Impeller of ring flaker

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of wood shavings preparation, in particular to an impeller of a ring-type flaker. Background technique [0002] The ring flake machine is one of the host machines for shaving preparation in particleboard production. The impeller of the ring flake machine plays a very important role in the entire feeding and cutting feed system, mainly including: ①The impeller rotates to generate airflow in the Negative pressure is formed in the separator, which sucks the wood chips into the cutting chamber, which plays the role of air-assisted feeding; ②The wood chips entering the high-speed rotating impeller are forced to rotate and do centrifugal motion, and are scattered radially to the knife ring to play the role of feeding. Function; ③In the slicing mechanism composed of the impeller and the knife ring of the ring planer, the impeller forces the wood chips to rotate and perform centrifugal motion, and the centrifugal fo...
