Description

Technical Field

[0001] This invention relates to the technical field of filtration and dust removal, specifically a mobile dust removal device for highway construction. Background Technology

[0002] With the continuous advancement of infrastructure construction, highway construction operations are becoming increasingly frequent, inevitably generating large amounts of dust and particulate matter during the process. This dust not only seriously pollutes the surrounding atmospheric environment and affects regional air quality, but also poses a threat to the health of on-site construction workers and may cause traffic safety hazards.

[0003] Currently, dust control during highway construction largely relies on traditional fixed dust suppression equipment or simple water spraying methods. Fixed equipment is inconvenient to install and difficult to move flexibly with the construction progress, resulting in a limited dust suppression range. While widely used water trucks or handheld sprayers have some mobility, they mainly rely on increasing air humidity to settle large particles, resulting in low efficiency in capturing fine dust particles that have already dispersed into the air. They also have problems such as high water consumption, creating muddy work surfaces, and failing to achieve resource-based dust collection. Although some mobile dust suppression vehicles integrate fans and filter units, they often need to be stopped during operation for filter cleaning or replacement, causing interruptions in dust suppression operations, affecting overall construction efficiency, and the frequent maintenance of filter media also increases operating costs.

[0004] Therefore, it is necessary to develop a dust removal equipment that can adapt to the dynamic changes in highway construction and can continuously remove dust at multiple points. Summary of the Invention

[0035] It should be noted that, in this embodiment, the housing 10 of the dust removal equipment can be installed on the mobile frame via the connector 11. The mobile frame can be a vehicle or other vehicle with transportation function.

[0036] During highway construction, a large amount of dust is generated due to excavation, slag transportation and other work. When using the dust removal equipment in the invention for dust removal, a camera can be installed on the housing 10. The controller receives the construction dust image information captured by the camera and obtains the dust area after analysis. At the same time, it triggers the moving frame to the designated position and adjusts the high-altitude dust collection device 30 and the low-altitude dust collection device 40 to the dust area, and the dust removal work can begin.

[0037] During dust removal, multiple suction components 26 are activated simultaneously. Dust-laden air enters the suction pipe 12 through the high-altitude suction device 30 or the low-altitude suction device 40, and then enters the dust filter pipe 24 through the second pipe 23. The pre-dust removal component 245 and the secondary dust removal component 246 in the dust filter pipe 24 sequentially filter the dust particles in the dusty air. The filtered air enters the suction component 26 and is discharged from the housing 10 through the exhaust end of the suction component 26.

[0038] When one of the dust filter tubes 24 needs to be self-cleaned, the electric control valve 232 on the corresponding conveying pipe 231 of the dust filter tube 24 is closed, and the switching component 25 switches the dust filter tube 24 to connect to the first tube 22, at which point the self-cleaning work can be performed.

[0039] During self-cleaning, the suction component 26 can backflush, and the impurities filtered by the pre-dust removal component 245 can enter the settling tank 21 through the first recovery pipe 221. The impurities filtered by the secondary dust removal component 246 can enter the settling tank 21 through the second recovery pipe 223.

[0040] Furthermore, when in use, the connector 11 includes two extended hanging ears symmetrically arranged at the bottom of the housing 10. The extended hanging ears are connected to the movable frame by screws to fix the housing 10.

[0041] Furthermore, when the switching component 25 is working, the actuator of the telescopic cylinder 251 drives the moving frame 252 to move, thereby realizing the movement of the dust filter pipe 24;

[0044] Furthermore, when the suction component 26 is working, the suction fan 262 is turned on, and the gas enters through the folded hose 263 and is discharged through the discharge pipe 264.

[0045] Furthermore, when the water mist component 27 is working, the liquid transfer pump 274 is turned on, and the liquid transfer pump 274 pumps the liquid in the water storage tank 273 into the water mist spray ring 271. The water mist spray ring 271 sprays out to form water mist, and the discharge pipe 264 sprays out gas and drives the water mist to be sprayed out from the spray pipe 272.

[0047] It should be noted that, in this embodiment, when the pre-dust removal component 245 is working, the pre-dust removal filter 2454 can filter the passing air. During the filtration process, the actuator of the bidirectional linear module 2456 can drive the drive frame 2455 to move, the drive frame 2455 drives the moving ring 2453 to move, and the moving ring 2453 drives the pre-dust removal filter 2454 to move, so that the pre-dust removal filter 2454 moves out of the jacket tube 2452, gradually increasing the effective filtration area of ​​the pre-dust removal filter 2454 and extending the filter's service life.

[0048] During self-cleaning, the actuator of the bidirectional linear module 2456 drives the pre-dust filter 2454 to reset.

The device includes a drive rod 36 slidably connected to the inner wall of the drive ring 34, a dust collection box 37 located at the end of the inclined rod 33, and a plurality of first funnel covers 38 located on the outer wall of the dust collection box 37 and connected to the dust collection box 37. The dust collection box 37 is connected to the suction pipe 12 through a pipe. The low-altitude vacuuming device 40 includes two first linear modules 41 symmetrically arranged on the outer wall of the housing 10, a suction frame 42 connected to the execution end of the first linear modules 41 on the outer wall, and a plurality of second funnel covers 43 located on the outer wall of the suction frame 42 and connected to the suction frame 42. The suction frame 42 is connected to the suction pipe 12 through a pipe.

[0052] It should be noted that, in this embodiment, when the high-altitude vacuuming device 30 is working, the actuator of the drive motor 31 can drive the turntable 32 to rotate, and the actuator of the power cylinder 35 can drive the drive rod 36 to rise and fall. The drive rod 36 drives the inclined rod 33 to rotate around its hinge point through the drive ring 34, so as to adjust the position of the vacuum box 37. Dust and gas enter the vacuum box 37 through the first funnel cover 38 and enter the suction pipe 12 through the pipe.

[0053] Furthermore, when the low-altitude dust collection device 40 is working, the actuator of the first linear module 41 drives the suction frame 42 to rise and fall, and the dust and gas enter the suction pipe 12 through the second funnel cover 43, the suction frame 42 and the pipe.

[0054] The working principle of this invention is as follows:

[0055] The housing 10 of the dust removal equipment can be mounted on a mobile frame via connector 11. The mobile frame can be a vehicle or other transport vehicle.

[0056] During highway construction, a large amount of dust is generated due to excavation, slag transportation and other work. When using the dust removal equipment in the invention for dust removal, a camera can be installed on the housing 10. The controller receives the construction dust image information captured by the camera and obtains the dust area after analysis. At the same time, it triggers the moving frame to the designated position and adjusts the high-altitude dust collection device 30 and the low-altitude dust collection device 40 to the dust area, and the dust removal work can begin.

[0057] During dust removal, multiple suction components 26 are activated simultaneously. Dust-laden air enters the suction pipe 12 through the high-altitude suction device 30 or the low-altitude suction device 40, and then enters the dust filter pipe 24 through the second pipe 23. The pre-dust removal component 245 and the secondary dust removal component 246 in the dust filter pipe 24 sequentially filter the dust particles in the dusty air. The filtered air enters the suction component 26 and is discharged from the housing 10 through the exhaust end of the suction component 26.

[0058] When one of the dust filter tubes 24 needs to be self-cleaned, the electric control valve 232 on the corresponding conveying pipe 231 of the dust filter tube 24 is closed, and the switching component 25 switches the dust filter tube 24 to connect to the first tube 22, at which point the self-cleaning work can be performed.

[0059] During self-cleaning, the suction component 26 can backflush, and the impurities filtered by the pre-dust removal component 245 can enter the settling tank 21 through the first recovery pipe 221. The impurities filtered by the secondary dust removal component 246 can enter the settling tank 21 through the second recovery pipe 223.

[0060] When in use, the connector 11 includes two extended hanging ears symmetrically arranged at the bottom of the housing 10. The extended hanging ears are connected to the movable frame by screws to fix the housing 10.

[0061] When the switching component 25 is working, the actuator of the telescopic cylinder 251 drives the moving frame 252 to move, so as to move the dust filter pipe 24;

[0062] When the dust filter pipe 24 is connected to the conveying pipe 231, the U-shaped sealing plate 253 can seal the first recovery pipe 221 and the second recovery pipe 223, and the sealing platform 222 can seal the dust discharge hole 244.

[0063] When the dust filter pipe 24 is connected to the first pipe 22, the horizontal pipe 242 is connected to the first recovery pipe 221, and the dust discharge hole 244 is connected to the second recovery pipe 223.

[0064] When the suction component 26 is working, the suction fan 262 is turned on, and the gas enters through the folded hose 263 and is discharged through the discharge pipe 264.

[0065] When the water mist component 27 is working, the liquid transfer pump 274 is turned on, and the liquid transfer pump 274 pumps the liquid in the water storage tank 273 into the water mist spray ring 271. The water mist spray ring 271 sprays out to form water mist, and the discharge pipe 264 sprays out gas and drives the water mist to be sprayed out from the spray pipe 272.

[0066] When the pre-dust removal component 245 is working, the pre-dust removal filter 2454 can filter the passing air. During the filtration process, the actuator of the bidirectional linear module 2456 can drive the drive frame 2455 to move. The drive frame 2455 drives the moving ring 2453 to move. The moving ring 2453 drives the pre-dust removal filter 2454 to move, so that the pre-dust removal filter 2454 moves out of the jacket tube 2452, gradually increasing the effective filtration area of ​​the pre-dust removal filter 2454 and extending the filter's service life.

[0067] During self-cleaning, the actuator of the bidirectional linear module 2456 drives the pre-dust filter 2454 to reset.

[0068] When the secondary dust removal component 246 is working, the dust filter bag 2462 filters the dust in the air;

[0069] During self-cleaning, the electric cylinder 2464 extends and retracts at the actuator end and drives the dust bag 2462 to shake through the guide rod 2465, thus discharging the dust from the dust bag 2462.

[0070] When the high-altitude vacuuming device 30 is working, the actuator of the drive motor 31 can drive the turntable 32 to rotate, and the actuator of the power cylinder 35 can drive the drive rod 36 to rise and fall.
