Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a high-pressure container device, and is used in a gas pressure impregnation device, a hot isostatic pressurization device, a cold isostatic pressurization device, and the like.

(Prior Art) A high-pressure container device must seal the upper and lower openings of a cylindrical high-pressure container with an upper lid and a lower lid, and in addition to the sealing, it must also support axial force due to the pressure inside the container.

Therefore, we have developed a model that attaches the upper and lower covers with a screw structure.
There is a type in which the upper and lower lids are fitted together via an airtight seal, and the axial force is carried by a support frame that engages with the lid.From the viewpoint of productivity and safety, the support frame is preferable to the screw structure. The type is advantageous.

However, in the support frame type, there are members that protrude outward in the axial direction from the axial center of the container, such as a push rod for inserting and removing the product.
It was difficult to provide a cylinder for opening the lid.

Therefore, in Japanese Utility Model Publication No. 62-3676, the support frame that carries the axial force is constructed as a divided body of a first support frame and a second support frame, and each of the first and second support frames has an upper and lower cover. The engagement position is engaged in the radially outer region of the upper and lower lids, and the position can be freely changed between this locked position and the position where they are separated from each other. A high-pressure container device has been proposed that is provided with a protruding member to enable product removal.

(Problems to be Solved by the Invention) However, in the prior art described in the descriptive publication, the member projecting outward in the axial direction itself is a driving body such as a telescopic cylinder, so the device becomes bulky. However, it has been difficult to ensure a sufficient vertical stroke for loading or unloading objects or products to be processed.

In addition, the descriptive publication discloses a device in which a driving body is provided on the outside of the container, but in this case, the object to be processed or the product, etc. cannot be raised or lowered within the closed container, Therefore,
It was difficult to apply it to gas pressure impregnation equipment.

The present invention was devised in view of the problems described above, and by making the actuator actuable in the axial direction in a sealed room, gas pressure impregnation equipment, HIP,
The purpose is to provide a high-pressure vessel device suitable for CIP and the like.

(Means for Solving the Problems) The present invention provides a cylindrical high-pressure container l, an upper lid 2 and a lower lid 3 for sealing the upper and lower openings of the high-pressure container l, and the upper and lower lids 2, 3.
a support frame 4 that carries an axial force acting on the
In a high-pressure container device in which the support frame 4 is movable between a pressurized position and a retracted position, the stated purpose was achieved by taking the following technical measures.

That is, the present invention provides for the upper lid 2 at the axial center of the high pressure container l.
