Description

Be applied to dust environment's anti-blocking fire-extinguishing shower nozzle Technical Field The invention belongs to the technical field of fire extinguishing spray heads, and particularly relates to an anti-blocking fire extinguishing spray head applied to a dust environment. Background Dust environment is ubiquitous in many industrial fields such as coal, grain processing, wood processing, metal polishing, chemical powder production, and the like. Such environments are extremely dangerous in the event of a fire. The traditional fire extinguishing mode, especially when directly adopting high-pressure water to spray or spray water to extinguish fire, high-speed liquid can strongly impact accumulated dust, so that the accumulated dust is easily lifted in a large area, and high-concentration combustible dust cloud is formed. If the dust cloud encounters open fire or high-temperature surface, secondary or even multiple explosions are extremely easy to cause, the destructive power of the dust cloud often exceeds that of the initial fire, and catastrophic casualties and property loss are caused. In the prior art, in order to cope with dust fires, a mode of adding a dust suppressant, an explosion-proof agent or using special foam is generally adopted. However, these methods often rely on separate external agent systems and complex control units, are costly, are complex, and may not respond at sufficient speed in the event of a sudden fire. Furthermore, the dust environment poses a serious challenge for the reliability of the fire extinguishing apparatus itself. Fire extinguishing spray heads, especially precision atomizing spray heads, are extremely easy to invade, adhere and harden by floating dust in the environment in a non-working state, so that the fire extinguishing spray heads are blocked when in emergency, and the fire extinguishing function is completely lost. On the other hand, after a fire is extinguished, the slurry residue formed by mixing the liquid with the dust is difficult to dispose of. These slurries can be hazardous because of the presence of non-fully reacted chemicals, and are very viscous and sedimentary and can easily clog drainage and cleaning equipment, presenting a significant barrier to post-disaster recovery and on-site cleaning. There is currently a lack of an integrated solution that can actively address this problem during fire suppression. Therefore, we provide an anti-blocking fire-extinguishing nozzle applied to dust environment, the device can seal the atomizing nozzle through the ball-type protection cover, prevents the phenomenon that the atomizing nozzle is blocked when using, and simultaneously integrates dust suppression, explosion prevention, high-efficiency fire extinguishment and easy cleaning function after disaster. Disclosure of Invention The invention aims to provide an anti-blocking fire-extinguishing spray head applied to a dust environment, which can seal an atomization spray head through a spherical protective cover, prevent the phenomenon of blocking the atomization spray head when the atomization spray head is used, and integrate functions of dust suppression, explosion prevention, high-efficiency fire extinguishment and easy cleaning after disaster. The technical scheme adopted by the invention is as follows: the anti-blocking fire-extinguishing spray head applied to the dust environment comprises a connecting pipe connected with an external water supply system, wherein a spray head device is arranged at the bottom of the connecting pipe; The spray head device comprises a spherical protective cover communicated with the connecting pipe and two symmetrical L-shaped guide plates fixedly arranged on the inner wall of the connecting pipe, a water guide channel is formed between the two L-shaped guide plates, a hollow rectangular shell is arranged on the outer side of the connecting pipe, a driving assembly is arranged in the hollow rectangular shell, and a worm positioned in the connecting pipe is arranged on the driving assembly; The ball-type protection cover is characterized in that a first through hole is formed in the bottom of the ball-type protection cover, a circular chute is formed in the inner wall of the ball-type protection cover, a worm wheel ring is arranged in the circular chute and meshed with the worm, a ball-type shell body capable of rotating inside the worm wheel ring is arranged on the worm wheel ring, a through groove and two bearing cavities are formed in the ball-type shell body, the through groove is communicated with one another up and down, one of the bearing cavities is internally provided with a dust suppression and explosion prevention agent, the other one of the bearing cavities is internally provided with a polymeric flocculant, the two of the bearing cavities are respectively provided with a second through hole communicated with the through groove, the two second through holes are mutually staggered, and an atomization nozzle
