Description

Technical Field

[0001] This invention belongs to the field of dust suppression and removal technology, and in particular relates to a water mist dust removal device for sand and gravel production and processing. Background Technology

[0002] As a core raw material supplier for infrastructure construction, the sand and gravel industry generates a large amount of dust during its production and processing (including raw material crushing, screening, transportation, and finished product loading). These dust particles, mainly PM10 and PM2.5, not only diffuse within the factory area but also drift into the surrounding atmosphere. Long-term exposure to high dust levels can easily lead to occupational diseases such as pneumoconiosis among workers. Therefore, dust removal is necessary during the production and processing of sand and gravel. For example, a dust removal device for sand and gravel production in hydropower stations is disclosed in patent publication number CN211159072U.

[0003] After the sand and gravel production and processing are completed, they need to be loaded into transport vehicles by loaders and then transported to designated locations. When the loaders are loading, the sand and gravel fall from a height into the truck bed, and the impact generates a large amount of dust, which needs to be treated with a water mist dust removal device. However, the impact of the falling material during the loading stage is strong, and the dust will burst out in a large amount at an instant. The dust removal device needs to spray a sufficient amount of water mist to quickly reduce the dust. If too much water mist is sprayed, it will not only cause the finished sand and gravel to have an excessive moisture content, causing the material to stick to the truck bed and making it difficult to unload, but it will also increase the transportation weight due to the damp material, thereby increasing the transportation cost.

[0004] Therefore, a water mist dust removal device for sand and gravel production and processing is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a water mist dust removal device for sand and gravel production and processing.

[0019] 2. Through the set spray components, the spray direction of the spray components can be adjusted according to the outdoor wind force and direction during the dust suppression process, so that the dust generation area is within the water mist spray range, thereby reducing the impact of strong wind on the water mist dust removal effect.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] like Figures 1-7As shown, a water mist dust removal device for sand and gravel production and processing includes a base plate 1. A controller 2 is fixedly connected to the upper side wall of the base plate 1. Two support frames 3 are symmetrically fixedly connected to the upper side wall of the base plate 1. Reinforcing rods 33 are fixedly connected to the inner walls of both support frames 3. The reinforcing rods 33 and the support frames 3 are both made of stainless steel. Both support frames 3 have an inverted L-shaped structure. Vertical rods 4 facing downwards are fixedly connected to the upper walls of both support frames 3. Support plates 5 are fixedly connected to the lower ends of both vertical rods 4. A spray assembly 6 is provided between the two support plates 5. The spray assembly 6 includes a frame tube 61. The frame tube 61 has a square structure. A grid tube frame 62 is connected to the inner wall of the frame tube 61. Multiple mist sprayers are fixedly connected to the lower side wall of the grid tube frame 62. The spray nozzle 7 has adjusting rods 8 rotatably connected to the side walls of the two support plates 5 on opposite sides. An adjusting motor 9 is fixedly connected to the side wall of the right support plate 5 away from the adjusting rod 8. The output end of the adjusting motor 9 is fixedly connected to the right adjusting rod 8. A water storage tank 10 is fixedly connected to the upper side wall of the base plate 1. A water pump 11 is fixedly connected to the upper side wall of the water storage tank 10. A water delivery hose 12 is fixedly connected to the output end of the water pump 11. The upper end of the water delivery hose 12 is connected to the frame pipe 61. During the dust suppression process, the spray direction of the spray assembly 6 can be adjusted according to the outdoor wind force and direction, ensuring that the dust-generating area is always within the water mist spray range, thereby reducing the impact of strong winds on the water mist dust suppression effect. It also includes:

[0031] A flow-guiding and shielding assembly 13 is positioned below the spray assembly 6 to prevent a large amount of water mist from spraying onto the sand and gravel surface. The flow-guiding and shielding assembly 13 includes two first lead screw linear modules 131, each fixedly connected to the lower sidewall of one of the two support plates 5. A second lead screw linear module 132 is fixedly connected to the moving end of each of the two first lead screw linear modules 131. An adjusting plate 14 is fixedly connected to the moving end of each of the two second lead screw linear modules 132. A flow-guiding hood 15 is provided between the two adjusting plates 14. A receiving seat 16 is fixedly connected to the right sidewall of the flow-guiding hood 15. The sidewalls of the receiving seat 16 and the flow-guiding hood 15 opposite to each other are fixedly connected to... The crossbars 17 are connected to two adjusting plates 14 at opposite ends. Multiple spray cylinders 18 are fixedly inserted into the lower side wall of the guide shroud 15. The spray cylinders 18 are cylindrical. The guide shroud 15 is connected to the sewage treatment device 19. When the loader loads sand and gravel into the transport vehicle, it can block the impact airflow generated when the sand and gravel collide with the truck bed to a certain extent, weaken the lifting force of the airflow on the dust, reduce the impact height of the dust, and collect some sewage during the spraying of a large amount of water mist by the dust removal device. This avoids the problem of excessive moisture content of finished sand and gravel in the truck bed, which causes difficulty in unloading and increases transportation costs due to damp materials.

[0032] The identification component 23 is set on the surface of the flow guide shield component 13 and can adjust the position of the flow guide shield component 13 according to the parking position of the transport vehicle. The identification component 23 includes a third lead screw linear module 231 fixedly connected to the side wall of the flow guide 15. An electric push rod 232 is fixedly connected to the moving end of the third lead screw linear module 231. A moving plate 24 is fixedly connected to the moving end of the electric push rod 232. A drive motor 25 is fixedly connected to the side wall of the moving plate 24. The output end of the drive motor 25 passes through the moving plate 24 and is fixedly connected to a mounting base 26. Multiple vision sensors 27 are fixedly connected to the lower side wall of the mounting base 26.

[0033] The protective component 28 is disposed on the side wall of the flow-guiding and shielding component 13. The protective component 28 includes multiple protective grooves 281 formed on the lower side wall of the storage base 16. The groove walls of the multiple protective grooves 281 are connected to annular airbags 282 via brackets. The same air supply pipe 29 is inserted into the multiple protective grooves 281. An air pump 30 is fixedly connected to the side wall of the storage base 16. The air outlet of the air pump 30 is connected to the air supply pipe 29. A vertical pipe 31 is fixedly connected between the air supply pipe 29 and the multiple annular airbags 282. One end of the air supply pipe 29 extends out of the storage base 16. A control valve 32 is provided in the air supply pipe 29 for identifying the protection of the component 23.

[0034] The wastewater treatment device 19 includes a wastewater tank 191 fixedly connected to the upper side wall of the base plate 1. The wastewater tank 191 and the guide shroud 15 are fixedly connected by the same return hose 192. The inner wall of the wastewater tank 191 is fixedly connected to two inclined filter screens 20, with the mesh size of the upper filter screen 20 being larger than that of the lower filter screen 20. The side wall of the wastewater tank 191 has two sewage outlets 21. The side wall of the wastewater tank 191 near the water storage tank 10 is fixedly connected to a wastewater pump 22. The outlet of the wastewater pump 22 is connected to the water storage tank 10. After collecting the sprayed water mist, the wastewater can flow into the wastewater tank 191 for filtration treatment, and the filtered water can be transported back to the spray assembly 6 for spraying. This allows for the reuse of water resources and reduces water waste.

[0035] The operating principle of this invention is explained as follows: The driver parks the transport vehicle near the base plate 1, positioning it directly below the spray assembly 6. Then, the operator sends an electrical signal to the controller 2 via an external switch. Upon receiving this signal, the controller 2 controls the electric push rod 232 and the control valve 32. The control valve 32 opens for two seconds, causing the gas inside the annular airbag 282 to be discharged through the air delivery pipe 29. The electric push rod 232 then moves the drive motor 25, mounting base 26, and vision sensor 27 downwards to a set position via the moving plate 24, causing the vision sensor 27 to be withdrawn from the protective groove 281. Next, the controller 2 controls the drive motor 25 to operate, which in turn moves the mounting base... The 26 and vision sensor 27 are rotated 180 degrees together, so that the vision sensor 27 is placed downwards. Then, the controller 2 controls the third lead screw linear module 231 to work. The third lead screw linear module 231 drives the vision sensor 27 to move back and forth once. The controller 2 uses the vision sensor 27 to detect the position of the carriage. After the vision sensor 27 finishes detection, the controller 2 controls the vision sensor 27 to be reinserted into the protective groove 281 and controls the air pump 30 to work for three seconds. The air pump 30 will deliver external gas through the air supply pipe 29 and the vertical pipe 31 to multiple annular airbags 282, causing the annular airbags 282 to inflate and fill the gap between the vision sensor 27 and the protective groove 281, preventing the entry of moisture and dust.

[0036] During the storage of the vision sensor 27, the vision sensor 27 acquires images of the truck bed and sends the acquired image signals to the controller 27. The controller 27 processes the images, identifies the boundaries of the truck bed, and calculates the movement coordinates of the deflector 15 based on the position of the truck bed boundaries. Based on this coordinate information, the controller controls the first lead screw linear module 131 and the second lead screw linear module 132 to operate. The first lead screw linear module 131 controls the deflector 15 to move left and right to the appropriate position, and the second lead screw linear module 132 controls the deflector 15 to move forward and backward to the appropriate position, so that the deflector 15 is directly above the truck bed. When the loader loads stones into the truck bed, the controller 2 controls the water pump 11 to operate. The water pump 11 delivers water from the water storage tank 10 to the frame pipe 61 and the grid pipe frame 62, and sprays it out through multiple atomizing nozzles 7. The area of ​​the grid pipe frame 62 and the frame pipe 61 is larger than the area of ​​the truck bed and the deflector 15. Therefore, the impact of the stones on the truck bed generates... The dust is completely within the water mist spray range. Since the deflector 15 is located directly above the truck bed, it can block the impact airflow generated when the sand and gravel collide with the truck bed to a certain extent, weakening the lifting force of the airflow on the dust and reducing the impact height of the dust. Some dust will pass through the spray pipe 18 on the surface of the deflector 15 and combine with the water mist, and fall onto the surface of the deflector 15. Some water mist will pass through the spray pipe 18 and fall onto the surface of the sand and gravel inside the truck bed. Since the deflector 15 is located directly above the truck bed, a large amount of water mist will be collected by the deflector 15, thereby avoiding the problem of excessive moisture content of the finished sand and gravel inside the truck bed, which would cause difficulties in unloading and increase transportation costs due to damp materials. The sewage that falls into the deflector 15 will be transported to the sewage tank 191 through the return hose 192. The sewage will be filtered by two layers of filter screen 20 before falling into the sewage tank 191. Impurities will be discharged through the drain outlet 21. The filtered sewage will be transported to the water storage tank 10 by the sewage pump 22 for storage, so that water resources can be reused.

[0037] When the controller 2 detects strong winds outdoors through the external wind force sensor and wind direction sensor, the controller 2 will control the regulating motor 9 and the regulating rod 8 to drive the spray assembly 6 to rotate at a certain angle, so that the dust generation area is within the water mist spray range, thereby reducing the impact of strong winds on the water mist dust removal effect to a certain extent.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
