Abstract

The present invention provides a coarse coal powder permanent magnet dry type echelon magnetic extractor. The magnetic extractor includes a main body machine frame, a drive wheel machine frame equipped with a drive conveyer band wheel on the machine frame body and a drove wheel machine frame equipped with a drove conveyer band wheel on the machine frame body which are set on left side and right side of the main body machine frame respectively; an echelon magnetic source is set on top of a steel plate table of the main body machine frame, a magnetic material receiving hopper is set on bottom of the steel plate table of the main body machine frame; an upper conveyor belt part of a sorting material conveyer band drove by the drive conveyer band wheel and the drove conveyer band wheel locates on right upper part of the echelon magnetic source, a down bend returning band part locates on right down part of the echelon magnetic source; a vibrating feed hopper is set on the machine frame on upper of the drove conveyer band wheel, a non-magnetic receiving material hopper is set on the machine frame on down part of the drive conveyer band wheel; a poly-magnetic dielectric is set on upper of the sorting material conveyer band located on upper part of the echelon magnetic source which can move front and back, right and left.

Description

technical field [0001] The patent of the present invention relates to a permanent magnet dry-type cascade magnetic separator for coarse coal powder. This kind of magnetic separator is especially suitable for dry separation of ground coarse coal powder, and can be widely used in energy, electric power, metallurgy, coal chemical industry and other fields. Background technique [0002] In order to solve a series of environmental problems brought about by coal combustion at home and abroad, in-depth research has been carried out on coal-fired upgrading, desulfurization and ash reduction. In order to obtain high-quality low-sulfur and low-ash coal, the coal must be finely pulverized so that the minerals in the coal can be fully dissociated, and then sorted, but due to the high energy consumption of coal grinding, and the subsequent storage , Transportation operations bring many problems, therefore, the current coal preparation plants are not equipped with coal powder preparation...
