LIQUIDDPASSAGE HOLE REINFORCEMENT PLATE ON A FILTER SURFACE FITTED PRESSURE SHEET IN A PRESSURE FILTER PLATE

摘要

PURPOSE:To maintain good filter performance at all times by the smooth discharge of filter liquid and prevent the occurrence of abnormal high pressure. CONSTITUTION:Cylindrical part 12a of reinforcement plate 12 is inserted into connecting hole 10a on sheet 10, which is connected to filter liquid discharge passage 9b of base plate 9. As a result, when sheet 10 caused a flow deformation, for example, liquid passage opening 10a would be protected by cylindrical part 12a from being narrowed. In this way, it is possible to maintain good filter performance with safety by smooth filter liquid discharge at all times.
