Abstract
A powder processing apparatus includes a vessel. The vessel has an interior chamber that includes top and bottom regions, and a gas outlet to the exterior of the vessel. A wall divides the bottom region into first and second sub-regions, with the top region extending above the wall. First and second porous plates divide the first and second sub-regions such that there are first and second manifold regions below the first and second porous plates. The first and second gas manifold regions include first and second gas inlets from the exterior of the vessel.
Claims8
A powder processing apparatus comprising:
- a vessel including,
- an interior chamber having top and bottom regions, and a gas outlet to the exterior of the vessel,
- a wall dividing the bottom region into first and second sub-regions, with the top region extending above the wall, wherein the interior chamber diverges from the first and second sub-regions of the bottom region to the top region such that the top region above the first and second sub-regions is wider than the first and second sub-regions of the bottom region, and wherein the wall is solid with respect to powder movement through the wall, wherein the first and second sub-regions are equal in size, and
- first and second porous plates dividing the first and second sub-regions such that there are first and second gas manifold regions below the first and second porous plates, the first and second gas manifold regions including first and second gas inlets from the exterior of the vessel.
