ROTARY FEEDER WITH RECESS FOR PROTECTIVE BAFFLE AND SHEAR EDGE ASSEMBLY

摘要

According to an aspect of the invention, a rotary feeder for transferring comminuted fibrous material is provided having as components: a rotary feeder housing, having at least one inlet opening for receiving material (chips) and at least one opening for discharging material (chips), and an internal shear edge assembly adjacent the inlet; wherein a protective baffle (doctor blade) is adjacent to the shear edge assembly; a rotor, rotatably mounted with the rotary feeder housing and having pockets for accepting material introduced to the rotary feeder housing; and a power source which rotates the rotor in said housing; and wherein the rotary feeder housing has a recess along the length of the rotor in the inlet at an exit end of the inlet, the recess being of sufficient size to allow the shear edge assembly and doctor blade to sit within the recess.

主权项

1. A comminuted cellulosic fibrous material rotary feeder apparatus comprising:
a rotary feeder housing, having an inlet configured to receive comminuted cellulosic fibrous material and a discharge outlet configured to discharge comminuted cellulosic fibrous material; a rotor, rotatably mounted with the rotary feeder housing, the rotor having radially extending rotor blades defining a plurality of pockets between the rotor blades, wherein each pocket is configured to accept comminuted cellulosic fibrous material introduced to the rotary feeder housing; and wherein the rotary feeder housing has an inner wall defining a recess along a length of the rotor at an exit end of the inlet, and wherein a shear edge assembly comprising a shear edge block is disposed within the recess such that a back of the shear edge assembly engages the inner wall of the rotary feeder housing and a front of the shear edge assembly does not extend beyond the recess.
