CHAMBER FEEDER OF PNEUMATIC TRANSPORTATION PLANT Russian patent published in 2015 - IPC B65G53/40 B65G65/30 

FIELD: transport.

SUBSTANCE: invention relates to pneumatic transport, namely to discharging from flexible envelope (packing) loose materials, for instance alum earth, cement, coal dust and other dust-producing and corrosive materials, using compressed gas and can be used in metallurgy, machine building, chemical and construction industry, mining ventures and other industries connected with loose material processing. Chamber feeder includes inlet chamber with cover containing discharge pipeline, discharge pipeline. Above bottom of inlet chamber, disk with skirt is placed to form closed space which is additionally connected by air duct with discharge pipeline to implement free disk vertical motion under action of compressed air. The mentioned disk with skirt is provided with hole closed by reverse-flow valve. The disk is capable of free vertical motion under action of discharge pipeline compressed air up to stopping devices. Into bottom of inlet chamber, regulator is embedded for possibility to accept filled flexible packing of various heights.

EFFECT: invention provides simplification of emptied packing extraction from chamber feeder, as well as acceptance of filled with loose material packing of various heights.
