1、11、12压缩空气进口阀；13进水阀；14安全阀；15洗水进口阀；16滤浆进口阀；17滤液出口阀；18滤浆出口阀4 实验步骤4.1 将碳酸镁在储浆槽中加水配制成5.3的悬浮液作滤浆，并在启动空压机前不停地搅拌，防止固体沉淀；4.2 按板、框的钮数为123212321的顺序排列号板框过滤机。将滤布复在2号板框两侧，使其表面平整，然后用压紧螺杆压紧板和框；4.3 启动空气压缩机，第一次控制压力在0.06MPa;4.4 将计量筒放置在滤液出口出，记录液面的初始读数，准备好秒表；4.5 关闭洗水阀，打开滤液出口阀，开启滤浆进口旋塞，当有滤液连续流出时开始记录时间，计量筒中液面每上升3cm记录一次时间。

2、记录时两人用秒表同时间隔记录；4.6 当流出的滤液呈细线状流出时，则过滤已完毕，停止计时，关闭进口旋塞；4.7 关闭进水阀，滤液出口阀，开洗水进口阀进行洗涤。洗水从滤液出口处流出时开始计时，每上升3cm记录一次时间，记录两组数据即可。4.8 洗涤完毕后，关闭洗水进口阀等阀门，清洗滤布，重新安装，调节压力在0.16MPa，按上述操作再进行另一次实验。5 数据处理过滤机类型：板框过滤机滤框个数：8滤布种类：帆布滤框尺寸：170170mm过滤总面积S0.191m2滤浆名称：碳酸镁悬浮液 5.1%温度：26.2摄氏度表1 0.08MPa 实验原始数据记录表过滤压力0.08（MPa）表压A =0.191
