Device for conveying granular and/or powdery solid matters.

摘要

A conveying device for granular and/or powdery (pulverulent) solid materials such as plastics granules 34 or the like from a storage silo 33 or the like into a supply container 9 disposed upstream of a processing station, in particular the plastications barrel of the extruder of an injection moulding machine, in which device the storage silo 33 or the like is constantly connected to the supply container 9 via a hose line and/or pipeline 29. A compact design, which is not very susceptible to malfunction in operation, of the device is achieved in that one end 30 of the hose line and/or pipeline 29 is constantly immersed by means of a lance 32 - from above - in the solid materials 34 disposed in the storage silo 33 or the like, in that the second end 31 of the hose line and/or pipeline 29 opens out into the storage container 9, and in that this second end 31 of the hose line and/or pipeline has allocated to it a gas- or air-jet pump 24 to 28 which is connected to the supply container 9 above its supply space 12 with the interconnection of a filter 19.
