Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction equipment, in particular to a pitching device driven by a servo motor for a fog cannon. Background Technique

[0002] The traditional dust removal method in steel mills is to choose water spraying for dust removal. However, the water droplet particles are too large and the dust particle size is too small, and most of them cannot adhere, resulting in a weak dust removal effect. To solve the above problems, the Eagle Eye fog cannon came into being. Through high-precision development and production, the Eagle Eye monitoring system monitors every place in the space. When it captures a large amount of dust rising in the monitored area, it will feed back the information to the central control system, and then the central control system controls the fog cannon to spray. The fog cannon uses a high-pressure pump to pressurize water, and then atomizes the water through a micro-fine nozzle in the pipeline. Through the air volume and air pressure of the fan, the water mist is sprayed to a relatively long distance. The water mist particles generated by spraying can quickly adsorb the dust in the air and accelerate the dust settlement, thereby achieving the effect of solidifying dust.

[0003] The intelligent control system of the Eagle Eye fog cannon plays an important role in steel enterprises. It is not only a simple dust suppression means, but also a barrier to protect the healthy working environment of workers. Now more and more enterprises are facing ultra-low emission transformation, and the Eagle Eye fog cannon is a key link. In practical applications, the Eagle Eye fog cannon has the following characteristics: strong wind force, high and far range, good penetration, wide coverage, and fast spraying speed. When spraying dust removal on the yard prone to dust generation, the sprayed fog particles are smaller. When contacting the dust, they are easy to adsorb the dust particles and quickly suppress and settle the dust.

[0004] When the Eagle Eye fog cannon captures the dust suppression position of the vehicle, an accurate transmission mechanism is required to align the muzzle of the Eagle Eye fog cannon with the dust generation point to achieve the effect of accurate dust suppression and energy conservation and emission reduction. Ordinary fog cannons cannot achieve precise control and do not meet the requirements of ultra-low emission transformation.

[0005] Therefore, it is necessary to provide a pitching device driven by a servo motor for a fog cannon to solve the above problems. Summary of the Utility Model
