Description

Technical Field

[0001] The invention relates to the technical field of mine dust removal, and in particular to a spray dust removal device for coal mine environment management. Background Art

[0002] During the mining process of coal mines, a large amount of dust is generated during the processing and crushing process, which poses potential harm to the surrounding environment and human body. Therefore, it cannot be discharged directly into the atmosphere. During the mining process of coal mines, the mining environment needs to be dusted.

[0003] At present, the spray dust removal devices used in coal mine environmental management mostly use water pumps to connect with pipelines, and then multiple atomizing nozzles are installed on the pipelines, and then water is supplied to the atomizing nozzles to generate water mist to remove dust. In the follow-up work of dust removal, it was found that since the spray pipe was installed horizontally through a fixed seat, when the spraying was completed, the water in the horizontal spray pipe, atomizing nozzle and water pump could not flow back to the water tank quickly. In severe cold weather, the spray pipe and atomizing nozzle are prone to internal freezing, resulting in the next atomization dust removal work. The dust removal device cannot be carried out due to freezing. At the same time, the freezing causes the internal volume to increase, causing damage to the pipeline, atomizing nozzle and water pump, resulting in a reduction in the service life of the dust removal device.

[0020] Beneficial effects of the present invention:

[0021] (1) During the dust removal process, water is supplied to the installation pipe, and then the water flow drives the water removal mechanism to work, so that the air bag in the water removal mechanism is automatically inflated.

[0022] (2) The bottom of the atomizing nozzle is shielded by the baffle on the nozzle protection mechanism in the protective cover. When the atomizing nozzle is in use or water is removed from the atomizing nozzle, water pressure or air pressure is generated on the fourth transmission box through the water spray pipe, thereby driving the baffle to move so that it no longer blocks the atomizing nozzle and the baffle is automatically opened, thereby realizing automatic protection of the atomizing nozzle, effectively preventing the atomizing nozzle from being blocked and damaged, and improving the stability of the dust removal device.

[0023] (3) The atomized water is collected by setting a water inlet hole on the top of the installation box, and then filtered by aligning multiple filter screens in the installation box, and then collected, so as to filter and purify the water after dust removal so that it can be reused, saving water resources. At the same time, the height of the atomizing nozzle is adjusted, so as to achieve the adjustment of different heights of the dust removal device, thereby improving the applicability of the dust removal device.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Implemented a

[0036] Water is pumped into the installation pipe 3 through the water pump 7, and then the installation pipe 3 begins to supply water to multiple water spray pipes 5. At the same time, the nozzle protection mechanism in the protective cover 4 is opened to expose the atomizing nozzle 6. Then the water spray pipe 5 sprays water mist through the atomizing nozzle 6 to spray dust and reduce dust. At the same time, the installation pipe 3 begins to push the water removal mechanism to work, so that the water removal mechanism can store energy. When the dust removal is completed, the water pump 7 stops supplying water. At this time, the water in the installation pipe 3, the atomizing nozzle 6 of the water spray pipe 5 and the water pump 7 is removed through the water removal mechanism to prevent the accumulated water inside from freezing in a cold environment, resulting in ice blockage inside the installation pipe 3, the atomizing nozzle 6 of the water spray pipe 5 and the water pump 7, which is inconvenient for next use. At the same time, the volume expansion after freezing will also damage the installation pipe 3, the water spray pipe 5, the atomizing nozzle 6 and the water pump 7, resulting in a reduced service life of the dust removal device.

The transmission control mechanism is used to control the first transmission shaft 23 to drive the second transmission shaft 25 to rotate. The outer surface of the second transmission shaft 25 is fixedly sleeved with a first bevel gear 26. The outer surface of the first bevel gear 26 meshes with the outer surface of the first bevel gear 26. A second bevel gear 27 is connected, a third transmission shaft 28 rotatably connected to the second transmission box 22 is fixedly sleeved in the middle of the second bevel gear 27, both ends of the third transmission shaft 28 are fixedly connected to a first transmission plate 29, one side of the first transmission plate 29 is rotatably connected to a second transmission plate 290, one side of the second transmission plate 290 is rotatably connected to an extrusion plate 291 slidably connected to the second transmission box 22, the top of the second transmission box 22 is fixedly connected to the air storage bag 12 through a pipeline, a one-way valve is provided on the pipeline, and one side of the second transmission box 22 is fixedly connected to an intake pipe 292, and a one-way valve is provided on the intake pipe 292;

[0040] The transmission control mechanism includes a spline shaft 31 fixedly connected to the second transmission shaft 25, a spline sleeve 32 fixedly connected to the outer surface of the spline shaft 31, a second spring 33 fixedly connected to the spline shaft 31 is fixedly connected to the top of the spline sleeve 32, a plurality of transmission columns 34 are fixedly connected to the bottom of the spline sleeve 32, a transmission groove 35 slidably connected to the transmission column 34 is opened at the top of the first transmission shaft 23, a third transmission box 36 is fixedly connected to the top of the first transmission box 21, one side of the third transmission box 36 is fixedly connected to the extrusion box 11 through a pipeline, and extrusion oil is stored in the extrusion box 11, a first transmission ring plate 37 is slidably connected to the third transmission box 36, the top of the first transmission ring plate 37 is fixedly connected to the top of the third transmission box 36, a ball is rotatably connected to the top of the top column 38, and the outer surface of the spline sleeve 32 is fixedly connected to the second transmission ring plate 39.

[0041] When spray dust removal is performed, water is supplied to the installation pipe 3 through the water pump 7. At this time, the water in the installation pipe 3 enters the water spray pipe 5 through the first transmission box 21 and the control box 13, and then spray dust removal is performed through the atomizing nozzle 6 at the bottom of the water spray pipe 5. At this time, when the water flows in the control box 13, since the through hole 15 on the transmission block 14 in the control box 13 is small, the transmission block 14 moves under the action of water pressure, and the first spring 16 is stretched to move the transmission block 14 to the bottom of the pipe connecting the air storage bag 12 and the control box 13, blocking the pipe. At the same time, the water flow drives the blade 24 to rotate during the flow in the first transmission box 21, and the blade 24 drives the first transmission shaft 23 to rotate. The first transmission shaft 23 is rotated. The transmission column 34, the spline sleeve 32 and the spline shaft 31 are driven to rotate through the transmission groove 35, the spline shaft 31 drives the second transmission shaft 25 to rotate, the second transmission shaft 25 drives the third transmission shaft 28 to rotate through the first bevel gear 26 and the second bevel gear 27, and the third transmission shaft 28 drives the extrusion plate 291 to reciprocate up and down in the second transmission box 22 through the first transmission plate 29 and the second transmission plate 290. At this time, the second transmission box 22 cooperates with the intake pipe 292 and the one-way valve. The one-way valve allows the intake pipe 292 to only intake air into the second transmission box 22, so that the second transmission box 22 inflates the air storage bag 12 through the pipeline, and the air storage bag 12 begins to bulge. At this time, the air storage bag 12 gradually increases and begins to be filled The extrusion oil in the extrusion box 11 is then squeezed in the extrusion box 11, and then the extrusion oil enters the third transmission box 36 through the pipeline and starts to squeeze the first transmission ring plate 37 in the third transmission box 36, and the first transmission ring plate 37 drives the top column 38 to move upward, and the top column 38 drives the second transmission ring plate 39 and the spline sleeve 32 to move upward, and the transmission column 34 at the bottom of the spline sleeve 32 leaves the transmission groove 35 on the first transmission shaft 23, so that the first transmission shaft 23 no longer drives the second transmission shaft 25 to rotate, and the air storage bag 12 is no longer inflated at this time, and the automatic inflation of the air storage bag 12 is completed. When the water mist dust removal is stopped, the water pump 7 stops working at this time, and the transmission block 14 in the control box 13 is no longer affected by the water pressure. At this time, the first spring 16 The pulling force drives the transmission block 14 to move to the right, and the pipe connecting the air storage bag 12 and the control box 13 is opened. At this time, the gas in the air storage bag 12 supplies air to the control box 13 through the pipe. At this time, the water in the mounting pipe 3 and the water spray pipe 5 is sprayed out through the atomizing nozzle 6 under the action of the airflow. At the same time, the water in the water pump 7 is pushed through the through hole 15 on the transmission block 14, the mounting pipe 3 and the pipe to discharge the water in the water pump 7. Therefore, after stopping the water mist dust removal, the water in the mounting pipe 3, the water spray pipe 5, the atomizing nozzle 6 and the water pump 7 is automatically discharged to prevent damage caused by internal freezing in a cold environment, or blockage caused by freezing, which makes it impossible to use the device next time, thereby greatly improving the service life and stability of use of the device.When the air storage bag 12 is shrunk, the oil is no longer squeezed. At this time, the spline sleeve drives the transmission column 34 to be inserted into the transmission groove 35 under the action of the second spring 33, so that the first transmission shaft 23 and the second transmission shaft 25 are combined, which is convenient for air storage during the next dust removal work.

[0042] Embodiment 3

[0043] Based on Example 2, please refer to Figure 3 and Figure 7 As shown, the nozzle protection mechanism protective cover 4 is fixedly connected to two fourth transmission boxes 41, and an insulation layer is arranged on the outer surface of the fourth transmission box 41 to prevent the water in the fourth transmission box 41 from freezing. The bottom of the fourth transmission box 41 is connected to the water spray pipe 5 through a pipeline, and a third transmission plate 42 is slidably connected in the fourth transmission box 41, and a transmission rod 43 slidably connected to the fourth transmission box 41 is fixedly connected to one side of the third transmission plate 42, and one end of the transmission rod 43 is fixedly connected to a baffle 44 slidably connected to the protective cover 4 through a connecting rod, and one side of the baffle 44 is fixedly connected to a third spring 45 fixedly connected to the protective cover 4.

[0044] When water mist dust removal is performed, when water is supplied to the water spray pipe 5 through the installation pipe 3, the water spray pipe 5 first supplies water into the fourth transmission box 41 through the pipeline. At this time, the third transmission plate 42 and the transmission rod 43 in the fourth transmission box 41 are driven to move under the action of water pressure. At this time, the third spring 45 is compressed, and the transmission rod 43 drives the baffle 44 to move through the connecting rod, so that the baffle 44 no longer blocks the bottom of the atomizing nozzle 6, so that the atomizing nozzle 6 can spray water mist normally downward. When the water mist dust removal is stopped, the fourth transmission plate 42 and the transmission rod 43 in the fourth transmission box 41 are driven to move. The water pressure in the moving box 41 decreases. At this time, the two baffles 44 in the protective cover 4 move under the action of the third spring 45 to cover the bottom of the atomizing nozzle 6 to prevent dust from entering the spray hole at the bottom of the atomizing nozzle 6 and clogging the atomizing hole when it is not working. At the same time, when the water removal mechanism is discharging water, the third transmission plate 42 is driven by air pressure to move to open the baffle 44, thereby realizing automatic protection of the atomizing nozzle 6, effectively preventing the atomizing nozzle 6 from being blocked and damaged, and improving the stability of the dust removal device.

[0045] Embodiment 4

[0046] Based on Example 1, please refer to Figure 1 and Figure 3 As shown, a plurality of water inlet holes 51 are opened on the top of the installation box 1, and a plurality of filter screen plates 52 are fixedly connected inside the installation box 1.

[0047] The atomized dust falls downward under the action of gravity, and then enters the installation box 1 through the water inlet hole 51 on the top of the installation box 1, and then is filtered through multiple filter screens 52 in the installation box 1. The filtered water is then collected through a pipe, thereby filtering and purifying the dust-removed water for reuse, saving water resources.

[0048] The support frame 2 includes an adjusting sleeve 61 fixedly connected to the mounting box 1, an adjusting column 62 is slidably connected inside the adjusting sleeve 61, a mounting plate 63 fixedly connected to the mounting tube 3 is fixedly connected to the top of the adjusting column 62, a plurality of adjusting holes 64 are opened on the adjusting column 62, and an outer surface of the adjusting sleeve 61 is threadedly fitted with an adjusting bolt 65 slidably connected to the adjusting hole 64.

[0049] By moving the adjustment column 62 in the adjustment sleeve 61, the adjustment column 62 drives the mounting plate 63 and the mounting tube 3 to move to a suitable height, and then the adjustment column 62 is fixed by the adjustment bolt 65 and the adjustment hole 64, so as to realize the adjustment of different heights of the dust removal device and improve the applicability of the dust removal device.

[0050] Working principle of the present invention: when spray dust removal is performed, water is supplied to the installation pipe 3 through the water pump 7, and the water in the installation pipe 3 enters the water spray pipe 5 through the first transmission box 21 and the control box 13, and then spray dust removal is performed through the atomizing nozzle 6 at the bottom of the water spray pipe 5. When the water flows in the control box 13, since the through hole 15 on the transmission block 14 in the control box 13 is small, the transmission block 14 moves under the action of water pressure, and the first spring 16 is stretched to move the transmission block 14 to the bottom of the pipe connecting the air storage bag 12 and the control box 13, blocking the pipe. At the same time, the water flow drives the blade 24 to rotate during the flow in the first transmission box 21, and the blade 24 drives the first transmission shaft 23 to rotate. The first transmission shaft 23 drives the transmission column 34, the spline sleeve 32 and the spline shaft 31 to rotate through the transmission groove 35, the spline shaft 31 drives the second transmission shaft 25 to rotate, the second transmission shaft 25 drives the third transmission shaft 28 to rotate through the first bevel gear 26 and the second bevel gear 27, the third transmission shaft 28 drives the extrusion plate 291 to reciprocate up and down in the second transmission box 22 through the first transmission plate 29 and the second transmission plate 290. At this time, the second transmission box 22 cooperates with the intake pipe 292 and the one-way valve. The one-way valve allows the intake pipe 292 to only intake air into the second transmission box 22, so that the second transmission box 22 inflates the air storage bag 12 through the pipeline, and the air storage bag 12 begins to swell. At this time, the air storage bag 12 starts to swell. The bag 12 gradually increases and begins to fill the extrusion box 11, and then squeezes the extrusion oil in the extrusion box 11, and then the extrusion oil enters the third transmission box 36 through the pipeline and begins to squeeze the first transmission ring plate 37 in the third transmission box 36, and the first transmission ring plate 37 drives the top column 38 to move upward, and the top column 38 drives the second transmission ring plate 39 and the spline sleeve 32 to move upward, and the transmission column 34 at the bottom of the spline sleeve 32 leaves the transmission groove 35 on the first transmission shaft 23, so that the first transmission shaft 23 no longer drives the second transmission shaft 25 to rotate, and the air storage bag 12 is no longer inflated. When the water mist dust removal is stopped, the water pump 7 stops working, and the transmission block 14 in the control box 13 is no longer affected by the water pressure. At this time, the first spring 16 pulls The force drives the transmission block 14 to move to the right, and the pipe connecting the air storage bag 12 and the control box 13 is opened. At this time, the gas in the air storage bag 12 supplies air to the control box 13 through the pipe. At this time, the water in the mounting pipe 3 and the water spray pipe 5 is sprayed out through the atomizing nozzle 6 under the action of the airflow. At the same time, the water in the water pump 7 is pushed through the through hole 15 on the transmission block 14, the mounting pipe 3 and the pipe to discharge the water in the water pump 7. Therefore, after stopping the water mist dust removal, the water in the mounting pipe 3, the water spray pipe 5, the atomizing nozzle 6 and the water pump 7 is automatically discharged to prevent damage caused by internal freezing in a cold environment, or blockage caused by freezing, which makes it impossible to use the device next time, thereby greatly improving the service life of the device and the stability of use.
