Pneumatic conveyor and dosing system as well as sanding plant with a jet pump for free-flowing material

摘要

A pneumatic conveyor device (100... 105) for coupling to a container (2) for free-flowing material is disclosed, which has a jet pump (4) with at least one intake channel leading away from the container (2) and opening into the jet pump (4). 7) and a supply air channel (8) leading away from the container (2) and leading to an outer surface of the pneumatic conveyor device (100..105). The at least one intake duct (7) and the at least one supply air duct (8) are oriented substantially identically in the area of the container (2) and are advantageously inclined at most by a maximum of 40 ° with respect to the vertical (z). In addition, a dosing system (110..112) with a container (2) and a coupled thereto pneumatic conveyor device (100..105) is specified. Furthermore, a use of the pneumatic conveyor device (100..105) or metering system (110..112) in a sanding system of a rail vehicle (17) is specified.
