Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering dust reduction, and more specifically, it particularly relates to a dust reduction device. Background Technique

[0002] During the construction process of civil engineering, it is inevitable to generate a large amount of dust. In order to prevent dust from polluting the surrounding environment, it is usually necessary to use a dust reduction device to reduce the dust. Currently, a spray dust reduction device is usually used to reduce the dust. The spray dust reduction device sprays water mist, makes the water mist collide and agglomerate with the dust particles in the air, increases the weight of the dust particles, and finally makes the dust particles settle to the ground under the action of gravity.

[0003] According to a dust reduction device disclosed in the application number: CN202323229873.3, which belongs to the field of building construction, including a trolley. Two cleaning brushes and two installation boxes are alternately installed under the trolley. Three dust suction hoppers are arranged in each of the two installation boxes. A dust filtering box is fixedly installed on one side of the trolley. All six dust suction hoppers are communicated with the dust filtering box. Two suction fans are fixedly installed on one side plate of the dust filtering box. The suction ports of the two suction fans penetrate through the side plate of the dust filtering box; in the utility model, by setting the cleaning brushes and the installation boxes, when the device moves and the suction fans are started, the cleaning brushes will gather the dust on the ground, making the dust located below the installation boxes. When the suction fans work, they will draw air, and the dust located below the installation boxes will be transported into the dust filtering box along the dust suction hoppers and the dust suction pipes. Since the detachable filter screen is located between the dust suction pipes and the suction ports of the suction fans, the dust will fall into the dust filtering box, thus achieving the purpose of cleaning the dust.

[0004] Based on the above, during the use of the existing dust reduction device, it is inevitable for dust to accumulate in the water tank. When the water pump pumps up the dust, it is easy to cause blockage of the atomizing nozzles, affecting the service life of the atomizing nozzles. Summary of the Utility Model

The replacement operation is simple and the work efficiency is improved. The wind direction detection mechanism is set up to detect the wind direction. The wind direction of the construction site can be judged by observing the direction of the wind vane. The wind tube can be adjusted to the same angle as the wind direction. At this time, when dust reduction is carried out, the water mist can cover a wider range and improve the work efficiency. The above-mentioned mechanism is set up to filter the dust and impurities in the water tank, thereby extending the service life and improving the work efficiency. The wind direction detection mechanism can also be used to detect the wind direction and improve the work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
