摘　　要：分析间歇式双卧轴搅拌机弧形旋转门的结构及工作特点,建立卸料门处搅拌死区的理论简化数学模型,得到以搅拌叶片最大回转半径及中心距为常量的搅拌死区截面积与卸料宽度的条件方程组,借助MATLAB软件进行具体实例计算,得到卸料门宽度的合理取值范围,减小了搅拌死区体积,提高了搅拌质量,并为合理确定间歇式双卧轴搅拌机卸料宽度给出具有参考价值的理论依据。By analyzing the structure and operating feature of batch double horizontal shafts mixer's discharging door,the theoretical and simplified model of stirring dead zone of charging door is established,and the equation about sectional area of stirring dead zone and charging width on condition of constant maximum gyration radius and the constant center distance is got. With the help of MATLAB software,a rational value range of charging width B is got,which increases the volume of stirring dead zone and improves the stirring quality. Besides,a value and theoretical reference when selects a reasonable charging width for batch double horizontal shaft mixer is provided.
