Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a filter press consisting of a plate of an outside-of-plane stock solution supply type with stock solution holes provided in the upper part of the frame, and more specifically, the present invention relates to a filter press that is made of a plate for supplying stock solution outside the surface and having stock solution holes in the upper part of the frame. This invention relates to the structure of a stock solution supply device supported from a cloth hanging rod that guides the stock solution from the stock solution hole between a pair of cloths.

Prior Art Conventionally, a filter press has been constructed by providing a stock solution hole on the upper surface of each plate, sandwiching a pair of cloths between the plates, and further suspending a stock solution supply plate from the cloth between the two cloths. (For example, Tokuko Sho 52-
Publication No. 2742). This stock solution supply plate has a through hole that communicates with the stock solution supply port of the cloth in a single plate, and
A liquid supply path extending downward from the through hole and having an open lower end is provided inside. Then, the adjacent plates are tightened to tightly sandwich the stock solution supply plate between the upper surfaces of the plates, and the stock solution is passed through the stock solution hole in the plate and the stock solution supply port in the cloth from the through hole of the stock solution supply plate to the liquid supply path. The liquid is passed through the cloth and supplied to a chamber formed between the cloths.

By the way, since the tightening pressure of the plate is mainly applied to the frame surrounding the upper surface, the upper surface of the cloth is bent along the concave part of the upper surface of the plate.
After removing the residue, even if you try to return the stock solution supply plate attached to the bent cloth to its original position, the stock solution supply plate swings unstably. There was a problem with poor adhesion.

In addition, in particular, since the upper surface of the compressible plate is made of an elastic material, there has been a problem in that the adhesion is significantly deteriorated.

Furthermore, since the stock solution supply plate is suspended from the cloth, the expansion and contraction of the cloth causes the phase between the stock solution supply port of the cloth and the through hole of the stock solution supply plate to shift, making it impossible to supply the stock solution smoothly. It was hot.

Purpose of the Invention It is an object of the present invention to solve the above-mentioned problem, and the purpose of the present invention is to tightly clamp the stock solution introduction plate at the upper part of the frame of the plate and suspend it from a cloth hanging rod separately from the cloth. As a result, even in large filter presses or squeeze type plates, the stock solution introduction plate can be firmly held in close contact with the plate, and the position can be adjusted to follow the expansion and contraction of the cloth, allowing the stock solution to be supplied smoothly. An object of the present invention is to provide a stock solution supply device for a filter press.

Structure of the Invention The structure of the present invention is such that a cloth hanging rod is positioned above the adjacent plates, a pair of cloths are suspended between the plates from the cloth hanging rod, and a stock solution introduction plate is positioned between the cloths. The area around the opening of the stock solution hole that penetrates through the upper part of the frame of the plate is covered with a packing member, and a recess is formed in the packing member, so that when the plate is tightened,
In a filter press in which the stock solution introduction plate is closely fitted into the recess through a cloth, a support rod is suspended from the cloth hanging rod via an attachment member, and the stock solution introduction plate is attached to the support rod. The support rod is characterized in that it is supported so as to be swingable and movable in the axial direction of the support rod. The above-mentioned mounting member is composed of, for example, a bracket or a threaded rod and a nut.

Embodiments The present invention will be specifically described below based on illustrated embodiments.

As shown in FIGS. 1, 2, and 3, a filter press equipped with a stock solution supplying device according to an embodiment of the present invention has a structure in which when a pressing plate 2 and a normal plate 2' are opened, adjacent pressing plates 2 While running a pair of cloths 4, 4 whose upper ends are supported by a cloth hanging rod 3 forming a part of a cloth hanging device between ordinary plates 2', vertically,
At the same time, with the plates 2 and 2' tightened together, the stock solution introduction plate 1 is inserted from the stock solution holes 2a and 2'a of the plates 2 and 2'.
The stock solution is introduced between a pair of cloths 4, 4 through the cloth.

In the upper portions 2b and 2'b of the frame portions of the plates 2 and 2', stock solution holes 2a and 2'a are respectively provided in the thickness direction, and recesses are provided around the stock solution holes 2a and 2'a. The recess is filled with a packing, and the stock solution holes 2a, 2'a are covered with a packing member 9. This packing member 9 has the above-mentioned stock solution hole 2a,
Concave portions 10, 10 are provided on the surface facing each opening portion of 2'a, continuing in the vertical direction and reaching from the outside of the frame to the upper surfaces 2c, 2'c.

The stock solution introduction plate 1 is in close contact with this recess 10.
I'm trying to make sure they fit together.

The stock solution introduction plate 1 is a plate material whose upper half is semicircular and whose lower half is rectangular, and has a through hole 1a penetrating in the thickness direction of the plate material in the center, and a through hole 1a extending downward from the through hole 1a. Liquid supply passages 1b, 1b are provided through the liquid supply passages 1b, 1b to allow the stock solution to pass from the through-hole 1a to the liquid supply passages 1b, 1b. A protrusion 1c is formed at the upper end of this stock solution introduction plate 1, and a square-shaped bracket 5 is fixed to the protrusion 1c with bolts 6, 6, and is attached to the cloth hanging rod 3 via brackets 8, 8 as attachment members. The above-mentioned bracket 5 is attached to the supported support rod 7 so as to be swingable and can be pushed left and right, and the stock solution introduction plate 1 is suspended therefrom. In addition, the lower surface of the stock solution introduction plate 1 is cut off diagonally, and the liquid supply path 1 is
While increasing the area of the lower end opening of b, 1b,
The cleaning liquid is made easy to enter into the liquid supply paths 1b, 1b from the lower end opening, and the wall surface of the pressing plate 2 is prevented from being damaged due to the swelling of the pressing plate 2.

The stock solution supply device configured in this way operates as follows.

When adjacent plates 2, 2' are tightened together as shown by the two plates 2, 2' on the right side in Fig. 2 and the two plates 2, 2' on the upper side in Fig. 3, the above The stock solution introduction plate 1 is tightly fitted into the recesses 10, 10 formed in the packing members 9 of the opposing frame upper portions 2b, 2'b of the plates 2, 2' via the cloths 4, 4. After that, the stock solution is transferred to the stock solution hole 2 of the plate 2, for example.
a. Let the stock solution flow into the stock solution supply port 4a of the cloth 4 and the through hole 1a of the stock solution introduction plate 1, and let some stock solution flow through the liquid supply path 1b, 1b from the through port 1a of the stock solution introduction plate 1,
It is supplied into a chamber 11 formed between a pair of cloths 4, 4, and filtration is performed. The remaining stock solution flows from the through hole 1a of the stock solution introduction plate 1 through the stock solution supply port 4a of the cloth 4 into the stock solution hole 2'a of the plate 2' adjacent to the plate 2.

On the other hand, when the plates 2, 2' are opened as shown by the two plates 2, 2' on the left side in Fig. 2 and the two plates 2, 2' on the lower side in Fig. 3, the stock solution is introduced. The plate 1 is connected to the concave portions 10 and 1 of the packing member 9 of each plate 2 and 2'.
0 and lower the cloth hanging rod 3 downward, for example, as shown in FIG. 4, the cloth 4,
The cleaning work is performed while winding up the cloth with the cloth winding roller 12. At this time, the pair of cloths 4, 4 are connected to the plate 2,
2', for example separate winding rollers 12,
12 in different directions, the pair of cloths 4, 4 are wound as shown in FIG.
The distance between the undiluted solution introduction plate 1 and each cloth 4 is increased, so that the contact portion between the undiluted solution introduction plate 1 and each cloth 4, the through-hole 1a of the undiluted solution introduction plate 1, and the liquid supply path 1
b and 1b can also be washed. In addition, in FIG. 4, the cloth winding roller 12 of each plate shows the stock solution introduction plates 1, 1 in a state in which the winding force thereof is released, and the stock solution introduction plate 1 protrudes below from the space between the plates 2, 2'. This makes it easier to handle not only cleaning, but also assembly, repair, and conversion. When the winding force is applied to the cloth winding roller 12, the cloths 4, 4 are stretched between the winding rollers 12, 12 of the adjacent plates 2, 2' as shown by the dotted line in the figure. The stock solution introduction plate 1 is lowered to the position shown by the dotted line in the figure.

According to this embodiment, when the cloth 4 expands and contracts and the positions of the stock solution supply port 4a of the cloth 4 and the through hole 1a of the stock solution introduction plate 1 are misaligned, the cloth hanging rod 3 is moved slightly horizontally toward the board side when the board is tightened. By moving the hanging screw at the end of the cloth hanging rod 3 up and down,
The positions of the cloth 4 and the stock solution introduction plate 1 can be adjusted. Further, the position can be adjusted in the same way by pushing the bracket 5 of the stock solution introduction plate 1 left and right or by replacing it with another bracket. Furthermore, since the lower end of the stock solution introduction plate 1 is cut off diagonally, the opening area of each liquid supply path 1b is increased, and when the plate is tightened, the stock solution can be more smoothly supplied into the chamber 11, and the During cleaning, the cleaning liquid enters the liquid supply path 1b from the opening of each liquid supply path 1b,
The liquid supply path 1b can be cleaned.

Note that the present invention is not limited to this example, and can be implemented in various other ways. for example,
A fifth,
A threaded rod 13 as shown in FIGS. 6 and 7 may also be used. This threaded rod 13 has a threaded portion 13a passed through the cloth hanging rod 3 and is fixed with nuts 14, 14, thereby forming a mounting member. A support portion 13b is provided at the lower part of the threaded rod 13, and the support portion 13b
A support rod through hole 13c and a locking hole 13d having a smaller diameter than the through hole 13c are connected to each other. and,
The small diameter portions 7a provided at each end of the support rod 7 are locked in the locking holes 13d of the support portion 13b in the through holes 13c of the support portion 13b, and the lock holding pins 15 are attached to the through hole surfaces. Attach the small diameter part 7a of the support rod 7
is held in place so that it does not come off from the locking hole 13c of the support portion 13b. In this way, by adjusting the screwing position of the nut 14 on the threaded portion 13a of the threaded rod 13 and moving the position of the support rod 7 with respect to the cloth hanging rod 3 up and down, the stock solution introduction plate 1 with respect to the cloth 4 can be adjusted. The position can be easily adjusted. Further, as shown in FIG. 8, rubber slip prevention members 16, 16 are movably fitted to the support rods 7 on both sides of the square-shaped bracket 5 at the upper end of the stock solution introduction plate. Slip in the axial direction may be prevented. It is also possible to carry out a filter press in which all the plates are press-type plates 2 or only ordinary plates 2'. Further, the shape of the stock solution introduction plate 1 is not limited to that of this embodiment, and may be any shape such as a circle. Furthermore, if the undiluted solution introduction plate 1 is removed from the support rod 7 and replaced, and its through hole 1a is made smaller than the undiluted solution supply port 4a of the cloth 4, the area around the undiluted solution supply port 4a of the cloth 4 can be protected, and the undiluted solution can be Flow rate adjustment can be performed.
Furthermore, as the through-hole 1a of the stock solution introduction plate 1 goes from the stock solution supply side of the filter press toward its end side,
It may be made gradually smaller to provide a constriction gradient to the stock solution supply path.

Effects of the Invention In the present invention, the stock solution introduction plate is attached to the support rod supported by the cloth hanging rod separately from the cloth, so even if the cloth is bent due to tightening of the plate, only the stock solution introduction plate can be moved in the axial direction of the support rod. By moving the stock solution introduction plate, the stock solution introduction plate can be closely fitted into the recess of the packing member on the upper part of the frame portion of the plate, and the position of the stock solution introduction plate can be easily and reliably adjusted. In addition, since the cloth and the stock solution introduction plate were supported separately on the cloth hanging rod,
When washing cloth, if the cloth hanging rod is lowered to the bottom of the plate and the cloth is wound up on the cloth winding device, the cloth and the stock solution introduction plate are separated and the area between the cloth and the stock solution introduction plate can also be thoroughly cleaned. can. In addition, since the undiluted solution introduction plate is supported by a support rod instead of being supported by cloth, the undiluted solution introduction plate does not come into contact with the upper surface of the plate as the cloth runs. Damage to the fabric can be prevented. In addition, since the undiluted solution introduction plate is tightly fitted into the recess of the packing member provided on the upper part of the frame of the plate, the undiluted solution introduction plate can be directly held between the packing member by the tightening force of the plate frame. Adhesion between the stock solution introduction plate and the packing member can be improved, and the stock solution introduction plate can be easily and reliably positioned with respect to the stock solution holes in the plate and the stock solution supply port on the cloth.

Further, if the stock solution introduction plate is made detachable from the cloth hanging rod, the adhesion to the packing member can be easily adjusted by replacing the stock solution introduction plate with a different stock solution introduction plate having a different shape, size, etc. Conversely, by changing the packing member that forms the concave portion of the plate, the adhesion to the stock solution introduction plate can be easily adjusted.
