US Patent 9643776 Device for conveying a fine-particle medium

The invention relates to a device for conveying a fine-particle medium, in particular a granulate, including a flexible receptacle for receiving the medium, a receiving fixture for fastening of the receptacle in the region of an upper end facing away from a base of the receptacle, and a suction apparatus, inserted from above into the receptacle, for sucking the medium out of the receptacle. The device further includes outside the receptacle, in its base region or its lateral region, an apparatus for acting on the receptacle for the purpose of its deformation. The device ensures that feed interruptions during the conveyance of the fine-particle medium are avoided so that the medium is kept in a conveyable state, whereby an undisturbed automated feed of the medium is secured.
