Description

Technical Field

[0001] This invention relates to the field of dust suppression equipment, and more specifically, to an adaptive dust suppression device for online monitoring of coal mining dust. Background Technology

[0002] Coal, a solid combustible mineral formed from ancient plants undergoing biochemical and physicochemical changes underground, is known as "black gold" and the "food" of industry, and has been one of humanity's primary energy sources since the 18th century. Coal mining is a complex and crucial process, and an effective transportation system plays a vital role in the entire production chain.

[0003] When coal is mined, it needs to be placed on a conveyor belt for transportation. During transportation, the coal needs to move, which will bring out a lot of dust, so dust suppression devices are needed to suppress the dust. Existing dust suppression systems operate in a relatively fixed manner, resulting in a limited spray area and spacing between adjacent nozzles, which affects the dust suppression effect. Furthermore, in existing devices, the atomizing head is always exposed, whether in operation or not. After each use, water accumulates on the outside of the atomizing head, causing external dust to adhere and clump over time. This directly impacts the atomization effect and ultimately reduces dust suppression efficiency, making the system unsuitable for widespread use.

[0004] To address this, an adaptive dust suppression device for online monitoring of coal mining dust is proposed. Summary of the Invention

Preferably, the outer side of the moving tube is tightly fitted to the inner wall of the horizontal tube, and sealing rings are provided on both sides of the moving tube.

[0008] Preferably, the shrink spray assembly includes a movable block slidably connected inside the circular block, the movable block having small holes evenly distributed inside, a support block fixedly connected to the upper end of the circular block, the support block having water holes evenly distributed inside, a square rod slidably connected inside the support block, the lower end of the square rod being fixedly connected to the upper end of the movable block, and a first spring fixedly connected to the lower end of the support block.

[0009] Preferably, a gas shell is fixedly connected to the lower end of the horizontal tube, a piston block is slidably connected inside the gas shell, a support tube is fixedly connected to one side of the piston block, a circular shell is rotatably connected to the outside of the circular block, a plurality of vent holes communicating with the circular shell are evenly opened on the circular block, a first one-way valve is fixedly connected to one side of the support tube, a second one-way valve is fixedly connected to one side of the gas shell, and the gas shell is distributed on both sides of the rectangular opening.

[0010] Preferably, a ventilation groove is provided on one side of the gas shell.

[0011] Preferably, a support ring is fixedly connected to the lower outer end of the circular block, and rectangular rods are slidably connected to both sides of the support ring. A baffle is fixedly connected to one side of the rectangular rod, a second spring is sleeved on the rod wall of the rectangular rod, and a gravity block is fixedly connected to the other side of the rectangular rod. One end of the second spring is connected to the support ring, and the other end is fixedly connected to the gravity block.

[0012] Preferably, the right side of the horizontal tube is fixedly connected to the housing, the upper end of the housing is provided with a groove, a protrusion is slidably connected inside the groove, a third spring is fixedly connected to the upper end of the protrusion, the upper end of the third spring is fixedly connected to the inner wall of the groove, an arc-shaped block is fixedly connected to the right side of the reciprocating screw, a hollow block is fixedly connected to the left side of the support frame, a coil spring is fixedly connected inside the hollow block, and one side of the coil spring is fixedly connected to the right side of the housing.

[0013] Preferably, the left side of the hollow block is rotatably connected to the shell.

[0014] Preferably, dust detection devices are fixedly connected to both sides of the support frame. The dust detection devices are electrically connected to the motor and can control the start and stop of the motor.

[0015] Preferably, the upper end of the support frame is provided with a support rod, and a fan is fixedly connected to the upper end of the support rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) When performing dust suppression work, the moving tube is moved left and right continuously by the motor, and the round block is rotated by the gear and tooth block. In this way, the area of ​​liquid spraying is more uniform and wider when performing dust suppression, thereby improving the dust suppression effect.

[0017] (2) The movable block can be located inside the round block when not in use, which can effectively prevent the movable block from being exposed to the air for a long time, and prevent dust from adhering to the outside of the movable block and affecting the atomization effect. Furthermore, when the movable block is retracted to the lower end inside the round block, the lower end of the round block has a pushing effect on the dirt on the outside of the movable block, thereby ensuring that there is no dust on the outside of the movable block, which is conducive to long-term use and ensures the effectiveness of the atomization.

[0018] (3) By moving the circular block left and right, under the action of the support tube, the piston block moves left and right inside the gas shell, squeezing the gas into the interior of the circular block and spraying it out along with the liquid. Under the high pressure of the liquid flow rate, the gas is mixed in, which can effectively improve the atomization effect and thus improve the dust reduction efficiency.

[0019] (4) Under the action of centrifugal force, the gravity block moves away from the circular block, and at the same time the second spring is stretched. The gravity block drives the rectangular rod to move, and the rectangular rod drives the baffle to move, so that the moving block can move down. When the work is finished, the circular block stops rotating. At this time, the rectangular rod is reset under the action of the second spring, so that the baffle is reset and blocks the lower end of the circular block, further protecting the lower end of the circular block from being contaminated and ensuring the dust reduction effect.

[0020] (5) By setting up arc-shaped blocks, protrusions and coil springs, the horizontal pipe swings back and forth during atomization, which can further increase the spraying area and improve the dust reduction effect. Attached Figure Description

Detailed Implementation

[0023] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 8 An adaptive dust suppression device for online monitoring of coal mining dust includes a support frame 5, with a conveyor belt 1 fixedly connected to the upper end of the support frame 5. After coal is mined, it is placed on the upper end of the conveyor belt 1, which is used to transfer the coal after mining. A dust suppression component is provided at the upper end of the support frame 5 to remove coal dust from the air. A support rod 2 is provided at the upper end of the support frame 5, with a fan 3 fixedly connected to the upper end of the support rod 2. The fan 3 can generate a downward airflow, allowing the liquid to better contact the dust, thereby improving the dust suppression effect. The dust suppression assembly includes a horizontal pipe 7 mounted on the upper end of a support frame 5. A liquid pipe 9 is fixedly connected to the left side of the horizontal pipe 7 for transporting liquid. A motor 6 is fixedly connected to the left side of the support frame 5, serving as a drive device. In the prior art, a reciprocating lead screw 12 is fixedly connected to the output end of the motor 6, enabling the motor 6 to drive the reciprocating lead screw 12 to rotate. A lead screw nut 13 is engaged with the wall of the reciprocating lead screw 12, matching the reciprocating lead screw 12. When the reciprocating lead screw 12 rotates, the lead screw nut 13 moves left and right. A moving tube 10 is fixedly connected to the outer side of the lead screw nut 13, enabling the lead screw nut 13 to drive the moving tube 10 to reciprocate left and right. The lower end of the moving tube 10 is rotatably connected to a circular block 14, and a gear 15 is fixedly connected to the outer side of the circular block 14. The movement of the circular block 14 drives the gear 15 to move. Rectangular openings 41 are provided on both sides of the lower end of the horizontal tube 7. A toothed block 16 is fixedly connected to the rear end of the rectangular opening 41. The toothed block 16 meshes with the outer side of the gear 15. The movement of the gear 15 is rotated under the action of the toothed block 16, which in turn causes the circular block 14 to rotate. A shrink spray assembly is provided inside the circular block 14. The outer side of the moving tube 10 is tightly fitted with the inner wall of the horizontal tube 7, and sealing rings are provided on both sides of the moving tube 10. When the moving tube 10 moves, it is always in a sealed state with the horizontal tube 7. When dust suppression is required, liquid is supplied to the interior of the horizontal pipe 7 through the liquid pipe 9. Then, the motor 6 is started, and the output end of the motor 6 drives the reciprocating screw 12 to rotate. The rotation of the reciprocating screw 12 causes the screw nut 13 to move. The screw nut 13 drives the moving pipe 10 to move. The movement of the moving pipe 10 drives the circular block 14 to move. The circular block 14 drives the gear 15 to move. Under the action of the toothed block 16, the gear 15 rotates, which in turn drives the circular block 14 to rotate. In this way, when dust suppression is performed, the moving pipe 10 is continuously moved left and right by the motor 6, and the circular block 14 is rotated by the gear 15 and the toothed block 16. Thus, when dust suppression is performed, the area of ​​liquid spraying is more uniform and wider, thereby improving the dust suppression effect.

[0025] like Figure 2 , Figure 3 and Figure 6As shown, the shrink spray assembly includes a movable block 26 slidably connected inside the circular block 14. The movable block 26 can move up and down relative to the circular block 14. Small holes 27 are evenly distributed inside the movable block 26. The small holes 27 are used for water flow. The small holes 27 have a small diameter and are sprayed with water under high pressure. The high speed causes the water to tear and atomize. A support block 23 is fixedly connected to the upper end inside the circular block 14. Water holes 24 are evenly distributed inside the support block 23. A square rod 22 is slidably connected inside the support block 23. The square rod 22 can move up and down relative to the support block 23. The lower end of the square rod 22 is fixedly connected to the upper end of the movable block 26. The square rod 22 can limit its position. So when the circular block 14 rotates, the square rod 22 causes the movable block 26 to rotate, thereby spraying evenly. A first spring 25 is fixedly connected to the lower end of the support block 23. The first spring 25 has an upward pulling force on the movable block 26. When dust suppression is needed, the water pressure inside the horizontal pipe 7 increases. Under the action of water pressure, the moving block 26 moves downward. When the moving block 26 moves downward, it drives the square rod 22 to move downward, and at the same time stretches the first spring 25. When the moving block 26 moves downward, the lower end of the small hole 27 is exposed to the outside, thereby realizing spray dust suppression. When the work is finished, the moving block 26 is pulled into the interior of the circular block 14 under the action of the first spring 25. This can effectively prevent the moving block 26 from being exposed to the air for a long time, and prevent dust from adhering to the outside of the moving block 26 and affecting the atomization effect. Furthermore, when the moving block 26 is retracted into the lower end of the circular block 14, the lower end of the circular block 14 has a pushing effect on the dirt on the outside of the moving block 26, thereby ensuring that there is no dust on the outside of the moving block 26, which is conducive to long-term use and ensures the effectiveness of the spray.

[0026] like Figure 2 and Figure 5 As shown, a gas shell 11 is fixedly connected to the lower end of the horizontal tube 7. A piston block 19 is slidably connected inside the gas shell 11. The piston block 19 can move left and right inside the gas shell 11. A support tube 18 is fixedly connected to one side of the piston block 19. The support tube 18 drives the piston block 19 to move. A circular shell 17 is rotatably connected to the outside of the circular block 14. The circular shell 17 can rotate relative to the circular block 14. A plurality of ventilation holes 35 communicating with the circular shell 17 are evenly opened on the circular block 14. A first one-way valve 33 is fixedly connected to one side of the support tube 18. A second one-way valve 21 is fixedly connected to one side of the gas shell 11. The gas shell 11 is distributed on both sides of the rectangular opening 41. A ventilation groove 20 is opened on one side of the gas shell 11 to prevent the movement of the piston block 19 from being affected by the air pressure at one end of the gas shell 11. When the circular block 14 moves left and right, it drives the circular shell 17 to move. The circular shell 17 drives the fixedly connected support tube 18 to move. The support tube 18 drives the corresponding piston block 19 to move inside the gas shell 11. Taking the leftmost gas shell 11 as an example, when the circular block 14 moves to the right, the support tube 18 drives the piston block 19 to move to the right. At this time, the first one-way valve 33 is in the closed state and the second one-way valve 21 is in the open state, thus allowing external gas to enter the gas shell 11. When the circular block 14 moves to the left, the support tube 18 drives the piston block 19 to move to the left. At this time, the first one-way valve 33 is in the open state and the second one-way valve 21 is in the closed state, thus squeezing the gas inside the gas shell 11 into the circular shell 17. Then, through the vent 35, the gas enters the circular block 14 and is sprayed out along with the liquid. Under the high pressure liquid flow rate, the gas is mixed in, which can effectively improve the atomization effect and thus improve the dust reduction efficiency.

[0027] like Figure 6 and Figure 8 As shown, a support ring 28 is fixedly connected to the lower outer end of the circular block 14. A rectangular rod 31 is slidably connected to both sides of the support ring 28. The rectangular rod 31 can move relative to the support ring 28. A baffle 30 is fixedly connected to one side of the rectangular rod 31. The baffle 30 is located at the lower end of the circular block 14. A second spring 32 is sleeved on the rod wall of the rectangular rod 31. A gravity block 29 is fixedly connected to the other side of the rectangular rod 31. One end of the second spring 32 is connected to the support ring 28, and the other end is fixedly connected to the gravity block 29. When dust suppression is in progress, the circular block 14 drives the support ring 28 to rotate, and the support ring 28 drives the rectangular rod 31 to move. At this time, under the action of centrifugal force, the gravity block 29 moves away from the circular block 14, and at the same time, the second spring 32 is stretched. The gravity block 29 drives the rectangular rod 31 to move, and the rectangular rod 31 drives the baffle 30 to move, thereby allowing the moving block 26 to move down. When the work is finished, the circular block 14 stops rotating. At this time, the rectangular rod 31 returns to its original position under the action of the second spring 32, thereby causing the baffle 30 to return to its original position and block the lower end of the circular block 14, further protecting the lower end of the circular block 14 from contamination and ensuring the dust suppression effect. When stationary, the upper end of the baffle 30 is in contact with the lower end of the circular block 14.

[0028] like Figure 4As shown, the right side of the horizontal tube 7 is fixedly connected to the housing 36. The upper end of the housing 36 is provided with a groove 37. A protrusion 38 is slidably connected inside the groove 37. The protrusion 38 moves inside the groove 37. The upper end of the protrusion 38 is fixedly connected to a third spring 39. The third spring 39 provides support to the protrusion 38. The upper end of the third spring 39 is fixedly connected to the inner wall of the groove 37. An arc-shaped block 40 is fixedly connected to the right side of the reciprocating screw 12. The rotation of the reciprocating screw 12 drives the arc-shaped block 40 to rotate. A hollow block 42 is fixedly connected to the left side of the support frame 5. A coil spring 34 is fixedly connected inside the hollow block 42. The coil spring 34 has a certain rotational force, which can ensure that the horizontal tube 7 is in a stable state when it is not subjected to external force. One side of the coil spring 34 is fixedly connected to the right side of the housing 36. The left side of the hollow block 42 is rotatably connected to the housing 36. The horizontal tube 7 and the support frame 5 are rotatably connected. The left side is connected to the support frame 5 through multiple connecting rods 8. A rotating block that is rotatably connected to the support frame 5 is provided on the left side of the multiple connecting rods 8. The reciprocating screw 12 rotates, causing the arc block 40 to rotate. The arc block 40 contacts the protrusion 38, causing the protrusion 38 to move synchronously. The protrusion 38 drives the housing 36 to move, which in turn causes the horizontal tube 7 to rotate. When the housing 36 rotates, the coil spring 34 deforms, causing resistance to the rotation of the housing 36. At this time, the arc block 40 pushes the protrusion 38 into the interior of the groove 37, compressing the third spring 39. When the arc block 40 and the protrusion 38 are misaligned, the housing 36 returns to its original position under the action of the coil spring 34. Thus, under the action of the reciprocating screw 12 and the coil spring 34, the horizontal tube 7 can swing back and forth during atomization, which can further increase the spraying area and improve the dust suppression effect.

[0029] like Figure 1 As shown, dust detection devices 4 are fixedly connected to both sides of the support frame 5. The dust detection devices 4 are electrically connected to the motor 6, and the dust detection devices 4 can control the start and stop of the motor 6. The dust detection devices 4 detect the dust concentration in the air. When the concentration reaches a certain level, the motor 6 is started, and the external water pump is controlled to supply water.

[0030] Working principle: When dust suppression is required, liquid is supplied to the interior of the horizontal pipe 7 through the liquid pipe 9. Then, the motor 6 is started. The output end of the motor 6 drives the reciprocating screw 12 to rotate. The rotation of the reciprocating screw 12 causes the screw nut 13 to move. The screw nut 13 drives the moving pipe 10 to move. The movement of the moving pipe 10 drives the circular block 14 to move. The circular block 14 drives the gear 15 to move. Under the action of the toothed block 16, the gear 15 rotates, which in turn drives the circular block 14 to rotate. In this way, when dust suppression is performed, the moving pipe 10 is continuously moved left and right by the motor 6, and the circular block 14 is rotated by the gear 15 and the toothed block 16. Thus, when dust suppression is performed, the area of ​​liquid spraying is more uniform and wider, thereby improving the dust suppression effect. Furthermore, when dust suppression is required, the water pressure inside the horizontal pipe 7 increases. Under the action of water pressure, the moving block 26 moves downward. When the moving block 26 moves downward, it drives the square rod 22 to move downward, and at the same time stretches the first spring 25. When the moving block 26 moves downward, the lower end of the small hole 27 is exposed to the outside, thereby realizing spray dust suppression. When the work is finished, the moving block 26 is pulled into the interior of the round block 14 under the action of the first spring 25. This can effectively prevent the moving block 26 from being exposed to the air for a long time, and prevent dust from adhering to the outside of the moving block 26 and affecting the atomization effect. When the moving block 26 is retracted into the lower end of the round block 14, the lower end of the round block 14 has a pushing effect on the dirt on the outside of the moving block 26, thereby ensuring that there is no dust on the outside of the moving block 26, which is conducive to long-term use and ensures the effectiveness of the spray. Furthermore, when the circular block 14 moves left and right, it drives the circular shell 17 to move. The circular shell 17 drives the fixedly connected support tube 18 to move. The support tube 18 drives the corresponding piston block 19 to move inside the gas shell 11. Taking the leftmost gas shell 11 as an example, when the circular block 14 moves to the right, the support tube 18 drives the piston block 19 to move to the right. At this time, the first one-way valve 33 is in the closed state and the second one-way valve 21 is in the open state, thus allowing external gas to enter the interior of the gas shell 11. When the circular block 14 moves to the left, the support tube 18 drives the piston block 19 to move to the left. At this time, the first one-way valve 33 is in the open state and the second one-way valve 21 is in the closed state, thus squeezing the gas inside the gas shell 11 into the interior of the circular shell 17. Then, through the vent 35, the gas enters the interior of the circular block 14 and is sprayed out along with the liquid. Under the high pressure liquid flow rate, the gas is mixed in, which can effectively improve the atomization effect and thus improve the dust reduction efficiency. Furthermore, during dust suppression, the circular block 14 drives the support ring 28 to rotate, and the support ring 28 drives the rectangular rod 31 to move. At this time, under the action of centrifugal force, the gravity block 29 moves away from the circular block 14, and at the same time, the second spring 32 is stretched. The gravity block 29 drives the rectangular rod 31 to move, and the rectangular rod 31 drives the baffle 30 to move, thereby allowing the moving block 26 to move down. When the work is finished, the circular block 14 stops rotating. At this time, the rectangular rod 31 resets under the action of the second spring 32, thereby causing the baffle 30 to reset and block the lower end of the circular block 14, further protecting the lower end of the circular block 14 from contamination and ensuring the dust suppression effect. Furthermore, the reciprocating screw 12 rotates, causing the arc block 40 to rotate. The arc block 40 contacts the protrusion 38, causing the protrusion 38 to move synchronously. The protrusion 38 drives the housing 36 to move, which in turn causes the horizontal tube 7 to rotate. When the housing 36 rotates, the coil spring 34 deforms, causing resistance to the rotation of the housing 36. At this time, the arc block 40 pushes the protrusion 38 into the interior of the groove 37, compressing the third spring 39. When the arc block 40 and the protrusion 38 are misaligned, the housing 36 is reset under the action of the coil spring 34. Thus, under the action of the reciprocating screw 12 and the coil spring 34, the horizontal tube 7 can swing back and forth during atomization, which can further increase the spraying area and improve the dust suppression effect.
