Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of coal mine dust removal, and particularly relates to a coal mine underground spray dust removal device. BACKGROUND

[0002] The dust removal work for coal dust is an essential link for the production of coal mine underground operation. If working in a coal dust polluted place for a long time, it will seriously endanger human health, cause pneumoconiosis and skin diseases. Moreover, coal dust can accelerate mechanical wear, shorten the service life of precision instruments, reduce the visibility of the operation point, and under certain conditions, when the coal dust concentration is high, it is easy to cause coal dust explosion accidents, causing huge economic losses and seriously threatening the efficient and safe production of enterprises.

[0003] The existing coal mine spray dust removal device mainly removes dust in the mine roadway by pumping water from the water tank through the water pump and spraying water mist through the spray pipe. However, the spray range of most spray dust removal devices is difficult to cover the entire roadway width. Moreover, since the width and height of the entire coal mine roadway are not uniform in size, the existing coal mine spray dust removal device cannot timely adjust the water mist spray range according to the internal structure of the coal mine roadway, affecting the dust removal effect. In addition, the existing coal mine spray dust removal device cannot timely adjust the water mist spray amount according to the size of the coal dust concentration in the roadway, which easily causes waste of water resources, and it is difficult to clean the coal dust adhered to the spray head in time, which easily causes the spray head to be blocked.

[0044] Working principle and working process:

[0045] In specific use, first, the guide frame 1 is installed on the upper wall of the mine roadway, the alarm threshold of the coal dust concentration sensor 19 is set, and the side roof 8 and the sliding connecting rod 17 are self-adaptively elongated according to the height of the roadway. The weight of the telescopic slide mechanism 2 and the swing type elastic spray assembly 5 is mainly borne by the guide frame 1. At this time, under the elastic action of the spring, the telescopic rod 7 pushes the side roof 8 to be attached to the side wall of the roadway, and the beads 9 are supported on the side wall of the roadway.

[0046] The motor is started, the driving wheel 15 is rotated, the dust collection power assembly 3 is driven to move in the roadway, and the device as a whole is driven to move. The guide wheel 11 rotates in the guide frame 1 and controls the moving direction. When the width of the passing roadway becomes narrow, the side wall of the roadway extrudes the beads 9 on the side roof 8, the spring is compressed, the telescopic rod 7 is extruded into the extension rod 10 and the support box 6 by extruding the side roof 8, and under the driving of the side roof 8, the symmetrical dust collection power assembly 3 approaches the inside, the overall width of the device is reduced, and part of the extension spray frame 36 is extruded and slid into the main spray frame 29. Similarly, when the width of the roadway becomes wide, under the elastic action of the spring, the device as a whole becomes wide to adapt to the width of the roadway. When the height of the passing roadway changes, the guide frame 1 lifts the telescopic slide mechanism 2 as a whole, the sliding connecting rod 17 is self-adaptively slid in the side roof 8, and the technical effect that the overall size of the device can be timely self-adaptively adjusted according to the internal size of the roadway is realized.

[0047] The air suction pump 24 works to suck the air containing coal dust in the roadway to assist dust reduction. The large particles of coal ash are intercepted by the filter plate 20. When the driving wheel 15 rotates, the driving block 23 is driven to rotate, and then the driving block 23 continuously drives one end of the driving rod 22 to move. By using the principle of lever, the other end of the driving rod 22 drives the filter plate 20 to move in the track of the limiting arc groove 21. The filter plate 20 continuously rotates in a small range at the opening of the dust collection box 13, and then the large particles of coal dust on the filter plate 20 are shaken off to avoid the blockage of the filter plate 20. The coal dust falls into the dust falling frame 14, and the coal dust concentration sensor 19 detects the coal dust concentration at the place where the device is located in real time.

[0048] Meanwhile, the swing motor 26 is started, so that the swing frame 25 drives the self-raking type spraying mechanism 27 and the follow-up type spraying mechanism 28 to swing integrally, the extension spray frame 36 moves in the guide frame 12, the guide frame 12 drives the extension spray frame 36 to adjust the spraying range of the main spray frame 29 and the extension spray frame 36, so that the water mist spraying range can be adjusted adaptively according to the width of the roadway; the water pump 30 sucks the water in the water tank 4 into the main spray frame 29 and the extension spray frame 36, and sprays out through the main spray head 32 and the extension spray opening 37; the width of the main spray frame 29 and the extension spray frame 36 adapts to the width of the roadway; when the extension spray opening 37 slides into the main spray frame 29 along the extension spray frame 36, the extension spray opening 37 passes through the end of the main spray frame 29, the side wall of the main spray frame 29 extrudes the blocking ball 38, so that the blocking ball 38 is embedded into the inside of the extension spray opening 37, and then the extension spray opening 37 is blocked; when the extension spray opening 37 slides out of the main spray frame 29, the extension spray opening 37 is opened under the impact of water pressure and the gravity of the blocking ball 38; the limiting rod 39 prevents the blocking ball 38 from falling; the sprayed water mist can effectively cover the whole width of the roadway, and the dust removal effect is improved; in this process, the electromagnetic ring 34 is intermittently powered, the magnetic poles of the electromagnetic ring 34 are different from those of the shaking magnetic ring 35, so that when the electromagnetic ring 34 is powered to generate magnetism, the shaking magnetic ring 35 is adsorbed, and the shaking spray head 33 is lifted to shrink and slide into the main spray head 32; when the electromagnetic ring 34 is powered off to demagnetize, the shaking spray head 33 slides out of the main spray head 32 under the gravity of the shaking spray head 33 and the impact of water flow; in the process of sliding of the shaking spray head 33, the coal dust adhered to the spray openings of the main spray head 32 and the shaking spray head 33 can be removed, so that the shaking spray head 33 is not blocked and the spraying effect is not affected.

[0049] In the process of moving spraying and dust removal of the whole device, the coal dust concentration sensor 19 detects the coal dust concentration in the roadway in real time; when the coal dust concentration is small, the electric switch is closed, the side spray head 31 does not work, and the power-on interval of the electromagnetic ring 34 is increased to save water and electricity; when the coal dust concentration is too large, the electric switch is opened, the side spray head 31 works synchronously, the water mist spraying amount and spraying range are increased, and the power-on interval of the electromagnetic ring 34 is shortened to avoid the accumulation of a large amount of coal dust and improve the efficiency of spraying and dust removal.

[0050] Synchronously, the water tank 4 moves with the water pump 40 working, the water in the roadway is recovered through the suction frame 42 and the liquid collecting pipe 41, and the coal ash in the water is filtered through the screen filter 43; in the process of moving with the water tank 4, the screen filter 43 is continuously shaken to shake off the coal ash, so that the filtering effect is not affected by the blockage.

[0051] It is worth noting that filter cotton and other auxiliary filtering materials can be added in the liquid collecting pipe 41 to increase the cleanliness of the recovered water body, which is a prior art and will not be described here.

[0052] The above is the working process of the whole device, and the next use can repeat the steps.
