Technical Field
[0001] This invention relates to the field of coal transportation equipment technology, specifically to an automatic spray dust suppression device for a mining belt conveyor. Background Technology
[0002] Mining belt conveyors are specialized transportation equipment used in the mining industry. They are mainly used for the continuous or intermittent transportation of materials such as coal and ore. Mining belt conveyors are driven by electric motors to rotate drums, which in turn drive the conveyor belt made of annular rubber or synthetic materials. The materials are placed on the conveyor belt and move continuously and stably through the drum and idler assembly, achieving long-distance transportation. A large amount of dust is generated during the coal transportation process.
[0003] Coal mine dust is a major hidden danger to coal mine safety, posing a long-term threat to mine safety and the health of coal miners. With increasing national emphasis on coal mine safety, efforts to control coal mine dust have been intensifying year by year. Various research and application departments have developed numerous equipment and methods to control coal dust, achieving good results, but many shortcomings still exist. Existing dust suppression devices remain operational throughout the operation of belt conveyors, even when the conveyors are unloaded, leading to water waste. Coal is easily unevenly distributed when dumped onto the conveyor, resulting in varying amounts of dust and requiring different amounts of water for dust suppression spray. Furthermore, the spray from the dust suppression device combines with dust, causing the dust to fall and generate wastewater. This wastewater accumulates on the top of the conveyor belt and then overflows onto the working ground, making it muddy. This not only affects the workers' working environment but also wastes water resources. Therefore, we propose an automatic spray dust suppression device for mining belt conveyors to solve these problems. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention employs a combination of a belt conveyor and a flow regulation mechanism.

[0016] This invention employs a combination of a flow regulation mechanism and a dust suppression mechanism. By adjusting the rotation angle of the regulating plate through the descent depth of the detection rod, the amount of water transported in each water distribution pipe varies, resulting in different atomization amounts produced by the atomizing nozzles. This overcomes the shortcomings of existing technologies and achieves the technical effect of zoned dust suppression for coal on belt conveyors.
[0017] This invention employs a combination of a pressure bar and a recovery mechanism. By pressing down the pressure bar, the guide pipe descends, creating a groove on the side of the belt conveyor. This allows the carbon and water mixture generated by the spray to enter the recovery box for solid-liquid separation. The recovered water then enters the lower layer of coal cargo through a pipe. This overcomes the shortcomings of existing technologies and achieves internal wetting of the coal layer. As a result, even if the belt conveyor vibrates or bumps during transport, the amount of dust generated by the lower layer of coal is greatly reduced, resulting in better dust suppression and higher dust suppression efficiency.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example
[0023] Please see Figure 1-2The present invention provides a technical solution: an automatic spray dust suppression device for a mining belt conveyor, including a belt conveyor 1 and multiple sets of water storage tanks 2 installed on the side wall of the frame of the belt conveyor 1. Each set of water storage tanks 2 is provided with a flow regulation mechanism 3 at the bottom, a dust suppression mechanism 4 at the top of the water storage tanks 2, and a recycling mechanism 6 on the side wall of each set of water storage tanks 2. It should be noted that the flow regulating mechanism 3 includes a protective shell 31, a support rod 35, a rotating plate 311, and a rotating shaft 312. The top of the protective shell 31 is fixedly connected to the bottom of the water storage tank 2, and the side wall of the protective shell 31 is fixedly connected to an regulating box 32. The regulating box 32 is located directly below the belt conveyor 1. Multiple sets of regulating rods 33 are movably inserted into the top wall of the regulating box 32. Each regulating rod 33 is fixedly connected to the top of a detection rod 34, and the top of the detection rod 34 abuts against the bottom wall of the belt conveyor 1. It should be noted that a pressure rod 5 is fixedly connected to the side wall of the detection rod 34, and the side wall of the pressure rod 5 is connected to the recycling mechanism 6. Example
[0024] Please see Figure 3-9 This is the second embodiment of the present invention, which is based on the previous embodiment; Specifically, the bottom of the adjusting rod 33 is fixedly connected to the top of the support rod 35, and the bottom of the support rod 35 is fixedly connected to the support spring 36. The bottom of the support spring 36 is fixedly connected to the bottom surface of the adjusting box 32. The side wall of the support rod 35 is fixedly connected to the ring 38, and the middle of the ring 38 is rotatably connected to the support shaft 37. Both sides of the support shaft 37 are fixedly connected to the inner wall of the protective shell 31. The support spring 36 is compressed after being pressured by the detection rod 34. After the detection rod 34 is depressurized, it pushes the detection rod 34 to quickly reset, which can conveniently and quickly monitor the no-load status of the belt conveyor 1.
[0025] It should be noted that a support frame 39 is fixedly connected to the side wall of the ring 38, and a rotating rod 310 is movably hinged to the inner side wall of the support frame 39. The top of the rotating rod 310 is movably connected to the bottom of the rotating plate 311, the top of the rotating plate 311 is fixedly connected to the bottom of the rotating shaft 312, the top of the rotating shaft 312 movably extends upward through the bottom wall of the water storage tank 2, and the top of the rotating shaft 312 is movably connected to the inner top wall of the water storage tank 2 through a bearing.
[0026] It should be noted that an adjusting plate 313 is fixedly inserted into the rotating shaft 312. The top wall of the adjusting plate 313 has an adjusting groove 314. The side wall of the adjusting plate 313 is movably engaged in the slide rail 315. The top of the slide rail 315 is fixedly connected to the top wall of the water storage tank 2. A sealing plate 316 is fixedly inserted into the bottom of the water storage tank 2. The top of the adjusting plate 313 movably abuts against the bottom of the sealing plate 316. A water outlet groove 317 is opened on the sealing plate 316. The rotating rod 310 drives the rotating plate 311 to rotate, and the rotating plate 311 drives the rotating shaft 312 to rotate, thereby causing the adjusting plate 313 to rotate. During the rotation of the adjusting plate 313, the adjusting groove 314 gradually overlaps with the water outlet groove 317 opened on the sealing plate 316. The more the adjusting groove 314 overlaps with the water outlet groove 317, the more water will be discharged, thus enabling the spraying of unevenly distributed coal on the belt conveyor 1 in different sections.
[0027] In addition, the dust suppression mechanism 4 includes a dustproof shell 41. The top of the water tank 2 is fixedly connected to the dustproof shell 41. The top of the dustproof shell 41 is fixedly connected to a vertical box 42. The top of the vertical box 42 is fixedly connected to a support cylinder 43. Multiple water pipes 46 are fixedly connected to the inner wall of the support cylinder 43. Multiple atomizing nozzles 47 are fixedly installed at the bottom of each water pipe 46. The bottom of the atomizing nozzles 47 moves through the bottom wall of the support cylinder 43 and is exposed. Each atomizing nozzle 47 is set directly above the belt conveyor 1. By spraying downwards through the atomizing nozzles 47, dust is quickly suppressed on the goods on the belt conveyor 1.
[0028] Specifically, a sealing cover 44 is fixedly connected to the top of the water storage tank 2, and the number of sealing covers 44 is the same as the number of sealing plates 316. The top of the sealing cover 44 covers the top of the sealing plate 316, and a water supply pipe 45 is fixedly connected to the top of the sealing cover 44. The top of the water supply pipe 45 is fixedly connected to the water distribution pipe 46. By setting multiple water distribution pipes 46, in conjunction with the flow regulation mechanism 3, the goods on the belt conveyor 1 are sprayed in sections, thereby achieving the technical effect of section dust reduction.
[0029] It should be noted that the recycling mechanism 6 includes a recycling box 61 and an insertion tube 612. The recycling box 61 is fixedly connected to the side wall of the water storage tank 2. A rectangular groove 62 is opened on the outer wall of the recycling box 61. A filter box 8 is movably placed in the rectangular groove 62. Multiple sets of filter holes 801 are opened on the bottom wall of the filter box 8. A baffle 63 is fixedly connected to the inner wall of the recycling box 61. The baffle 63 is set with a U-shaped structure. The bottom of the filter box 8 is movably placed on the baffle 63. The filter box 8 facilitates the rapid filtration of carbon and water mixtures. The filter box 8 is also easy to remove for collection and cleaning, making it more practical and flexible.
[0030] It should be noted that a guide pipe 64 is movably inserted into the top of the recycling bin 61. The guide pipe 64 has an inverted L-shaped cross-section, and its bottom is movably abutted against the top belt of the belt conveyor 1. An arc-shaped limiting plate 65 is fixedly connected to the bottom of the guide pipe 64. A limiting rod 66 is fixedly connected to the bottom of the limiting plate 65. A limiting ring 67 is movably sleeved on the limiting rod 66. The side wall of the limiting ring 67 is fixedly connected to the inner wall of the recycling bin 61. A traction rope 68 is fixedly connected to the bottom of the limiting rod 66. The bottom of the traction rope 68 passes through the recycling bin 61 and extends downward. The bottom of the traction rope 68 is fixedly connected to the top of the pressure rod 5. The pressure rod 5 drives the traction rope 68 to move downward, and the traction rope 68 drives the limiting rod 66 to move downward. By setting the limiting ring 67, the movement of the limiting rod 66 is more stable. The limiting rod 66 drives the guide pipe 64 to move downward through the limiting plate 65, pressing down on the top belt of the belt conveyor 1 to create a guide channel.
[0031] In addition, a return spring 614 is movably sleeved on the limiting rod 66. The top end of the return spring 614 is fixedly connected to the bottom wall of the limiting ring 67, and the bottom end of the return spring 614 is fixedly connected to the top of the baffle 63. A water pump 69 is fixedly installed on the inner wall of the recycling box 61. A control key is provided on the outer wall of the recycling box 61 and electrically connected to the water pump 69. A suction pipe 610 is installed at the bottom of the water pump 69, and the bottom end of the suction pipe 610 abuts against the inner bottom surface of the recycling box 61. A circulation pipe 611 is installed at the top of the water pump 69. The circulation pipe 611 extends outward through the side wall of the recycling box 61. The top of the circulation pipe 611 is fixedly connected to the insertion pipe 612. The water is pumped into the insertion pipe 612 by the water pump 69. The insertion pipe 612 has a through hole 613 to facilitate the outflow of filtered water. When the belt conveyor 1 is loaded, the bottom end of the insertion pipe 612 is inserted into the coal. The filtered water enters the lower layer of coal through the through hole 613 to moisten the inside. This greatly reduces the amount of dust generated by the lower layer of coal during the transportation process, even if the belt conveyor 1 vibrates or bumps.
[0032] Specifically, the cross-section of the insertion tube 612 is an inverted U-shaped structure, and multiple sets of through holes 613 are symmetrically opened on the inner wall of the insertion tube 612. The top of the insertion tube 612 is fixedly connected to the inner top surface of the support shell 7 through the mounting bracket, and the side wall of the support shell 7 is fixedly connected to the support cylinder 43.
[0033] Please see Figures 1 to 9 ; In use, the water storage tank 2 is first installed on the side wall of the belt conveyor 1 frame. The water storage tank 2 is then connected to the water inlet pipe and the air inlet pipe. A flow regulation mechanism 3 is installed to perform no-load detection on the belt conveyor 1, thereby adjusting the liquid flow rate of the dust suppression mechanism 4. When the belt conveyor 1 is loaded with coal, the belt at the top of the belt conveyor 1 will sink, pressing down on the detection rod 34. The downward movement of the detection rod 34 pushes the adjustment rod 33, causing one side of the support rod 35 to move downward, driving the ring 38 to rotate. The rotation of the ring 38 drives the support frame 39 to move upward, which in turn drives the rotating plate 311 to rotate via the rotating rod 310. The rotating plate 311 then drives the rotating shaft 312 to rotate. The belt conveyor rotates, causing the adjusting plate 313 to rotate. During the rotation, the adjusting groove 314 gradually overlaps with the water outlet groove 317 on the sealing plate 316. The heavier the coal on the belt conveyor 1, the deeper the detection rod 34 descends, the greater the rotation angle of the adjusting plate 313, and the more the adjusting groove 314 overlaps with the water outlet groove 317, resulting in a greater water output. This allows for zoned spraying of unevenly distributed coal on the belt conveyor 1, saving water and improving dust suppression. The detection rod 34 can also flexibly detect whether the belt conveyor 1 is unloaded, eliminating the need for manual control, making it more flexible and intelligent, saving labor costs, and improving economic efficiency.
[0034] During use, the flow regulation mechanism 3 works in conjunction with the dust suppression mechanism 4. When the detection rod 34 detects that the belt conveyor 1 is loaded, it moves downward. The dust suppression water enters different water supply pipes 45 through multiple sets of sealing covers 44. The water supply pipes 45 deliver the water to the water distribution pipes 46, and then spray it downward through the atomizing nozzles 47 to quickly suppress dust on the goods on the belt conveyor 1. By setting multiple sets of water supply pipes 46, in conjunction with the flow regulation mechanism 3, the goods on the belt conveyor 1 are sprayed in sections, effectively preventing belt slippage and water waste.
[0035] During operation, when the belt conveyor 1 is loaded, the detection rod 34 descends, causing the pressure rod 5 to move downwards. The pressure rod 5 then moves the traction rope 68 downwards, which in turn moves the limiting rod 66 downwards. A limiting ring 67 ensures more stable movement of the limiting rod 66. The limiting rod 66, via the limiting plate 65, moves the guide pipe 64 downwards, pressing down on the top belt of the belt conveyor 1 to create a guide channel. This allows excess water from the spray to enter the recovery box 61 through the guide pipe 64 and be absorbed into the rectangular channel. The filter box 8 inside 62 quickly filters the carbon and water mixture. The filtered water is pumped by water pump 69 to the insertion tube 612. The insertion tube 612 has a through hole 613 to facilitate the outflow of filtered water. When the belt conveyor 1 is loaded, the bottom end of the insertion tube 612 is inserted into the coal. The filtered water enters the lower layer of coal through the through hole 613 to moisten the inside. This greatly reduces the amount of dust generated by the lower layer of coal during the transportation process, even if the belt conveyor 1 vibrates or bumps. The dust reduction effect is better and the dust reduction efficiency is higher.
