Patent ID: 6945409

Claim:
A device for de-dusting a flow of particles, which is useful in association with a dense load unit, the dense load unit comprising a means for loading the flow of particles into a core enclosure ( 1 ) in a downward direction and at least one means ( 3 ) for rotatively dispersing the particles below the core, wherein the device for de-dusting comprises: at least one lower hollow chamber ( 9 ) containing multiple openings ( 10 ), the chamber being arranged such that, when the device is associated with the dense load unit, the chamber surrounds the outside of the core enclosure ( 1 ) at its lower end but above the bottom of the core enclosure at a distance which is less than 10 times the distance between the bottom of the core enclosure and the top of the dispersing means ( 3 ), calculated along a vertical plane, and such that the openings ( 10 ) face away from the core enclosure, at least one hollow collection and support tube ( 12 ) connected to the chamber ( 9 ), and at least one evacuating means ( 17 ) for evacuating the dust associated with the particles, comprising a means of storing the dust, connected to the collection and support tube ( 12 ), wherein the evacuating means is in evacuating communication with the hollow collection and support tube ( 12 ), and the hollow collection and support tube ( 12 ) is in evacuating communication with the hollow chamber ( 9 ), such that an evacuating effect can be achieved through the openings ( 10 ) of the chamber ( 9 ).
