Fluidized bed dry-method sorting device

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a fluidized bed dry separation device. Background technique [0002] At present, the domestic mineral processing industry mainly uses flotation for separation. Although the flotation method has a wide range of applications and strong applicability, various chemicals are used in flotation, and the discharged sewage causes great pollution to the environment, and the cost is high, there are many influencing factors, and the process requirements are high. However, dry separation uses air instead of water as the separation medium, thereby avoiding environmental pollution, and the cost of dry separation is low and the process is simple. Therefore, compared with traditional flotation, the biggest advantages of dry separation are low cost, simple process and less environmental pollution. [0003] In the prior art, the air holes of the dry separation bed are easily blocked by...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a fluidized bed dry sorting device, which solves or partially solves the problem that the wind holes of the dry sorting bed in the prior art are easily blocked by gangue, and the shape of the wind holes makes it difficult for the wind force to be evenly distributed in the air. The technical problems on the bed surface have achieved the technical effect of no blockage of the air holes, uniform and reasonable distribution of wind force, and improved separation accuracy.
