Description

Technical Field

[0001] The utility model belongs to the field of dust suppression, and particularly relates to dust suppression equipment for road construction. Background Art

[0002] With the acceleration of urbanization, road construction projects are increasing. These processes generate large amounts of dust, which not only poses a health threat to workers but also seriously affects the quality of life of surrounding residents. To reduce air pollution during construction, effective dust suppression measures are crucial.

[0003] Currently, the most common dust suppression method on the market involves using a sprinkler system to directly spray water into the air to suppress dust. While this method can alleviate dust on-site conditions to a certain extent, it has significant limitations: First, due to a lack of targeted design, the spray coverage is limited, making dust suppression ineffective, especially in high or hard-to-reach locations. Second, traditional spraying methods often consume large amounts of water, which is particularly wasteful given the increasing water scarcity. Finally, conventional sprinkler systems have a poor ability to capture fine particles, resulting in low overall dust suppression efficiency.

[0004] Therefore, developing a new dust suppression device that can both efficiently remove dust from construction sites and conserve water has become an urgent challenge. This invention aims to provide a dust suppression device for road construction that is structurally sound, easy to operate, and energy-efficient and environmentally friendly. By optimizing its design, it improves dust suppression efficiency while significantly reducing water consumption, providing an effective solution for improving air quality in construction environments. Utility Model Content

[0005] In order to solve the above technical problems, the present invention solves them through the following technical solutions.

[0006] A dust reduction device for road construction includes a water tank equipped with a dust removal wall panel. The dust removal wall panel includes an outer frame, within which a dust filter plate is mounted. Several first spray heads facing the dust filter plate are mounted on the front side of the dust removal wall panel above the dust filter plate. A slope is provided below the dust filter plate. The water tank is provided with an inflow trough that matches the slope. By assembling the dust removal wall panel with the dust filter plate on the water tank, dust generated during construction can be effectively captured and reduced, improving air quality at the construction site and protecting the health of workers and pedestrians. The water tank is connected to a circulation pipeline comprising an inlet pipe, a circulation pump, and an outlet pipe. The outlet pipe is connected to the first spray head, and the inlet pipe extends into the water tank. Water in the water tank returns to the water tank via the circulation pipeline, the first spray head, the dust filter plate, and the slope. This design enables the effective reuse of water resources, reduces water consumption, and ensures continuous and stable spraying operations.

[0007] Preferably, a guide plate is installed behind the dust filter plate, and guide pipes are evenly distributed on the guide plate. The diameter of the guide pipe facing the back of the dust removal wall panel is smaller than the diameter of the guide pipe facing the dust filter plate. This design can help accelerate the flow of air to the dust filter plate and improve the dust filter plate's ability to capture dust.

[0008] Preferably, the back of the dust removal wall panel is sealed and provided with an air outlet duct, and the air outlet duct is equipped with a blower. This design can create a negative pressure environment, accelerate the air circulation speed, further enhance the adsorption capacity of suspended particulate matter in the air, and improve the overall dust reduction effect.

[0009] Preferably, the dust removal wall panels are topped with several secondary sprinkler heads, each connected to a branch pipe that connects to the circulation line and is equipped with a branch switch to control water flow. This design allows for a wider coverage of the dust reduction area, particularly effective in high or hard-to-reach areas. Users can control the secondary sprinkler heads via the branch switch, reducing unnecessary waste.

[0010] Preferably, a slope is provided on the top of the dust removal wall panel, and the second sprinkler head is located on the slope, so that the second sprinkler head sprays toward the construction area to avoid wetting passers-by.

[0011] Preferably, the dust filter plate is a corrugated filter plate. The wavy surface of the corrugated aluminum plate increases the contact area and improves the ability to intercept tiny particles, thereby enhancing the overall filtering performance.

[0012] Preferably, the notch of the inflow trough is equipped with a filter plate to prevent larger debris such as fallen leaves from entering the circulation system and causing blockage and other problems, thereby ensuring the smooth operation of the entire system.

[0013] Compared with the prior art, this application has the following beneficial effects:

[0014] Compared with the existing technology, the dust reduction equipment for road construction provided by this application has the following significant advantages: large dust filtration area, high dust reduction efficiency, and water saving and environmental protection.

[0024] Reference Figures 1 to 3A dust suppression device for road construction includes a water tank 100, mounted on a dust removal wall panel 200. The dust removal wall panel 200 includes an outer frame 210, within which a dust filter plate 220 is mounted. A plurality of first spray heads 233 facing the dust filter plate 220 are mounted on the front side of the dust removal wall panel 200 above the dust filter plate 220. A slope 211 is provided below the dust filter plate 220, and the water tank 100 is provided with an inflow trough that matches the slope 211. By mounting the dust removal wall panel 200 with the dust filter plate 220 on the water tank 100, dust generated during construction can be effectively captured and reduced, improving the air quality at the construction site and protecting the health of workers and pedestrians. The water tank 100 is connected to a circulation pipeline, which includes an inlet pipe 230, a circulation pump 231, and an outlet pipe 232. The outlet pipe 232 is connected to the first spray head 233. The inlet pipe 230 extends into the water tank 100. Water in the water tank 100 returns to the water tank 100 through the circulation pipeline, the first spray head 233, the dust filter plate 220, and the slope 211. This design effectively reuses water resources, reduces water consumption, and ensures continuous and stable spraying operations.

[0025] Furthermore, the dust filter plate 220 is a corrugated filter plate. The wavy surface of the corrugated aluminum plate increases the contact area, improving the ability to intercept small particles, thereby enhancing overall filtration performance. The filter plate 110 is installed at the notch of the inflow trough to prevent larger debris such as fallen leaves from entering the circulation system and causing blockage, thereby ensuring smooth operation of the entire system.

[0026] To enhance the dust suppression capabilities of the dust suppression equipment, the dust removal wall panel 200 is equipped with several second sprinkler heads 235 on top. These second sprinkler heads 235 are connected to branch pipes 234, which are connected to the circulation pipeline and equipped with a branch switch to control the flow of water in these branches 234. The design of the second sprinkler heads 235 allows for a wider coverage of the dust suppression area, achieving excellent dust suppression effects even in high or hard-to-reach areas. Users can control the second sprinkler heads 235 via the branch switch to reduce unnecessary waste. The dust removal wall panel 200 is topped with a sloped surface 212, with the second sprinkler heads 235 positioned on this slope. This allows the second sprinkler heads 235 to spray towards the construction area, avoiding wetting passersby. When construction dust is generated in excess and exceeds the height of the dust suppression equipment, the branch switch can be turned on to enable the second sprinkler heads 235 to spray and capture dust above the dust suppression equipment.

[0027] In order to increase the flow rate of air through the dust filter plate 220, a guide plate 240 is installed behind the dust filter plate 220. The guide plate 240 is evenly distributed with guide pipes 241. The diameter of the guide pipe 241 facing the back of the dust removal wall panel 200 is smaller than the diameter of the side facing the dust filter plate 220. This design can help accelerate the flow of air to the dust filter plate 220 and improve the ability of the dust filter plate 220 to capture dust. The back of the dust removal wall panel 200 is closed and provided with an air outlet pipe 250, and the air outlet pipe 250 is equipped with a blower 251. This design can form a negative pressure environment, accelerate air circulation, further enhance the adsorption capacity of suspended particulate matter in the air, and improve the overall dust reduction effect.

[0028] Furthermore, to further enhance the operational convenience and intelligence of the dust suppression equipment, it is possible to consider integrating an automatic control system into the system. This system can automatically adjust the spray intensity and frequency based on the actual construction site conditions (such as dust concentration and wind speed) to achieve optimal dust reduction. Specifically, a dust sensor can be installed to monitor the particulate matter content in the surrounding air and transmit this data to the control system in real time. When the dust concentration in the air exceeds a preset threshold, the control system automatically activates or increases the spray intensity until air quality returns to safe standards. Conversely, in low-dust environments, the spray volume is appropriately reduced to conserve water resources.

[0029] Considering the importance of mobility and flexibility for road construction projects, the dust removal wall panels 200 and the water tank 100 can be designed into a modular structure for easy disassembly and transportation. The components are assembled using a quick connection method, so that even if the construction site is frequently moved between different locations, the construction work can be completed quickly, greatly improving work efficiency. At the same time, wheels can be added to the bottom of the water tank 100 to give it a certain degree of self-propelled ability, making it more convenient to adjust its position within a short distance. Through the above-mentioned improvement measures, not only can the performance of the dust reduction system be significantly enhanced, but its service life can also be effectively extended, maintenance costs can be reduced, and it can better serve various types of construction sites.

[0030] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention is based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field fall within the protection scope of the present invention.
