Abstract

Ein Zellstofftrockner weist eine Presse (P1) und einen Umlauf eines kontinuierlichen Stützsiebs (2) auf, welches wasserdurchlässig ist und welches zusammen mit einer Pulpebahn (W) zwischen die einen Pressspalt begrenzenden Pressflächen eingeführt ist, um Wasser von der Bahn in Richtung des Stützsiebs (2) zu entfernen. Eine Entwässerungseinrichtung ist, von dem Stützsieb betrachtet, auf der anderen Seite der Pulpebahn (W) zum Entwässern der Bahn in der entgegengesetzten Richtung vorgesehen. Ein Umlauf eines Entwässerungsfilzes (1a) ist innerhalb des Umlaufs des Stützsiebs (2) angeordnet und zwischen das Stützsieb (2) und die den Pressspalt begrenzenden Pressflächen eingeführt. Die Pressflächen der Presse (P1) bilden einen langen Spalt.A pulp dryer has a press (P1) and a circulation of a continuous support wire (2), which is permeable to water and which is introduced together with a pulp web (W) between the press nip defining pressing surfaces to remove water from the web in the direction of the support wire (Fig. 2) to remove. A dewatering device, viewed from the support screen, is provided on the other side of the pulp web (W) for dewatering the web in the opposite direction. A circulation of a dewatering felt (1a) is disposed within the circulation of the support wire (2) and inserted between the support wire (2) and the press nip defining pressing surfaces. The pressing surfaces of the press (P1) form a long gap.
