Description

Technical Field

[0001] This application relates to the technical field of mining equipment, and in particular to a tunneling device for mining. Background Technology

[0002] In the mining industry, tunneling machines are widely used in underground mines such as coal mines, gold mines, and copper mines. They can efficiently excavate ore and transport it to the surface for further processing. The use of tunneling machines can improve mining efficiency, reduce manpower input, and reduce the risk to personnel safety.

[0003] Currently, tunneling machines easily generate a large amount of dust in the air during operation, which not only affects the air quality at the construction site but also impacts the health of workers. Existing dust suppression methods typically involve spraying systems to reduce dust at the work site. However, water mist may affect the visibility of operators, hindering the work of personnel at the construction site and increasing the probability of accidents.

[0004] In related technologies, such as the tunneling machine with a dust removal device disclosed in publication number CN222276658U, air containing high concentrations of dust enters the dust removal box and first passes through a filter screen. A large amount of dust is filtered out by the filter screen, and large dust particles fall to the dust collection box at the bottom of the dust removal box. Air containing low concentrations of small dust particles continues to be filtered through the electrostatic precipitator. The air after filtration through the electrostatic precipitator is already clean air. Although this technical solution discloses the dust removal problem of the relevant tunneling machine, those skilled in the art should be very clear that when dealing with large-scale continuous mining, the dust removal structure of this patent takes a long time for a single dust removal, which is difficult to meet the dust removal requirements of the batch dust generated by large-scale continuous mining. Summary of the Invention

[0005] To address the problem that current dust removal structures take a long time to complete a single dust removal cycle, making it difficult to meet the dust removal requirements of large-scale continuous mining operations, this application provides a mining tunneling device.

[0006] The technical solution of the mining tunneling device provided in this application is as follows: A mining tunneling device, comprising: A dust collector is provided at the end of the tunneling machine, and a dust collection hopper is connected to the top of the dust collector. A high-speed fan is installed inside the dust collection hopper, and a cyclone separator is connected to the bottom of the dust collector. A spraying mechanism is used for atomizing dust suppression, and the spraying mechanism is located on one side of the dust collection box. The spraying mechanism includes a base, a support plate, a guide pipe and an atomizing nozzle. The base is fixed to one side of the outer wall of the dust collection box, the support plate is rotatably connected to the base, the guide pipe is fixed to the support plate, and the atomizing nozzle is located at one end of the guide pipe. A filtration mechanism is used to filter dust and continuously process dust in batches. The dust collection box is provided with an installation cavity. The filtration mechanism is disposed in the installation cavity and includes a fixed rod, a rotating frame, a baffle plate and a first filter screen. The fixed rod is fixed in the installation cavity. The rotating frame is rotatably connected to the fixed rod. The baffle plate is disposed on the rotating frame. The first filter screen is fixed in the installation cavity and located below the baffle plate.

[0007] By adopting the above technical solution, a water mist curtain is formed by atomizing nozzles in the spray mechanism. Through the adsorption principle, dust particles in the air are quickly captured, effectively reducing the dust concentration in the working area. At the same time, a filtration mechanism is set in the dust collection box, and a two-stage filtration unit is formed by the first and second filters in the filtration mechanism to intercept dust of different particle sizes. The primary filter is large particles, and the secondary filter is fine dust. The accumulated dust is automatically pushed to the outside of the box by mechanical transmission, avoiding manual cleaning and interruption of operation. A cyclone separator is added at the bottom of the dust collection box to further separate the escaped dust by using centrifugal force, thereby improving the overall dust removal efficiency. This integrated design realizes the automation of the dust removal process through multi-stage treatment of filtration-dust cleaning-cyclone, which significantly shortens the single processing time and is suitable for high-intensity continuous mining operations. Compared with traditional equipment, its dust removal efficiency is greatly improved and maintenance costs are reduced.

[0008] Optionally, the filtration mechanism further includes a driven rod, a second filter screen, and a linkage rod. A processing chamber is provided on one side of the dust collection box, and a through hole is provided between the processing chamber and the mounting chamber. The driven rod is rotatably connected inside the dust collection box and spans across the processing chamber and the mounting chamber. The second filter screen is fixed inside the processing chamber and located below the driven rod. The linkage rod is rotatably connected inside the processing chamber and located above the second filter screen.

[0009] By adopting the above technical solution, the processing chamber and the installation chamber form a series airflow channel through the through hole. The second filter screen, as a fine filtration unit, forms a gradient filtration with the pre-filter screen, which greatly improves the dust collection efficiency. At the same time, the dual-chamber design reduces the airflow speed and reduces the secondary dust re-entrainment. Furthermore, the cross-chamber connection of the driven rod realizes power transmission and space sharing. The equipment volume is greatly reduced compared to the traditional design, and the independent setting of the processing chamber facilitates the separate maintenance of the second filter screen.

[0010] Optionally, the driven rod is provided with a helical blade.

[0011] By adopting the above technical solution, the axial thrust generated by the rotation of the spiral-shaped blades is used to force dust to move along the spiral trajectory to the designated outlet, avoiding accumulation on the first filter screen. The pitch design can adjust the conveying speed and direction to meet different needs. At the same time, the spiral structure can achieve uninterrupted pushing, and the linkage structure can automatically discharge accumulated dust, significantly improving the continuity of the dust removal system. Compared with the traditional intermittent dust cleaning method, the operating efficiency is increased by more than 50%. Moreover, the spiral conveyor is not sensitive to changes in dust particle size and humidity, and is especially suitable for stable operation in high dust concentration scenarios such as mining.

[0012] Optionally, a lever is provided on the outside of the linkage rod, and a toothed groove structure is provided at the end of the lever away from the linkage rod. The linkage rod is slidably engaged in the gap of the second filter screen through the toothed groove structure.

[0013] By adopting the above technical solution, the toothed structure and the staggered snap-fit ​​design of the second filter screen gap can be used to make the baffle plate accurately inserted into the filter screen gap, ensuring that the microporous structure of the filter screen will not be damaged when the dust is peeled off. At the same time, the rotation of the baffle plate will quickly remove the dust concentrated on the second filter screen from the dust collection box, realizing continuous dust removal operation.

[0014] Optionally, the dust collection box is provided with a discharge port, and the discharge port communicates with the processing chamber.

[0015] By adopting the above technical solution, the setting of the discharge port facilitates the centralized collection of dust filtered out of the dust collector box by the staff. The through-type structure allows the filtered dust to be discharged directly through the discharge port, avoiding the problem of traditional equipment requiring shutdown for cleaning. This enables the dust removal system to operate 24 hours a day without interruption. In addition, the through-type channel allows for quick connection to the conveyor belt or dust collection vehicle, and the replacement of the dust collection container takes less time, significantly reducing the frequency of manual intervention. Compared with the non-through-type design, the maintenance efficiency is greatly improved.

[0016] Optionally, a first belt is provided between the rotating frame and the driven rod, and a second belt is provided between the driven rod and the linkage rod.

[0017] By adopting the above technical solution, a graded transmission system is formed by using a first belt to connect the fixed rod and the driven rod, and a second belt to connect the driven rod and the linkage rod. This design can buffer instantaneous load fluctuations and enable the two to move in sync. The double belt structure allows the fixed rod and the linkage rod to be arranged non-axially, which significantly reduces the lateral size of the equipment and is suitable for narrow environments.

[0018] Optionally, a limiting cylinder is coaxially fixed on the fixed rod. The limiting cylinder is located inside the rotating frame, and the outer wall of the limiting cylinder is provided with a sliding groove of an irregular structure. The wind baffle is rotatably connected to the rotating frame through a rotating rod, and an adjusting rod is fixed at one end of the rotating rod. The end of the adjusting rod away from the rotating rod is slidably engaged in the sliding groove.

[0019] By adopting the above technical solution, the sliding groove with an irregular structure allows one end of the adjusting rod to move in conjunction with the rotating frame while it rotates, and drives the wind deflector to deflect to a certain extent. When it rotates to a certain angle, it can be parallel to the direction of movement, reducing wind resistance and enabling the entire rotating frame to move in conjunction quickly.

[0020] Optionally, a baffle is provided between the dust collection box and the dust collection hopper, the baffle is inclined and one end is located above the wind deflector.

[0021] By adopting the above technical solution, the wind direction is blocked by the baffle, so that the wind can be directed to the baffle plate and drive the baffle plate and the rotating frame to rotate as a whole, so as to avoid the wind direction from contacting the baffle plate which has rotated to be parallel to the direction of movement.

[0022] Optionally, a support rod is rotatably connected to one end of the base away from the support plate, and the other end of the support rod is rotatably connected to the support plate, and the support rod is telescopic.

[0023] By adopting the above technical solution, the support plate is supported by the support rod and fixed at a certain angle, so that the atomizing nozzle can continuously and stably perform atomization dust removal. At the same time, the telescopic connection structure of the support rod allows the overall length to be adjusted according to the actual situation during use, thereby realizing the rapid adjustment of the angle of the support plate, enabling the atomizing nozzle to perform directional spray dust removal operations according to the actual situation.

[0024] Optionally, the mesh diameter of the first filter screen is larger than that of the second filter screen.

[0025] By adopting the above technical solution, the large-pore first filter screen preferentially intercepts large-particle dust, reducing the load on the second filter screen, thus greatly improving the overall filtration capacity of the system. Actual tests show that the dual-filter structure can extend the filtration cycle by 3 times, while achieving a multi-stage filtration effect for dust.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The misting mechanism uses atomizing nozzles to form a water mist curtain, which quickly captures dust particles in the air through adsorption, effectively reducing the dust concentration in the work area. 2. By installing a filtration mechanism inside the dust collection box, and forming a two-stage filtration unit through the first and second filters in the filtration mechanism, dust of different particle sizes is intercepted. The primary filter is large particles, and the secondary filter is fine dust. The accumulated dust is automatically pushed to the outside of the box through mechanical transmission, avoiding manual cleaning and interruption of operation. 3. By using a hydrocyclone added to the bottom of the dust collector, centrifugal force is used to further separate the escaped dust, thereby improving the overall dust removal efficiency. This integrated design achieves automation of the dust removal process through multi-stage treatment of filtration, cleaning and hydrocyclone, significantly shortening the single processing time. It is suitable for high-intensity continuous mining operations. Compared with traditional equipment, its dust removal efficiency is greatly improved and maintenance costs are reduced.

[0037] Reference Figure 1 and Figure 2 A mining tunneling device includes a dust collection box 1, a dust suction hopper 2, a hydrocyclone 3, a spraying mechanism 4, and a filtering mechanism 5. The dust collection box 1 is located at the end of the tunneling machine, and the dust suction hopper 2 is connected to the top of the dust collection box 1. A high-speed fan is installed inside the dust suction hopper 2. The hydrocyclone 3 is connected to the bottom of the dust collection box 1. The spraying mechanism 4 is located on one side of the dust collection box 1, and an installation cavity is provided inside the dust collection box 1. The filtering mechanism 5 is installed inside the installation cavity. The atomizing nozzles 44 in the spraying mechanism 4 form a water mist curtain, which quickly captures dust particles in the air through the adsorption principle, effectively reducing the dust concentration in the working area. At the same time, by setting up the filtering mechanism 5 inside the dust collection box 1, the filtering mechanism... The first filter screen 54 and the second filter screen 56 in the 5 form a two-stage filtration unit, which intercepts dust particles of different sizes. The primary filter filters large particles, and the secondary filter filters fine dust. The accumulated dust is automatically pushed to the outside of the box through mechanical transmission, avoiding manual cleaning and interruption of operation. A hydrocyclone 3 is added to the bottom of the dust collector 1 to use centrifugal force to further separate the escaped dust and improve the overall dust removal efficiency. This integrated design realizes the automation of the dust removal process through multi-stage treatment of filtration-cleaning-cyclone, which greatly shortens the single processing time and is suitable for high-intensity continuous mining operations. Compared with traditional equipment, its dust removal efficiency is greatly improved and the maintenance cost is reduced.

[0038] Specifically, the spraying mechanism 4 includes a base 41, a support plate 42, a guide pipe 43, and an atomizing nozzle 44. The base 41 is fixed to one side of the outer wall of the dust collection box 1, the support plate 42 is rotatably connected to the base 41, the guide pipe 43 is fixed to the support plate 42, and the atomizing nozzle 44 is located at one end of the guide pipe 43.

[0039] Reference Figure 3 and Figure 4In this embodiment of the application, the filter mechanism 5 includes a fixed rod 51, a rotating frame 52, a baffle plate 53, a first filter screen 54, a driven rod 55, a second filter screen 56, and a linkage rod 57. The fixed rod 51 is fixed in the mounting cavity, the rotating frame 52 is rotatably connected to the fixed rod 51, the baffle plate 53 is disposed on the rotating frame 52, the first filter screen 54 is fixed in the mounting cavity and located below the baffle plate 53, a processing cavity is provided on one side of the dust collector 1, a through hole is provided between the processing cavity and the mounting cavity, the driven rod 55 is rotatably connected in the dust collector 1 and spans across the processing cavity and the mounting cavity, the second filter screen 56 is fixed in the processing cavity and located below the driven rod 55, and the linkage rod 57 is rotatably connected in the processing cavity and located above the second filter screen 56.

[0040] Specifically, the processing chamber and the installation chamber form a series airflow channel through through holes. The second filter 56, as a fine filtration unit, forms a gradient filtration with the pre-filter, which greatly improves the dust collection efficiency. At the same time, the dual-chamber design reduces the airflow speed and reduces secondary dust re-entrainment. Furthermore, the cross-chamber connection of the driven rod 55 realizes power transmission and space sharing. The equipment volume is greatly reduced compared to the traditional design, and the independent setting of the processing chamber facilitates separate maintenance of the second filter 56.

[0041] In this embodiment, a spiral-shaped blade is provided on the outside of the driven rod 55. The rotation of the spiral-shaped blade generates axial thrust, which forces the dust to move along the spiral trajectory to the designated outlet, preventing it from accumulating on the first filter screen 54. The pitch design can adjust the conveying speed and direction to meet different needs. At the same time, the spiral structure can achieve uninterrupted pushing, and with the linkage structure, it can automatically discharge accumulated dust, significantly improving the continuity of the dust removal system. Compared with the traditional intermittent dust cleaning method, the operating efficiency is increased by more than 50%. Moreover, the spiral conveyor is not sensitive to changes in dust particle size and humidity, and is especially suitable for stable operation in high dust concentration scenarios such as mining.

[0042] Reference Figure 2 and Figure 3 Specifically, in this embodiment, regarding the linkage rod 57, a lever is provided on the outside of the linkage rod 57, and a toothed groove structure is provided at the end of the lever away from the linkage rod 57. The linkage rod 57 is misaligned and slidably engaged in the gap of the second filter screen 56 through the toothed groove structure. By utilizing the misaligned engagement design between the toothed groove structure and the gap of the second filter screen 56, the lever can be precisely inserted into the gap of the filter screen, ensuring that the microporous structure of the filter screen will not be damaged when the dust is peeled off. At the same time, the rotation of the lever will quickly move the dust concentrated on the second filter screen 56 out of the dust collection box 1, realizing continuous dust removal operation.

[0043] In this embodiment, the dust collector 1 is provided with a discharge port, which is connected to the processing chamber. The discharge port facilitates the collection of dust filtered out of the dust collector 1 by the staff. The through-type structure allows the filtered dust to be discharged directly through the discharge port, avoiding the problem of traditional equipment requiring shutdown for cleaning. This enables the dust removal system to operate 24 hours a day without interruption. The through-type channel allows for quick connection to the conveyor belt or dust collection vehicle, and the replacement of the dust collection container takes less time, significantly reducing the frequency of manual intervention. Compared with the non-through-type design, the maintenance efficiency is greatly improved.

[0044] Reference Figure 3 and Figure 4 A first belt 58 is provided between the rotating frame 52 and the driven rod 55, and a second belt 59 is provided between the driven rod 55 and the linkage rod 57. The first belt 58 connects the fixed rod 51 and the driven rod 55, and the second belt 59 connects the driven rod 55 and the linkage rod 57, forming a graded transmission system. This design can buffer instantaneous load fluctuations and enable the two to move synchronously. The double belt structure allows the fixed rod 51 and the linkage rod 57 to be arranged non-axially, which significantly reduces the lateral size of the equipment and is suitable for narrow environments.

[0045] In this embodiment of the application, regarding the fixed rod 51, a limiting cylinder 510 is coaxially fixed on the fixed rod 51. The limiting cylinder 510 is located inside the rotating frame 52, and the outer wall of the limiting cylinder 510 is provided with a sliding groove 511 with an irregular structure. The wind baffle 53 is rotatably connected to the rotating frame 52 through a rotating rod, and an adjusting rod 512 is fixed at one end of the rotating rod. The end of the adjusting rod 512 away from the rotating rod is slidably engaged in the sliding groove 511.

[0046] Specifically, the irregularly shaped slide groove 511 allows one end of the adjusting rod 512 to move in conjunction with the rotating frame 52 while it rotates, and drives the wind deflector 53 to deflect to a certain extent, so that when it rotates to a certain angle, it can be parallel to the direction of movement, reducing wind resistance and enabling the rotating frame 52 to move quickly in conjunction.

[0047] Reference Figure 1 and Figure 2 A baffle 6 is provided between the dust collection box 1 and the dust collection hopper 2. The baffle 6 is inclined and one end is located above the wind deflector 53. The baffle 6 is used to block the wind direction so that the wind can be directed to the wind deflector 53 and push the wind deflector 53 and the rotating frame 52 to rotate as a whole, so as to prevent the wind direction from contacting the wind deflector 53 which is rotated to be parallel to the direction of movement.

[0048] Reference Figure 5 and Figure 6A support rod 45 is rotatably connected to one end of the base 41 away from the support plate 42. The other end of the support rod 45 is rotatably connected to the support plate 42, and the support rod 45 is telescopic. The support rod 45 supports the support plate 42 and fixes it at a certain angle, so that the atomizing nozzle 44 can continuously and stably perform atomization dust removal. At the same time, the telescopic connection structure of the support rod 45 allows its overall length to be adjusted according to the actual situation during use, thereby realizing the rapid adjustment of the angle of the support plate 42, so that the atomizing nozzle 44 can perform directional spray dust removal operation according to the actual situation.

[0049] Reference Figure 3 Specifically, the mesh diameter of the first filter 54 is larger than that of the second filter 56. The large-diameter first filter 54 preferentially intercepts large-particle dust, reducing the load on the second filter 56 and greatly improving the overall filtration capacity of the system. Actual tests show that the dual-filter structure can extend the filtration cycle by 3 times, while achieving a multi-stage filtration effect for dust.

[0050] The implementation principle of a mining tunneling device according to an embodiment of this application is as follows: First, the entire device is fixed at the end of the tunneling machine. When the tunneling machine is operating, the liquid is guided by the guide pipe 43 and sprayed out through the atomizing nozzle 44 for initial dust suppression. At the same time, the high-speed fan in the dust collection hopper 2 is started, sucking the dust and mist into the dust collection box 1. The airflow first contacts the baffle 6 and pushes the rotating frame 52 to rotate. At this time, the dust hits the first filter screen 54, achieving initial filtration of the dust. At the same time, the first belt 58 drives the driven rod 55 to rotate, and the filtered dust is moved to the second filter screen 56 by the propeller blade. At this time, the second belt 59 drives the linkage rod 57 to rotate, and the dust is moved out of the dust collection box 1 by the deflector on the linkage rod 57. The filtered dust enters the hydrocyclone 3, and secondary filtration is achieved under the action of centrifugal force of different particle sizes.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
