Coarse coal powder permanent magnet dry type echelon magnetic extractor

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 ofthe 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 locateson 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 ofthe 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 invention patent relates to a permanent magnetic dry 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 caused by coal burning, domestic and foreign countries have conducted in-depth research on the upgrading of coal burning, desulfurization and ash reduction. To obtain high-quality, low-sulfur and low-ash coal, the coal must be finely pulverized so that the minerals in the coal are fully dissociated, and then sorted. However, due to the high energy consumption of coal grinding and subsequent storage , Transportation operations bring many problems, therefore, current coal preparation plants are not equipped with pulverized coal preparation operations. It is worth not...
