摘要
Abstract
The fully automatic sample preparation equipment was one of the devices with the lowest usage rate in the intelligent acceptance system.Research on multiple fully automated sample preparation units had found that insuffi⁃cient adaptability to coal types and bias in moisture or ash content were the most critical factors affecting equipment performance.Two issues were analyzed and solutions were proposed:this paper analyzed the insufficient ability to handle wet and sticky coal,and proposed measures to deal with blockages in the crusher inlet,screen mesh,belt feeder,and other areas,analyzed the difficulty in processing large particle coal samples,it was recommended to add a sieve at the crusher of the sampling machine or add a first stage crushing at the sample preparation end,analyzed the problem of poor quality coal that cannot be processed and suggested manual handling.This paper also analyzed the issue of score bias and suggested establishing a regular inspection system,analyzed the issue of cross contamination and suggested optimizing the structure of the crusher and vibration device.The flushing of coal samples should be in⁃creased and regular comparative tests should be conducted.For power plants that will construct and implement intelli⁃gent fuel acceptance systems in the future,the above analysis could be used to analyze equipment problems,and im⁃provement can be done according to the above methods,therefore,the normal operation of equipment can be en⁃sured.关键词
