FIELD: mechanical engineering; pneumatic transportation. ^ SUBSTANCE: proposed plant contains hopper, drum-type sluice feeder, material line, material separator and air duct to direct dust-laden air from material separator to dust trap. Plant is furnished with cross-flow fan with port made on base of scroll housing in zone of maximum air velocities and negative static pressure. Outlet branch pipe of drum-type sluice feeder is connected to said port to act onto material in fan housing by air jet and subsequent delivery of air and material along material line into material separator. Lower part of outer of housing of drum-type sluice feeder is directed along tangential line drawn through lower point of scroll housing port. ^ EFFECT: simplified design, reduced metal usage. ^ 1 dwg |
