摘　　要：带隔膜压榨装置的压滤机操作过程可分为过滤、压榨过滤、滤饼压密脱水3个阶段,在指导该类压滤机设计时,压榨脱水理论计算模型的准确性有待验证。利用厢式隔膜压滤机试验装置对超细重质碳酸钙悬浮液进行了不同试验条件下的固液分离试验,将对应时刻所得滤液量的试验值与理论值进行比较,3个阶段的最大相对误差分别为8.9%,8.4%,14%。The operational process of filter press with diaphragm device can be divided into three stages, the filtration, the press filtration, and the consolidation dewatering of press cake. In the design of such filter press, the accuracy of computational model＇ s squeeze dewatering theory should be further verified. Fine CaCO3 slurry as materiel, solid-liquid separation experiment under different conditions were carried out on chamber filter press with diaphragm device. Comparing the recorded filtrate data at the corresponding time with the theoretical data, the maximum relative error of three stages are 8.9%, 8.4%, 14%.
