Embodiments Below, embodiments of the present invention will be described in detail based on FIGS. 1 to 14.

As shown in FIGS. 1 and 2, the holding device between the filter surfaces of the filter plate of the filter press according to this embodiment is a stock solution supply port 2 formed on the filter surface 2b of the filter plate 2.
While the holding member 1 is inserted into the filter surface 2,
b, 2b, and when the filter plates 2, . Thus, a predetermined gap is maintained between the filter surfaces 2b, 2b between the adjacent filter plates 2, 2.

The holding member 1 is made of a molded article of hard synthetic resin, for example polypropylene resin. Between the above-mentioned holding member 1 is not limited to the above-mentioned resin.
It may be made of hard rubber, polyethylene resin, polystyrene resin, or the like. In addition, the holding member 1 may be made of metal, but metal members may damage the filter cloth and the pressing membrane of the pressing filter plate, so it is preferable to use a hard synthetic resin rather than metal. is preferable.

The above-mentioned holding member 1 is formed by integrally fixing a pair of truncated conical protrusions 1a, 1a and a connecting band 1b serving as a connecting part that connects both the protrusions 1a, 1a. The connecting band 1b is inserted into the stock solution supply port 2a of the filter plate 2 and suspended around the stock solution supply port, and supports both the protrusions 1a, 1a on the filter plate 2. It is preferable that the height of each protrusion 1a is approximately the same as the height of the frame 2c surrounding the filtration surface 2b relative to the filtration surface 2b.

Therefore, according to the above configuration, one protrusion 1a of the holding member 1 and a part of the connecting band 1b are connected to the filter plate 2.
is inserted into the stock solution supply port 2a, and the connecting band 1b is hung at a predetermined location around the stock solution supply port, and both protrusions 1a are connected to both filter surfaces 2 of the filter bed of the filter plate 2.
It is suspended and supported on b and 2b. As a result, the filter plate 2,
..., 2, when the mold is closed, each of the protrusions 1a comes into contact with the filtering surface 2b of the adjacent filter plate 2, as shown in FIG.
〓 is formed between a predetermined interval corresponding to the height dimension of a.

According to the above embodiment, the holding member 1 is
After inserting one protrusion 1a and a part of the connecting band 1b into the stock solution supply port 2a of the filter plate 2, the connecting band 1b is inserted into both filter surfaces 2b, 2b around the stock solution supply port 2a of the filter bed. Since the protrusions 1a, 1a are suspended and supported, they can be easily attached to and detached from the filter plate 2. Therefore, if necessary, for example, depending on the filtration pressure, the holding member 1 can be moved to the filter plate 2 during the above period.
It can be removed from the holding member 1 or replaced with a holding member 1 having a different material, height dimension, shape, etc. of the protruding portion 1a. Further, since it is not necessary to directly form the spacer holding member 1 on the filter plate 2, the structure of the filter plate 2 is simplified and manufacturing becomes easier.
