FIELD: mechanical engineering; pneumatic transport. ^ SUBSTANCE: invention relates to devices for storing and transporting and it can be used at designing of transportation system using gas pressure. Proposed pneumatic conveyor has frame, compressor, separator, unloading device, suction pipeline, intake device, compressor main line, fixed part of delivery main line, movable part of delivery main line with matting device, rotary valve, jack to lift movable part of delivery main line and turning device. According to invention, vanes of rotary valve get into delivery main line. Fixed part of delivery main line before rotary valve has head to direct air from compressor to vanes of rotary valve. Rotary valve body is made for vertical displacement relative to fixed part of delivery main line and is connected with fixed of main line by means of movable members, and with separator, by means of bushing mating with inner surface of separator bushing through seal. ^ EFFECT: reduced resistance in delivery main line, increased efficiency of device, provision of adjustment of position of rotor valve vanes with resulting optimization of efficiency. ^ 5 cl, 7 dwg |
