畜牧混合废弃物分选装置运行参数试验研究

为验证一种新型畜牧混合废弃物分选装置的功能并制定合理的运行参数，以混合物料含水率MC、进料流量Q、柔性物分离器转速Nr为试验参数，采用二次正交旋转组合试验设计，建立评价指标与试验参数之间的回归模型，并运用目标优化的方法对模型进行优化。研究结果表明，试验样机能够实现混合物组分的按类分选，试验因素组合为含水率87.8%，物料流量41.6 L/min，柔性物分离器转速64.5 r/min时可获得最高的柔性杂质分离率；在以上因素情况下，以沉降性杂质分离率及物料损失率作为评价指标，试验得出沉降性杂质分离器的最佳转速为6 r/min。研究为提高畜牧混合废弃物分选装置的分离性能及结构优化提供了依据。

Experiments on working parameters of separating equipment for stockbreeding mixed rejectamenta

In order to validate the function and optimize the working parameters of a new stockbreeding mixed rejectamenta separating machine, water ratio, feed rate and rotating speed of flexible sundries separating shaft were taken as the experiment parameters, the recursive model of flexible sundries separating rate was gotten by means of quadratic orthogonal rotation experimental design. Result showed that the equipment could separate the mixture by sundries sort rightly, and the best working parameters combination were water ratio at 87.8%, feed rate at 41.6 L/min, rotating speed at 64.5 r/min, and the suitable rotating speed of the sediment separating shaft taken by additional experiment was 6 r/min. The results can provide references for improving the performance of the separating equipment.
