Description

Technical Field

[0001] This utility model belongs to the field of coal mine drilling technology, and in particular relates to a drilling blowout prevention and separation device. Background Technology

[0002] With the advancement of coal mining technology, the widespread application of techniques such as one-time full-height mining of extra-thick coal seams and fully mechanized top-coal caving, the speed of working face advancement is accelerating, and gas emissions are increasing. Previously low-gas mines are now transforming into high-gas mines. Single gas extraction methods are no longer sufficient to guarantee safe mining in high-gas mines; therefore, integrated gas extraction methods are essential for gas control in high-gas mines. Borehole extraction technology is one of the most frequently used measures in preventing gas disasters and achieving integrated extraction.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] according to Figure 1-5 As shown, this embodiment provides a drilling blowout separation device, which includes a first tank 10, a second tank 20 and an adsorption ring 30. The adsorption ring 30 is connected to the second tank 20 through a hose 31. The first tank 10 and the second tank 20 are detachably connected. After separation, the first tank 10 and the second tank 20 can be disassembled for cleaning or replacement.

[0040] The second tank 20 is equipped with a suction pipe 21 and an annular water pipe 22. The suction pipe 21 is located on the top side of the second tank 20 and is connected to a suction device to provide suction, allowing gas and coal dust to enter the second tank 20. The annular water pipe 22 is located on the inner wall of the second tank 20, surrounding the inner wall. One end of the pipe is located on the outside of the second tank 20 and connected to a water pipe, while the other end is closed, providing a water source through the water pipe. The annular water pipe 22 inside the second tank 20 is equipped with a spray hole (not shown in the figure), allowing water in the annular water pipe 22 to be sprayed out through the spray hole.

[0041] The second tank 20 is equipped with a mounting bracket (not shown in the figure), a motor 23, and a dust baffle 24. The mounting bracket is used to fix the motor 23 and the dust baffle 24. The motor 23 is located in the middle of the second tank 20. The output end of the motor 23 can extend into the first tank 10. The top of the output end is equipped with a suction fan blade 24, and the bottom of the output end is equipped with a connecting frame 12. The motor 23 can drive the suction fan blade 24 and the connecting frame 12 to rotate. By rotating the suction fan blade 24, the gas can be moved upward, further improving the separation effect of gas and coal dust.

[0042] The dust baffle 24 is positioned between the suction pipe 21 and the annular water pipe 22. Specifically, the dust baffle 24 is positioned below the suction fan blades 24 and above the annular water pipe 22. The dust baffle 24 has a through hole (not shown in the figure) in its center, allowing the output end of the motor 23 to pass through. When gas and coal dust enter the second tank 20, they are first treated with water spray. This causes the coal dust to fall freely due to its own weight, or the water carries some of the coal dust, causing it to fall freely due to its own weight. Meanwhile, the gas, being less dense than air, rises, thus separating the gas from the coal dust. The dust baffle 24 prevents gas from carrying some coal dust into the top of the second tank 20, thus preventing the gas and coal dust from being separated. A secondary separation is achieved through the dust baffle 24.

[0043] The first tank 10 is provided with a drain pipe 14 and a discharge pipe 15. Inside it is a rotating cylinder 11. The inner diameter of the rotating cylinder 11 is smaller than the inner diameter of the first tank 10, so that there is a gap between the rotating cylinder 11 and the inner wall of the first tank 10. The drain pipe 14 is provided on one side of the gap, which can discharge the water sprayed from the water spray hole through the drain pipe 14. The bottom center of the rotating cylinder 11 is provided with an insertion tube (not shown in the figure). The discharge pipe 15 is located at the bottom center of the first tank 10. The insertion tube is connected to the discharge pipe 15, and the coal dust is discharged through the discharge pipe 15.

[0044] The rotating drum 11 has a through hole (not shown in the figure) around its circumference. The rotating drum 11 is used to receive the separated coal dust and water. The through hole allows water to pass through but not coal dust. Its function is to separate the water and coal dust in the rotating drum 11 so that the water can be discharged through the drain pipe 14 and the coal dust can be discharged through the discharge pipe 14.

[0045] The connecting frame 12 is connected to the rotating drum 11, specifically as follows: The end of the connecting frame 12 is provided with an insert block 121, and the rotating drum 11 is provided with a slot 111. The connecting frame 12 and the rotating drum 11 are connected by inserting the insert block 121 into the slot 111. Then, the connecting frame 12 drives the rotating drum 11 to rotate, allowing water and coal dust to separate through the through-hole of the rotating drum 11. A pressure plate 13 is provided at the connection point between the connecting frame 12 and the motor output end. The pressure plate 13 increases the connection between the connecting frame 12 and the output end, serving to support the connecting frame 12.

[0046] Both the first tank 10 and the second tank 20 have annular rails 17 at their bottoms. The rotating drum 12 has connecting blocks 112 at its bottom and top. Annular bars 171 are located inside the annular rails 17. The connecting blocks 112 are fixed to the annular rails 17 via the annular bars 171, allowing the rotating drum 11 to rotate along the annular rails 17. The annular rails 17 can also be simultaneously located within the first tank 10, either at the top or bottom, completely housing the rotating drum 11 within the first tank 10.

[0047] The first tank 10 is provided with a first mounting ring 16 on its outer side, and the second tank 20 is provided with a second mounting ring 26 on its outer side. The first tank 10 and the second tank 20 are detachably connected to achieve a detachable connection. The connection method can be a bolt connection or a snap-fit ​​connection. When it is a bolt connection, through holes can be provided in the first mounting ring 16 and the second mounting ring 26 to allow the screw to pass through. Then, a nut is used to screw in the screw for fixation, thereby achieving a detachable connection between the first tank 10 and the second tank 20.

[0048] Bolted connections require multiple bolts for fixation, which consumes a significant amount of time during installation and disassembly. To further save time, the first mounting ring 16 and the second mounting ring 26 are improved. The first mounting ring 16 has mounting holes (not shown in the figure) with internal threads. The second mounting ring 26 is fixedly connected to a mounting block 40, which is bolted to the bottom of the second mounting ring 26. The surface of the mounting block 40 has threads that match the threads of the mounting holes. The second can 20 is placed on top of the first can 10. By rotating the second can 20 or the first can 10, the threads of the mounting block 40 engage with the threads of the mounting holes, making the first can 10 and the second can 20 detachably connected.

[0049] Because the installation and disassembly of the first tank 10 or the second tank 20 require rotation, which is inconvenient, the first mounting ring 16 and the second mounting ring 26 are further improved to facilitate installation and disassembly. The first mounting ring 16 is provided with a mounting hole, and a threaded sleeve 41 and a toothed ring 43 are provided at the bottom of the mounting hole. The mounting hole is connected to the threaded sleeve 41 and the toothed ring 43 by rotation. A gear 42 is provided on the outside of the threaded sleeve 41, and the toothed ring 43 meshes with the gear 42. The inner side of the threaded sleeve 41 is provided with threads. The second mounting ring 26 is fixedly connected to a mounting block 40. The mounting block 40 is fixed to the bottom of the second mounting ring 26 by bolts. The surface of the mounting block 40 is provided with threads that match the threads of the threaded sleeve 41. The second tank 20 is placed on top of the first tank 10, and then the toothed ring 43 is rotated to drive the threaded sleeve 41 to rotate through the gear 42, so that the threads of the threaded sleeve 41 mesh with the threads of the mounting block 40, so that the first tank 10 and the second tank 20 are detachably connected.

[0050] The working principle of the borehole blowout prevention separation device in this embodiment is as follows:

[0051] When in use, the adsorption ring 30 is fitted onto the drill rod to collect the gas and coal dust generated during drilling. The suction pipe 21 is connected to the suction equipment, which generates suction inside the second tank 20. Through the adsorption groove 32 and the adsorption hole 31, the gas and coal dust enter the interior of the second tank 20 along the hose 31. Water is sprayed out through the spray hole of the annular water pipe 22. The water and coal dust fall freely into the interior of the rotating drum 11. The motor 23 drives the suction fan blade 25 to rotate, further improving the separation effect of gas and coal dust. The connecting frame 12 drives the rotating drum 11 to rotate through the insert block 121 and the slot 111, which separates the water and coal dust inside the rotating drum 11. The water and coal dust are discharged through the drain pipe 14 and the discharge pipe 15, respectively, achieving the separation of gas and coal dust with a very good separation effect.

[0052] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
