Description

Technical Field

[0001] The invention relates to the technical field of coal mining, in particular to a wind and water linkage spray dust reduction device in a coal mining process. Background Art

[0002] During the coal mining process, a large amount of dust is generated. The usual protection method is to use water spraying and atomization to reduce the dust.

[0003] After searching, the Chinese patent with the announcement number CN217152012U discloses a wind and water linkage spray device for the coal mining process. By setting a water inlet pipe, a water network and a high-pressure air duct, water passes through the water network from the water inlet pipe, is atomized under the action of the air in the high-pressure air duct, and enters the fog storage box along the fog outlet hole. Then, under the action of air pressure, it enters the inner cavity of the spray plate from the inside of the fog storage box through the conveying pipe, and is then sprayed out from the spray head. The high-density water after atomization is used to achieve the purpose of dust reduction treatment in the coal mining process, and the dust reduction effect is strong and Compared with water spraying for dust reduction, it has the advantage of low water consumption and saves water resources. By setting a reciprocating swing mechanism, the rack is driven to move by an explosion-proof electric push rod, and the rack is engaged with the gear plate to achieve the purpose of driving the swing rod to swing, which is convenient for adjusting the direction of the spray plate and flexible for adjustment. Under the control of an external control mechanism, it can also achieve the effect of periodic reciprocating swing, further expanding the scope of spray dust reduction. By setting a lifting and positioning mechanism, the sleeve is used to slide on the surface of the swing rod to achieve the purpose of adjusting the height of the spray plate.

[0004] Based on the above search and combined with the existing technology, it was found that it is difficult to achieve dead-angle coverage of the entire working area by directly using the set spray plates and spray heads for spray dust reduction treatment. The spray intensity and range are uneven, and there are dust reduction dead angles. It cannot be adjusted according to the needs of different heights and positions, and the spray volume cannot be adjusted according to actual needs. There is a problem of water resource waste, which reduces the spray dust reduction efficiency of coal mining. Summary of the Invention

When the annular frame descends to the bottom along with the air outlet pipe, the through holes 1 and 2 of the outer tube and the inner tube gradually completely overlap to increase the amount of mist output. According to the requirements of different positions of the device, the spray amount and spray angle are accurately controlled to avoid water mist waste, improve water resource utilization, and enhance dust reduction effect.

[0021] Third: The present invention is provided with an inner tube, a mist inlet hood, a rotating rod and a stirring blade. The mist inlet hood is provided at the bottom of the inner tube. The water mist inside the mist storage barrel can more easily enter the inner tube through the mist inlet hood. The stirring blade rotates to make the water mist in the mist storage barrel more evenly distributed. The shear force generated by the rotational motion can further refine the water mist. The centrifugal force generated by the motion can prevent the water mist particles from settling and can further promote the water mist to enter the mist inlet hood, thereby improving the dust reduction effect of the wind and water linkage spray dust reduction device.

The outer wall of the bottom end of the inner tube 10 is fixedly connected to a mist inlet hood 26, and the outer walls on both sides of the rotating rod 16 are fixedly connected to a number of stirring blades 28. The stirring blades 28 are distributed in a linear array, and the positions of the stirring blades 28 and the mist inlet hood 26 are adapted. The mist inlet hood 26 is set at the bottom of the inner tube 10, and the mist inlet hood 26 is funnel-shaped. The water mist inside the mist storage barrel 4 can more easily enter the inner tube 10 through the mist inlet hood 26. When the motor 5 drives the gear 1 21 to rotate through the gear 2 27 on the rotating rod 16, it can also drive the stirring blades 28 to rotate, so that the water mist in the mist storage barrel 4 is more evenly distributed. The shear force generated by the rotational motion can further refine the water mist, and the centrifugal force generated by the motion can prevent the water mist particles from settling, and can also further promote the water mist to enter the mist inlet hood 26.

[0044] Working principle: During the coal mining process, when the wind and water linkage spray device is used for dust reduction treatment, external water is input into the water inlet pipe 2, and air is introduced into the high-pressure air pipe 3 to atomize the water. The water mist enters the bottom of the mist storage barrel 4 and is stored. At the same time, the motor 5 on the mounting frame 14 is started, and the rotating rod 16 rotates the sleeve 20 half a circle through the gear 1 21 and the gear 2 27. When the sleeve 20 rotates, it also drives the vertical pipe 9 to rotate. During the rotation of the vertical pipe 9, the top plate 6 and the two air outlet pipes 7 are driven to rotate. During the rotation of the top plate 6, the fixed connection The bottom plate 12 is in contact with the bottom plate 12, and the inclined planes 1 and 2 gradually rise. When the outlet pipe 7 rotates, the annular frame 13 and the annular plate 8 slide on the outer wall of the mist storage barrel 4. When the top plate 6 and the vertical pipe 9 drive the outlet pipe 7 to rise, the annular frame 13 also rises, driving the movable block 18 and the dust suppression nozzle 17 to rise. After the sleeve 20 rotates half a circle, the top plate 6 returns to its original position and descends to complete the lifting process. The annular frame 13 also drives the movable block 18 and the dust suppression nozzle 17 to rise and fall. The spray structure rotates with the outlet pipe 7 to make the spray more comprehensive and uniform, and the spray structure The vertical lifting further increases the spray effect. When the annular frame 13 is lifted and lowered on the outer wall of the annular plate 8, the tooth groove 32 on the outer wall of the movable block 18 is engaged with the rack 19 on the outer wall of the annular plate 8. When the annular frame 13 rises to the top along with the outlet pipe 7, the movable block 18 rotates under the action of the rack 19 to make the dust suppression nozzle 17 gradually tend to the horizontal and slightly tilt downward. At this time, when the vertical pipe 9 and the outer pipe 11 rise, the through hole 1 23 of the outer pipe 11 and the through hole 2 24 of the inner pipe 10 are staggered, and the water mist at the bottom of the mist storage barrel 4 enters the inner pipe 10 and then passes through the through hole 1 23. The output at the overlapping position with the through hole 24 enters the air outlet pipe 7, and finally enters the annular frame 13 through the jack 29, and is output through the dust reduction nozzle 17 of the movable block 18, spraying appropriate water mist to the surrounding of the device for dust reduction treatment. When the annular frame 13 descends to the bottom with the air outlet pipe 7, the through hole 1 23 and the through hole 2 24 of the outer tube 11 and the inner tube 10 gradually completely overlap to increase the mist output, and the movable block 18 drives the dust reduction nozzle 17 under the action of the rack 19 to gradually rotate and tilt upward, spraying more water mist to a farther part of the device for dust reduction treatment.

[0045] The sleeve 20 is slidably connected to the outer wall of the vertical pipe 9 through a slide rail, so that when the sleeve 20 drives the vertical pipe 9 to rotate, the vertical pipe 9 can also slide up and down inside the sleeve 20. Similarly, the inner pipe 10 also slides up and down inside the outer pipe 11. The annular frame 13 slides up and down on the outer wall of the annular plate 8 to ensure that it can be freely raised and lowered during the rotation process. The limiting pipe connected to the fixed rod 25 at the bottom of the mounting frame 14 provides limited support for the inner pipe 10, so that the inner pipe 10 can rotate freely.

[0046] A mist inlet hood 26 is provided at the bottom of the inner tube 10. The mist inlet hood 26 is funnel-shaped, so that the water mist inside the mist storage barrel 4 can more easily enter the inner tube 10 through the mist inlet hood 26. When the motor 5 drives the gear 1 21 to rotate through the gear 2 27 on the rotating rod 16, it can also drive the stirring blade 28 to rotate, so that the water mist in the mist storage barrel 4 is more evenly distributed. The shear force generated by the rotational motion can further refine the water mist, and the centrifugal force generated by the motion can prevent the water mist particles from settling, and can also further promote the water mist to enter the mist inlet hood 26.
