MMC型火车用门式煤采样装置的研制

Research and Development of MMC Gate-type Coal Sampling Device for Locomotive Coal Transportation

为了解决火车运输商品煤的煤质检测存在的问题,通过机械化采样设备直接在运煤车上采集具有代表性的煤样进行品质检验。火车用门式煤采样装置采用螺旋钻取方法采集垂直断面的煤样,通过门架和小车沿车厢的纵向和横向行走实现定点和任意点的采样,保证采样具有代表性。该装置结构紧凑,工作流程短,工作效率高;采制样系统全密封,水分损失小,无粉尘污染,对控制电力生产成本,保证锅炉安全经济运行,保护环境起到重要的作用。

In order to solve the existing problems of the coal quality inspection and measurement in the locomotive commercial coal transportation, the mechanized coal sampling device could be vertically to collect the representative coal samples from coal wagons for coal quality inspection. The gate type coal sampling device for locomotive coal wagons would be vertically to collect the cross sectional coal samples with the screw rotary sampling method. The gate type frame and small car with the longitudinal and lateral walking along with the coal wagons could make a setting point and random coal sampling in order to ensure the coal samples with the representativeness. The equipment is compact in structure, short in the working procedure and high in working efficiency. The coal sampling and preparation sys- tems are fully sealed, the moisture lost is small and there is no dust pollution. The device would play very important role to control electric power cost, to ensure the safety and economic operation of the boilers and to protect the environment.
