Description

Technical Field

[0002] Water-based fire extinguishers emerged in the 1980s and are based on a physical fire extinguishing mechanism. The agent can form and expand a thin water film on the surface of the combustible, isolating the combustible from the air and extinguishing the fire. Through the atomizing nozzle, a fine water mist is sprayed, spreading over the fire scene and evaporating the heat, rapidly reducing the temperature of the fire scene, while reducing the oxygen concentration in the air in the combustion area to prevent re-ignition. Good anti-reignition performance is an incomparable advantage of water-based fire extinguishers.

However, the current challenge is that the addition of raw materials in the batching process is not automatic and equal. Each time, manual auxiliary addition is required, which is not only inefficient, but also reduces the degree of automation of the production line. Utility Model Content
