Description

Technical Field

[0001] The utility model relates to the technical field of intelligent dry coal preparation, in particular to a clean coal de-medium screening device which is convenient for disassembling and assembling the screen. Background Art

[0002] Intelligent dry coal separation technology uses the different physical properties of coal and gangue to identify them through X-rays and then accurately separate them through a fast actuator. Under X-ray irradiation, coal and gangue have different imaging differences due to their different absorption of rays. The system identifies coal and gangue based on the imaging differences and sends signals to the execution system. The execution system changes the original movement trajectory of coal or gangue, thereby achieving efficient and accurate separation of coal and gangue.
