Abstract

Einrichtung zur Reinigung einer Fasersuspension für die Papiererzeugung von in dieser enthaltenen Fremdstoffen, wie Sand, Metallteilen, Glassplittern, Rindenteilen u.dgl., unter Verwendung eines rohrförmigen, vertikal ausgerichteten Gehäuses (1,2,3), welches mit einem Einlass (10) für die unter Druck erfolgende Einbringung der Fasersuspension in dieses Gehäuse (1,2,3), weiters an seinem unteren Ende mit einem Auslass (30) für das Abführen der in der Fasersuspension enthaltenen Fremdstoffe und an seinem oberen Ende mit einem Auslass (20) für das Ableiten der von den Fremdstoffen gereinigten Fasersuspension ausgebildet ist. Dabei sind zumindest ein Teil des Gehäuses (1,2,3) bzw. der unteren Gehäuseteile (2,3) aus einem transparenten oder einem durchsichtigen Material, insbesondere aus einem transparenten bzw. einem durchsichtigen Kunststoffmaterial, hergestellt.

Figure imgaf001
Device for cleaning a fiber suspension for the paper production of foreign substances contained therein, such as sand, metal parts, glass fragments, bark parts and the like, using a tubular, vertically oriented housing (1, 2, 3), which is provided with an inlet (10) for the pressurized introduction of the fiber suspension into this housing (1, 2, 3), further at its lower end with an outlet (30) for discharging foreign substances contained in the fiber suspension and at its upper end with an outlet (20) is designed for the derivation of the fiber suspension purified from the foreign substances. In this case, at least a part of the housing (1, 2, 3) or of the lower housing parts (2, 3) is made of a transparent or a transparent material, in particular of a transparent or a transparent plastic material.
