PNEUMATIC FEEDER AND CONNECTING STRUCTURE OF TRANSPORTING PIPES Russian patent published in 2020 - IPC B65G53/46 

FIELD: transportation.

SUBSTANCE: invention relates to pneumatic transportation. Pneumatic feeder comprises central cylinder (2), upper flange (1), lower flange (4), impeller (3) and drive. In upper flange (1) there are at least two loading holes (14), number of unloading holes (41) and loading holes (14) is identical and unloading holes (41) and loading holes (14) are arranged in staggered order. In places on lower surface of said upper flange (4) located opposite unloading holes (41) there are box-shaped cavities (12) for gas distribution. Improved utilization of space in device, increased volume of material supply by separate device, method of blowing is changed, which increases intensity of blowing and concentration of blown gas flows by one feeder with identical diameter and reduces prime cost of device operation.

EFFECT: connecting structure of transporting pipes by changing the communication between pipelines for transportation provides not only traditional blowing of material with one feeder into one reactor, but also blowing material with one feeder into two reactors with provision of accuracy of flow of blown-in materials, which thus saves costs for users.
