    • PROBLEM TO BE SOLVED: To provide a filter element structure capable of suppressing reduction in a filtering flow rate and a backwash-type filtration device equipped with the filter element structure.SOLUTION: There is provided a filter element structure 100 which is mounted on a reverse-washing-type filtration device W and used for filtering a fluid flowing through the device, and comprises a pair of filter elements 10 and a connecting tube 13 for connecting one of the filter elements 10 to the other of the filter elements 10. The filter elements 10 have a filter medium 11 formed in a hollow cylindrical shape whose both ends are penetrated, an upper lid part 12 for covering the upper end part of the filter medium 11 and upper holes 12a penetrating the upper lid part 12. One end of the connecting tube 13 is connected to one of the upper holes 12a and the other end of the connecting tube 13 is connected to the other of the upper holes 12a.
    • 要解决的问题:提供一种能够抑制过滤流量降低的过滤元件结构和配备有过滤器元件结构的反冲洗型过滤装置。解决方案:提供一种过滤元件结构100,其安装在反向 洗涤式过滤装置W,用于过滤流过装置的流体,并且包括一对过滤元件10和用于将过滤元件10中的一个连接到另一个过滤元件10的连接管13.过滤器 元件10具有形成为两端被中空的中空圆筒形状的过滤介质11,用于覆盖过滤介质11的上端部的上盖部12和穿过上盖部12的上孔12a。 连接管13连接到上孔12a中的一个,连接管13的另一端连接到另一个上孔12a。
