Abstract:
1. A device for extracting dust comprising a means of connection between a first container and a second container, said means of connection comprising a hollow connector having an open top end and an open bottom end, comprising a side wall between its two ends, said side wall defining an external wall and an internal wall, wherein said connector is pierced with several fluid inlet pipes connected to hoses fed with a stream of pressurized fluid and said connector being also pierced with at least one fluid discharge pipe, said inlet and discharge pipes projecting from said external wall of said connector, and said inlet pipes opening onto said internal wall via inlet orifices that allow the fluid to be introduced, said inlet orifices being oriented relative to one another in such a way as to cause said fluid to flow in a cyclone within said connector, carrying with it any pulverulent product that remains on at least one part selected from the group consisting of the internal wall, upstream, and downstream of said connector; and said discharge pipe opening onto said internal wall via a discharge orifice located intermediate between said open top end and said open bottom end, thereby allowing the fluid carrying any pulverulent product to be discharged from the connector.
