摘要
为了提高农业纤维物料螺旋式输送装置的输送性能,降低输送功耗,提高生产率,利用MATLAB软件对比功耗数学模型进行单变量优化分析,并结合试验验证了理论分析的一致性。试验结果表明:螺旋式输送装置输送性能最佳的取值范围是:喂入量30～70 kg/min、螺距300～355 mm、螺旋轴转速97～137 r/min。以比功耗作为输送性能评价指标,采用3因素3水平的Box-Benhnken响应面分析法进行参数优化试验,得到了影响比功耗各因素的主次顺序:喂入量、螺距、螺旋轴转速。以比功耗最小为优化目标,利用Design-expert的优化模块对试验结果进行分析,确定出各因素对指标影响的最佳参数组合:螺距335 mm、螺旋轴转速117 r/min、喂入量30 kg/min,输送性能优化后比优化前提高了8%,上述成果满足预期设计目标,可为螺旋式输送装置的参数优化和结构改进提供一定的参考和指导。
In order to improve the conveying performance of the agricultural fiber material spiral conveying device,reduce the transmission power consumption and increase the productivity,the MATLAB software was used to compare the power consumption mathematical model for univariate optimization analysis,and the consistency of theoretical analysis was verified by experiments. The results showed that the optimal range of conveying performance of the screw conveyor was feeding amount 30 ～ 70 kg/min,pitch 300 ～ 355 mm,screw shaft speed 97 ～ 137 r/min. Taking the specific power consumption as the evaluation index of transportation performance,the parameter optimization experiment was carried out by Box-Benhnken response surface analysis method with 3 factors and 3 levels. The main order of the factors affecting the specific power consumption was obtained: feed amount,pitch,screw shaft speed.With the minimum power consumption as the optimization goal,the optimization result of Design-expert was used to analyze the test results,and the optimal parameter combination of various factors on the index was determined: the pitch was 335 mm,the screw shaft speed was 117 r/min,and the feeding amount was 30 kg/min,the optimized conveying performance was 8 percentage points higher than that before optimization. Above results meet the expected design goals,which could provide some reference and guidance for parameter optimization and structural improvement of the screw conveyor.
