Description

Technical Field

[0001] This utility model relates to the technical field of dust suppression devices, specifically a dust suppression device for highway engineering construction. Background Technology

[0002] With urban modernization, the highway construction industry is also constantly developing. During highway construction, construction machinery will raise a large amount of dust particles, which not only pollute the air, but also affect the health of construction workers and surrounding residents. Therefore, dust suppression devices are needed to purify the air. However, existing dust suppression devices for highway construction still have certain defects in use, such as:

[0003] Publication number CN117123016A proposes a dust suppression device for highway construction, comprising a trolley, a collection chamber fixedly installed on one side of the upper surface of the trolley, a stopper rod fixedly installed in the middle of the upper surface of the collection chamber, a vortex cavity fixedly installed at the top of the stopper rod, a first sleeve fixedly installed on the front side of the vortex cavity, a first sleeve rod slidably sleeved in the middle of the first sleeve, a suction head movably sleeved in the front side of the inner cavity of the first sleeve rod, a rotating tube mechanism provided between the collection chamber and the suction head, a driving mechanism provided on the upper surface of the collection chamber, a filtering mechanism provided in the inner cavity of the collection chamber, and a sedimentation mechanism provided between the upper surface of the trolley and the collection chamber. This solves the problem of existing water spray dust suppression devices where, after the water carrying dust drops onto the ground evaporates and dries, the dust is re-dispersed into the air, resulting in poor dust suppression effect and serious water waste. It also addresses the problems of narrow dust suppression range and low efficiency of existing dust suppression devices.

[0004] The aforementioned document states that dust-laden air is drawn into the device, and dust particles are filtered out using a first filter element to reduce dust and purify the air. However, when removing dust from the second filter element, circulating water is required. Not only does water need to be added, but the water level decreases continuously during circulation. At the same time, the filtered impurities accumulate in the second filter element, affecting the water circulation speed. Based on this, a dust suppression device for highway construction is proposed to solve the above problems. Utility Model Content

[0029] See Figures 1-3 and Figure 6It is known that the air intake mechanism 4 includes: a rotary compensator 401, a hose 402, an air intake hopper 403, a tray 404, a first threaded rod 405, a first slider 406, a transmission plate 407, a drive motor 408, a rectangular frame 409, a second threaded rod 410, a second slider 411, a guide groove 412, and a guide rod 413.

Then, starting the drive motor 408 causes the rectangular frame 409 to rotate. The rectangular frame 409 causes the guide rod 413 to slide within the guide groove 412, thereby causing the tray 404 and the hose 402 to rotate back and forth, allowing the dust suppression range of the highway construction dust suppression device to be adjusted.

[0031] In summary: When using this dust suppression device for highway construction, firstly, move the device to the construction site. Then, rotate the first threaded rod 405 to adjust the elevation angle of the air inlet hopper 403, and rotate the second threaded rod 410 to adjust the swing amplitude of the air inlet hopper 403. Next, operate the controller at the front of the housing 1 to start the exhaust fan 503, drawing dusty air from the outside into the air inlet hopper 403. The air then enters the housing 1 through the hose 402 and the rotary compensator 401, and after being filtered by the filter cloth 501 to remove dust and other impurities, the air exits from the exhaust fan. 503 is discharged, and impurities remain on the surface of the filter cloth cartridge 501. After long-term use, the air pump 507 is started to pressurize the air tank 508, and then the solenoid valve 509 is opened to spray high-pressure air from the nozzle 511, causing dust and other impurities on the surface of the filter cloth cartridge 501 to fall into the inner box 506. The cabinet door in front of the outer casing 1 is opened periodically, and the inner box 506 is pulled out and emptied to separate dust and other impurity particles in the air for dust reduction.
