Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust reduction devices, in particular to a dust reduction device for construction projects. Background Technique
[0002] With the acceleration of the urbanization process and the increase in construction activities, the dust pollution generated in construction projects has increasingly become an important issue for the environment and public health. Dust not only affects air quality but may also cause respiratory diseases, reduced visibility, and damage to the ecosystem. Especially under dry and windy conditions, the dust problem generated at the construction site is more serious, so effective control measures are needed to reduce its impact on the surrounding environment.
[0003] Currently, the method of spraying water to reduce dust is generally adopted to reduce dust pollution. Existing construction projects usually use dust reducers to spray water on the construction site to achieve the purpose of dust reduction. These dust reducers operate according to the air delivery principle. First, a high-pressure pump and a micro-atomizing nozzle are used to atomize water, and then the air volume and air pressure of the fan are used to send the atomized water mist to a farther distance, so that the water mist can cover a larger area. After the water mist condenses with the dust in the air, it falls, thus achieving the purpose of dust reduction.
[0004] However, the range of the water mist sprayed by the dust reducers in the prior art is generally fixed and non-adjustable. If it is desired to reduce the dust in the distance, the entire device must be moved to the dust reduction location to complete the adjustment. In some construction sites, due to the relatively complex terrain, it is not convenient to move the dust reducer as a whole, resulting in the dust reducer being unable to reduce the dust in the distance, and the dust reduction range is limited. Content of the Utility Model
[0005] The purpose of the utility model is to provide a dust reduction device for construction projects that can adjust the range of the water mist in order to solve the above problems.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A dust reduction device for construction projects includes a moving frame, a mounting plate, an adjusting component, an air duct, a fan, an annular magnet, an iron nozzle, and a spraying component. The top of the moving frame is rotatably connected with the mounting plate. The top of the mounting plate is provided with the adjusting component. The adjusting component is used to adjust the up and down orientation of the air duct. A fan is installed in the air duct. An annular magnet is connected to the air outlet of the air duct. An iron nozzle is magnetically attracted to the annular magnet. The iron nozzle is flat, and the side close to the annular magnet is larger than the side far from the annular magnet. A spraying component is arranged in the air duct, and the spraying component is used to atomize and spray water.
[0007] Preferably, the adjusting assembly includes a mounting frame, a motor, a swing plate and a rotating shaft. The top of the mounting plate is connected with the mounting frame. The rotating shaft is rotatably connected to the mounting frame. The swing plate is connected to the rotating shaft. The air duct is installed on the side of the swing plate. The motor is installed on the top of the mounting plate, and the output shaft of the motor is connected to the rotating shaft.
[0008] Preferably, the spraying assembly includes a water pump, a liquid suction pipe, a liquid delivery pipe and an atomizing nozzle. The atomizing nozzle is installed on the side of the fan housing and is directly opposite to the spray outlet of the flat iron nozzle. The water pump is installed on the mounting plate. The liquid suction pipe and the liquid delivery pipe are connected to the water pump, and the liquid delivery pipe is communicated with the atomizing nozzle.
[0009] Preferably, it further includes a water storage cylinder, a honeycomb activated carbon plate and a water injection pipe. The bottom inside the moving frame is connected with the water storage cylinder. The liquid inlet end of the liquid suction pipe extends into the water storage cylinder. The honeycomb activated carbon plate for filtering impurities is connected to the upper part inside the water storage cylinder.

[0011] Preferably, it further includes a hand push rod. The side of the moving frame is connected with the hand push rod, and the hand push rod is connected with a rubber sleeve.
[0012] The beneficial effects of the utility model are as follows:
[0013] 1. The flat iron nozzle magnetically attracted to the annular magnet helps to make the sprayed water mist more concentrated, enabling the water mist to be sprayed upward in a concentrated manner, increasing the spraying distance of the water mist, making the water mist spray farther, expanding the dust suppression range. Removing the flat iron nozzle from the annular magnet allows the water mist to be directly blown out from the air outlet of the air duct, making the water mist spray outward in a dispersed manner, reducing the spraying distance of the water mist, and making the water mist disperse within a closer range to enhance the dust suppression effect in a local area, achieving the effect of being able to adjust the water mist range, and the operation of adjusting the water mist range is simple, convenient and fast.
[0014] 2. By arranging the honeycomb activated carbon plate in the water storage cylinder, impurities in the water can be adsorbed and filtered to prevent impurities from entering the atomizing nozzle, thereby avoiding blockage of the atomizing nozzle, ensuring the normal operation of the water mist spraying and dust suppression work, and improving the dust suppression efficiency.

Specific embodiments
[0020] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0021] A dust reduction device for construction projects, see Figures 1-4, including a moving frame 1, a hand push rod 2, a mounting plate 3, an adjusting component, an air duct 8, a fan 81, a ring magnet 9, an iron nozzle 10, a spraying component and a support block 18. Wheels are installed at the four corners of the bottom of the moving frame 1 to facilitate the movement of this dust reduction device. A hand push rod 2 is connected to the left side of the moving frame 1, and through the hand push rod 2, it is convenient to push this dust reduction device to move. A rubber sleeve is connected to the hand push rod 2 to increase the friction with the hand and prevent slipping. The top of the moving frame 1 is rotatably connected to a mounting plate 3. An adjusting component is provided on the top of the mounting plate 3. The adjusting component includes a mounting frame 4, a motor 5, a swing plate 6 and a rotating shaft 7. A mounting frame 4 is connected to the left side of the top of the mounting plate 3. A rotating shaft 7 is rotatably connected to the mounting frame 4. A swing plate 6 is connected to the rotating shaft 7. The shape of the swing plate 6 is U-shaped. A motor 5 is installed on the front side of the top of the mounting plate 3. The output shaft of the motor 5 is connected to the rotating shaft 7. An air duct 8 is connected to the right side surface of the U-shaped swing plate 6. A fan 81 is installed in the air duct 8. A ring magnet 9 is connected to the air outlet of the air duct 8. An iron nozzle 10 is magnetically attracted to the ring magnet 9. The iron nozzle 10 is flat, and the side close to the ring magnet 9 is larger than the side far from the ring magnet 9, which is beneficial to improving the hydrodynamic performance of the air flowing through the iron nozzle 10 and helps to make the sprayed water mist more concentrated, so as to spray the water mist farther. A spraying component is provided in the air duct 8. The spraying component includes a water pump 11, a liquid suction pipe 12, a liquid delivery pipe 13 and an atomizing nozzle 14. An atomizing nozzle 14 is installed on the right side surface of the outer shell of the fan 81. The atomizing nozzle 14 is directly opposite to the spray outlet of the iron nozzle 10. A water pump 11 is installed on the right side of the mounting plate 3. The input end of the water pump 11 is connected to a liquid suction pipe 12. The output end of the water pump 11 is connected to a liquid delivery pipe 13. Both the liquid suction pipe 12 and the liquid delivery pipe 13 are flexible hoses. The liquid delivery pipe 13 extends into the ring magnet 9 and is communicated with the atomizing nozzle 14. A support block 18 is connected to the right side of the top of the mounting plate 3. The support block 18 is located on the left side of the water pump 11 and under the air duct 8 to support the air duct 8 and enhance the stability of the air duct 8 when it is in a horizontal state.
[0022] Connect the liquid extraction pipe 12 to an external pipeline. When the water pump 11 operates, it can pressurize water and transport it through the liquid delivery pipe 13 to the atomizing nozzle 14. Through the atomizing nozzle 14, the water can be atomized and sprayed out. The fan 81 operates to generate wind force and wind pressure to blow the atomized water mist outward through the iron nozzle 10. Since the iron nozzle 10 is flat and the side closer to the annular magnet 9 is larger than the side farther from the annular magnet 9, it is beneficial to improve the hydrodynamic performance of the air flowing through the iron nozzle 10, which helps to make the sprayed water mist more concentrated, enabling the water mist to be concentrated and sprayed into the air, increasing the spraying distance of the water mist, making the water mist spray farther, reducing the diffusion of the water mist in the air. A farther spraying distance means that the water mist can be dispersed in a larger area, covering a wider area, increasing the dust suppression range, thereby helping to more effectively capture and settle the dust particles in the air and enhancing the dust suppression effect. Controlling the operation of the motor 5 can drive the rotating shaft 7 to drive the swing plate 6 to swing up and down, so that the air cylinder 8 can drive the components thereon to swing up and down to meet the spraying requirements at different heights. When it is necessary to make the water mist disperse and spray into the air, reduce the spraying distance of the water mist, and enhance the dust suppression effect in a local area, the iron nozzle 10 can be removed from the annular magnet 9. Then the water mist is directly blown out from the air outlet of the air cylinder 8, causing the water mist to disperse and spray into the air, reducing the spraying distance of the water mist, and making the water mist disperse within a closer distance to enhance the dust suppression effect in the local area, especially in the case where it is necessary to quickly reduce the dust concentration near the construction site. In this way, the flat iron nozzle 10 magnetically adsorbed on the annular magnet 9 of this device helps to make the sprayed water mist more concentrated, enabling the water mist to be concentrated and sprayed into the air, increasing the spraying distance of the water mist, making the water mist spray farther, increasing the dust suppression range. Removing the flat iron nozzle 10 from the annular magnet 9 can make the water mist directly blown out from the air outlet of the air cylinder 8, causing the water mist to disperse and spray into the air, reducing the spraying distance of the water mist, and making the water mist disperse within a closer distance to enhance the dust suppression effect in the local area, achieving the effect of being able to adjust the water mist range, and the operation of adjusting the water mist range is simple, convenient, and fast.
[0023] See Figures 1-3 , it further includes a water storage cylinder 15, a honeycomb activated carbon plate 16, and a water injection pipe 17. The inner bottom of the moving frame 1 is connected with a water storage cylinder 15. The liquid inlet end of the liquid extraction pipe 12 extends into the water storage cylinder 15. The upper part inside the water storage cylinder 15 is connected with a honeycomb activated carbon plate 16 for filtering impurities. The honeycomb activated carbon plate 16 is located below the liquid extraction pipe 12. The lower part at the rear side of the water storage cylinder 15 is communicated with a water injection pipe 17.
[0024] Connect the water injection pipe 17 to an external pipeline to inject water into the water storage cylinder 15. The honeycomb activated carbon plate 16 can adsorb and filter impurities in the water to prevent impurities from entering the atomizing nozzle 14 through the liquid extraction pipe 12, the water pump 11, and the liquid delivery pipe 13, thereby avoiding clogging of the atomizing nozzle 14 and ensuring the normal operation of the water mist dust suppression work and improving the dust suppression efficiency. The water storage cylinder 15 is a water storage cylinder 15 with a detachable cylinder cover. By removing the cylinder cover from the water storage cylinder 15, the honeycomb activated carbon plate 16 can be replaced or cleaned to ensure the filtering performance of the honeycomb activated carbon plate 16. The water storage cylinder 15 with a detachable cylinder cover is a prior art and will not be elaborated here.
