SHELL, DEFIBRATED MATERIAL TRANSPORT DEVICE AND USED PAPER REGENERATOR

摘要

To provide a shell capable of preventing the shell from adhesion of a defibrated material; a defibrated material transport device; and a used paper regenerator.SOLUTION: A shell for conveying defibrated material containing disintegrated fibers by air flow, the shell has a bend formed in the middle of the extending direction, and a plurality of grooves extending in the extending direction of the shell are formed on the inner surface of the shell on the outer peripheral side of the bend. The plurality of grooves preferably include a groove parallel to the central axis of the shell and a groove inclined within ± 30° with respect to the central axis of the shell.SELECTED DRAWING: Figure 7
