The application research of coal quality comprehensive online testing technology in coal washery of Fenghuangshan coal mine in Jincheng anthracite mining group
摘要
Abstract
Based on the process flow of coal washery of Fenghuangshan coal mine in Jincheng anthracite mining group,and the actual requirement of coal quality online analysis of slack coal(smaller than 13mm)on the belt,a coal quality online analyzing system which was combined with the mechanized sampling and sample preparation system was designed, this paper demonstrated the equipment constitution, performance parameters of equipment and system technological creative points of this coal quality online analysis system,at the same time,the systematic equipments such as online ash content analyzer, online moisture content analyzer,supplementary mechanized sampling and sample preparation system,electronic control systems and industrial television system were stressed, and the supplementary mechanized sampling and sample preparation system included the primary samplers,belt feeder,belt division machine,the rotary division machine,sample collection equipment and bucket elevator.This system merged the coal quality online analyzing function and mechanized sampling and sample preparation function,so that the coal quality stability of product warehouse could be ensured,meanwhile,the mechanized sampling and sample preparation of coal transportation belt could be realized,as well as the sample collection for analyzing and preservation. The actual application experience in the scene showed that,the coal quality comprehensive online testing technology played roles such as controlling commercial coal quality,improving sampling precision and eliminating the risk of sampling work,through appraisal,we could see that it could meet the requirements of national standards.关键词
