Title:
WET PULP MATERIAL PROCESSING MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/161494
Kind Code:
A1
Abstract:
In vertical concentrating washing machines, processed raw material is transported upward but ends up containing shower water. That is, the moisture content ends up increasing during the transport process even though the material has been dewatered. A transport blade (8) has a plate-like shape in plan view and includes a fan-shaped portion (10) that extends rearward in the rotational direction, developing into a fan shape, and the transport blade is attached such that a plate surface thereof has a slanted orientation with respect to the axial direction of a rotary shaft (6), with a forward side, in the rotational direction, of the plate surface being disposed lower than a rearward side thereof. A plurality of the transport blades (8) are attached so as to delineate a helix along the circumferential direction of the rotary shaft (6) while leaving a communicating portion that is straight in the vertical direction. Shower water falls from gaps (S) between the transport blades (8). The transport blades (8) have a fan shape that widens toward the inner wall side of a rotary drum (5). A surface area on which the material rests stably and a sufficient gap (S) are secured in a well-balanced fashion.
