Description

Technical Field

[0001] The invention relates to the technical field of dust, and in particular to a device for suppressing dust diffusion in a tunnel. Background Art

[0002] Tunnels refer to engineering structures buried in the ground, and are a form of human use of underground space.

[0003] The Chinese patent number cited is CN218542307U, which discloses a tunnel face ventilation spray dust reduction device, including: a suspension component, a spray component, an air duct component and a power component. The suspension component is arranged on the vault of the inner wall of the tunnel. The suspension component is provided with a first hook, a first fixing device and a second hook. Several suspension components are arranged in sequence along the depth direction of the tunnel. The spray component is hung on the first fixing device. The end of the spray component close to the face is provided with a T-shaped atomizing spray section; the air duct component is hung on the second hook, the air outlet of the air duct component is lower than the T-shaped atomizing spray section, and the spray component is located above the air duct component, saving space in the tunnel. The spray component and the air duct component are combined together to achieve large-area distribution and effective migration of droplets.

[0004] The air circulation in the tunnel is poor, so dust will diffuse in the air of the tunnel and is difficult to dissipate. The presence of dust will affect the observation of the tunnel. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a device for suppressing dust diffusion in a tunnel to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a device for suppressing dust diffusion in a tunnel, comprising a frame, a mounting frame is fixedly connected to the top of the frame, a water tank is fixedly connected to the bottom of the frame, a processing chamber is fixedly connected to the left side of the water tank, an elastic band is fixedly connected to the left side of the processing chamber, a pipe is fixedly connected to the left side of the elastic band, a water inlet is opened on the top of the water tank, and a water mist mechanism is fixedly connected to the inner wall of the processing chamber;

[0007] The water mist mechanism comprises:

[0008] The first motor is fixedly connected to the inner wall of the processing bin, and the right side of the first motor is rotatably connected with a fan blade. When the airflow driven by the fan blade moves toward the left side of the pipeline, the airflow carries moisture and is discharged from the left side of the pipeline. The water mist adheres to the dust, thereby causing the dust to fall, thereby playing an effect of treating the dust in the air and accelerating the falling of the dust. The setting of the arc block further guides the airflow to pass through the top of the ash inlet hole. The setting of the arc block prevents the airflow from being blown out from the ash inlet hole, thereby facilitating the subsequent generation of a pressure difference effect. The airflow passes through the top of the ash inlet hole, thereby making the airflow velocity at the top of the ash inlet hole greater than the airflow velocity at the bottom of the ash inlet hole, thereby generating a pressure difference under the Bernoulli principle, and the air at the bottom of the ash inlet hole flows into the pipeline, and the dust in the air is mixed with the moisture in the pipeline, thereby accelerating the efficiency of treating the dust in the air;

[0009] A first rotating page, the left side of which is fixedly connected to the outer wall of the fan blade;

[0010] The first gear, the left side of the first gear is fixedly connected to the right side of the first rotating page, the size of the first gear is larger than the second gear, so when the first gear rotates one circle, the second gear rotates multiple circles, and the size difference between the gears is utilized, so a faster rotation is generated, ensuring that the water flow is dispersed, so that the airflow drives the water flow to spray out, and the airflow will drive the dispersed water to spray out from the pipe. When the water mixes with the dust, it will wet the dust and make the dust fall, ensuring the dust treatment effect and reducing the dust in the air. In the process of interlacing the first rotating page and the second rotating page, the water flow is located between the first hole and the second hole, which will further disperse the water, and under the impact of the first hole and the second rotating page, the water flow splashes into the pipe, and then drips from the ash inlet hole, and then the dust falls. Under the impact of the second rotating page, the water is spread on the inner wall of the pipe, and when the dust enters, it will adhere to the inner wall of the pipe, which accelerates the dust treatment efficiency.

[0011] Preferably, a first hole is formed on an outer wall of the first rotating page, and a second gear is meshedly connected to an outer wall of the first gear.

[0012] Preferably, a second rotating page is fixedly connected to the right side of the second gear, and a second hole is formed on the outer wall of the second rotating page.

[0013] Preferably, the right side of the second rotating leaf is rotatably connected to a bearing, and the bearing is fixedly connected to the inner wall of the processing chamber.

[0014] Preferably, an ash inlet hole is opened on the inner wall of the pipeline, and an arc block is fixedly connected to the inner wall of the pipeline at the position of the ash inlet hole.

[0015] Preferably, the outer wall of the pipe is fixedly connected with a swing mechanism, and the swing mechanism comprises a protruding block, and the protruding block is fixedly connected to the outer wall of the pipe.

[0016] Preferably, the outer wall of the frame is fixedly connected to a second motor, and the outer wall of the second motor is rotatably connected to an elliptical block. During the rotation of the elliptical block, the convex block will hit the protruding block, causing the protruding block and the pipe to descend. The elliptical setting of the elliptical block is utilized, so the protruding block will be continuously hit, causing the pipe to have a shaking effect. During the swinging process of the pipe, the dust adhered to the inner wall of the pipe will be driven to slide down from the pipe together with the moisture, thereby cleaning the dust adhered to the inner wall of the pipe and ensuring the continuous adhesion of dust in the pipe. The swinging of the pipe will change the direction of the airflow, thereby causing dust in more positions to fall. The change in the position of the pipe will further change the position of the ash inlet hole, thereby causing the ash inlet hole to suck dust from more positions, further reducing the presence of dust in the air. The elliptical block is in active contact with the protruding block, and a first spring is fixedly connected between the bottom of the frame and the outer wall of the pipe.

[0017] Preferably, a fanning plate is fixedly connected to the outer wall of the pipe, which will drive the fanning plate to follow and descend during the swinging process of the pipe. A baffle connected to a second spring is arranged at the bottom of the fanning plate. When the fanning plate descends, the airflow will be fanned downward, thereby causing the dust in the air to drop rapidly. The fanning of the fanning plate is utilized, so that after the dust comes into contact with moisture, the dust is accelerated to fall under the downward pressure of the airflow. An air inlet hole is provided on the outer wall of the fanning plate, and a bracket is fixedly connected to the outer wall of the fanning plate near the air inlet hole. The bottom of the bracket is fixedly connected to a second spring, and the bottom of the second spring is fixedly connected to the baffle.

[0018] The present invention provides a device for suppressing dust diffusion in a tunnel, which has the following beneficial effects:

[0019] 1. The device for suppressing dust diffusion in the tunnel, when the airflow driven by the fan blades moves toward the left side of the pipe, the airflow carries moisture and is discharged from the left side of the pipe, the water mist adheres to the dust, and then causes the dust to fall, which has the effect of treating the dust in the air and accelerating the falling of the dust. The setting of the arc block guides the airflow to pass through the top of the ash inlet hole. The setting of the arc block avoids the airflow from being blown out from the ash inlet hole, which is convenient for the subsequent pressure difference effect. The airflow passes through the top of the ash inlet hole, and then the airflow velocity at the top of the ash inlet hole is greater than the airflow velocity at the bottom of the ash inlet hole, and a pressure difference is generated under the Bernoulli principle. The air at the bottom of the ash inlet hole flows into the pipe, and the dust in the air is mixed with the moisture in the pipe, which accelerates the efficiency of treating the dust in the air.

[0020] 2. The device for suppressing dust diffusion in the tunnel has a first gear that is larger than the second gear. Therefore, after the first gear rotates one circle, the second gear rotates multiple circles. The size difference between the gears is utilized to generate a faster rotation, ensuring that the water flow is broken up, so that the airflow drives the water flow to spray out. The airflow drives the dispersed water to spray out from the pipe. When the water mixes with the dust, it will wet the dust and make the dust fall, ensuring the dust treatment effect and reducing the dust in the air. In the process of interlacing the first rotating page and the second rotating page, the water flow is located between the first hole and the second hole, which will further disperse the water. Moreover, under the impact of the first hole and the second rotating page, the water flow splashes into the pipe and then drips from the ash inlet hole, thereby causing the dust to fall. Under the impact of the second rotating page, the water is spread over the inner wall of the pipe. When the dust enters, it will adhere to the inner wall of the pipe, thereby accelerating the dust treatment efficiency.

[0021] 3. The device for suppressing dust diffusion in the tunnel can make the elliptical block hit the raised block during its rotation, causing the raised block and the pipe to drop. The elliptical setting of the elliptical block is utilized, so the raised block is continuously hit to make the pipe shake. During the swinging of the pipe, the dust and water adhering to the inner wall of the pipe are driven to slide down from the pipe, thereby cleaning the dust adhering to the inner wall of the pipe and ensuring the continuous adhesion of dust in the pipe. The swinging of the pipe will change the direction of the airflow, thereby causing the dust in more positions to fall. The change in the position of the pipe will cause the change in the position of the ash inlet hole, thereby causing the ash inlet hole to suck dust from more positions, further reducing the presence of dust in the air.

[0022] 4. The dust diffusion suppression device in the tunnel will drive the fan plate to follow the downward movement during the swinging of the pipeline. The baffle connected to the second spring is arranged at the bottom of the fan plate. When the fan plate descends, the airflow will be fanned downward, thereby causing the dust in the air to drop rapidly. The fanning of the fan plate is utilized to make the dust contact with moisture, and the descent of the dust is accelerated under the downward pressure of the airflow.

DETAILED DESCRIPTION

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] Embodiment 1

[0035] See also Figure 1-6 The present invention provides a technical solution: a device for suppressing dust diffusion in a tunnel, comprising a frame 1, a mounting frame 2 is fixedly connected to the top of the frame 1, a water tank 3 is fixedly connected to the bottom of the frame 1, a processing chamber 5 is fixedly connected to the left side of the water tank 3, an elastic band 11 is fixedly connected to the left side of the processing chamber 5, a pipe 6 is fixedly connected to the left side of the elastic band 11, a water inlet 4 is opened on the top of the water tank 3, and a water mist mechanism 7 is fixedly connected to the inner wall of the processing chamber 5;

[0036] The water mist mechanism 7 comprises:

[0037] A first motor 71, the first motor 71 is fixedly connected to the inner wall of the processing chamber 5, and a fan blade 72 is rotatably connected to the right side of the first motor 71;

[0038] A first rotating page 74, the left side of which is fixedly connected to the outer wall of the fan blade 72;

[0039] The first gear 77 , the left side of the first gear 77 is fixedly connected to the right side of the first rotating page 74 .

[0040] A first hole 73 is formed on an outer wall of the first rotating page 74 , and a second gear 78 is meshedly connected to an outer wall of the first gear 77 .

[0041] A second rotating page 76 is fixedly connected to the right side of the second gear 78 , and a second hole 75 is defined on an outer wall of the second rotating page 76 .

[0042] The right side of the second rotating page 76 is rotatably connected to a bearing 79 , and the bearing 79 is fixedly connected to the inner wall of the processing chamber 5 .

[0043] An ash inlet hole 9 is formed on the inner wall of the pipe 6 , and an arc block 10 is fixedly connected to the inner wall of the pipe 6 at the position of the ash inlet hole 9 .

[0044] When in use, water is added to the water tank 3 through the water inlet 4. The bottom of the water tank 3 is connected to the processing chamber 5 through a smaller hole, so the water in the water tank 3 will flow into the processing chamber 5. The power-on start of the first motor 71 drives the fan blade 72 to rotate, and the connection between the first rotating page 74 and the fan blade 72 will also be driven to rotate. The size of the first gear 77 is larger than the second gear 78. Therefore, when the first gear 77 rotates one circle, the second gear 78 rotates multiple circles, so it will drive the second rotating page 76 to rotate rapidly. The second rotating page 76 is installed in the processing chamber 5 through the bearing 79. The staggered rotation of the first rotating page 74 and the second rotating page 76 will hit the water in the processing chamber 5, and then disperse the water. The fan blade 72 rotates toward the left side to fan the airflow, and the airflow will drive the dispersed water to spray out from the pipe 6. When the water mixes with the dust, it will wet the dust and make the dust fall. In addition, the setting of the first hole 73 and the second hole 75 is on the first rotating page 74 and the second rotating page 7 6 staggered process, the water flow is located between the first hole 73 and the second hole 75, which will further disperse the water, and under the impact of the first hole 73 and the second rotating leaf 76, the water flow splashes toward the pipe 6, and then drips from the ash inlet hole 9, and then the dust falls. When the airflow fanned by the fan blade 72 moves toward the left side of the pipe 6, the airflow carries the moisture and is discharged from the left side of the pipe 6, and the water mist adheres to the dust, thereby causing the dust to fall. The setting of the arc block 10 further guides the airflow to pass through the top of the ash inlet hole 9. The airflow passes through the top of the ash inlet hole 9, and then the airflow velocity at the top of the ash inlet hole 9 is greater than the airflow velocity at the bottom of the ash inlet hole 9. According to Bernoulli's principle, the greater the airflow velocity, the smaller the pressure, so the air at the bottom of the ash inlet hole 9 will flow into the pipe 6, and then the dust in the air will mix with the moisture in the pipe 6, and the dust will either adhere to the inner wall of the pipe 6 or be discharged with the airflow. There is moisture in the pipe 6, so the dust entering the pipe 6 will adhere to moisture.

[0045] Embodiment 2

[0046] See also Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0047] The outer wall of the pipe 6 is fixedly connected with a swing mechanism 8 , and the swing mechanism 8 includes a protruding block 83 , and the protruding block 83 is fixedly connected to the outer wall of the pipe 6 .

[0048] The outer wall of the frame 1 is fixedly connected to a second motor 81 , the outer wall of the second motor 81 is rotatably connected to an elliptical block 82 , the elliptical block 82 is in active contact with a raised block 83 , and a first spring 84 is fixedly connected between the bottom of the frame 1 and the outer wall of the pipe 6 .

[0049] The outer wall of the pipe 6 is fixedly connected to a fan plate 12, and an air inlet hole 86 is opened on the outer wall of the fan plate 12. A bracket 87 is fixedly connected to the outer wall of the fan plate 12 near the air inlet hole 86. The bottom of the bracket 87 is fixedly connected to a second spring 85, and the bottom of the second spring 85 is fixedly connected to a baffle.

[0050] When in use, the processing chamber 5 is connected to the pipe 6 by an elastic band 11, which is made of elastic material, and the left side of the pipe 6 is connected to the frame 1 by the first spring 84, so that the left side of the pipe 6 can swing, and the second motor 81 is powered on to drive the elliptical block 82 to rotate. During the rotation of the elliptical block 82, it will hit the raised block 83, so that the raised block 83 and the pipe 6 will fall. After the pipe 6 falls, it will reset under the elastic pull of the first spring 84. During the swinging process of the pipe 6, the dust and moisture adhering to the inner wall of the pipe 6 will slide out of the pipe 6 together. The swing of pipe 6 will change the direction of airflow, so that dust in more positions will fall down. The change of position of pipe 6 will change the position of ash inlet hole 9, so that ash inlet hole 9 will suck dust in more positions. In addition, the swing of pipe 6 will drive fan plate 12 to follow and fall down. The baffle connected to the second spring 85 is set at the bottom of fan plate 12, so the baffle will fall down when fan plate 12 rises, so that airflow will pass through air inlet hole 86. Then, when fan plate 12 falls, it will fan the airflow down, so that the dust in the air will fall down quickly.
