Study on the Air Exhaust and Dust Removal Effect of Fixed Grinding Table
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 of99.88％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.
