Description

Technical Field

[0001] The invention relates to the technical field of road dust removal, and more specifically to a construction dust removal device. Background Art

[0002] Construction refers to production activities during the implementation phase of engineering construction, and is the construction process of various buildings. Construction mainly involves the hazards of toxic gases such as cement dust, welding manganese dust, and paint. With the reform of technology, some dust and toxic hazards have been eliminated. For example, after the implementation of concrete, cement pollution is being eliminated. Other dust and toxicity should be controlled by measures. Construction units should provide workers with safety protection equipment and safety protection clothing, and inform them in writing of the operating procedures of dangerous positions and the hazards of illegal operations. Workers should abide by the mandatory standards, rules and regulations and operating procedures for safe construction.

[0003] During the construction process at the construction site, various dump trucks are rampant, and the dust is relatively large, which causes serious damage to the environment. The sand and stone screening or cement mixing process at the construction site or off-site will also cause a lot of dust. The existing dust removal devices generally sprinkle water over a large area to achieve the effect of dust reduction, but it will cause a large amount of sewage to flow, affecting the ground conditions, and the effect is not good and cannot be maintained for a long time.

[0004] Existing patent 1: The Chinese patent with the authorization publication number CN219815701U discloses a construction site dust removal device. By starting the device and using a booster rod to control the device to complete the dust removal work, after starting the device, fine dust will be sucked into the dust bag inside the dust removal box from the dust removal port, and the nozzle will spray relatively fine water. Personnel can open the door of the dust removal box to replace or clean the dust bag according to needs, and personnel can fill water into the water tank through the water filling port;

[0005] Relevant staff engaged in construction work have found that directly spraying water to remove dust at the construction site will cause a large waste of water resources. At the same time, a large amount of water droplets that absorb dust will be spilled on the ground, which will affect the construction. The ash on the ground will dry up and the dust will easily be raised again, causing more serious dust pollution.

[0006] Existing patent 2: The Chinese patent with the authorization publication number CN219744342U discloses a construction site dust removal device, which supports and fixes the high-speed air duct through a hollow chassis and a hollow vertical pipe. The high-speed air blowing mechanism in the high-speed air duct outputs a high-speed airflow upward, and the high-speed air blowing mechanism disperses the water flow input by the atomizing water inlet pipe to form a water mist, which is sprayed out from the upper end of the high-speed air duct. The dust in the air is adsorbed by the water mist sprayed from the upper end of the high-speed air duct and falls under the action of gravity. The high-speed airflow passes through the inner cavity of the hollow chassis and the suction seat to inlet air, so that the upper end of the suction seat generates a negative pressure, and the falling dust-containing water mist is sucked in through the filter felt pad. After the dust-containing water mist passes through the filter felt pad, the water droplets and dust are filtered by the filter felt pad;

[0007] Although this construction site dust removal device can prevent dust from being raised again after the ground moisture has dried, thereby improving the dust removal efficiency, it is not very effective in reducing road dust during actual use, especially when protecting the water-stable layer during road construction. The traditional method uses a sprinkler truck to spray and reduce dust, and the road dust still exists after drying, which only treats the symptoms but not the root cause. Secondly, the trees on the green belts on both sides of the road are also covered with dust. If they are not washed and settled, they will drift to the road surface after the wind blows, increasing the road dust and affecting the construction environment. Summary of the invention
