Rotor for a pulper manufacturing device and a pulper device comprising such a rotor

摘要

PROBLEM TO BE SOLVED: To provide a rotor for a pulper production apparatus, which reduces vibration of the pulper production apparatus and achieves excellent energy efficiency.SOLUTION: The rotor for a pulper production apparatus includes: a rotor body part 1a having a plurality of blade parts 1c...; a cap part 6 which is provided on the rotor body part 1a with the apex thereof positioned on or substantially on a rotary axis ax and has a substantially conical shape widened from the upper part toward the lower part thereof; and a plurality of pump blade parts 10... provided on a side peripheral surface S6 of the cap part 6 so as to extend from intermediate positions on the side peripheral surface S6 of the cap part 6 to a plurality of respective blade parts 1c... provided outward from the rotor body part 1a, and so as to be curved in a convex manner toward the rotation direction of the rotor body part 1a. A wall surface Wb of each of the plurality of pump blade parts 10..., which is located rearward with respect to the rotational direction of the rotor body part 1a, is sloped so as to be widened from the upper part of each of the plurality of pump blade parts toward the lower part thereof.
