Abstract: A device installation and methods for extracting dust during the transfer of pulverulent products from a first container to a second container, the combination of the first container and of the second container forming, with the dust extraction device, a closed containment volume with connection between the two containers. A hollow connector with a side wall between its two ends defines an external wall and an internal wall so that the connector is pierced with several inlet pipes connected to hoses fed with a stream of pressurized fluid and also pierced with at least one fluid discharge pipe. The pipes projecting from said external wall of the connectors and opening onto the internal wall via orifices allows fluid to be introduced, the orifices being oriented relative to one another in such a way as to cause the fluid to flow in a cyclone within the connector, carrying with it any pulverulent product that remains on the internal wall and/or upstream and/or downstream of said connector.

Abstract: The invention relates to a device (1) for extracting dust in the context of the transfer of pulverulent products from a first container (2) to a second container (3), the combination of the first container and of the second container forming, with the dust extraction device, a closed containment volume comprising, by way of means of connection between the two containers (2), (3), a hollow connector (10) having an open top end (11) and an open bottom end (12), comprising a side wall (13) between its two ends, said side wall (13) defining an external wall (14) and an internal wall (15), characterized in that said connector (10) is pierced with several inlet pipes (20) connected to hoses (40) fed with a stream of pressurized fluid and also pierced with at least one fluid discharge pipe (30), said pipes projecting from said external wall (14) of said connector (10), and opening onto said internal wall (15) via orifices (50) that allow the fluid to be introduced, said orifices (50) being oriented relative to one a
