摘要:
黑水虻生物转化猪粪后获得的有机肥含水率介于40%~60%之间,其黏结流动参数难以通过常规手段获取。为探究含水率对有机肥黏结流动的影响,通过堆积角测定与离散元仿真相结合的方法,从数值上量化分析不同含水率(41.21%~60.52%)对有机肥颗粒流动与黏结能力的影响。结果表明,有机肥-不锈钢碰撞恢复系数、有机肥-不锈钢静摩擦系数、有机肥JKR(Johnson-Kendall-Roberts)表面能显著影响有机肥堆积角;有机肥含水率在41.21%~60.52%范围内,随着含水率的增加,有机肥-不锈钢静摩擦系数先增大后减小,在含水率56.56%时达到最大值,为0.39,而JKR表面能由0.22 J·m-2逐渐升高到0.47 J·m-2;有机肥直剪试验表明,当含水率大于40%时,有机肥颗粒间的内摩擦角逐渐减小,但颗粒间的内聚力随JKR表面能增大而增大,有机肥颗粒间易发生团聚现象,一定程度上阻碍颗粒流动,堆积角增大。研究结果可为转移、输送有机肥的机械设备研究提供基础数据支撑。
