Separation device for coal and waste rocks and separation method thereof

Abstract

The invention provides a separation device for coal and waste rocks. The separation device comprises a vibrating coal feeder, a conveying belt, a queuing device, an image sensor, an image collector, a microprocessor, an upper computer, a separation controller, a high-pressure spray gun, a coal briquette channel and a waste rock channel. Information of the image sensor is processed in real time through the microprocessor and then sent to the upper computer, image information preprocessing, feature extraction, soft measurement model establishing and separation signal outputting are carried out, separation signals are sent to the separation controller, raw coal naturally falls into the coal briquette channel, and the waste rocks fall into the waste rock channel through the high-pressure spray gun. The invention further provides a separation method. The separation device and the separation method have the advantages that the defects of a low recognition rate, heavy environmental pollution and the like existing in an existing coal and waste rock separation method are effectively overcome, the recognition rate of the separation method is high, the environmental pollution can be effectively lightened, the separation device is small in size, easy to install and maintain and low in cost, separation precision and the automation degree of the raw coal are greatly improved, and manual waste rock picking is replaced.

Description

technical field [0001] The invention relates to a detection device and a detection method, in particular to a coal and gangue separation device and a separation method thereof. Background technique [0002] Coal and gangue are solid powders associated with the coal mining process and separated during the sorting process. The coal and gangue separation methods at home and abroad mainly include wet coal preparation and dry coal preparation. The wet coal preparation process is complicated, the equipment is huge, and it needs a lot of water, drying, and slime water treatment. Dry coal preparation mainly includes fluidized bed dry separation, gamma ray, wind dry cleaning and so on. The fluidized bed dry method does not require water, the sorting range is wide, the equipment is easy to wear, and the environment is seriously polluted; the gamma method is sorted based on the attenuation of gamma rays when the material is transmitted, which has low efficiency, high power consumptio...
