Description

Technical Field

[0001] The utility model belongs to the technical field of dust suppression devices, in particular to a construction dust suppression device. Background Art

[0002] During the construction process at a construction site, a large amount of dust is usually generated. This dust causes serious pollution to the environment and affects human health. Therefore, dust reduction devices are needed to reduce dust in the air during the construction process at the construction site.

[0003] In the prior art, a dust reduction device usually utilizes a spray mechanism to spray water mist in the air so that the dust is adsorbed in the water mist particles. During the dust reduction process of the dust reduction device, there is still residual dust that cannot be adsorbed by the water mist, resulting in poor dust reduction effect, and part of the water mist forms water droplets that fall to the ground. After a period of time, the water on the ground evaporates and the dust will continue to float in the air. Utility Model Content

[0004] The purpose of the utility model is to provide a construction dust reduction device in response to the above-mentioned technical problems. The dust-containing air is spirally moved in a barrel body through a dust suction pipe. The first spray pipe sprays water mist to absorb the dust and form water droplets that flow along the inner wall of the barrel body into a first dust collecting box, thereby improving the dust removal effect. The residual dust in the barrel body passes through the dust reduction pipe. The second spray pipe sprays water mist. The second dust collecting box collects the water droplets flowing down the dust reduction pipe. The air after dust removal escapes from the dust reduction pipe, thereby further improving the dust reduction effect.

[0030] Embodiment 1:

[0031] This embodiment provides a construction dust reduction device, including:

[0032] The first dust reduction mechanism 1 comprises a barrel body 11, a dust suction pipe 12 tangentially arranged on the outer peripheral wall of the barrel body 11, a fan 13 arranged in the dust suction pipe 12, and a first spray pipe 14 arranged on the outer peripheral wall of the barrel body 11;

[0033] The second dust reduction mechanism 2 comprises a dust reduction pipe 21 and a second spray pipe 22 arranged on the outer peripheral wall of the dust reduction pipe 21;

[0034] The first dust collecting box 3 is located at the bottom of the barrel body 11 and is in communication with the bottom of the barrel body 11;

[0035] The second dust collecting box 4 is located on one side of the first dust collecting box 3. A through hole 6 is opened on the top of the second dust collecting box 4. One end of the dust removal pipe 21 is arranged on the top of the barrel 11, and the other end is located on the top of the through hole 6.

[0036] The water tank 5 is located at one side of the first dust collecting box 3 . The water tank 5 is connected to a water pump 7 . The first spray pipe 14 and the second spray pipe 22 are both connected to the water pump 7 .

[0037] In this technical solution, the first dust reduction mechanism 1 is used for primary dust reduction, and the second dust reduction mechanism 2 is used for secondary dust reduction, which further improves the dust reduction effect. Multiple nozzles can be connected to the first spray pipe 14 and the second spray pipe 22, and the nozzles are connected to the barrel body 11 and the dust reduction pipe 21, wherein the top of the dust reduction pipe 21 is bent and connected to the top of the barrel body 11.

[0038] The barrel body 11 is a cylindrical structure, and the dust suction pipe 12 is tangentially arranged on the outer peripheral wall of the barrel body 11. The fan 13 rotates to generate negative pressure in the dust suction pipe 12, so that dust in the air is sucked into the barrel body 11, and the air containing dust moves in a spiral along the inner wall of the barrel body 11. The first spray pipe 14 sprays water mist, and the water mist absorbs dust in the air. The water mist after absorbing the dust collides with the inner peripheral wall of the barrel body 11 through spiral movement. Some water mist after absorbing the dust gradually gathers to form water droplets and flows downward along the inner peripheral wall of the barrel body 11 to the first dust collecting box 3. The first dust collecting box 3 is used to collect the mixed liquid formed by water after absorbing the dust. The air moves in a spiral in the barrel body 11, which can improve the dust reduction efficiency. The fan 13 can be an existing fan 13.

[0039] During the initial dust reduction process of the first dust reduction mechanism 1, a small amount of dust still remains in the air in the barrel body 11, and the second dust reduction mechanism 2 performs secondary dust reduction at the same time to further improve the dust reduction efficiency. The air after the initial dust reduction in the barrel body 11 enters the dust reduction pipe 21 along the top of the dust reduction pipe 21, and the second spray pipe 22 sprays water mist, which absorbs the dust in the air. The water mist after the dust absorption collides with the inner wall of the dust reduction pipe 21, and some water mist after the dust absorption gradually gathers to form water droplets along the inner wall of the dust reduction pipe 21, passes through the through hole 6 downward and flows into the second dust collection box 4. The air after the secondary dust reduction escapes from the bottom of the dust reduction pipe 21, and the second dust collection box 4 is used to collect the mixed liquid formed by the water after the dust absorption.

[0040] The first spray pipe 14 and the second spray pipe 22 generate water mist by pumping water in the water tank 5 through the water pump 7. The first spray pipe 14 and the second spray pipe 22 can save water resources by spraying water mist, thereby achieving an environmental protection effect.
