Dry sea island method of highland and its device

摘要

The present invention provides a dry seaweed method and a device of the highland, which can be processed into long fibers without mechanically tearing the paper and tearing it into pieces, without dividing the pulp fibers of the paper as much as possible.;On the inner surface of the gas flow path, a cross-sectional wave shaped wall surface is provided, and the air flows having a velocity component in a direction parallel to the wall surface and a velocity component in a vertical direction colliding with the wall surface flows, thereby finely cutting the raw material hill. It is returned to the air stream and flows through the gas flow path.;Further, the parallel velocity component of the air flow is 40 m or more per second. Furthermore, in the high-dry dry island apparatus which accommodates a radial rotary blade in the circular casing main body which has an inlet and an outlet, and installs a wavy tooth shape in the inner peripheral surface of the circular casing main body, it is a raw material suctioned with airflow from the inlet. Using a cut in advance, the distance L0 between the outer circumferential end of the disk of the radial rotor blade and the tip end of the wavy tooth of the circular casing body is 10 times or more the thickness of the raw material sheet, and at the same time the distance L0 and the wing The ratio L0 / W of the rotation axis direction width W of the board | substrate 22 shall be 0.3 or less, and the circumferential speed of the said radial rotating blade 20 shall be 40 m or more per second.
