Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a barrier membrane made of rubber-coated cloth or the like to keep ballast water and crude oil clean and prevent different types of liquids from mixing, such as in tankers or temporary underwater crude oil storage tanks. For containers categorized by , the method for attaching the diaphragm to the container and the diaphragm fixing fittings and hangers for containers, which are the fittings.

Although there are any of the following three methods for fixing the diaphragm end to the container, the present invention provides the diagonal clamp method.

■Vertical clamping method (see Figure 2) ■Horizontal clamping method (see Figure 2) ■Diagonal clamping method (see Figure 3) In Figures 1 to 3 above, 1 is the unit container. The waist end fixing positions 4 and 5 indicate crude oil and seawater, respectively.

Although the term "unit container" is used in the description, this is because generally several unit containers are combined, and of course, in the present invention, even one unit container may be used. The diagonal clamp method (2) of the present invention will be described below, but before that, the functions of the unit container when in use will be explained in FIGS.

Note that the diagonal clamp method has features such as smooth reversal of the diaphragm. In the figure, unit container ~ 2 is a diaphragm, e.g., rubber-covered cloth, 3 is a diaphragm end fixed position, 4' is B liquid (e.g., crude oil), 5' is A liquid (e.g., seawater), and 6 is A liquid. T indicates the outlet for B liquid, and 9 indicates the air hole for liquid tank A. In other words, as shown in Figures 1 to 6, the container is used for the following cycles 1 to 6. repeat.

(2) With valves 6, 7, and 9 open, liquid A (eg, seawater) is injected into the tank 5' using a pump or the like, and liquid B (eg, crude oil) is discharged from the tank 4'.

(See Figure 4) - This is, for example, the start of unloading crude oil from a vessel. @ Half of solution A is injected into pot 5', and solution B is injected into pot 4.
’ (see Figure 5) ■ Completely B
The state in which the liquid is discharged from the tank 4' (see FIG. 6) - This is, for example, when crude oil has been completely unloaded from the ship's supply.

@ With valves 6, 7, and 8 open, pour liquid B from valve 7 4'
and drain A liquid from the tank 5'.

(See Figure 6) - This is, for example, the start of loading crude oil into the ship's dock. @ Half of liquid B is injected into tank 4' and half of liquid A is discharged from tank 5' (see Figure 6).

6. A state in which liquid A is completely drained and liquid B is 100% injected into the tank 4' (see Fig. 4) - This is the case, for example, when the lance is fully loaded with crude oil.

Now, the size of a container equipped with such a corneal membrane is extremely large, and the size of a unit container is, for example, 19 skins x 19 bones x 33 skins, and the size of the diaphragm to be clamped is about 1,500 pillows.
It weighs about 12 tons. Therefore, clamping the septum is extremely difficult.

The present invention is a method for attaching a diaphragm to a container that solves this problem.The diaphragm is unfolded so that the fixed part of the diaphragm is exposed outside. ``Hang the diaphragm so that the diaphragm fixing bracket is at the corner membrane fixing point of the container''. Furthermore, the diaphragm fixing metal fittings of the present invention are used directly in the above method; These are illustrated by the following description and illustrative drawings.

The present invention will be described in detail with reference to the seventh to turtle diagrams illustrated below.

{1) Expand the diaphragm so that the fixed part is exposed outside. For example, number one? When folded as shown in the illustration, the fixing part will be exposed along the outer periphery.

Reference numeral 2 indicates the diaphragm body, for example, rubber-coated cloth, and 2a indicates the fixation site layer.

Note that FIG. 7A is a perspective view of the shape shown when the diaphragm is attached to the container fixing part, and when folded along the imaginary line, it becomes the shape of the opening in FIG.

That is, as shown in Fig. 7A, there are two quadrangular planes ABFE and CDEF and
A quadrilateral ABCD is made up of two triangular planes AD8 and BCF.
Bend the open corneal membrane from the part indicated by the two-dot chain line.

The way to fold the square plane ABFE is to fold it inward along the chain line of IJ, and when it is folded flat,
As shown in Figure 7, the bending line of IJ should be on the line connecting G and day. The triangular plane ADE is a two-dot chain line A
Bending from G, DG, EG, IG, how to fold is A.
G, DG, and EG are bent inward and IG is bent outward, so that when folded flat, the bending line of GI coincides with the bending line of bent IJ, as shown in the opening of FIG. Triangular plane BCF is also bent in the same manner as above. Thus, the diaphragm shown in FIG. 7A can be folded into a rectangular plane as shown in FIG. The end edge ABCD is attached using the diaphragm fixing fitting 10, but because the end edge is partially wrapped around the rod and attached, the position where the membrane is fixed by the diaphragm fixing fitting 101 is slightly inside the edge of ABCD. This position is designated as 2a.

■ Attach the diaphragm fixation fitting to the diaphragm fixation site layer. For example, as shown in FIG. 8, the diaphragm fixing fitting 10 is attached to the fixation site layer 2a of the diaphragm 2.

(See {8) below) 11 is a base plate 33 for fixing the diaphragm fixing fitting 10 and the diaphragm 2, which is tightened with a nut.
12 is a bolt hole for attaching the corneal membrane fixing fitting 10 to the container, and bolt 3 is a screw hole for fixing the diaphragm fixing fitting 10 to a hanging tool (see [3', [4}] below). , 11' is the hole through which the bolt 11 passes, 34 is the rod, 3
1 is a sticker sheet. Figure 9 shows the diaphragm fixing fitting 1 in advance.
An example of the position to install 0 is shown, leaving the four corners 10f
Attach the diaphragm-fixing metal stencils to the four sides shown in .

14a is a workbench that constitutes a part of the hanging tool. Turtle 4b is a diaphragm fixing vulgar.

'31 Attach the bulkhead fixing bracket to the hanging fixture.

For example, as shown in FIG.
The diaphragm fixing fitting 10 is fixed through the screw hole 13 illustrated in the figure. 14c is a stopper for keeping the angle of the diaphragm fixing metal constant. The stopper 14c is fixedly attached to the affirmative membrane fixing jig 14b, and the tip of the stopper is designed to touch and be directly attached to the base plate 33. As illustrated in FIG. 9, the workbench 14a and the diaphragm fixing jig 14b constituting the hanging tool are suspended by a crane or the like inside the four sides of the diaphragm along the angle membrane fixing attachment position of the diaphragm. '41 Suspend the diaphragm into the container. For example, as shown in FIG. 11, the cornea 2 is suspended together with the hanging tool 14 by the crane 16 inside the main part 1' of the unit container as shown below, and the position of the bolt 17 for fixing the diaphragm fixing fitting to the container is Then, the hanger 14 is moved horizontally toward the wall of the container to match the position of the hole 12 illustrated in FIG.

The main part of the unit container has a barrier opening 18 that is cut so as not to cross the diaphragm fixing position of the container.
If this is manufactured and positioned with the closing portion 18 facing upward as shown in FIG. 11, the diaphragm can be easily suspended from above. At this time, if you dig into the ground as shown in the figure, the diaphragm fixing position will be lowered, making it easier to work. ■ Attach the diaphragm fixing fittings to the container.

By the method exemplified in [4} above, as illustrated in FIG. 12, the bolt 7 provided on the container is passed through the hole 12 of the diaphragm fixing fitting, and the nut 28 is attached to the bolt 17 through the hole 14d of the diaphragm fixing jig 14b. The diaphragm fixing fitting 10 is attached to the main part 1' of the unit container by tightening the fitting.

(See section 8 below) Remove the bolts 15 illustrated in FIG. 10 from the diaphragm fixing fitting 10 to separate the diaphragm fixing fitting 10 and the diaphragm fixing jig 14b. {6} Fix the remaining four corner ribs.

Fix the remaining diaphragms at the four corners from above the workbench 14a.

'71 Form a unit container.

As shown in Figure 13, connect the missing part 1'' of the container with
Then, the main part 1' of the unit container is welded, for example, to form the attached unit container.

In the figure, 2 river water, 21, indicates water spraying, which is for protecting the diaphragm 2 from welding sparks and heat transfer. '8} The details of attaching the diaphragm fixing fitting mentioned in {2} and [5} above to the container are as follows, for example.

Fixing bolts are fixed at necessary locations on the portion of the container 1 where the femoral membrane is to be fixed. Linear packing such as round bran rubber 32
Place it all over the area where the diaphragm is to be fixed. A sealing sheet 31 made of rubber cloth is placed on top of it so that it is held by the fixing bolts 17, and a base plate 33 is placed on top of it.
put Hold the end of the diaphragm 2 made of an elastic material such as rubberized cloth with a sealing sheet 3 with a clamping bar (fixing metal fitting) with a rod 3 made of a metal bar, etc. The clamping bar Q' also has a central member provided with at least one hole and an arm member extending from the central part, but the arm member is also smooth. Further preferably, another arm member 38 is provided on the opposite side of the arm member 38 from the center village. This clamping bar is provided with the three fins of the foot to press against the base plate.
Arm member 381 of the wing■ ``Hold down the thing wound back onto the rod together with the corneal umbrella and the shiw lucid set.'' Push in the fixing bolt hole 2 of the clamping bar officer Q. ``Tighten the nut with the nut. The ends of the diaphragm crab and the 8 seal sheets can be further covered over the clamping bar jutsuru, or for example, fixed to one side of the taramping bar on the drive screw narrow wing. The seal sheet is first sealed in a linear manner with a linear packing material 32, and then sealed in a planar manner with a base plate 33.

This also creates a complete seal between the mounting bracket and the container. Since the corneal diaphragm 2 and the seal sheet 3 are overlapped and pressed together by the clamping bar 10, a complete seal is created between the diaphragm and the mounting bracket. Since the two sheets are overlapped and cover the clamping bar K0, even if the diaphragm 2 moves,
Damage caused by fixtures is prevented. According to the method of the present invention as described above, even large-weight, large-volume rattan membranes can be easily attached to containers.

Furthermore, according to the septum waist fixing fitting of the present invention or the septum attaching hanger of the present invention, the above-mentioned attachment work can be made more convenient.
