Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction equipment for construction sites, in particular to a dust reduction system for construction sites. Background Art

[0002] The construction process involves civil engineering. When the foundation is built in the early stage of construction, a large amount of dust will be generated, and the fine dust particles can easily float in the air. In addition, during the construction process, many building foundation materials are also dusty. Whether in storage or use, they will be moved or windy, causing dust to scatter and float, causing air pollution on the construction site, and even affecting public areas outside the construction site, reducing environmental quality. Therefore, dust removal and reduction measures are very necessary during the construction process.

[0003] Currently, most of the dust reduction measures at construction sites are to arrange atomizing nozzles at equal intervals above the walls. The nozzles are used in large quantities and are unable to reduce dust in the construction area. Existing equipment such as fog cannons can only spray water mist in a straight line in a single direction to reduce dust, with a small effective range and insufficient efficiency.

[0004] In order to solve the above problems, we have made improvements and proposed a dust reduction system for construction sites. Utility Model Content

[0009] As a preferred technical solution of the utility model, a high-power fan is arranged above the ventilation net, and the side surface of the high-power fan is fixedly connected to the inner wall of the arc-shaped air guide duct by bolts. The guide assembly is a cone, and its cone surface is concave inward in an arc shape. The bottom of the guide assembly is the tip of the cone and the bottom surface is circular, and its bottom surface is fixedly connected to the middle part of the top surface of the high-power fan by bolts.
