Description
Technical Field
[0001] This utility model belongs to the field of dust removal technology in mining, and particularly relates to a dust removal device for large-volume directional drilling rigs in mining. Background Technology
[0002] Drilling rigs are mechanical devices used for drilling in fields such as geological exploration, construction engineering, and mining. They break rocks, soil, and other media by driving the drill bit to rotate or impact, in order to form holes of a specific diameter and depth. There are many types and functions of drilling rigs. In the process of oil extraction, rotary drilling rigs are commonly used. They use a turntable or top drive device to drive the drill rod and drill bit to rotate, breaking underground rock strata and drilling to depths of thousands of meters or even deeper.
[0003] During the drilling and mining process, there may be leaks of mine gas. Mine gas refers to the general term for various gases underground, mainly methane. In addition to methane, its components also include carbon dioxide, nitrogen, and small amounts of hydrogen sulfide, hydrogen, and rare gases. Exceeding the limit can be sudden and extremely dangerous. When the concentration in the air reaches a certain proportion, it can cause an explosion, threatening the safe production of the mine. Therefore, it is essential to detect, seal, collect, and safely discharge it in the most timely manner. Dust, including coal dust and rock dust, can also cause an explosion when it reaches a certain concentration and encounters a spark. In order to solve the above problems, there is an urgent need for dust removal devices for mining high-volume directional drilling rigs. Utility Model Content

[0008] The telescopic rod has a spring on its outer wall, and one end of the telescopic rod is fixedly connected to the dust collection box.
[0009] As a further description of the above technical solution:
[0010] A connecting ring is fixedly installed at the other end of the telescopic rod, and one end of the dust conveying pipe is fixedly connected to one end of the dust removal chamber.
[0011] As a further description of the above technical solution:
[0012] The connecting assembly includes a mounting sleeve, a clamp inside the mounting sleeve, a connecting frame fixedly mounted on the top of the clamp, a push rod rotatably mounted on the mounting sleeve through a through hole at the top, a slider slidably connected to the outer wall of the push rod, and a limit rod fixedly mounted on the outer wall of the push rod.
[0013] As a further description of the above technical solution:
[0014] A sliding plate is slidably installed inside the mounting sleeve. An extrusion block is fixedly installed on one side of the sliding plate. A connecting rod is fixedly installed on one side of the sliding plate. A connecting pipe is provided inside the mounting sleeve. The edge of one end of the connecting pipe is located between the extrusion block and the clamp.
[0015] As a further description of the above technical solution:
[0016] The connecting columns on both sides of the slider are slidably connected to the connecting frame through the slots opened in the connecting frame. The connecting rod is slidably connected to the clamp through the sliding groove opened on one side of the clamp. One end of the connecting shaft at the bottom of the clamp is fixedly connected to the inner wall of the mounting sleeve.
[0017] As a further description of the above technical solution:
[0018] The extrusion block has an inclined surface at one end, and the connecting tube extends into the interior of the mounting sleeve at one end. A sealing structure is provided between the outer wall of the connecting tube and the inner wall of the mounting sleeve. The limiting rod, push rod, and slider are provided in two sets, and the sliders of both are located at the two ends of the two push rods respectively.
[0019] As a further description of the above technical solution:

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0022] In this invention, a dust collection component is installed inside. This design enables the collection of dust during drilling through an expansion dust collection pipe and a dust collection box. Simultaneously, small dust particles are conveyed into the dust removal chamber through a dust conveying pipe and treated by water mist sprayed from a spray frame. Finally, the dust enters the dust removal module for further processing. Large dust particles are discharged into the slag discharge gas buffer box through the slag discharge pipe at the bottom of the dust collection box. When the gas concentration reaches a certain level, the operation is stopped, and the expansion dust collection pipe expands to seal the borehole and prevent gas leakage. The slag discharge port and gas extraction port of the dust removal module and the slag discharge gas buffer box are closed, thereby treating the gas through a gas treatment device.
[0023] In this invention, a connecting component is provided inside. This design allows the dust collection box to be installed by clamping and fixing the outer wall of one end of the drilling rig hydraulic rod, thus quickly fixing the dust collection box to the drilling rig hydraulic rod. Simultaneously, during the clamping process, the connecting rod moves, which in turn moves the sliding plate, causing the pressing block to gradually move and press against the end face of the connecting pipe. This ensures that the end face of the connecting pipe is in close contact with the end face of the drilling rig hydraulic rod, preventing dust and gas from leaking out from the connection between the connecting pipe and the drilling rig hydraulic rod, thereby ensuring construction safety.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0033] In its specific implementation, such as Figures 1-6 This utility model provides a technical solution: a dust removal device for a mining high-volume directional drilling rig, including a dust removal module 1, a dust removal chamber 2 fixedly installed on one side of the dust removal module 1, a spray frame 5 provided inside the dust removal chamber 2; a dust collection component 3, located at one end of the dust removal chamber 2 and connected to the dust removal chamber 2 through a pipe; and a connecting component 4, located on one side of the dust collection component 3 and connected to the pipe opening on one side of the dust collection component 3.
[0034] The dust collection assembly 3 includes a dust collection box 32, a dust conveying pipe 36 fixedly installed at the top of the dust collection box 32, an expansion dust collection pipe 31 fixedly installed on one side of the dust collection box 32, a slag discharge pipe 35 fixedly installed at the bottom of the dust collection box 32, a sliding sleeve 37 fixedly installed on the other side of the dust collection box 32, telescopic rods 34 provided on both sides of the sliding sleeve 37, a spring 33 provided on the outer wall of the telescopic rods 34, one end of the telescopic rods 34 fixedly connected to the dust collection box 32, and a connecting ring 38 fixedly installed at the other end of the telescopic rods 34, and one end of the dust conveying pipe 36 fixedly connected to one end of the dust removal chamber 2.
[0035] During mining operations after connecting the mounting sleeve 410 to the drilling rig hydraulic rod, the expansion dust collection pipe 31 is inserted into the borehole. Simultaneously, the drilling rig hydraulic rod pushes the mounting sleeve 410, causing the dust collection box 32 to contact the mine wall and compressing the spring 33 and the telescopic rod 34. This allows dust to enter the dust collection box 32 during drilling and then flow through the dust conveying pipe 36 into the dust removal chamber 2. Water mist is sprayed from the spray frame 5 inside the dust removal chamber 2 for dust removal, and finally enters the dust removal module 1. The dust removal module 1 is a known component in this technical field. This article does not elaborate too much, and large particles of debris during the drilling process can enter the slag discharge pipe 35 and the slag discharge gas buffer box connected to the slag discharge pipe 35. When the gas concentration reaches a certain level, the drilling is stopped and the slag discharge port and gas extraction port of the slag discharge gas buffer box and the dust removal module 1 are closed. At the same time, the expansion dust collection pipe 31 is expanded to seal the borehole and prevent gas leakage. The gas is treated by the gas treatment device in the slag discharge gas buffer box. The drilling operation is restarted when the concentration is reduced to a certain level.
[0036] like Figure 4 , Figure 5 , Figure 6As shown, the connecting assembly 4 includes a mounting sleeve 410, a clamp 45 inside the mounting sleeve 410, a connecting frame 44 fixedly mounted on the top of the clamp 45, a push rod 42 rotatably mounted on the mounting sleeve 410 through a through hole at the top, a slider 43 slidably connected to the outer wall of the push rod 42, a limit rod 41 fixedly mounted on the outer wall of the push rod 42, a sliding plate 48 slidably mounted inside the mounting sleeve 410, a pressing block 47 fixedly mounted on one side of the sliding plate 48, a connecting rod 49 fixedly mounted on one side of the sliding plate 48, a connecting tube 46 inside the mounting sleeve 410, one edge of the connecting tube 46 located between the pressing block 47 and the clamp 45, connecting posts on both sides of the slider 43 slidably connected to the connecting frame 44 through slots in the connecting frame 44, and the connecting rod 49 slidably connected to the clamp 45 through a through hole at one side of the clamp 45. The groove is slidably connected to the clamp 45. One end of the connecting shaft at the bottom of the clamp 45 is fixedly connected to the inner wall of the mounting sleeve 410. One end of the extrusion block 47 has an inclined surface. One end of the connecting tube 46 extends into the interior of the mounting sleeve 410, and a sealing structure is provided between the outer wall of the connecting tube 46 and the inner wall of the mounting sleeve 410. Two sets of limiting rods 41, push rods 42 and sliders 43 are provided, and the sliders 43 of both are located at the two ends of the two push rods 42 respectively. A fixing sleeve is fixedly installed on the outer wall of one end of the push rod 42, and one side of the fixing sleeve contacts the slider 43 at one end of the push rod 42. A limiting block is provided on the outer wall of the push rod 42, and grooves corresponding to the limiting block are opened on both sides of the mounting sleeve 410. One side of the mounting sleeve 410 is fixedly connected to the connecting ring 38. The mounting sleeve 410 is slidably connected to the inner wall of the sliding sleeve 37, and a sealing structure is provided between the two.
[0037] During the mining process, the drill rod is passed through the mounting sleeve 410 and the connecting pipe 46, so that one end of the mounting sleeve 410 is fitted onto one end of the drilling rig hydraulic rod. Simultaneously, the clamp 45 is positioned on the outer wall of the drilling rig hydraulic rod, and the end face of the drilling rig hydraulic rod contacts the end face of the connecting pipe 46. Then, by pushing the push rod 42 inward, the fixing sleeve on the outer wall of the push rod 42 can compress the slider 43 at one end of the push rod 42, causing the clamp 45 to be compressed and gradually tightened. This further tightens the clamp 45 and compresses and fixes it to the outer wall of the drilling rig hydraulic rod. Simultaneously, as the push rod 42 is pushed and inserted, the limiting block on the outer wall of the push rod 42 gradually extends into the mounting sleeve 410. When the clamp 45 tightens, the limiting block completely retracts. The device is inserted into the mounting sleeve 410, and by rotating the push rod 42, the limiting block is misaligned with the corresponding groove of the mounting sleeve 410. At the same time, it can drive the limiting rod 41 to rotate, so that the two limiting rods 41 contact one side and block each other. Simultaneously, the flexible protrusion on one side of the limiting rod 41 corresponds to the groove on the other side of the limiting rod 41, thereby limiting and fixing the clamp 45. During the movement of the clamp 45, the connecting rod 49 can be moved by the sliding groove on one side of the clamp 45, which in turn drives the sliding plate 48 to move. The movement of the sliding plate 48 drives the pressing block 47 to move, and the pressing block 47 presses the end face of the connecting pipe 46 so that the end face of the connecting pipe 46 can be in close contact with the end face of the drilling rig hydraulic rod, thereby completing the seal.
[0038] Working Principle: During the mining process, the drill rod is passed through the mounting sleeve 410 and the connecting pipe 46, so that one end of the mounting sleeve 410 is fitted onto one end of the drill rig hydraulic rod. Simultaneously, the clamp 45 is positioned on the outer wall of the drill rig hydraulic rod, and the end face of the drill rig hydraulic rod contacts the end face of the connecting pipe 46. Then, by pushing the push rod 42 inward, the fixing sleeve on the outer wall of the push rod 42 can compress the slider 43 at one end of the push rod 42, causing the clamp 45 to be compressed and gradually tightened. This gradually tightens the clamp 45 and compresses and fixes the outer wall of the drill rig hydraulic rod. Simultaneously, as the push rod 42 is pushed and extended, the outer wall of the push rod 42... The limiting block gradually extends into the mounting sleeve 410. When the clamp 45 tightens, the limiting block is fully retracted into the mounting sleeve 410. Rotating the push rod 42 causes the corresponding grooves of the limiting block and the mounting sleeve 410 to misalign. Simultaneously, this causes the limiting rods 41 to rotate, bringing one side of the two limiting rods 41 into contact and blocking each other. The flexible protrusion on one side of the limiting rod 41 aligns with the groove on the other side of the limiting rod 41, thus limiting and fixing the clamp 45. During the movement of the clamp 45, the sliding groove on one side of the clamp 45 drives the connecting rod 49 to move, which in turn drives the sliding plate 48 to move. The movement of the sliding plate 48 then causes compression. Block 47 moves, thereby squeezing the end face of the connecting pipe 46 through the squeezing block 47, so that the end face of the connecting pipe 46 can make tight contact with the end face of the drilling rig hydraulic rod to complete the seal. After the mounting sleeve 410 is connected to the drilling rig hydraulic rod, when mining begins, the expansion dust collection pipe 31 is inserted into the borehole. At the same time, the drilling rig hydraulic rod can push the mounting sleeve 410, causing the dust collection box 32 to contact the mine wall and compress the spring 33 and the telescopic rod 34, so that dust can enter the dust collection box 32 during the drilling process, and enter the dust removal chamber 2 through the dust conveying pipe 36. At the same time, water mist is sprayed out by the spray frame 5 inside the dust removal chamber 2 for dust removal, and finally enters the... In the dust removal module 1, which is well known in the technical field, it is not described in detail here. Large particles of debris during the drilling process can enter the slag discharge pipe 35 and the slag discharge gas buffer box connected to the slag discharge pipe 35. When the gas concentration reaches a certain level, the drilling is stopped and the slag discharge gas buffer box and the slag discharge port and gas extraction port of the dust removal module 1 are closed. At the same time, the expansion dust collection pipe 31 is expanded to seal the borehole and prevent gas leakage. The gas is treated by the gas treatment device in the slag discharge gas buffer box. The drilling operation is restarted when the concentration is reduced to a certain level.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
