Coal gangue sorting system

Abstract

The invention provides a coal gangue sorting system. The coal gangue sorting system comprises a driving structure, a feeding structure, a sealing structure, an aeration structure, a storage box and astorage structure. A charging structure is used so that magnetite and pyrrhotite powder can be conveniently and uniformly added into the storage box, meanwhile, sulfur concentrates and magnetic yellowiron concentrates in the storage box can be conveniently discharged, the storage structure is arranged in the storage box, the storage structure can be conveniently driven to move through the drivingstructure so that sulfur concentrate and magnetic yellow iron concentrate are prevented from being deposited at the bottom end of the storage box, the mixing of the sulfur concentrate, the magnetic yellow iron concentrate and the solution is promoted and sulfur concentrate powder in the storage box is floated conveniently, meanwhile, an aeration structure in the storage box is used so that the movement effect of the storage structure is better, the aeration structure facilitates uniform aeration of the interior of the storage box, the storage structure effectively prevents the aeration structure from being blocked, and thus the flotation quality is improved.

Description

technical field [0001] The invention relates to the field of coal gangue sorting, in particular to a coal gangue sorting system. Background technique [0002] Coal gangue is the largest solid waste resource in my country. Coal gangue is a rock that is co-deposited and mixed with coal during the coal-forming process. For high-sulfur coal gangue, the main components are pyrite and coal, while iron ore The sulfur content of sulfur plays a key role in the quality of ironmaking and steelmaking, and most of the iron ore in coal gangue is enriched in gangue washing. Therefore, the sorting of coal gangue has an irreplaceable role for later use . [0003] Both pyrrhotite and magnetite in the crude iron concentrate after magnetic separation are magnetic, and it is difficult to separate them by magnetic separation. When using flotation to magnetically separate magnetite and pyrrhotite , it is necessary to introduce a conduit inside the flotation cell to aerate the inside of the flotati...

Problems solved by technology

[0003] Both pyrrhotite and magnetite in the crude iron concentrate after magnetic separation are magnetic, and it is difficult to separate them by magnetic separation. When using flotation to magnetically separate magnetite and pyrrhotite , it is necessary to introduce a conduit inside the flotation cell to aerate the inside of the flotation cell, which will easily cause blockage of the conduit inside the flotation cell when used for a long time, and the magnetite inside the flotation cell during the flotation process and pyrrhotite are deposited inside the flotation tank, making the flotation quality poor. Therefore, a coal gangue separation system is proposed to solve the above problems
