METHOD AND DEVICE FOR GRAVIMETRIC DISPENSING OF POWDERY BULK MATERIAL Russian patent published in 2019 - IPC G01G11/08 

FIELD: physics.

SUBSTANCE: invention relates to devices for gravimetric dispensing of powdered loose material. Summary: device comprises storage container (20) containing loose material (2), feed pipe (24) for feeding loose material from container (20) for storage into dispensing container (22), metering device (26) for continuous removal of loose material from dispensing container (22) into outlet pipe (28) and further into discharge line. Dispensing container (22) is mounted on mass sensor (38). Supply pipe (24) is equipped with the first flexible tubular element, and outlet pipe (28) is equipped with the second flexible pipe element. First flexible tubular element contains first compensator (32) and second compensator (33) with rigid tubular element (34) located between them. Rigid tubular element (34) is fixed on mounting frame (40), which also supports with fixation dispensing container (22), discharge pipe (28) and discharge line.

EFFECT: technical result is higher accuracy of dosing powdered material.
