More Information
Summary:A rigid outer tube is provided, also an elastic inner tube of substantially smaller diameter. The inner tube is hermetically sealed at each of its ends to form a closed annular chamber between the inner elastic tube and the rigid outer tube. Communicating through the wall of both the outer and inner elastic tubes are relief and check valves w.r.t. the elastic inner tube to maintain the integrity of the annular chambers. The valves are connected to a secondary gas supply from which air under pressure is directed into the conduit to assist in the transport of the bulk material. The annular chambers are serially connected by bridging tubes passing from one section to the adjacent section, interconnecting each of the annular chambers in an outer parallel line to permit atmospheric air to move serially through them from one end of the transport conveyor to the other.
