CHAMBER FEEDER OF POSITIVE-PRESSURE PNEUMATIC CONVEYING INSTALLATION Russian patent published in 2015 - IPC B65G53/40 

FIELD: transport.

SUBSTANCE: invention relates to pneumatic conveying, namely to discharging loose materials, e.g. alumina, cement and other corrosive dust-producing materials from flexible shell (package) using compressed gas. Chamber feeder of positive-pressure pneumatic conveying installation includes intake chamber for flexible package accommodation. Discharge pipeline is mounted on hinged cover. Pressure pipeline fitted in cover has fitting pipe with discharge nozzle with air intake holes and knife device for flexible package cutting. The air intake holes are directed towards package bottom, and sharp part of knife device is made outside air intake holes and in direction of articulated joint above the above mentioned cover. The fitting pipe with discharge nozzle is able to move freely under action of its own weight.

EFFECT: lower energy consumption for ejection of loose materials from flexible package, less dust in working areas, higher productivity and reliability of chamber feeder operation and providing integrity of flexible package bottom.
