S2, an electric stirrer (1) works, stirring blades (8) at the end part of an output shaft of the electric stirrer stir pulp and cotton fibers, meanwhile, a motor (12) works, after the motor (12) is decelerated by a reduction gearbox (13), the motor (12) gives a rotor blade (7) proper rotating speed through a transmission component (10), the rotor blade (7) is matched with a stator blade (4) in the rotating process, an oblique upward centrifugal force is given to the cotton fibers by an inner tooth (21) and an outer tooth (19) in a meshing manner, the cotton fibers are thrown into a return pipe (3), and the port of the return pipe (3) is communicated with the top end opening of a pulp tank (2), so that the cotton fibers are automatically circulated into the pulp tank (2);
s3, after the step of maintaining the step S2 for 30-45min, turning off the electric stirrer (1) and the motor (12);
s4, when the rotor blade (7) needs to be retracted, the rotor blade (7) is selectively retracted by using the manual blade feeding and retracting mechanism (16) and the electric blade feeding and retracting mechanism (17).
