A sorting system for coal gangue

Abstract

The invention provides a coal gangue sorting system, which includes a driving structure, a feeding structure, a sealing structure, an aeration structure, a storage box and a storage structure; the use of the feeding structure facilitates the uniform addition of magnetite and magnetite to the inside of the storage box. Pyrite powder, at the same time, it is convenient to discharge the sulfur concentrate and pyrrhotite concentrate inside the storage box. There is a storage structure inside the storage box, which facilitates the movement of the storage structure through the drive structure, thereby avoiding the sulfur concentrate and magnetite The iron concentrate is deposited at the bottom of the storage box to promote the mixing of sulfur concentrate and pyrrhotite concentrate with the solution, which facilitates the flotation of the sulfur concentrate powder inside the storage box, and the use of the aeration structure inside the storage box , so that the movement effect of the storage structure is better, and at the same time, the aeration structure is convenient for uniformly aerating the inside of the storage box, and at the same time, the storage structure effectively prevents the clogging of the aeration structure, thereby improving the flotation quality.

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
