The degree of bending of each cloth 2 is adjusted by freely moving and adjusting the position of the cloth bending rod 10.

Each of the cloths 2 has one end fixed to the cloth fixing rod 12 below each of the boards 1, . . . A stock solution supply hole 2c is provided which communicates with the stock solution supply port 1f at the corner, and the periphery of the stock solution supply hole 2c is fixed to the lower corner of the board with a stock solution supply hole holding ring 3, so that when the stock solution is supplied, the stock solution is transferred to the cloth 2. The stock solution is supplied only between the front part 2a and the rear part 2b of the bent cloth 2 through the stock solution supply hole 2c of the cloth 2 without entering between the cloth 2 and the plate 1. The other end of the cloth 2 is locked to a cloth winding roller 14 below the plate 1, and is always urged to rotate in the cloth winding direction. The bent part of the cloth 2 is hung around the outer peripheral surface of the cloth hanging rod 9 so as to rotate the cloth hanging rod 9, and a pair of cloth bending rods 1 are provided below the cloth hanging rod 9.
0 and 10, and when the cloth 2 rotates the cloth hanging rod 9, the cloth 2 rotates each cloth bending rod 10 and guides the cloth 2 to move toward the opposing cloth front part 2a.
The rear part 2b of the cloth is forcibly bent in the direction approaching the rear part 2b of the cloth, so that the cake adhering to the rear part 2b of the cloth on the rising side is peeled off at the bent part. Therefore, one end of the piece of cloth 2 between adjacent plates 1 and 1 is fixed to the cloth fixing rod 12 below one of the plates 1, and the area around the stock solution supply hole near one end is fixed around the stock solution supply hole at the bottom of the plate. is fixed with a stock solution supply port ring 3, and a pair of cloth bending rods 10,
At 10, the front part 2a and rear part 2b of the cloth 2 are bent in the direction toward each other, and the cloth 2 is bent and suspended by the cloth hanging rod 9, and the other end is bent to the cloth guide rod 15 below the other plate 1. Then turn the cloth take-up roller 1
4 is placed in a locked state. At the raised position A of the cloth hanging rod 9, it is positioned above the plate 1 so as not to interfere with the tightening of the plate 1 when the plate 1 is closed, while at the lowered position B of the cloth hanging rod 9. Of the front and rear parts 2a and 2b of the bent cloth 2, the rear part 2b bends toward the front part 2a side, and the cloth hanging rod reaches a state where the rear part 2b of the cloth 2 can no longer be bent by the cloth hanging rod 9 using the stock solution supply port ring 3. 9 is lowered and the front portion 2a is wound around the cloth take-up roller 14.

According to the above configuration, it operates as follows.

That is, by moving the movable plate 20 forward, all the plates 1,
..., 1 to the front stand 17 side to close the frame, and then pass the stock solution supply port 1f of every other board 1 and the stock solution supply hole 2c of each cloth 2 to each board 1, 1.
The front and rear parts 2a of the cloth 2 bent and sandwiched between
2b by supplying the stock solution between the cloth front and rear parts 2a and 2b.
The liquid is passed through the liquid collection port 1 of each plate 1.
While collecting from e,..., 1e, the cake is left between the front and rear portions 2a and 2b of the cloth.

When one pass process is completed, the movable plate 20 is moved backward and the plates 1, . . . , 1 connected in order from the movable plate side by the connecting links 24, . The frame will be opened. When each board 1 is opened, each cloth 2 is attached to each board 1.
To prevent the cloth 2 from coming into contact with the plate 1 and being worn out even when the cloth 2 is run against the plate 1. At the same time as the plate 1 is opened, the cake falls naturally from the cloth 2 due to its own weight. On the other hand, since one end of each cloth 2 is fixed to one of the plates 1, most of the remaining cakes attached to the cloths 2 are attached to the connecting links 24,..., when the plates are opened.
24 forcibly restricting the intervals between the plates 1, . Next, the motor 23 is driven to rotate in one direction, the pair of drive shafts 21, 21 are rotated synchronously, and the take-up pulleys 6, 6 above each plate fitted to the drive shafts 21, 21 are rotated. , the wires 7, 7 are rewound and the cloth hanging rod 9 is lowered together with the hanging fittings 8, 8 between the plates 1, 1 while maintaining its posture along the horizontal direction. As a result, as shown in FIGS. 8 to 9, the cloth 2 travels while rotating the cloth hanging rod 9 due to the rotational force of the take-up roller 15 at the bottom of one of the plates 1, and the rear portion 2b of the cloth is rotated. The cloth rear part 2b begins to rise toward the cloth hanging rod side, and is guided by rotating the cloth bending rod 10 and is bent in a direction approaching the opposing cloth front part 2a.
The cake attached to b is dropped with its weight. The cloth 2 from which the cake has been peeled off and removed is placed on the cloth hanging rod 9
After changing the traveling direction from upward to downward while being guided by rotating the cloth bending rod 10, the other cloth bending rod 10
The rear part 2 is guided by rotating the rear part 2 and faces again.
After being refracted to the b side, it is further guided downward. The cloth 2 guided downward is bent into a U-shape by a cloth guide rod 15 and then wound onto a cloth take-up roller 14 supported at the bottom of the plate 1.
On the other hand, as the cloth 2 runs, the front part 2 of the cloth 2
When the front part 2a of the cloth bends and runs around the cloth guide rod 15, the cake adhering to the cloth 2a is peeled off from the cloth 2 and falls off by itself due to the cake's own weight, or the cake is peeled off from the cloth 2 as the cloth 2 runs. I get blown away. Therefore, most of the cake adhering to the front and rear parts 2a and 2b of the cloth 2 wound on the cloth take-up roller 14 has been peeled off. Each of the winding pulleys 6 is driven until the cloth hanging rod 9 is located at the lowered position B. When the cloth 2 is wound around the cloth winding roller 14 and the cloth hanging rod 9 is located at the lowered position B, the motor 23 is driven. , and the rotation of the take-up pulley 6 is stopped.

Next, after the cloth 2 is wound around the cloth take-up roller 14, the motor 23 is reversely driven to rotate the drive shafts 21 and 2.
1 is reversely rotated and each wire 7 is wound up by each winding pulley 6, each cloth hanging rod 9 is rotated by the running of the cloth 2 and moves up between the plates 1, 1, and the attachment of each cloth winding roller 14 is caused. While charging the winding roller 14 against the force, each cloth 2 is rewound from the cloth winding roller 14 as shown in FIGS. 9 to 8.
After the cloth 2 rotates the cloth bending rod 10, the cloth hanging rod 9, and the cloth bending rod 10 and guides the cloth 2, each cloth hanging rod 9 slips out from between the plates 1 and 1 and is positioned at the raised position A. Then, the driving of the motor 23 is stopped, and the rotation of each take-up pulley 6 is stopped, and the cake discharging process is completed to prepare for the next overstep. If necessary, the cloth 2 is cleaned by spraying cleaning water onto the cloth 2 from the cloth cleaning pipe 16 below the cloth take-up roller 14.

According to the above embodiment, since one piece of cloth 2 is bent and placed between the pair of plates 1, 1, the cloth winding roller 14 is only provided on every other plate 1, and the cloth winding roller 14 is provided on every other plate 1. There is no need to provide a roller 14, the number of cloth take-up rollers 14 is halved, and the number of cloths 2 between the plates 1 and 1 is only one, which reduces the number of steps by half compared to the conventional case of two cloths. 2, it is only necessary to remove every other cloth 2 from the cloth take-up rollers 14 arranged on the plate 1, and the replacement work involves removing the cloth 2 from the cloth take-up rollers 14 and the cloth hanging rod 9, and adjusting the tension of the cloth 2. It is sufficient to perform the work once between each of the boards 1 and 1. Therefore,
The number of cloth take-up rollers 14 is reduced by almost half, making the entire filter press less expensive, and the work of replacing the cloth 2 and adjusting the tension of the cloth 2 becomes simple. In addition, since one end of the cloth 2 is fixed to the plate 1, when the plate 1 is forced to stop due to the regulation of the opening frame interval when the plate frame is opened,
The vibration generated in the plate 1 can be transmitted to the cloth 2, and the peeling of the cake from the cloth 2 can be promoted. Also, the front and rear of the cloth that held the cake, 2
a, 2b are forcibly separated when the plate frame is opened, and the running directions of the opposing cloth front and rear portions 2a, 2b are different from each other, and a shearing force is applied to the cake, thereby promoting the peeling of the cake from the cloth 2. be able to. Furthermore, when the cloth rear part 2b travels toward the cloth hanging rod 9 and is bent by the cloth bending rod 10 due to the lowering of the cloth hanging rod 9, the cake is surely peeled off at the bending part and dropped or shaken by its own weight. In addition, when the front portion 2a of the cloth is lowered and travels with the cloth guide rod 15 bent in a U-shape, the cake can be reliably peeled off from the cloth 2 at the bent portion. The cake can be allowed to fall naturally due to its own weight, or the cake can be shaken off by running the cloth 2. In addition, each cloth bending rod 10 and cloth hanging rod 9 are rotated by the cloth 2 and guide the traveling of the cloth 2, so that the cloth 2 is smoothly guided by each rod portion,
Damage to the cloth 2 is reduced. Further, a well-known stock solution supply plate is suspended and supported on the cloth 2 so that the stock solution supply hole 2c of the cloth 2 and the stock solution supply port 1f of the plate 1 are aligned with each other when the board is closed, thereby sealing the space between the cloth 2 and the board 1. There is no need for this, and there is no denting of the cloth 2 or shaking when the cloth runs due to suspension support of the stock solution supply plate, and the life of the cloth 2 can be extended. Also,
Since one end of the cloth 2 is fixed to the plate 1, the cloth 2 is less likely to shift from the plate 1, and the cloth 2 becomes more stable.

Note that the present invention is not limited to the above-mentioned embodiments, and can be implemented in various other embodiments. For example, the cloth bending rod 10 may be attached to the hanging fitting 8 so as not to be rotatable. Further, instead of the cloth bending rod 10, a cake peeling scraper may be provided.

In addition, a pair of cloth guide rods 15, 15 below the plate
may be omitted to further simplify the cloth winding mechanism. In this case, it is necessary to equip every other plate 1 with a cake peeling rod. That is, in FIG. 10, the winding roller 14 of the plate 1 in the center in the figure winds up the cloths 2, 2 on the front and back of the plate 1, but the cloths 2, 2 on the back side of the plate 1, that is, on the right side of the plate 1 in the figure, The cake attached to the rear part 2b of the cloth 2 is peeled off by the cloth bending rod 10, and the cake attached to the rear part 2b of the cloth 2 is
The cake attached to the front part 2a of the cloth take-up roller 1
4 and is peeled off from the cloth 2 when it is wound around the roller 14, while the cloth 2 on the front side of the plate 1
That is, the cake adhering to the rear part 2b of the cloth 2 on the left side of the plate 1 in the figure is peeled off from the cloth 2 when the cloth 2 descends and is bent by the cake peeling rod 33 provided at the bottom of the plate 1. The cloth 2
The cake adhering to the front part 2a is peeled off using the cloth bending rod 10 in the same manner as described above.

Further, as shown in FIGS. 11 and 12, the take-up pulley 6 may be arranged separately from the plate 1 without being supported by the plate 1. That is, the support cylinder 5 is loosely fitted onto the drive shaft 21 above the plate so as to be movable in the axial direction, and the support cylinder 5 is rotatably equipped with a take-up pulley 6, and the adjacent support cylinders 5 are connected to each other by connecting links 30, ..., 30, and move back and forth along the drive shaft 21 in accordance with the back and forth movement of the plates 1, ..., 1,
When the plates are opened, the take-up pulley 6 may be positioned above between the plates 1, 1. In the same figure, the cleaning tube 16 is divided into two parts to form a pair of cleaning tubes 31, 31, and each end is pivotally connected so that each cleaning tube 31 can be rotated during cleaning so that the cleaning tube 31 can be rotated approximately horizontally. While cleaning the cloth 2 is performed while being located at the cleaning position, each cleaning pipe 31 may be located at a retracted position along the vertical direction when discharging a cake or the like. Further, as shown in FIGS. 11 and 12 above, each end of each cloth guide rod 14 is fitted into the long groove 13a of each bracket 13 at the bottom of the plate so as to be vertically movable relative to the bracket 13. Since the cloths 2, 2 placed before and after the plate 1 are wound up on one cloth winding roller 14, when the tension of the cloths 2, 2 before and behind the plate with respect to each cloth guide rod 15 is different, this Can be absorbed.

Moreover, although the case has been described in which the cloth 2 is arranged approximately in the vertical direction, the above embodiment can also be applied to a type of filter press in which the cloth 2 is arranged in the horizontal direction.

Effects of the Invention According to the above configuration, a piece of cloth is bent and placed between a pair of plates, one end of the cloth is locked to the cloth winding roller of one plate, and the other end is fixed to the cloth winding roller of one of the plates. Since the cloth is fixed to the lower part of the other board adjacent to the cloth, and the bent part of the cloth is suspended and supported by the cloth hanging rod, the cloth winding roller can be installed on each board by simply providing a cloth winding roller on every other board. The number of cloth take-up rollers is halved as there is no need to provide a cloth winding roller, and the number of cloths between the plates is only one, which reduces the labor by half compared to the conventional two cloths, and the filter press as a whole becomes inexpensive. Also, when replacing each cloth, it is only necessary to remove one cloth from the cloth take-up roller and cloth hanging rod between adjacent boards, and the work of replacing the cloth and adjusting the tension of the cloth is done once each between the boards. This makes these tasks easy. Also,
Since one end of the cloth is fixed to the board, when the board is forced to stop at a predetermined opening interval when the board is opened, the vibration generated in the board can be transmitted to the cloth, and the cloth It can promote peeling of the cake. In addition, the front and rear parts of the opposing cloth that sandwiched the cake are forcibly separated when the plate frame is opened, and the running directions of the opposing cloth front and back parts are different from each other, and shearing force is applied to the cake. It can promote peeling of the cake. In addition, since the other end of the cloth is fixed to the board, if the area around the stock solution supply hole of the cloth on this fixed side is fixed around the stock solution supply port of the board, the stock solution supply hole of the cloth and the stock solution supply port of the board can be connected. It is no longer necessary to hang and support the well-known solution supply plate on the cloth to seal the space between the cloth and the plate when the plate is closed, and there is no need to suspend and support the solution supply plate on the cloth, thereby reducing dents in the cloth or shaking when the cloth runs. There is no
It can extend the life of the cloth. Also, since one end of the cloth is fixed to the plate, the cloth is less likely to shift from the plate, making the cloth more stable.
