旋转压滤机单位过滤面积质量流量的试验研究

he filtrate mass flow, the last stage filtrate mass flow, the solid-state rate of sludge and the average solid density of the entering material suspending liquid per filter unit on the rotary filter-press was studied. Through measuring the time that fills some volume vessel, demarcated the filtrate mass flow, drew the functional relation curve of the filtrate mass flow and the last stage filtrate mass flow accounts for the filtrate mass flow proportion based on the time respectively, and then calculated the filtrate total amount in the entering filter pressing process. At the end of the filter pressing process, took sample from the sediment, dried it, got the rate of solid-state of it, and then calculated the average solid density of the entering material suspending liquid according to the principle of mass balance.
