Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a dust removal device for building construction. Background Art

[0002] During the building construction process, a large amount of dust is often raised. The flying dust not only pollutes the urban environment but also endangers people's physical health. The state and construction departments have clearly stipulated that dust removal measures should be taken during construction to reduce the pollution of the urban air environment by the construction industry.

[0003] In the prior art, a water spraying device is often installed on the construction enclosure or a fog cannon vehicle is used to sprinkle water on the construction site for dust removal. Sprinkling water can increase the weight of dust particles, so that they settle to the ground, rapidly reduce the dust concentration in the air in a short time, and then improve the air quality at the construction site, which has an immediate effect on protecting the respiratory system of construction workers and reducing environmental pollution.

[0004] However, the water spraying method actually does not remove dust, but only temporarily deposits the dust on the ground. Once the water evaporates, the dust particles will be re-raised due to various external forces (such as wind, mechanical vibration, personnel activities, etc.), resulting in the recurrence of dust pollution problems. Summary of the Utility Model

[0005] The main object of the utility model is to propose a dust removal device for building construction, aiming to reduce the dust accumulation at the construction site and achieve the effect of effective dust removal.

[0006] To achieve the above object, a dust removal device for building construction proposed by the utility model includes:

[0030] The present invention provides a building construction dust removal device 100.

[0031] Please refer to Figure 1 , in an embodiment of the present invention, the building construction dust removal device 100 includes a mobile vehicle body 1, a dust removal box 2, a spray head 3, and a fan assembly 4. The dust removal box 2 is arranged on the mobile vehicle body 1. Inside the dust removal box 2, a first water storage chamber 21, a dust removal chamber 22, and a second water storage chamber 23 are sequentially formed from top to bottom and are separated from each other; the dust removal chamber 22 includes an air inlet chamber 221, a spray chamber 222, and an air outlet chamber 223 that are sequentially connected from left to right. Spray ports 24 and dust falling ports 25 for connecting the first water storage chamber 21 and the second water outlet chamber are respectively opened on the top wall and the bottom wall of the spray chamber 222. Air inlets 26 and air outlets 27 for connecting the air inlet chamber 221 and the air outlet chamber 223 are respectively opened on the outer side wall of the dust removal box 2; the spray head 3 is connected to the spray port 24 and is used for spraying water towards the direction of the dust falling port 25; the fan assembly 4 is used to guide the outside air to enter the dust removal chamber 22 through the air inlet 26 and guide the air in the dust removal chamber 22 to the outside through the air outlet 27.

[0032] The construction dust removal equipment 100 provided in this application sucks the air with dust from the outside into the dust removal box 2 through the fan assembly 4 via the air inlet 26. A spray head 3 is arranged inside the dust removal box 2, and the spray head 3 is connected to the first water storage cavity 21. When the air enters the dust removal box 2, the spray head 3 starts to work and sprays fine water droplets onto the air. These water droplets will combine with the dust particles in the air, increasing the weight of the dust, and thus settling into the second water storage cavity 23 through the dust fall opening 25. The air that has undergone the sprinkling spray and dust settlement treatment is relatively clean at this time and is discharged to the external environment by the fan assembly 4 through the air outlet 27 to achieve the function of dust removal and purification. The construction dust removal equipment 100 in this application can effectively remove the dust in the air, thereby improving the environmental quality of the construction site, protecting the health of construction workers, and at the same time reducing the impact of the construction site on the surrounding environment.

[0033] In an embodiment of this application, the construction dust removal equipment 100 further includes a first dust filter plate 5. At least part of the structure of the first dust filter plate 5 is arranged in the second water outlet cavity and below the dust fall opening 25 for filtering the water falling from the dust fall opening 25. The design and position of the first dust filter plate 5 enable it to effectively intercept and collect dust particles. These particles will fall together with the water droplets when falling from the dust fall opening 25. The water droplets can pass through the filter plate, while the dust particles are left on the filter plate. In this way, even fine dust particles can be effectively removed, improving the performance of the overall dust removal equipment. The filter plate is usually made of materials with fine pores, such as metal mesh, synthetic fiber cloth, or foam plastic, etc. These materials can allow water to flow through while capturing and blocking dust.

[0034] In order to maintain the efficiency of the first dust filter plate 5 and extend its service life, it is necessary to regularly clean and maintain the filter plate to remove the accumulated dust and prevent the pores from being blocked. Therefore, in an embodiment of this application, an installation opening 28 communicating with the second water outlet cavity is opened on the outer side wall of the dust removal box 2. Part of the structure of the first dust filter plate 5 can extend into the second water storage cavity 23 through the installation opening 28 so that the first dust filter plate 5 can span across the first water storage cavity 21 in the left - right direction. Specifically, the design of the installation opening 28 allows the operator to directly contact the first dust filter plate 5 from the outside of the dust removal box 2 without opening the internal structure of the dust removal box 2. When it is necessary to clean or replace the filter plate, the operator can easily extend a part of the filter plate into the second water storage cavity 23 through the installation opening 28 and then move it to the required position. In addition, the first dust filter plate 5 that can be replaced or detached improves the operation convenience of the equipment and also increases the maintainability of the equipment, thus helping to keep the dust removal equipment running efficiently.

[0035] In an embodiment of the present application, the construction dust removal device 100 further includes a support structure accommodated in the second water storage cavity 23. The support structure includes at least two support blocks 6, both of which are connected to the inner wall of the second water storage cavity 23. The two support blocks 6 are respectively located at the lower ends of both sides of the first dust filter plate 5 to support the first dust filter plate 5 upward. The support structure can provide sufficient support and stability for the installation of the first dust filter plate 5, preventing it from shifting or deforming due to the impact of water flow or other factors during use.

[0036] In an embodiment of the present application, the construction dust removal device 100 further includes a vacuum adsorber 7, and the vacuum adsorber 7 is arranged on the mobile vehicle body 1. After the operator pulls out the first dust filter plate 5 from the installation opening 28, the vacuum adsorber 7 generates a strong suction force to suck away the dust particles on the dust filter plate, thereby achieving cleaning.

[0037] In an embodiment of the present application, the construction dust removal device 100 further includes a circulation assembly 8. The circulation assembly 8 includes a pipeline 81 and a water pump 82. The pipeline 81 communicates the second water storage cavity 23 and the first water storage cavity 21, and the water pump 82 is used to introduce the water in the second water storage cavity 23 into the first water storage cavity 21. The water pump 82 can drain the filtered waste water in the second water storage cavity 23 back into the second water storage cavity 23 and spray it again by the spray head 3, which is convenient for subsequent reuse, avoids waste of water resources, helps improve the environmental protection performance of the device, and also reduces the water consumption at the construction site.

[0038] In an embodiment of the present application, the construction dust removal device 100 further includes a filter screen 9. The filter screen 9 is arranged in the dust removal box 2 and used to cover the air inlet 26. The function of the filter screen 9 is to preliminarily purify the inhaled air, prevent larger impurities (such as fallen leaves or garbage) from entering the interior of the dust removal box 2, thereby reducing the wear and maintenance requirements of the internal components of the device. The filter screen 9 is usually made of metal mesh, plastic mesh or other wear-resistant and corrosion-resistant materials, and has a small pore structure, which can effectively block larger impurities but allow air and dust to pass through.

[0039] In an embodiment of the present application, the cross-sectional area of the intake cavity 221 is gradually decreasing from left to right, that is, the cross-sectional area of the intake cavity 221 is in the shape of a horn. When the air with dust passes through the horn-shaped intake cavity 221, due to the gradual decrease in the cross-sectional area, the air flow velocity will gradually increase. This acceleration helps to increase the collision frequency between the dust particles and water droplets in the air, thereby improving the dust removal efficiency. In another embodiment of the present application, the cross-sectional area of the outlet cavity 223 is gradually increasing from left to right. When the purified air passes through the gradually increasing outlet cavity 223, the air flow velocity gradually slows down, which helps to reduce the disturbance to the surrounding environment and prevent the dust from being raised again, thereby reducing secondary pollution. Of course, in yet another embodiment of the present application, the cross-sectional area of the intake cavity 221 is gradually decreasing from left to right and the cross-sectional area of the outlet cavity 223 is gradually increasing from left to right.

[0040] In an embodiment of the present application, the fan assembly 4 includes an intake fan 41 and an exhaust fan 42. The intake fan 41 is disposed in the dust removal box 2 and located in the intake cavity 221, and the exhaust fan is disposed in the dust removal box 2 and located in the outlet cavity 223. The function of the intake fan 41 is to suck the air with dust from the outside into the dust removal box 2. The installation position of the intake fan 41 helps to ensure that the sucked air directly enters the dust removal box 2 and at the same time avoids the air from being mixed with the dust in the external environment again before entering the dust removal box 2. The function of the exhaust fan 42 is to discharge the dust-removed and purified air from the dust removal box 2 to the external environment. The installation position of the exhaust fan 42 helps to ensure that the discharged air directly exits from the dust removal box 2 and at the same time avoids the air from being mixed with the dust in the dust removal box 2 again before being discharged.

[0041] In an embodiment of the present application, the construction dust removal device 100 further includes a second dust filter plate 10. The second dust filter plate 10 is disposed on the inner wall of the spray cavity 222 and covers the connection between the spray cavity 222 and the outlet cavity 223. The second dust filter plate 10 is located at the connection between the spray cavity 222 and the outlet cavity 223, and can filter out the dust particles that are not captured by the first dust filter plate 5 during the spraying process, ensuring that the discharged air is cleaner. And since the second dust filter plate 10 is located in the spray cavity 222, the water sprayed by the spray head 3 can also spray and clean the dust on the second dust filter plate 10, so that the dust can still fall through the dust fall port 25.

[0042] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
