置に関するもので、特許（粉末薬剤の攪拌手段について
である。Detailed Description of the Invention: Detailed Description of the Invention (Industrial Field of Application) This invention is a fire extinguisher that introduces high-pressure gas into a powder medicine container, stirs the powder medicine with the pressure gas, and releases the medicine. This patent relates to a device (for stirring means for powdered medicine).
（従来の技術）
粉末消火装置は、粉末薬剤を放出する前に、薬剤容器内
に高圧ガスをｇＲき込んで、高圧ガスで粉末薬剤をよく
攪拌してから放出するようになっている。(Prior Art) A powder fire extinguishing system is designed to pump high-pressure gas into a chemical container before discharging a powder chemical, stir the powder chemical well with the high-pressure gas, and then release it.

と、薬剤をノズルより放出した時、正常に放出されない
で、筋す動で放出したり、容器内に薬剤が大量に残る原
因となる。As shown in Fig. 2, the device for injecting high-pressure gas into a drug container includes a gas introduction pipe provided in the drug container a, which branches into a plurality of pipes, and a powder extinguisher at each branch pipe end φj. When the device is installed for a long period of time, the powdered medicine in the container is automatically crushed, and the closer it gets to the bottom of the container, the more it becomes loose. The powder must be introduced into a container and stirred evenly in order to release the drug. If these things are not done perfectly, when the drug is ejected from the nozzle, it may not be ejected normally and may be ejected with a jerking motion, or a large amount of the drug may remain in the container.

果的に行なわれない。As shown in Figure 2, the provision of a large number of gas jets (Ct) is a structure for uniformly stirring the gas, as mentioned above, but it is necessary to install a device that will be installed for a long period of time, or a container that is mounted on a car. In an apparatus in which vertical vibration is applied to the gas, the gas cannot be effectively agitated.

て悪い装置となる。With the above-mentioned structure, such a device sends gas from each injection port GK at the end of the branch pipe from one pressure gas source d, and each injection port C
Although it is intended to inject the pressurized gas in a more forceful manner, it is not necessary to provide a check valve or a gauging net so that each injection port C is injected in a more forceful manner. Moreover, this injection port C
Because the outer periphery of the tube is within the bottom of the drug container, the powder is compacted, pressing tightly against these valves and clogging the mesh of the paddle mesh. Against this resistance, the injection ports C must be opened and the pressurized gas must be injected, but if all the injection ports C do not open all at once, but only one or two parts open. The gas pressure inside the gas introduction pipe 6 suddenly decreases,
Some injection ports do not open, and the injection ports do not release the pressure gas until the end.As a result, the inside of the container is not evenly stirred, resulting in a device with extremely poor radiation performance than the drug nozzle. Become.

The gas pressure of Ad is transmitted to each injection port 2a, 2b, 2o, 2dK without attenuation, and each injection port opens easily to inject high-pressure gas. Once the gas is ejected, even if the gas pressure decreases slightly, the powdered medicine in the container 1 will completely loosen its clumps.
The gas is stirred and distributed uniformly to all parts without any direction.
従って、薬剤は放出管７、放出弁８を経て、ノズルより
正常に放出される。Therefore, the medicine passes through the discharge pipe 7 and the discharge valve 8 and is normally discharged from the nozzle.
