Device for pneumatic or hydraulic conveying of dust-like, powdery or granular bulk material

摘要

Device for pneumatic or hydraulic conveying of dust-like, powdery or granular bulk material, with a supply line, an axially parallel, preferably eccentric inner tube of circular cross section in the feed line, which has openings in intervals and flow resistances in the inner tube in the form of disks in the region of the openings, the outside of the openings at the inner wall of the inner tube and a aufströmseitige and an outflow-side surface as a result of which outlet openings in the feed line and inlet openings in the inner tube, which are formed for the pumping medium, characterized in that the disks (5, 5a, 5b) in the area adjacent to the inner wall of the elliptical shape and the aufströmseitige surface with the axis (14) of the inner tube (2) an angle (α) of 90° and the incident flow to the outlet openings (20, 20a, 20b) which deflects towards.
