Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fire extinguisher for extinguishing the combustion of tempura oil placed in a pot.

[0002]

[Prior art]

 Fire extinguishers and aerosol-type simple fire extinguisher are examples of fire extinguishing tools that suppress or extinguish the combustion caused by overheating of tempura oil in a pan. If you do not have a fire extinguisher or an easy aerosol-type fire extinguisher nearby, you can suffocate with a cushion or bath towel.

In the case of a fire extinguisher, although a fire extinguisher that uses a powder fire extinguisher is extinguished once, there is a risk of reigniting due to the heat of the pot. Although it is possible to prevent a re-ignition by using a fire extinguisher that uses a strengthening liquid fire extinguisher, when the fire extinguisher is radiated close to the pot, the overheated tempura oil scatters and the operator Risk of burns.

If the aerosol type simple fire extinguisher is not adapted to the burning of the tempura oil, on the contrary, there is a problem of promoting the burning. Furthermore, the method of putting a cushion or bath towel on the tempura pan to extinguish the fire by suffocation has the problem that the operator must approach the pan, which may cause burns due to radiant heat or flame.

[0005]

[Problems to be solved by the device]

 It is an object of the present invention to provide a fire extinguisher capable of safely supplying a fire extinguishing material into a pan from a position remote from the pan and reliably extinguishing the fire within a few seconds after the supply.

[0006]

[Means for Solving the Problems]

 The means for solving the problems according to the present invention is to enclose a calcined diatomaceous earth grain with an apparent unit density of less than 1 g / cc with a porosity of 50% or more in continuous vents and an aqueous solution of alkaline metal salt that exhibits an alkaline reaction. A fire extinguisher for burning tempura oil, which comprises a flammable, water-impermeable capsule, a flammable container that encloses the above-mentioned diatomaceous earth fired grains and a capsule, and a support rod that is attached to the container and extends outside the container. . Further, the diatomaceous earth-baked grains used are those treated with lipophilicity.

The reason why the diatomaceous earth fired particles are subjected to lipophilic treatment is that when the permanent place of the fire extinguisher is a place where water is used such as in a kitchen, the diatomaceous earth fired particles absorb water and moisture, and the tempura oil is used. Since the absorption effect of oil may be reduced, it is necessary to repel water and moisture and maintain the oil absorption effect.

The diatomaceous earth fired particles used as a fire-extinguishing material in the present invention extrude diatomaceous earth through a circular hole to a thickness of 1 to 10 mm, and naturally fold it while drying it with a dryer to an appropriate length. Since it is a fired product, its length is not constant in some ways and it may be broken during transportation and handling, so the ratio of length to diameter (aspect ratio) is mostly 0. If it is about 0.5 to 3, it can be used. The lipophilic treatment can be carried out by a known method such as impregnating diatomaceous earth fired particles with silicone oil and drying.

[0009]

[Action]

 In the present invention, as the diatomaceous earth fired particles, those having a porosity of the continuous ventilation holes of 50% or more, preferably 60% or more and an apparent unit density (measured value of a single particle) of less than 1 g / cc are used. This is because, when the ventilation holes are less than 50% and the apparent unit density is 1 g / cc or more, the amount of the tempura oil absorbed is small and it becomes difficult to quickly absorb the tempura oil into the ventilation holes. The bulk density (density of aggregates of grains) of diatomaceous earth fired grains is 0. It is preferably about 55 to 0.60. When diatomaceous earth fired grains are treated with lipophilic oil, the affinity with tempura oil increases and absorption can be accelerated.

The tempura oil absorbed in the calcined diatomaceous earth grains does not burn, but the oil present on the surface or interface burns. Therefore, an aqueous solution of alkali metal salts that exhibits an alkaline reaction is enclosed and is flammable and permeable. A non-active capsule is used to extinguish a fire by contacting an oil with an aqueous solution of an alkali metal salt or the like, which burns and exhibits an alkaline reaction. Aqueous solutions of alkali metal salts, etc. that exhibit an alkaline reaction are applicable to the Ministerial Ordinance (September 17, 1964, No. 28 of the Ministry of Autonomy, revised October 17, 1973, No. 29 of the Ministry of Self-Government). No.) that complies with the standards for enhanced liquid fire extinguishing agents. The reason why an aqueous solution of an alkali metal salt or the like that exhibits an alkaline reaction is used in the present invention is that the fire can be extinguished more reliably than the neutral fire extinguishing agent.

The material of the capsule may be any material that has no water permeability and can store an aqueous solution and can burn the aqueous solution to the outside. Therefore, waterproof paper or plastic film can be used. This capsule may be one in which the amount of the aqueous solution necessary for extinguishing is all put in, or a container or bag containing soy sauce, sauce, etc. attached to a commercially available bento, or diatomaceous earth baking It is also possible to disperse several particles between the grains and enclose them.

Any container may be used as long as it contains diatomaceous earth fired particles and capsules and has strength and flammability for attaching a supporting rod, and paper or plastic can be used. The outer shape of the container is arbitrary, such as a cylindrical shape, a spherical shape, a prismatic shape, and a paper bag shape. The support rod is attached so that the container can be safely loaded into the pan from a position away from the pan containing the tempura oil, such as pipes made of iron, stainless steel, aluminum or hard vinyl chloride. Use a stick. The length may extend from the container outward by about 50 to 60 cm. The support rod may be one that can be expanded and contracted for convenient storage, or a simple rod that cannot be expanded and contracted.

【Example】

 FIG. 1 shows an embodiment of the present invention, in which 1 is a diatomaceous earth fired cell having a porosity of 60%, an apparent unit density of 0.6 g / cc, a diameter of 2 mm and an aspect ratio of 1 to 3. It is a grain. Reference numeral 2 is a capsule in which an aqueous solution 30 cc of an alkali metal salt or the like exhibiting an alkaline reaction is wrapped in a polypropylene film having a thickness of 0.02 mm. Reference numeral 3 is a container of hard vinyl chloride having a thickness of 0.1 mm and encapsulating 500 ml of diatomaceous earth firing and a capsule 2.

The container 3 is composed of pipes of large and small diameters so that it can be expanded and contracted using a pipe made of hard vinyl chloride, and the support rods 4 in which the small diameters are sequentially inserted into the large diameters are The large outer diameter portion is attached to the container 3 by using an attaching piece or an adhesive. The support rod 4 is provided with a notch at an end of a pipe to be inserted into another pipe, and a spring and a locking piece provided so as to be pressed against the inner surface of the outer pipe by the spring. The inner pipe is prevented from coming out of the outer pipe by fitting the locking piece into the annular groove provided on the inner surface of the end in the direction of pulling out the inner pipe.

[0015] In a tempura pot with a diameter of 30 cm and a depth of 7 cm, 500 ml of corn vegetable oil for tempura was overheated to ignite the oil, and when the flame reached a height of 1 m, the above fire extinguisher was extended. Holding the end of the support rod 4, the container 3 was inserted into the fryer. Two seconds after the container 3 was placed in the tempura pan, the height of the flame became 30 cm, and after 5 seconds, the flame changed to white smoke and extinguished. There was no splash of oil and the fire could be extinguished safely and reliably.
