针对黑水虻虫沙收集过程劳动强度大、作业效率低等问题,设计了一种并排式黑水虻虫沙双叶轮集料装置。首先,依据黑水虻幼虫生物转化畜禽粪便工艺特点,确定并排式双叶轮的外形尺寸;通过对并排式双叶轮工作机理和动力学分析,确定弧形叶轮片曲线与数量,并获得叶轮集料运动轨迹和方程;在此基础上,确定了影响其集料性能的主要因素,选取前进速度、叶轮倾角、叶轮转速为试验因素,以集料效率和集料均匀度变异系数为响应值分别进行单因素及三因素三水平二次回归正交试验。建立了响应面数学模型,分析各因素对集料性能的影响,利用Design-Expert软件对影响因素进行综合优化。试验结果表明,各因素对集料效率的...

Aiming at the problems of high labor intensity and low work efficiency in the process of black soldier fly (Hermetia illucens L.) sand collecting, a parallel double impeller collecting device for black soldier fly sand was designed. Firstly, the external dimensions of parallel double impeller were determined according to the agronomic requirements of black soldier fly larvae bio-transforming livestock and poultry manure. By analyzing the working mechanism and dynamics of the parallel double impeller, the curve and quantity of the arc-shaped imp...
