The invention discloses an
impeller of a ring flaker. The
impeller comprises an
impeller shell, blades and bolts; the impeller shell is formed by
welding an impeller ring, an impeller plate, a shaft sleeve, conical linings and a plurality of blade plates; the blade plates are uniformly distributed in the circumferential direction of the impeller ring, the two sides of each
blade plate are welded to the impeller ring and the impeller plate, and the projection of any
blade plate in the axial direction of the impeller is in a bent shape; each
blade plate is formed by combining an arc plate with astraight plate, wherein the straight plate portions of the blade plates are arranged in a radial
radiation shape, and the inner sides of arcs of the arc plate portions are arranged in the rotation direction of the impeller. The structure has the beneficial effects that the aerodynamic characteristics of the impeller are optimized, the stirring effect on
airflow during high speed rotation of the impeller is reduced,
aerodynamics noise of air in the high-speed rotation impeller is lowered, and the operation
energy consumption is reduced; and the motion
tail of a fed wood
chip in the impeller isoptimized, friction when the wood
chip is attached to the blade plates to slide is reduced, abrasion of the blade plates is reduced, the situation that the wood
chip is broken by the blade plates isreduced, and the wood chip feeding efficiency of the impeller is improved.
