Description

Technical Field

[0001] The present application belongs to the technical field of building construction, and in particular relates to a construction dust reduction device. Background Art

[0002] With the continuous acceleration of urban modernization, a large number of construction sites have inevitably appeared in the city. Various construction sites have caused very adverse effects on the surrounding environment. The first to be affected is dust pollution. This type of dust has small particle size, high dispersion, large relative surface area, strong respirability, and wide diffusion surface, which increases the harm to the human body. In addition, gas adsorption reduces the wetting and condensation properties of dust. In addition, under the influence of wind flow and various agitations in the working environment, it will float in the air for a long time and drift everywhere, which will also cover the construction site with a thick layer of dust. Moreover, there are a large number of substances harmful to the human body in these dusts, which will affect the health of the workers. Now most of the shock absorption sites use spraying to reduce the dust content in the air.

[0003] The existing Chinese patent with publication number CN110180289B discloses a dust removal device for construction, including an air duct, an air supply duct, a box, a first servo motor and a rotating frame, the two sides of the box are equipped with walking wheels through bearings, one side of the walking wheel is fixedly equipped with a universal wheel, the side of the box is provided with four groups of water level observation holes, one side of the water level observation holes is fixedly equipped with two groups of solar panels, a water tank is provided inside the box, one side of the water tank is connected to a water pump through a water inlet, a first servo motor is installed on the inner side of the frame, an air duct is installed on the top of the frame through a knob, an air supply duct is installed on one side of the air duct, and a spray device is fixedly installed inside the air supply duct.

[0004] Although the above-mentioned dust removal device increases the spray range, its spray efficiency is lower as the spray range increases, and improvements are made to this end. Utility Model Content

[0005] The purpose of this application is to provide a construction dust reduction device to address the above-mentioned technical problems, improve spray efficiency and ensure spray uniformity.

[0006] The present application provides a construction dust reduction device, comprising:

[0007] A jet tube, including an air inlet and an air outlet;

[0008] The fan is installed at the air inlet end of the ejector tube.

By making the angle of the spray range of the nozzle on the first delivery pipe larger than the angle of the spray range of the nozzle on the second delivery pipe, it is ensured that the atomization effect is maintained while increasing the spray efficiency. The nozzle is evenly installed on the first delivery pipe and the second delivery pipe. After the installation is completed, the angle is adjusted according to the installation position through the ball joint structure to improve the convenience of adjustment.

[0014] Furthermore, the nozzle comprises:
