Description

Technical Field

[0001] The utility model relates to the field of environmental protection equipment, in particular to dust reduction equipment used in environmental engineering. Background Art

[0002] The functions of environmental engineering dust reduction equipment mainly include effectively controlling air quality, protecting human health, and improving production efficiency. They not only help to improve the working environment in industry, mining and other fields, but also have an important impact on protecting the environment and human health. Among them, fog cannon is a common dust reduction equipment. Its working principle is to atomize water through its high-pressure system to form fine water mist particles, which are then sprayed into the air. The water mist particles combine with the dust particles in the air to make the dust quickly settle to the ground. The end of the spray barrel of the fog cannon is generally provided with a protective net to enclose the rotating fan in the spray barrel to prevent foreign matter from entering and affecting the normal use of the fog cannon. The existing protective net generally uses multiple bolts and nuts to fix it at the end of the spray barrel. The vibration of the spray barrel during operation can easily cause the nut to loosen, thereby detaching from the bolt, resulting in failure of the protective net fixation, affecting the protection of the protective net to the spray barrel. In order to solve this problem, a new type of dust reduction equipment for environmental engineering is needed. Utility Model Content
