  • Patent number: 11001459
    Abstract: A device (20) for distribution of solid particles (22) for loading a vessel with solid particles, comprising a solid particles feed hopper (21), a rotating member and a drive member for driving in rotation said rotating member about a rotation axis, and a set of at least one deflector element (25, 25?, 25?) carried by said rotating member and erected, or adapted to be erected, on rotation of the shaft, relative to the rotation axis, in which device the feed hopper defines a set of at least one opening (29) conformed in an asymmetric manner relative to the rotation axis, defining at most one plane of symmetry passing through the rotation axis.

  • Publication number: 20200215508
    Abstract: A device for distribution of solid particles for loading a vessel with solid particles, comprising: a solid particle feed hopper, a rotating member and a drive member coupled to said rotating member to drive in rotation said rotating member, a set of at least one deflector element, each deflector element extending in its longitudinal direction between a first end and a second end, and being carried by said rotating member at its first end, where, at least one deflector element of said set is rigid and mounted to pivot on the rotating member at its first end, the device further comprises remotely actuatable deployment means adapted to drive at least one deflector element mounted to pivot on the rotating member so as to cause it to pivot from a position for introduction into the vessel to an erected, particle deviation position independent of the rotation speed of the rotating member.
