黑索今粉料安全、连续加料与计量装置

Research on Safely and Continuously Feeding and Metering Device of RDX Powders

为了解决黑索今粉料因流动性差而容易在料斗卸料口结拱,造成卸料口堵塞,使黑索今粉料连续化、自动化加料中断,影响计量精确性和安全性的问题,设计一种黑索今粉料安全、连续加料计量装置,利用粉体流动测试仪测试黑索今粉料的流动性参数。结果表明:该装置的合适料仓参数为料仓半顶角小于28.9°,料仓出料口直径大于168 mm;在利用该装置加料的过程中,黑索今粉料能均匀、稳定地从料仓流出,计量误差小于1.0%。

To solve the problem that continuously and automatically feeding of hexahydro-1,3,5-trinitro-1,3,5-triazine（RDX） powders was interrupted and imprecision as well as security of metering were affected by RDX powders with poor flowability and easily blocked in the bin, a safe and continuous feeding and metering device for RDX powders was designed. Flowability parameters of RDX powders were tested by a powder flow tester. The results show that the appropriate hopper parameters are that the half angle of hopper is less than 28.9° and the diameter of hopper outlet is larger than 168 mm. RDX powders can run out from the hopper stably and uniformly in the process of feeding by the device, and the measurement error is less than 1.0%.
