Description

Technical Field

[0001] The embodiments of the present invention relate to the field of dust suppression technology, specifically to a dust suppression device and method for construction engineering. Background Technology

[0002] During the construction of building projects, many processes generate dust pollution to varying degrees. This dust pollution is primarily concentrated in earthwork, including demolition, material handling, excavation, and structural construction. All of these processes produce dust that diffuses into the air. This dust not only affects the surrounding environment, further reducing air quality and impacting the lives of nearby residents, but excessive dust can also easily disrupt the normal operation of various equipment within the construction site. Therefore, specialized dust suppression devices are needed to manage the dust pollution generated during construction.

[0003] In existing technologies, humidification methods are commonly used during construction to reduce the harm of dust problems. This involves using wind-driven sprayers to spray water mist, which is then transported to the dusty area by wind. On the one hand, the wind helps to prevent the spread of dust, and on the other hand, the water mist helps to settle the dust.

[0004] However, during actual construction, dust will spread to the surrounding area. When using a wind-driven sprayer to spray water mist, the spray height and range are relatively small, making it difficult to completely prevent dust from moving out of the construction site. In fact, some dust will move out of the construction site, causing damage to the surrounding environment. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide a dust suppression device and method for construction projects, which solves the technical problem in the prior art that it is difficult to fully prevent dust from moving out of the construction site when simply using a wind-driven sprayer to spray water mist.

[0006] This invention provides a dust suppression device for construction projects, comprising a wind-driven sprayer and a retaining wall, using the retaining wall to enclose the land, and further comprising: A mobile trolley, wherein the air-assisted sprayer is mounted on the top of the mobile trolley, and the mobile trolley is provided with an installation chamber, wherein the installation chamber is provided with an adjustment structure for adjusting the spray angle of the air-assisted sprayer; A water supply tank is installed in the installation chamber and is connected to the air-assisted sprayer. The enclosure wall is equipped with multiple traction and reset structures, each of which is equipped with a corresponding atomizing nozzle. The multiple atomizing nozzles are connected by a pipeline structure, which is connected to the water supply tank. During the movement of the mobile trolley, the pipeline structure and the multiple atomizing nozzles are arranged in an arc shape to reduce dust in the dust-generating area.

A counterweight is provided at the bottom of the traction rope. One side of the traction rope is connected to the atomizing nozzle.

[0011] At least one embodiment of the present invention provides a dust suppression device for construction engineering. The pipeline connection structure includes a connecting pipeline and a water injection interface. The connecting pipeline is horizontally arranged between multiple atomizing nozzles. A connecting valve pipe connects the atomizing nozzles to the connecting pipeline. Multiple water injection interfaces are connected to the connecting pipeline. A connecting interface is provided on the water supply pipe, and the connecting interface is connected to the corresponding water injection interface.

[0012] At least one embodiment of the present invention provides a dust suppression device for construction engineering, which further includes a magnetic card holder, wherein the magnetic card holder is slidably connected to the transverse slide groove, and the atomizing nozzle is magnetically engaged with the magnetic card holder.

[0013] At least one embodiment of the present invention provides a dust suppression device for construction engineering, which further includes a semi-arc meshing clamp. The semi-arc meshing clamp is provided on the connecting bracket through a connecting structure. The semi-arc meshing clamp abuts against the outer wall of the atomizing nozzle and is used to follow the lateral movement of the moving trolley, so that the atomizing nozzle and the connecting pipeline also move laterally.

[0014] At least one embodiment of the present invention provides a dust suppression device for construction engineering, wherein a telescopic plate structure is rotatably mounted on the connecting bracket, and a semi-arc meshing clamp is mounted on the telescopic plate structure.

[0015] A dust suppression method for construction projects includes the following steps: Step 1: Connect the nozzle: Use a semi-circular meshing clamp to abut against the outer wall of the atomizing nozzle; Step 2, Moving the nozzles: Move the mobile trolley towards the dust-generating area. With the help of the connecting pipeline, multiple atomizing nozzles are distributed in an arc shape and moved closer to the dust-generating area. Step 3, Dust Suppression by Spraying: Start the water pump to deliver water from the water tank to the water supply cylinder, and then continue to deliver water from the water supply cylinder into the wind-driven sprayer. The wind-driven sprayer sprays water mist to suppress dust in the dusty area. Through the cooperation of the water supply pipe and connecting pipes, water enters multiple atomizing nozzles under pressure, and finally sprays water mist through multiple atomizing nozzles to suppress dust in the dusty area. Step 4, Nozzle Reset: Move the atomizing nozzle towards the L-shaped trough, the counterweight descends, and the traction rope moves within the curved flow channel, causing part of the atomizing nozzle to re-enter the L-shaped trough.

[0016] The beneficial effects of the embodiments of the present invention are as follows: In this invention, when dust problems occur in certain areas during construction, targeted dust suppression operations can be carried out to prevent dust from spreading to more areas. A mobile trolley can be used to engage with corresponding atomizing nozzles using a semi-circular meshing clamp. As the trolley moves towards the dusty area, multiple atomizing nozzles connected by connecting pipes move closer to the dusty area. Then, a wind-driven sprayer and multiple atomizing nozzles work together to spray water mist, effectively blocking the spread of dust. Furthermore, during normal use, the atomizing nozzles can be installed on a retaining wall to effectively limit the dust's range. Attached Figure Description

[0025] Example 1, as Figures 1 to 6 As shown, the present invention discloses a dust suppression device for construction projects, including a wind-driven sprayer 1 and a retaining wall 2. The retaining wall 2 is used to demarcate the land. Before the construction of the project, in order to plan the construction scope, a retaining wall 2 is set up around the outer edge of the construction project to determine the construction area. Finally, the dust generated during the construction process needs to be confined to the inner area of ​​the retaining wall 2.

[0026] like Figures 1 to 3 and Figure 5 As shown, it also includes a mobile trolley 3, with the air-assisted sprayer 1 mounted on top of the mobile trolley 3. The mobile trolley 3 has an installation chamber 4, and the installation chamber 4 has an adjustment structure for adjusting the spray angle of the air-assisted sprayer 1. The adjustment structure includes a rotating shaft seat 7, a mounting bracket 8, and a drive shaft 9. The rotating shaft seat 7 is rotatably connected to the installation chamber 4, and the mounting bracket 8 is fixedly connected to the top of the rotating shaft seat 7. The drive shaft 9 is rotatably connected inside the mounting bracket 8, and the air-assisted sprayer 1 is mounted on the drive shaft 9. When dust dispersion needs to be addressed, the air-assisted sprayer 1 can be activated. Water mist is sprayed toward the dust dispersion area, using the water mist to drive the dust down. Motor drive devices 26 are installed on both the inner and outer sides of the installation chamber 4. The output ends of the two motor drive devices 26 are connected to the rotating shaft seat 7 and the drive shaft 9, respectively. When the rotating shaft seat 7 is rotated, the installation slot frame 8 and the air-assisted sprayer 1 rotate together along the center point of the rotating shaft seat 7 to adjust the spray direction of the air-assisted sprayer 1. Then, the drive shaft 9 is rotated to adjust the spray angle of the air-assisted sprayer 1 onto the water mist, so as to maximize the working convenience of the air-assisted sprayer 1.

[0027] like Figures 1 to 3 and Figure 5 As shown, the bottom of the mobile trolley 3 is provided with multiple rotating wheels 27. The rotating wheels 27 are set at the bottom of the mobile trolley 3 via telescopic rods 28. The bottom of the mobile trolley 3 is provided with damping springs 29 that cooperate with the extended end of the telescopic rods 28. These damping springs are used to reduce shock during the movement of the mobile trolley 3 and to enable the mobile trolley 3 to adapt to uneven terrain at the construction site during the movement.

[0028] like Figures 1 to 3 and Figure 5 As shown, the water supply tank 5 is installed inside the installation chamber 4. The water supply tank 5 is connected to the air-assisted sprayer 1. A water pump 10 is installed on the outside of the water supply tank 5. A water supply cylinder 11 is installed on the upper side of the water supply tank 5. The input end of the water pump 10 is connected to the bottom of the water supply tank 5, and the output end of the water pump 10 is connected to the water supply cylinder 11. The water supply cylinder 11 is connected to the air-assisted sprayer 1. A water filling interface 31 is connected between the water supply tank 5 and the installation chamber 4. The water pipe of the external water source is connected to the water filling interface 31 to add water into the water supply tank 5. Then, the water pump 10 is used to pump the water out and deliver it to the water supply cylinder 11. Then, the water in the water supply cylinder 11 is delivered to the air-assisted sprayer 1 or multiple atomizing nozzles 6.

[0029] like Figures 1 to 3 and Figure 5As shown, the top two sides of the mobile trolley 3 are fixedly connected to the connecting brackets 12, and the top two sides of the water supply cylinder 11 are provided with water supply pipes 13. The water supply pipes 13 are set on the connecting brackets 12, so that the water supply pipes 13 are longitudinally upward along the side wall of the connecting brackets 12. The water in the water supply cylinder 11 can be arranged upward along the water supply pipes 13, so that the upper side of the water supply pipes 13 is close to the water inlet 21.

[0030] like Figures 1 to 6 As shown, the enclosure wall 2 is equipped with multiple traction and reset structures, each with a corresponding atomizing nozzle 6. The traction and reset structure includes an L-shaped trough 14 and a traction rope 17. The L-shaped trough 14 is suspended from the top of the enclosure wall 2. A curved slide 15 is provided on the L-shaped trough 14, and a transverse slide 16 is provided at the top of the L-shaped trough 14. The traction rope 17 is installed inside the curved slide 15, and a counterweight 18 is installed at the bottom of the traction rope 17. One side of the traction rope 17 is connected to the atomizing nozzle 6. When the atomizing nozzle 6 is pulled to move laterally, the traction rope 17 moves within the curved slide 15, pulling the counterweight 18 upward, so that the atomizing nozzle 6 remains stable during the lateral movement. Then, when the atomizing nozzle 6 is moved towards the L-shaped trough 14, the counterweight 18 descends, causing the traction rope 17 to move within the curved slide, so that part of the atomizing nozzle 6 re-enters the L-shaped trough 14.

[0031] like Figures 1 to 6 As shown, a pipeline connection structure is provided between multiple atomizing nozzles 6. The pipeline connection structure is connected to the water supply tank 5. During the movement of the mobile trolley 3, the pipeline connection structure and multiple atomizing nozzles 6 are arranged in an arc shape to suppress dust in dusty areas. The pipeline connection structure includes a connecting pipeline 19 and a water injection interface 21. The connecting pipeline 19 is arranged horizontally between multiple atomizing nozzles 6. A connecting valve pipe 20 connects the atomizing nozzles 6 and the connecting pipeline 19. Multiple water injection interfaces 21 are connected to the connecting pipeline 19. A connecting interface 22 is provided on the water supply pipe 13. The connecting interface 22 is connected to the corresponding water injection interface 21. When it is necessary to make multiple atomizing nozzles on the corresponding side... When the nozzle 6 sprays water at the dusty area, it connects the upper connecting interface 22 of the water supply pipe 13 to the corresponding water injection interface 21, while keeping the other water injection interfaces 21 closed. Then, the water in the water supply cylinder 11 is transported to the connecting pipe 19 through the water supply pipe 13, and then the water is transported to the corresponding atomizing nozzle 6 through the connecting valve pipe 20. Finally, the atomizing nozzle 6 sprays water mist to perform dust suppression operations on the dusty area. The connecting pipe 19 can keep multiple atomizing nozzles 6 connected. When the connecting pipe 19 is pulled by the moving trolley 3, the connecting pipe 19 drives multiple atomizing nozzles 6 closer to the dusty area.

[0032] like Figures 1 to 6As shown, it also includes a magnetic card holder 23. The magnetic card holder 23 is slidably connected to the transverse slide 16. The atomizing nozzle 6 is magnetically engaged with the magnetic card holder 23. After the atomizing nozzle 6 is transported back into the L-shaped trough 14 after dust removal, in order to ensure that the atomizing nozzle 6 remains stable on the enclosure wall 2 when it is not in use, during the process of the atomizing nozzle 6 moving onto the L-shaped trough 14, one side of the atomizing nozzle 6 is magnetically connected to the magnetic card holder 23 to prevent the atomizing nozzle 6 from falling out of the L-shaped trough 14. Under the action of the counterweight 18, a part of the atomizing nozzle 6 enters the curved slide 15 to protect the atomizing nozzle 6.

[0033] like Figures 1 to 3 and Figure 5 As shown, it also includes a semi-circular meshing clamp 24. The semi-circular meshing clamp 24 is provided on the connecting bracket 12 through a connecting structure. The semi-circular meshing clamp 24 abuts against the outer wall of the atomizing nozzle 6 and is used to follow the lateral movement of the moving trolley 3, so that the atomizing nozzle 6 and the connecting pipe 19 also move laterally. In order to enable multiple atomizing nozzles 6 to follow the moving trolley 3, the semi-circular meshing clamp 24 can be made to mesh with the outer wall of the atomizing nozzle 6 after expansion and deformation. Then, during the movement of the moving trolley 3, the corresponding atomizing nozzle 6 is driven to move in the direction of movement of the moving trolley 3.

[0034] like Figures 1 to 3 and Figure 5 As shown, a telescopic plate structure 25 is rotatably mounted on the connecting bracket 12, and a semi-arc meshing clamp 24 is mounted on the telescopic plate structure 25. The telescopic plate structure 25 is rotatably connected to the connecting bracket 12 via a rotating seat 30. The telescopic plate structure 25 can rotate along the center point of the rotating seat 30, so that the semi-arc meshing clamp 24 can be connected to the corresponding atomizing nozzle 6, and the distance between the semi-arc meshing clamp 24 and the atomizing nozzle 6 can be adjusted by the telescopic plate structure 25.

[0035] The working principle of the dust suppression device used in this construction project: During the construction process, a semi-circular meshing clamp 24 is used to abut against the outer wall of the atomizing nozzle 6, which then drives the mobile trolley 3 to move towards the dust-generating area. Under the action of the connecting pipe 19, multiple atomizing nozzles 6 are driven to be distributed along an arc and close to the dust-generating area. Then, the water pump 10 is started to deliver water from the water supply tank 5 to the water supply cylinder 11. Then, the water in the water supply cylinder 11 continues to enter the wind-driven sprayer 1, which sprays water mist to reduce dust in the dust-generating area. Through the cooperation of the water supply pipe 13 and the connecting pipe 19, the connecting valve pipe 20 is used to control the connection between the connecting pipe 19 and the atomizing nozzle 6, so that water enters multiple atomizing nozzles 6 under pressure. Finally, water mist is sprayed through multiple atomizing nozzles 6 to reduce dust in the dust-generating area.

[0036] After the dust suppression is completed, the atomizing nozzle 6 is moved towards the L-shaped trough 14, causing the counterweight 18 to descend and the traction rope 17 to move within the curved flow channel, so that part of the atomizing nozzle 6 re-enters the L-shaped trough 14.

[0037] Example 2: Based on a dust suppression device for construction engineering, the present invention also proposes a dust suppression method for construction engineering, specifically including the following steps: Step 1, Connect the nozzle: Use the semi-circular engagement clamp 24 to abut against the outer wall of the atomizing nozzle 6; Step 2, Moving the nozzles: Move the mobile trolley 3 towards the dust area. Under the action of the connecting pipe 19, multiple atomizing nozzles 6 are distributed along an arc and close to the dust area. Step 3, Spraying to suppress dust: Start the water pump 10 to deliver water from the water tank 5 to the water supply cylinder 11, and then continue to deliver water from the water supply cylinder 11 to the wind-driven sprayer 1, so that the wind-driven sprayer 1 sprays water mist to suppress dust in the dusty area. In addition, through the cooperation of the water supply pipe 13 and the connecting pipe 19, water enters multiple atomizing nozzles 6 under pressure, and finally sprays water mist through multiple atomizing nozzles 6 to suppress dust in the dusty area. Step 4, Nozzle Reset: Move the atomizing nozzle 6 towards the L-shaped slot frame 14, the counterweight 18 descends, and the traction rope 17 moves in the curved flow channel, so that part of the atomizing nozzle 6 re-enters the L-shaped slot frame 14.
