    • PROBLEM TO BE SOLVED: To provide a filter unit for an extruder system, a filter structure for an extruder system having the same type of the filter unit, and a related filter exchange device.SOLUTION: The filter unit (35) for an extruder system has an outside holder (36) which has a hollow cylindrical shape and defines an inner portion (42). A plurality of outside penetrated openings (45) are opened to the inner portion (42). An outside filter element (37) is arranged on the holder (36) in an area of the outside penetrated openings (45). An inside holder (38) having a plurality of inside penetrated openings (67 and 68) is arranged in the inner portion (42). An inside filter element (39) is arranged on the inside holder (38) in the area of the inside penetrated openings (67 and 68). A filter area corresponding to both the outside filter element (37) and the inside filter element (39) is provided using the filter unit (35) so that the low differential pressure of a plastic material melt to be filtrated is achieved.
    • 要解决的问题:为了提供挤出机系统的过滤器单元,具有相同类型的过滤单元的挤出机系统的过滤器结构以及相关的过滤器更换装置。 解决方案:用于挤出机系统的过滤器单元(35)具有外部保持器(36),其具有中空圆柱形形状并且限定内部部分(42)。 多个外部穿透开口(45)向内部(42)开口。 外部过滤元件(37)在外侧穿透开口(45)的区域中设置在保持器(36)上。 具有多个内部穿透开口(67和68)的内部保持器(38)布置在内部部分(42)中。 内侧过滤元件(39)在内侧贯通开口(67,68)的区域内配置在内侧保持架(38)上。 使用过滤器单元(35)设置与外部过滤元件(37)和内部过滤元件(39)对应的过滤器区域,从而实现要过滤的塑料材料熔融物的低压差。 版权所有(C)2013,JPO&INPIT
