摘要
概述了过滤机上采用压榨技术的重要意义。结合自动箱式及板框式压滤机的薄膜压榨技术,推导出一维恒压压榨脱水的数学模型及理论解。用Basic语言在IBMPC计算机上计算出理论平均压榨比与压榨时间(U_T(?)-√)的关系,并同实际情况作比较,其结果符合良好。
The importance to develope expression technique in filters is described. The mathematical model of filter cake of one dimentional dewatering by using membrance expression under constant pressure for automatic press filter of recessed plate or frame-plate type is derived and its theoretical solution is presented. The relation of theoretical value of average consolidation ratio calculated by the present model and the expression time is given by IBM-PC computer with BASIC programme and compared with experiment data The theoretical values are in good agreement with the experimental results.
