Ejector hood
First Claim
1. An ejection hood apparatus, comprisinga transfer conduit including a downwardly concave control shell, the transfer conduit including an inlet end portion and an outlet end portion, the inlet end portion being configured to receive an upwardly directed transfer air stream including ejected material with at least a partially upward trajectory;
- anda hood defining an ejection chamber, the ejection chamber including a lower chamber portion and an upper chamber portion located above the lower chamber portion, the lower chamber portion including a chamber inlet for receiving the transfer air stream from the outlet end portion of the transfer conduit with at least a partially downward trajectory, the lower chamber portion further including a lower chamber outlet located lower than the chamber inlet, the hood including at least one air outlet passage communicated with the upper chamber portion for exhausting at least a portion of the transfer air stream;
wherein the chamber inlet is a laterally open chamber inlet.

Abstract
An ejection hood apparatus includes a transfer conduit and a hood. The transfer conduit includes a downwardly concave control shell. An inlet end portion of the transfer conduit receives an upwardly directed transfer air stream including ejected material with at least a partially upward trajectory. The hood defines an ejection chamber including a lower chamber portion and an upper chamber portion. The lower chamber portion receives the transfer air stream from an outlet end portion of the transfer conduit with at least a partially downward trajectory. The hood includes at least one air outlet passage communicated with the upper chamber portion for exhausting at least a portion of the transfer air stream.
