Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for processing processed products or samples at high temperatures in a pressure-resistant container.
The present invention relates to an autoclave that performs processing under high pressure, and particularly to a relatively large autoclave in which an operator enters a pressure-resistant container to carry in and out processed products.

An autoclave consists of a pressure-resistant container that allows substances to react at high temperatures and high pressures. Naturally, a large pressure-resistant container is used when processing relatively large aircraft parts, such as the wings of passenger planes.

In such a large autoclave, an operator must enter the pressure container to carry in and out the processed products.

By the way, if a worker is left inside the pressure vessel and the autoclave is operated after the vessel is sealed, the inside of the pressure vessel will be heated to a high temperature of 60 to 500°C, and high-pressure nitrogen gas etc. will be supplied, resulting in an extremely dangerous situation. is dangerous.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an autoclave that allows the operator to easily and quickly stop the operation of the apparatus even if the operator is trapped in a pressure-resistant container.

In order to achieve this object, the present invention provides an autoclave in which a heating source is disposed in a pressure-resistant container and high-pressure gas is supplied from a high-pressure gas supply source to treat processed products or samples at high temperature and high pressure. A filamentous body is stretched inside the container along its peripheral wall, an end of the filamentous body is connected to an operating part that issues a switch signal, and by pulling the filamentous body, a switch signal is emitted from the operating part. The heating source and the high-pressure gas supply source are configured to stop operating according to the switch signal.

Hereinafter, the present invention will be explained based on specific embodiments shown in the drawings.

FIG. 1 is a sectional view showing an example of the configuration of an autoclave according to the present invention, and FIG. 582 is an m-mIIA sectional view thereof.

In the figure, reference numeral 1 denotes a pressure-resistant container, which is composed of a substantially cylindrical container body 2 and an opening/closing door 3 that closes the opening thereof.

A heat insulating layer 4 is formed by disposing a heat insulating material on the inner walls of the container body 2 and the opening/closing door 3, respectively.

Further, inside the container body 2, a turbo fan 5 is disposed facing the opening/closing door 3, and a cylindrical Matsufuru 6 is provided which opens toward the suction port of the turbo fan 5 and the opening side of the container body 2. The container is arranged in a double structure, and a gas flow path 7 is formed between the container body 2 and the container body 2 .

8 is a high pressure gas supply source 18 (shown in FIG. 3), for example 2 to
Chinso gas pressurized to 20Kg/-.

A high-pressure gas supply port for supplying an inert gas such as argon gas into the pressure-resistant container 1; 9 a heating source such as an electric heater disposed along the inner wall of the container body 2; 10 a heat exchanger in the pipe 11; 12 is a door tightening ring that seals the opening/closing door 3, and 13 is a rail laid inside the container body. .

In the embodiment of the present invention, the filament W is stretched in the horizontal direction particularly along the peripheral wall inside the container body 2 of the pressure-resistant container 1.

This filament W is made of, for example, a wire whose surface is coated with heat-resistant coating, and one end thereof is fixed to the opening/closing door 3 side end of the Matsuful 6 disposed inside the container main body 2, and the other end is fixed to the side end of the opening/closing door 3 of the Matsuful 6 disposed inside the container body 2. It is connected to and stretched over the operating part 14 fixed to the outer wall of the main body 2, and is slidably supported by support pieces 15, 15- fixed to the inner wall of the Matsuful 6 at required intervals over its entire length. There is.

The operating unit 14 that connects the filamentous body W includes, for example, electrically conductive plate springs 16.16 arranged opposite to each other, and attached to the plate springs 16.16M at the ends of the filamentous body W. The insulating plate 17 is sandwiched between the plate springs 16 and 16 to separate the insulating plate 17 from between the leaf springs 16 and 16.
When the leaf springs 16 are released, the leaf springs 16 and 16 come into contact with each other and generate a switch signal.

In response to this switch signal, the operating section 14 is configured to instantaneously stop the operation of the heating source 9 and the high-pressure gas supply source 18, as shown in FIG. 3, and also cause the alarm device 19 to issue an alarm.

The above is an example of the configuration of the autoclave according to the present invention.Next, its operation will be explained. First, the door tightening ring 12
to open the door 3, and as shown in Figure 1, the trolley 2
A worker pulls the workpiece 21 placed on the rail 1.
3 and carried into the container body 2.

When the work of carrying in the processed product 14 is completed, the worker goes outside and
The opening/closing door 3 is closed again and sealed with the door tightening ring 12. Next, high-pressure nitrogen gas or the like is supplied into the pressure-resistant container 1 from the high-pressure gas supply source 18 through the supply port 8 .
The air inside the container is exhausted and the inside of the container is filled with high-pressure nitrogen gas, etc., and the heating tA9 is heated to a required temperature (for example, 60 to 5
00°C).

At the same time, the turbo fan 5 is activated to suck the gas inside the matsufuru 6, and the gas is passed through the gas flow path 7 into the opening/closing door 3 from the gas outlet formed at the side end of the opening/closing door 3. Feed it so that it sprays against the wall.

The gas in the Matsufuru 6 sucked in by the turbo fan 5 passes through the gas flow path 7 and is heated to a required temperature by the heating source 9, and then passes through the gas outlet formed opposite the opening/closing door 3. is sprayed against the inner wall surface of the opening/closing door 3,
The gas hits the inner wall surface and is circulated by forced convection so as to be reversed again inside the Matsufuru 6, and the heated gas heats the processed product 21 inside the Matsufuru 6 under high pressure and causes it to react.

By the way, in the event that the opening/closing door 3 is closed while the operator is trapped inside the autoclave, the operator should place his/her hand on the inner wall of the Matsuful 6 of the container body 2 and slide it in the circumferential direction. , put your hand on the striatum W as shown in Figure 2,
By pulling this filament W, the insulating plate 17 attached to its tip is pulled out from between the leaf springs 16 and 16' of the operating section 14.

This causes a short circuit between the leaf springs 16 and 16, causing a current to flow, and a switch signal is issued from the operating section (4) to instantly stop or stop the operation of the heating source 9 and the high pressure gas supply source 18 as described above. At the same time, the alarm device 19 issues an alarm.

As described above, according to the embodiment, even if an operator is trapped inside the pressure-resistant container 1, he or she can easily do so even in the dark, by simply placing both hands on the inner wall of the Matsuful 6 and sliding them in the circumferential direction. By simply pulling the filamentous body W, a switch signal is emitted from the operation unit 14, and the switch signal turns on the heating source 9 and the high-pressure gas supply source 18. Since the operation is stopped, accidents resulting in injury or death can be reliably prevented.

Note that the structure of the operating section 14 to which the filamentary body W is connected is not limited to that described above, and may be, for example, as shown in FIG. 4.

That is, FIG. 4 is an explanatory diagram showing another example of the operating part 14, in which a rotating shaft 22 is provided through the peripheral wall of the container body 2 at a predetermined position, and the rotating shaft 22 is extended into the container body 2. A rotating arm 23 is fixedly attached to the end of the rotating arm 23.
One end of the filament W is fixed to 4. A rotating arm 25 is fixed to the end of the rotating shaft 22 that extends outside the container body 2, and the rotating arm 25 is fixed to the rotating shaft 22 by pulling the filament W in the direction of arrow A. It is also possible to have a configuration in which, simultaneously with rotating the arm 23, the rotating arm 25 is rotated in conjunction with the rotating arm 23, and the tip portion 26 of the rotating arm 25 is brought into contact with the limit switch 27 to generate a switch signal. . In the figure, 28 is a gasket serving as a heat-resistant seal, 29 is a gasket holder, and 30 is a coil spring.

In short, the operating section 14 may be configured to issue a switch signal by pulling the filamentous body W.

Furthermore, in order to be able to easily locate the filamentous body W, it is preferable that two filament bodies W be provided facing each other as shown in FIG. 2, but it is of course possible to have one filament body W.

Furthermore, although not shown, the filament W may be stretched along the circumferential direction of the inner wall.

Furthermore, in the embodiments, an autoclave that uses an inert gas such as nitrogen gas as the high-pressure gas has been described, but an autoclave that uses high-pressure air may also be used.

As described above, according to the present invention, a filamentous body is stretched in a pressure-resistant container along its peripheral wall, an end of the filamentous body is connected to an operating section that emits a switch signal, and the filamentous body is By pulling the body, a switch signal is emitted from the operating section, and the switch signal stops the operation of the heating source such as an electric heater and the supply source of high pressure gas such as nitrogen gas, so the pressure-resistant container By simply sliding their hands along the peripheral wall of the pressure vessel, a worker trapped inside can very easily locate the filamentous body even in the dark and place his/her hand on it. Since the operation of the autoclave can be stopped by pulling it, there is an excellent effect of extremely high safety and the ability to reliably prevent accidents resulting in injury or death.
