POWDERY MEDIUM PNEUMATIC TRANSPORT METHOD Russian patent published in 2012 - IPC B65G53/40 B65G53/04 

FIELD: transport.

SUBSTANCE: invention relates to power machine building. When powdery medium is transferred from bin to transmission pipeline via inlet valve powdery medium piston formation of design volume and density is created in transmission pipeline by means of affecting the powdery medium by at least one pneumatic impact of compressed air which volume is less than design volume of piston formation. At the same time, design air pressure is established in the first receiver. Compressed air is fed to transmission pipeline in the form of air-blast to act on powdery medium piston formation. After pneumatic impact on powdery medium from the first receiver, feed in transmission pipeline is performed sequentially from several receivers with interrupters of additional pneumatic impacts in the form of air-blasts created in boost sections of pipelines between each interrupter and transmission pipeline after the inlet valve has been closed, and time of sequential feed of additional pneumatic impacts is chosen less than time of powdery medium movement to transmission pipeline section.

EFFECT: invention provides increase in transportation range and longer life of pneumatic system units.
