[0002] Coal mines are areas where coal resources are extracted from coal-rich mining areas, and are mainly divided into underground coal mines and open-pit coal mines.
[0003] Coal mining is the core of coal production. It mainly involves developing coal ore bodies, extracting and transporting coal, and transforming coal from underground into surface resources. During the coal mining stage, a large amount of dust particles are generated in the air. Wet dust collectors are usually used to contact water mist with the dust-laden gas, causing the dust particles to be captured and settled by the water mist. Alternatively, baghouse dust collectors are used to filter the dust-laden gas through a conveyor belt, trapping the dust particles on the surface of the filter bags, thereby achieving the dust removal effect.
[0004] During the dust removal process in coal mining, large particles in the air will directly enter the dust collector. Over time, large particles can easily clog the filter elements of the dust collector, resulting in a reduction in the filter area and thus reducing the dust removal efficiency.
[0005] Therefore, this utility model provides a coal mine ventilation and dust removal device. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] like Figures 1 to 7As shown in the embodiment of this utility model, a coal mine ventilation and dust removal device includes a dust collection box 1; a spray assembly 4 is installed at the bottom of the dust collection box 1; a moving assembly 5 is installed at the bottom of the spray assembly 4; a fan 10 is installed on the side wall of the dust collection box 1; a wind hood 11 is fixedly connected to the side of the dust collection box 1 away from the fan 10; the wind hood 11 is flared; two first locking blocks 12 are fixedly connected to the middle of the dust collection box 1; the first locking blocks 12 are located inside the dust collection box 1; the two first locking blocks 12 are arranged opposite each other; two second locking blocks 15 are fixedly connected to the middle of the dust collection box 1; the two second locking blocks 15 are arranged opposite each other; and an opening is provided at the top of the dust collection box 1. A first slot 17 is provided; a filter plate 13 is installed in the middle of the first slot 17; the filter plate 13 is installed in the middle of two first slot blocks 12; a filter screen 14 is fixedly connected to the middle of the filter plate 13; a second slot 18 is provided on the top of the dust collection box 1; an adsorption plate 16 is installed in the middle of the second slot 18; the adsorption plate 16 is installed in the middle of two second slot blocks 15; during operation, firstly, the filter plate 13 is inserted into the position corresponding to the first slot 17, so that the filter screen 14 is completely inserted into the dust collection box 1, then the adsorption plate 16 is inserted into the position corresponding to the second slot 18, the dust collection box 1 is moved to the designated position by the moving component 5, and the fan 10 is powered on and turned on. Fan 10 rotates, exhausting air to the outside of dust collection box 1 during its rotation. On the other side, fan 10 draws in external dust through dust collection box 1, and the dust from the coal mine is guided into the dust collection box 1 through hood 11. After entering the dust collection box 1, the dust first passes through the middle of filter screen 14, where large particles are intercepted and filtered. The filtered dust-laden airflow then passes through adsorption plate 16 and is discharged by fan 10. When passing through the middle of adsorption plate 16, the tiny particles inside the dust-laden gas are adsorbed by the adsorption plate 16, which adsorbs and traps harmful substances and gases on its surface, purifying the dust-laden gas before it is discharged. This process is part of the dust removal process. The spray component 4 sprays water into the surrounding air, causing the water molecules to settle upon contact with the dust, thus removing it. This structure effectively removes dust and impurities from the coal mine. The filter screen 14 provides initial filtration, effectively blocking and capturing larger dust particles, reducing the wear and clogging caused by the long-term accumulation of large particles. This also reduces the reduction in dust removal efficiency caused by clogging of the filter area. Simultaneously, the adsorption plate 16 removes fine dust particles and harmful gases from the air. The airflow carrying dust is then purified and discharged, ventilating the inside of the coal mine and improving the air quality, providing a safe and healthy working environment.
[0027] like Figure 4As shown, the adsorption plate 16 has a placement groove 2 in the middle; a hinge shaft 21 is fixedly connected to one end of the placement groove 2; a mesh plate 22 is installed in the middle of the hinge shaft 21; a groove 23 is formed at the end of the placement groove 2 away from the hinge shaft 21; multiple springs 24 are fixedly connected to the middle of the groove 23; a clamping plate 25 is fixedly connected to the end of the spring 24; the clamping plate 25 is slidably connected to the middle of the groove 23; during operation, when activated carbon is placed in the placement groove 2 in the middle of the adsorption plate 16, the clamping plate 25 is first squeezed, causing the clamping plate 25 to slide into the spring 24, and at the same time, the spring 24, which is squeezed, contracts with the clamping plate 25, and then the mesh plate 22 is rotated through the middle of the hinge shaft 21. After opening and placing the activated carbon inside the placement tank 2, press the clamping plate 25 again to rotate the mesh plate 22 into the placement tank 2. When the mesh plate 22 closes, release the clamping plate 25 and let it slide out through the elastic tension of the spring 24. The mesh plate 22 is fixed by the clamping plate 25. Through the above steps, the activated carbon can be quickly placed and replaced. When the activated carbon reaches saturation or needs to be replaced, the mesh plate 22 can be quickly opened to remove the old activated carbon and install the new activated carbon, effectively shortening the maintenance time. The rapid replacement process can restore the normal working state more quickly, thereby reducing the downtime caused by replacing activated carbon and effectively improving production efficiency.
[0028] like Figures 1 to 5As shown, the dust collection box 1 has two sliding grooves 3 on its top; the two sliding grooves 3 are located on both sides of the first slot 17; a slider 31 is slidably connected to the middle of the sliding groove 3; a cleaning box 32 is fixedly connected to the top of the two sliders 31; the filter plate 13 passes through the middle of the cleaning box 32; two cleaning rollers 33 are rotatably connected to the middle of the cleaning box 32; the two cleaning rollers 33 are arranged opposite each other; the cleaning rollers 33 are located inside the cleaning box 32; two scrapers 34 are fixedly connected to the bottom of the cleaning box 32; the scrapers 34 are arc-shaped; the ends of the scrapers 34 are in contact with the middle of the corresponding cleaning rollers 33; during operation, large particles in the dust are intercepted by the middle of the filter screen 14, and the dust particles adhere to the surface of the filter screen 14 after interception. After long-term use, dust particles accumulate on the surface of the filter screen 14. When cleaning is required, the filter plate 13 is pulled upwards, and the two cleaning rollers... The cylinder 33 is attached to both sides of the filter plate 13. As the filter plate 13 moves, the two cleaning rollers 33 rotate along with the filter plate 13. The cleaning rollers 33 clean the surface of the filter plate 13. As the cleaning rollers 33 rotate, the end of the scraper 34 scrapes away the impurities cleaned in the middle of the cleaning roller 33. After being scraped away by the scraper 34, the impurities slide down from the middle to the bottom of the scraper 34, thereby cleaning and collecting the impurities on the middle surface of the filter screen 14. Through the above structure, the impurities attached to the filter screen 14 can be cleaned regularly, keeping the filter screen 14 unobstructed, reducing the decrease in dust removal efficiency due to clogging, and reducing the damage caused by the filter screen 14 not being cleaned for a long time. This effectively reduces the frequency of replacement due to damage to the filter screen 14, thereby extending the service life of the filter screen 14. The unobstructed filter screen 14 can effectively reduce the dust concentration in the air and provide fresh air inside the coal mine.
[0029] like Figure 1 and Figure 5As shown, the spray assembly 4 includes a water tank 41; the water tank 41 is located at the bottom of the dust collector 1; an inlet pipe 46 is fixedly connected to the side wall of the water tank 41; a suction pipe 42 is fixedly connected to the side of the water tank 41 away from the inlet pipe 46; a water pump 43 is fixedly connected to the end of the suction pipe 42; the water pump 43 is fixedly connected to the side wall of the dust collector 1; an outlet pipe 44 is fixedly connected to the middle of the water pump 43; one end of the outlet pipe 44 is located at the top of the dust collector 1; multiple drainage channels 47 are opened in the middle of the outlet pipe 44; multiple spray heads 45 are rotatably connected to the middle of the outlet pipe 44; the multiple spray heads 45 are located at the corresponding drainage channels 47; during operation, water is placed in the middle of the water tank 41 through the end of the drainage channel 47, and during dust removal, the water pump 43 is activated. After the power is turned on, the water inside the water tank 41 is pumped into the water pipe 42 by the water pump 43. The water flows through the water pump 43 into the middle of the outlet pipe 44. The spray angle is adjusted by rotating multiple spray heads 45. After the water flows into the outlet pipe 44, it is discharged through multiple drainage channels 47. The water mist formed by the spray heads 45 is discharged into the surrounding environment, thereby settling the dust. Through the above structure, the water mist is sprayed into the environment around the coal mine, effectively adsorbing dust particles in the air and reducing the dust concentration in the working area. By adjusting the angle of the spray heads 45, the water mist can cover a wider dust removal area, thereby effectively capturing and adsorbing dust particles in the air. Adjusting the spray angle can reduce the diffusion range of the water mist when large-area spraying is not required, thereby saving water resources and energy consumption.
[0030] like Figure 1 and Figure 6 As shown, the moving component 5 includes multiple support rods 51; the support rods 51 are located at the bottom of the water tank 41; an extension rod 52 is slidably connected between the middle of every two support rods 51; a fastening bolt 53 is installed in the middle of the support rod 51; two casters 54 are fixedly connected to the middle of the extension rod 52; the two casters 54 are arranged opposite each other; during operation, the position of the coal mine dust removal is adjusted by moving the multiple casters 54, and the multiple fastening bolts 53 are rotated to move the fastening bolts 53 from the outside of the support rods 51, moving the dust removal box 1 upward, so that the extension rod 52 slides out inside the two support rods 51, and after the dust removal box 1 is adjusted to the specified height, the multiple fastening bolts 53 are tightened again to fix the extension rod 52, thereby adjusting the height of the dust removal box 1. Adjusting the overall dust removal height through the above structure can optimize the airflow path, and a suitable height can effectively reduce the interference of ground debris and water on the airflow. This makes the airflow more concentrated and stable, which helps to better capture and settle dust. A suitable dust removal height can effectively reduce collisions during movement, reduce the workload of the equipment due to excessively low ground clearance, and reduce the aggravation of equipment wear.
[0031] like Figure 7As shown, multiple fixed rods 6 are fixedly connected to the side wall of the hood 11; the multiple fixed rods 6 are equidistantly distributed in the middle of the hood 11; blades 61 are rotatably connected to the middle of the fixed rods 6; during operation, the multiple blades 61 are rotated, and at the same time the blades 61 rotate in the middle of the fixed rods 6. When the hood 11 draws in dust from the air around the coal mine, the direction of the airflow is adjusted. Through the above structure, the direction and volume of the airflow can be flexibly adjusted, and precise control can be made according to actual needs, so that the airflow can be accurately directed to the area that needs dust removal. By adjusting the opening and closing angle of the blades 61, the airflow is made more concentrated on the dust source, thereby effectively improving the dust removal efficiency.
[0032] like Figure 1 and Figure 5 As shown, two sound-absorbing cotton 7 are fixed to the side wall of the dust collection box 1; the two sound-absorbing cotton 7 are arranged opposite each other; during operation, when dust removal is carried out, the noise and vibration of the equipment during operation are absorbed by the sound-absorbing cotton 7 on both sides. The above structure can effectively absorb the noise generated during ventilation and dust removal, effectively reduce noise pollution, thereby improving the comfort of working, reducing the fatigue caused by being in a high-noise environment for a long time, and effectively improving work efficiency and safety.
[0033] During operation, firstly, insert the filter plate 13 into the first slot 17, ensuring the filter screen 14 is fully inside the dust collector 1. Then, insert the adsorption plate 16 into the second slot 18. Move the dust collector 1 to the designated position using the moving component 5. Power on the fan 10 and turn it on, causing it to rotate. During rotation, the fan 10 exhausts air to the outside of the dust collector 1. On the other side of the fan 10, external dust is drawn into the dust collector 1. The dust from the coal mine is then guided into the dust collector 1 through the hood 11. After entering the dust collector 1, the dust first passes through the middle of the filter screen 14, where large particles are intercepted and filtered. The filtered dust airflow passes through the adsorption plate 16 and is then discharged by the fan 10. During dust removal, the tiny particles inside the gas are adsorbed by the adsorption plate 16, which has adsorption properties. Harmful substances and gases are adsorbed and trapped on the surface, purifying the gas before it is discharged. During the dust removal process, the spray assembly 4 sprays water into the surrounding air. When water molecules come into contact with the dust, they settle, thus removing the dust. When activated carbon is placed in the placement groove 2 in the middle of the adsorption plate 16, the clamping plate 25 is first squeezed, causing it to slide into the spring 24. Simultaneously, the spring 24, under pressure, contracts along with the clamping plate 25. Then, the mesh plate 22 is rotated open via the hinge shaft 21. After the activated carbon is placed in the placement groove 2, the clamping plate 25 is squeezed again, rotating the mesh plate 22 into the placement groove 2. When the mesh plate 22 closes... When the clamping plate 25 is released, the elastic tension of the spring 24 causes the clamping plate 25 to slide out, fixing the mesh plate 22 in place. Large dust particles are intercepted in the middle of the filter screen 14. After interception, the dust particles adhere to the surface of the filter screen 14. After prolonged use, dust particles accumulate on the surface of the filter screen 14. When cleaning is required, the filter plate 13 is pulled upwards, and the two cleaning rollers 33 are attached to the sides of the filter plate 13. As the filter plate 13 moves, the two cleaning rollers 33 rotate with the filter plate 13, cleaning the surface of the filter plate 13. During the rotation of the cleaning rollers 33, the end of the scraper 34 scrapes away the impurities cleaned in the middle of the cleaning rollers 33. After being scraped away by the scraper 34, the impurities slide out from the middle. The dust falls to the bottom of the scraper 34, thus cleaning and collecting impurities on the surface of the middle part of the filter screen 14. Water is placed in the middle of the water tank 41 through the end of the drain trough 47. During dust removal, the water pump 43 is turned on, and the water inside the water tank 41 is pumped into the water pipe 42 through the water pump 43. The water flows through the water pump 43 into the middle of the outlet pipe 44. The spray angle is adjusted by rotating multiple spray heads 45. After the water flows into the outlet pipe 44, it is discharged through multiple drain troughs 47. The water mist formed by the spray heads 45 is discharged into the surrounding environment, thereby settling the dust. The position of the coal mine dust removal is moved and adjusted by multiple casters 54. Multiple fastening bolts 53 are rotated to move the fastening bolts 53 from the outside of the support rod 51, moving the dust collection box 1 upward.After the extension rod 52 slides out from inside the two support rods 51 and the dust collector box 1 is adjusted to the specified height, the multiple fastening bolts 53 are tightened again to fix the extension rod 52, thereby adjusting the height of the dust collector box 1. This causes the multiple blades 61 to rotate, and simultaneously, the blades 61 rotate in the middle of the fixed rod 6. When the hood 11 draws in dust from the air surrounding the coal mine, the direction of the airflow is adjusted. During the dust removal process, the noise and vibration generated during equipment operation are absorbed by the sound-absorbing cotton 7 on both sides.
