Description

[Detailed description of the invention] i99 purpose of invention Industrial applications This invention relates to a high pressure vessel.

Conventional technology High-pressure containers (autoclaves) require a large opening in the main body to facilitate internal cleaning and inspection, especially when handling solid or viscous substances. However, it is complicated to attach and remove the bolts, and the higher the pressure, the larger the flange and the number of bolts, so the weight of the flange is smaller than the weight of the main body excluding the flange. is many times larger, making it inconvenient to handle.

In order to solve these drawbacks, as shown in FIG.
The substrate 3 and the top plate 4 are inserted and installed laterally into a frame 6 which is connected by a plurality of supports 5, and internal pressure is applied to the cylindrical high-pressure container body l so that the lid 2 is inserted into the top plate 4 of the frame 6. A type of high-pressure container that is pressed against the inner surface and fixed has been proposed.

The space between the piston-shaped lid 2 and the cylindrical high-pressure container body 1 is normally sealed with an O-ring as shown in the figure.

The bottom of the cylindrical high-pressure container body 1 may be integrated with the cylindrical high-pressure container body as shown in FIG. 12, or may have a piston-shaped bottom cover inside.

The frame 6 has the strength to support the lid 2 pressed by the pressure inside the cylindrical high-pressure container main body 1, and has a structure that allows the cylindrical high-pressure container main body 1 to be easily inserted into and removed from the frame 6. , the strut 5 is a cylindrical high pressure vessel main body l
One or more supports can be removed so that they do not get in the way of taking things in and out.

Although such a high-pressure container solves the above-mentioned drawbacks of the conventional autoclave, the cylindrical high-pressure container main body 1 is installed correctly in a predetermined position within the frame 6, and the lid 2 presses the top plate 4 evenly. If this is not done, it will not be possible to fully demonstrate its strength as a high-pressure container.

However, when using such a high-pressure vessel, it is necessary to frequently attach and detach the cylindrical high-pressure vessel body for internal cleaning and inspection, and depending on the purpose of use, cylindrical vessels with different internal volumes and diameters are often used. The high-pressure vessel body may be switched and used, but it is important to properly install the vessel at a predetermined position within the frame each time such frequent attachment and detachment or switching to various cylindrical high-pressure vessel bodies with different diameters is required. This is essential to ensure the pressure resistance of the container.

In addition, even if the cylindrical high-pressure container body is removed from the frame after being used at high pressure after the pressure is released, the lid 2 is often stuck to the inner surface of the top plate 4 and cannot be easily removed. That's a problem.

The purpose is to provide a high-pressure container that is easy to attach and detach.

The structures specifically listed above allow the cylindrical high-pressure vessel body to be restrained in a predetermined position within the frame, making it possible to frequently attach and detach the cylindrical high-pressure vessel body and switch to various cylindrical high-pressure vessel bodies with different diameters. However, there is another problem with conventional frame-internal high-pressure vessels, namely, when the pressure is released and the cylindrical high-pressure vessel body is removed from the frame after being used at high pressure. A solution to the problem that the lid 2 often sticks to the inner surface of the top plate 4 and cannot be easily pulled out even when trying to take it out will be described.

That is, a mechanical means is provided for pushing a piston-shaped lid housed in the cylindrical high-pressure container body into the cylindrical high-pressure container body.

If the port 42 is pulled up again from the state shown in FIG. 9B, a gap will be created between the lid 2 and the top plate 4, so that the cylindrical high-pressure container body l can be easily pulled out laterally from the frame 6. .

10A and 10B show that a piston 44 is installed inside a cylinder 43 provided on the top plate 4 of the frame.
By feeding pressurized fluid into the cylinder 43, the piston 44 is projected and the lid can be pressed. In FIG. 10A, the piston 44 is pulled up and the lid 2 of the cylindrical high-pressure container body 1 is placed on the top plate. Figure 10B shows the state in which the cylinder 4 is crimped (the state in which the cylindrical high-pressure container main body L is used).
3 shows a state in which pressurized fluid is fed into the container 3, the piston 44 is made to protrude, and the piston-shaped lid 2 is pushed into the cylindrical high-pressure container body 1. If the piston 44 is pulled up again from the state shown in FIG. 10B, a gap will be created between the lid 2 and the top plate 4.

What is shown in FIGS. 11A and 11B is a structure in which the top plate 4 of the frame is movable along the pillars 5, and M2 can be pressed by moving the top plate 4 in the direction of the board 3. In Fig. 11A, the top plate 4 is in the upper position and the lid 2 of the cylindrical high-pressure container main body l is crimped to the top plate 4! Fig. 11B shows a state in which the top plate 4 is pushed down and moved toward the substrate 3, and the piston-shaped lid 2 is pushed into the cylindrical high-pressure container body 1. It shows. If the top plate 4 is pulled up again from the state shown in Fig. 11B (the state shown in Fig. 11A is automatically restored by the action of the spring 51, if the pressing force on the top board 4 is removed), the gap between M2 and the top board 4 Since a gap is created in the frame 6, the cylindrical high-pressure container main body l can be easily pulled out laterally from the frame 6.

A cylindrical high-pressure container body l with a piston-shaped lid 2 inside is installed in the frame 6, and internal pressure is applied to the cylindrical high-pressure container body l to press the lid 2 against the inner surface of the top plate 4 of the frame 2. Lid 2
is fixed, and the cylindrical high-pressure container body l can be used at high pressure.

When inserting the cylindrical high-pressure vessel body 1 into the frame 6, the apparatus of the present invention can restrain the cylindrical high-pressure vessel body 1 at a predetermined position within the frame 6, thereby preventing frequent attachment and detachment of the cylindrical high-pressure vessel body. When switching to various cylindrical high-pressure vessel bodies having different diameters, it becomes easy to correctly install the vessel at a predetermined position within the frame.

When the cylindrical high-pressure container main body l is removed from the frame 2 after being used at high pressure, if the lid 2 is in close contact with the inner surface of the frame 2 and cannot be easily removed, the piston-shaped lid built into the cylindrical high-pressure container main body may be removed. A gap is created between M2 and the top plate 4 of the frame by using a mechanical means for pushing the cylindrical high-pressure container body 1 into the cylindrical high-pressure container body 6, and the cylindrical high-pressure container body 1 can be easily extracted from the frame 6.
