来る装置を提案するものである。 Conventionally, as a sealing device for the stock solution supply port of a plate with a diaphragm, a sheet-shaped packing was pasted to the diaphragm around the stock solution supply port, or a cylindrical packing was inserted into the stock solution supply port and the flange was attached to the diaphragm. It was attached. However, when the undiluted solution was forced into the filter press and the diaphragm was compressed, the adhesive surface between the diaphragm and the packing peeled off and the sealing properties were lost, and the undiluted solution entered between the cloth and the plate with the diaphragm and suspended the liquid. It was making it muddy. And, in the case of sheet-like packing, there was a risk of it falling off. Further, in the case of a plate with a diaphragm having a structure in which a pair of diaphragms are fixed to a core plate, there is a risk that the undiluted solution may enter between the diaphragm and the core plate from the abutting portion of the diaphragm located at the undiluted solution supply port. Furthermore, when replacing worn gaskets, it is difficult to remove the gaskets because they are attached with adhesive, and in order to attach new gaskets, the removed surface must be polished before applying the gaskets. Moreover, the labor was troublesome. This invention eliminates the above-mentioned drawbacks and proposes a device that is easy to install and remove, and that provides a perfect seal.

かめることができる。 This device is constructed as described above, and the cylindrical portion 7 of the packing 6 is inserted into the stock solution supply port 6 of the plate 1 with a diaphragm, and the convex strip 5 is provided on the back side of the flange.
By fitting into the groove 4 of the diaphragm 3, the packing 6 can be easily attached to the plate 1 with a diaphragm. That is, in the conventional device, a gasket 6' as shown in FIG. However, as high-pressure water or compressed air is injected to repeatedly squeeze the undiluted solution, the gasket 6' peels off and the sealing performance deteriorates, resulting in suspension of the undiluted solution or intrusion of the undiluted solution between the diaphragm 3 and the core plate 10. However, in the present invention, since the concave groove 4 of the diaphragm 3 and the convex strip 5 of the packing 6 are fitted, there is no need to use an adhesive to prevent the diaphragm from slipping off. Then, when each plate 1, 11 is closed, the diaphragm 3 and packing 6 are sandwiched between the core plate 10 and the liquid supply tool 13, and a complete seal is achieved, and the undiluted solution is No intrusion occurs at all, and the packing 6 does not fall off. When the gasket 6 becomes worn and needs to be replaced, it is easy to remove and install because no adhesive is used, unlike in the past, and there is no need to repair the mounting surface. As shown in FIG. 1, if a stepped portion 9 is provided on the diaphragm 3 around the undiluted solution supply port 2, the attached gasket 6 will be flush with the diaphragm 3, and the supply sandwiched between the plates 1 and 11 will be flush with the diaphragm 3. Dislocation of the liquid plate 13 can be prevented and sealing performance can be improved.
