である。That is, in this conventional pressing apparatus, the cake produced after the press-fitting filtration is completed is further used for the diaphragm 1.
When squeezed with 5, the filter cloth 7 is pushed into the flow channel 14b of the filtrate of the rigid filtration bed, as shown in FIG.
Was blocked, the discharge of the filtrate was obstructed, and the filtrate separated at a break was absorbed by the filter cloth or cake by stopping the pressing, but in the present invention, such an adverse effect was solved. . Further, in the device according to the present invention, the filter cloth 7 is not pushed into the groove 14b of the filtration bed, wrinkles do not occur on the filter cloth, and the cake is on the flat filter cloth surface, so that the cake can be easily opened at the time of opening. Can be peeled off. In the above-described embodiment, the filter plate 1 is attached to the filter bed of the filter plate 3.
4 is provided so that the protrusion 14a is elastically deformed, but it goes without saying that the protrusion 14a may be directly provided on the filter plate 3. Further, in the experimental example, the filter cloth 7 was not pushed between the protrusions 15a of the diaphragm 15 in the example of pressing the cake, but the protrusions 15a provided on the surface of the diaphragm 15 should be elastically deformable. It is even more effective.
