) There is no rubber plate (4) interposed between the two. When filtration work is performed in this state, the uneven pressure generated within the filtration surface can be received by the protrusion (19) and the spacer +J' (10), and the uneven pressure is applied to the rubber plate (4). Because it does not cost at all,
There is no fear that the rubber plate (4) will break, and the spacer (10) is made of a hard material such as metal, so the press filter plate (1) can withstand long-term use. It is.

。Moreover, the cylindrical fitting part (9) is provided so as to be connected inward at a substantially right angle to the white part (4a) of the rubber plate (4), and furthermore, the cylindrical fitting part (9) has an engaging protrusion. Since the portion (9c) is provided so as to extend outward at a substantially right angle, the rubber plate (4
) The squeezing liquid that has entered the gap between the top wall of the mountain-shaped part (4a) and the top of the bulging part (7) flows into the cylindrical fitting part (9 ), the receiver is stopped and its pressure is significantly reduced, and the squeezed fluid also enters the gap between the outer surface of the cylindrical fitting part (9) and the circumferential wall of the recessed part (8). However, this is stopped by the engaging protrusion (9-C) arranged approximately perpendicular to the direction of intrusion of the squeezed liquid, so
The pressure is further reduced significantly. In this case, the tapered outer circumferential surface (23) of the spacing member (1o) contacts the tapered inner circumferential surface (24) of the cylindrical fitting portion (9) of the rubber plate (4) within the recessed portion (8). Because it is pressed strongly, it is possible to achieve an even more complete seal.
It is possible to completely prevent the squeezed liquid from entering, and there is no leakage of the squeezed liquid at all. Therefore, it is possible to reliably prevent the squeezed liquid from leaking during the press filtration operation, and the filtration operation can be carried out efficiently over a long period of time.

A cylindrical fitting part (9) of a size that fits into the top wall of the concave part (8) along the circumferential wall of the concave part (8) extends inward at a substantially right angle to the top wall of the mountain part (4a). The inner circumferential surface (24) of the cylindrical fitting part (9) is tapered so that the diameter becomes smaller toward the inside, and the tip of the cylindrical fitting part (9) is provided at a substantially right angle to the outside of the cylindrical fitting part (9). A series of engagement protrusions (9C) are provided, and each recess (8) includes a cylindrical fitting part (9) having the engagement protrusion (9C) and an inner end on the outer peripheral surface (23). A hard spacing member (10) with a tapered tapered surface is fitted, and the spacing members (10) on both sides of the substrate (3) are connected to each other, so that each spacing member (10) The tapered outer circumferential surface (23) is brought into pressure contact with the tapered inner circumferential surface (24) of the cylindrical fitting part (9), and the engagement protrusion (9c) is fitted into the engagement recess (lie), Since the outer end of the spacing member (10) is made to protrude a required height from the top surface of the bulge (7), the concave portion (
8), the tapered outer peripheral surface (23) of the spacing member (10) is connected to the tapered inner peripheral surface (23) of the cylindrical fitting part (9).
4), and the engaging protrusion (9C
) is fitted into the engaging recess (llc), thereby connecting the cylindrical fitting part (9) and the engaging convex part (9c) to the recessed part (llc).
) is securely sealed. Moreover, the rubber plate (4
) A cylindrical fitting part (9) is provided so as to be connected inward at a substantially right angle to the mountain-like part (4a) of the cylindrical fitting part (9).
), since the engaging convex portion (9C) is provided so as to extend outward at a substantially right angle, the convex portion (4a
) The squeezed fluid that has entered the gap between the top wall of the bulging portion (7) and the top of the bulging portion (7) is absorbed by the cylindrical fitting portion (9) and the engaging convex portion (9C).
), the pressure is significantly reduced, and the pressure between the tapered outer circumferential surface (23) of the spacing member (10) and the tapered inner circumferential surface of the cylindrical fitting part (9) is reduced. A complete seal can be achieved by strong pressure contact, so there is no fear of leakage of the squeezed liquid, and filtration work can be carried out efficiently over a long period of time. In addition, the number of bolts (12) and nuts (13) for attaching the spacing member (10) can be one each as shown in the embodiment, and the number of bolts (13) can be very small. This has the effect of reducing processing effort.
