The invention relates to a
fluidized bed dry-method sorting device. The
fluidized bed dry-method sorting device comprises a sorting
bed, a vibrating component, an
air chamber and an air inlet
pipe. The sorting
bed comprises a
bed plate and a back plate, wherein the back plate is fixed to the side edge of the bed plate. The bed plate is provided with multiple air holes. The cross section of each air hole is in a horn shape. The vibrating component is fixed to the back plate. The
air chamber is of a box body structure, wherein one end of the box body structure is opened. The
air chamber comprises a base plate, a
front panel, a rear panel and two side plates, and the
front panel, the rear panel and the two side plates are fixedly connected with corresponding side edges of the base plate. The height of the rear panel is greater than that of the
front panel. The bed plate is fixed to the opened end of the air chamber and is perpendicular to the front panel, the rear panel and the two side plates. The base plate is inclined relative to the bed plate. An
air cavity is formed inside the air chamber. The rear panel is provided with an air inlet, wherein the air inlet communicates with the
air cavity. The air inlet
pipe is fixed to the air inlet. An
air channel of the air inlet
pipe is parallel with the bed plate. The air inlet pipe is connected with external air blowing equipment. By means of the
fluidized bed dry-method sorting device, it is guaranteed that the air holes are not blocked;
wind power is distributed uniformly and reasonably; and sorting precision is improved.
