Description

Technical Field

[0001] This utility model belongs to the field of mining engineering technology, and specifically relates to a three-dimensional dust suppression device for open-pit coal mine working faces. Background Technology

[0002] Spray dust suppression is a new type of industrial dust control technology. It uses high-pressure atomized water to form micron-sized droplets to capture suspended dust. It is mainly used for dust control in industrial settings such as mines, coal sheds, and foundries, as well as public spaces. This technology consists of a high-pressure pump, pipelines, nozzles, and an intelligent control system. It uses 50-70 kg of water pressure to convert water into 3-15 micron mist particles. Dust is settled through inertial collision and diffusion adsorption. Open-pit coal mines easily generate a large amount of dust during mining, blasting, transportation, and transfer processes. This type of dust has a wide diffusion range and high concentration, which not only threatens the health of workers but may also accelerate equipment wear and affect the surrounding ecological environment. The three-dimensional dust suppression device for open-pit coal mines is based on a pipeline spray system. By laying a continuous pipeline network at fixed dust-generating points and key operating areas, pressurized water is atomized through nozzles to form a spray. This can continuously cover and suppress dust in areas such as drilling rig operating areas, crushing stations, material transfer points, and transportation roads to control dust diffusion and improve the working environment.

[0003] However, traditional three-dimensional dust suppression devices for open-pit coal mine working faces are difficult to adapt to the diverse dust-generating locations and dust diffusion paths of the working face. Spray coverage is prone to deviation, and adjustments require additional tools, making operation cumbersome and difficult to adjust quickly according to on-site conditions. This results in insufficient targeting and adaptability of dust suppression coverage. At the same time, it is easy to create dust control blind spots, making it difficult to adapt to the dust suppression needs of open areas in open-pit coal mines. It is necessary to increase equipment deployment or rely on additional power to expand coverage, which is cumbersome and results in insufficient dust suppression efficiency and scene adaptability.

[0004] To address the problems mentioned above, a three-dimensional dust suppression device for open-pit coal mine working faces is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a three-dimensional dust suppression device for open-pit coal mine working faces, which has the advantages of adjusting the spray angle and expanding the coverage area.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a three-dimensional dust suppression device for open-pit coal mine working faces, comprising a branch pipe, a rotating shaft rotatably sleeved on the right side of the branch pipe surface, a connecting pipe fixedly sleeved on the right side of the inner side of the rotating shaft, a connecting block fixedly sleeved on the left side of the branch pipe surface, a support provided on the left side of the branch pipe, a slot opened on the right side of the support, and the right side of the inner wall of the slot rotatably sleeved with the right side of the surface of the connecting block, springs bolted to the left side of the bottom and top of the connecting block, a buckle fixedly connected to the end of the spring away from the connecting block, a slot opened on the left side of the inner wall of the slot, the inside of the top and bottom slots engaging with the surface of the buckle, a water outlet provided on the front of the branch pipe, and a rotating mechanism provided on the surface of the water outlet.

[0007] The above technical solution involves rotating the branch pipe, causing the connecting block to rotate within the slot of the bracket, which in turn causes the buckle compression spring to disengage from the slot. After adjusting to the target angle, the spring resets and pushes the buckle into the corresponding slot to achieve positioning. Simultaneously, the rotation of the shaft and the connecting pipe assists in adjusting the branch pipe angle and keeping the branch pipe stable. Finally, the spray output through the outlet covers the target area at the adjusted angle. The spray angle can be flexibly adjusted to adapt to different dust-generating locations and dust diffusion paths on the work surface, ensuring accurate spray coverage of the target area. No additional tools are required for operation, facilitating quick on-site adjustments and improving operational convenience. The operation is also convenient and can be quickly adjusted according to on-site conditions, effectively improving the targeting and adaptability of dust suppression coverage.

[0008] The present invention is further configured such that the rotating mechanism includes a rotating cylinder, the rotating cylinder is fixedly sleeved on the surface of the water outlet, a water outlet pipe is rotatably sleeved on the front end of the rotating cylinder surface, and nozzles are provided on both sides of the front of the water outlet pipe.

[0009] The above technical solution employs a rotating mechanism. Water flows through the outlet into the rotating drum, then into the outlet pipe and is sprayed out from the nozzles on both sides. The reaction force generated when the water is sprayed out drives the outlet pipe to rotate around the rotating drum, causing the nozzles to rotate with the outlet pipe, thus achieving a wide-area spray. The rotation expands the spray coverage area, making the spray more comprehensive and covering the working surface, reducing blind spots in dust control, and adapting to the dust suppression needs of open areas in open coal mines. Moreover, it requires no additional power, is easy to operate, and improves dust suppression efficiency and adaptability.

[0010] The present invention is further configured such that a telescopic rod is sleeved inside the spring.

[0011] The above technical solution uses a telescopic rod to limit the movement of the spring.

[0012] The present invention is further configured such that a sealing ring is embedded in the middle of the inner wall of the rotating shaft.

[0013] The above technical solution employs a sealing ring that, through an interference fit, provides a dynamic sealing function to prevent leakage.

[0014] The present invention is further configured such that a sealing ring II is fitted onto the rear end of the rotating drum surface.

[0015] The above technical solution employs a second sealing ring, which, through an interference fit, provides a dynamic sealing function to prevent leakage.

[0016] The present invention is further configured such that a telescopic sleeve is fitted onto the outside of the spring.

[0017] The above technical solution, by setting up a telescopic sleeve, can prevent external dust from entering the spring and affecting its functional performance.

[0018] The present invention is further configured such that the end of the connecting pipe away from the rotating shaft is connected to a main pipe.

[0019] The above technical solution involves setting up a main pipe, through which water enters the branch pipes via connecting pipes, and then is sprayed.

[0020] The present invention is further configured such that the back of the bracket is bolted to the wall.

[0021] The above technical solution allows for easy fixing of the bracket by setting up a wall surface.

[0022] In summary, this utility model has the following beneficial effects: 1. This utility model can flexibly adjust the spray angle to adapt to different dust-generating locations and dust diffusion paths on the working surface, ensuring accurate spray coverage of the target area. No additional tools are required for operation, making it easy to make quick adjustments on site and improving the convenience of operation. Moreover, it is easy to operate and can be quickly adjusted according to the on-site working conditions, effectively improving the targeting and adaptability of dust suppression coverage. 2. This utility model can expand the spray coverage area by rotating, so that the spray can cover the working surface more comprehensively, reduce the blind spots of dust control, adapt to the dust suppression needs of open areas of open coal mines, and does not require additional power drive, making it easy to operate and improving dust suppression efficiency and adaptability.

The branch pipe 1 has a slot 8, which is located at the top and bottom. The slot 8 is engaged with the surface of the buckle 7. The front of the branch pipe 1 has an outlet 9, and the surface of the outlet 9 has a rotating mechanism. When the branch pipe 1 is rotated, the connecting block 4 rotates in the slot 5 of the bracket 17, which drives the buckle 7 to compress the spring 6 and disengage from the slot 8. After adjusting to the target angle, the spring 6 returns to its original position and pushes the buckle 7 into the corresponding slot 8 to achieve positioning. At the same time, the rotation of the rotating shaft 2 and the connecting pipe 3 assists in the angle adjustment of the branch pipe 1 and keeps the branch pipe 1 stable. Finally, the spray output through the outlet 9 covers the target area at the adjusted angle.

[0027] refer to Figure 2 , Figure 3 The spring 6 has a telescopic rod 13 inside, which can limit the movement of the spring 6.

[0028] refer to Figure 2 The inner wall of the rotating shaft 2 is embedded with a sealing ring 14. By setting the sealing ring 14 and connecting it with an interference fit, it has a dynamic sealing function to prevent leakage. It is made of nitrile rubber.

[0029] refer to Figure 2 , Figure 3The spring 6 is fitted with a telescopic sleeve 16. By setting the telescopic sleeve 16, external dust can be prevented from entering the interior of the spring 6 and affecting the functional performance of the spring 6.

[0030] refer to Figure 1 , Figure 2 , Figure 5 The end of the connecting pipe 3 away from the rotating shaft 2 is connected to the main pipe. By setting up the main pipe, the water inside the main pipe enters the branch pipe 1 through the connecting pipe 3 and is then sprayed.

[0031] refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 The back of bracket 17 is bolted to the wall, which makes it easy to fix bracket 17. Example

[0032] refer to Figure 1 , Figure 4 , Figure 5 A three-dimensional dust suppression device for open-pit coal mine working faces includes a rotating mechanism comprising a rotating drum 10, which is fixedly sleeved on the surface of a water outlet 9. A water outlet pipe 11 is rotatably sleeved at the front end of the rotating drum 10. Nozzles 12 are provided on both sides of the front of the water outlet pipe 11. Water flows through the water outlet 9 into the rotating drum 10, then flows into the water outlet pipe 11 and is sprayed out from the nozzles 12 on both sides. The reaction force generated when the water is sprayed out drives the water outlet pipe 11 to rotate around the rotating drum 10, causing the nozzles 12 to rotate with the water outlet pipe 11, thereby achieving a wide-range spray.

[0033] refer to Figure 4 The rear end of the rotating drum 10 is fitted with a sealing ring 2 15. By setting the sealing ring 2 15 and fitting it with an interference fit, it has a dynamic sealing function to prevent leakage. It is made of nitrile rubber.

[0034] Brief description of the usage process: When the branch pipe 1 is rotated, the connecting block 4 rotates in the slot 5 of the bracket 17, which drives the buckle 7 to compress the spring 6 and disengage it from the slot 8. After adjusting to the target angle, the spring 6 resets and pushes the buckle 7 into the corresponding slot 8 to achieve positioning. At the same time, the rotation of the rotating shaft 2 and the connecting pipe 3 assists in the angle adjustment of the branch pipe 1 and keeps the branch pipe 1 stable. Finally, the spray output through the water outlet 9 covers the target area at the adjusted angle. The water flows through the water outlet 9 into the rotating drum 10, then flows into the water outlet pipe 11 and is sprayed out from the nozzles 12 on both sides. The reaction force generated when the water is sprayed out drives the water outlet pipe 11 to rotate around the rotating drum 10, so that the nozzles 12 rotate with the water outlet pipe 11 to achieve a large-area spray.
