摘要

摘要: 扑尘罩是潜孔钻机除尘系统的关键部件，对潜孔钻机的扑尘能力、扑尘效率以及工作可靠性有重要影响。基于对潜孔钻机扑尘罩流场与结构参数的分析，采用三维建模软件Pro/E建立扑尘罩的三维模型，并通过流体分析软件Workbench对扑尘罩内部流场进行分析计算。分析了扑尘罩筒体高度、筒体直径及排气管倾角对扑尘效果的影响规律，提出扑尘罩的优化设计方案，并对气固两相流进行模拟分析。研究结果表明：当扑尘罩筒体直径为350 mm时、增加扑尘罩筒体高度、增大排气管的倾角，可减少泄漏环口的泄漏，有利于扑尘罩的扑尘。

Abstract: Dust shield in down-the-hole(DTH)drill,as a key component of its dust abatement system,plays an important role in dust-sucking capability,cleaning efficiency and operation reliability. Based on the analysis of internal flow field and structural parameters of the dust shield in DTH drill and a three-dimensional model built with Pro/e software, the flow field of dust shield was calculated with workbench software. An improved design scheme was proposed after exploring the influence of different structural parameters on sucking effect. And gas-solid two-phase flow was simulated and analyzed. The results show that the increase of the cylinder height of the dust shield will reduce the leakage of the leakage collar and is conducive to the collection of dust. When the cylinder diameter is 350 mm it has a beneficial effect on the stability of the internal flow field. The greater the inclination of exhaust pipe is, the better the dust collection capability of the shield has.
