Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction, in particular to a dust treatment device for construction engineering. Background Art

[0002] Civil engineering activities such as building construction, road construction, and bridge demolition generate large amounts of dust. This dust not only pollutes the environment and affects air quality, but can also pose a health risk to construction workers and nearby residents. Therefore, effectively controlling and reducing dust on construction sites has become a critical issue in environmental protection and occupational health and safety. Traditional dust control methods involve using a spray device to dissolve dust into a water mist that falls to the ground. A spray device typically consists of a high-pressure pump, piping, a nozzle, and a control valve.

[0003] In dust suppression work, traditional spray devices generally adjust the spray flow rate by adjusting the speed of the motor. However, this method cannot ensure constant water pressure, resulting in the spray being sometimes far away and sometimes near, affecting the dust suppression effect. In addition, the spray area adjustment degree is extremely low and cannot adapt to small or large-scale smoke and dust. Utility Model Content

[0030] Example 2:

[0031] See also Figure 1-6, and combined with Example 1, it is further obtained that the spray adjustment mechanism 4 includes a spray flow adjustment component 41 and a spray area adjustment component 42, the spray flow adjustment component 41 includes a limiting housing 411 and a water receiving head 412, the limiting housing 411 is fixedly connected to the lower end of the water pipe 307, the water receiving head 412 is communicated and arranged between the annular water tank 306 and the water pipe 307, the upper end of the water receiving head 412 is rotatably connected to a rotating chassis 413, the rotating chassis 413 is provided with an arc-shaped notch 414, a sliding rod 416 is slidably connected in the arc-shaped notch 414, the upper surface of the sliding rod 416 is fixedly connected to a splicing block 415, the upper surface of the splicing block 415 is fixedly connected to an upper sliding rod 418, a straight sliding groove 417 is provided inside the limiting housing 411, and the upper sliding rod 418 is slidably connected to Inside the straight slide groove 417, a transmission gear 419 is fixedly connected to the outside of the rotating chassis 413. The rotating chassis 413 is rotatably connected to the water receiving head 412, and the limiting sleeve 411 is fixedly connected to the lower end of the water pipe 307. The rotating chassis 413 can be rotated by pulling the handle on the rotating chassis 413. During this process, the inner wall of the arc-shaped notch 414 of the rotating chassis 413 pushes the lower slide bar 416, and the upper slide bar 418 moves synchronously with the splicing block 415. The upper slide bar 418 controls the sliding angle of the splicing block, and the lower slide bar 416 controls the position of the splicing block. The splicing block 415 is assembled into a circle at the center of the rotating chassis 413. The water supply path of the water pipe 307 can be reduced or closed according to the rotation direction of the rotating chassis 413. Then, the center of the rotating chassis 413 can be expanded by pulling the handle in the opposite direction.

[0032] Furthermore, the spray area adjustment assembly 42 includes a threaded sleeve 421, which is rotatably connected to the outside of the support disk 308.

The threaded rod 423 pushes or pulls the fixed block 424 through the pull rod 425 during the sliding process to achieve control. The purpose of controlling the rotation angle of the fan plate 309 is that when the fan plate 309 rotates outward, it is driven by the rotating chassis 413, and the flow in the water pipe 307 is in an increasing state. At this time, the center diameter of the fan plate 309 is also expanding. The fan plate 309 drives the spray head 310 to increase the diffusion area of ​​the spray. After the rotating chassis 413 rotates to reduce the water flow delivered by the water pipe 307, the fan plate 309 will reduce the diameter at the center of the fan plate 309 under the push of the threaded rod 423, reduce the spray area, ensure the spray pressure, and save water resources.

The water flows through the water pipe 307 to the water mist pipe 311, and then forms water mist at the spray head 310. During the dust reduction process, the user can turn the handle on the rotating chassis 413 to increase the water flow rate of the water pipe 307 while expanding the spray area of ​​the spray head 310, thereby increasing the dust reduction efficiency while ensuring the pressure. By reversely controlling the rotation direction of the handle, the spray area can be reduced and water resources can be saved.
