Description

Technical Field

[0001] This utility model relates to the field of dust suppression device technology, and in particular to a dust suppression device for construction projects. Background Technology

[0002] During construction, most existing construction sites generate a large amount of dust, resulting in high levels of dust and other particulate matter in the air near the construction site. This significantly reduces the environmental quality of the surrounding area. Therefore, in accordance with environmental protection requirements, it is necessary to enclose and suppress dust around the construction site. Most existing dust suppression methods are spray dust suppression, which involves installing atomizing nozzles at the enclosure, pressurizing water and supplying it to the atomizing nozzles through water supply pipes, and then spraying it out to continuously suppress dust near the enclosure, thereby reducing the impact on the environmental quality of the surrounding area of ​​the construction site.

[0003] However, this dust suppression method has the drawback of having a small dust suppression area and poor dust suppression effect because the water supply pipe is fixedly installed along the distribution direction of the enclosure. Therefore, the distance at which the atomizing nozzles on the water supply pipe spray water is fixed, and the area that can be dusted is also fixed and limited. Therefore, this utility model proposes a dust suppression device for construction projects to solve the above problems. Utility Model Content

[0022] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a dust suppression device for construction projects, including a support frame 1, a housing 2, a connecting pipe 3, an annular pipe 4, and atomizing nozzles 5. The housing 2 is located at the top of the support frame 1. A swing mechanism is located inside the housing 2, and a lifting mechanism is located at the top of the swing mechanism. The connecting pipe 3 is fixedly connected to the top of the lifting mechanism. Multiple annular pipes 4 are located on the outer side of the connecting pipe 3, and multiple atomizing nozzles 5 are equidistantly distributed in a ring on the outer side of the annular pipes 4. A water conveying mechanism is located at the top of the housing 2, through which water is conveyed into the interior of the connecting pipe 3. Pipe 3 then delivers water into the interior of the annular pipe 4. The annular pipe 4 sprays the water to the outside through the atomizing nozzle 5. The atomized water can adsorb dust floating in the air, forming larger agglomerates. These agglomerates are more likely to settle to the ground due to gravity, thus achieving separation from the air and playing a role in dust suppression. The lifting mechanism can drive the connecting pipe 3 to move up and down to adjust the connecting pipe 3 to a suitable height. The swing mechanism can drive the connecting pipe 3 to swing back and forth. The connecting pipe 3 can drive the annular pipe 4 and the atomizing nozzle 5 to swing back and forth, thereby increasing the spray range of the atomizing nozzle 5 and improving the dust suppression effect.

[0023] The swing mechanism includes a rotating shaft 6, a rotating arm 7, a connecting rod 8, a slotted groove 9, and a protruding rod 10. The rotating shaft 6 is hinged to the left side of the support frame 1, and the rotating arm 7 is hinged to the right side of the support frame 1. The bottom end of the rotating shaft 6 is fixedly connected to the connecting rod 8, which has a slotted groove 9 inside. The bottom end of the rotating arm 7 is fixedly connected to the protruding rod 10, and the top end of the protruding rod 10 passes through the slotted groove 9. A self-locking motor 18 is fixedly installed on one side of the bottom of the support frame 1. The output end of the self-locking motor 18 is fixedly connected to the bottom of one end of the rotating arm 7, and the self-locking motor 18 can drive the rotation. The arm 7 rotates on top of the support frame 1. The protruding rod 10 at one end of the rotating arm 7 is inserted into the strip groove 9 inside the connecting rod 8. The connecting rod 8 is connected to the rotating shaft 6 as a whole. While the rotating arm 7 is making circular motion, it can drive the connecting rod 8 to drive the rotating shaft 6 to swing back and forth. The protruding rod 10 can slide along the inner wall of the strip groove 9 to avoid interference between the connecting rod 8 and the rotating arm 7. The rotating shaft 6 is connected to the connecting pipe 3 as a whole through the vertical rod 11 and the threaded rod 12. It can drive the connecting pipe 3 to swing back and forth. The connecting pipe 3 drives the atomizing nozzle 5 to swing back and forth through the annular pipe 4 to increase the spray range of the atomizing nozzle 5 and improve the dust suppression effect.

[0024] The water conveying mechanism includes a water pump 16 and a telescopic pipe 17. The water pump 16 is fixedly installed on the top of the housing 2.

One end of the connecting valve is connected to an external water source through a water pipe. The water pump 16 and the telescopic pipe 17 work together to automatically deliver water into the interior of the connecting pipe 3. The telescopic pipe 17 can automatically extend and retract with the lifting and lowering movement of the connecting pipe 3 to avoid interfering with the lifting and lowering movement of the connecting pipe 3. The connecting pipe 3 delivers water into the interior of the annular pipe 4. The annular pipe 4 sprays water to the outside through atomizing nozzles 5. The atomized water can adsorb dust floating in the air and form larger agglomerates. These agglomerates are more likely to settle to the ground under the action of gravity, thereby achieving separation from the air and playing a role in dust suppression.

[0025] The lifting mechanism includes a vertical rod 11, a threaded rod 12, a knob 13, a groove 14, and a slider 15. The top end of the rotating shaft 6 is fixedly connected to the vertical rod 11, and the top end of the vertical rod 11 is rotatably connected to the knob 13.

The protruding rod 10 at one end of the rotating arm 7 is inserted into the strip groove 9 inside the connecting rod 8, and the connecting rod 8 is connected to the rotating shaft 6 as a whole. While the rotating arm 7 is making circular motion, it can drive the connecting rod 8 to drive the rotating shaft 6 to swing back and forth.
