Abstract

PURPOSE:To inexpensively constitute the titled apparatus, by clamping a filter plate group by pressing filter plates in a closed state to a pressing apparatus in a plate opening direction by a clamping apparatus in opposed relation to the pressing apparatus in the opposite side thereof through the closed and aligned filter plate group to carry out the clamping of the filter plates and a closure plate in a short stroke. CONSTITUTION:A rod 5a extended by operating a hydraulic cylinder 5 from such a state that a filter cake is removed and filter plates are opened is lowered. By this operation, contractable and extensible members 6a, 6b are extended to move a pressing plate 8 along a rail 3 and filter plates 1 and filter frames 2 are pressed to one side to be closed. In this case, because end surfaces 6n of vertically directed ribs 6d, 6e formed to the contractable and extensible members 6a, 6b are contacted and the fulcrum points of extension and contraction are locked at a position slightly lower from the horizontal state of the contractable and extensible members, the pressing plate 8 is not pressed back by the repelling force generated to the filter plates 1. A hydraulic cylinder 9 is operated to press a clamp plate 10 through a rod 9a. By this mechanism, the filter plate 1c positioned at the rearmost position of the closed filter plate group is pressed to a plate opening direction being the side of a pressing apparatus S and, as the result, the filter plate group is clamped tightly.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for closing and tightening a P plate in an open-plate type off-shore engine using a P plate.

In the conventional off-shore passing machine of this type, the p-plates are pushed to one side by a pressurizing device of a hydraulic cylinder arranged on one side to close and align them, and then undiluted solution is injected into the off-shore pass. The distance to move this p-plate to one side is longer than the distance to open the p-plate to remove PH.
The rod must be long and have a large diameter, which increases the size of the cylinder device, resulting in a large equipment cost. In addition, the long rod takes up a lot of space.

Therefore, the present invention has been able to eliminate the above-mentioned drawbacks, and one of the present inventions will be explained below with reference to the drawings.

First, to explain the E-transfer machine used in the method of this example, in Figs. 1 and 2, 1 is an R plate, 2 is a P frame, and rollers are attached to arms 1a and 2a that protrude from each. 6. It is suspended so that it can be run on. These target boards 1. The r-frame 2 is engaged by the pawls 4 that are driven by the traction device N, and is opened. S is a closing plate suppression device, which is composed of a two-way hydraulic cylinder 5 whose lower end is fixed and swingable, and bending members 6a and 6b. The bending/stretching members 6a, 6b can be bent/stretched like a slider crank movement by interposing a connecting shaft 6c at the bending/stretching base at the center thereof, and the stroke thereof has a length enough to close the door panel group. Then, the cylindrical portion 5b attached to the tip of the cylinder rod 5a of the hydraulic cylinder 5 is fitted and coupled to the connecting shaft 6c, and one bending member 6a is connected to the machine base 7, and the other bending member 6a is connected to the machine base 7.
The other end of b is connected to a press plate 8 equipped with wheels 8a running on the rail 3. Note that the pressing plate 8 is the door plate 1b at the end.
It is placed adjacent to. K is a tightening device.

It is placed on the opposite side of the door panel group from the closing press device. The tightening device consists of two hydraulic cylinders 9, 9 fixed to the machine base 7, and the cylinder rods 9a, 9a + 7) serving as the driving bodies are arranged adjacent to the door plate 1c at the entire end of the cylinder rod. Tightening - Connected and fixed to the panel 10.

Note that the tightening board 10 also has wheels 10a and can move on the rails 6. Further, reference numeral 11 denotes a flexible tube for pouring the undiluted solution, through which the undiluted solution is sent to the door plate through the central hole 10b of the tightening board 1o.

Next, the method of this example will be explained. First, the I5 slag is removed and from the open state, the hydraulic cylinder 5 is operated to lower the extending rod 5a. As a result, the bending members 6a and 6b extend and move the pressing plate 8 along the rail 6, thereby moving the door plate 1. The p-frame 2 is pressurized and quickly closed to one side. Note that at this time, the ends 6n of the vertical ribs 6d and 6e formed on the bending and stretching members 6a and 6b are in contact with each other, and the bending and stretching fulcrum is locked at a position slightly higher than the horizontal position of the bending and stretching members. The pressure plate 8 will not be pushed back by the reaction force generated on the door plate 1. Then, the hydraulic cylinder 9 is operated to press the tightening plate 1o via the rod 9a. As a result, the door panel 1c located at the last position of the 7pj board group that was closed.
As a result of being pressed in the opening direction, which is the pressing device S side, the door panel group is tightened. Note that even if the hydraulic cylinder 9 is actuated to press the door plate 1C, the pressing plate 8 will not be pushed back because the bending member is locked and immovable as described above. In this state, the undiluted solution is supplied and passed through the ocean. As described above, according to the method of this example, first,
The first step is simply to press and move the door panels in the closing direction to close and align the door panels, and does not require expensive equipment costs for hydraulic cylinders. Then, in the second step, the door panels that have been aligned to close are tightened from the opposite side, but since the distance the door panels move during this tightening is short, a small hydraulic cylinder with a short rod can be used. Therefore, although a pressing device for closing the plate is required, a large hydraulic cylinder is not required, resulting in an extremely low equipment cost as a whole, and since a long cylinder rod is not required, it does not take up much space.

In addition, when a long cylinder rod is used to pressurize a group of door panels from one side to close them, the doors are often closed tilted in the same direction, but with this method, the inclination is reduced by pressing the door panels from the other side. Since the pressure is corrected so that the pressure is applied to each door plate, unevenness in the pressure applied to each door panel can be largely eliminated, resulting in a nearly uniform pressure force.

This prevents the conventional drawback of undiluted solution spewing out from the low-pressure area of the door plate.

Note that for plate opening after supercharging σ, the hydraulic cylinder 9
When the drive is released, the rod 9a is retracted and restored, and the hydraulic cylinder 5 is driven to extend the rod 5a, thereby bending the bending members 6a and 6b as shown in the imaginary line in FIG.

As a result, the pressing plate 8 and the tightening plate 10 move in the opposite direction to finish applying pressure to the door plate and door frame, so if the door plate is opened by moving the claw 4 of the traction device as in the conventional case, good. In this example, since the long bending members 6a and 6b are used as the pressing device for closing the plates, a sufficient gap for opening the plates can be provided.

In the method of this embodiment, the plate closing suppression device has the above-described configuration, but the method of the present invention does not require any other configuration. In addition, the state in which the door panels are pressed and moved in the closing direction and aligned in closing is not limited to whether the door panel group is weakly pressurized or not pressurized at all; Pressure is fine. In short, the present invention is a p-plate 2 offshore removal machine that opens the door plate and removes '/PR, and uses a closing press device provided on one side of the machine body to measure the length of the plate between the door plates necessary for removing slag. Or, after pressing and moving the door plate further in the closing direction to quickly close and align the P plate group, the door plate in the closed state is tightened by a device placed facing the pressing device on the opposite side of the door plate group. This is a method for closing and tightening door plates in a door plate double-passing machine, which is characterized in that the door plate group is strongly tightened by pressing the door plate toward the pressing device side in the opening direction.

Therefore, according to the present invention, the closing and tightening of the door plate are performed in separate processes, and the tightening of the hydraulic cylinder, which requires only a short stroke, can be done at a low cost. The equipment cost is extremely low because no configuration is required, and since the door plate is moved in the closing direction and then the tightening is moved in the opposite direction, the inclination of the door plate is corrected. It is very effective to be able to uniformize the pressure applied to the legs and achieve uniform leg passage.
