The Evestigation Of The Dry Coat Sorting System Based On Laser Detection Technology

Coal plays a very important role in China’s economic developmentprocess, and the PREPARATION way plays a tremendous role in the coalproduction process, because the traditional wet coal preparation causingserious environmental pollution. The present invention of Dry CoalCleaning has limitations on the promotion and usage of a large area,needing a new, efficient coal preparation method.The laser Dry Coal Cleaning System is an anhydrous, efficient,environmentally friendly dry coal preparation technology. Compared withthe dry coal preparation in practice, relying on the density of raw coal,Laser Dry Coal Cleaning uses the more advanced laser technology toachieve the separation of coal. The separation technology is moreefficient, faster, and has more broad application prospects anddevelopment prospects, while avoiding the waste of the medium.This paper studies the design of the overall institution of the laserdry coal processing system and selection of laser devices described, andfinally how the control center under the control of the pressure devicesorting gangue.1．The core of Laser Dry Coal Cleaning institutions is the conicaldispersion plate design, being ensure the coal monolayer whereabouts,but also to ensure the efficiency of the coal preparation. To meet thisrequirement in many programs, selected the optimal solution to meet thedesign requirements. In order to make the coal quickly fall from theconical dispersion plate to form a monolayer coal. Driven by the motor,the conical dispersion plate rotates. How the conical dispersion platefixed to ensure effective functioning of the whole organization is a majorproblem. Conical dispersion plate fixed to make the design to ensure theoperation of the institution as a whole, but also to guarantee the efficiencyof the laser dry sorter.2．The sorting gangue of the laser device is to use the laser on different elements of matter has its own unique form of expression todetect the composition of the gangue, but different from the use of laserdetection of coal composition determination test or online detection. Inthe paper, the use of laser devices to detect coal "waste rock" contentmethod in the system using a laser scanner on a quick scan of coal, thedata of the scanned formation of coal characteristics is quickly transferredto a computer system, and compared with the standards-gray scoreinherent in the computer system, which can be used to distinguish coaland waste rock, more than the standard the coal is processed as "wasterock". After being compared, the data is quickly transferred to the controlsystem, the computer-controlled high pressure spray gun whereabouts inthe waste rock hit, blowing away the whereabouts of the coal of the chute,into the whereabouts of the "gangue" Chute. Laser sorting on coal, andavoiding environmental pollution...
