液として用いることが考慮される。BACKGROUND OF THE INVENTION Conventionally, when cleaning electronic parts, mechanical parts, medical instruments, etc., solvents such as fluorocarbons and trichlorethylene, which do not adversely affect the human body or the environment, are often used as cleaning liquids for the objects to be cleaned. However, these devices do not completely solve the problem of leakage from the cleaning device to the outside. Therefore, it is considered to use alcohols such as isopropyl alcohol, terpene oil, hydrocarbon solvents, and other flammable solvents as cleaning liquids as solvents that do not adversely affect the human body or the environment.

いものであった。。However, these materials are highly flammable and therefore highly dangerous and difficult to use. In particular, these flammable solvent liquids have a high risk of being ignited by sparks, static electricity, etc. generated by external equipment when the solvent gas leaks out of the apparatus. Although some devices have been developed to eliminate this risk, they have complicated mechanisms that make them expensive and difficult to use in practice, and there are no effective extinguishing methods in the event of accidental ignition. It was something that didn't exist. .

可能とする。As described above, in the present invention, a cleaning means filled with a flammable solvent solution is placed in a storage tank containing a non-flammable liquid, and this cleaning means is operated in the storage tank to clean the object to be cleaned. Therefore, if alcohols such as isopropyl alcohol, terpene oil, hydrocarbon solvents, or other flammable solvents are used as cleaning liquids, and solvent gas or flammable solvents leak out from the cleaning means, However, the cleaning means is located in the storage tank, and the leaked flammable solvent gas and flammable solvent liquid come into contact with non-flammable liquid such as water and dissolve, significantly reducing the risk of ignition. Enables safe cleaning.

触して溶解し、引火の危険性が著しく低いものとなり、
高度の安全性を確保できる。If the cleaning means is installed submerged in a nonflammable liquid, alcohols such as isopropyl alcohol, terpene oil, hydrocarbon solvents, and other flammable solvents are used as the cleaning liquid to remove solvent gas and flammable solvents. Even in the event of a leak of flammable solvent liquid, etc. to the outside, 100% of the leaked flammable solvent gas or flammable solvent liquid will come into contact with non-flammable liquid such as water and dissolve, resulting in the risk of ignition. becomes significantly lower,
A high level of safety can be ensured.

る。In addition, if the cleaning tank constituting the cleaning means is installed in a storage tank with a part of the upper end protruding from the nonflammable liquid and located in a non-submerged state, it will be possible to easily take in and take out the items to be cleaned and to connect piping. Even if solvent leaks from parts that come into contact with non-flammable liquids, such as parts, the non-flammable liquids and solvent gas or liquid will not come into contact with each other and pose a risk of ignition, so cleaning is recommended. Work safety can be significantly improved.

業を可能とする。Additionally, in the event that a fire ignites inside the cleaning means, since the cleaning means is located in a nonflammable liquid, the risk of ignition to the outside can be minimized at the initial stage of the ignition. By opening the on-off valve that connects the inside of the cleaning means and the nonflammable liquid in the storage tank, the nonflammable liquid can be introduced into the ignited cleaning means, resulting in extremely quick extinguishing work. is possible.

な廃棄作業が可能となる。In addition, when disposing of flammable solvent liquid such as alcohol that does not have toxicity or other problems, open the on-off valve and introduce non-flammable liquid such as water into the cleaning means to separate the non-flammable liquid and solvent. If the materials are mixed together to ensure that there is no danger of ignition before being disposed of, the disposal process becomes simple.

が可能となる。In addition, when using terpene oils, hydrocarbon solvents, etc., which have a lighter specific gravity than non-flammable liquids such as water and do not dissolve in water, add surfactants to the water so that these flammable solvents can be dissolved. If you mix the agent and make it capable of dissolving the flammable solvent,
The leaked solvent is dissolved in a nonflammable liquid to make it nonflammable, thereby preventing the risk of ignition and making it possible to quickly extinguish the ignited solvent.

ることができ、極めて迅速な消化作業を可能とする。Effects of the Invention Since the present invention is constructed as described above, while a flammable solvent is used as a cleaning liquid, the leaked solvent gas, flammable solvent liquid, etc. come into contact with a non-flammable liquid such as water and are dissolved. In addition to ensuring a high level of safety, in the event that a fire ignites inside the cleaning means, by opening the on-off valve, non-flammable liquid can be introduced into the ignited cleaning means, resulting in extremely quick operation. Enables efficient digestion.

性液体を洗浄手段内に導入し、不燃性液体と可燃性溶剤
液を混合して発火の危険が無い状態としてから廃棄すれ
ば、簡易な廃棄作業が可能となる。In addition, when disposing of flammable solvent liquids such as alcohol that do not have toxicity problems, open the on-off valve and introduce non-flammable liquid such as water into the cleaning means. If the solvent solution is mixed to ensure that there is no danger of ignition before disposal, it becomes possible to easily dispose of the product.

ることが可能となる。Additionally, even in the case of solvents that have a lower specific gravity than nonflammable liquids such as water and do not dissolve in nonflammable liquids, if a surfactant is mixed with the nonflammable liquid to dissolve these solvents, the object to be cleaned can be cleaned. It is possible to dissolve the solvent used in the process, prevent the diffusion of solvent gas, prevent the risk of ignition, and properly extinguish the ignited solvent.
