Abstract

The utility model relates to a vibrating fluidized bed dry separation machine for self-generated medium, which is suitable for dry separation of coal, ore and other materials. Using sorting feeding to form self-generated medium in the vibrating fluidized bed to achieve layering according to density, the material is fluidized under the synergistic effect of the updraft and the exciting force, and the high-density material is continuously discharged from the sorting bed to reduce the sorting load Separation is achieved by relying only on the medium bed with a certain density formed when the feed particles are fluidized, without adding heavy substances from outside. The sorting machine includes a sorting bed, an air distribution chamber, a discharge device, an overflow adjustment device, a dust-removing air-inducing hood, an exciting motor, a spring, and a frame. Three sorting sections are used to realize the separation of three kinds of heavy products and light products with different densities. It does not need to add weight, the cost of sorting is low, and there is no built-in chain discharge device. It mainly relies on vibration, fluidized bed self-flow and changing bed inclination to realize material transmission. It has simple structure, stable operation and high reliability.
