Description

Technical Field

[0001] This invention relates to the field of coal mining technology, specifically to a high-pressure water jet dust removal device for coal mines. Background Technology

[0002] Currently, coal dust generated during coal mining operations often causes serious pollution to the working environment, affecting miners' health and the production environment. Therefore, coal mine dust removal equipment has become crucial for safe production and environmental protection in coal mines. Traditional dust removal equipment often uses static spraying or simple water spraying systems, resulting in uneven spraying and a small coverage area, making it difficult to effectively cover large working areas. Furthermore, these devices lack precise control over water flow and pressure during high-pressure water jet dust removal, leading to water waste and failing to achieve optimal dust removal results in actual operations.

[0003] Existing water jet dust suppression devices typically employ simple water spray pipes and nozzles. While they can suppress coal dust to some extent, the inability to precisely control factors such as the spray angle, flow rate, and water pressure leads to unstable dust suppression effects and makes them unsuitable for the diverse working environments of coal mines. Furthermore, many existing dust suppression systems lack dynamic adjustment capabilities, failing to automatically adjust water flow and spray coverage areas according to different working conditions in the mine. This results in insufficient or excessive water spraying in certain areas, affecting dust suppression efficiency and even increasing energy consumption and water waste.

[0004] Therefore, there is an urgent need for a new high-pressure water jet dust removal device for coal mines. Through a rationally designed water sweeping mechanism and pressure regulation function, it can improve dust removal efficiency, reduce water waste, and provide stable dust removal effect to adapt to the changing needs of the coal mining environment. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a high-pressure water jet dust removal device for coal mines to solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-pressure water jet dust removal device for coal mines includes a support leg, on which a water tank is mounted, and further includes:

[0008] A water outlet pipe is installed inside the water tank.

The water sweeping mechanism includes a mounting block, a water sweeping power component, and a water sweeping component. The mounting block is mounted on the mounting plate. One end of the mounting block is fixedly connected to the mounting plate, and the other end of the mounting block is fixedly connected to the water sweeping power component. The output end of the water sweeping power component is connected to the water sweeping component. The water sweeping component is located on one side of the water outlet pipe.

[0010] The sweeping power assembly includes a mounting base, a second guide groove, and a power component. The mounting base is fixedly connected to the mounting block. The mounting base is provided with a second guide groove, which has a cylindrical structure. The power component is provided within the second guide groove. The power component is movably connected to the second guide groove. The output end of the power component is connected to the sweeping assembly.

[0011] The water sweeping assembly includes a first rotating rod, a second rotating rod, and a water sweeping rod. The first rotating rod is connected to the output end of the power component and passes through the mounting base. The first rotating rod is movably connected to the second rotating rod. The second rotating rod is movably connected to the mounting block through a rotating pin. The second rotating rod is fixedly connected to the water sweeping rod. The first rotating rod is symmetrically arranged about the power component. The water sweeping rod is located on one side of the water outlet pipe.

[0012] When the power component is activated, it reciprocates, driving the first rotating rod, which is symmetrically arranged, to move. Because the first rotating rod is symmetrically arranged, the two first rotating rods rotate in opposite directions, and the first rotating rod drives the second rotating rod to move.

[0013] The second rotating rod is movably connected to the mounting block at one end, causing the second rotating rod to rotate. At the same time, the second rotating rod drives the sweeping rod to rotate. When the sweeping rod rotates, the other end of the sweeping rod passes through the water outlet of the water pipe in an alternating manner.

[0014] As a further embodiment of the present invention, a fixing frame is provided below the water tank, the fixing frame is fixedly connected to the bottom of the water tank, and a pressure regulating mechanism is provided inside the fixing frame, the pressure regulating mechanism being fixedly connected to the support leg.

[0015] As a further aspect of the present invention, the pressure regulating mechanism includes:

[0016] A first mounting block is fixedly connected to the support leg, and two first mounting blocks are provided;

[0017] A pressure regulating component is movably connected to the first mounting block, and its output end is connected to a pushing component. The pushing component is disposed within the fixed frame and passes through the water tank.

[0018] A speed regulating component, one end of which is fixedly connected to the fixing frame, and the other end of which is movably connected to the voltage regulating component;

[0019] A push plate is disposed on the push assembly and is movably connected to the inner wall of the water tank.

[0020] As a further aspect of the present invention, the voltage regulating component includes:

[0021] A power rotating plate, which is movably connected to the first mounting block, and the power rotating plate adopts a convex structure;

[0022] A connecting rod is connected to symmetrically arranged power rotating plates. The connecting rod is fixedly connected to the fixed connecting block. A first connecting rod is provided on the fixed connecting block. The first connecting rod is movably connected to the speed regulating component and the pushing component.

[0023] As a further embodiment of the present invention, the driving component includes:

[0024] A second connecting rod, one end of which is movably connected to the first connecting rod, and the second connecting rod is movably connected to the speed regulating component;

[0025] A fixed rotating pin is used, and the second connecting rod is connected to a fixed sleeve via the fixed rotating pin. The fixed sleeve is provided in the [location].

[0026] As a further aspect of the present invention, the speed regulating component includes:

[0027] A first guide groove, one end of which is fixedly connected to the fixing frame, the first guide groove having an arc-shaped structure;

[0028] A sliding arc-shaped block is disposed in the first guide groove, and the first guide groove is movably connected to the sliding arc-shaped block;

[0029] The third connecting rod has one end movably connected to the sliding arc-shaped block, and the other end movably connected to the second connecting rod and the first connecting rod.

[0030] As a further embodiment of the present invention, the fixing sleeve is fixedly connected to the push plate, and the fixing sleeve penetrates through the bottom of the water tank.

[0031] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art:

[0032] By designing the water-sweeping mechanism and utilizing a symmetrically rotating sweeping bar structure, the water spray coverage area of ​​the outlet pipe is significantly increased, effectively expanding the dust removal area and ensuring a more comprehensive dust removal effect. The up-and-down swinging motion of the sweeping bar also ensures that the water flow is evenly distributed, effectively avoiding the problem of uneven water spray range, thereby improving the stability and reliability of the system.

[0033] Furthermore, the pressure regulation mechanism in the water tank can dynamically adjust the water pressure as needed, thereby ensuring that the water flow rate in the outlet pipe matches the dust removal requirements, further optimizing the water flow efficiency and dust removal effect. When the water flow is insufficient, the adjustment mechanism can precisely adjust the water flow output speed by changing the position of the sliding arc block, ensuring continuous and efficient dust removal operations and improving the applicability and economy of the equipment.

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0046] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0047] In one embodiment, a high-pressure water jet dust removal device for coal mines, see [link / reference] Figures 1-9 It includes a support leg 1, on which a water tank 3 is provided, and also includes:

[0048] Water outlet pipe 7 is installed inside the water tank 3;

[0049] Mounting plate 5 is disposed on the outer wall of water tank 3. A water sweeping mechanism 6 is disposed on the mounting plate 5 and disposed on one side of water outlet pipe 7. The water sweeping mechanism 6 includes mounting block 61, water sweeping power component 62, and water sweeping component 63. Mounting block 61 is mounted on mounting plate 5. One end of mounting block 61 is fixedly connected to mounting plate 5, and the other end of mounting block 61 is fixedly connected to water sweeping power component 62. The output end of water sweeping power component 62 is connected to water sweeping component 63. Water sweeping component 63 is disposed on one side of water outlet pipe 7.

[0050] The sweeping power assembly 62 includes a mounting base 621, a second guide groove 622, and a power component 623. The mounting base 621 is fixedly connected to the mounting block 61. The second guide groove 622 is provided inside the mounting base 621. The second guide groove 622 has a cylindrical structure. The power component 623 is provided inside the second guide groove 622. The power component 623 is movably connected to the second guide groove 622. The output end of the power component 623 is connected to the sweeping assembly 63.

[0051] The water sweeping assembly 63 includes a first rotating rod 631, a second rotating rod 632, and a water sweeping rod 633. The first rotating rod 631 is connected to the output end of the power component 623 and passes through the mounting base 621. The first rotating rod 631 is movably connected to the second rotating rod 632. The second rotating rod 632 is movably connected to the mounting block 61 through a rotating pin. The second rotating rod 632 is fixedly connected to the water sweeping rod 633. The first rotating rod 631 is symmetrically arranged about the power component 623. The water sweeping rod 633 is located on one side of the water outlet pipe 7.

[0052] When the power component 623 is activated, it reciprocates. The power component 623 drives the first rotating rod 631, which is arranged in a rotationally symmetrical manner, to move. Since the first rotating rod 631 is arranged in a rotationally symmetrical manner, the two first rotating rods 631 rotate in opposite directions. The first rotating rod 631 drives the second rotating rod 632 to move.

[0053] The second rotating rod 632 is movably connected to the mounting block 61 at one end, so that the second rotating rod 632 rotates. At the same time, when the second rotating rod 632 rotates, it drives the sweeping rod 633 to rotate. When the sweeping rod 633 rotates, the other end of the sweeping rod 633 passes through the water outlet of the water outlet pipe 7 in an alternating manner.

[0054] In this embodiment, after water is placed in the water tank 3, a water outlet pipe 7 is installed in the water tank 3, and a water pump is installed on the water outlet pipe 7. At the same time, one end of the water outlet pipe 7 is located on the side of the water tank 3. When the water pump is started, the water in the water tank 3 is pumped out. At this time, the power component 623 is started, and the power component 623 performs reciprocating motion. The power component 623 drives the first rotating rod 631, which is arranged in a rotationally symmetrical manner, to move. Since the first rotating rod 631 is arranged in a rotationally symmetrical manner, the two first rotating rods 631 rotate in opposite directions. The first rotating rod 631 drives the second rotating rod 632 to move.

[0055] The second rotating rod 632 is movably connected to the mounting block 61, so that the second rotating rod 632 rotates. At the same time, when the second rotating rod 632 rotates, it drives the sweeping rod 633 to rotate. When the sweeping rod 633 rotates, the other end of the sweeping rod 633 passes through the water outlet of the water outlet pipe 7 in an alternating manner.

[0056] The sweeping rod 633 swings up and down, passing through the water outlet of the water pipe 7 during the swing, so that the sweeping rod 633 can disperse the water sprayed from the water pipe 7, increase the water spray coverage of the water pipe 7, and ensure an increase in the dust removal range. At the same time, the two sets of sweeping rods 633 can ensure a stable water outlet surface improvement effect of the water pipe 7.

[0057] In one embodiment, see Figures 1-9A fixing frame 2 is provided below the water tank 3. The fixing frame 2 is fixedly connected to the bottom of the water tank 3. A pressure regulating mechanism 4 is provided inside the fixing frame 2. The pressure regulating mechanism 4 is fixedly connected to the support leg 1.

[0058] Further, see Figures 1-9 The pressure regulating mechanism 4 includes:

[0059] First mounting block 41, the first mounting block 41 is fixedly connected to the support leg 1, and two first mounting blocks 41 are provided;

[0060] A pressure regulating component 42 is movably connected to the first mounting block 41. The output end of the pressure regulating component 42 is connected to a pushing component 43. The pushing component 43 is disposed in the fixed frame 2 and passes through the water tank 3.

[0061] Speed ​​regulating component 44, one end of which is fixedly connected to the fixing frame 2, and the other end of which is movably connected to the pressure regulating component 42;

[0062] A push plate 45 is disposed on the push assembly 43 and is movably connected to the inner wall of the water tank 3.

[0063] Further, see Figures 1-9 The voltage regulating component 42 includes:

[0064] A power rotating plate 421 is movably connected to the first mounting block 41, and the power rotating plate 421 adopts a convex structure.

[0065] A connecting rod 422 is connected to a symmetrically arranged power rotating plate 421. The connecting rod 422 is fixedly connected to a fixed connecting block 423. A first connecting rod 424 is provided on the fixed connecting block 423. The first connecting rod 424 is movably connected to a speed regulating component 44 and a pushing component 43.

[0066] Further, see Figures 1-9 The actuating component 43 includes:

[0067] The second connecting rod 431 is movably connected at one end to the first connecting rod 424, and the second connecting rod 431 is movably connected to the speed regulating component 44;

[0068] A fixed rotating pin 432 is used, and the second connecting rod 431 is connected to a fixed sleeve 433 via the fixed rotating pin 432. The fixed sleeve 433 is provided in the fixed sleeve.

[0069] Further, see Figures 1-9The speed regulating component 44 includes:

[0070] A first guide groove 441, one end of which is fixedly connected to the fixing frame 2, and the first guide groove 441 adopts an arc-shaped structure;

[0071] A sliding arc-shaped block 442 is disposed in the first guide groove 441, and the first guide groove 441 is movably connected to the sliding arc-shaped block 442.

[0072] The third connecting rod 443 has one end movably connected to the sliding arc block 442, and the other end movably connected to the second connecting rod 431 and the first connecting rod 424.

[0073] In this embodiment, the power rotating plate 421 is a power component. When the power rotating plate 421 is activated, it drives the connecting rod 422 to rotate. The connecting rod 422 drives the fixed connecting block 423 to rotate. The fixed connecting block 423 drives the first connecting rod 424 to rotate. At the same time, the first connecting rod 424 is symmetrically arranged about the fixed connecting block 423, so that the second connecting rod 431 and the third connecting rod 443 can be located between the two first connecting rods 424.

[0074] Subsequently, the first connecting rod 424 pushes the second connecting rod 431, and the second connecting rod 431 pushes the fixed sleeve 433 through the fixed rotating pin 432. Due to the limiting effect of the fixed frame 2, the movement trajectory of the fixed sleeve 433 is linear. At the same time, the fixed sleeve 433 can drive the push plate 45 to move upward. When the push plate 45 moves upward, the pressure in the water tank 3 increases, ensuring that the water output of the water outlet pipe 7 can meet the dust removal requirements.

[0075] When the water output from the outlet pipe 7 is insufficient, the position of the sliding arc block 442 can be adjusted to change the position of the sliding arc block 442 within the first guide groove 441, thereby changing the angle of the third connecting rod 443. This can change the movement trajectory of the second connecting rod 431, thus achieving the effect of changing the movement speed of the fixed sleeve 433.

[0076] The working principle of this invention is:

[0077] The second rotating rod 632 is movably connected to the mounting block 61, so that the second rotating rod 632 rotates. At the same time, when the second rotating rod 632 rotates, it drives the sweeping rod 633 to rotate. When the sweeping rod 633 rotates, the other end of the sweeping rod 633 passes through the water outlet of the water outlet pipe 7 in an alternating manner.

[0078] The sweeping rod 633 swings up and down, passing through the water outlet of the water pipe 7 during the swing, so that the sweeping rod 633 can disperse the water sprayed from the water pipe 7, increase the water spray coverage of the water pipe 7, and ensure the increase of the dust removal range. At the same time, the two sets of sweeping rods 633 can ensure the stable improvement of the water outlet surface of the water pipe 7.

[0079] When the water output from the outlet pipe 7 is insufficient, the position of the sliding arc block 442 can be adjusted to change the position of the sliding arc block 442 within the first guide groove 441, thereby changing the angle of the third connecting rod 443. This can change the movement trajectory of the second connecting rod 431, thus achieving the effect of changing the movement speed of the fixed sleeve 433.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
