers between the filter stages in Purchase must be made. The axial length one trained according to the proposal Filters can therefore be shortened become. With a reduced manufacturing effort, it becomes a filter created by a trouble-free Operation via one long period of time is ensured and in a simple manner the choice of filter fineness to the respective area of application optimal flow conditions is customizable.
In der Zeichnung ist ein Ausführungsbeispiel des gemäß der Erfindung ausgebildeten Filters dargestellt, das nachfolgend im einzelnen erläutert ist. Hierbei zeigt:In the drawing is an embodiment of the according to the invention trained filter shown, the following in detail explained is. Here shows:
