AIR VACUUM DEVICE FOR TRANSFER OF LOOSE MATERIALS WITH HIGH WEIGHT CONCENTRATION Russian patent published in 2014 - IPC B65G53/24 

FIELD: transport.

SUBSTANCE: invention relates to air transport, particularly, to air vacuum transfer of loose materials with high weight concentration. Proposed invention can be used in various branches of engineering, especially when it is necessary to execute processing procedures simultaneously with transfer. The device contains suction pipeline with loose material infeed unit which pipeline has vertical and horizontal sections and connected with loose material unloader. The loose material unloader is provided with floodgate and vacuum gauge and is connected with vacuum pump. This connection is implemented via two or more vacuum receivers connected with each other in parallel by air ducts with quick action valves so that at one side of receivers air ducts are connected with suction pipe of vacuum pump, and at the other side of receivers air ducts are connected with unloader.

EFFECT: invention permits to transfer loose material with high concentration over long pipelines.
