摘要

为了解决电厂燃煤人工制样存在的工作效率低

劳动强度大

工作环境差

有害人体健康

误差大影响样品的代表性等问题

设计了煤炭自动制样系统。通过留样质量、出料粒径、留样精密度及制样偏倚等性能试验

证明该系统精密度和偏倚达到了GB 474—2008和GB/T19494.3—2004规定的要求

其应用提高了样品制备的自动化程度

减少了制样过程人为因素的干扰。

Abstract

To solve the problems occurred during manual coal sample preparation

such as low work efficiency

high labor intensity

poor working environment

harmful to human beings and poor representativeness of the sample due to large error

the auto coal sample preparation system was designed.Performance tests like residue sample mass

fuel size

residue sample precision and sample preparation bias verified this system has met the requirements of GB/T 19494.3-2004 and GB 474-2008 on precision and bias.Its application not only improves the automation degree of sample preparation

but also reduces human disturbance factors in the sample preparation process.
