PRESSURE PNEUMATIC TRANSPORT PLANT Russian patent published in 2007 - IPC B65G53/40 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to pneumatic transportation of loose materials, namely, to plants with different length of material lines laid to place of destination. Proposed pressure pneumatic transport plant contains settling chambers with suction pipelines, each being equipped with pneumatic lift with input branch pipe and output pipeline, and hopper-accumulator to receive material from each settling chamber. Input branch pipe of pneumatic lift of each settling chamber is coupled with conical lower part of settling chamber, and output pipeline of pneumatic lift is coupled with cyclone-unloader. Exhaust branch pipe of cyclone is connected with upper part of settling chamber, and chute of each cyclone-unloader communicates, in its lower part, with jet feeder which is connected by corresponding main transport line with hopper-accumulator. Diameter of chute is equal to or is greater than diameter of input branch pipe of pneumatic lift, and height L of chute of cyclone-unloader and its diameter D_eq are at ratio L/ D_eq≤40.

EFFECT: enlarged technological capabilities of plant owing to increased distance of transportation of material between settling chambers and hopper-accumulator.
