Description

Technical Field

[0001] This application generally relates to the field of mining equipment technology, and in particular to dust suppression devices for mining. Background Technology

[0002] Open-pit mining, also known as open-face mining, is the process of removing the overburden from a ore body to obtain the desired minerals; it involves extracting useful minerals from an open-faced mining site. During open-pit mining, processes such as excavation, blasting, and loading generate large amounts of dust. This dust not only severely impacts air quality in the mining area but also spreads with the wind to surrounding areas, damaging the ecological environment. Current technologies generally employ dust suppression devices to reduce the concentration of dust in the air, improve air quality in and around the mining area, and protect the ecological environment.

[0003] However, current dust suppression devices generally rely on spraying water mist at fixed heights and directions. Since the height and direction of dust dispersion can vary due to wind and operating conditions, the water mist sprayed by the dust suppression device cannot accurately cover the dust-prone areas. This requires frequent manual movement of the device or adjustment of the spray angle. Furthermore, the fixed spray range and angle can lead to excessive concentration of water mist in some areas, while other areas fail to achieve effective dust suppression. This results in a waste of water resources and fails to achieve reliable dust suppression. Summary of the Invention

Hardware diagrams should not be fixed and need to be adjusted according to the actual situation of the solution, including the GPU, etc. Detailed Implementation The present application / disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application / disclosure and are not intended to limit the scope of the present application / disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present application / disclosure are shown in the accompanying drawings, not the entire structure.

[0019] like Figures 1 to 8As shown, this application provides a dust suppression device for mining, including a water tank 1, a first adjusting mechanism 2, a second adjusting mechanism 3, a spray dust suppression mechanism 4, and a control device 10. The first adjusting mechanism 2 is disposed on the water tank 1, and the second adjusting mechanism 3 is disposed on the first adjusting mechanism 2. The first adjusting mechanism 2 can drive the second adjusting mechanism 3 to move to adjust the height of the second adjusting mechanism 3. The spray dust suppression mechanism 4 is disposed on the second adjusting mechanism 3, and the second adjusting mechanism 3 can drive the spray dust suppression mechanism 4 to move to adjust the spraying direction of the spray dust suppression mechanism 4. The inlet of the spray dust suppression mechanism 4 is connected to the water tank 1 through a pipeline. The control device 10 is electrically connected to the first adjusting mechanism 2, the second adjusting mechanism 3, and the spray dust suppression mechanism 4. The first adjustment mechanism 2 and the second adjustment mechanism 3 can adjust the height and angle of the spray dust suppression mechanism 4, allowing the sprayed water mist to be flexibly adjusted according to the actual site conditions such as the height and direction of dust dispersion. This optimizes the spray range and angle of the water mist, ensuring that the water mist can accurately cover dust sources at different heights and directions. This overcomes the problem of frequent manual movement or adjustment required in existing technologies, and also avoids excessive concentration of water mist in local areas, improving water resource utilization efficiency and reducing waste. At the same time, it can significantly improve the dust suppression effect, ensuring that the water mist can accurately cover dust sources at different heights and directions, avoiding dust suppression blind spots, achieving more comprehensive dust suppression coverage, and improving the applicability of dust suppression devices for mining. This provides a more efficient and convenient dust suppression solution for open-pit mining and other operations.

[0020] When adjusting the dust suppression device used in mining, the user can control the first adjustment mechanism 2, the second adjustment mechanism 3, and the spray dust suppression mechanism 4 through the control device 10 according to needs or directly based on the relevant data of dust rising (such as the area and height of dust rising). The first adjustment mechanism 2 simultaneously drives the second adjustment mechanism 3 and the spray dust suppression mechanism 4 to move in the height direction, thereby realizing the height adjustment of the spray dust suppression mechanism 4. The second adjustment mechanism 3 can drive the spray dust suppression mechanism 4 to rotate, thereby adjusting the spraying direction of the spray dust suppression mechanism 4. The cooperation of the first adjustment mechanism 2 and the second adjustment mechanism 3 can realize the adjustment of the spraying height and spraying angle of the spray dust suppression mechanism 4. Furthermore, the first adjustment mechanism 2 and the second adjustment mechanism 3 can be adjusted in real time during the spraying process of the spray dust suppression mechanism 4, further improving the dust suppression effect and avoiding dust suppression blind spots.

[0021] In one embodiment, the first adjustment mechanism 2 includes a lead screw 21, a servo motor 20, and an adjustment sleeve 23. The lead screw 21 is rotatably mounted on the water tank 1. The servo motor 20 is connected to the lead screw 21 and can drive the lead screw 21 to rotate. The adjustment sleeve 23 is sleeved on the lead screw 21 and is threadedly engaged with the lead screw 21. The lead screw 21 can drive the adjustment sleeve 23 to move up and down by rotating. The second adjustment mechanism 3 is mounted on the adjustment sleeve 23. The servo motor 20 drives the lead screw 21 to rotate. At the same time, the threaded engagement between the adjustment sleeve 23 and the lead screw 21 can adjust the rotation of the lead screw 21 into linear movement of the adjustment sleeve 23. The linear movement of the adjustment sleeve 23 can drive the second adjustment mechanism 3 to move, thereby driving the spray dust suppression mechanism 4 to move.

[0022] Specifically, a nut 24 is provided at the bottom of the adjusting sleeve 23. The nut 24 is threadedly engaged with the lead screw 21, and the nut 24 is fixedly set with the adjusting sleeve 23. When the lead screw 21 rotates, the nut 24 is forced to move along the axis of the lead screw 21 due to the threaded engagement with the lead screw 21. This allows the adjusting sleeve 23 to move along the axis of the lead screw 21. At this time, the lead screw 21 is set in the vertical direction, which enables the adjusting sleeve 23 to move up and down, thereby realizing the adjustment of the second adjusting mechanism 3 in the height direction.

[0023] The lead screw 21 is located on the side of the water tank 1. Only the adjusting sleeve 23 can protrude upward from the water tank 1 as needed. When the height of the dust suppression spraying mechanism 4 does not need to be adjusted, the lead screw 21 and the adjusting sleeve 23 can both be located on the side of the water tank 1, which reduces the height of the dust suppression device for mining, thereby effectively reducing the volume of the dust suppression device for mining and facilitating the transportation and storage of the dust suppression device for mining.

[0024] Furthermore, a mounting base 17 is provided on the water tank 1. The lower end of the lead screw 21 is rotatably mounted on the mounting base 17. The servo motor 20 is mounted on the mounting base 17, and the output shaft of the servo motor 20 is coaxial with the lead screw 21. The mounting base 17 limits the lower end of the lead screw 21, ensuring the reliable position of the lead screw 21 on the water tank 1, and also providing a mounting position for the servo motor 20. A first rotating rod 22 without threads is provided at the lower end of the lead screw 21. The mounting base 17 has a mounting hole, and a first bearing 19 is disposed in the mounting hole. The first rotating rod 22 is mounted on the mounting base 17 through the first bearing 19, allowing the lead screw 21 to be reliably mounted on the mounting base 17. The first rotating rod 22 is fixedly connected to the output end of the servo motor 20, realizing the connection between the lead screw 21 and the servo motor 20. The servo motor 20 is located below the mounting base 17. At this time, the lower end of the first rotating rod 22 can be directly connected to the servo motor 20, while the upper end can be directly connected to the lead screw 21. This reduces the structural complexity of the first adjustment mechanism 2 and allows the servo motor 20 to be stored below the mounting base 17, thereby reducing the size of the dust suppression device in the width direction and effectively reducing the volume of the dust suppression device, which facilitates the transportation and storage of the dust suppression device.

[0025] To ensure reliable movement of the adjusting sleeve 23, a guide block 26 is provided on the water tank 1. The guide block 26 is located above the mounting base 17, and the adjusting sleeve 23 is located between the mounting base 17 and the guide block 26. A through hole 27 is provided on the guide block 26, through which the adjusting sleeve 23 protrudes from the guide block 26. The second adjusting mechanism 3 is located at the end of the adjusting sleeve 23 protruding from the guide block 26. The guide block 26 restricts the vertical movement of the adjusting sleeve 23, ensuring the reliability of its movement direction. Preferably, a limiting guide groove 25 is provided on the side wall of the adjusting sleeve 23, and a limiting guide block 28 is provided on the side wall of the through hole 27. The limiting guide groove 25 can guide and cooperate with the limiting guide block 28, preventing the adjusting sleeve 23 from rotating with the lead screw 21, forcing the adjusting sleeve 23 to move only in the vertical direction, thus ensuring the reliability of the adjusting sleeve 23's movement.

[0026] The second adjustment mechanism 3 includes a fixed plate 29, a rotary motor 32, a support rod 34, and a transmission mechanism. The fixed plate 29 is fixedly mounted on the first adjustment mechanism 2, the rotary motor 32 is fixedly mounted on the fixed plate 29, and the support rod 34 is rotatably mounted on the fixed plate 29. The rotary motor 32 is connected to the support rod 34 through the transmission mechanism, and the dust suppression spraying mechanism 4 is mounted on the support rod 34. By using the rotary motor 32 to drive the support rod 34 to rotate through the transmission mechanism, the spraying direction of the dust suppression spraying mechanism 4 on the support rod 34 is adjusted, thereby achieving adjustment of the spraying angle.

[0027] Specifically, the fixing plate 29 is fixedly installed on the top of the adjusting sleeve 23, so that the movement of the adjusting sleeve 23 can directly drive the fixing plate 29 to move, which in turn can drive the rotary motor 32, the support rod 34 and the spray dust suppression mechanism 4 to move synchronously, ensuring that the first adjusting mechanism 2 can reliably drive the spray dust suppression mechanism 4 to adjust its height.

[0028] The fixed plate 29 is provided with a mounting groove 30, and the end of the support rod 34 is set in the mounting groove 30 through the second bearing 31, so that the support rod 34 can rotate relative to the fixed plate 29, thus ensuring the positional reliability of the support rod 34 and the rotational reliability of the support rod 34.

[0029] Optionally, the transmission mechanism includes a driving gear 33 and a driven gear 35. The driving gear 33 is mounted on the output shaft of the rotary motor 32, and the driven gear 35 is mounted on the support rod 34. The driving gear 33 and the driven gear 35 mesh with each other to drive the rotary motor 32 to rotate the support rod 34. The output shaft of the rotary motor 32 drives the driving gear 33 to rotate, and the meshing of the driving gear 33 and the driven gear 35 drives the driven gear 35 to rotate. The driven gear 35 then drives the support rod 34 to rotate, thereby realizing the rotation of the spray dust suppression mechanism 4 mounted on the support rod 34.

[0030] Furthermore, the second adjusting mechanism 3 also includes a second rotating rod 36, a second bearing 31 disposed on the second rotating rod 36, and a driven gear 35 disposed between the second rotating rod 36 and the support rod 34, facilitating the installation of the support rod 34, the driven gear 35, and the second rotating rod 36, and also enabling... To avoid structural interference between the dust suppression spraying mechanism 4 and the water tank 1, the support rod 34 is L-shaped and includes a vertical portion 341 and a horizontal portion 342. The lower end of the vertical portion 341 is rotatably mounted on the fixed plate 29, and the first end of the horizontal portion 342 is connected to the upper end of the vertical portion 341. The driven gear 35 is mounted on the vertical portion 341, and the dust suppression spraying mechanism 4 is mounted on the second end of the horizontal portion 342. The vertical portion 341 creates a certain height difference between the dust suppression spraying mechanism 4 and the water tank 1, which avoids interference between the dust suppression spraying mechanism 4 and the water tank 1 during rotation and provides a position for the installation of the driven gear 35. The horizontal portion 342 creates a certain horizontal distance between the dust suppression spraying mechanism 4 and the water tank 1, thereby preventing interference between the dust suppression spraying mechanism 4 and other components and further ensuring the structural reliability of the dust suppression spraying mechanism 4. Figure 1 and 2As shown, a water pump is installed at the top of the water tank 1. The height of the vertical part 341 is greater than the height of the water pump, so that the dust suppression spraying mechanism 4 will not interfere with the water pump during rotation. The horizontal part 342 further increases the horizontal distance between the dust suppression spraying mechanism 4 and the water pump, further avoiding interference between the dust suppression spraying mechanism 4 and the water pump during rotation, thereby effectively improving the structural reliability of the dust suppression device for mining.

[0031] In one embodiment, the dust suppression spraying mechanism 4 includes a water pump 12, a spray pipe 15, and atomizing nozzles 16. The water pump 12 is mounted on a water tank 1, and the spray pipe 15 is mounted on a second adjusting mechanism 3. The spray pipe 15 is connected to the water tank 1 via the water pump 12 and a pipeline. The atomizing nozzles 16 are mounted on the spray pipe 15 and are connected to the spray pipe 15. The water pump 12 pumps water from the water tank 1 into the spray pipe 15, and distributes the water to all the atomizing nozzles 16. Finally, the water is sprayed through the atomizing nozzles 16 to achieve the purpose of dust suppression. The spray pipe 15 is mounted on the second adjusting mechanism 3, which can drive the spray pipe 15 to rotate, thereby causing the atomizing nozzles 16 to spray in different directions. The atomizing nozzles 16 are at least two in number, and all atomizing nozzles 16 are arranged side by side along the length of the spray pipe 15, which effectively increases the spray range of the dust suppression mechanism 4 and improves the dust suppression effect.

[0032] like Figure 1 and Figure 2 As shown, the water pump 12 is installed on the top surface of the water tank 1, and the bottom of the water tank 1 is provided with a water outlet 6. The water pump 12 is connected to the water outlet 6 through the water suction pipe 13, so that the water pump 12 can pump water from the water tank 1 to the spray pipe 15 from the water outlet 6. A valve 7 is also provided between the water pump 12 and the water outlet 6, and the control device 10 can control the pump body and the valve 7.

[0033] Meanwhile, a fixing ring 37 is provided on the free end of the transverse portion 342, and the spray pipe 15 passes through the fixing ring 37, thereby realizing the fixed connection between the spray pipe 15 and the transverse portion 342.

[0034] Since the dust suppression spraying mechanism 4 needs to move with the adjustment of the first adjustment mechanism 2 and the second adjustment mechanism 3, the pipeline connected between the water pump 12 and the spray pipe 15 needs to deform with the movement of the dust suppression spraying mechanism 4. Therefore, the pipeline 14 can be selected as a flexible hose or a corrugated pipe.

[0035] A water inlet 8 is provided on the top surface of the water tank 1, and a level gauge 9 is provided on the water tank 1. Water from the outside is injected into the water tank 1 through the water inlet 8, and the water level in the water tank 1 is detected in real time by the level gauge 9. When the water level in the water tank 1 reaches the preset value, the control device 10 can receive the signal from the level gauge 9 and stop adding water, or notify the staff to determine whether to stop adding water.

[0036] To further facilitate the use of the dust suppression device in mining, the device also includes a vehicle body, with a water tank 1 mounted on it. The vehicle body is configured to move the water tank 1 across the ground. By using the vehicle body to move the water tank 1, the first adjustment mechanism 2, the second adjustment mechanism 3, and the spray dust suppression mechanism 4, it can quickly reach the dust-generating area for dust suppression without manual intervention. The vehicle body can be towed by an external vehicle or can be powered by its own motor.

[0037] To further facilitate use by staff, the control device 10 is detachably mounted on the water tank 1 and electrically connected to the vehicle body. That is, the control device 10 can be removed from the water tank 1 and used as a remote control device. Simultaneously, the remote control device can also control the vehicle body, allowing the mining dust suppression device of this application to be moved to a predetermined area without manual handling.

[0038] Combination Figures 1 to 8 The dust suppression method of the mining dust suppression device in this application is as follows: First, water is added to the water tank 1 through the water inlet 8, and the water level in the water tank 1 is judged by the level gauge 9. The control device 10 can obtain the parameters of the level gauge 9 to directly control the water supply to stop, or notify the staff to judge whether the water supply needs to be stopped. When the water level in the water tank 1 has reached the preset value, the staff operates the vehicle to move the entire equipment to the dusty area where dust suppression is required. Second, the height of the atomizing nozzle 16 is adjusted according to the height of the dust. The control device 10 controls the servo motor 20 to work. The servo motor 20 drives the lead screw 21 to rotate. The nut 24 in the adjusting sleeve is threaded with the lead screw 21. At the same time, the limiting guide groove 25 on the adjusting sleeve and the limiting guide block 28 on the guide block 26 cooperate to force the adjusting sleeve to only move up and down. The height of the second adjusting mechanism 3 at the upper end of the adjusting sleeve and the spray dust suppression mechanism 4 are adjusted until the height of the atomizing nozzle 16 is adjusted to the required height. Third, the spraying direction of the atomizing nozzle 16 is adjusted according to the location of the dust area. The control device 10 controls the rotating motor to work. The rotating motor drives the drive gear 33 to rotate. The drive gear 33 drives the driven gear 35 to rotate through meshing. The driven gear 35 drives the second rotating rod 36 and the support rod 34 to rotate at the same time, thereby realizing the orientation adjustment of the dust suppression spraying mechanism 4, and thus achieving the purpose of adjusting the spraying angle of the atomizing nozzle 16. Finally, valve 7 at outlet 6 on water tank 1 is opened, and control device 10 controls water pump 12 to start. Water pump 12 sends water from water tank 1 to water pump 12 via water pipe 13, and then through hose to spray pipe 15. The water entering spray pipe 15 reaches all atomizing nozzles 16 and is finally sprayed out by atomizing nozzles 16. The atomized water can be sprayed above the dust-generating area, thus spraying dust to suppress dust generated during open-pit mining. During the dust suppression process, when level gauge 9 detects that the water level in water tank 1 has dropped to the preset minimum value, level gauge 9 transmits an electrical signal to control device 10. Control device 10 will activate alarm 11 on the top of water tank 1. Alarm 11 will sound an alarm to remind workers to replenish water in water tank 1 in time to prevent insufficient water in water tank 1 from affecting the dust suppression of open-pit mining dust.

[0039] Meanwhile, during the dust suppression spraying process, the control device 10 can control the first adjustment mechanism 2 and the second adjustment mechanism 3 in real time to optimize the spray range and angle of the water mist, improve the utilization efficiency of water resources, and reduce waste.
