Description

Technical Field

[0001] This utility model belongs to the technical field of dust control devices, and in particular relates to a dust control device for construction engineering. Background Technology

[0002] Dust pollution is a significant factor affecting the environment and human health during construction projects. Dust generated at construction sites not only reduces air quality but also poses health risks to construction workers and nearby residents, while exacerbating environmental pollution. Traditional dust control methods mainly include water spraying and covering with dust nets, but these methods suffer from limited coverage, low dust suppression efficiency, and water waste.

[0003] Among existing dust control devices, spray systems are common dust suppression equipment. However, they typically use nozzles at fixed angles, resulting in a limited spray range and difficulty in achieving multi-layered, all-around coverage. Furthermore, due to uneven nozzle height and water pressure distribution, some areas are easily over-sprayed while others are under-sprayed, affecting the dust suppression effect.

[0004] To address these issues, we provide a dust control device for construction projects. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a dust control device for construction engineering, comprising...

[0006] The load-bearing base is designed with an internally hollow structure.

[0007] The conveying pipes are evenly distributed in a circular array and run through the surface of the support base. The top of the pipes bends towards the outer circumference of the support base. Starting from the innermost circumference, the length of the conveying pipes decreases and the bending angle increases as they move towards the outermost circumference.

[0008] Atomizing nozzle is disposed through the top end of the delivery pipe;

[0009] The water pump, the outlet of which is connected to the inside of the load-bearing base via a flexible hose;

[0010] The water pump delivers water into the bearing seat and then upwards into the delivery pipe. When the water is ejected from the end of the delivery pipe, it presents a parabolic spray trajectory. The smaller the curvature of the delivery pipe, the greater the horizontal stroke of the water being sprayed.

[0011] The present invention is further configured such that, starting from the innermost circumference, the inner diameter of the conveying pipe increases towards the outermost circumference, and the water flow velocity inside decreases.

[0012] The present invention is further configured such that the conveying pipes arranged on two adjacent circumferences are staggered, and a single conveying pipe is located in the middle of two adjacent conveying pipes arranged on adjacent circumferences.

[0013] The present invention is further configured such that the circumference of the support seat near the surface is funnel-shaped, and the diameter is larger the closer to the surface of the support seat.

[0014] The present invention is further configured such that the distance from the starting point of the bending of the delivery pipe to the corresponding atomizing nozzle is different, and the bending distance is larger as it moves from the innermost circumference to the outermost circumference.

[0015] The present invention has the following beneficial effects: 1. Because the top of the conveying pipe is bent outward, when water is sprayed into the air, it presents a parabolic spray trajectory. The larger the bending angle, the shorter the distance of the parabolic trajectory in both the horizontal and vertical directions. Conversely, the smaller the bending angle, the longer the distance. As a result, the higher the top of the conveying pipe, the wider the spraying range. The spraying range of conveying pipes at different heights is different, and the spraying area of ​​the higher conveying pipe will cover the spraying area of ​​the lower one, achieving a multi-layer spraying effect and further improving the dust suppression efficiency.

[0016] 2. This utility model reduces the diameter of the inner circumference of the conveying pipe. At the same height, the smaller the diameter of the conveying pipe, the greater the speed of the water passing through it. This compensates for the loss of water flow velocity caused by the excessive length of the conveying pipe, and ensures that the water can run along a preset parabolic trajectory when it is sprayed out.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation

[0026] Please see Figure 1 This utility model is a dust control device for construction engineering, including a load-bearing base 1, which is configured as a hollow structure, and the load-bearing base 1 is placed on the ground.

[0027] The conveying pipe 2 is evenly distributed in a circular array and runs through the surface of the load-bearing base 1.

[0028] Atomizing nozzle 3 is disposed at the top of delivery pipe 2;

[0029] Water pump 4, the outlet of which is connected to the inside of the support base 1 via a flexible hose;

[0030] Specifically, when dust suppression is required, the water pump 4 is connected to the load-bearing seat 1 via a hose at its outlet and to an external water source via a hose at its pumping end. Then, the water pump 4 is started, which delivers water into the load-bearing seat 1 and upwards into the delivery pipe 2. The water is atomized through the atomizing nozzle 3 and finally sprayed out to suppress dust in the air.

[0031] For further details, please refer to Figure 2 The top of the conveying pipe 2 bends toward the outer periphery of the support seat 1. Starting from the innermost circumference, the length of the conveying pipe 2 decreases and the bending angle increases as it moves toward the outermost circumference.

[0032] The conveying pipe 2 is equipped with multiple sets of pipes of different lengths, which can suppress dust at different heights. The top of the pipe is bent outward to facilitate spraying water mist outward, thereby expanding the spraying area and improving the dust suppression effect.

[0033] Furthermore, because the top of the conveying pipe 2 bends outward, when water passes over its top, the direction of its force is obliquely upward. When it is sprayed into the air, it loses external force and presents a parabolic spray trajectory. The larger the bending angle, the smaller the angle between its force and the horizontal plane, and the shorter the distance of the parabolic trajectory in both the horizontal and vertical directions. Conversely, the larger the bending angle, the longer the distance. As a result, the higher the top of the conveying pipe 2, the wider the spraying range. The spraying range of conveying pipes 2 at different heights is different, and the spraying area of ​​the higher-positioned conveying pipe 2 will cover the spraying area of ​​the lower-positioned pipe, achieving a multi-layer spraying effect and further improving dust suppression efficiency.

[0034] For further details, please refer to Figure 3 Starting from the innermost circumference, the inner diameter of the conveying pipe 2 increases towards the outermost circumference, resulting in a lower water flow velocity inside. When water is transported to the top through the conveying pipe 2, it needs to overcome gravity to do work. Since the length of the conveying pipe 2 increases towards the innermost circumference, the water travels a longer distance, and the longer the length, the lower the final spray velocity. By reducing the diameter of the inner conveying pipe 2, at the same height, the water velocity passing through the smaller diameter conveying pipe 2 is greater, thus compensating for the loss of water flow velocity caused by the excessive length of the conveying pipe 2, and ensuring that the water can run along the preset parabolic trajectory when sprayed out.

[0035] For further details, please refer to Figure 3 The conveying pipes 2 arranged on two adjacent circumferences are staggered, and each conveying pipe 2 is located exactly in the middle of two adjacent conveying pipes 2 arranged on adjacent circumferences, such as... Figure 3 As shown, taking three delivery pipes 2 as an example, they are arranged in an equilateral triangle on the same circumference. The inner and outer pipes are arranged in an intersecting manner, so that the spraying area at the top of the delivery pipe 2 is staggered, thereby expanding the spraying area and the coverage of the water mist.

[0036] For further details, please refer to Figure 2 The circumference of the support seat 1 near the surface is set in a funnel shape, and the diameter is larger the closer to the surface of the support seat 1. By setting the funnel shape, when water moves to the surface of the support seat 1, the arc-shaped surface of its inner wall forms a guide for the water, dispersing the water at the top of the support seat 1, so that the water can flow evenly into each delivery pipe 2.

[0037] For further details, please refer to Figure 2 The distance from the starting point of the bend in the delivery pipe 2 to the corresponding position of the atomizing nozzle 3 is different. Starting from the innermost circumference, the bend distance is larger as it moves towards the outermost circumference. Since the water flow velocity in the inner delivery pipe 2 is greater, it is more likely to generate turbulence in the bend. By setting a longer bend, sufficient buffer time is given to the water flow, making the water flow more orderly when it reaches the atomizing nozzle 3.
