Detailed Description of the Invention [Industrial applications]

The present invention relates to a pressurizing fluid supply control device in a plate type press having a forced pressing step.

[Prior art]

In the conventional plate type machine having the forced overstep after the primary overstep, as shown in FIG. 14, the diaphragm D disposed by distributing and supplying the fluid into the fluid supply plate A is arranged in each of the overpass chambers. The remaining liquid in the excess chamber was dehydrated by expanding and displacing the flexible body such as.

However, the progress speed of excess in each excess chamber is often different depending on the clogging state of the cloth, and in this case, the excess progress is delayed in the adjacent excess chambers of the fluid. There is a situation in which one of the excess chambers is press-fitted, and over-progression is advanced or ended, but the other excess chamber is not press-fitted. That is, the slag is solidified and becomes immobile when the excess is near the end. As a result, as shown in FIG. 14, the excessive chamber on the side into which the fluid is press-fitted presses the other side to deform and damage the plate, which may be extremely dangerous. Therefore, the present invention provides a control device capable of press-fitting a fluid into each of the excess chambers to perform a proper forced excess even when the progress of the excess in each of the excess chambers is different, and also capable of preventing the plate from being deformed and damaged. Is.

[Means for Solving the Problems]

For this reason, the present invention provides a fluid supply pipe connected to a fluid supply device and a fluid supply pipe connected to a fluid supply device with a stock solution in a state of being aligned in a pressure-aligned manner, and a fluid supply plate connected to the fluid supply pipe. In a plate type machine equipped with a distribution pipe such as a hose that can be pressure-fed to a flexible body arranged in the excess chamber and forcing the flexible body such as a rubber film arranged in the excess chamber by expanding the fluid in the fluid supply pipe. The fitting inner cylinder is fitted and stored,
Mutually overlapping discharge holes are provided through the fluid supply pipe and the fitting inner cylinder, and the discharge holes of the fluid supply pipe are connected to the respective distribution pipes to rotate the fluid supply pipe or the fitting inner cylinder. The displacement area is provided to change the overlapping area of the emission holes. It should be noted that it is also possible to form a fitting inner cylinder by sequentially inserting and connecting the short cylinders, each of which has a discharge hole formed therein and has engaging portions that can be connected to each other at both ends, into the fluid supply pipe.

[Work]

In the present invention, the overlapping area of the transparent discharge hole is varied by relatively rotating the fluid supply pipe or the fitting inner cylinder fitted and housed in the inner periphery thereof by the displacement means for rotating either or both of them. That is, a small amount of high pressure primary injection is performed with the polymerization area reduced, and then a large amount of secondary injection is performed with the polymerization area increased. That is, first, the flexible body was separated from the pressure-bonded plate by first press-fitting a small amount at a high pressure from the discharge hole having a small polymerization area, and the pressures in the respective excess chambers were made substantially even, and then the polymerization area was increased. By injecting a large amount of the fluid from the discharge hole at a pressure lower than that of the primary injection, the fluid is supplied between the separated flexible body and the plate, and the expansion of the flexible body in each of the over chambers is prevented. There is an effect that can be made almost uniform. It should be noted that if short tubular bodies each having a discharge hole provided therein are successively inserted into the fluid supply pipe, they can be connected in series by the engaging portions formed at both ends, and if the short tubular body at one end is rotated, all the short tubular bodies are rotated. The cylinder rotates in conjunction with it.

【Example】

Hereinafter, details of the present invention will be described with reference to illustrated embodiments. The plate type machine shown in FIG. 1 is composed of a plurality of plates arranged in order and a fluid supply plate A in which a fluid passage is formed in every other plate, and both surfaces of the fluid supply plate are formed as shown in FIG. Has a conventional structure in which the diaphragm D is attached except for the stock solution supply hole. Further, as shown in FIGS. 2 to 4, as many discharge holes 1a as the number of the fluid supply plates A are provided in the fluid supply pipe 1, and each hose 3 is connected to each fluid through each valve 2. It is connected to the supply opening of the supply plate A. Then, the short cylinders 4 as shown in FIGS. 5 and 6 are inserted into the fluid supply pipe 1, and each of the short cylinders 4 has a triangular discharge hole 4a and one side end. And an engaging recess 4c that engages with the protrusion 4b is formed at the other end. The length of the short tubular body 4 is the length between the discharge holes 1a of the fluid supply pipe 1, and the short tubular body 4 is sequentially inserted and fitted into the fluid supply pipe 1 so as to be adjacent to the engaging projection 4b. The engagement recesses 4c of the short tubular body 4 are connected to form a series of fitting inner cylinders K. In this state, the discharge hole 1a of the fluid supply pipe 1 and the discharge hole 4a of the short tubular body 4 are located on the same circumference so that they can overlap each other. Further, the short tubular body 4 at the end is elastically fitted and pressed by a spring 6 by a stopper 5 sealed by a seal ring 5a. The shaft 5b of the stopper 5 has a link rod 6 of a link mechanism (not shown).
Are connected. A supply valve 7 is open-connected to the short tubular body 4 at the tip. Next, the operation of this example will be described. The stock solution is supplied in a state where the parallel plates are pressure-aligned, the solution is first passed through as in the conventional case, and then the plate is forcibly squeezed. At the time of this squeezing, the link rod 6 is rotated to rotate the shaft 5b and the stopper 5a so that the connected short cylinders 4 are rotationally displaced in conjunction with each other (see FIG. 7), and the respective discharges are released. Hole 4
A is partially polymerized in each triangular discharge hole 1a of the fluid supply pipe 1 as shown in FIG. In this state, since the overlapping area of the discharge holes 1a and 4a is small, by press-fitting the fluid from the fluid supply device into the supply pipe 1,
A small amount of fluid at high pressure is supplied to the fluid supply liquid A from each hose 3. As a result, the diaphragm D in the excess chamber is separated from the pressure-bonded plate A. Further, after the pressures of the respective excess chambers are made substantially equal by the supply of the fluid, the link rod 6 is rotated and the short cylindrical body 4 is interlockedly rotated, and as shown by the phantom line in FIG. By increasing the polymerization area of 4a, a large amount of fluid is press-fitted into the plate A at a pressure lower than that of the primary press-fitting. As a result, the fluid is supplied between the separated diaphragm D and the plate A, and the expansion of the diaphragm D in the respective over-chambers is made substantially uniform, so that the plate is pressed from one side and deformed and damaged as in the conventional case. There is no. Note that it is effective to perform this squeezing before the end of the squeeze as in the conventional method, but even if the slag is solidifying to some extent, the high-pressure small-volume supply of the fluid can expand the diaphragm of the excess chamber. It is possible to prevent damage to the plate. Therefore, it is possible to have a margin at the start time of the squeezing process as compared with the conventional case. Although this example is configured as described above, the present invention is not limited to this. For example, the shape of the discharge hole provided through the fluid supply pipe and the fitting inner cylinder does not matter. The configuration of the displacement means for rotating the fitting inner cylinder is not limited, and may be manual or electric. The other fluid supply pipe may be rotated. Also, FIGS. 9 to 1
As shown in FIG. 1, fluid passage holes are provided through all the plates, and the short cylinders 9 are rotatably fitted in the fluid passage holes. A supply hole 8 that communicates with the chamber is formed so as to open toward the excess chamber, and a fluid discharge hole 9a is provided through the short cylindrical body 9 to form a series of fluid supply paths by pressure alignment of the plates. By rotating the support rod 10 (see FIG. 12) inserted into the tubular body 9, the short tubular body 9 is interlockedly rotated, and is formed by the overlapping portion of the discharge hole 9 a and the supply hole 8. By making it possible to change the opening area of the distribution opening,
Then, secondary press-fitting may be performed with a large opening area. As shown in FIG. 13, one fitting inner cylinder 1
The configuration in which 1 is fitted to the fluid supply pipe 12 may be adopted. Further, in the case where the fitting inner cylinder is formed by the short tubular body, the shape of the short tubular body and the configuration of the engaging portions at both ends may be appropriate and may be connected to each other.

【The invention's effect】

In the present invention, by variably adjusting the polymerization area of the release holes,
Since the secondary fluid can be press-fitted between the flexible body and the plate that have been separated by the high-pressure small amount of primary fluid press-fitting, the flexible body can be expanded smoothly, so that the plate can be prevented from being deformed and damaged and safety is improved. The effect that can be ensured is great, the structure is simple, and reliable fluid supply can be performed. According to the second aspect, there is an effect that the equipment can be inexpensively installed.
