Technical Problem
现有采样过程为操作人员爬上罐车顶部进料口，通过进料口插入采样枪采样，此类采样方法存在诸多弊端：1、根据现有要求需要往复多次携带采样枪爬上罐车采样，进一步增加采样难度及采样风险
Benefits of technology
[0007]相比于现有技术，本实用新型的有益效果为：通过采集装置、缓存装置及封装装置的依序布设且全封闭式的连接，实现样品的采集过程完全处于全封闭状态，无外溢喷粉可防粉料的浪费及扬尘污染等。其中通过控制所述第一控制阀、所述第二控制阀及所述第三控制阀的开闭以使滞留在所述三叉管道内的粉料吹至所述密封罐体，防止三叉管道在采样过程中出现管道堵塞等情况而无法采集到样品，或者说滞留的粉料不清空会干扰下一时段所采集样品的品质。其中通过控制所述第二控制阀、所述第四控制阀的开闭以使采集粉料卸货至密封罐体过程中的样品，并可通过采集时间的控制可实现卸货粉料在卸车初期、中期、末期等任一时段内样品的采集，不同时段内采集的样品可以真实反映卸货粉料的整体品质。
