Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of operation, transportation, and particularly relates to a convenient spraying dust-settling device for construction site construction which removes dust in the air by using water mist to achieve air purification and environmental protection. BACKGROUND

[0002] In places such as stockyards, mines, quarries, and construction sites, dust is often flying everywhere, seriously polluting the surrounding environment. Under normal circumstances, dust is settled by watering the ground. This method can only adsorb some dust on the ground surface and cannot adsorb dust in the air near the ground, so the efficiency is low and the dust-settling effect is poor. With the improvement of people's environmental awareness and the increasing emphasis on environmental protection, many sites need a dust-settling device that is low in investment, easy to operate, and requires low daily maintenance.

[0003] Chinese patent application No. 201922277585.2 discloses a spraying dust-settling device, which includes a box body, a support, and a cylinder. A water tank is arranged in the box body, the top of the box body is provided with the support, and the top of the support is installed with the cylinder. A high-pressure jet fan is arranged in the cylinder, and an air inlet and an air outlet are formed at both ends of the cylinder. A micro-fine atomizing nozzle is arranged at the air outlet of the cylinder, and a water supply pipe of the micro-fine atomizing nozzle is connected with the water tank. The spraying dust-settling device atomizes water by using the micro-fine atomizing nozzle, and then uses the high wind volume and high wind pressure of the high-pressure jet fan to send the atomized water mist to a long distance, so that the water mist can cover a larger area while reaching a long distance, thereby achieving the effects of dust suppression and dust reduction, reducing the dust concentration value in the air, and improving the air quality.

[0004] The spraying dust-settling device with the above structure has the problems of high cost and loud noise. For large construction projects such as the intersection of Tanghuai Road and Zhengyang Street in the Tanghuai Garden of the Shanxi Transformation and Comprehensive Reform Demonstration Zone, which is not far from the Shanxi Transformation and Comprehensive Reform Demonstration Zone Committee, and the east side of Tanghuai Road and the north side of Zhengyang Street are the main traffic arteries. Due to its location in the city, the project has a high earthwork excavation volume of 250000m³, and the environmental dust-settling pressure is high. To solve the problem of large-scale earthwork excavation and daily environmental dust-settling, a new low-cost, convenient, and easily movable dust-settling device needs to be designed to meet the requirements of on-site mechanical mobility and dust-settling in each construction phase.
