AIR PRESSURE TRANSPORT PLANT Russian patent published in 2013 - IPC B65G53/04 

FIELD: transport.

SUBSTANCE: proposed plant comprises air blower, pressure pipeline, loading bin and feeder to supply cargo into pressure pipeline. Pressure pipeline consists of one or several plug-and-socket parts on blower side. Note here that arc-cross-section troughs are welded to said one or several parts with flange joints to make external bottom sections of said tube parts. Said troughs are connected via extra pipeline with gate to pressure pipeline adjoining air blower. Inner radii of curvature of trough R and pressure pipeline section R₀ are interrelated by relationship R=R₀+2δ, where δ is pressure pipeline wall thickness. Said external bottom sections of said tube parts confined by said trough is provided with holes. Sealed gate outlet tube is arranged at trough end section.

EFFECT: simplified design, lower costs.
