Description

[Detailed description of the invention] [Industrial application field] The invention is installed on the plate of a filter press,
The present invention relates to a stopper for a plate that provides robustness to the plate.

[Conventional technology]

The undiluted solution discharged from the sedimentation basin, filter basin, etc. and concentrated in the concentration tank is compressed in a filter press.
It is overtreated and discharged as a solid (cake).

A filter press has a structure in which two sheets of cloth are placed between multiple plates to form a chamber, and the undiluted solution in each chamber is supplied, filtered by hydraulic pressure, and drained. Each plate is opened and the solid content formed between the two pieces of cloth is allowed to fall due to its own weight,
It is discharged to the outside.

During the above-mentioned pressing and passing, the solid content is not uniformly formed in the final stage of cake formation.
There is a difference in the pressure acting on each side of the plate forming the boundary wall of adjacent chambers, and the plate may break due to the gradually increasing differential pressure.

Conventionally, a stopper was fixed to the surface of the board to maintain the chamber spacing to prevent the board from deforming.
Efforts have been made to prevent the board from breaking.

[The problem that the idea attempts to solve]

Conventionally, the method for fixing stoppers to a board involves fixing many stoppers to both sides of a single board by gluing, welding, or screwing to a board that has an overactive surface. The impact and man-hours required could not be ignored.
Furthermore, if the plates are slightly deformed, the stoppers located at symmetrical positions on adjacent plates no longer come into proper contact with each other, and as a result, it is sometimes difficult to attach the stoppers.

The object of the present invention is to eliminate the above-mentioned drawbacks and provide an economical stopper for a plate.

[Means to solve the problem]

In order to achieve this objective, the present invention provides a filter press for filtering and squeezing stock solution, which has through holes 8 in the plate 3 and mounting holes 9 in the peripheral edge plates 4 provided on both sides of the plate 3. The stopper is installed on the plate body 1 and consists of a pair of clamping members 11 each having a clamping step 10 symmetrically formed on the peripheral edge of the flat inner surface of a synthetic resin plate.
A connecting hole 13 having a hooking step 12 on the inner peripheral surface is formed in the center of the holding member 11b, and a connecting hole 13 is formed in the center of the inner surface of the other holding member 11b through the through hole 8 and inserted into the connecting hole 13. , a latching peripheral surface 14 that can be latched to the latching step portion 12
It is characterized by integrally protruding a connecting rod 15 provided on the outer periphery.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a plate main body, and this main body 1 consists of a plate 3 having an outer circumferential frame 2, over-action plates 4 made of mesh sheets fixed to both sides, a plate handle 5, a stock solution supply port 6, etc. be done.

A plurality of stoppers 7 are installed on such a plate body 1. For this purpose, a through hole 8 is formed in the plate 3 at the installation position of the stopper 7, and a mounting hole 9 that is concentric with the through hole 8 and has a larger diameter than the through hole 8 is formed in the overaction plate 4 on both sides of the plate 3. is formed.

As shown in FIG. 2, the stopper 7 uses a pair of clamping members 11 having clamping steps 10 symmetrically formed on the peripheral edge of the flat inner surface of a circular or square plate made of synthetic resin. Then, one holding member 11
A connecting hole 13 having a hooking step 12 on the inner circumferential surface is formed in the center of a, and a connecting hole 13 is formed in the center of the inner surface of the other holding member 11b through the through hole 8 of the plate 3. A connecting rod 15 is provided integrally with a connecting rod 15 that is fitted into the inside and has a locking circumferential surface 14 on its outer periphery that is hooked on the locking stepped portion 12. This connecting rod 15 has a function of contracting and expanding in the circumferential direction by a groove 16 formed inward from the tip. In addition, both the holding members 11a,
The peripheral corners of the flat outer surface of the plate 11b are formed into a slope shape so that the plate can easily run without getting caught. Furthermore, the holding step portion 10 has an outer diameter that is the same as or slightly smaller than that of the mounting hole 9.

Next, the manner in which the stopper 7 is attached to the plate 3 will be explained with reference to FIG.

One of the attachment methods is to arrange the clamping members 11a and 11b on both sides of the plate 3, and position the connecting hole 13 of the clamping member 11a concentrically with the through hole 8. In this state, by pushing the connecting rod 15 of the clamping member 11b through the through hole 8 and further into the connecting hole 13 of the clamping member 11a, the peripheral surface of the connecting rod 15 contracts and enters the connecting hole 13. The latching peripheral surface 14 is the latching stepped portion 12
When passing through, the connecting rod 15 expands in the circumferential direction, the latching circumferential surface 14 comes into contact with the latching step 12, and the connecting rod 15 does not come out of the connecting hole 13. Another method of attachment is to attach the clamping member 1 on one side of the plate 3.
The connecting rod 15 of 1b is made to protrude to the other surface through the through hole 8 and is held down, and the connecting hole 13 of the clamping member 11a is fitted into the connecting rod 15, and the locking stepped portion 12 and the locking peripheral surface 14 are inserted.
All you have to do is touch them and hook them.

As described above, the pair of clamping members 11 are attached to the plate 3.
, the flat inner surface of each clamping member 11a, 11b will be in close contact with the plate 3, and the mounting hole 9 of the overaction plate 4 will be located within the clamping step 10.

Then, the outer surfaces on both sides of each stopper 7 and the plate outer peripheral frame 2 are at the same height position.

[Effect of idea]

According to the present invention described above, a pair of clamping members 1 each having a clamping step 10 symmetrically formed on the peripheral edge of the inner surface.
One of the clamping members 11a of 1 is formed with a connecting hole 13 having a hooking step 12, and the other clamping member 11
b has a protruding connecting rod 15 having a locking circumferential surface 14 that can contact and lock the locking stepped portion 12, so clamping members 11a and 11b are installed on both sides of the through hole 8, Both clamping members 11a and 11b are integrally connected by simply fitting the connecting hole 13 and the connecting rod 15 together. Moreover, the flat inner surface of each clamping member 11a, 11b and the plate 3 are in close contact with each other, and both the mounting holes 9 of the overaction plate 4 are clamped within the clamping step part 10, so that the plate 3 and the overaction plate and stopper 7
The fixed state becomes stable.

Moreover, since the outer surfaces of each stopper 7 and the outer circumferential frame 2 of the plate are at the same height, the outer circumferential frame 2 of the adjacent plate main body 1 comes into close contact with each other, so that the stoppers 7 also come into close contact with each other, and the outer surface of the stopper 7 The deformation force from the plate transmitted through the plate is absorbed by each stopper 7 and smoothly transmitted to the plate 3. Similarly, the differential pressure generated on each plate 3 is reinforced by the stopper 7, causing the plate 3 to deform and break. There's nothing to do.

In particular, the holding members 11a and 11b are firmly connected only by fitting the connecting hole 13 and the connecting rod 15,
Since it is easy to attach and remove, and the clamping member 11 has a form that allows mass production, production,
There are significant economic advantages in installation.
