METHOD OF AND DEVICE FOR FIXING RATES OF POWER MATERIAL IN TRANSPORT MAIN LINE Russian patent published in 2005 - IPC

FIELD: materials handling facilities.

SUBSTANCE: invention relates to sphere of creation of fixing of rates of powder materials of different friability delivered for consumption at different ambient pressures. Method includes vibration of powder material in fill-in container insulated from ambient atmosphere, formation of suspension and delivery of suspension into transport main line. Suspension is formed by aeration of powder material by carrier gas in allotted volume of lower part of fill - in container separated by screen and is delivered into transport main line through jet. Rate of material is regulated by changing pressure of carrier gas in fill-in container or replacing jet with jet of other flow area. Suspension delivery into transport main line is cut off by discharge of carrier gas pressure from fill-in container into transport main line. Device for implementing the method has vertical housing forming fill-in container with charge and discharge holes and branch pipe to supply gas, pressure regulator, transport main line connected with discharge hole, second branch pipe to supply gas into zone of aeration of powder material. Device includes channel with shutoff valve connecting gas supply branch pipe with transport main line, spill screen forming zone of aeration of powder material in lower part of fill-in container with discharge hole, housing with holes separating zone of aeration from upper part of fill-in container with charge hole, vibrator arranger in its lower part and movable attachment unit of housing upper part.

EFFECT: provision of continuous delivery of materials of different properties, possibility of quickly cut off delivery.
