PNEUMATIC FEEDER OF METALLIC POWDER MATERIALS Russian patent published in 1995 - IPC

Abstract SU 1651500 A1

FIELD: materials handling; pneumatic transportation of loose materials. SUBSTANCE: installation for pneumatic delivery of metallic powder material has reservoir 1 with discharge branch pipe 2, injector 4 communicating through outlet channel 6 with transportation pipeline 8 which has hole 9. Ratio of passage area of hole 9 to area of section of pipeline 8 is within the limits where S_hole passage area of hole; S_tr area of section of transportation pipeline; l_tr length of transportation pipeline; d_tr inner diameter of transportation pipeline. When gas is delivered to injector 4, material from reservoir 1 is sucked along branch pipe 2 into injector 4 and transported by gas flow along pipeline 8. Part of gas escapes through hole 9, thus decreasing resistance to material flow in pipeline 8 which increases efficiency of installation. EFFECT: increased efficiency of installation. 1 dwg
