Description

Technical Field

[0001] The present invention relates to the technical field of coal mining, in particular to a drilling hole device used in underground coal mines. Background Art

[0002] A drilling orifice device refers to a device that treats the opening of a borehole, such as a blowout prevention device. Chinese invention patent application number 202510239854.3 provides a pneumatic automatic slag removal and dust removal blowout prevention device, Chinese utility model patent application number 202421042347.8 provides a drilling blowout device, and Chinese utility model patent application number 202420685717.3 provides a drilling blowout device for gas management. When these three blowout prevention devices treat the mixture of debris and liquid produced in the borehole, they are unable to immediately separate the solid and liquid after discharge from the orifice. Instead, they must be aggregated before separation, resulting in low separation efficiency.

The left part of the main support frame 1 is fixed with a docking tube 2 in the left and right directions, and there is a gap between the left part and the upper and lower parts of the docking tube 2. The left part of the main support frame 1 is rotatably connected to the guide tube 3. The right part of the main support frame 1 is equipped with a seal 4 that is sealed with a drill rod of an external drilling rig. The guide tube 3 is used for axially sliding connection with the drill rod of an external drilling rig. The seal 4 can move and rotate axially compared to the drill rod of an external drilling rig. The main support frame 1 is externally rotatably connected to a No. 1 rotating tube 5. The No. 1 rotating tube 5 is a cone-shaped cone with a small left part and a large right part. The middle part of the No. 1 rotating tube 5 is circular. The circumference is radially penetrated by dense coarse sieve holes 6, and a plurality of No. 1 partitions 7 are fixed at equal angles on the circumference of the inner wall, and each No. 1 partition 7 is set at an acute angle to the virtual axis of the No. 1 rotating cylinder 5. The front or rear of the main support frame 1 is fixed with a main discharge trough 8 set along the left and right directions. The left part of the main discharge trough 8 is closed and the right part is penetrated, and the notch is set upward. The No. 1 rotating cylinder 5 is driven by a rotating drive mechanism to rotate, and the tangential direction of the rotation direction of the part close to the main discharge trough 8 is upward. The No. 1 rotating cylinder 5 is provided with an enclosing collection part on the outside, and there is a gap between the collection part and the middle part of the No. 1 rotating cylinder 5 for collecting liquid and gas. The electronic control system is externally powered, and the electronic control system 11 is a known prior art, such as a single-chip microcomputer and a PLC. The seal 4 is a known prior art, such as a packing sealing technology.

[0026] During use, the opening position of the hole drilled by the drilling rig is expanded so that the docking tube 2 can be inserted into it, and then the main support frame 1 is limited, and the drill rod is inserted into the seal 4 and the guide tube 3, and the drill rod is sealed with the seal 4. As the drill rod and the drill bit rotate (possibly accompanied by water injection), the solid-liquid mixture in the hole gradually flows out from the hole mouth position and enters the No. 1 rotating cylinder 5 along the gap between the main support frame 1 and the docking tube 2. As the rotating drive mechanism drives the No. 1 rotating cylinder 5, the No. 1 rotating cylinder 5 can screen the solid-liquid mixture, so that large pieces of solids remain in the No. 1 rotating cylinder 5 and gradually move upward with the drag of the No. 1 partition 7 until they fall into the main discharge trough 8 and wait to be discharged, while small pieces of solids and liquids are discharged through the coarse screen holes 6 and enter the collection part to be collected, thereby realizing solid-liquid separation.

The left part of the main support frame 1 is fixed with an annular left baffle 12, and the right part is fixed with an annular right baffle 13. The No. 1 rotating cylinder 5 is simultaneously connected to the docking cylinder 2, the left baffle 12 and the right baffle 13 on the same axis, and the left baffle 12 and the right baffle 13 rotate together. It is connected to the No. 2 rotating cylinder 14, which is a frustum with a small left part and a large right part, and a dense fine sieve hole 15 is radially penetrated in the central circumference. A plurality of No. 2 partitions 16 are fixed at equal angles on the inner wall of the No. 2 rotating cylinder 14. Each of the No. 2 partitions 16 and the virtual axis of the No. 2 rotating cylinder 14 is set at an acute angle. The left baffle 12 and the right baffle 13 are jointly fixed with a secondary discharge trough 17 set in the left and right directions.

The collection shell 18 is a cone-shaped collection shell with a small left part and a large right part, and a plurality of No. 3 partitions 19 are fixed at equal angles on the inner wall circumference. Each of the No. 3 partitions 19 and the virtual axis of the collection shell 18 is set at an acute angle. The right circumference of the collection shell 18 is penetrated by a plurality of discharge ports 20 at equal angles on the left and right, and the right The right baffle 13 is coaxially connected to the opening baffle 21, and the collection shell 18 is driven to rotate by the rotary drive mechanism, and when rotating, different discharge ports 20 can be connected to the openings of the opening baffle 21.

The right end of the right baffle 13 is fixedly connected to an exhaust pipe 23, and the exhaust pipe 23 is connected to the external gas collection device.

[0028] Furthermore, the No. 2 rotating drum 14 and the collecting shell 18 are driven to rotate by the rotary drive mechanism, and the solid-liquid mixture entering the collecting part is first screened by the No. 2 rotating drum 14, wherein the larger solids are intercepted and dragged upward along with the circumferentially moving No. 2 partition 16 until they fall into the auxiliary discharge trough 17 and wait to be discharged, while the fine particles of solids and liquids enter the collecting shell 18 through the fine sieve holes 15, and then flow to the right under the action of gravity and are discharged from the discharge port 20, and finally enter the sump 22. The gas and other gases generated during the drilling process can be sucked out through the exhaust pipe 23, and the opening baffle 21 is used to prevent the gas from leaking out from the upper part of the collecting shell 18.

When it falls into the main discharge trough 8 and the auxiliary discharge trough 17, it is closer to the right part of the main discharge trough 8 and the auxiliary discharge trough 17. In addition, the structure inclined to the lower right facilitates the subsequent discharge of solid waste, that is, shortens the discharge time, thereby improving the efficiency of solid-liquid separation.

[0037] The main bend 43 and the auxiliary bend 44 are fixed in sequence at the right penetration of the main discharge trough 8 and the right penetration of the auxiliary discharge trough 17. The right end of the main bend 43 is fixed with a main reduction motor 45, and the right end of the auxiliary bend 44 is fixed with an auxiliary reduction motor 46. The main reduction motor 45 and the auxiliary reduction motor 46 are electrically connected to the electric control system respectively, and are respectively arranged horizontally on the left and right. The rotating shaft of the main reduction motor 45 is inserted into the gap between the main bend 43 and the main bend 43, and the rotating shafts are aligned. The main auger 47 is fixed on the shaft, and the rotating shaft of the auxiliary reduction motor 46 is inserted into the auxiliary bend 44 through the gap, and the auxiliary auger 48 is coaxially fixed to its rotating shaft.

The shapes of the main auger 47 and the auxiliary auger 48 match the main discharge trough 8 and the auxiliary discharge trough 17 respectively.

[0038] Furthermore, by controlling the main reduction motor 45 and the auxiliary reduction motor 46 to rotate through the electronic control system, the main auger 47 and the auxiliary auger 48 can be rotated, thereby accelerating the discharge speed of solids in the main discharge trough 8 and the auxiliary discharge trough 17, thereby improving the efficiency of solid-liquid separation.

[0039] The left baffle 12 and the right baffle 13 are rotatably connected to the No. 2 support shaft 49 and the No. 4 support shaft 50, and the left baffle 12 is rotatably connected to the No. 3 support shaft 51.

The swing rod 54 and the knocking hammer 56 can both contact and disengage with the No. 2 partition 16, and the knocking rod 55 can contact the outer circumferential wall of the No. 1 rotating cylinder 5, and the knocking rod 55 always has a tendency to move downward under the action of gravity.

[0040] Furthermore, when the No. 2 rotating drum 14 rotates counterclockwise, the No. 2 partition 16 can first move the swing rod 54, thereby lifting the swing rod 54. At this time, the knocking hammer 56 is moved forward through the transmission of the No. 2 support shaft 49, the No. 3 support shaft 51, the No. 4 support shaft 50 and the No. 4 gear 52. After the No. 2 partition 16 is separated from the swing rod 54, the knocking rod 55 moves down quickly under the action of gravity, thereby knocking the No. 1 rotating drum 5 to make it vibrate. At the same time, the knocking hammer 56 is moved backward through the transmission of the No. 2 support shaft 49, the No. 3 support shaft 51, the No. 4 support shaft 50 and the No. 4 gear 52, thereby knocking the No. 2 partition 16 moving toward it, that is, the part of the No. 2 rotating drum 14 around it can be vibrated. By knocking at two places, the blocked solids are easily dropped, that is, the dredging effect is achieved without interfering with the normal screening functions of the No. 1 rotating drum 5 and the No. 2 rotating drum 14.

[0044] Furthermore, the insertion rod 60 is plugged into the inner wall of the mine where the hole is located until the contact plate 61 is in contact with the inner wall. By adjusting the position of the screw 63 relative to the screw barrel 62 using a wrench or other tool, the radial position of the ground plug 67 relative to the main support frame 1 can be adjusted until it is stably plugged into the inner wall of the mine or the ground and other supports, thereby achieving stable support and ensuring the stability of the operation of the device. Then, the screw barrel 62 is clamped using the fastening nut 64 to better limit the relative position of the screw 63, and it can be easily replaced by rotating the support barrel 66.
