Description

Technical Field

[0001] This utility model relates to the field of construction technology, and more specifically, to a dust suppression device. Background Technology

[0002] A large amount of dust is generated during the construction of civil engineering projects, so dust suppression devices are needed to control the dust generated at the construction site.

[0003] Existing technologies commonly employ spray dust suppression devices, such as using a high-pressure water pump to deliver water to atomizing nozzles to form a water mist (as described in patent CN221230219U), or using a wind-driven sprayer to atomize water and combine it with dust particles for settling (complying to Article 5.5.10 of the "Standard for Construction Dust Control at Construction Sites"). However, such devices have significant drawbacks: 1. Water pipe blockage is a prominent problem: Dust, silt and other impurities in the construction environment can easily enter the water supply pipeline, leading to the accumulation of impurities inside the pipe (such as packing material falling off, silt deposition, etc.), which manifests as a decrease in water supply pressure, insufficient air volume and increased pressure drop.

[0004] Clogging directly leads to a reduction in water spray force and a decrease in atomization effect (such as insufficient water pressure at the nozzle), affecting the contact efficiency between water mist and dust (dust suppression mechanisms such as Brownian motion and interception effect fail).

[0005] 2. Existing cleanup methods are passive and inefficient: Routine maintenance relies on manual removal of impurities from the pipes periodically (such as disassembling and flushing the pipes), but the complex construction environment leads to insufficient cleaning frequency, making it impossible to ensure unobstructed pipe flow in real time.

[0006] Some of the improved designs only target the cleaning of impurities inside the water tank (such as the water tank cleaning device in the aforementioned patent), but do not solve the problem of blockage in the middle section of the water supply pipeline and at the nozzle connection.

[0007] In summary, while existing technologies can achieve basic dust reduction, they lack a built-in real-time pipe cleaning mechanism, making it difficult to maintain stable dust reduction efficiency in construction environments with high dust concentrations. Utility Model Content

[0008] Therefore, in order to solve the problem that existing dust suppression equipment lacks a built-in real-time pipe cleaning mechanism, making it difficult to maintain stable dust reduction efficiency in construction environments with high dust concentrations, this utility model provides a dust suppression device, the specific technical solution of which is as follows: A dust suppression device, comprising: A ventilation duct, on which a water pipe, a dust suppression structure, and a dust suction structure are installed; the dust suppression structure has an atomizing structure and an air supply structure for spraying water mist out of the ventilation duct; the dust suction structure has a filtering structure and a negative pressure structure for sucking dust into the ventilation duct; the water pipe is connected to the atomizing structure; A cleaning device is installed inside the water pipe and is used to clean impurities and dirt adhering to the inside of the water pipe. A rotating device is provided, wherein the air duct is mounted on the rotating device, and the rotating device is used to drive the air duct to rotate. A moving device, wherein the rotating device is disposed on the moving device, and the moving device is used to drive the rotating device to move.

[0009] The aforementioned dust suppression equipment integrates a cleaning device within the water pipes to remove adhering impurities in real time, preventing increased pipeline pressure drop. Traditional maintenance relies on manual disassembly and flushing, while this solution automates cleaning, significantly reducing downtime. A rotating device drives the air duct to rotate, causing the atomizing structure to spray water mist to form a ring-shaped coverage area, overcoming the blind spots of fixed nozzles. Position adjustment adapts to different dust sources (such as material discharge ports and conveyor belts), achieving a three-in-one dust suppression system of "movement-rotation-spraying." This dust suppression equipment solves the problem of existing dust suppression equipment lacking a built-in real-time pipeline cleaning mechanism, making it difficult to maintain stable dust reduction efficiency in high-dust-concentration construction environments.

[0025] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0026] like Figures 1-3As shown, a dust suppression device in one embodiment of this utility model includes a duct 1, a cleaning device 2, a rotating device 3, and a moving device 4. The duct 1 is equipped with a water pipe, a dust suppression structure, and a dust collection structure. The dust suppression structure has an atomizing structure and an air supply structure for spraying water mist out of the duct 1. The dust collection structure has a filtering structure and a negative pressure structure for drawing dust into the duct 1. The water pipe is connected to the atomizing structure. The cleaning device 2 is located inside the water pipe and is used to clean impurities and dirt adhering to the water pipe. The duct 1 is mounted on the rotating device 3, which drives the duct 1 to rotate. The rotating device 3 is mounted on the moving device 4, which moves the rotating device 4.

[0027] The aforementioned dust suppression equipment integrates a cleaning device 2 within the water pipe to remove attached impurities in real time, preventing increased pressure drop in the pipeline. Traditional maintenance relies on manual disassembly and flushing, while this solution automates cleaning, significantly reducing downtime for maintenance. A rotating device 3 drives the air duct 1 to rotate, causing the atomizing structure to spray water mist to form a ring-shaped coverage area, overcoming the blind spot problem of fixed nozzles. Position adjustment adapts to different dust sources (such as material discharge ports and conveyor belts), achieving a three-in-one dust suppression system of "movement-rotation-spraying." This dust suppression equipment solves the problem that existing dust suppression equipment, lacking a built-in real-time pipeline cleaning mechanism, struggles to maintain stable dust reduction efficiency in high-dust-concentration construction environments.

[0028] like Figures 2-3As shown, in one embodiment, the cleaning device 2 includes a support 21, a first moving mechanism 22, a second moving mechanism 23, and a cleaning mechanism 24; the first moving mechanism 22 and the second moving mechanism 23 are both mounted on the support 21, and the cleaning mechanism 24 is located in front of the support 21; the first moving mechanism 22 includes a first swing arm 221, a first roller 222, and a first driving block 223; one end of the first swing arm 221 is hinged to the support 21, and the first roller 222 is mounted on the first swing arm 221 and rotatably connected to the first swing arm 221; the first driving block 223 is mounted on the first swing arm 221, and the output end of the first driving block 223 is connected to the first roller 222, and the first driving block 223 is used to drive the first roller 222. Wheel 222 rotates; the bracket 21 is also provided with a first sliding rod 5; the first moving mechanism 22 further includes a first sliding block 224, a first screw 225, a second driving block 226, and a first connecting arm 227. The first sliding block 224 is disposed on the first sliding rod 5 and slidably connected to the first sliding rod 5; the first screw passes through the first sliding block 224 and is threadedly connected to the first sliding block 224; the second driving block 226 is disposed on the bracket 21, and the output end of the second driving block 226 is connected to one end of the first screw 225, and the second driving block 226 is used to drive the first screw 225 to rotate; one end of the first connecting arm 227 is hinged to the first sliding block 224, and the other end of the first connecting arm 227 is hinged to the first swing arm 221. Thus, through the design of the first swing arm 221 being hinged to the bracket 21 and the first connecting arm 227 being hinged at both ends, the cleaning mechanism 24 can adapt to pipes of different diameters.

[0029] like Figures 2-3As shown, in one embodiment, the second moving mechanism 23 includes a second swing arm, a second roller, and a second drive block 226. One end of the second swing arm is hinged to the bracket 21. The second roller is disposed on the second swing arm and rotatably connected to the second swing arm. The second drive block 226 is disposed on the second swing arm, and its output end is connected to the second roller. The second drive block 226 is used to drive the first roller 222 to rotate. The bracket 21 is also provided with a second slide rod. The second moving mechanism 23 further includes a second sliding block, a second screw, a third drive block, and a second connecting arm. The second sliding block is disposed on the second slide rod and slidably connected to the second slide rod. The second screw passes through the second sliding block and is threadedly connected to the second sliding block. The third drive block is disposed on the bracket 21, and its output end is connected to one end of the second screw. The third drive block is used to drive the second screw to rotate. One end of the second connecting arm is hinged to the second sliding block, and the other end of the second connecting arm is hinged to the second swing arm. Thus, through the design of the second swing arm being hinged to the bracket 21 and the second connecting arm being hinged at both ends, the cleaning mechanism 24 can adapt to pipes of different diameters.

[0030] like Figures 2-3 As shown, in one embodiment, the cleaning mechanism 24 includes a housing 241, a rotating disk 242, a rotating ring 243, a fourth drive block 244, and a plurality of blades 245. The housing 241 has a plurality of openings 6 for the blades 245 to pass through. One end of the blade 245 is hinged to the rotating disk 242, and the other end of the rotating disk 242 is hinged to the rotating ring 243. The rotating disk 242, the rotating ring 243, the fourth drive block 244, and the plurality of blades 245 are all disposed inside the housing 241. The output end of the fourth drive block 244 is connected to the rotating disk 242, and the fourth drive block 244 is used to drive the rotating disk 242 to rotate. The cleaning device 2 also includes a fifth drive block, which is disposed on the bracket 21. The output end of the fifth drive block is connected to the housing 241, and the fifth drive block is used to drive the housing 241 to rotate. Thus, when the blade 245 and the rotating disk 242 / rotating ring 243 adopt a double hinge design, the blade 245 can automatically retract to avoid encountering pipe wall protrusions or welds, and can also be adapted to water pipes of different diameters.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
