带式压滤机传动系统建模与滤带滑移分析

将带式压滤机工作时所受的污泥载荷等效为外力矩加载至各辊筒上,建立带式压滤机传动系统旋转运动模型,给出稳态时滤带牵引张力和各辊筒旋转角位移以及张紧辊水平位移的数值计算方法,并引入滑移因子预测滑移现象的发生.分析研究稳态时驱动辊转速对滤带牵引张力的影响和张紧辊预载力、驱动辊转速对滑移因子的影响.建立的带式压滤机传动系统旋转运动模型可为带式压滤机传动系统的研究提供理论依据,对滤带滑移现象的分析可为带式压滤机传动系统设计提供参考.

Model construction of drive system of belt filter press and filter belt slipping analysis

n each roller. The steady-state tractive tensions were solved numerically, which of filter belts and rotational angular displacement of each roller and horizontal displacement of tensioner rollers. The slip factors were used to predict the onset of filter belts slipping on the rollers. The effects of the driving roller speed on the steady-state tractive tensions of filter belts were studied, and the effects of the preload of tensioner rollers and the driving roller speed on the steady-state slip factors were also analyzed. The rotational motion model of the drive system of belt filter press provide theoretical basis for further research. The belt slipping analysis were useful to the design of the drive system of belt filter press.
