Abstract

To achieve the best possible uniform pulping in a pulper in a shorter time with favourable energy input, it is proposed to optimise geometrical measurements of the base rotor (12) arranged at the base of the pulper vessel (2), and of a transport screw (6) directed towards the rotor and the arrangement of the screw. The lower end (14) of the transport helical screw (6) extends to the immediate vicinity of the highest point of the base rotor (12). The distance between the end of the transport screw (6) and the highest point of the base rotor (12) is smaller than 1/10 of the diameter of the base rotor (12). The diameter of the imagined circular surface of the lowest screw flight is about one third to one quarter of the diameter of the base rotor (12). The generatrix of the helix is inclined downwards to the axis of the transport screw (6) in the transport direction. Flat deflector plates are arranged on the inner circumference of the vessel (2) to direct the flow in the direction of the middle of the vessel (2). In this way, formation of a vortex in the transport flow in the vessel is prevented and a favourable toroidal transport flow is created. <IMAGE>
