Abstract:
1. A device for pneumatic or hydraulic conveying of dusty, powdery or granular bulk material by a conveying medium in a conveyor line having an upper and a lower portion, the device comprising: an inner pipe within the conveyor line having a longitudinal axis and extending eccentrically and axially parallel to the conveyor line in the upper portion of the conveyor line, said inner pipe having a circular cross section and lower openings at axially spaced intervals; and flow resistance disks disposed within the inner pipe, said flow resistance disks each having a circumference which is at least partially defined as elliptical, each flow resistance disk being disposed in the area of an opening and attached to the inner wall of the inner pipe, said flow resistance disks each having an upstream and a downstream surface such that an outlet opening for the inner pipe into the conveyor line and an inlet opening from the conveyor line into the inner pipe for conveying medium are defined, said flow resistance disks each being in engagement with the inner wall of the inner pipe by their elliptical circumference, the upstream surface of the disks forming an angle (α) of <90° with respect to the longitudinal axis of the inner pipe and diverting the conveying medium to the outlet opening.
