Abstract

The invention relates to an intelligent coal gangue separating machine which comprises a raw coal feeding hopper, a screening device, a primary conveyer belt conveyor and a secondary conveyer belt conveyor, a coal gangue identifying mechanism and a coal gangue separating mechanism, wherein a sequencing mechanism is arranged on the primary conveyer belt conveyor, an aligning mechanism used for carrying raw coal blocks conveyed by the primary conveyer belt conveyor, the coal gangue identifying mechanism comprises a raw coal block volume measuring device, an industrial personal computer, a weighing platform and a feeding device; the industrial personal computer is respectively connected with the raw coal block volume measuring device, a PLC and the weighing platform, the PLC is connected with the feeding device, the feeding device is arranged between the tail part of the secondary conveyer belt conveyor and the weighing platform; the coal gangue separating mechanism is a mechanical executing mechanism used for separating coal gangue on the weighing platform. The intelligent coal gangue separating machine is high in separating efficiency, free from pollution and high in automaton degree, can be used for separating coal and coal gangue, and has a wide application prospect in other mineral separation fields.

Description

technical field [0001] The invention relates to the field of coal gangue sorting, in particular to an intelligent coal gangue identification and sorting device based on a density method. Background technique [0002] Coal gangue sorting is a coal pre-combustion treatment technology, which is an indispensable link in coal mine production and one of the effective methods to improve coal quality. At present, coal gangue sorting mainly includes wet sorting method, dry sorting method and manual sorting method. [0003] The wet separation method mainly includes the dense medium method and the jigging method. It uses the different densities of coal and gangue to put the raw coal into the solution, thereby realizing the layered separation of coal and gangue. The equipment used in this method is huge and the process is complicated. , Sorting efficiency is low and pollutes the environment; the dry separation method includes the use of different strengths of coal and gangue to use...

Problems solved by technology

[0003] The wet separation method mainly includes the dense medium method and the jigging method. It uses the different densities of coal and gangue to put the raw coal into the solution, thereby realizing the layered separation of coal and gangue. The equipment used in this method is huge and the process is complicated. , Sorting efficiency is low and pollutes the environment; the dry separation method includes the use of different strengths of coal and gangue to use drum crushing and the use of coal and gangue to use dual-energy γ-ray transmission to identify and sort due to the difference in light transmittance. The shape of coal is destroyed, the sorting rate is poor, and the equipment is huge. The latter equipment is expensive, the sorting efficiency is low, and there is radiation; in addition, manual gangue has disadvantages such as harsh working environment, high labor intensity, and easy misselection or missed selection.
