Title (EN) DEVICE FOR FILTERING A PLASTIC MELT
(FR) DISPOSITIF DE FILTRATION D'UNE MATIÈRE PLASTIQUE EN FUSION
(DE) VORRICHTUNG ZUM FILTRIEREN EINER KUNSTSTOFFSCHMELZE
Abstract:
(EN) The invention relates to a device for filtering a plastic melt, comprising a housing (1) which has at least one inlet channel (2) and at least one outlet channel (3) for the plastic melt. The at least one inlet channel (2) is separated from the at least one outlet channel (3) by at least one filter cavity (4) for receiving at least one filter pin (5) which can be moved axially in the cavity. The at least one filter pin (5) has at least one filter main part (6) with a filter surface (7) comprising filter openings (8) which pass through the filter main part (6) and through which the plastic melt passes into a filter cavity (9) in the filter main part (6). The filter cavity (9) is fluidically connected to the at least one outlet channel (3), the filter surface (7) of the filter main part (6) is surrounded by a pleated filter screen (12), and clamping elements (14 and 14') are provided in smoothed axial edge regions (11 and 11') of the pleated filter screen (12).
(FR) L'invention concerne un dispositif de filtration d'une matière plastique en fusion, comprenant un boîtier (1) qui comporte au moins un conduit d'entrée (2) et au moins un conduit de sortie (3) destiné à la matière plastique en fusion, l'au moins un conduit d'entrée (2) étant séparé de l'au moins un conduit de sortie (3) par au moins une cavité de filtre (4) destinée à recevoir au moins un axe de filtre (5) déplaçable axialement, l'au moins un axe de filtre (5) comportant au moins un élément de base de filtre (6) possédant une surface de filtre (7) pourvue d'orifices de filtre (8) qui traversent l'élément de base de filtre (6) et qui permettent le passage de la matière plastique en fusion vers une cavité de filtrat (9) formée dans l'élément de base de filtre (6), la cavité de filtrat (9) étant en liaison fluidique avec l'au moins un conduit de sortie (3), la surface de filtre (7) de l'élément de base de filtre (6) étant entourée par un tamis de filtre plissé (12) et des éléments de serrage (14 et 14') étant prévus dans les zones de bord (11 et 11') axiales lissées du tamis de filtration plissé (12).
(DE) Vorrichtung zum Filtrieren einer Kunststoffschmelze, mit einem Gehäuse (1), welches zumindest einen Eintrittskanal (2) und zumindest einen Austrittskanal (3) für die Kunststoffschmelze aufweist, wobei der zumindest eine Eintrittskanal (2) von dem zumindest einen Austrittskanal (3) durch zumindest einen Eilterhohlraum (4) zur Aufnahme zumindest eines darin axial verschiebbaren Filterbolzens (5) getrennt ist, wobei der zumindest eine Filterbolzen (5;) zumindest einen Filtergrundkörper (6) mit einer Filterfläche (7) mit dort durch den Filtergrundkörper (6) durchtretenden Filteröffnungen (8) aufweist, durch welche die Kunststoffschmelze zu einem Filtrathohlraum (9) im Filtergrundkörper (6) durchtritt, wobei der Filtrathohlraum (9) mit dem zumindest einen Austrittskanal (3) in Fluidverbindung steht, wobei die Filterfläche (7) des Filtergrundkörpers (6) von einem : plissierten Filtersieb (12) umfasst ist und in axialen geglätteten Randbereichen (11 und. 11') des plissierten Filtersiebs (12) Klemm elemente (14 und 14') vorgesehen sind..
