Definitions
- the present invention relates to a gas distributor for a powder conditioning installation, comprising at least one elongated cross-member having two side walls, inclined on their upper parts, connected to each other at their respective upper edges and defining between them a housing for circulation of gas opening down.
- Such a gas distributor is intended in particular to equip facilities for the packaging of solid particles in bulk or powders.
- the solid particles are, for example, granules of polyethylene or polypropylene.
- the powders are, for example, polyethylene or polypropylene powder.
- the powder intended to circulate in such an installation retains moisture or liquid hydrocarbons and tends to form agglomerates or even compact blocks, so that the flow of powder does not flow smoothly into the installation.
- hydrocarbons must be removed to ensure the quality of the final product.

- a side edge of the bracket is fixed on an inner surface of the side wall defining the housing;
- the central vertical plate defines two longitudinal compartments and opposite in the housing, the reinforcing member having at least one square in each compartment;
- the reinforcing member comprises a plurality of brackets distributed in each compartment;
- the square has a through passage whose surface is at least 15% of the total area of the square;
- a lower peripheral plate which extends horizontally around the periphery of a central lumen, the elongated cross member extending through the central lumen.
- the invention also relates to a powder packaging plant, comprising:
- a gas distributor as defined above interposed in the chamber, and - at least one gas supply duct opening into the housing of the elongate crossbar.
- FIG. 1 is a schematic view of a packaging installation comprising a gas distributor according to the invention
