Abstract

The invention relates to a hindered bed separator. The separator comprises a separator bed body (16), a feeding well (1) arranged at one side of the upper part of the separator bed body, an underflow collecting cone (11) at the bottom of the separator lathe bed, a clean coal overflow collecting tank (5) arranged at the upper part of the separator bed body and a control system, and is characterized in that a supersonic generator (2) is arranged below a feeding port of the feeding well (1); a plurality of inclined pipes (4) are arranged at the upper part of an inner cavity of the separator bed body in the equispaced manner, the lower pipe orifices of the inclined pipes are communicated with the inner cavity of the separator bed body, and the upper pipe orifices are communicated with the clean coal overflow collecting tank (5); a pipenet current distributor is paved in the cavity of the joint part of the separator bed body (16) and the underflow collecting cone (11); and a pulsating device is arranged on one side wall of the separator bed body for generating pulsating current.

Description

technical field [0001] The invention relates to coal preparation technology, in particular to a high-efficiency disturbance bed separator. Background technique [0002] With the improvement of coal mining mechanization and the increasingly "poor, fine, and miscellaneous" coal resources, the content of coarse slime in raw coal is increasing, and the traditional coal preparation process is becoming more and more refined. As the world's largest coal production and consumption country, China is in the process of transforming from a coal preparation power to a coal preparation power. Currently, the separation of coarse coal slime is one of the focuses of coal preparation technology. In 1997, Australia was the first to use a disturbed bed separator to treat coarse coal slime. Since the introduction of this technology in our country at the beginning of the 21st century, since this type of disturbed bed separator has only one adjustment parameter, the flow rate of the rising water,...
