The workability in attaching and removing the filter cloth 7, which is a consumable that needs to be replaced periodically, is improved.

  Further, since the conventional hanging metal fitting is configured to lock the filter cloth cored bar only at the circumferential groove, the filter cloth cored bar may easily slide in the circumferential groove and fall off the hanging metal fitting. . However, according to this embodiment, when the filter cloth 7 is raised and lowered, the circumferential groove 11a and the neck portion 11b of the lower filter cloth mandrel 11 are engaged with the engagement deep groove 32 and the engagement protrusion 33 of the hanging metal fitting 26 to slide. Because of the contact, frictional resistance acts not only on the circumferential groove 11 a but also on the entire neck portion 11 b, and the lower filter cloth core 11 may come off the hanging metal fitting 26 even if the filter cloth 7 swings when the filter cloth 7 is lifted or lowered. Absent.

  In addition, the conventional hanging metal fitting has a structure in which a groove and an opening for passing a filter cloth mandrel through the groove are provided on both side surfaces, and one filter cloth core is inserted into each groove. If the structure is such that two filter cloth cores are inserted into one groove of a hanging metal fitting having a simple structure, the hanging metal fitting cannot maintain the required strength. However, according to the present embodiment, the suspension metal fitting 26 having the above-described structure has a sufficient margin, and the two lower filter cloth cores 11 can be accommodated in the same engaging deep groove 32. The lower filter cloth metal core 11 thus made is difficult to drop off from the hanging metal fitting 26, and the risk of the lower filter cloth metal core 11 falling off is halved.

  In addition, according to the present embodiment, the distance L between the opening 35 of the engagement deep groove 32 and the lower filter cloth core 11 accommodated on the opening 35 side is longer than the looseness generated in the filter cloth. Since the deep groove 32 is formed, the filter cloth 7 is caught for some reason (for example, the liquid supply plate 12 provided on the filter cloth 7 is caught by the filter board 5 when the filter cloth 7 is raised (when the suspension fitting 26 is lowered). ), The suspension fitting 26 continues to descend, and the lower filter cloth core 11 in the suspension fitting 26 is lifted. It is possible to prevent the filter cloth 7 suspended between the filter plates 5 from falling off during traveling without being disengaged from the engagement deep groove 32. In addition, since the two lower filter cloth cores 11 are accommodated in one engagement deep groove 32, even if the engagement deep groove 32 is lengthened, the overall length of the hanging metal fitting 26 is not greatly increased. The distance L can be appropriately determined in consideration of the distance that the lower filter cloth core 11 may float (the filter cloth 7 is loosened).

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, A various deformation | transformation is possible.
