Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression devices, in particular to a construction site dust suppression device. Background Art

[0002] Spray dust reduction is a new type of dust reduction technology. Its principle is to use the particles produced by the spray. Because they are extremely small and have basically zero surface tension, they can quickly absorb various sizes of dust particles in the air when sprayed into the air, forming effective dust control. Spray dust reduction requires a dust reduction device.

[0003] The dust suppression device uses high pressure to atomize water into beads equivalent to dust, and blows the water mist into the air through the action of a fan. When the existing dust suppression device is in use, the size of its air outlet is fixed, which makes it inconvenient to adjust the range of water mist emission. At the same time, the device is generally set in places with a lot of dust. After not being used for a period of time, the nozzle on the device is easily clogged by dust and needs to be cleaned manually. However, the number of nozzles is large, and cleaning is very inconvenient. Utility Model Content
