Description

Powder type automatic fire extinguisher

The present invention relates to an automatic fire extinguisher, and more particularly, to an automatic fire extinguisher provided to inject a powdered drug, and equipped with an automatic fire extinguisher to be mounted at a specific place to detect heat during a fire and to extinguish the fire at an early stage. The present invention relates to a powder medicine type automatic fire extinguisher capable of automatically spraying a powder medicine.

In general, a fire extinguisher is an apparatus for the initial suppression of a fire, and is classified into various types such as a water fire extinguisher, an acid, an alkali fire extinguisher, a reinforced liquid fire extinguisher, a foam fire extinguisher, and a fire extinguisher according to the extinguishing agent used.

Among them, the fire extinguisher uses specially processed sodium hydrogen carbonate powder (needs fineness of 100 mesh or more), and emits powdered medicine by incombustible high pressure gas such as nitrogen or carbon dioxide.

The spun powdered medicine generates carbon dioxide on the screen to asphyxiate and suffocate, and some of them also have the effect of blocking the radiant heat of the powder, and are suitable for the fire of oil, electricity and chemicals.

The fire extinguisher has a safety pin, a lever, a handle, a lid, a pressurized gas container, a siphon pipe, a hose, a nozzle, and the like. When using the fire extinguisher, the fire extinguisher is first moved from a fire site to a place of 5 [m] to 6 [m]. Next, the safety pin is pulled out and the handle and the lever are gathered together to release the powdered medicine, which is useful for extinguishing the fire.

In this way, fire extinguishers can be stored in the corridors of various buildings, industrial sites, etc. to suppress fires in the early stages of an emergency to prevent further disasters. When a fire occurs in a relatively unattended place, it is often difficult to extinguish it because the state of fire is unknown. In general, it is hardly used for a user to manually extinguish a fire by carrying a fire extinguisher to the site. There are many cases.

In addition, even if you do not know how to use a fire extinguisher, the fire suppression does not occur smoothly.

As is well known, the occurrence of a general fire is usually caused by a cigarette fire that is not completely extinguished or an electric short circuit, and it is often caused by a fire. In the event of a fire, the initial suppression is very important because it can cause not only massive damage to property but also human damage.

In general, as described above, a fire that starts early in the inner space of a garbage collection box or an object storage box has a flame rising upward from the lower side, and if the smoke or flame generated during combustion cannot be identified, the fire occurs. Increasingly, the degree of occurrence of late, the state of late recognition of the fire was more difficult to extinguish the fire due to the use of the fire extinguisher is not good.

The present invention has been made in order to solve the conventional problems as described above, in the automatic fire extinguisher provided to spray the powdered medicine, equipped with an automatic fire extinguisher to be mounted in a specific place to detect the heat during the fire An object of the present invention is to provide a powdered medicine type automatic fire extinguisher that can automatically spray powdered medicine to extinguish a fire.

In the automatic fire extinguisher composed of induction siphon tube,

One end of the heat sensing tube capable of partial rupture by a fire is mounted from the tip of the spinneret, and the other end is sealed as a plug, and the support tube for pressurizing and fixing both ends of the heat sensing tube to maintain the airtightness to the spinneret and the plug. It can be achieved by providing the fastener installed powder medicine type automatic fire extinguisher.

Powdered medicine type automatic fire extinguisher according to the present invention, the thermal sensing tube installed in the automatic fire extinguisher filled with the powdered medicine and nitrogen gas at a predetermined pressure is broken by any part of the fire when the fire occurs as a fire-filled drug filled inside It can be automatically sprayed to prevent fires that initially occur from the inside of installations equipped with garbage collection boxes, object storage boxes, and other internal combustion engines, which can lead to enormous property damage and human injury. It has an effect.
