Description

Technical Field

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

[0002] Spray dust removal refers to the method and technology of suppressing and capturing dust by dispersing water into droplets and spraying them at the dust source. Spray dust removal is a new type of dust removal technology. Its principle is to use the particles generated by the spray. Because of its extremely small size and basically zero surface tension, it can quickly absorb various dust particles of different sizes in the air when sprayed into the air, forming effective dust removal, which has a good effect on dust control and removal in large open areas. It is inevitable that a large amount of dust will be generated during construction on construction sites, so this requires a dust removal device for construction sites. Some of the existing dust removal devices use an external water pump to make the water spray head spray water, and the water sprayed by the fan is diffused through the high-speed wind body to remove dust from the construction site. Due to the lack of lifting function, the height of the dust removal mechanism cannot be adjusted according to the height of the spray dust removal, which greatly reduces its applicability. There are also some dust removal devices that can be lifted and lowered, but the angle adjustment of the dust removal mechanism can only be adjusted to a smaller degree, and cannot be adjusted and rotated to a large degree, and an additional self-locking unit is required, which limits the dust removal range of the dust removal mechanism.
