Abstract
A rotary feeder having a cylindrical casing having an upper inlet port and a lower outlet port in the vertical direction and a rotor disposed within said cylindrical casing and having a center axis being made eccentric with respect to a horizontal rotor driving shaft supported pivotally on the cylindrical casing, the rotor having further a plurality of blades provided in such that each tip of said blades is able to be in contact with the inner peripheral surface of the cylindrical casing in the vicinity of said upper inlet port or lower outlet port by pressure differential between an upstream passage and a downstream passage.
Claims9
A rotary feeder for conveying granular material that includes
- a casing having a horizontally disposed cylindrical opening therein,
- a vertically disposed upper inlet port in the casing for connecting the opening to a material supply hopper,
- a vertically disposed lower outlet port in the casing for discharging material from said casing,
- a floating rotor assembly rotatably contained in the casing opening said rotor assembly having radially extended blades for moving material from the inlet port to the outlet port,
- mounting means for supporting the rotor assembly in the casing so that the rotor assembly can move upwardly to place the blade tips in sliding contact against the wall of the casing opening on either side of the inlet port, and
- pressure means for producing a difference in pressure between the inlet and outlet ports such that the rotor assembly is moved upwardly toward the inlet port.
