Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to an improvement in a concentrate supply plate for a filter press.

Conventionally, in the case of a filter press, a stock solution supply plate is generally arranged between the pair of furnace cloths, and the stock solution supply plate is fixed by tightening the adjacent furnace plates, and the stock solution is supplied to the filter press. , the stock solution is distributed from the stock solution hole in the door plate through the punched opening formed in each furnace cloth to the one communication opening for stock solution supply on the stock solution supply plate, and further communicates downward from the stock solution supply opening [1]. There is a flow ripple in the stock solution supply hole, formed between l!j71r [
, and is designed to supply the furnace chamber.

By the way, the stock solution supply plate is fixed to the oven cloth by gluing, sewing, bolting, etc. so that it does not fall off even when the oven cloth is run during cleaning of the -1p cloth.

However, the mounting work 1 and 1 for fixing the stock solution supply plate to the furnace cloth is complicated, and the structure is also quite complex, as it requires bolts, bolt holes, R holes, etc. There were some drawbacks. Furthermore, if the raw solution supply plate is fixed to the furnace cloth as described above, it is difficult to remove it when performing repair work or replacing the furnace cloth. There is a problem in that unless the furnace cloth is removed from the furnace cloth, it is impossible to clean the furnace sludge that has accumulated inside the undiluted solution supply plate, or the slag that has accumulated around the undiluted solution supply plate and between the furnace cloth and the undiluted solution supply plate. In addition, in the past, the entire area around the raw solution hole in the furnace plate was sealed with the raw solution supply plate and the door plate, but since the raw solution supply plate was interposed between the door plates, the number of sealing points increased, and it was not always possible to ensure a secure seal. There was also the drawback that it was not possible.

The present invention has been made in view of the above considerations, and has a simple structure, does not allow F5 residue to accumulate inside, can be easily attached to and detached from the furnace cloth, and can be reliably installed in the specified position. It is an object of the present invention to provide a stock solution supply plate for a filter press that can be fixed in position and more reliably seal the area around the stock solution hole in the furnace plate.

Therefore, the stock solution supply plate of the filter press according to the present invention is interposed between a pair of furnace cloths arranged between the door plates, and the arcuate portion formed at the upper part of each plate material connected to each other by a connecting member is connected to the furnace cloth. The undiluted solution is sandwiched between the door plates along the T arc of the opening for distributing the undiluted solution, and the undiluted solution is supplied into the p chamber between the inner furnace plates through the gap formed between the two plates by the connecting member. It is a feature.

The present invention will be explained in detail below based on illustrated embodiments. As shown in FIGS. 1 and 2, the stock solution supply plate 1 is roughly composed of a pair of planarly symmetrical plates 2 (2a, 2b) and a connecting member, such as a connecting rod 3.

The plate material 2 is a comparatively thinner annular material with an arcuate portion 4 formed on the upper part, and the arcuate portion 4 is formed on the furnace cloth 5 so as to communicate with the undiluted solution hole in the door plate. It is curved along the lower arc of the punched opening 6 for distribution.

On the other hand, two connecting rods 3 are provided at each end of the plate material 2.
They are fixed in place by appropriate means such as welding to form an opening 15 between the two plates. A part of the stock solution flowing from the opening 6 of the F5 cloth 5 and penetrating above the two arcuate parts 4, 4 of the second plate passes through this gap 15 into the p chamber 16 formed between the furnace cloths. (paid R).

Next, the case where the stock solution supply plate 1 is attached to the furnace cloth 5 will be explained based on FIG. 3.

The stock solution supply plate 1 is attached to a pair of furnace cloths 5, 5, on which the stock solution supply plate 1 is interposed. ....

It is suspended at 8. The cord-like member 8 has one end attached to the furnace cloth 5.
While the other end is attached to the cloth 7 by sewing or adhesive, the other end is detachably attached to the cloth 7. Then, there are four connecting rods that connect the two plates.3. . . , 3, the upper two connecting rods 3, 3 are provided with cloths 7, 3 on both sides of the openings 6.6 of the furnace cloths 5, 5, respectively. ..., 7
String-like member 8. . . , 8 are wrapped around each other, and the stock solution supply plates 1 are suspended from both furnace cloths 5 and 5, respectively. On the other hand, for the connecting rods 3, 3 located below, cloths 7. ...-, 7f
t Sewn string-like member 8. .

A pair of furnace cloths 5, 5 with the stock solution supply plate 1 suspended between them.
is interposed between the door panels 9.9 as shown in FIG.

The furnace plate 9 has a stock solution hole 12 formed above the outside of the filtration surface 11 by a packing member 18 such as a comb, and a stock solution supply plate fitting portion 11!11 lO formed below the stock solution hole 12. There are seven. Therefore, when the door plate 9 is tightened, the stock solution supply il fits into the recess 10 yen together with the furnace cloth 5, and the stock solution hole 12 is filled with a large diameter IIl'! Seal the lower half of J.

Now, opening and tightening of the furnace plate 9 are performed as follows.

From the open state of the furnace plate 9 shown in FIG. 4(a) to FIG. 4(b)
As shown in FIG. 9, when the furnace plate 9 is tightened, the packing member 18 that forms the liquid solution hole 12 of one furnace plate 9 closes the liquid solution hole 12 of the other furnace plate 9 in the large upper half of the liquid solution hole 12. In addition to closely contacting and sealing the packing member 18 to be formed, the roughly lower half of the stock solution hole 120 connects the arc portion 4° 4 of the stock solution supply plate l suspended from the furnace cloths 5 to the opening 6 of each furnace cloth 5. Recessed portions 10. of the door panels 9, 9 along the lower circular ridges. 'IO, and the stock solution supply plate 1 and packing members 18 and 18 are brought into close contact and sealed to prevent the stock solution from entering between the furnace cloth 5 and the door plate 9. The undiluted solution in the furnace plate 9 and the undiluted solution flowing through the holes 12 pass through the opening 6 in the furnace cloth 5 to the undiluted solution supply plate l.
It flows reliably and smoothly into the p-chamber 16 between the furnace cloths 5, 5 through the gap 15 formed between the two plates.

Usually, the furnace plates 9, 9 are opened to collect offshore debris after the completion of p-period. This P residue collection is performed by injecting cleaning water from the cleaning nozzle 14 to wash the furnace cloth 5 when the furnace cloth 5 is wound onto the lower winding loaf 13 by the furnace cloth traveling device. . At this time, as shown in FIG. 5, as the furnace cloth 5 is wound up, the stock solution supply plate 1 is moved from the string-like member 8. ....

When suspended from the undiluted solution supply plate 8, it comes into contact with the undiluted solution supply plate 1 and separates from the furnace cloth 5. P residue that has entered during the process can be easily recovered.
Furthermore, as shown in FIG. 6.7, instead of the pair of furnace cloths 5, 5 having the punched openings 6.6,
Two pieces i+1 of furnace cloths 19 having 9a are put together and the opening 1 is opened.
9a, a cloth 20 of the same quality as the furnace cloth 19 is sewn in contact with the periphery of the openings 19a, 19a on both sides, and an opening 21 is provided at the lower part of the cylindrical sewing part 19b. Cloth 17 can also be used. When using this continuous furnace cloth 17, the raw material supply gate 1 is placed so that the circular arc portions 4, 4 of the raw solution supply plate l are aligned with the lower arc of the sewn portion 19b.
is suspended from the furnace cloth 5 with string-like members 8, 8. Therefore, the stock solution flows through the sewn portion 19b and passes from the opening 21 formed at the lower part of the sewn portion 19b through the gap 15 of the stock solution supply plate l to the furnace chamber 16 formed in the furnace cloth 19.19Ii11. flow inside. When the continuous furnace cloth 17 is used, the displacement of the stock solution supply plate 1 with respect to the continuous furnace cloth 17 is reduced, and the sealing performance around the stock solution hole of the furnace plate is further improved.

In this example, the stock solution supply plate was interposed between the furnace cloth and suspended from the first to the second, so that the undiluted solution supply plate was suspended between the furnace cloth and the furnace cloth. F r = No protrusions protrude from the field side. Therefore, when the furnace cloth is running, the stock solution supply plate may come into contact with the filtration surface of the door plate, causing damage to the filtration surface, or causing failure of the furnace cloth hanging device.
Alternatively, the vertical movement of the furnace cloth is not obstructed, and the furnace cloth can run smoothly. In addition, in the past, there were cases where a backing plate for fixing the stock solution supply plate was protruded between the furnace cloth and the furnace plate, but in this case, when the furnace cloth was running, the backing plate There were problems such as contact with the filtration surface of the door plate or other holes, damaging the filtration surface.

Although the structure and operation of the device according to the illustrated embodiment are as described above, the invention is not limited to this embodiment.
It can be implemented in various other ways.

For example, the shape of the plate material 2 of the stock solution supply plate 1 is not limited to an annular shape, but may be a square shape.

Also, 4 connecting rods 3. ..., string-like member 8 on all 8,
..., 8 may be wound around only the connecting rod 8.3 located above.

In this case, when the furnace cloth 5 is wound up onto the take-up loaf 1B during cleaning of the furnace plate 9, the furnace cloth 5 and the stock solution supply plate 1 are considerably opened, and the offshore sediment collection becomes easier.

Furthermore, in place of the connecting rod 3, specifically 1" 1 is shown, although not shown, it is also possible to use a double-threaded member having a right-handed thread on the - side and a left-handed thread on the other side. Connect both plates by screwing them into each plate.Then, both screws are rotated in one direction to move the plates closer to each other, and both screws are rotated in the opposite direction to separate the plates from each other. By moving the plate materials and adjusting the gap between them, the adhesion force of the door plate to the area around the solution hole may be adjusted.Also, when the above-mentioned double threaded member is used, it is possible to adjust the adhesion force of the door plate to the area around the solution hole. If fiber waste accumulates in the gap between the stock solution supply plates in a filter press that processes stock solutions, the stock solution supply plate can be easily separated and cleaned by rotating both screw members. The supply path for the stock solution to the p chamber of the supply plate is formed by the gap between the two plates.
7, so there is generally less accumulation of fiber waste.

Further, the connecting rod may be formed of a conical protrusion having end surfaces facing the opposing surfaces of the pair of plates, and the end surfaces being planes approximately parallel to the plates. Therefore, when the door plate is tightened, the opposing end faces of the protrusions come into contact with each other, thereby forming a gap between the two plate members. By doing this, the structure of the stock solution supply plate becomes simpler, and since the two plates are separated when the furnace plate is opened, there is no possibility that offshore sediment will accumulate in the gap, and cleaning will be easier.

Furthermore, the door plate is not limited to the one in which the four parts for fitting the liquid solution supply plate are formed only below the liquid solution hole in the door plate, but may also be a door plate in which a recessed part is formed around the liquid liquid hole in the upper part as well.

As described in detail in the above embodiment, the liquid supply plate of the filter press according to the present invention is composed of a pair of plates having an arcuate portion at the top and a connecting member that connects the plates, so the structure is very simple. It's simple, doesn't have door residue accumulating inside, and is easy to repair and prevent from being counterfeited. In addition, the upper part of each plate is provided with an arc part that extends over the lower arc of the opening of the furnace cloth.
Since we are careful to seal the approximate lower part around the raw solution hole in the door plate that communicates with the opening of the furnace cloth, a furnace plate of the type that supplies the raw solution from outside the filtration surface can be sufficiently sealed, and the sealed area by the raw solution supply plate is different from the conventional one. Compared to the case where the stock solution supply plate is also sandwiched above the stock solution hole to seal the entire circumference of the stock solution hole, the number is reduced, the sealing performance is improved, and the weight of the stock solution supply plate can be further reduced.

In addition, when the connecting member is made of double-threaded screws, the gap between the two plate members of the stock solution supply plate can be adjusted using the double screws, and the adhesion force of the door plate to the area around the stock solution hole can be adjusted.

Furthermore, if the connecting member is suspended from the Fi cloth using a string-like member or the like, the undiluted solution supply plate can be attached and removed from the furnace cloth very easily and reliably positioned at a predetermined position. It is also easy to clean the parts of the furnace cloth that come into contact with the furnace cloth.
