AI Technical Summary
In traditional smoke and dust suppression devices, the atomized water spraying position is set at the bottom of the cylinder, and the fan is installed inside the cylinder far away from the nozzle. This results in a long airflow path with obstructions, low guiding efficiency, and a small amount of water mist sprayed from a single atomizing nozzle with uneven particle size, making it difficult to form effective coverage over a large area and affecting the smoke and dust suppression effect.
The device employs a rotating fan blade driven by a dual-axis motor and multiple atomizing nozzles connected to a high-pressure pump. The rotating fan blades guide the atomized water at close range as it is sprayed out, while the dual atomizing nozzles create a counter-impact to refine the water mist, thus improving the diffusion and coverage of the atomized water.
By using the coordinated guidance of rotating fan blades and the opposing impact of dual atomizing nozzles, the guiding efficiency and coverage of the water mist are significantly improved, ensuring that the water mist can come into more full contact with dust particles, thus significantly improving dust suppression efficiency and quality.

Description
Technical Field
[0001] This utility model relates to the field of water mist fans, specifically a fine water mist fan for reducing smoke and dust. Background Technology
[0002] Industrial production, construction, and certain public activities often generate large amounts of smoke and dust. For example, in industrial production processes such as metal processing and coal combustion, high-temperature operations produce smoke components containing carbon particles and metal oxides; at construction sites, earthwork excavation and material handling operations raise large amounts of dust. This smoke and dust not only seriously pollute the air environment, reducing visibility and affecting normal production operations and personnel visibility, but also pose a threat to the health of workers and surrounding residents. Long-term exposure may cause respiratory and lung diseases. Therefore, dust suppression devices are needed. These devices spray water mist through water spray components to suppress dust in the environment.
[0003] According to publicly available patent CN220257548U, a rotating dust suppression device, belonging to the field of building engineering technology, addresses the problem that when existing water spray components rotate upwards, the water mist has to overcome gravity, resulting in a shorter horizontal spray distance and affecting the dust suppression distance. The device includes a dust suppression housing, a dust suppression rotating base, a dust suppression connecting shaft, a nozzle component, a dust suppression fan, a dust suppression moving mechanism, and a dust suppression range mechanism. The dust suppression rotating base is rotatably connected to the upper end face of the dust suppression housing; the dust suppression connecting shaft is fixedly connected to the inner end face of the dust suppression rotating base; the nozzle component is rotatably connected to the dust suppression connecting shaft; the dust suppression fan is rotatably connected inside the nozzle component; the dust suppression moving mechanism is located inside the dust suppression rotating base; and the dust suppression range mechanism is located inside the nozzle component. By employing the dust suppression moving mechanism, the dust suppression range of the device is increased; by employing the dust suppression range mechanism, the dust suppression distance is increased, while ensuring uniform water mist spraying at close range, thus improving the dust suppression efficiency of the device.
[0004] In traditional smoke and dust suppression devices, the airflow generated by a fan is typically used to guide atomized water to diffuse into the external space. These devices usually place the atomized water spray point at the bottom of the cylinder, while the fan is installed inside the cylinder, away from the nozzle. This layout results in low airflow efficiency when guiding the water mist due to the long airflow path and spatial obstruction. A large amount of water mist cannot be effectively delivered to the area requiring smoke and dust suppression. Furthermore, relying solely on a single atomizing nozzle results in a relatively small amount of water mist sprayed, making it difficult to achieve sufficient mist coverage density over a large area. Additionally, the generated water mist particles are not fine and uniform enough; larger particles settle quickly and cannot remain suspended in the air for long enough to fully contact and combine with smoke and dust, thus affecting the overall smoke and dust suppression effect. Therefore, a new technical solution is needed to address these issues. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of existing technologies, adapt to practical needs, and provide a fine water mist fan for smoke and dust suppression. This addresses the problem that in traditional smoke and dust suppression devices, the airflow generated by a fan is typically used to guide atomized water to diffuse into the external space. These devices usually place the atomized water spray position at the bottom of the cylinder, while the fan is installed inside the cylinder in a region far from the nozzle. This layout results in low efficiency in guiding the airflow to the water mist due to the long airflow path and spatial obstruction. A large amount of water mist cannot be effectively delivered to the area requiring smoke and dust suppression. Furthermore, relying solely on a single atomizing nozzle for spraying results in a relatively small amount of water mist, making it difficult to achieve sufficient water mist coverage density over a large area. Additionally, the resulting water mist particles are not fine and uniform enough; larger water mist particles settle quickly and cannot remain suspended in the air for a long time to fully contact and combine with smoke and dust, thus affecting the overall smoke and dust suppression effect.
[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a fine water mist fan for smoke reduction and dust removal is designed, including a water tank. A first fixing plate and a second fixing plate are fixed on the top two sides of the water tank, and a dust-reducing cylinder is provided between the first fixing plate and the second fixing plate. A mesh is installed at the openings at both ends of the dust-reducing cylinder. A dual airflow guiding component is provided inside the dust-reducing cylinder, and a counter-jet atomizing component is provided at both the front and rear ends of the water tank.
[0007] Preferably, the dual airflow guiding assembly includes a dual-axis motor located inside the dust collection cylinder. The output shafts at both ends of the dual-axis motor are connected to rotating rods via couplings, and a rotating fan blade is installed at one end of the rotating rod.
[0008] Preferably, one end of a fixing rod is fixed to both sides of the inner wall of the dust collection cylinder, and a dual-axis motor is fixed to the other end of the fixing rod.
[0009] Preferably, the through-beam atomizing assembly includes multiple high-pressure pump bodies, which are respectively connected to the bottom of the front and rear ends of the water tank.
[0010] Preferably, one end of the high-pressure pump body is connected to one end of a flexible hose, and the other end of the flexible hose is connected to an inclined tube installed in the partition net. The end of the inclined tube located inside the dust-suppressing housing is connected to an atomizing nozzle.
[0011] Preferably, a drive motor is installed on the outer side of the first fixing plate, and the output shaft of the drive motor passes through the first fixing plate to fix the dust collection cylinder. A bearing is installed on the inner side of the second fixing plate, and a connecting rod is rotatably connected inside the bearing. The other end of the connecting rod is fixed to the dust collection cylinder.
[0012] Preferably, the top and side of the water tank are connected to one end of a water pipe, the other end of the water pipe is detachably connected to a pipe cover, and the bottom of the water tank is equipped with wheels at the four corners.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model combines a dust suppression cylinder, a dual-axis motor, and rotating fan blades. The output shafts of the dual-axis motor are each connected to a rotating fan blade, placing multiple rotating fan blades at opposite ends of the dust suppression cylinder. During atomized water dust suppression, the rotating fan blade closest to the atomized water nozzle, being closer to the nozzle, can directly guide the atomized water at close range as soon as it is sprayed, allowing the water mist to diffuse rapidly and efficiently in the predetermined direction. This avoids disorderly dispersion of the water mist inside the cylinder and improves the initial guiding efficiency of the water mist. Simultaneously, the rotating fan blades near the outlet of the dust suppression cylinder, when the atomized water quickly reaches the cylinder opening under the guidance of the first rotating fan blade, will further guide the atomized water. This device guides the water mist more precisely and powerfully into the external environment. Through the coordinated and relay-guided operation of rotating fan blades at both ends, it greatly enhances the guiding effect of the atomized water, ensuring that the water mist can more fully cover the dust suppression area, thereby improving the overall dust suppression efficiency and quality. This solves the technical problem that in current traditional smoke and dust suppression devices, the airflow is generally guided by the wind power generated by the fan to diffuse the atomized water into the external space. These devices usually place the spray position of the atomized water at the bottom of the cylinder, while the fan is installed in the cylinder in an area far away from the nozzle. This layout structure results in a relatively low guiding efficiency of the airflow on the water mist when it acts on the water mist, due to the long airflow path and certain spatial obstruction. A large amount of water mist cannot be effectively delivered to the area that needs dust and smoke suppression.
[0015] 2. This utility model combines a high-pressure pump body, an inclined tube, and an atomizing nozzle, employing dual atomizing nozzles for atomization. This directly and significantly increases the total atomization volume and the atomized coverage area, enabling the formation of a denser and wider water mist barrier in a shorter time, providing more abundant water mist resources for dust suppression. Furthermore, the inclined tube and nozzle are set at mutual inclination inside the dust suppression cylinder. When both atomizing nozzles spray atomized water simultaneously, the tilted angle causes the two streams of water to impact each other, further spreading the atomized water during the collision process. This further refines the originally larger water mist particles. By transforming the water into tiny droplets, not only is the atomization effect enhanced, but the finer and more uniform water mist can also more fully contact and combine with dust particles in the air, thereby significantly improving dust suppression efficiency. This solves the technical problems of relying solely on a single atomizing nozzle for spraying operations. On the one hand, the amount of water mist sprayed is relatively small, making it difficult to form sufficient water mist coverage density in a large space. On the other hand, the water mist particles produced are not fine and uniform enough, and the larger water mist particles settle quickly, making it difficult to remain suspended in the air for a long time to fully contact and combine with smoke and dust, thus affecting the overall smoke and dust suppression effect.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0021] Example 1: A fine water mist fan for smoke reduction and dust removal, see [link to example]. Figures 1 to 3The system includes a water tank 1, with a first fixing plate 101 and a second fixing plate 102 fixed on the top two sides of the water tank 1, respectively. A dust-suppressing cylinder 2 is disposed between the first fixing plate 101 and the second fixing plate 102. A mesh screen 201 is installed at the openings at both ends of the dust-suppressing cylinder 2. A dual airflow guiding component is disposed inside the dust-suppressing cylinder 2. A jet atomizing component is disposed at both the front and rear ends of the water tank 1. When performing atomized water-guided dust suppression operation, the dual-shaft motor 202 is started. The motor starts running and synchronously drives the rotating fan blades 204 at both ends to rotate. The rotating fan blade 204 near the atomized water nozzle can directly guide the atomized water as soon as it is sprayed from the nozzle. At this time, the rotating fan blade 204... The generated airflow acts on the newly formed water mist, enabling it to spread rapidly and efficiently along a predetermined direction. This avoids the disorderly dispersion of water mist inside the cylinder due to a lack of effective guidance, greatly improving the initial guidance efficiency of the water mist and ensuring that the water mist can quickly enter an effective dust suppression path after leaving the nozzle. At the same time, the rotating fan blade 204 located near the outlet of the dust suppression cylinder 2 also operates synchronously under the drive of the dual-axis motor 202. When the atomized water reaches the cylinder opening position at a relatively fast speed under the guidance of the first rotating fan blade 204, the rotating fan blade 204 near the outlet immediately takes effect to provide secondary guidance for the atomized water that is about to leave the cylinder. By pushing water mist more precisely and powerfully into the external environment through the coordinated and relay-guided operation of the rotating fan blades 204 at both ends, a continuous and efficient water mist guidance system is formed. The water mist undergoes two guidance processes within the cylinder, improving its diffusion range and coverage. This allows for more thorough coverage of the dust suppression area, enabling airborne dust particles to fully contact and combine with more water mist, thus settling down. This effectively improves the overall dust suppression efficiency and quality. It also solves the technical problem in traditional smoke and dust suppression devices, which typically rely on the wind power generated by a fan to guide the atomized water to the external space. These devices usually place the atomized water spray position at the bottom of the cylinder, while the fan is installed in an area inside the cylinder far from the nozzle. This layout results in a relatively low guiding efficiency of the airflow when it acts on the water mist due to the long airflow path and certain spatial obstructions. A large amount of water mist cannot be effectively delivered to the area requiring dust and smoke suppression.
[0022] For details, see Figure 2 The dual airflow guiding component includes a dual-axis motor 202, which is located inside the dust collection cylinder 2. The output shafts at both ends of the dual-axis motor 202 are connected to a rotating rod 205 via a coupling. A rotating fan blade 204 is installed at one end of the rotating rod 205.
[0023] Further, see Figure 2 The dust collection cylinder 2 has a fixed rod 203 fixed on one end on each side of its inner wall, and a dual-axis motor 202 fixed on the other end of the fixed rod 203.
[0024] It is worth noting that, see Figure 1 The atomizing component includes multiple high-pressure pump bodies 3, which are respectively connected to the bottom of the front and rear ends of the water tank 1.
[0025] It is worth noting that, see Figure 3 One end of the high-pressure pump body 3 is connected to one end of a hose 301, and the other end of the hose 301 is connected to an inclined tube 302 installed inside the partition net 201. The inclined tube 302, located inside the dust-suppressing housing, is connected to an atomizing nozzle 303. When atomized water is generated, multiple high-pressure pump bodies 3 are first activated. The high-pressure pump body 3 draws water from the water tank 1 and pressurizes it. Then, through the connected hose 301, the high-pressure water is delivered to multiple atomizing nozzles 303 located inside the dust-suppressing cylinder 2. Because dual atomizing nozzles 303 are used for atomization, the amount of atomized water is significantly increased. Furthermore, the inclined tube 302 and the nozzles are set at an angle to each other inside the dust-suppressing cylinder 2. When two atomizing nozzles are used... When nozzle 303 sprays atomized water simultaneously, due to the tilt angle between the inclined tube 302 and the nozzle, the two streams of atomized water will form a counter-impact during the spraying process. When they collide with each other, the strong impact force causes the two streams of atomized water to spread further. The originally relatively large water mist particles are further refined into tiny water droplets under the violent action of the collision. After being refined by the counter-impact, the atomization effect is enhanced. The finer and more uniform water mist has a larger specific surface area, which can more fully contact and combine with dust particles in the air. After the dust particles are wrapped by the tiny water droplets, their weight increases, making it easier for them to settle to the ground, thereby greatly improving the dust reduction efficiency and effectively improving air quality.
[0026] It is worth mentioning that, see Figure 1 A drive motor 103 is installed on the outer side of the first fixed plate 101. The output shaft of the drive motor 103 passes through the first fixed plate 101 and is fixed to the dust collection cylinder 2. A bearing 104 is installed on the inner side of the second fixed plate 102. A connecting rod 105 is rotatably connected inside the bearing 104. The other end of the connecting rod 105 is fixed to the dust collection cylinder 2.
[0027] It is worth emphasizing that, see Figure 1 The top and side of the water tank 1 are connected to one end of a water pipe 107, and the other end of the water pipe 107 is detachably connected to a pipe cover 108. The bottom of the water tank 1 is equipped with a rotating wheel 106 at each of the four corners.
[0028] When using a fine water mist fan for smoke and dust suppression, the dual-axis motor 202 is started. The motor begins to run and synchronously drives the rotating fan blades 204 at both ends to rotate. The rotating fan blade 204 near the atomizing water nozzle can directly guide the atomizing water as soon as it is sprayed from the nozzle. At this time, the airflow generated by the rotating fan blade 204 acts on the newly formed water mist, enabling the water mist to spread quickly and efficiently along the predetermined direction. This avoids the disorderly dispersion of water mist inside the cylinder due to lack of effective guidance, greatly improving the initial guidance efficiency of the water mist and ensuring that the water mist can quickly enter the effective dust suppression path after leaving the nozzle. At the same time, the rotating fan blade 204 located near the outlet of the dust suppression cylinder 2 also runs synchronously under the drive of the dual-axis motor 202. When the atomizing water reaches the opening of the cylinder at a relatively fast speed under the guidance of the first rotating fan blade 204, the rotating fan blade 204 near the outlet immediately plays a role in guiding the atomizing water that is about to leave the cylinder a second time. The water mist is pushed more precisely and powerfully into the external environment through the coordinated and relay-guided operation of the rotating fan blades 204 at both ends, forming a continuous and efficient water mist guidance. The water mist undergoes two guidance processes within the cylinder, improving its diffusion range and coverage, enabling more thorough coverage of the dust suppression area. This allows more dust particles in the air to come into full contact with and combine with the water mist, thus settling down and effectively improving the overall dust suppression efficiency and quality. When generating atomized water, multiple high-pressure pumps 3 are first activated. The high-pressure pumps 3 draw water from the water tank 1 and pressurize it, then deliver the high-pressure water flow to multiple atomizing nozzles 303 located inside the dust suppression cylinder 2 through the connected hoses 301. Due to the use of dual atomizing nozzles 303 for atomization, the amount of atomized water is significantly increased. Furthermore, the inclined tube 302 and the nozzle are set at an angle to each other inside the dust suppression cylinder 2. When the two atomizing nozzles 303 spray atomized water simultaneously, the two streams of atomized water will form a counter-impact during the spraying process due to the angle between the inclined tube 302 and the nozzle. When they collide, the strong impact force causes the two streams of atomized water to spread further. The originally relatively large water mist particles are further refined into tiny water droplets under the violent impact. After being refined by the counter-impact, the atomization effect is enhanced. The finer and more uniform water mist has a larger specific surface area, which can more fully contact and combine with the dust particles in the air. After the dust particles are wrapped by the tiny water droplets, their weight increases, making it easier for them to settle to the ground, thereby greatly improving the dust suppression efficiency and effectively improving air quality.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
