PNEUMATIC AND HYDRAULIC CONVEYING INSTALLATION FOR TRANSPORTING BULK MATERIALS

摘要

Pneumatic and hydraulic conveying installation for transporting pulverulent, powdered or granular bulk material, comprising a transport piping with an internal pipe (2) arranged therein, parallel to the axis and provided with inlet (4) and outlet (3) openings. In order to make the bulk material swire continuously through the transport piping so intensely that clogging due to plugs can not occur, but also in order to enable the dissolution of eventual plugs, there is provided to arrange into the internal pipe (2) between an outlet opening (3) and an inlet opening (4) a perpendicular disk (5) provided with at least one opening (6) which is preferably a circular hole made in the middle of the disk (5) or a slot (13). The disk (5) may be arranged excentrically between the outlet opening (3) and the inlet opening (4) and may be interchangeably secured into the internal pipe (2).
