Abstract
A rotary feeder having a stationary, cylindrical housing having disposed therein a number of injection nozzles, and within which rotate a plurality of vanes about a central axis, wherein pairs of adjacent vanes of the plurality of vanes define wedge volumes, wherein the housing extends a width along the central axis, wherein each of the vanes has a length along the central axis, and wherein the injection nozzles are positioned across the width of the housing, such that a spray pattern of a gas injected via the number of injection nozzles spans substantially the entire length of the vanes.
Claims20
A rotary feeder comprising:
- a stationary, cylindrical housing having disposed therein a number of injection nozzles, and within which rotate a plurality of vanes about a central axis, wherein pairs of adjacent vanes of the plurality of vanes define wedge volumes, wherein the housing extends a width along the central axis, wherein each of the vanes has a length along the central axis, and wherein the injection nozzles are positioned across the width of the housing, such that a spray pattern of a gas injected via the number of injection nozzles spans substantially the entire length of the vanes, wherein each of the number of injection nozzles is fluidly connected with a gas source via a gas feed line.
A rotary feeder comprising:
- a stationary, cylindrical housing having disposed therein a number of injection nozzles, and within which rotate a plurality of vanes about a central axis, wherein the housing extends a width along the central axis, wherein each of the vanes has a length along the central axis, wherein the injection nozzles are positioned across the width of the housing, such that a spray pattern of a gas injected via the number of injection nozzles spans substantially the entire length of the vanes, wherein each of the number of injection nozzles is located at a position along a circumference of the housing that is in the range of from about 50° to about 170° from an inlet of the rotary feeder, along a direction of rotation of the plurality of vanes, and wherein each of the number of injection nozzles is fluidly connected with a gas source via a gas feed line.
The rotary feeder 14, wherein the length of each of the plurality of vanes is slightly less than the width of the housing along the central axis, such that the each of the plurality of vanes extends almost to the end walls of the housing and can rotate freely within the housing.
A rotary feeder comprising:
- a stationary, cylindrical housing having disposed therein a number of injection nozzles, and within which rotate a plurality of vanes about a central axis, wherein the housing extends a width along the central axis from end walls thereof, wherein each of the vanes extends a length along the central axis, wherein the length each of the plurality of vanes extends along the central axis is slightly less than the width of the housing along the central axis, such that the each of the plurality of vanes extends almost to the end walls of the housing and can rotate freely within the housing, wherein the injection nozzles are positioned across the width of the housing, such that a spray pattern of a gas injected via the number of injection nozzles spans substantially the entire length of the vanes, and wherein each of the number of injection nozzles is fluidly connected with a gas source via a gas feed line.
