摘　　要：由于传统无人化验系统中的振动给料方式存在效率低下和样品粒度离析等问题,煤质无人化验系统的新型定量取样称量装置设计可通过精确控制取样体积以减少样品离析,从而提高取样的代表性、准确性及称量效率,以期减少人工干预与操作风险并提高整个化验流程的效率。剖析无人化验系统组成及其传统称量的缺陷,介绍定量取样称量装置的结构原理及技术方案,研究设计1种定量取样称量装置,分析该定量取样称量装置的优势并通过精确控制取样体积以显著提升取样的代表性、准确性和称量效率。煤质无人化验系统定量取样称量装置采用封闭结构设计,有效避免样品离析,称量准确率极高,通过集成吸尘装置可清理残留煤样、避免样品交叉污染与混样以及增强环保性能,从而提升无人化验系统的综合性能。Due to the low efficiency and sample particle size segregation of the vibration feeding method in traditional unmanned laboratory systems,the newly designed quantitative sampling and weighing device can precisely control the sampling volume to reduce sample segregation and improve the representativeness and accuracy of sampling as well as the weighing efficiency.This reduces the manual intervention and operational risks,and improves overall efficiency.By dissecting the composition of the coal intelligent analysis system and the defects of the traditional weighing method,this paper introduced the structural principle and technical solution of quantitative sampling and weighing device,designed a new quantitative sampling and weighing device and analyzed its advantages.The sampling representativeness,accuracy and weighing efficiency were significantly improved by precisely controlling the sampling volume.It uses a closed design to prevent sample segregation,achieve high weighing accuracy,and includes an integrated dust-removal device.This device cleans residual coal samples,avoids cross-contamination and sample mixing,and enhances environmental protection,improves the overall performance of the coal intelligent analysis system.
