Technical Field
[0001] This invention relates to the field of dust suppression technology in well construction, specifically to a dust suppression device for vertical shafts. Background Technology
[0002] Vertical shafts are mine tunnels perpendicular to the ground and are key connecting structures between underground engineering and the surface. They are widely used in mining, water conservancy and hydropower, urban underground engineering, and national defense engineering. They are core facilities for deep resource development. When constructing vertical shafts, due to their vertical space, concentrated working face, and rapid dust diffusion, higher requirements are placed on dust suppression equipment, necessitating the use of specialized dust suppression equipment for vertical shafts.
[0003] In the existing technology, when dust suppression equipment is used to suppress dust in vertical shafts, the suction ports on the equipment are mostly fixed in one position and cannot be moved. They can only cover a fixed horizontal area, which limits the dust collection range. Frequent repositioning of the equipment is required, resulting in poor dust collection effect and efficiency. Furthermore, the fixed suction ports are prone to forming local high negative pressure areas, causing dust to be quickly sucked up and then re-raised due to airflow turbulence.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1.

As gear three, gear four, and ring rack one mesh with each other, the rotation of gear three drives gear four and ring rack one to rotate. The rotation of ring rack one drives the air shell and duct to rotate, causing the suction port of the duct to move up and down and rotate at the same time. This allows the suction port of the duct to cover a larger area, improving the dust collection rate. Furthermore, the rotation of the suction port of the duct changes the airflow direction periodically, making the negative pressure field distribution more uniform and reducing the dust escape channels.
[0015] 2. When dust is collected through the duct, water in the water tank enters the water shell through the telescopic water pipe and is then sprayed out through the water mist nozzle. The water mist increases the humidity of the airflow, reduces the Brownian motion intensity of the dust particles, and at the same time, the dust is quickly removed from the airflow through gravity settling, shortening the collection time. Moreover, the water mist and dust combine to form mud-like particles, which have enhanced adhesion and are not easily re-raised by the airflow, effectively blocking the dust diffusion path. The combination of wind suction and water mist dust suppression effectively improves the dust removal and dust suppression efficiency. Attached Figure Description

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:
[0019] Please see Figures 1-8As shown, a dust suppression device for vertical shafts includes a mounting base 1; a placement plate 3 is provided on the inner side of the outer wall of the mounting base 1 via a limiting post 2; a reciprocating rod 4 is rotatably connected to the bottom end of the outer wall of the placement plate 3; a reciprocating plate 5 is provided on the outer side wall of the reciprocating rod 4; an air shell 6 is provided on the outer side wall of the reciprocating plate 5; a set of air ducts 7 is provided at the bottom end of the outer wall of the air shell 6; a suction fan 8 is fixedly connected to the top end of the outer wall of the placement plate 3; a telescopic pipe 9 is provided at the output end of the suction fan 8, and the bottom end of the outer wall of the telescopic pipe 9 passes through the placement plate 3 and is connected to the air shell 6; an exhaust pipe 10 is provided at the exhaust end of the suction fan 8; A guide rod 11 is fixedly connected to the bottom of the outer wall of the placement plate 3, and the guide rod 11 is slidably connected to the reciprocating plate 5; a gear 12 is fixedly connected to the outer wall of the reciprocating rod 4; a motor 13 is fixedly connected to the top of the outer wall of the placement plate 3; the output end of the motor 13 is provided with a rotating shaft 14, and the bottom of the outer wall of the rotating shaft 14 passes through the placement plate 3; a gear 2 15 is fixedly connected to the bottom of the outer wall of the rotating shaft 14, and the gear 2 15 meshes with the gear 12. By installing the mounting base 1 above the shaft, the motor 13 drives the rotating shaft 14 and the gear 2 15 to rotate. The gears mesh with each other, causing gear 2 15 to drive the reciprocating rod 4 to rotate via gear 1 12. Because the reciprocating plate 5 is limited by the guide rod 11, the rotation of the reciprocating rod 4 causes the reciprocating plate 5 to move up and down reciprocally. This causes the reciprocating plate 5 to drive the air housing 6 to move up and down reciprocally within the shaft. At this time, the suction fan 8 operates, drawing air through the telescopic pipe 9, air housing 6, and air duct 7 to absorb dust from the shaft, which is then discharged through the exhaust pipe 10. Because the air duct 7 is in a reciprocating motion, the position for absorbing dust continuously moves, and this reciprocating motion causes the suction port of the air duct 7 to form a "sweeping" motion in the vertical direction. "The coverage solves the problem of local dust accumulation, and the up-and-down movement can track the dust height in real time, ensuring that high-concentration areas are always in a negative pressure field. When the air inlet of the duct 7 moves up and down, the high-speed airflow forms a periodic disturbance field in the vertical direction, breaking the static balance of dust attached to the well wall and enhancing the ability to peel off stubborn dust. When the air inlet of the duct 7 moves up and down, the high-speed airflow at the edge forms the Coanda effect, causing the dust-laden air to flow along the surface of the air inlet, reducing the diffusion of dust to the middle of the well, improving the dust collection effect and efficiency, and solving the problem of secondary dust re-entrainment."
[0020] A water tank 21 is fixedly connected to the top of the outer wall of the placement plate 3; a water shell 22 is fixedly connected to the outer wall of the ring rack 19; the bottom of the outer wall of the water tank 21 is connected to the water shell 22 through a telescopic water pipe 23; a set of water mist nozzles 24 are provided at the bottom of the outer wall of the water shell 22; the water mist nozzles 24 are matched with the air duct 7. When the air duct 7 collects dust, the water in the water tank 21 enters the water shell 22 through the telescopic water pipe 23 and is then sprayed out through the water mist nozzles 24, which increases the humidity of the airflow and reduces the Brownian motion intensity of the dust particles. At the same time, the dust is quickly removed from the airflow through the gravity settling effect, shortening the collection time. After the water mist combines with the dust, it forms mud-like particles with enhanced adhesion, making it difficult for the airflow to re-raise them, effectively blocking the dust diffusion path. The combination of wind suction and water mist dust suppression effectively improves the dust removal and dust suppression efficiency.
[0021] The air housing 6 includes an upper plate 601 and a lower housing 602; the outer wall of the reciprocating plate 5 is slidably connected to the inner wall of the lower housing 602; the upper plate 601 is fixedly connected to the telescopic pipe 9; the upper plate 601 and the lower housing 602 are rotatably connected; a gear 16 is slidably connected to the outer wall of the reciprocating rod 4, and the top of the outer wall of the gear 16 is rotatably connected to the bottom of the outer wall of the reciprocating plate 5; a gear 17 is rotatably connected to the bottom of the outer wall of the reciprocating plate 5; an annular rack 18 is fixedly connected to the inner wall of the lower housing 602; the gears 16, 17, and 18 mesh with each other, and when the reciprocating rod 4 rotates, the reciprocating rod 4 drives the gear 16 to rotate. Simultaneously, the up-and-down movement of the reciprocating plate 5 drives the gear 16 to move up and down, causing the gear 16 to rotate while moving up and down. Because the gears 16, 17, and 18 mesh with each other, the rotation of the gear 16 drives the gears 17 and 18 to rotate. The rotation of the 18 drives the air housing 6 and the duct 7 to rotate, causing the suction port of the duct 7 to move up and down while rotating. This allows the suction port of the duct 7 to cover a larger area, improving the dust collection rate. Furthermore, the rotation of the suction port of the duct 7 periodically changes the airflow direction, making the negative pressure field distribution more uniform and reducing dust escape channels.
[0022] A filter screen 27 is fixedly connected to the inner wall of the duct 7; a rotating rod 28 is rotatably connected to the inner wall of the filter screen 27; a set of suction fan blades 29 is fixedly connected to the outer wall of the rotating rod 28; a set of cleaning plates 30 is fixedly connected to the outer wall of the rotating rod 28; one side of the outer wall of the set of cleaning plates 30 is in contact with one side of the outer wall of the filter screen 27. When the suction fan 8 performs suction and dust reduction through the telescopic pipe 9, air shell 6 and duct 7, the air force in the duct 7 will drive the suction fan blades 29 to rotate, the suction fan blades 29 will drive the rotating rod 28 to rotate, and the rotating rod 28 will drive the cleaning plates 30 to rotate, so that the cleaning plates 30 clean the dust or mud-like particles on the filter screen 27, so that the filter screen 27 filters the dust or mud-like particles, thereby avoiding damage to the suction fan 8 by mud-like particles and dust. At the same time, the rotation of the cleaning plates 30 also avoids the problem of filter screen 27 clogging.
[0023] A pair of connecting pipes fix a ring rack 19 to the top of the outer wall of the reciprocating plate 5; a set of air ducts 7 are rotatably connected to the air housing 6, and the set of air ducts 7 are all connected to the air housing 6; a set of gears 20 are fixed to the outer wall of the set of air ducts 7; the set of gears 20 meshes with the ring rack 19; the air ducts 7 are in an inverted Z shape, and when the air housing 6 and the air ducts 7 rotate, the outer wall of the air ducts 7 is fixed with gears 20; the set of gears 20 meshes with the ring rack 19, and the ring rack... The second rack 19 does not rotate, but moves up and down with the reciprocating plate 5. When the fifth gear 20 rotates, the second rack 19 rotates, causing the fifth gear 20 to drive the air duct 7 to rotate. Through the shape of the air duct 7, the air intake of the air duct 7 further expands the coverage area. Through the combination of up-and-down reciprocating motion and rotation, the air intake of the air duct 7 forms a three-dimensional sweeping coverage, so that dust sources are effectively captured. This device has the functions of expanding the coverage area, enhancing the uniformity of airflow, improving adaptability, and suppressing secondary dust.
[0024] A bevel gear 31 is fixedly connected to one end of the outer wall of the rotating rod 28; a circular rod 32 is rotatably connected to the inner wall of the duct 7; a bevel gear 33 is fixedly connected to the outer wall of the circular rod 32, and the bevel gear 33 meshes with the bevel gear 31; a pair of rotating plates 34 are fixedly connected to the outer wall of the circular rod 32; one end of the outer wall of each pair of rotating plates 34 matches the inner wall of the duct 7. When the rotating rod 28 rotates, the rotating rod 28 drives the bevel gear 31 to rotate, the bevel gear 31 drives the bevel gear 33 and the circular rod 32 to rotate, and the circular rod 32 drives the rotating plates 34 to rotate, so that the rotating plates 34 clean the mud-like particles or dust adhering to the inner wall of the duct 7, so that mud-like particles or dust are not easily accumulated in the duct 7.
[0025] An annular rack 25 is fixedly connected to the bottom of the outer wall of the air housing 6 via a set of connecting rods. A set of water mist nozzles 24 are rotatably connected to the water housing 22. Gears 26 are fixedly connected to the outer walls of the water mist nozzles 24. Gears 26 mesh with the annular rack 25. When the air housing 6 rotates, it drives the annular rack 25 to rotate via the connecting rods. Since gears 26 are fixedly connected to the outer walls of the water mist nozzles 24 and mesh with the annular rack 25, and gears 26 do not rotate, the rotation of the annular rack 25 drives gears 26 to rotate, which in turn drives the water mist nozzles 24 to rotate. This expands the spray range of the water mist nozzles 24, ensuring that after the water mist nozzles 24 spray, the duct 7 rotates to the desired position to combine the water mist with the dust, forming mud-like particles that are absorbed, effectively solving the dust problem inside the vertical shaft.
[0026] A square through groove 35 is formed on one side of the outer wall of the rotating rod 28; a collection shell 36 is fixedly connected to one side of the outer wall of the rotating rod 28, and the collection shell 36 is connected to the square through groove 35. The collection shell 36 is L-shaped; a pull plate 37 is slidably connected to the bottom end of the inner side wall of the collection shell 36; a threaded groove 38 is formed on one side of the outer wall of the pull plate 37; a bolt 39 is threadedly connected to one side of the outer wall of the collection shell 36, and the bolt 39 matches the threaded groove 38; a handle 40 is fixedly connected to one side of the outer wall of the pull plate 37. When the rotating plate 34 rotates, mud-like particles or dust enter the collection shell 36 through the square through groove 35 on the rotating plate 34 and are collected. This solves the problem of collecting mud-like particles or dust. When the mud-like particles or dust cleaned off the filter screen 27 flow down the air duct 7, they will also be collected in the collection shell 36. When it is necessary to remove the mud-like particles or dust from the collection shell 36, the bolt 39 is turned to move the thread out of the thread groove 38. At this time, the pull plate 37 is released. Then, the pull plate 37 is pulled by the handle 40 to open the bottom of the collection shell 36. At this time, the mud-like particles or dust in the collection shell 36 can be removed, making the removal of mud-like particles or dust more convenient and the collection and storage of mud-like particles or dust more convenient. Example 2:
[0027] Please see Figure 1 and Figure 9As shown, a second motor 41 is fixedly connected to the bottom of the outer wall of the mounting base 1 via a fixing block; a rotating column 42 is provided at the output end of the second motor 41; a first bevel gear 43 is fixedly connected to one end of the outer wall of the rotating column 42; the mounting base 1 is provided with a reciprocating column 44, and the reciprocating column 44 matches the mounting base 1; the bottom of the outer wall of the reciprocating column 44 is rotatably connected to the top of the outer wall of the placement plate 3; a limiting column 2 is slidably connected to the mounting base 1, and the bottom of the outer wall of the limiting column 2 is fixedly connected to the top of the outer wall of the placement plate 3; a second bevel gear 45 is slidably connected to the outer wall of the reciprocating column 44; the bottom of the outer wall of the second bevel gear 45 is rotatably connected to the top of the outer wall of the mounting base 1 via a set of auxiliary rods; the first The second bevel gear 45 meshes with the first bevel gear 43. The motor 41 drives the rotating column 42 and the first bevel gear 43 to rotate. The first bevel gear 43 drives the second bevel gear 45 to rotate. Since the second bevel gear 45 is slidably connected to the reciprocating column 44, the second bevel gear 45 drives the reciprocating column 44 to rotate, causing the reciprocating column 44 to move up and down. At this time, the second bevel gear 45 does not move. The movement of the reciprocating column 44 drives the placement plate 3 to move, thereby driving the suction dust suppression mechanism and water mist dust suppression mechanism in this device to move up and down. This allows the device to be adjusted in position in the vertical shaft as needed, so as to better suppress and collect dust.
[0028] In use, the present invention is installed above the shaft. Motor 13 drives the rotating shaft 14 and gear 15 to rotate. Since gear 15 meshes with gear 12, it drives the reciprocating rod 4 to rotate via gear 12. Because the reciprocating plate 5 is limited by the guide rod 11, the rotation of the reciprocating rod 4 causes the reciprocating plate 5 to move up and down, causing the reciprocating plate 5 to move the air housing 6 up and down within the shaft. At this time, the suction fan 8 operates, drawing dust from the shaft through the telescopic pipe 9, air housing 6, and air duct 7, and then discharging it through the exhaust pipe 10. Because the air duct 7 moves up and down, the dust absorption position is constantly adjusted. The vertical movement of the air duct 7's intake port creates a "sweeping" coverage in the vertical direction, solving the problem of localized dust accumulation. Furthermore, the vertical movement allows for real-time tracking of dust height, ensuring that high-concentration areas remain under negative pressure. Additionally, the high-speed airflow during the vertical movement of the intake port creates a periodic disturbance field in the vertical direction, breaking the static balance of dust adhering to the well wall and enhancing the ability to remove stubborn dust. Moreover, the high-speed airflow at the edge of the intake port creates a Coanda effect, causing dust-laden air to flow along the surface of the intake port, reducing dust diffusion towards the center of the well. This improves the dust collection effect and efficiency while solving the problem of secondary dust re-entrainment.
[0029] When the reciprocating rod 4 rotates, it drives the gear 16 to rotate. At the same time, the up-and-down movement of the reciprocating plate 5 drives the gear 16 to move up and down. The gear 16 rotates and moves up and down at the same time. Because the gears 16, 17, and 18 mesh with each other, the rotation of the gear 16 drives the gears 17 and 18 to rotate. The rotation of the 18 drives the air housing 6 and the duct 7 to rotate. This causes the suction port of the duct 7 to move up and down and rotate at the same time, so that the suction port of the duct 7 can cover a larger area and improve the dust collection rate. In addition, the rotation of the suction port of the duct 7 changes the airflow direction periodically, making the negative pressure field distribution more uniform and reducing the dust escape channels.
[0030] When the air casing 6 and the air duct 7 rotate, gears 20 are fixedly connected to the outer wall of the air duct 7. A set of gears 20 meshes with the ring rack 19. The ring rack 19 does not rotate but moves up and down with the reciprocating plate 5. When the gears 20 rotate, the ring rack 19 rotates, causing the gears 20 to drive the air duct 7 to rotate. Through the shape of the air duct 7, the air intake of the air duct 7 further expands its coverage area. Through the combination of up-and-down reciprocating motion and rotation, the air intake of the air duct 7 forms a three-dimensional sweeping coverage, so that all dust sources are effectively captured. This device has the functions of expanding the coverage area, enhancing the uniformity of airflow, improving adaptability, and suppressing secondary dust.
[0031] When the duct 7 collects dust, the water in the water tank 21 enters the water shell 22 through the telescopic water pipe 23, and is then sprayed out through the water mist nozzle 24. This water mist increases the humidity of the airflow, reduces the Brownian motion intensity of the dust particles, and at the same time, the dust is quickly removed from the airflow through gravity settling, shortening the collection time. Furthermore, the water mist combines with the dust to form mud-like particles, which have enhanced adhesion and are not easily re-raised by the airflow, effectively blocking the dust diffusion path. This combination of wind-powered dust collection and water mist dust suppression effectively improves the dust removal and dust suppression efficiency.
[0032] When the air housing 6 rotates, it drives the ring rack 25 to rotate via a set of connecting rods. Since gears 26 are fixed to the outer walls of a set of water mist nozzles 24, and gears 26 mesh with the ring rack 25, and gears 26 do not rotate, the rotation of the ring rack 25 drives gears 26 to rotate, which in turn drives the water mist nozzles 24 to rotate, thus expanding the spray range of the water mist nozzles 24. After the water mist nozzles 24 spray, the air duct 7 rotates to that position to combine the water mist with the dust to form mud-like particles for absorption, effectively solving the dust problem inside the vertical shaft.
[0033] When the suction fan 8 performs dust extraction through the telescopic pipe 9, air housing 6, and air duct 7, the airflow inside the air duct 7 drives the suction fan blades 29 to rotate. The suction fan blades 29 drive the rotating rod 28 to rotate, and the rotating rod 28 drives the cleaning plate 30 to rotate. This causes the cleaning plate 30 to clean the dust or mud-like particles on the filter screen 27, thus filtering the dust or mud-like particles and preventing damage to the suction fan 8. At the same time, the rotation of the cleaning plate 30 also prevents the filter screen 27 from clogging.
[0034] When the rotating rod 28 rotates, it drives the bevel gear 31 to rotate, which in turn drives the bevel gear 33 and the circular rod 32 to rotate. The circular rod 32 then drives the rotating plate 34 to rotate, which cleans the mud-like particles or dust adhering to the inner wall of the duct 7, making it less likely for mud-like particles or dust to accumulate inside the duct 7.
[0035] When the rotating plate 34 rotates, mud-like particles or dust enter the collection shell 36 through the square groove 35 on the rotating plate 34 and are collected, thus solving the problem of collecting mud-like particles or dust. Mud-like particles or dust cleaned off the filter screen 27 also flow down the air duct 7 and are collected into the collection shell 36. When it is necessary to remove the mud-like particles or dust from the collection shell 36, the thread is moved out of the thread groove 38 by rotating the bolt 39. At this time, the pull plate 37 is released from its fixation. Then, the bottom of the collection shell 36 is opened by pulling the pull plate 37 with the handle 40. At this time, the mud-like particles or dust in the collection shell 36 can be removed, making the removal of mud-like particles or dust more convenient and the collection and storage of mud-like particles or dust more convenient.
[0036] Motor 41 drives rotating column 42 and first bevel gear 43 to rotate. First bevel gear 43 drives second bevel gear 45 to rotate. Since second bevel gear 45 is slidably connected to reciprocating column 44, second bevel gear 45 drives reciprocating column 44 to rotate, causing reciprocating column 44 to move up and down. At this time, second bevel gear 45 does not move. The movement of reciprocating column 44 drives placement plate 3 to move, thereby driving the suction dust suppression mechanism and water mist dust suppression mechanism in this device to move up and down. This allows the device to be adjusted in position in the vertical shaft as needed, so as to better suppress and collect dust.
