针对黑水虻虫沙难以收集的问题,结合虫沙机械物理性能,设计了一种双向螺旋虫沙收集装置,对装置的工作原理与结构参数进行了分析与计算。为了确定双向螺旋虫沙收集装置的工作性能并得到最佳的工作参数,以双向螺旋转速、排料螺旋转速、虫沙厚度为试验因素,以排料管单圈排料量和收集完成时间为评价指标,对含水率43.6%的虫沙进行单因素和多因素正交试验分析,确定了各工作参数的主次顺序。结果表明,影响单圈排料量因素的主次顺序为排料螺旋转速>虫沙厚度>双向螺旋转速,影响收集完成时间因素的主次顺序为虫沙厚度>排料螺旋转速>双向螺旋转速。多因素正交试验与方差显著性检验有较好的一致性,排料螺旋转...

Aiming at the poor collection of the Hermetia illucens insect sand, combining with mechanical and physical properties of insect sand, the bidirectional spiral collecting device was designed, and the working principle and structural parameters of the device were analyzed and calculated.In order to determine the working performance of the bidirectional spiral collecting device for H.illucens insect sand and get the optimum parameters, the bidirectional spiral speed, discharging spiral speed, insect sand thickness were taken as the testing factors, and single lap discharge and homework time were ...
