Claims (1)

[Claims for Utility Model Registration] (1) Squeezing plates 1, 1 with a squeezing membrane 2 attached to the surface of the plate body 3 and inflating the squeezing membrane 2 with a squeezing fluid supplied from a squeezing fluid supply passage 3j.
5, an overbed section 10a, an inclined section 10b disposed on the outside of the overbed section 10a, and an inclined section 10b.
and a frame portion 10c which is placed on the outside of the overbed portion 10a, and which are arranged alternately, and a pair of cloths 11, 11 are placed between the two plates 1, 15, 10. The above-mentioned pressing plate 1,
15 pressing membranes 2 are expanded to form the pressing plates 1, 1.
5 and the pair of cloths 11 between the plate 10,
In the filter press that squeezes the cake held in a chamber 13 formed between
a pressing part 2a disposed opposite to the pressing part 2a, and an inclined part 10b of the plate 10 located outside the pressing part 2a.
a protrusion 2b which is disposed opposite to the plate body 3 and protrudes in a U-shaped cross section;
b, and a mounting portion 2c disposed opposite the frame portion 10c of the plate 10 and attached to the plate body 3, and the plate body 3 of the compression plate 1, 15 has a surface is provided with a recess 3b into which the protruding part 2b of the compressed membrane 2 is removably fitted, and the opening of the compressed fluid supply passage 3j is made to face the protruding part 2b of the compressed membrane 2; A liquid recovery guide member 9 that opens liquid recovery ports 9a and 9b to the chamber side for recovering the liquid flowing out when the cake is squeezed is fixed to a predetermined location of the attachment part 2c near the protrusion of the cake. At the time of over-squeezing, by supplying the squeezing fluid between the plate main body 3 and the squeezing membrane 2 through the opening, the protrusion 2b of the squeezing membrane 2 comes out of the recess 3b of the plate body 3, and the squeezing part 2
A filter press characterized in that a is moved substantially along the thickness direction of the plate main body 3 and toward the opposing plate 10 side. (2) The filter press according to claim 1, wherein the protruding portion 2b of the compressed membrane 2 is formed thinner than the compressed portion 2a. (3) The compressed membrane 2 has a stock solution supply port 2d in its compression section 2a, and forms an annular protrusion 2h that curves and protrudes in a U-shaped cross section toward the plate body around the stock solution supply port 2d. On the other hand, the plate main body 3 is provided with a stock solution supply through-hole 3d at a position corresponding to the stock solution supply port 2d of the compressed membrane 2, and the annular protrusion 2h is removably fitted around the through-hole 3d. The filter press according to claim 1 or 2, which is provided with an annular recess 3k. (4) Utility model registration claim No. 1, in which cutout recesses 14 and 16 are formed at the boundary between the outer side surface of the recess 3b of the plate main body 3 and the surface of the mounting portion 3c of the plate main body 3. The filter press according to any one of items 1 to 3.
