Description

Technical Field

[0001] This utility model relates to the field of mine dust removal technology, specifically to a mine dry fog spraying device. Background Technology

[0002] During mining operations, a large amount of dust is generated in the mining, excavation and transportation processes. This dust permeates the mine working space, which not only reduces underground visibility and affects the normal operation of equipment and work efficiency, but also causes serious damage to the respiratory system of workers who are exposed to it for a long time. In some cases, it can even cause dust explosions when the dust concentration reaches a critical value, directly threatening the safe production of the mine and the lives of personnel.

[0003] However, existing dry fog spraying technology for mines still has significant shortcomings in practical applications. Existing technologies cannot flexibly adjust the spray range and intensity according to changes in mine dust concentration. When the dust concentration is low, maintaining a large-scale spraying operation will result in a significant waste of water resources. When the dust concentration increases and dust suppression needs to be intensified, the spray coverage is often incomplete, failing to form a continuous and complete water mist barrier. This causes some dust to pass through the spray area without being fully adsorbed, resulting in limited dust suppression effects. In addition, existing technologies have limitations in spray coverage dimensions, making it difficult to simultaneously achieve comprehensive coverage of different horizontal and vertical areas of the mine. This can easily create dust blind spots in some areas, failing to form a three-dimensional dust capture system and reducing the overall effectiveness of dust control. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a mine dry fog spraying device, which has the advantage of flexibly adjusting the spray range according to the dust concentration in the mine to form a three-dimensional wide fog curtain for comprehensive coverage.

[0017] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0018] Figures 1-10 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 10 The present invention will be further described below.

[0019] A dry fog spraying device for mines includes a U-shaped frame 1. A mounting groove 2 is provided on one side of the U-shaped frame 1 near the top. A motor 3 is fixedly installed on the bottom surface of the mounting groove 2. The output end of the motor 3 passes through the other side of the U-shaped frame 1. A turntable 4 is fixedly installed on the output end of the motor 3. A movable hole is provided at the front end of the turntable 4 near its side. Two sliding grooves 5 are symmetrically provided on the top surface of the U-shaped frame 1. Guide rods are fixedly installed inside the sliding grooves 5. A horizontal spraying component for dust suppression is provided on one side of the U-shaped frame 1, at the front end of the turntable 4. A drive unit is located inside the U-shaped frame 1, below the turntable 4. Two vertical spraying components for enhancing the dust suppression range and effect are symmetrically arranged inside the U-shaped frame 1. The horizontal spraying component consists of a first water storage pipe 6 and a T-shaped connecting rod 9. The vertical spraying component consists of a U-shaped frame 19 and a rectangular connecting rod 23.

[0020] In this implementation scheme, a U-shaped frame 1 is set as the basic support component of the entire mine dry fog spraying device to maintain the overall structural stability of the device. A mounting slot 2 is located on the side of the U-shaped frame 1 near the top, specifically for fixing and installing a motor 3. The motor 3 is externally powered and fixedly installed on the bottom surface inside the mounting slot 2. The output end passes through the U-shaped frame 1 and is fixedly connected to the turntable 4, driving the turntable 4 to rotate during operation. A movable hole is provided near the side of the front end of the turntable 4. When the motor 3 drives it to rotate, the movable hole can cooperate with the T-shaped connecting rod 9, converting its own circular motion into the reciprocating motion of the T-shaped connecting rod 9. A protective cover is fixedly installed on the side of the U-shaped frame 1 near the turntable 4 and above the turntable 4 to prevent falling debris from the mine from hitting the turntable 4 and the drive unit. Slides 5 are symmetrically arranged. Inside the top surface of the U-shaped frame 1, a guide rod is fixedly installed to accommodate the slider 18 of the vertical spray component, providing a sliding track for the slider 18. The core function of the horizontal spray component is to achieve dry fog spray dust suppression in the horizontal direction of the mine. Water is stored in the first water storage pipe 6 and sprayed out as mist through the nozzle. The T-shaped connecting rod 9 transmits power to drive the first water storage pipe 6 to swing, expanding the horizontal spray coverage area, thereby effectively reducing the dust concentration in the mine. The core function of the vertical spray component is to enhance the dust suppression range and effect in the mine. The second water storage pipe 20 is adjusted in position through the U-shaped frame 19, and the rectangular connecting rod 23 transmits power to drive the second water storage pipe 20 to swing, achieving vertical dry fog spray. Together with the horizontal spray component, it forms a three-dimensional wide fog curtain, expanding the overall dust suppression coverage area and improving the dust capture efficiency in the mine.

[0021] Specifically, the transverse spray assembly includes two support rods, which are symmetrically fixedly installed on one side of the U-shaped frame 1 near the turntable 4. A first water storage pipe 6 is rotatably installed between the two support rods. Several nozzles are fixedly installed equidistantly along the axial direction on the outer side of the first water storage pipe 6. An L-shaped water inlet pipe is rotatably installed at one end of the first water storage pipe 6, and the other end of the L-shaped water inlet pipe passes through the U-shaped frame 1.

[0022] In this embodiment, by symmetrically fixing two support rods on one side of the U-shaped frame 1 near the turntable 4, the main functions are to support and limit the movement, providing a stable base for the rotational installation of the first water storage pipe 6. This allows the first water storage pipe 6 to rotate around the axis between the two support rods. The first water storage pipe 6 is used to store water supplied by the L-shaped inlet pipe, providing sufficient water for spraying. On the other hand, several nozzles installed equidistantly along the axial direction on its outer side can convert the water stored inside into a mist and spray it out to achieve lateral dust suppression. At the same time, it can rotate around the two support rods and swing with the help of power to further expand the lateral spray coverage and improve the dust suppression effect.

[0023] Specifically, the transverse spray assembly also includes two connecting plates 7, which are symmetrically fixedly installed on the outer side of the first water storage pipe 6 near the turntable 4. A round rod 8 is fixedly installed between the two connecting plates 7, and a T-shaped connecting rod 9 is movably sleeved on the outer side of the round rod 8. The other end of the T-shaped connecting rod 9 passes through the movable hole.

[0024] In this embodiment, two connecting plates 7 are symmetrically fixedly installed on the outer side of the first water storage pipe 6 near the turntable 4, and the round rod 8 is stably fixed on the first water storage pipe 6, so that the movement of the round rod 8 can be synchronously transmitted to the first water storage pipe 6. The round rod 8 is fixedly installed between the two connecting plates 7, and a T-shaped connecting rod 9 is movably sleeved on the outer side, which mainly acts as a bridge for power transmission. It can receive the reciprocating motion transmitted by the T-shaped connecting rod 9, and transmit the motion to the first water storage pipe 6 through the two connecting plates 7, causing the first water storage pipe 6 to rotate around the support rod. The outer side of the T-shaped connecting rod 9 is movably sleeved on the outer side of the round rod 8, and the other end passes through the movable hole of the turntable 4, which can convert the circumferential motion generated by the rotation of the turntable 4 into its own reciprocating motion, and then transmit the reciprocating motion to the round rod 8, thereby driving the first water storage pipe 6 to rotate, realizing the oscillating spray of the transverse spray assembly.

[0025] Specifically, the drive unit includes a rectangular mounting block 10, which is fixedly installed on the inner top surface of the U-shaped frame 1 near the turntable 4. A mounting rod 11 is rotatably mounted on one side of the rectangular mounting block 10, and a transmission rod 12 is fixedly mounted on the other end of the mounting rod 11. Two connecting holes 13 are opened on one side of the transmission rod 12. The connecting hole 13 near the top of the transmission rod 12 is larger, and the connecting hole 13 near the bottom of the transmission rod 12 is smaller. The transmission rod 12 is positioned between the round rod 8 and the turntable 4. One end of the T-shaped connecting rod 9 passes through the connecting hole 13 near the top of the transmission rod 12, and the other end of the push rod 16 is movably sleeved inside the connecting hole 13 near the bottom of the transmission rod 12.

[0026] In this embodiment, by fixing the rectangular mounting block 10 to the inner top surface of the U-shaped frame 1 near the turntable 4, a base for the mounting rod 11 to rotate is provided, allowing the mounting rod 11 to rotate stably on one side. One end of the mounting rod 11 is rotatably mounted on one side of the rectangular mounting block 10, and the other end is fixedly mounted on the transmission rod 12, providing a pivot point for the transmission rod 12. This allows the transmission rod 12 to rotate flexibly around the connection point between the mounting rod 11 and the rectangular mounting block 10. The transmission rod 12 receives the reciprocating driving force transmitted from the T-shaped connecting rod 9 in the transverse spray assembly. When the motor 3 drives the turntable 4 to rotate, the turntable 4 passes through the movable hole. The T-shaped connecting rod 9 is driven to reciprocate. During the reciprocating motion, the T-shaped connecting rod 9 will exert a pushing and pulling force on the connecting hole 13 at the top of the through transmission rod 12. After receiving this power, the transmission rod 12 will rotate around the connection point between the mounting rod 11 and the rectangular mounting block 10, and then transmit the power to the push rod 16 of the drive unit through the smaller connecting hole 13 at the bottom. The two connecting holes 13 are opened on one side of the transmission rod 12. The connecting hole 13 near the top of the transmission rod 12 is larger, and the connecting hole 13 near the bottom is smaller. The larger connecting hole 13 at the top allows the T-shaped connecting rod 9 to pass through, and the smaller connecting hole 13 at the bottom allows the push rod 16 to be fitted.

[0027] Specifically, the drive unit also includes a T-shaped groove 14, which is opened at the bottom of the rectangular mounting block 10. A drive rod 15 is movably engaged inside the T-shaped groove 14. A push rod 16 is fixedly installed on the side of the drive rod 15 near the transmission rod 12. Two insert rods 17 are symmetrically and rotatably installed at the bottom of the drive rod 15.

[0028] In this embodiment, by creating a T-shaped groove 14 at the bottom of the rectangular mounting block 10, the movement direction of the drive rod 15 is restricted by a movable snap-fit ​​mechanism. This allows the drive rod 15 to slide back and forth along the length of the T-shaped groove 14, preventing deviation or jamming during its movement. The drive rod 15 is movably snapped into the T-shaped groove 14. A push rod 16 is fixed on one side, and two insert rods 17 are symmetrically rotated and installed at the bottom. These insert rods receive the pushing and pulling forces transmitted by the push rod 16 and slide back and forth along the T-shaped groove 14. Simultaneously, they drive the two insert rods 17 at the bottom to move synchronously, transmitting power to the rectangular connecting rod 23 of the vertical spray assembly. The two insert rods 17 are symmetrically rotated and installed at the bottom of the drive rod 15, movably fitted into the insertion holes 24 of the rectangular connecting rod 23 of the vertical spray assembly. Their main function is to transmit the reciprocating motion of the drive rod 15 to the rectangular connecting rod 23, causing the rectangular connecting rod 23 to slide along the guide post 22, thereby driving the second water storage pipe 20 to rotate back and forth to achieve spraying.

[0029] Specifically, the vertical spray assembly includes a U-shaped frame 19, which is movably installed inside the U-shaped frame 1. A slider 18 is fixedly installed on the top of the U-shaped frame 19, and the slider 18 is movably fitted inside the slide groove 5. A guide rod passes through the slider 18. A second water storage pipe 20 is rotatably installed inside the U-shaped frame 19. An L-shaped water inlet pipe 20 is rotatably installed at the bottom of the second water storage pipe 20. Spray nozzles are fixedly installed equidistantly along the axial direction on the outer side of the second water storage pipe 20.

[0030] In this embodiment, the U-shaped frame 19 is movably installed inside the U-shaped frame 1, with a slider 18 fixed at the top and a second water storage pipe 20 rotatably installed inside. This serves two purposes: firstly, the slider 18 slides within the groove 5, adjusting the position of the second water storage pipe 20; secondly, it provides stable rotational support for the second water storage pipe 20, ensuring smooth oscillation and spraying. The slider 18 is fixed to the top of the U-shaped frame 19, movably fitted inside the groove 5, and penetrated by a guide rod. Its core function is to drive the U-shaped frame 19 to slide along the groove 5, adjusting the position of the U-shaped frame 19 through the sliding of the slider 18. The second water storage pipe 20 is positioned within the U-shaped frame 1. When there is little dust, the two U-shaped frames 19 can be manually separated to the sides inside the U-shaped frame 1, without obstructing the passage of personnel or other equipment, thus improving the flexibility of the device. The second water storage pipe 20 is rotatably installed inside the U-shaped frame 19, with the bottom rotatably connected to the second L-shaped water inlet pipe. Spray nozzles are equidistantly installed on the outer side along the axial direction. On one hand, it stores the water source transported by the second L-shaped water inlet pipe, providing water volume support for spraying. On the other hand, it swings around the U-shaped frame 19, cooperating with the outer spray nozzles to atomize the water and spray it vertically. The spraying expands the vertical spray coverage area, while the axially equidistant nozzles form a wide vertical mist curtain, enhancing the dust capture effect in the vertical area of ​​the mine. The nozzles are fixed axially equidistantly on the outside of the second water storage pipe 20. Through the even distribution of several nozzles, a continuous, wide mist curtain is formed in the vertical direction, increasing the contact area between the mist water and the dust in the mine, and improving the settling efficiency of dust at different heights. The top of the U-shaped frame 19 has an installation hole, inside which a fixing rod is movably installed. One side of the U-shaped frame 19 has an adjustment hole connected to the installation hole for fixing. A second spring is fixedly installed at the bottom of the rod, and a lever is fixedly installed on the outside of the fixed rod. A fixing hole is opened on the top surface of the U-shaped frame 1. When the U-shaped frame 19 moves along the slide 5 to the edge of the slide 5, the fixed rod will be inserted into the fixing hole to fix the position of the U-shaped frame 19, so that the U-shaped frame 19 will not shake or move when the vertical spraying assembly is working. When it is necessary to move the U-shaped frame 19 to the inside side of the U-shaped frame 1, simply press the lever down manually. The fixed rod will disengage from the fixing hole, the second spring will be compressed, and the U-shaped frame 19 can be moved at this time.

[0031] Specifically, the vertical spray assembly also includes a movable slot 21, which is located outside the second water storage pipe 20. A guide post 22 is fixedly installed inside the movable slot 21, and a rectangular connecting rod 23 is movably installed inside the movable slot 21. The guide post 22 passes through the rectangular connecting rod 23. An insertion hole 24 is provided at the top of the rectangular connecting rod 23, and the insertion rod 17 is movably sleeved inside the insertion hole 24. A first spring 25 is fixedly installed at the bottom of the rectangular connecting rod 23, and the other end of the first spring 25 is fixedly installed to the bottom surface of the movable slot 21. The first spring 25 is movably sleeved outside the guide post 22.

[0032] In this embodiment, by opening the movable groove 21 on the outside of the second water storage pipe 20, installation and movement space are provided for the guide post 22, the rectangular connecting rod 23, and the first spring 25. The guide post 22 is fixed inside the movable groove 21 and passes through the rectangular connecting rod 23. On the one hand, it provides precise guidance for the sliding of the rectangular connecting rod 23, ensuring that it can only slide up and down along the axial direction of the guide post 22, avoiding tilting or jamming. On the other hand, it provides installation support for the first spring 25, allowing the first spring 25 to be stably fitted on the outside, ensuring the normal realization of the reset function of the first spring 25. The rectangular connecting rod 23 is movably installed inside the movable groove 21. The top has an insertion hole 24, the bottom has a fixed first spring 25, and the guide post 22 passes through it. It cooperates with the insertion rod 17 through the insertion hole 24, receives the power transmitted by the insertion rod 17 and slides along the guide post 22, thereby driving the second water storage pipe 20 to rotate. The first spring 25 is movably sleeved on the outside of the guide post 22, with one end fixed to the bottom of the rectangular connecting rod 23 and the other end fixed to the bottom surface inside the movable groove 21. When the rectangular connecting rod 23 is manually pulled down, the first spring 25 is compressed and stores elastic potential energy. When the external force weakens or disappears, the first spring 25 releases elastic potential energy and pushes the rectangular connecting rod 23 to slide up and reset.

[0033] In summary: When using this utility model, only the horizontal spray component is activated when the dust level is low. When the dust level is high and the horizontal spray component cannot effectively reduce dust, both the horizontal and vertical spray components must be activated simultaneously. Before activating the vertical spray component, the two U-shaped frames 19 are manually moved along the slide groove 5 towards the center of the U-shaped frame 1. The slider 18 at the top of the U-shaped frame 19 slides along the guide rod in the slide groove 5. After moving to the appropriate position, the compressed second spring releases its elastic potential energy, inserting the fixing rod into the fixing hole to fix the position of the U-shaped frame 19. Based on the position of the bottom insertion rod 17 of the drive rod 15, the second spring is manually rotated... With the second water storage pipe 20 in place, bring the rectangular connecting rod 23 in the movable groove 21 on the outside of the second water storage pipe 20 close to the insertion rod 17. At this time, manually pull the rectangular connecting rod 23 downward. The rectangular connecting rod 23 slides downward along the guide post 22 in the movable groove 21, and the first spring 25 at the bottom is compressed. After aligning the insertion hole 24 at the top of the rectangular connecting rod 23 with the insertion rod 17, release the rectangular connecting rod 23. The first spring 25 releases its elastic potential energy and pushes the rectangular connecting rod 23 upward, so that the insertion rod 17 is inserted into the insertion hole 24. Then connect the high-pressure water pump and water source to the L-shaped water inlet pipe 1 and L-shaped water inlet pipe 2. Connect the motor 3 to an external power source. The operation drives the turntable 4 at the output end to rotate. The turntable 4 drives the T-shaped connecting rod 9 to reciprocate through the movable hole at the front end. The T-shaped connecting rod 9 drives the round rod 8 in the transverse spray assembly to move. The round rod 8 drives the first water storage pipe 6 to rotate around the two support rods through the two connecting plates 7. The nozzles on the outside of the first water storage pipe 6 atomize the water delivered by the L-shaped inlet pipe and spray it in an oscillating manner to achieve transverse dust suppression. The drive rod 15 reciprocates, and pushes or pulls the rectangular connecting rod 23 through the insertion rod 17 at the bottom of the drive rod 15, causing the second water storage pipe 20 to reciprocate around the U-shaped frame 19. The nozzles on the outside of the second water storage pipe 20 spray the L-shaped inlet pipe. After the water delivered by the second inlet pipe is atomized, it is sprayed in an oscillating manner, forming a three-dimensional wide fog screen with the horizontal spray component. After use, first turn off the power to the motor 3 so that the turntable 4 stops rotating. Then, manually pull down the rectangular connecting rod 23 to separate the insertion rod 17 from the insertion hole 24. Next, manually rotate the second water storage pipe 20 to move the rectangular connecting rod 23 away from the insertion rod 17. Then, manually press down the lever on the U-shaped frame 19 to disengage the fixing rod from the fixing hole on the top surface inside the U-shaped frame 1. Finally, manually move the second water storage pipe 20 and the U-shaped frame 19 to the side inside the U-shaped frame 1. At this time, it will not obstruct the passage of personnel and other equipment.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
