A p-pronation stock solution supply type furnace plate having stock solution holes in the filtration surface may be used, and furnace plates 2/ and 2/ on both sides excluding the central door plate (normal oven plate) in Fig. 5 may be used. Furthermore, a type of pressing door plate different from the pressing door plate 2 shown in the center of FIG. 2 may be used. However, instead of the bolt 80, as shown in FIG. 6, a fastening screw 15 having a small-diameter rond portion 15a at one end and a threaded portion 15b at the other end may be used. Said Rondo part 15
3 tightly fits into the mounting hole 7C of the mounting plate 7 and fixes the fastening screw 15 to the mounting plate 7 by welding. Thread the thin ring 6 and tighten it with the nut 16, and tighten this nut 1-1.
6. A gap 9 is formed between the two thin rings 6, 6 by mutual butting of the rings 6 and 16.

Further, as shown in FIG. 7, a stud bolt 17 is used in place of the bolt 8, and one end threaded part 17a is screwed into the threaded hole 7d of the mounting plate 7, while the other end threaded part 17b is connected to the furnace cloth 4.
The thin ring 6 may be passed through and tightened with a nut 16, and the nuts 16 and 16 may butt against each other to form a gap 9 between the thin rings 6 and 6. Moreover, instead of the thin circular ring 6, as shown in FIGS. 8, 9, and 10, a thin plate 18 having a through hole 18a and similar to the mounting plate 7 and having a slightly smaller size may be used. In this way, the number of parts that do not require the elongated plate 10 is reduced, the gap 9 formed between the furnace cloths 4.4 is formed over a wide range, and the p chamber 14 between the furnace cloths 4.4 is formed in a wide range. It becomes easier to supply the stock solution to. Furthermore, instead of the bolt 8, a combination of a countersunk screw 19 and a nut 16 as shown in FIG. 10 may be used. This abutment of the nuts 16.16 forms a gap 9 between the two plates 118.18. Furthermore, by making the through holes 5a and '7a of the thin ring 6 and the mounting plate 7 smaller than the stock solution supply port 4a of the furnace cloth 4, the area around the stock solution supply port 4a of the furnace cloth 4 can be protected. , the flow rate of the stock solution can be adjusted.

Furthermore, if the through-hole 6a of the thin-walled ring 6 and the through-hole lower a of the mounting plate 7 can be gradually reduced in size from the raw solution supply side of the filter press toward the distal end thereof, the shape may be oval, etc. In addition, the circular ring may be divided in the radial direction to form a substantially circular ring when installed, and if the ring is extremely thin, a protrusion for inserting a bolt may be provided on the surface as appropriate. It may be formed to provide strength. Furthermore, the mounting plate may be of any shape as long as it can achieve the same effects as described above.

As is clear from the above description, according to the present invention, a thin plate having a through hole is provided on the opposing surface of the periphery of each stock solution supply port of a pair of furnace cloths sandwiched between adjacent furnace plates. The fastening members are in contact with each other, and the thin plates and the mounting plate having one through hole are sandwiched between the furnace cloth and tightened with the fastening members, and the fastening members protrude from the opposing surfaces of the thin plates when the door plate is tightened. A gap is provided between the thin plates facing each other by abutting the protruding parts of the undiluted liquid into the undiluted liquid hole in the door plate, the through hole in the mounting plate, the undiluted liquid supply port in the furnace cloth, and the through hole in the thin plate. Since the liquid is supplied between the pair of furnace cloths through the gap between the thin plates, the pair of opposing thin plates can be separated when the frame is opened, and the raw liquid is supplied between the thin plates. II5. Remaining in the gap and blocking the gap can be reliably prevented, the stock solution can be smoothly supplied into the furnace chamber, and the space between the furnace cloths II5. Since the + can be opened wide, repair and cleaning work can be easily performed, and the structure is also simple and assembly is easy. Further, according to the present invention, since the thin plate and the mounting plate are attached around the raw solution supply port of the furnace cloth, the through hole is reliably connected to the raw solution hole of the furnace plate and the thin plate and the mounting plate, and the mounting plate is connected to the furnace cloth. It can be firmly attached to the board. In addition, in the conventional stock solution supply plate, the thickness of the plate is thick because the liquid supply path is provided in the plate wall part, and therefore the plate itself is heavy and puts an excessive load on the furnace cloth.However, according to the present invention, both thin-walled plates Since the protrusions of the opposing fastening members of are butted against each other to form a gap,
The thin plate or mounting plate attached to the furnace cloth can be made thinner and lighter than the conventional stock solution supply plate, and overload can be prevented from being applied to the furnace cloth. Furthermore, according to the present invention, there is no restriction on the liquid supply path for supplying the stock solution into the furnace chamber, and the stock solution can be supplied from the through hole of the thin plate in any direction such as up, down, left, right, etc. around the through hole, so that It is possible to increase the rate of supply of stock solution into the room and improve production efficiency.

In addition, since the conventional stock solution supply plate had a liquid supply path inside it, it was necessary to improve the precision of the sheet metal body.However, according to the present invention, the mutual connection of the fastening members of the two thin plates facing each other has been improved. Since multiple gaps are formed by butting, it is only necessary to increase the accuracy of the fastening members and their attachment points, and manufacturing costs can be reduced.Furthermore, according to the present invention, thin plates and attachments are required for each furnace cloth. Since a plate or the like is attached, the movement of each furnace cloth is not obstructed and can be made smooth.
