[0002] During municipal engineering construction, such as road construction and pipeline laying, the dust generated can adversely affect the surrounding environment and the health of people. Therefore, dust suppression devices are needed to control dust. These devices are usually placed in the construction area and reduce the content of particulate matter in the air through methods such as water mist dust suppression, creating a relatively clean construction environment.

[0003] Currently, most common dust suppression devices for municipal construction use fans to draw in dust-laden air, which is then filtered by dust-filtering components and combined with water mist to achieve dust suppression. However, with long-term use, the dust-filtering components are prone to clogging due to dust accumulation, leading to poor airflow and a significant decrease in dust suppression efficiency. Furthermore, cleaning the dust-filtering components of existing devices often requires manual operation after shutdown, which is not only labor-intensive but also interrupts dust suppression operations, affecting the continuous dust suppression effect at the construction site and making it difficult to meet the requirements for efficient and stable dust suppression.

[0004] Therefore, a construction dust suppression device for municipal engineering is proposed to address the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a construction dust suppression device for municipal engineering, which aims to improve the problem that the dust filter components in the prior art are prone to clogging due to dust accumulation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

Rotating shafts are rotatably connected to the tops of the two fixed plates 1. An air inlet pipe is fixedly connected to the adjacent side of the two rotating shafts. A spraying assembly for water spraying is fixedly connected to the outer left side of the air inlet pipe. A fixed plate 2 is fixedly connected inside the air inlet pipe.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the structure of a dual-head motor driving the output shaft, rotating plate, and brush to rotate achieves the beneficial effect of preventing filter plate clogging. During operation, the right output end of the dual-head motor drives the output shaft to rotate, causing the rotating plate to synchronously drive the brush to rotate.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1 to 4This utility model provides an embodiment of a construction dust suppression device for municipal engineering, comprising a rotating disk 1 as a supporting foundation for the upper components of the device, providing an installation platform for components such as a fixed plate 2, a rotating shaft 3, and an air inlet pipe 4. Simultaneously, it can rotate as a whole under the drive of a rotating column 16 to adjust the orientation of the air inlet pipe 4 to meet dust suppression requirements in different directions. Fixed plates 2 are fixedly connected to the front and rear sides of the top of the rotating disk 1, providing stable support points for the rotating shaft 3 and ensuring smooth rotation. The stability of the rotating shaft 3 during rotation ensures that the air inlet pipe 4 can be smoothly adjusted in angle. Rotating shafts 3 are rotatably connected to the tops of both fixed plates 2, serving as the connection between the fixed plates 2 and the air inlet pipe 4. This allows the air inlet pipe 4 to rotate around the rotating shafts 3, enabling angle adjustment within a certain range and facilitating changes in the dust suppression direction. The air inlet pipe 4 is fixedly connected to the adjacent side of the two rotating shafts 3 to draw in external dust-laden air and blow out clean air mixed with filtered dust and water mist. Its interior is an airflow channel, and its exterior connects to a spray assembly, providing a mixing space for air and water mist during dust suppression operations. It is the core channel component for achieving the dust suppression function. A spray assembly for water spraying is fixedly connected to the outer left side of the air inlet pipe 4.

[0032] The spraying assembly includes a fixing ring 5 fixed to the left side of the air inlet pipe 4 for mounting atomizing nozzles 6 and a water inlet pipe 7. This ring provides positioning and support, ensuring the atomizing nozzles 6 are stably installed beside the air inlet pipe 4 and guaranteeing accurate water mist spraying. Multiple atomizing nozzles 6 are mounted on the left side of the fixing ring 5, converting the water supplied by the water inlet pipe 7 into atomized water flow that mixes with the air inside the air inlet pipe 4 to create a water mist dust suppression effect. This is a key component for achieving the dust suppression function. The water inlet pipe 7 connects to an external water source and the fixing ring 5, providing water to the atomizing nozzles 6 and ensuring a continuous water supply during dust suppression operations, guaranteeing continuous water mist spraying. The middle of the fixing ring 5 is fixedly connected to the left side of the air inlet pipe 4, and the exterior of the multiple atomizing nozzles 6 is positioned on the left side of the fixing ring 5. The front of the water inlet pipe 7 is positioned on the fixing ring 5. On the rear side, a fixing plate 2 8 is fixedly connected inside the air inlet pipe 4 for installing the dual-head motor 9, providing a stable installation position for the dual-head motor 9, ensuring the stability of the dual-head motor 9 during operation, and thus ensuring the normal functioning of its drive function. The dual-head motor 9 is installed on the top of the fixing plate 2 8, serving as the internal power source of the device, providing rotational power to the output shaft 1 10 and the output shaft 2 14 respectively, driving different components to operate, realizing the functions of cleaning the dust filter plate 13 and accelerating air circulation. The right output end of the dual-head motor 9 is fixedly connected to the output shaft 1 10, which is connected to the right output end of the dual-head motor 9, transmitting the power of the dual-head motor 9 to the rotating plate 1 11, driving the rotating plate 1 11 to rotate, thereby causing the brush 12 to rotate and perform the work of cleaning the dust filter plate 13.

[0033] A rotating plate 11 is fixedly connected to the right side of the output shaft 10. Driven by the output shaft 10, it rotates, causing the brush 12 on the left side to rotate synchronously, providing rotational power to the brush 12. Multiple brushes 12 are located on the left side of the rotating plate 11, contacting the surface of the dust filter plate 13. Through their rotation, they generate friction with the dust filter plate 13, constantly cleaning the dust adsorbed on its surface and preventing clogging. A dust filter plate 13 is installed on the right side of the air inlet pipe 4 to filter the dust-laden air drawn into the pipe, intercepting dust and ensuring clean exhaust air. The key component of air purification is the output shaft 10, which is rotatably connected to the middle of the dust filter plate 13 on the outside right side. The outer sides of multiple brushes 12 are in contact with the outer side of the dust filter plate 13. The output shaft 2 is fixedly connected to the left output end of the dual-head motor 9, which transmits the power of the dual-head motor 9 to the rotating plate 2 15, causing the rotating plate 2 15 to rotate and create airflow disturbance in the air inlet pipe 4. Multiple rotating plates 2 15 are fixedly connected to the outside of the output shaft 2 14 and rotate under the drive of the output shaft 2 14, stirring the air in the air inlet pipe 4 and accelerating the air circulation, so that the dusty air outside can be drawn into the air inlet pipe 4 more quickly.

[0034] Reference Figure 1 and Figure 5 A rotating column 16 is fixedly connected to the bottom of the rotating disk 1, serving as a connection structure between the rotating disk 1 and the transmission components below. This column transmits the rotation of the worm gear 17 to the rotating disk 1, enabling it to rotate and thus adjust the orientation of the air inlet pipe 4. The worm gear 17 is fixedly connected to the outside of the rotating column 16, meshing with the worm 21. Driven by the worm 21, the worm gear 17 rotates, converting its rotational motion into the rotation of the rotating column 16. This is a key transmission component for achieving the rotation of the rotating disk 1. A housing 18 is rotatably connected to the bottom of the rotating column 16 to house and protect the rotating column 16, worm gear 17, worm 21, and other transmission components, providing a mounting surface. The device provides space and protection, while the casters at the bottom facilitate overall movement. The holes at the top ensure that the rotating column 16 can rotate smoothly. The top of the housing 18 has holes, and the top of the rotating column 16 is rotatably connected to the inside of the holes. A mounting plate 19 is fixedly connected to the rear side of the housing 18 for mounting the motor 20, providing a stable mounting base for the motor 20 and ensuring the stability of the motor 20 during operation. The top of the mounting plate 19 is fixedly connected to the motor 20, which serves as a power source for adjusting the dust collection direction, providing rotational power to the worm gear 21, driving the worm gear 21 to rotate, and thus driving the rotating disk 1 and the air inlet pipe 4 to rotate.

[0035] The output end of motor 20 is fixedly connected to worm gear 21, which rotates under the drive of motor 20. Through meshing transmission with worm wheel 17, power is transmitted to worm wheel 17, realizing the rotation of rotating disk 1, thereby adjusting the orientation of air inlet pipe 4. The external rotatable connection of worm gear 21 is to the middle of housing 18. Worm gear 21 and worm wheel 17 are meshed. Universal wheels are provided at the four corners of the bottom of housing 18 to facilitate flexible movement of the device in the construction site, enabling the device to quickly reach the area requiring dust suppression, improving the ease of use and applicability of the device.

[0036] Working principle: When dust suppression is required, the spraying assembly is operated first. The water inlet pipe 7 is connected to an external water source, and water enters the fixed ring 5 through the water inlet pipe 7, and then is sprayed out as atomized water through multiple atomizing nozzles 6, providing a water mist foundation for subsequent dust suppression. At the same time, the dual-head motor 9 inside the air inlet pipe 4 is started. After the dual-head motor 9 starts running, its right output end drives the output shaft 10 to rotate, and the rotating plate 11 on the right side of the output shaft 10 rotates accordingly. The multiple brushes 12 on the left side of the rotating plate 11 rotate synchronously. Since the outside of the brushes 12 is in contact with the dust filter plate 13, the surface of the dust filter plate 13 can be cleaned to prevent dust from clogging the dust filter plate 13 and affecting the dust reduction effect. The left output end of the dual-head motor 9 drives the output shaft 2 14 to rotate, and the multiple rotating plates 2 15 outside the output shaft 2 14 rotate, forming airflow disturbance in the air inlet pipe 4, accelerating air circulation, and drawing the dust-laden air into the air inlet pipe 4. After being filtered by the dust filter plate 13, the clean air mixes with the water mist sprayed from the atomizing nozzle 6 and is blown out from the left side of the air inlet pipe 4 to achieve dust reduction.

[0037] If the dust suppression direction needs to be adjusted, start the motor 20 on the mounting plate 19 on the rear side of the housing 18. The output of the motor 20 drives the worm gear 21 to rotate. Since the worm gear 21 meshes with the worm wheel 17 outside the rotating column 16, the rotation of the worm gear 21 drives the worm wheel 17 and the rotating column 16 to rotate. The rotating disk 1 on the top of the rotating column 16 rotates accordingly, which in turn drives the fixed plate 2 on the top of the rotating disk 1, the rotating shaft 3, the air inlet pipe 4, etc. to rotate as a whole, adjusting the orientation of the air inlet pipe 4 so that the dust suppression range covers different areas of the construction site.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
