Conveyor line with bypass for pneumatic loose material transport

摘要

The conveyor line consists of a gas-tight outer tube and at least partly gas permeable, concentric inner tube for the loose material. The jacket space between the tubes is divided into communicating, longitudinal chambers by annular restrictions (7). The inner tube (2) comprises a gas permeable zone with at least one aperture (3) in spacings of twice to triple the tube inner dia., to which are coupled a sudden, annular gap-shaped restriction and a diffusor-type widening (6).
