Problems solved by technology

This method requires huge equipment, complex process and low sorting efficiency, causing serious environmental pollution
The dry separation method includes the use of drum crushing to take advantage of the different strengths of coal and gangue, or the use of dual-energy γ-ray projection recognition and sorting by taking advantage of the difference in light transmittance between the two. The former destroys the shape of the coal block and has a poor sorting rate. , the equipment is huge, the latter facilities are expensive, and there is radiation
In addition, the working environment of manual screening is harsh, the labor intensity is high, and it is easy to misselect and miss

Abstract

The present invention provides an apparatus and method for sorting coal and gangue, comprising a conveying line, a queuing mechanism, a camera shutter trigger, a measuring table and a sorting actuator. The queuing mechanism, the camera shutter trigger, the measuring table and the sorting actuator are sequentially arranged on the conveying line. Through the above-mentioned devices, the volume of the coal and the volume of gangue are obtained by utilizing the characteristics of different densities of the coal and the gangue and by combining the intelligent vision and the image processing algorithm. The mass is further obtained through a dynamic weighing sensor installed on the roll-on line, and the coal and the gangue are separated by utilizing the characteristics of different densities. Theapparatus and the method realize automatic screening of coal and gangue, reduce cost, improve screening precision, and avoid environmental pollution.

Description

technical field [0001] The invention belongs to the field of coal automation equipment, and in particular relates to an equipment and method for sorting coal and coal gangue. Background technique [0002] Coal gangue is solid waste discharged during coal production and processing. It is a rock with low carbon content and harder than coal. In order to improve the quality of coal, coal gangue sorting is an indispensable link in coal mine production. [0003] At present, coal gangue sorting mainly includes wet sorting method, dry sorting method and manual sorting method. The wet separation method includes the jigging method and the dense medium method, and its characteristic is to use the difference in density between coal and gangue, put the raw coal into the solution, and realize the separation of coal and gangue. This method requires huge equipment, complex process and low sorting efficiency, causing serious environmental pollution. The dry separation method includes the ...
