AIR CONVEYOR FOR POWDER-LIKE MEDIUM Russian patent published in 2010 - IPC B65G53/04 B65G53/40 

FIELD: transport.

SUBSTANCE: invention relates to power machine building. Proposed conveyor comprises surplus air pressure source, receiver, solenoid valve with control pulse generator, pipe to feed air to transport pipeline end face, inlet branch pipe with seat on outlet, shutter and pipe to feed air to said shutter, all aforesaid components being arranged in casing. Proposed device comprises also at least one additional receiver with solenoid valve and auxiliary branch pipe. Transport conveyor has accelerating section that forms shock wave. There is a hole made on casing end face, opposite the shutter, that communicates via said auxiliary branch pipe with transport conveyor end face. Aforesaid casing is inclined to horizontal line at the angle of natural slope of powder-like medium to allow it to flow through auxiliary branch pipe into transport conveyor end face. Inlet end of the pipe that feeds air to shutter and solenoid valve outlet chamber of additional receiver are communicated with inlet end of accelerating section that forms shock wave.

EFFECT: increased conveying range and higher reliability.
