FIELD: pneumatic transport. ^ SUBSTANCE: invention relates to pressure-type pneumatic plants designed for transportation of lump loads. Proposed pressure plant contains air blower, pressure pipeline, charging hopper and feeder to deliver load into pressure pipeline, and support for pressure pipeline. Pressure pipeline from side of air blower consists of one or several sections spring-loaded relative to support and connected with pressure pipeline by elastic branch pipes. Directed-action vibrators are installed on said sections of pipeline. Invention makes it possible to prevent blocking of pressure pipeline on initial section when transporting lump loads. ^ EFFECT: improved reliability and efficiency of pneumotransport plant at minimum dynamic head built by air blower. ^ 3 dwg |
