Research on Development Trend and Optimization Design of Spray System of Shearer

分析了采煤机喷雾系统的喷雾机理,综合国内外对采煤机喷雾系统的研究现状,对喷雾装置的结构及主要性能参数进行了优化改进设计,通过将喷嘴口径与旋流芯中心孔直径的相互配合使用、对喷嘴安装角进行合理调节、喷雾扩散角设置为60°等措施,可有效提高喷雾装置降尘效果,改善作业环境。

In this paper,the spray mechanism of the spray system of the shearer is analyzed,and the structure and main performance parameters of the spraying device are optimized and designed by synthesizing the present research situation of the spray system of the shearer at home and abroad.By using the diameter of the nozzle and the diameter of the center hole of the swirl core,the installation angle of the nozzle is adjusted reasonably and the spray diffusion angle is set to 60°,which can effectively improve the dust control effect of the spray device and improve the working environment.
