ABSTRACT:
A system for transferring dry flowable material includes a substantially closed transfer vessel adapted to have particulate material drawn therein by a suction line during a fill cycle and discharge the material upon selective pressurizing of the vessel. A filter containment housing is integral with the pressure vessel and houses a filter element arrangement internally of the vessel to filter particulate material from air drawn to the suction line while optimizing the material capacity of the transfer vessel. Pneumatic pressure is introduced to the upper and lower ends of the transfer vessel to establish a predetermined pressure differential across a lower fluid pressure inlet, and provision is made to effect a dual action cleaning of the filter elements so as to maintain optimum efficiency. A bypass system is operative to maintain a predetermined design pressure within the vessel.
