Description

Technical Field

[0001] The invention relates to the technical field of dust reduction during bridge construction, and in particular to a vehicle-mounted dust removal and purification device for municipal bridge construction. Background Art

[0002] The purpose of dust reduction is to effectively prevent and control dust pollution around the construction site, improve the quality of environmental air, ensure the normal production, living order and health of the people, and prevent environmental pollution accidents during the construction process. At present, most construction sites use fog cannons for dust reduction. Fog cannons are what we call air-transported sprayers. They use the micron-sized particles produced by the spray to spray into the air to absorb various sizes of dust particles in the air faster and more effectively, forming effective dust reduction. The fog cannon has a long range, a wide coverage area, high working efficiency, and can achieve precise spraying. The sprayed fog particles are small. When they come into contact with dust, they form a wet mist that can quickly suppress dust. It is flexible to operate and can be remotely or manually controlled. The horizontal rotation and spray angle can be adjusted at will, making it safe and reliable to use.

[0003] During the use of existing dust suppression equipment, the spraying range of the nozzle is relatively fixed, and the range of the generated water mist spray is single. When the water mist spraying range needs to be increased, the spraying direction of the fog cannon needs to be continuously adjusted, and the operator needs to operate the fog cannon, resulting in poor dust suppression effect. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A vehicle-mounted dust removal and purification device for municipal bridge construction, comprising a cart, wherein a base is fixedly connected to the middle of the top of the cart;

The spray range and angle of the water spray can be changed as needed, which can increase the flexibility of the dust reduction machine, enable it to handle difficult-to-reach areas, and improve the overall purification effect. The top of the cylinder is fixedly connected to the dust reduction component, and the connecting plate is away from the motor. One end of the cylinder is fixedly connected to a bracket. During the dust reduction process, the motor is connected to an external power supply, and the motor drives the turntable to rotate. The turntable drives the dust reduction assembly to rotate 360 ​​degrees through the connecting plate. At the same time, the cylinder works to push the dust reduction assembly to rotate around the bracket, thereby adjusting the inclination direction of the dust reduction assembly, so that the spraying direction and angle of the water mist can be adjusted efficiently, so as to achieve rapid dust reduction of air dust in spaces at different heights, improve the spraying efficiency, expand the spraying range, and facilitate use in various environments. The bracket is rotatably connected to the dust reduction assembly, and the middle part of the bracket is rotatably connected to a rotating shaft, and the rotating shaft is fixedly connected to the outer side of the dust reduction assembly, and one end of the bracket away from the connecting plate is fixedly connected to a limited position assembly, and the bracket is set to a triangle;

The dust reduction assembly is driven to rotate by the cylinder, and the dust reduction assembly drives the outer rotating shaft to rotate on the bracket. At this time, the rotating shaft drives the rotating rod to rotate, and the rotating rod drives the connecting ring to rotate. At this time, the round rod inside the connecting ring drives the semicircular plate to rotate inside the fixing ring. When the semicircular plate contacts and squeezes the limiting block, the elastic properties of the spring plate are used to make the semicircular plate pass through the limiting block smoothly, thereby adjusting the inclination angle of the dust reduction assembly, which can improve the water spray coverage and purification effect, can more comprehensively cover the area that needs to be purified, and reduce water spray blind spots or loopholes. When the tilting angle is adjusted, the semicircular plate is located in the middle of two adjacent limit blocks. The two limit blocks limit the semicircular plate to prevent the dust reduction component from rotating at an tilting angle due to a cylinder failure during the dust reduction process, which results in a poor dust reduction effect. A through hole is provided inside the connecting ring, and the through hole is set to a trapezoid. A spring plate is clamped on the inner wall of the through hole. A round rod is fixedly connected to the middle of the spring plate, and the semicircular plate is fixedly connected to one end of the round rod away from the spring plate. The fixing ring is fixedly connected to a limiting block on a side close to the connecting ring. There are multiple limit blocks, and the multiple limit blocks are evenly distributed around the rotating shaft, and the semicircular plate is located in the middle of two adjacent limit blocks. A connecting rod is fixedly connected to the outer side of the fixing ring, and both ends of the connecting rod are fixedly connected to the fixing ring and the connecting ring.

At this time, the high-speed airflow generated by the fan further disperses and diffuses the droplets sprayed by the spray assembly so that they can be evenly distributed over a larger range, the transmission member passes through the cylinder and extends to the interior of the cylinder, the fan is located inside the cylinder, the inner wall of the cylinder is fixedly connected to the spray assembly, and the spray assembly is located between the fan and the adjusting assembly.

[0009] Preferably, the spray assembly includes a water pipe, which passes through the cylinder and extends to the interior, one end of the water pipe is fixedly connected to a ring, the ring is located inside the cylinder, the ring is fixedly connected to the inner wall of the cylinder, the outer side of the ring is fixedly connected to a shell, the shell is arranged in a stepped shape, and the outer side of the shell away from the ring is provided with a discharge port, there are multiple discharge ports, and the multiple discharge ports are evenly distributed on the outer side of the shell, and the top of the shell is fixedly connected to a shell, when the speed of the motor increases, the speed of the fan increases, so that the flow rate of the airflow increases, the airflow drives the flow of gas near the discharge port on the shell, and the fast-flowing airflow generates shear force on the liquid or particles sprayed from the nozzle, and this shear force can make the liquid or particles more dispersed during the spraying process, reduce the possibility of their agglomeration, thereby improving the efficiency and rate of spraying, and the faster the airflow velocity, the formation of a local low pressure around the discharge port The pressure area, according to Bernoulli's principle, when the fluid speed increases, the pressure will decrease. At this time, the water flow rate inside the shell becomes faster, and the force on the positioning block by the fluid increases. The positioning block slides downward on the outside of the rotating shaft, so that the gap between the limit ring and the positioning block becomes smaller, so that the water pressure becomes larger, the droplets become smaller, and the dust reduction effect is improved. The shell is fixedly connected to the inside of the limit ring, and a positioning block is arranged inside the limit ring. The outside of the positioning block is fixedly connected with an elastic plate, and the end of the elastic plate away from the positioning block is fixedly connected to the shell. The middle part of the positioning block is slidably connected with a rotating shaft. When water flows, the rotating plate is driven to rotate under the action of the flow of the fluid, and the rotating plate drives the rotating shaft to rotate, so that the rotating shaft drives the rotating plate to rotate, guiding the flow direction of water, avoiding the inlet of the shell from being subjected to force, and reducing the service life of the shell. The outer side of the rotating shaft near the discharge port is fixedly connected with a rotating plate, and the outer side of the rotating shaft near the shell is fixedly connected with a rotating plate.

Therefore, when the airflow passes through the hollow frustum cylinder with a smaller diameter formed by the extension cylinder, the pressure of the airflow is greater, and the airflow can drive the fog group to fly a farther distance, so that the range of the dust reduction component can be increased. Without increasing the power of the fan, the range of the dust reduction component is increased, and the adjustment method is more economical and practical. At the same time, the length of the straight cylinder is extended by setting the extension cylinder, so that the air outlet The pressure is not dispersed, which is suitable for narrowing the range and precise dust reduction.

By arranging the spiral plate and the limit rod, the gas can be evenly mixed with the sprayed droplets, and at the same time, the gas drives the droplets to collide with the limit rod to generate a large number of bubbles. The bubbles greatly increase the overall surface area of ​​the water mist, increase the contact area with the dust, and increase the viscosity of the bubbles, thereby improving the overall dust reduction efficiency.

[0011] The present invention provides a vehicle-mounted dust removal and purification device for municipal bridge construction. It has the following beneficial effects:

[0012] 1. The vehicle-mounted dust removal and purification equipment for municipal bridge construction uses a cylinder to adjust the inclination angle of the water mist sprayed by the dust reduction component to ensure that the sprayed water mist can reach the target area and improve the cleaning efficiency. The spray range and angle of the water spray can be changed as needed, which can increase the flexibility of the dust reduction machine, enable it to handle difficult-to-reach areas, and improve the overall purification effect.

[0013] 2. The vehicle-mounted dust removal and purification equipment for municipal bridge construction can efficiently adjust the spray direction and angle of the water mist by setting a base, so as to achieve rapid dust reduction of air dust in spaces at different heights, improve the spraying efficiency, expand the spraying range, and facilitate use in various environments.

[0014] 3. The vehicle-mounted dust removal and purification equipment for municipal bridge construction uses the elastic properties of the spring plate to allow the semicircular plate to pass through the limit block smoothly, thereby adjusting the inclination angle of the dust reduction component, which can improve the water spray coverage and purification effect, and can more comprehensively cover the area that needs to be purified, reducing the occurrence of water spray dead angles or loopholes. After adjusting the inclination angle, the semicircular plate is located in the middle of two adjacent limit blocks. The semicircular plate is limited by two limit blocks to prevent the dust reduction component from rotating at an inclination angle due to cylinder failure during the dust reduction process, resulting in poor dust reduction effect.

[0015] 4. The vehicle-mounted dust removal and purification equipment for municipal bridge construction generates shear force on the liquid or particles sprayed from the nozzle through the fast-flowing airflow. This shear force can make the liquid or particles more dispersed during the spraying process, reduce the possibility of their agglomeration, and thus improve the efficiency and rate of spraying.

[0016] 5. The vehicle-mounted dust removal and purification equipment for municipal bridge construction will form a local low-pressure area around the discharge port as the air flow velocity increases. According to Bernoulli's principle, when the fluid velocity increases, the pressure will decrease. At this time, the water flow velocity inside the shell becomes faster, and the force of the fluid on the positioning block increases. The positioning block slides downward on the outside of the rotating shaft, making the gap between the limit ring and the positioning block smaller, thereby increasing the water pressure, reducing the droplets, and improving the dust reduction effect.

[0030] A dust reduction component 3, the dust reduction component 3 is fixedly connected to the top of the base 2;

[0031] Among them, the base 2 includes a bottom plate 21, which is fixedly connected to the middle of the top of the cart 1, and a motor 22 is fixedly connected inside the bottom plate 21. The output end of the motor 22 passes through the bottom plate 21, and the top of the bottom plate 21 is rotatably connected to a turntable 23, and the output end of the motor 22 is fixedly connected to the bottom of the turntable 23. The turntable 23 is fixedly connected to a connecting plate 24 on the side away from the motor 22, and the top of the connecting plate 24 is fixedly connected to a cylinder 25. The inclination angle of the water mist sprayed by the dust removal component 3 is adjusted by the cylinder 25 to ensure that the sprayed water mist can reach the target area and improve the cleaning efficiency. The spray range and angle of the water spray can be changed as needed, which can increase the flexibility of the dust removal machine, enable it to handle difficult-to-reach areas, and improve the overall purification effect. The top of the cylinder 25 is fixedly connected to the dust removal component 3, and the connecting plate 24 is away from the cylinder 25. One end is fixedly connected with a bracket 26. During the dust reduction work, the motor 22 is connected to an external power supply, and the motor 22 drives the turntable 23 to rotate. The turntable 23 drives the dust reduction component 3 to rotate 360 ​​degrees through the connecting plate 24. At the same time, the cylinder 25 works to push the dust reduction component 3 to rotate around the bracket 26, thereby adjusting the inclination direction of the dust reduction component 3, so that the spraying direction and angle of the water mist can be adjusted efficiently, so as to realize rapid dust reduction of air dust in spaces of different heights, improve the spraying efficiency, expand the spraying range, and facilitate use in various environments. The bracket 26 is rotatably connected to the dust reduction component 3, and the middle part of the bracket 26 is rotatably connected with a rotating shaft 28, and the rotating shaft 28 is fixedly connected to the outer side of the dust reduction component 3. The end of the bracket 26 away from the connecting plate 24 is fixedly connected to the limiting component 27, and the bracket 26 is set as a triangle;

[0032] The limiting assembly 27 includes a fixing ring 271, which is fixedly connected to the bracket 26, and the center of the fixing ring 271 coincides with the axis of the rotating shaft 28. A rotating rod 274 is fixedly connected to the outer side of the rotating shaft 28, and a connecting ring 275 is fixedly connected to the end of the rotating rod 274 away from the rotating shaft 28. The dust removal assembly 3 is driven to rotate by the cylinder 25, and the dust removal assembly 3 drives the outer rotating shaft 28 to rotate on the bracket 26. At this time, the rotating shaft 28 drives the rotating rod 274 to rotate, and the rotating rod The connecting ring 274 drives the connecting ring 275 to rotate. At this time, the round rod 278 inside the connecting ring 275 drives the semicircular plate 279 to rotate inside the fixing ring 271. When the semicircular plate 279 contacts and squeezes the limit block 272, the elastic performance of the spring plate 277 is used to make the semicircular plate 279 pass through the limit block 272 smoothly, thereby adjusting the inclination angle of the dust suppression component, which can improve the water spray coverage and purification effect, can more comprehensively cover the area that needs to be purified, and reduce the dead angle or leakage of water spray. The hole is produced, and after the tilt angle is adjusted, the semicircular plate 279 is located in the middle of the two adjacent limit blocks 272. The two limit blocks 272 limit the semicircular plate 279 to prevent the dust reduction component 3 from tilting and rotating due to the failure of the cylinder 25 during the dust reduction process, resulting in poor dust reduction effect. A through hole 276 is opened inside the connecting ring 275, and the through hole 276 is set to be trapezoidal. The inner wall of the through hole 276 is clamped with a spring plate 277, and the middle part of the spring plate 277 is fixedly connected with a round rod 278. One end of the rod 278 away from the spring plate 277 is fixedly connected to a semicircular plate 279, and the side of the fixed ring 271 close to the connecting ring 275 is fixedly connected to a limiting block 272. There are multiple limiting blocks 272, and the multiple limiting blocks 272 are evenly distributed around the rotating shaft 28, and the semicircular plate 279 is located in the middle of two adjacent limiting blocks 272. The outer side of the fixed ring 271 is fixedly connected to a connecting rod 273, and both ends of the connecting rod 273 are fixedly connected to the fixed ring 271 and the connecting ring 275.

[0033] The second embodiment is based on the first embodiment. Figures 6 to 9As shown, the dust reduction component 3 includes a cylinder 31, the outer side of the cylinder 31 is rotatably connected to the rotating shaft 28, the end of the cylinder 31 close to the cylinder 25 is fixedly connected to the adjusting component 32, the end of the cylinder 31 away from the adjusting component 32 is fixedly connected to the filter plate 33, the outer top of the cylinder 31 is fixedly connected to the motor 34, the output end of the motor 34 is fixedly connected to the transmission member 35, the end of the transmission member 35 away from the motor 34 is fixedly connected to the fan 36, the motor 34 is connected to an external power supply to work, the motor 34 drives the fan 36 to rotate through the transmission member 35, at this time the high-speed airflow generated by the fan 36 further blows and diffuses the droplets sprayed by the spray component 37, so that it can be evenly distributed over a larger range, the transmission member 35 passes through the cylinder 31 and extends to the inside of the cylinder 31, the fan 36 is located inside the cylinder 31, the inner wall of the cylinder 31 is fixedly connected to the spray component 37, and the spray component 37 is located between the fan 36 and the adjusting component 32.

[0034] The spray assembly 37 includes a water pipe 371, which penetrates the cylinder 31 and extends to the inside. One end of the water pipe 371 is fixedly connected to a ring 372, which is located inside the cylinder 31 and is fixedly connected to the inner wall of the cylinder 31. The outer side of the ring 372 is fixedly connected to a shell 373, which is arranged in a stepped shape. The outer side of the shell 373 away from the ring 372 is provided with a discharge port 374. There are multiple discharge ports 374, which are evenly distributed on the outer side of the shell 373. The top of the shell 373 is fixedly connected to the outer side of the shell 373. The housing 379 is fixedly connected to the nozzle 373. When the speed of the motor 34 increases, the speed of the fan 36 increases, so that the flow rate of the airflow increases. The airflow drives the flow of gas near the discharge port 374 on the housing 373. The fast-flowing airflow generates a shear force on the liquid or particles sprayed from the nozzle. This shear force can make the liquid or particles more dispersed during the spraying process and reduce the possibility of their agglomeration, thereby improving the efficiency and rate of spraying. The faster the airflow speed, the lower the pressure will be. According to Bernoulli's principle, the faster the fluid speed, the lower the pressure will be. When the pressure is reduced, the water flow rate inside the shell 373 is faster, the force of the fluid on the positioning block 377 increases, and the positioning block 377 slides downward on the outside of the rotating shaft 375, so that the gap between the limiting ring 3711 and the positioning block 377 becomes smaller, so that the water pressure becomes larger, the droplets become smaller, and the dust reduction effect is improved. The inside of the shell 373 is fixedly connected to the limiting ring 3711, and the positioning block 377 is arranged inside the limiting ring 3711. The outside of the positioning block 377 is fixedly connected to the elastic plate 378, and the elastic plate 378 is away from the end of the positioning block 377. It is fixedly connected to the shell 379, and the middle part of the positioning block 377 is slidably connected with a rotating shaft 375. When water flows, the rotating plate 376 is driven to rotate under the action of the flow of the fluid, and the rotating plate 376 drives the rotating shaft 375 to rotate, so that the rotating shaft 375 drives the rotating plate 3710 to rotate, and guides the flow direction of water to avoid the inlet of the shell 379 from being subjected to force, thereby reducing the service life of the shell 379. The rotating plate 376 is fixedly connected to the outer side of the rotating shaft 375 near the discharge port 374, and the rotating plate 3710 is fixedly connected to the outer side of the rotating shaft 375 near the shell 379.

[0035] The third embodiment is based on the first and second embodiments. Fig.10As shown, the adjustment component 32 includes a straight cylinder 321, and the inner wall of the straight cylinder 321 away from the cylinder 31 is provided with a slide groove 322, and the interior of the slide groove 322 is slidably connected to an extension cylinder 324, and the extension cylinder 324 is fixedly connected to the outer side of the straight cylinder 321, and the extension cylinder 324 is close to The extension block 323 is connected, and the extension cylinder 324 can be pushed in a direction away from the straight cylinder 321, so that a new hollow frustum cylinder is formed inside the extension cylinder 324, and the diameter of the frustum cylinder is further reduced. Therefore, when the airflow passes through the hollow frustum cylinder with a smaller diameter formed by the extension cylinder 324, the pressure of the airflow is greater, and the airflow can drive the fog group to fly a farther distance, so that the range of the dust reduction component 3 can be increased. Without increasing the power of the fan, the range of the dust reduction component 3 is increased, and the adjustment method is more economical and practical. At the same time, the length of the straight cylinder 321 is extended by setting the extension cylinder 324, so that the output The wind pressure is not dispersed, which is suitable for narrowing the range and precise dust reduction. The end of the extension block 323 away from the extension tube 324 is fixedly connected to the inner wall of the straight tube 321. The straight tube 321 is set to a cone. The inner wall of the straight tube 321 is fixedly connected with a spiral plate 325. The airflow drives the sprayed droplets to pass through the spiral plate 325 and then spray out from the straight tube 321. By setting the spiral plate 325 and the limiting rod 326, the gas can be evenly mixed with the sprayed droplets. At the same time, the gas drives the droplets to collide with the limiting rod 326 to generate a large number of bubbles. The bubbles greatly increase the overall surface area of ​​the water mist, increase the contact area with the dust, and increase the viscosity of the bubbles, thereby improving the overall dust reduction efficiency. The middle part of the spiral plate 325 is slidably connected to the limiting rod 326, and the limiting rod 326 and the end away from the spiral plate 325 are fixedly connected to the inner wall of the extension tube 324.

[0036] When in use, the motor 22 is connected to an external power source, and the motor 22 drives the turntable 23 to rotate. The turntable 23 drives the dust reduction component 3 to rotate 360 ​​degrees through the connecting plate 24. At the same time, the cylinder 25 works to push the dust reduction component 3 to rotate around the bracket 26, thereby adjusting the inclination direction of the dust reduction component 3, so that the spray direction and angle of the water mist can be adjusted efficiently.

[0037] The dust removal component 3 is driven to rotate by the cylinder 25, and the dust removal component 3 drives the outer rotating shaft 28 to rotate on the bracket 26. At this time, the rotating shaft 28 drives the rotating rod 274 to rotate, and the rotating rod 274 drives the connecting ring 275 to rotate. At this time, the round rod 278 inside the connecting ring 275 drives the semicircular plate 279 to rotate inside the fixed ring 271. When the semicircular plate 279 contacts and squeezes the limit block 272, the elastic performance of the spring plate 277 is used to make the semicircular plate 279 pass through the limit block 272 smoothly, so as to adjust the inclination angle of the dust removal component, which can improve the water spray coverage and purification effect, and can more comprehensively cover the area that needs to be purified, reduce the water spray dead angle or loopholes, and after adjusting the inclination angle, the semicircular plate 279 is located in the middle of the two adjacent limit blocks 272. The semicircular plate 279 is limited by the two limit blocks 272 to prevent the dust removal component 3 from rotating at an inclination angle due to a failure of the cylinder 25 during the dust removal process.

[0038] The motor 34 is connected to an external power source to work, and the motor 34 drives the fan 36 to rotate through the transmission member 35. At this time, the high-speed airflow generated by the fan 36 further disperses and diffuses the droplets sprayed by the spray assembly 37, so that the droplets can be evenly distributed in a larger range.

[0039] When the speed of the motor 34 increases, the speed of the fan 36 increases, so that the flow rate of the airflow increases. The airflow drives the flow of gas near the discharge port 374 on the shell 373. The fast-flowing airflow generates a shear force on the liquid or particles sprayed from the nozzle. This shear force can make the liquid or particles more dispersed during the spraying process and reduce the possibility of their agglomeration, thereby improving the efficiency and rate of spraying. In addition, a faster airflow velocity will form a local low-pressure area around the discharge port 374. According to Bernoulli's principle, when the fluid velocity increases, the pressure will decrease. At this time, the water flow rate inside the shell 373 becomes faster, and the positioning block 377 is subjected to an increased force from the fluid. The positioning block 377 slides downward on the outside of the rotating shaft 375, so that the gap between the limit ring 3711 and the positioning block 377 becomes smaller, thereby increasing the water pressure, reducing the droplets, and improving the dust reduction effect.
