摘要
介绍了梅钢筒仓煤和焦炭取制样检测系统的设计方案及在线应用情况,系统实现了煤和焦炭的自动取样、焦炭不同粒级自动检测、焦炭机械强度检测、自动收集热反应试样、自动收集大于60 mm焦样、自动清理余料、现场无人值守和远程控制。该系统中焦炭机械强度测定过程中的配鼓精度较好,配鼓平均值为49.9 kg,标准偏差为0.2 kg。该系统为头部取样,取样代表性好,检测效率高,给外购焦炭质量控制及时提供了检测数据,同时改善了传统人工操作代表性差、劳动效率低等不足。
This paper introduces the design scheme and on-line application of the coal and coke sampling and preparation detection system in the silo of Meisteel.The system realizes the automatic sampling of coal and coke,the automatic detection of different particle sizes of coke,the detection of coke mechanical strength,the automatic collection of thermal reaction samples,the automatic collection of coke samples greater than 60 mm,the automatic cleaning of surplus materials,on-site unattended and remote control.In the system,the drum matching accuracy in the determination of coke mechanical strength is good.The average drum matching value is 49.9 kg and the standard deviation is 0.2 kg.The system is head sampling,with good sampling representativeness and high detection efficiency.It provides timely detection data for the quality control of purchased coke,and changes the problems of poor representativeness and low labor efficiency of traditional manual operation.
