The other end of the R cloth 2 is locked to a filter cloth take-up roller 14 below the F plate I, and is always urged to rotate in the cloth winding direction. 'IPI2
The O3 bending part is arranged so that the F cloth hanging rod 9 is rotated around the outer peripheral surface of the F cloth hanging rod 9, and a pair of F cloth bending rods to, 10 are arranged below the cloth hanging rod 9. When the r cloth 2 rotates the t cloth hanging rod 9, the r cloth 2 rotates each f cloth bending rod 10 and guides the cloth 2 so that it moves in the direction approaching the opposing r right front section 2a. The rear part 2b is forcibly bent so that the cake attached to the right rear part 2b on the rising side is peeled off at the bent part. Therefore, one piece of f-cloth 2 between adjacent f-boards 1.1 has one end t below one f-board 1.
It is fixed to the cloth fixing rod 12, and the area around the undiluted solution supply type near one end is f
A stock solution supply roll 3 is fixed around the stock solution supply port on the upper part of the plate, and a pair of f cloth bending rods 10,
At 10, the front part 2a and rear part 2b of the f cloth 2 are bent in the direction toward each other, and the f cloth hanging rod 9 is bent and suspended, and the other end is attached to the f right inner rod below the other T plate ■. 15, and then placed in a state where it is locked to the cloth take-up roller 14. At the rising position A of the r-cloth hanging rod 9, it is positioned above the r-plate 1 so as not to interfere with the tightening of the t-plate I when the fil is closed, while the cloth hanging rod 9 is lowered. At position B, of the front and rear parts 2a and 2b of the bent f-cloth 2, the rear part 2b bends toward the front part 2a side, and the raw solution supply rolling ring 3
Then, the T-cloth hanging rod 9 is lowered to a state where the rear portion 2b of the T-cloth 2 can no longer be bent by the F-cloth hanging rod 9, and the front portion 2a is wound up by the F-cloth winding roller 14.

According to the above configuration, it operates as follows.

That is, after moving the movable plate 20 forward and tightening all the door plates 1° and I to the front stand ■7 side to close the frame, open the stock solution supply port I of each f plate 1 in the - position and each r cloth 2. P bent and sandwiched between the temporary 1.1 through the stock solution supply hole 2c.
The stock solution is supplied between the front and rear portions 2a and 2b of the cloth 2, and filtration is performed between the rear portions 2a and 2b of the P cloth surface, and the r liquid is sent to the filtrate collection ports 1e of each F plate 1, . . .

While collecting the cake from 1e, move it to the right front and rear part 2a.

Leave it between 2b.

When one filtration process is completed, the movable plate 20 is moved back and the connecting link 24. . . , 24, the T-plates 1, . When each r-plate l is closed, each r-cloth 2 is located apart from each f-plate l, and even if the f-cloth 2 is run against the f-plate l, the f cloth 2 will not reach the r-plate 1. Avoid contact and wear. At the same time as the frame of the f-plate l is closed, the cake naturally falls from the r-cloth 2 due to its own weight.

On the other hand, most of the remaining cake attached to r cloth 2 is @r
Since one end of the door cloth is fixed to one of the filters 1, the connecting link 24. ...,24te rtemporary I,...
By forcibly regulating the intervals between .

Next, the motor 23 is rotationally driven in one direction, the pair of drive shafts 21.21 are rotated synchronously, and the take-up pulleys 6.6 above each r plate fitted to the drive shafts 21.21 are rotated. hand,
The wire 7.7 is rewound and the filter cloth hanging rod 9 is lowered together with the hanging fittings 8, 8 between the door plates 1.1 while maintaining its posture along the horizontal direction. As a result, as shown in FIGS. 8 to 9, the f fabric 2 runs while rotating the f fabric hanging rod 9 due to the rotational biasing force of the take-up roller I5 at the bottom of one of the f temporary l, and f The right rear part 2b begins to rise toward the cloth hanging rod, and the right rear part 2b reaches t.
The cloth bending rod 10 is rotated and guided while being bent in a direction approaching the opposing right front part 2a, and the cake adhering to the f right rear part 2b is dropped with its heavy work at the bending part. The t cloth 2 from which the cake has been peeled off and removed is attached to the r cloth hanging rod 9.
After changing the traveling direction from upward to downward while being guided by rotating the F cloth bending rod 10, being guided by rotating the other f cloth bending rod 10, and being bent again toward the opposing rear 2b side, and then further You will be guided downward. The filter cloth 2 guided downward is bent into a U-shape by the t-right interior rod 15 and then wound up by a filter cloth take-up roller 14 supported at the lower part of the door plate 1. On the other hand, as the f-cloth 2 runs, the cake adhering to the front part 2a of the r-cloth 2 is peeled off from the r-cloth 2 when the f right front part 2a bends around the r-side rod 15 and runs. , the cake falls down due to its own weight, or is blown away from the r cloth 2 by the running of the layer 2.

Therefore, most of the cake adhering to the front and rear portions 2a and 2b of the cloth 2 being wound up on the cloth take-up roller 14 has been peeled off. Each of the winding pulleys 6 is driven until the r-cloth hanging rod 9 is located at the lowered position B, and when the f-cloth 2 is wound around the f-cloth winding roller 14 and the f-cloth hanging rod 9 is located at the lowered position B, The drive of the motor 23 is stopped, 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,
When the motor 23 is reversely driven to reversely rotate the drive shafts 21 and 21 and each wire 7 is wound up by each winding pulley 6, each r cloth hanging rod 9 is rotated by the running of the r cloth 2 and the door plate 1. 1
While charging the take-up roller 14 against the bias of each r-cloth winding roller 14, each r-cloth 2 rises between FIGS.
As shown in the figure, the filter cloth is unwound from the take-up roller 14,
After the r-cloth bending rod 1O1f cloth hanging rod 9 and the t-cloth bending rod 10 are rotated by the f-cloth 2 to guide the r-cloth 2,
When each f cloth hanging rod 9 comes out from between the door plates 1 and 1 and is located at the raised position A, 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. Prepare for the next filtration step. If necessary, the cloth 2 is washed by spraying washing 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 P cloth 2 is bent and placed between a pair of filter plates 1.1, each I plate can be There is no need to provide a filter cloth take-up roller 14 for each filter cloth, the number of R cloth take-up rollers 14 is halved, and the number of T cloths 2 between the door plates 1 and 1 is reduced to one (instead of the conventional two filter cloths). The number of steps is halved compared to the case of
When replacing each f cloth 2, it is only necessary to remove the f layer cloth 2 from the f layer cloth winding roller 14 arranged on the T plate l every other time.
The replacement work of removing the cloth take-up roller 14 from the cloth sling 9 and the adjustment work of stretching the cloth 2 may be carried out once in each interval of P1.1. 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 f-cloth 2 becomes simpler. In addition, since one end of the f cloth 2 is fixed to the f plate l, when the filter plate l is regulated to a predetermined closing frame interval and forced to stop when the door frame is closed, the plate l
The vibrations generated can be transmitted to the T cloth 2, and the peeling of the cake of the R cloth 2 can be promoted. Also, the rear part of the r cloth that held the cake, 2a.

2b is forcibly separated when the door plate is closed, and the running directions of the opposing T fabric surfaces 2a and 2b are different from each other, and a shearing force is applied to the cake, thereby promoting the peeling of the cake from the R fabric 2. I can do it. In addition, when the I-right rear part 2b travels toward the f-cloth hanging rod 9 and is bent by the f-cloth bending rod 10 due to the descent of the f-cloth hanging rod 9, the cake is reliably peeled off at the bending portion, and the cake is reliably peeled off by its own weight. The dropped part can be swung away, and the right front part 2a
When the right indoor rod 15 is bent in a U-shape and travels, the cake can be reliably peeled off from the P cloth 2 at the bent portion, and the cake can be allowed to fall naturally due to its own weight.
Alternatively, the cake can be shaken off by running the cloth 2. In addition, since the @r cloth bending rod IO and the r cloth hanging rod 9 are rotated by the r cloth 2 and guide the traveling of the r cloth 2, the f cloth 2 is smoothly guided by each rod portion, and the r cloth 2
less likely to be damaged. In addition, a well-known stock solution supply plate for aligning the stock solution supply hole 2c of the r cloth 2 and the stock solution supply port If of the r plate l when the f board is closed and sealing the space between the r cloth 2 and the t plate 1 is installed in the r cloth. There is no need to suspend and support the stock solution supply plate 2, and there is no dent in the r cloth 2 or sway when the f cloth is running due to the hanging support of the stock solution supply plate, and the life of the f cloth 2 can be extended. In addition, since one end of f cloth 2 was fixed to f tentative 1, f cloth 2 was fixed to Pj
ti, is less likely to deviate from 1, and the r cloth 2 becomes more stable.

Note that the present invention is not limited to the above embodiments,
It can be implemented in various other ways. For example, the f-cloth bending rod 10 may be attached to the hanging fitting 8 so as not to be rotatable.

Further, a cake peeling scraper may be provided in place of the f-cloth bending rod lO.

Furthermore, the pair of f-right indoor rods 15, 15 at the rear and upper part of P may be omitted to further simplify the t-cloth winding mechanism. In this case, it is necessary to equip every other filter 1 with a cake peeling rod. That is, in FIG. 10, the T fabrics 2, 2 on the front and rear sides of the plate 1 are wound up on the winding roller 14 of the winding slope L in the central part in the figure, but the T fabrics 2, 2 on the front and rear sides of the plate I The cake attached to the rear part 2b of the t cloth 2 on the right side of the temporary I is the above r
While being peeled off by the cloth bending rod IO, the cake adhering to the front part 2a of the r cloth 2 is taken up by the r cloth winding roller 14, and when being wound around the roller 14, it is peeled off from the f cloth 2, The cake adhering to the filter cloth 2 on the front side of the f-plate l, that is, the rear part 2b of the filter cloth 2 on the left side of the r-plate l in the figure, is removed by the cake peeling rod 33 provided at the lower part of the r-tent when the t-cloth 2 is lowered. When the cake is peeled off from the T-cloth 2 when it is bent, the cake attached to the front portion 2a of the T-cloth 2 is peeled off by the T-cloth bending rod 10 in the same manner as described above.

Also, as shown in Fig. 11.12, the take-up pulley 6 is
It may be arranged separately from the r-plate 1 without being supported by the plate 1. That is, the support cylinder 5 is loosely fitted to the rear upper drive shaft 21 so as to be movable in the axial direction, and the support cylinder 5 is rotatably provided with a take-up pulley 6, and the adjacent support cylinders 5 are connected to each other by a link. 30, . . . , 30 are connected, and the plate 1.
. . , the take-up pulley 6 may be configured to move back and forth along the drive shaft 21 in accordance with the backward movement of the l, and to position the take-up pulley 6 above between the r plates 1.1 when the f plate is closed. good. In the figure, the cleaning tube 16 is partially divided into a pair of cleaning tubes 3I, 31.
It consists of a bracket, each end of which is pivoted to allow each cleaning tube 3 to be connected during cleaning.
1 is rotated and placed in a cleaning position along the approximately horizontal direction to perform cleaning work on the cloth 2, while each cleaning pipe 31 is placed in a retracted position along the vertical direction when discharging a cake, etc. Good luck. In addition, as shown in FIGS. 1+ and 12 above, each end of each P right indoor rod 14 is fitted into the long groove 13a of each bracket 13 in the temporary lower part of F, so that it can move freely up and down against the bracket 13. Since they are arranged so that they can move up and down, when winding up the cloth 2.2 placed on the front and rear of the plate 1 onto one filter cloth winding roller 1, the filter cloth 2 on the front and rear of the filter plate for each r-use inner rod I5 is moved. , 2 are different, this can be absorbed.

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

Effects of the Invention According to the above configuration, a piece of F cloth is bent and placed between a pair of T plates, one end of the R cloth is locked to the F cloth winding roller of one I plate, and the other end is fixed to the F cloth winding roller of one I plate. Since one of the above F is temporarily fixed to the upper part of the other adjacent T plate, and the bent part of the above R cloth is suspended and supported by the P cloth hanging rope, a filter cloth take-up roller is attached to every other P plate. It is not necessary to provide a filter cloth take-up roller for each P temporary, and the number of cloth take-up rollers can be halved, and the number of filter cloths between the plates can be reduced to one (2).
The labor required for this method is halved compared to using sheets of f cloth, and the filter press as a whole becomes less expensive. In addition, when replacing each cloth, it is sufficient to remove the T cloth from the R cloth take-up roller and the R cloth hanger for one F cloth between adjacent F plates, and perform the cloth replacement work and the stretching adjustment of the P cloth. It is only necessary to perform the steps 1-1 times for each f-plate, which simplifies these operations. In addition, since one end of the f-cloth is fixed to the r-plate, when the r-plate is closed, the vibrations generated in the plate are transferred to the f-cloth when the roller is forced to stop due to being regulated to a predetermined closing interval. can communicate,
r It is possible to accelerate the peeling of the cake from the cloth. Also,
When the filter plate is closed, the front and rear parts of the opposing r cloth that sandwiched the cake are forcibly separated, and the opposite r right front and rear parts run in different directions, and a shearing force is applied to the cake, causing the cloth to separate. It can promote the peeling of the cake from the surface. In addition, since the other end of the f cloth is fixed to the f temporary, if the area around the undiluted solution supply type of the filter cloth on this fixed side is fixed around the undiluted solution supply port of the FW, the undiluted solution supply hole of the cloth and the undiluted solution of the T plate can be fixed. It is no longer necessary to hang and support the well-known stock solution supply plate on the P cloth to seal the space between the F cloth and the R plate by aligning the supply port with the T plate when the frame is closed, and the f There are no dents in the cloth or shaking when the cloth runs, and the life of the cloth can be extended. Also, since one end of the r cloth is temporarily fixed, the r cloth is less likely to shift from the r plate.
r The fabric becomes more stable.
