The invention relates to a vibratory air dense media fluidized bed dry method sorting machine applicable to density grading on raw coal, ore and other materials within the particle size ranging from 6mm to 50mm. The sorting machine comprises a rack, supporting legs, a floating material discharging device, a sediment discharging device, a sediment discharging primary wind distribution chamber and a wind distribution pipe, wherein the floating material discharging device comprises a scraper blade chain wheel and a scraper blade chain; the sediment discharging device comprises a vibratory fluidized bed, the vibratory fluidized bed is internally provided with a secondary wind distribution chamber, an overall wind distribution plate is arranged above the secondary wind distribution chamber, the middle of the front side and rear side of the vibratory fluidized bed is symmetrically provided with a shock excitation motor, the four corners of the vibratory fluidized bed are provided with torsion springs hinged with the supporting legs; a barrel-type flexible connecting piece is arranged between the primary wind distribution chamber and the secondary wind distribution chamber; and an annular flexible connecting piece is arranged between the vibratory fluidized bed and the floating material discharging device. The sorting machine has the advantages of simple structure, high reliability, high throughput and capability of effectively avoiding damage caused by collision, friction and extrusion among the scraper blade, the material and the overall wind distribution plate.
Description
technical field [0001] The invention relates to a dry separation machine, in particular to a vibrating air dense medium fluidized bed dry separation machine suitable for density classification of raw coal, ore and other materials. Background technique [0002] At present, domestic dry separation equipment mainly includes air jigging shaker, air dense medium fluidized bed dry separation machine and compound dry separation machine. Among them, the air dense medium fluidized bed dry separator has a relatively complex structure, and the distance between its scraper chain and the overall air distribution plate is relatively close. When working, the force of the scraper chain will be applied to the material, and then transmitted to the overall air distribution plate, which will not only reduce the service life of the chain, but also cause serious damage to the overall air distribution plate. When the force is too large, the material will be pressed into the mesh of the integral a...
