摘要: 针对光电智能干选机在集装箱作业环境下经常出现喷嘴堵塞的问题,对喷吹系统结构进行优化,在保证喷嘴打击力的同时,使其能在集装箱密闭空间充斥大量粉尘、煤灰和煤泥的恶劣工作环境下正常运转。对比分析了直角型喷嘴和斜角型喷嘴两种喷吹系统优化结构,并对优化后的喷吹系统进行有限元仿真模拟及工业现场应用试验,结果表明:优化后的喷吹系统中斜角喷嘴产生的击打力区间更大、击打力更强、结构上更优,现场工业试验中分选效果良好,无堵塞现象。

Abstract: The optical intelligent dry coal separator is a dry coal separation equipment based on advanced imaging and artificial intelligence technology, mainly composed of material system, recognition system, and execution system[1]. In the environment of container operation, a large amount of dust, coal ash, and coal slurry can easily cause the nozzle of the dry coal separator to clog, resulting in a significant decrease in the striking force and seriously affecting the separation effect[2]. In response to this problem, this paper proposes an optimization method for the nozzle, which can ensure that the nozzle has sufficient striking force during separation and can be used normally in harsh working environments. After practical testing, the optimized nozzlesignificantly improved the striking force, improved the material separation recognition rate, and brought significant economic benefits.
