摘要

对压榨压力大于过滤压力情况下的压榨过程进行了分析

校正了滤饼的蠕变效应

导出了压榨液压分布方程和压榨方程.应用压力传感器—电阻应变仪—光线示波器系统实测了压榨过程滤饼内液压分布

并测定了不同过滤压力和压榨压力下的压榨宏观数据.实验结果与理论方程吻合较好.

Abstract

The mechanism of compression of filter cake when the pressing pressure is greater than the filtering pressure is analysed in this paper. The equations of compression and hydraulic pressure distribution are derived in which the creep effect of cake is taken into consideration . The hydraulic pressure distribution in cake during filtration and compression is detected. The experiments were carried out under different pressing and filtering pressures

and the experiment data show good agreement with the equations developed.
