MATERIAL HYDRAULIC TRANSPORTATION DEVICE Russian patent published in 1996 - IPC

FIELD: materials handling; hydraulic transportation of viscous-flow materials, for instance, dehydrated sediments of waste waters, coal pulp, manure, cement mortar. SUBSTANCE: installation has separate sections 1,2,3 and 4 of main pipeline, tubular feeders 5,6,7 and 8 accommodating liquid separators 9. Each feeder has gates 10. Viscous-flow material delivery system which feeds materials into feeder 5 has low-pressure pump 12. Suction branch pipe 13 of low-pressure pump 12 is connected with reservoir 14 containing material to be transported. Delivery branch pipe 15 is connected through charging valve 16 with end of feeder 5. Working liquid delivery system has high-pressure pump 17, whose suction branch pipe 18 is connected with working liquid source 19, and delivery branch pipe 20, with main pipelines 23 and 24. EFFECT: increased length of transportation of materials. 1 dwg
