Abstract

This gas distributor comprises at least one elongate crosspiece including two side walls, inclined on their upper parts, connected to one another in their respective upper parts and defining a gas circulation housing between them emerging downward. The gas distributor includes at least one reinforcing member arranged in the housing defined in the elongate crosspiece, the reinforcing member including a central vertical plate that extends longitudinally in said housing and at least one bracket fastened transversely between the central vertical plate and the side wall of the elongate crosspiece.

First claim

The invention claimed is:

1. A gas distributor for a powder packaging installation, comprising at least one elongate crosspiece including two side walls, inclined on their upper parts, connected to one another in their respective upper edges and defining a gas circulation housing between them emerging downward, wherein the gas distributor includes at least one reinforcing member arranged in the housing defined in the elongate crosspiece, the reinforcing member including a central vertical plate that extends longitudinally in said housing and at least one bracket fastened transversely between the central vertical plate and one of the side walls of the elongate crosspiece, wherein a side edge of the bracket is fastened on an inner surface of said one of the side walls defining the housing.

2. The gas distributor according to claim 1 , wherein the reinforcing member comprises a lower longitudinal plate that extends horizontally to close the housing downwardly.

3. The gas distributor according to claim 2 , wherein the lower longitudinal plate has at least one vertical through hole.

4. The gas distributor according to claim 1 , comprising two elongate crosspieces arranged crossed, each including a reinforcing member provided with a central vertical plate and at least one bracket.

5. The gas distributor according to claim 1 , comprising three elongate crosspieces arranged crossed, each including a reinforcing member provided with a central vertical plate and at least one bracket.

6. The gas distributor according to claim 1 , wherein the central vertical plate of the reinforcing member has a horizontal through hole.

7. The gas distributor according to claim 1 , wherein an upper edge of the central vertical plate is attached at a coupling between the inclined upper parts of the side walls.

8. The gas distributor according to claim 1 , wherein the central vertical plate defines two longitudinal and opposite compartments in the housing, the reinforcing member including at least one bracket in each compartment.

9. The gas distributor according to claim 8 , wherein the reinforcing member includes several brackets distributed in each compartment.

10. The gas distributor according to claim 1 , wherein the bracket includes a through passage, the surface area of which represents at least 15% of the total surface area of the bracket.

11. The gas distributor according to claim 1 , comprising a lower peripheral plate that extends horizontally on the periphery of a central aperture, the elongate crosspiece extending through the central aperture.

12. A powder conditioning installation, comprising:
an enclosure having at least one side wall that converges downward,
a gas distributor according to claim 1 , interposed in the enclosure, and
at least one gas intake pipe emerging in the housing of the elongate crosspiece.

13. A gas distributor for a powder packaging installation, comprising at least one elongate crosspiece including two side walls, inclined on their upper parts, connected to one another in their respective upper edges and defining a gas circulation housing between them emerging downward, wherein the gas distributor includes at least one reinforcing member arranged in the housing defined in the elongate crosspiece, the reinforcing member including a central vertical plate that extends longitudinally in said housing and at least one bracket fastened transversely between the central vertical plate and one of the side walls of the elongate crosspiece, wherein an upper edge of the central vertical plate is attached at a coupling between the inclined upper parts of the two side walls.
