Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a fire extinguisher tool,
In particular, the present invention relates to a fire extinguisher used for the initial extinguishing of a so-called tempura oil fire, which uses oil used for cooking fried food such as tempura as a fire source.

[0002]

2. Description of the Related Art "Konoro" is one of the top causes of fires in so-called building fires (first place in the 1996 White Paper on Firefighting), 80% of which is "Tempura oil".
Due to. If you continue to heat the tempura oil without weakening the heat, it will ignite spontaneously at about 350 ° C to 370 ° C, leading to a fire in the worst case. It is possible to extinguish with fire.

[0003]

In a building fire, a fire extinguisher is usually used for initial fire extinguishing regardless of the cause of the fire. However, as can be seen from repeated fire extinguishing drills, it is difficult to use a fire extinguisher to carry out appropriate fire extinguishing activities unless you are used to handling fire extinguishers on a daily basis.

For example, it may be time-consuming to pull out the safety plug of the fire extinguisher and firmly grasp the lever. In general, it is said that ordinary people cannot extinguish a fire when it burns to the ceiling, and it is said that initial fire can be extinguished within a few minutes. Therefore, if it is noticed a few minutes after the ignition, it may not be possible to extinguish the fire and prevent the spread of fire due to the troublesome operation.
Also, if you do not know where to direct the fire extinguishing agent, or the duration of injection of the extinguishing agent (for example, about 15 seconds with a fire extinguisher with a height of about 40 cm and an amount of extinguishing agent of about 1.5 kg) Sometimes you can't extinguish a fire extinguishing agent because you don't know. Furthermore, the fire source of the tempura oil fire is usually a tempura pot in which the tempura oil is poured, so a place near the fire source (for example, a position 1 to 3 m away)
When fire extinguishing agent is sprayed from, the fire extinguishing agent is vigorously ejected, which may cause the fire to scatter or the pot to be turned upside down, which may cause burns or burns.

The present invention has been made under the background as described above, and the method of use for extinguishing a fire is simple and the fire extinguishing agent can be quickly and surely injected into the fire source. It is an object of the present invention to provide a fire extinguisher for a tempura oil fire that enables initial fire extinction.

[0006]

In order to solve such a problem, the fire tool of the present invention is one in which a fire extinguishing agent is contained in a container, and the fire extinguishing agent is put out of the fire and extinguished the fire outside the container. A fire extinguishing tool for releasing a medicine, wherein a container comprises a bag made of synthetic resin for accommodating the fire extinguishing agent, and an exterior body having a layer made of a metal foil or film for covering the bag. The fire extinguishing agent contains a pressurizing component which is heated in a state of being thrown into the fire source and expands to increase the pressure in the bag body.

The metal foil or film of the outer package is preferably an aluminum material such as JIS1003 or a film of a component corresponding to the composition of these aluminum materials. This is because it is suitable in terms of heat conductivity. Further, the thickness thereof is preferably such a thickness that can secure a quick heat transfer property and can secure a function of protecting the bag body from heat for a certain period of time. From the viewpoint of ensuring these functions, for example, 1 μm or more and 30 μm or less is preferable. Then, it is preferable that a synthetic resin material is adhered to the aluminum foil or film. This can prevent the foil or film from cracking. Examples of the synthetic resin material include polypropylene film (CPP film), propylene-ethylene block copolymer or polyethylene terephthalate film (PET film), nylon film and the like. The bag may be adhered to an aluminum foil or film to prevent cracks. Further, if the bag body is brought into close contact with the exterior body, there is an advantage that the heat transfer property is improved. The thickness of the entire outer package is, for example, 2 mm to 10 μm.
It is about m. This is because if it is too thick, it takes a long time to release the extinguishing agent. Also, if it is too thin, the time until release may become unstable.

This fire extinguisher is easy to use. When used for the initial fire extinguishing of a tempura oil fire, all that is required is to put this fire extinguisher together with the container into a frying tempura pot. Therefore, it is possible to quickly and surely execute the fire fighting activity. It also prevents the pot from being turned over. Since it is easy to use, no prior training is required.

When the fire extinguisher is dropped in the tempura pan, the tempura oil heats the container and the extinguishing agent in the container, and the pressurized component in the extinguishing agent expands. Then, the internal pressure of the bag increases, the container is broken, and the extinguishing agent is vigorously discharged from the container in the form of foam. The fire extinguishing agent thus released promptly and surely leads to a fire of the oily starch oil.

For example, in the case where the container is composed only of a bag made of synthetic resin, when the fire extinguisher is put into the tempura oil heated to 350 ° C. or higher, the bag is compressed before the pressurized component in the fire extinguishing agent is expanded. The body melts, the internal pressure of the bag does not rise,
Extinguishing media may not be released vigorously. On the other hand, if you use a metal container with a melting point higher than the temperature of tempura oil, the container will not melt, but after the fire extinguisher is put in, the container will quickly break with the internal pressure of the container increased Is difficult to do.

In this respect, since the fire tool of the present invention uses the container provided with the exterior body having the metal foil or film layer, the heat of the tempura oil may cause the bag body to melt early. Absent. Further, since the fire extinguishing agent is contained in the bag made of synthetic resin, the fire extinguishing agent does not leak even when subjected to bending force or shearing force. After the container of the fire tool is put into the tempura oil, it is rapidly broken while the internal pressure of the container is sufficiently increased, and the fire extinguishing agent in the container is smoothly released into the tempura oil with a certain amount of force. If the fire extinguishing agent is vigorously released into the tempura oil, the fire extinguishing agent quickly spreads throughout the pot, and the fire can be extinguished in a short time. And since it is released smoothly, it is possible to prevent the flame from temporarily increasing due to the release of the extinguishing agent. Further, according to the present fire extinguisher, the fire extinguishing agent can be released in a foamed state, so that a higher fire extinguishing action can be obtained. It is considered that the reason for the foam state is that the fire extinguishing agent is released from the crevice of the container, and when released, the fire extinguishing agent is heated and rapidly released from the state where the pressure is increased.

Further, as the exterior body, one having a plurality of openings for releasing the fire extinguishing agent in the bag body to the outside may be used. The usage and the process of extinguishing the fire are the same as those of the fire extinguisher described above. However, in the case of this fire extinguisher, the bag body is likely to be heated because the exterior body has an opening or the like. Therefore, the fire extinguishing agent is released from the bag earlier than the fire extinguisher described above. As a result, the pressure inside the bag does not rise, so there is no momentum at the time of release. However,
Since the fire extinguishing agent is released to the tempura oil side through the opening of the exterior body, it is surely foamed when passing through the opening.
It is considered that a high fire extinguishing effect can be obtained by surely forming the foam. From this, as in the case of the above-described fire extinguisher, it is possible to promptly and surely lead the combustion of the starch oil to extinguish the fire.

Examples of the exterior body having a plurality of apertures include a wire net and a thin plate having a large number of apertures formed by punching or the like. In the case of a net, the aperture means the space of the mesh opening. Examples of the material include stainless steel such as SUS304 and 316. In addition, a material having heat resistance (assuming a tempura oil of about 350 ° C. as a heat source) such as carbon fiber and having flexibility if possible may be used. By disposing the exterior body made of these materials on the outer side, the inner side or the inner side of the bag body, the fire extinguishing agent can be released into the tempura oil while foaming. The size of the mesh of the mesh can be selected as necessary because it has the effect of making it foamy according to its size. For example, in the standard sieve standard, the mesh size is 0. The thickness is preferably 0.032 mm or more and 2 mm or less, and more preferably 0.45 mm or more and 1.18 mm or less from the viewpoint of more reliably forming bubbles. The weaving method is not particularly limited, but a plain weave is preferable from the viewpoint of durability, and a single-stranded wire network, a co-twisted wire network or a crimp weave other than the plain weave is preferable from the viewpoint that the fire extinguishing agent is more easily foamed. . In the case of a thin plate with holes, the size of the holes is
According to the size of the mesh opening. Also, the shape of the opening is round,
Various shapes such as triangles and polygons such as squares are possible.

By the way, the synthetic resin material used for the bag is preferably a flexible synthetic resin material. If a synthetic resin having flexibility is used, the fire extinguishing agent can be easily accommodated in a sealed state by heat sealing. Further, there is also an advantage that containers of various shapes and capacities can be easily manufactured. By changing the shape of the container, it is possible to change the heat-receiving area when the fire extinguisher is put in the tempura oil.Therefore, the fire extinguishing agent can be released without adjusting the amount and composition of the extinguishing agent by selecting the shape. You can adjust the time.

A PET film is particularly preferable as the synthetic resin material used for the bag. It is considered that the PET film has a preferable behavior of heat shrinkage in a state of being put into the tempura oil and heated, as a material of the bag body existing inside the aluminum foil or the film. The thickness is
Although it varies depending on the form of the outer package, it is preferably 50 μm or less in order to ensure the heat transfer property and 5 μm or more in order to ensure the strength. The synthetic resin used for the bag is not limited to a single film and may be a laminated film such as a double film. It is considered that the use of the laminated film more reliably prevents the sudden release of the fire extinguishing agent and the sudden release of the fire extinguishing agent from causing a sudden increase in flame.

A metal can may be used as a container for containing the fire extinguishing agent. In this case, a through hole through which the fire extinguishing agent is discharged is formed in the can, and a partition member having a plurality of openings through which the fire extinguishing agent discharged through the through hole is passed is installed. As the material of the can, the temperature of the tempura oil (for example, 3
For example, aluminum materials (JI
S3004). In the case of a fire extinguisher using a can as a container, the container may be put into the tempura oil which is the origin of the fire when used. However, in the case of this fire extinguisher, since the container does not melt or break, the extinguishing agent discharge place is limited to the through hole initially formed. Therefore, if there are few fire extinguishing agent discharge ports, the release direction of the extinguishing agent is likely to be biased, but since the number is small, the momentum at the time of release can be secured, so the effect of rapidly spreading the extinguishing agent over the entire pan Is obtained.

Examples of the partition member include a net used as an exterior body of the above-described fire extinguishing tool and a thin plate having a large number of openings formed by punching. When using these, it is preferable to determine the conditions such as opening in accordance with the above range. It should be noted that if the fire-extinguishing agent is released quickly, the fire-extinguishing agent is more likely to be foamed when discharged through the opening, so that a higher fire-extinguishing action can be obtained in this respect.

When the outer casing is an aluminum can, its thickness is preferably 0.8 mm or less in order to secure heat transfer.
In order to secure the strength, 0.5 mm or more is preferable. When the case is a can, the case has a certain strength, so it is not always necessary to cover the case with a synthetic resin material, but a resin layer may be provided for preventing oxidation. It should be noted that well-known techniques such as a method for producing canned drinking water can be used for manufacturing cans, and a description thereof will be omitted. The number of through-holes is not particularly limited, but it is preferable that it is small from the viewpoint of surely preventing the extinguishing agent from leaking.
For example, it is about 1 to 5.

When the can is used as a container, a sealing means for sealing the through hole may be provided in order to surely prevent the extinguishing agent from leaking in a state in which the can is placed as a container. The sealing means may be, for example, one that is fitted into the through hole such as a plug, or one that is screwed into the through hole that is projected like a neck, such as a screw-type lid. Further, a synthetic resin film or the like may be attached to the portion of the through hole for sealing. If the sealing means is, for example, a material that can be opened with a finger, or a material that is opened by the heat when thrown at the fire source or the internal pressure in the can, it is possible to throw it directly at the fire source without removing the sealing means. it can. If this is not the case, the sealing means should be removed or removed before use for extinguishing fire.

Finally, as a fire extinguishing agent, it is possible to use a conventionally used one, for example, an extinguishing agent containing ammonium carbonate or sodium carbonate as a main component. Further, a component contained in the fire-extinguishing agent, which is heated and expanded in a state where the fire extinguisher is thrown at the fire source, and a preferable component as a pressurizing component for increasing the pressure in the container is, for example, a saturated sodium carbonate solution. Another example is ammonium phosphate. After the fire is extinguished, it is preferable to include a surfactant in the fire extinguishing agent, because the effect of preventing reburning is obtained by covering the oil surface.
