Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a frame type filter press, and more specifically, a cloth is suspended and supported on both sides of the frame,
A stock solution is introduced into the chamber formed between the frames through a stock solution hole provided in the center of the fabric, and the filtered solution is taken out through a hole drilled in the frame, and the residue is discharged by opening the frame.

Prior Art The frames used in this type of filter press are generally quite heavy and inconvenient to handle, and require a relatively large driving force to move the frame, resulting in high costs. There's a problem. Also,
It is necessary to have a means to maintain the distance between the cloths and to vibrate the cloths to prevent them from sticking together, but if this means is provided integrally with the frame by laminating wire mesh, the shape of the frame will change. It gets complicated. Furthermore, it is generally necessary to also assemble a stock solution supply plate to the stock solution hole in the fabric, making assembly difficult.

Purpose of the Invention The present invention has been made in view of the above-mentioned problems, and it aims to reduce the weight by simplifying the shape of the frame, maintain the distance between the cloths, and simplify the shape of the members that are likely to generate vibrations. It is intended to be easily assembled, to reliably prevent the fabrics from sticking together, and to prevent excessive deterioration in performance due to the member.

Structure of the invention In order to achieve the above-mentioned object, the present invention has the following features:
The frame has a simple "R"-shaped shape to reduce weight, and a cloth-to-fabric spacing-maintaining and cloth-vibrating member is installed separately from the frame to maintain the distance between the cloths and vibrate the cloth. The member can be assembled very easily by fitting it into the hole connecting portion, and the shape of the member is designed so that excessive performance is not restricted. Specifically, a roughly square-shaped frame, a cloth suspended across the frame and having a solution hole in the center, and a center fitting part set to a size almost corresponding to the solution hole to maintain the distance between the cloths. The solution hole of the cloth suspended on both sides of the frame is sewn and connected in advance, and the cloth spacing holding and cloth vibration member is externally fitted to the solution hole connection part. Hold the cloth spacing and cloth vibrating member between the cloths, suspend the cloth on both sides from both sides of the frame via suspension springs, and move the frame that hangs the cloth on both sides. If possible, install them in parallel,
A chamber is formed by bringing the frames into contact and closing the entire circumference of the opposing cloth between the frames, and supplying the concentrate to the chamber through the concentrate hole, and discharging the residue by moving and opening the frame. The present invention provides a frame type filter press characterized by the following structure.

Embodiments Hereinafter, the present invention will be explained in detail with reference to embodiments shown in the drawings.

In the figure, 1 is a roughly square-shaped frame, 2A, 2B
is a sheet of cloth hung on both sides of each frame 1, 3
1 is a cloth vibration member which is fitted between cloths 2A and 2B suspended with frame 1 in between to maintain the distance between the cloths and to vibrate the cloth.

The rectangle-shaped frame 1 is integrally formed with protruding ears 4A, 4B, 4C, and 4D at four corners, and has a pair of handle members 5A, 5B protruding from both sides. At the tips of the handle members 5A, 5B, the lower ends of rods 6A, 6B for supporting cloth are fixed and erected, and spring support parts 7A, 7B are provided at the upper ends of these rods 6A, 6B. The spring support parts 7A, 7
The upper ends of the suspension springs 8A, 8B are locked to B, and a pair of left and right fitting holes 9 are provided at the lower ends of each suspension spring 8A, 8B.
Hanging tools 10A and 10B provided with A and 9B are connected. Between the hanging tools 10A and 10B are bars 11A and 11B to which the upper ends of the cloths 2A and 2B are fixed.
, with both ends inserted into the fitting holes 9A and 9B and mounted on the shaft, and one cloth 2A is attached to one adjacent frame 1.
The other cloth 2B is suspended and supported on the right side of the other frame 1 (FIGS. 1 and 2). Then,
Cloths 2A and 2B suspended across frame 1 are attached to adjacent hanging tools 10A and 2B via bars 11A and 11B.
10B, 10A, and 10B are respectively hung separately.

The cloth 2 is large enough to cover the entire side of the frame 1,
A stock solution hole 13 is bored in the center position. The stock solution hole 13 is located approximately at the center of the hollow portion 12 surrounded by the frame 1. The cloths 2A and 2B suspended with the frame 1 in between are connected by sewing the periphery of the liquid solution hole 13, and the above-mentioned cloth spacing holding and cloth vibrating member 3 is fitted and attached to the liquid solution hole connecting part. (Figure 2).

As shown in FIG. 3, for example, the cloth spacing holding and cloth vibrating member 3 includes an inner annular portion 15, an outer annular portion 16, and a connecting portion 17 that connects both annular portions at a 90 degree interval. These are integrally formed from a thin plate, and ribs for liquid passage are attached to the surface. The inner ring part 15 has an inner periphery set to a size almost corresponding to the stock solution hole 13, and is fitted onto the stock solution hole connection part of the cloth, and one of the cloths is rolled up to form the inner ring. By passing it through the section 15, it is fitted between the cloths 2A and 2B, and by suspending both the cloths 2A and 2B as described above, the cloth that also serves to maintain the distance between the cloths is placed approximately in the center of the hollow section 12 of the frame 1. The vibrating member 3 is supported. By supporting in this way, a space S ₁ is created in the frame 1 between the inner surface of the frame 1 and the outer peripheral surface of the outer annular portion 16.
However, there is a gap _S2 between the outer annular part 16 and the inner annular part 15, and these gaps serve as liquid outflow areas, and the cloth spacing and cloth vibration member 3 prevents excessive performance from being restricted. That's what I do.

As shown in FIG. 1, the frame 1, the cloths 2A, 2B, and the cloth vibrating member 3 are arranged such that the frame 1 is movably arranged in parallel between a fixed plate 20 and a movable plate 21. A pair of cloths 2B and 2A, in which the cloth-to-cloth spacing holding and cloth vibration member 3 is fitted into the connecting part of the solution hole, are attached to the hangers 10A and 10B, 10A and 10 on both sides via bars 11A and 11B so as to sandwich the frame 1 therebetween.
It is suspended from B. When the movable plate 21 is moved to the fixed plate 20 side and the frames 1 are brought into contact with each other to form a continuous state, the entire circumference frame 1 of the cloths 2B and 2A suspended from the opposing surfaces of the adjacent frames 1, 1 and are tightly closed to form a chamber 25. Each chamber 25 communicates through a stock solution hole 13, and the stock solution hole 13 at the upstream end communicates with a stock solution press-in tube 19 provided through the fixed plate 20.

The liquid flowing out from the chamber 25 through the cloths 2A and 2B into the gap of the frame 1 is passed through the liquid extraction hole 26 opened at the lower corner of the inner peripheral surface of the frame 1 to the lower ear portion 4.
It is taken out through through holes 27 drilled at C and 4D.

By having the above configuration, in the event of an
When a stock solution supply pump (not shown) is connected to the stock solution injection pipe 19 to pump the stock solution, each chamber 25 is filled with the stock solution at high pressure through the stock solution hole 13. For this reason, the left and right cloths 2A and 2B sandwiching the frame 1 come close to each other, but the distance between them is maintained by the cloth-to-cloth spacing holding and cloth vibration member 3 located at the center. Then,
The liquid passes through the cloths 2A and 2B from the chamber 25,
The liquid flows out into the spaces S ₁ and S ₂ in the frame 1 and is taken out through the liquid extraction hole 26 .

After this, the frames 1 are moved to widen the space between adjacent frames 1 to open the frame, and the residue is discharged from the open lower end of the chamber 25. In addition, since the cloths 2A and 2B are supported by the suspension springs 8A and 8B, they easily vibrate, and the cloth spacing holding and cloth vibration member 3 held by the vibrating cloths 2A and 2B vibrates, causing the cloth 2A to vibrate. , 2B from clogging with residue.

The present invention is not limited to the above-mentioned embodiments, but can be suitably implemented even when a compression diaphragm is provided. That is, as shown in the overlapping arrangement of frames shown in FIGS. 4 and 5, a compressed diaphragm 30 made of an elastic material such as rubber and having many irregularities on its surface is stacked on the inside of the cloths 2A and 2B that sandwich the frame 1. Combined,
The cloth spacing holding/cloth vibrating member 3 is supported at the stock solution hole 30a of the pressing diaphragm 30, and the upper and lower edges of the pressing diaphragm are connected to the bolts 3.
By fixing the parts 1 and 32 to each other, installation is extremely simple. Ear portion 4B of the frame shown in Fig. 4
The compressed fluid is forced into the space between the opposing compressing diaphragms through the through hole 28 and the communicating hole 29 passing through the diaphragm. In this case, the opposing compression diaphragms 30
The distance between the cloths is maintained by the cloth-to-cloth vibrating member 3, which reliably prevents polymerization and facilitates the supply of compressed fluid. to help the cloth vibrate. Reference numerals 26' and 26' indicate liquid drain holes formed in the diaphragm and the frame, which communicate from the diaphragm surface to the through hole 27 in the frame. Also, in Figure 4, frame 1
A through hole 38 is also provided in the upper ears 4A, 4B, and the through hole 38 is communicated with a tunnel hole 39 opened in the upper corner of the inner peripheral surface of the frame 1 and the diaphragm.
8. Through the tunnel hole 39, the cleaning liquid is sprayed onto the surface of the diaphragm and the back surfaces of the cloths 2A and 2B.

Further, as shown in FIG. 6, a large number of protrusions 40 are provided on the surface of the fabric spacing maintaining and fabric vibrating member 3, and the protrusions 40 form liquid grooves 41 for guiding the flow of liquid. By making the protrusions 40 act as a cloth for reinforcement, and by bringing the protrusions 40 into contact with the cloth during vibration, the effects of vibration application can be further enhanced. In addition, FIG. 6 shows a case in which the outer plate is connected to the outer periphery of a horseshoe-shaped support plate with an elastic pin material, and the outer plate is formed into a strip. Each cloth is vibrated by being dusted from the back side. Furthermore, in the example shown in FIG. 5, FIG. 7 shows a structure in which a cloth spacing holding and cloth vibrating member 3 is sandwiched between the cloth and the diaphragm so that the member 3 acts directly on the cloth.

Effects of the Invention As is clear from the above explanation, according to the frame type filter press according to the present invention, since the frame has a simple, roughly square shape, it is possible to reduce the weight and to manufacture it at low cost. Also,
Since the distance between the cloths is maintained by the cloth distance maintaining and cloth vibrating member, it is possible to reliably prevent the cloth from clumping together.Furthermore, the cloth distance maintaining and cloth vibrating member can be easily vibrated. can prevent the cloth from clogging by applying vibration to the cloth. In addition, the cloth spacing holding and cloth vibrating member can be easily attached to the connecting portion of the raw solution hole of the cloth regardless of the frame, making assembly extremely simple and reducing the number of parts. Furthermore, the cloth spacing holding and cloth vibration member does not restrict excessive performance of the cloth, and has various advantages such as improved overperformance compared to the case where a conventional spacing maintaining member is provided. .
