A PIPE-TROUGH CONVEYOR FOR PNEUMATIC CONVEYING OF DUSTY MATERIALS

摘要

An invention subject-matter is a pipe-trough conveyor for pneumatic conveying of primarily pulverized dusty materials. A pipe-trough conveyor consists of a steel, plastics or ceramic plastics pipeline produced as a whole or built from separate segments depending on the length of the transportation route. The pipe-trough conveyor while transporting material consumes air which has been introduced into it during its pulverization in the silo and for transportation realization takes compressed air from outside in the amount giving a transportation concentration up to 460 kg of dusty material per 1 kg of consumed air in the case of horizontal transportation and up to 600 kg of dusty material per 1 kg of consumed air in the case of transportation inclined at an angle up to 5 DEG . A pipeline (1) of the pipe-trough conveyor consists of the range of segments (L1, L2, ..., Ln) tightly connected to each other by the known way and of the segment "Z" with a nozzle (3) for a dusty material delivery together with a segment "R" with a discharging nozzle (4). All along the pipeline a chamber (6) is tightly attached by means of a nozzle (8) to the compressed air tank. On the bottom part of the side wall longitudinally and alternately to the right and left side of the long axis of this half of the wall a pipeline (1) has slots (5).
