利用低角度X射线衍射、红外光谱、喇曼光谱及孔结构分析,研究了用铁盐水解法制备的铁层柱蒙脱石的结构与性质。所制得的铁层柱蒙脱石以介孔型层离结构为主,微孔型柱撑结构为辅。前者为蒙脱石片层与铁离子水解产生的聚合羟基铁簇合物堆垛而成的卡房状结构,与d值为6.4±1.0nm的X射线衍射宽峰相对应;微孔型柱撑结构则与d值约1.5nm的(001)衍射峰相对应。所合成的系列铁层柱蒙脱石中最大的比表面积和孔容分别为215.7m2/g和0.291mL/g。500℃热处理后,仍保存铁层柱蒙脱石的介孔结构。铁层柱蒙脱石富含阴离子(NO3-),并作为平衡铁水解聚合物正电荷的反离子而稳定存在,可为磷钨酸离子[PW12O40]3-所交换。铁层柱蒙脱石的新型结构和特殊性质在催化剂、载体与吸附剂等领域具新的应用前景。

清选系统是气吸式红枣收获机的重要组成部分,降低清选含杂率、损失率和破损率是实现红枣收获机械化的关键技术。利用枣、杂惯性和流体力学特性差异,设计了一种惯性气流式红枣清选系统,并对其关键部件及结构参数进行设计和分析。采用Fluent软件探明了该清选系统内气流运动形成的“∞”形旋流有利于枣、杂的清选。为获得清选系统最佳工作参数,以气流速度、调节板开度为试验因素,以含杂率、损失率和破损率为评价指标,设计二次正交旋转组合试验。建立试验因素与指标间的回归模型,采用多目标优化算法进行参数优化,确定清选系统最优参数组合:气流速度为32.0 m/s,调节板开度为3.4 cm。在该条件下开展验证试验,得到含杂率、损失率和破损率分别为1.38%、3.37%和0.60%,与优化参数相比分别增加了0.06、0.12、0.03个百分点。该清选系统满足枣、杂清选作业要求。

为确定新疆果园散体厩肥离散元仿真参数,采用仿真试验与物理试验相结合的方法,对散体厩肥的离散元参数进行标定。以不同参数组合下的堆积角为响应值,采用Pla.kett-Burma.试验对散体厩肥离散元仿真参数进行筛选,得到对堆积角影响显著的参数,即厩肥-厩肥恢复系数、厩肥-钢恢复系数、JKR表面能;通过Box-Behnken试验建立堆积角与显著性参数的二阶回归模型,并对其进行优化,得到显著性参数最优值,即厩肥-厩肥恢复系数为0.49、厩肥-钢恢复系数为0.34、JKR表面能为0.02 J/m^(2);将最优参数组合下仿真试验得到的堆积角与物理试验值进行对比,二者相对误差为2.73%。研究表明,标定的参数可靠,可为果园散体厩肥深施机械化过程仿真参数优化提供依据。

新疆棉花特殊的地膜栽培模式导致在机械采收过程中容易混入残留地膜(简称残膜),残膜的存在是降低机采籽棉质量等级的重要因素之一。为有效清除机采籽棉中混有的残膜,设计了网状滚筒和正压风力结合的分离设备,建立了分离对象的运动控制方程,借助离散相模型(DPm)对机采籽棉残膜分离机的籽棉与残膜的分离原理进行了分析,通过数学模型分析的籽棉运动轨迹和基于CFD仿真分析的籽棉运动轨迹阐释了残膜的整个分离过程,最后对分离机籽棉入口处流场速度进行了试验。结果表明,在保证分离效果的前提下,得到了籽棉在入口处最佳速度为4.5m/s。该文提出的分离原理和设计方案可以为具有类似特性差异的农产品分离提供理论依据和借鉴。
