摘要:
在固定式打磨台上进行高精细度的金属打磨已成为机械制造工艺中的重要环节。为改善某公司固定式打磨台的排风除尘效果,提出了2种优化方案。采用CFD-DPM相互耦合的数值模拟方法,对打磨过程中固定式打磨台上的粉尘质量浓度分布情况进行分析,并对原固定式打磨台及2种优化方案的固定式打磨台排风除尘效果进行对比研究。研究结果表明,原固定式打磨台的排风除尘效果较差,而2种优化方案都能在一定程度上降低打磨过程中的粉尘质量浓度。当排风孔数量增加到4个和5个(上2下3)时,排风除尘效果较佳。在此基础上,通过在固定式打磨台安装风幕,对比得出安装风幕的4个排风孔固定式打磨台的排风除尘效果最佳,其呼吸带高度粉尘质量浓度和最大粉尘质量浓度相比未安装风幕分别降低了99.88%和91.81%,值得在相关工业实践中推广使用。
Abstract:
The high-precision metal grinding on the fixed grinding table has become an essential part of the mechanical manufacturing process. In order to improve the effect of air exhaust and dust removal on the fixed grinding table in a company,two optimization schemes were put forward. The dust mass concentration distribution on the fixed grinding table during the grinding process was studied using the CFD-DPM coupled numerical simulation method. The air exhaust and dust removal effects of the original fixed grinding table and the two optimization schemes were compared and analyzed. The research findings show that the air exhaust and dust removal effect of the original fixed grinding table is poor,while both the two optimization schemes can reduce the dust mass concentration during the grinding process to a certain extent. The best air exhaust and dust removal effect is achieved when the number of air exhaust holes is increased to four and five(two on top and three at the bottom). A comparison was conducted by installing wind curtains on the fixed grinding table, revealing that the configuration with four air exhaust holes and wind curtains exhibited optimal air exhaust and dust removal performance. In comparison to the scenario without wind curtains,this configuration resulted in reductions of 99.88% and 91.81% in dust mass concentration for the breathing zone height and maximum dust mass concentration respectively. It is recommended to promote this solution in relevant industrial practices.
