Description

Technical Field

[0001] This invention relates to the field of tunnel dust removal technology, specifically to a dust removal device and method for underground tunnels in metal mines. Background Technology

[0002] Metal mine underground tunnels refer to underground passages excavated during the underground mining of metal ores for purposes such as reaching the ore body, mining and transporting ore, ventilation, and ensuring personnel safety. These tunnels are important infrastructure for mine production and are of great significance for achieving efficient and safe mineral resource development. In order to protect the health of mining personnel, dust removal is usually required in the tunnels during mining operations.

[0003] CN118526893A discloses a dust removal and filtration device for tunnel excavation, comprising a base; a fan is fixedly connected to the top of the outer wall of the base via a first column; an air duct is provided at the output end of the fan; the outer wall of the air duct is fixedly connected to the top of the outer wall of the base via a second column; a filter plate is fixedly connected to the inner wall of the air duct; the above application uses a fan to draw air through the air duct, causing dust to be absorbed from one end of the air duct. When the dust is drawn into the air duct, it encounters the filter plate under the action of suction, causing the filter plate to block larger dust particles, while smaller dust particles pass through the filter plate and exit from one end of the fan through the air duct. The structure of the first channel, connecting pipe, and storage shell allows the larger dust particles to be collected.

[0004] Although the aforementioned applications and prior art can filter and collect dust using wind power, eliminating the need for water mist spraying and thus making them safer and reducing the probability of accidents, when these applications and prior art are used for dust removal in underground roadways of metal mines, the presence of metal particles in these roadways can cause filter plate blockage after prolonged use, leading to reduced dust removal efficiency. Furthermore, when water-soaked materials absorb dust, the dust accumulates on the surface of the materials, making subsequent use inconvenient. Additionally, when using water-soaked materials to absorb dust, excessive dust can cause some dust to accumulate inside the air duct, further affecting the dust removal effect. Therefore, we propose a dust removal device and method for underground roadways in metal mines. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a dust removal device and method for underground roadways in metal mines. It offers advantages such as ease of dust removal, easy cleaning, and effective handling of excess dust. This solves the problems encountered by the aforementioned applications and existing technologies in dust removal in underground metal mine roadways. Due to the presence of metal particles in the roadways, prolonged use of these technologies can cause filter plate blockage, leading to reduced dust removal efficiency. Furthermore, when water-soaked materials absorb dust, the dust accumulates on the surface of the materials, hindering subsequent use. Additionally, when using water-soaked materials to absorb dust, excessive dust accumulation can cause some dust to accumulate inside the duct, further affecting the dust removal effect.

[0007] (II) Technical Solution

[0008] To achieve the aforementioned objectives of facilitating dust removal, cleaning, and excess disposal, this invention provides the following technical solution: a dust removal device for underground roadways in metal mines, comprising: a drive box and a dust collection box disposed on top of the drive box.

[0027] Step 4: When the collection component is operating, it synchronously drives the processing component, so that the processing component can process the dust that has not been adsorbed in the dust collection box.

[0028] (III) Beneficial Effects

[0029] Compared with the prior art, the present invention provides a dust removal device and method for underground roadways in metal mines, which has the following beneficial effects:

[0030] 1. The dust removal device and method for underground roadways in metal mines utilizes dust removal components. By activating the drive cylinder via the control panel, the drive cylinder moves the cross pusher through the telescopic rod, causing the cross pusher to squeeze water from the water tank into the dust removal box via the extrusion block. This water flow spreads across the surface of the dust removal rods. Then, the drive cylinder is returned to its original position via the control panel, and the exhaust fan is activated. The exhaust fan draws external dust into the dust removal box, causing the dust to adhere to the surface of the dust removal rods, thus achieving the desired dust removal effect.

[0031] 2. The dust removal device and method for underground roadways in metal mines utilizes a combination of a cleaning rod assembly and a collection assembly. When dust needs to be cleaned from the surface of the dust removal rods, the squeezing block forces water from the water tank into the dust removal box. The water flow gradually rises within the dust removal box, causing the floating plate to rise. During the rise of the floating plate, the scraping holes scrape away the dust from the surface of the dust removal rods. When the top of the floating plate coincides with the top of the dust removal rod, the drive motor is activated via the control panel. The drive motor drives the screw block to move via the drive screw, causing the screw block to move the U-shaped scraper. As the U-shaped scraper moves, it pushes the dust on the top of the floating plate. When one end of the U-shaped scraper moves to the second ash inlet trough, the dust falls through the second ash inlet trough into the inside of the collection box, thus cleaning the dust from the surface of the dust removal rods and achieving an easy cleaning effect.

[0032] 3. The dust removal device and method for underground roadways in metal mines utilizes a combination of collection and processing components. When the drive motor moves the screw block via the drive screw, the drive screw simultaneously drives several fan blades and scrapers to rotate. The suction generated by the rotating fan blades draws the dust that has not been adsorbed in the dust collection box to one end of the filter plate. During the rotation of the scrapers, the dust attached to one end of the filter plate is scraped off. The falling dust falls into the inside of the collection box through the first ash inlet trough, thereby treating the dust that has not been adsorbed in the dust collection box, thus achieving the effect of over-treatment.

[0033] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0046] 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.

[0047] The devices or elements referred to in the embodiments of this application or implied herein must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0048] For a specific implementation example, please refer to Implementation Example 1. Figures 1 to 11 A dust removal device for underground roadways in a metal mine includes: a drive box 1 and a dust collection box 13 disposed on top of the drive box 1.

[0049] Water tank 11 is fixedly connected to one side of drive box 1. The top of water tank 11 is fixedly connected to the bottom of dust collection box 13. Several first water inlet grooves 111 are opened on the top of water tank 11. Several second water inlet grooves 131 are opened at the bottom of the interior of dust collection box 13. Several first water inlet grooves 111 and several second water inlet grooves 131 are connected to each other.

[0050] The collection box 12 is fixedly connected to the top of the drive box 1. One side of the collection box 12 is fixedly connected to one side of the dust collection box 13. The surface of the dust collection box 13 is provided with a control panel 132.

[0051] Dust removal component 2 is installed inside dust removal box 13 and is used to collect dust inside the tunnel. Dust removal component 2 includes several dust removal rods 23 fixedly connected inside dust removal box 13 and a blower 24 fixedly connected to one side of dust removal box 13. Dust removal component 2 also includes a drive cylinder 21 fixedly connected inside drive box 1 and a squeezing block 22 slidably connected inside water tank 11. The output end of drive cylinder 21 is differentially connected to telescopic rod 211. The end of telescopic rod 211 away from drive cylinder 21 is fixedly connected to cross pusher 212. The end of cross pusher 212 away from telescopic rod 211 is fixedly connected to one end of squeezing block 22.

[0052] The cleaning rod assembly 3 is located inside the dust collection box 13 and is used to clean the surface of the dust collection assembly 2;

[0053] The collecting component 4 is located inside the dust collection box 13 to prevent dust from accumulating inside the dust collection box 13;

[0054] Processing component 5 is located inside the collection box 12 and is used to process the remaining dust inside the dust collection box 13.

[0055] It should be noted that the bottom of the drive box 1 and the water tank 11 are equipped with liftable casters. By setting the liftable casters, this application can be easily moved to a designated position in the tunnel. The liftable casters can cope with the uneven road surface inside the tunnel, thereby ensuring that when the water in the water tank 11 enters the dust removal box 13, the water flow can rise smoothly. One end of the water tank 11 is equipped with a water inlet, through which water can be delivered into the water tank 11. When the water in the water tank is squeezed into the dust removal box 13, the water flow can overflow the top of the dust removal rod 23. The inside of the collection box 121 contains a small amount of water. The operating chamber 123 and the exhaust fan 24 are at the same level. The squeezing block 22 is in close contact with the water tank 11.

[0056] When dust needs to be collected inside the tunnel, the drive cylinder 21 is activated via the control panel 132. The drive cylinder 21 moves the cross pusher 212 via the telescopic rod 211, causing the cross pusher 212 to squeeze water from the water tank 11 into the dust collection box 13 via the squeezing block 22. The water flow spreads across the surface of the dust removal rod 23. Then, the drive cylinder 21 is returned to its original position via the control panel 132 and the exhaust fan 24 is activated. The exhaust fan 24 draws the dust from the outside into the dust collection box 13, causing the dust to adhere to the surface of the dust removal rod 23, thereby removing the dust from the outside.

[0057] For a specific embodiment two, please refer to Figures 1 to 8 Based on the dust removal device for underground roadways in metal mines provided in Specific Embodiment 1, this embodiment provides a further technical solution:

[0058] The cleaning rod assembly 3 includes a floating plate 31 that is slidably connected inside the dust collection box 13. The top of the floating plate 31 is provided with a plurality of scraping holes 311, and the plurality of scraping holes 311 are slidably connected to the surface of a plurality of dust collection rods 23.

[0059] It should be noted that the material of the float plate 31 can be wood or plastic, and there is no limitation here. The rise and fall of the water surface can drive the float plate 31 to rise and fall. The diameter of the scraping hole 311 is matched with the diameter of the dust removal rod 23.

[0060] When it is necessary to treat the dust on the surface of the dust removal rod 23, the drive cylinder 21 is restarted through the control panel 132. The drive cylinder 21 drives the cross pusher 212 to move through the telescopic rod 211, so that the cross pusher 212 squeezes the water in the water tank 11 into the dust removal box 13 through the squeezing block 22. When the squeezing block 22 squeezes the water in the water tank 11 into the dust removal box 13, the water flow gradually rises in the dust removal box 13, thereby driving the floating plate 31 to rise. During the process of the floating plate 31 rising, the scraping hole 311 scrapes the dust on the surface of the dust removal rod 23, so that the dust on the surface of the dust removal rod 23 is transferred to the top of the floating plate 31.

[0061] For a specific embodiment three, please refer to Figures 1 to 8 Based on the dust removal device for underground roadways in a metal mine provided in Specific Embodiment Two, this embodiment provides a further technical solution:

[0062] A collection box 121 is slidably connected inside the collection box 12. A handle 122 is fixedly connected to the surface of the collection box 121. An operating chamber 123 is opened inside the collection box 12. Several air inlets 124 are opened at one end of the operating chamber 123. A first ash inlet trough 125 is opened at the bottom of the operating chamber 123. A second ash inlet trough 126 is opened at one end of the operating chamber 123. The collection assembly 4 includes a drive motor 41 fixedly connected inside the operating chamber 123. A drive screw 411 is fixedly connected to the output end. A screw block 42 is threadedly connected to the surface of the drive screw 411. A U-shaped scraper 421 is fixedly connected to one end of the screw block 42. A T-shaped slider 422 is fixedly connected to both the surface and back of the U-shaped scraper 421. A T-shaped groove 133 is provided on the inner wall of the dust collection box 13. The T-shaped slider 422 is slidably connected inside the T-shaped groove 133. A moving groove 134 is provided at one end of the dust collection box 13 for the U-shaped scraper 421 and the screw block 42 to move.

[0063] It should be noted that when the top of the floating plate 31 coincides with the top of the dust removal rod 23, the bottom of the U-shaped scraper 421 is in contact with the top of the floating plate 31.

[0064] When it is necessary to collect the dust on the top of the floating plate 31, when the top of the floating plate 31 coincides with the top of the dust removal rod 23, the drive motor 41 is started through the control panel 132. The drive motor 41 drives the screw block 42 to move through the drive screw 411, which in turn drives the U-shaped scraper 421 to move. When the U-shaped scraper 421 moves, it pushes the dust on the top of the floating plate 31. When one end of the U-shaped scraper 421 moves to the second dust inlet trough 126, the dust falls into the collection box 121 through the second dust inlet trough 126, thereby treating the dust.

[0065] For a specific implementation example, please refer to Implementation Example 4. Figures 1 to 6 Based on the dust removal device for underground roadways in a metal mine provided in Specific Embodiment 3, this embodiment provides a further technical solution:

[0066] The processing component 5 includes a filter plate 51 fixedly connected inside the operating cavity 123. The surface of the filter plate 51 is provided with a plurality of filter holes 511. The processing component 5 also includes a plurality of fan blades 52 and a plurality of scrapers 53 fixedly connected to the surface of the drive screw 411. The plurality of fan blades 52 are located between the drive motor 41 and the filter plate 51, and the plurality of scrapers 53 are in contact with one end of the filter plate 51.

[0067] It should be noted that the control panel 132 is electrically connected to the exhaust fan 24, the drive cylinder 21, and the drive motor 41. The operation buttons on the surface of the control panel 132 are used to control the opening and closing of the exhaust fan 24, the drive cylinder 21, and the drive motor 41. When the drive motor 41 reverses, the drive screw 411 drives the screw block 42, several fan blades 52, and several scrapers 53 to rotate, so that the screw block 42 drives the U-shaped scraper 421 to return to the initial state. When the several fan blades 52 reverse, they can blow away the dust adsorbed inside the filter hole 511, so that the dust is no longer stuck inside the filter hole 511, thereby extending the service life of the filter plate 51.

[0068] When the remaining dust inside the dust collector 13 needs to be processed, when the drive motor 41 drives the screw block 42 to move through the drive screw 411, the drive screw 411 synchronously drives several fan blades 52 and scraper 53 to rotate. The suction force generated by the rotation of several fan blades 52 attracts the dust that has not been adsorbed in the dust collector 13 to one end of the filter plate 51. During the rotation of several scraper 53, the dust attached to one end of the filter plate 51 is scraped off. The fallen dust falls into the inside of the collection box 121 through the first dust inlet trough 125, thereby processing the dust that has not been adsorbed in the dust collector 13.

[0069] In a specific embodiment five, the present invention also provides a method for dust removal in underground roadways of metal mines, which specifically includes the following steps:

[0070] Step 1: When it is necessary to remove dust from the tunnel, the dust removal rod 23 is covered with water stains through the dust removal component 2, and then the dust from the outside is drawn into the dust removal box 13 by the exhaust fan 24, so that the dust removal rod 23 can absorb the dust.

[0071] Step 2: When it is necessary to clean the dust on the surface of the dust removal rod 23, restart the dust removal component 2 to drive the cleaning rod component 3 to operate, thereby allowing the cleaning rod component 3 to clean the dust on the surface of the dust removal rod 23.

[0072] Step 3: When dust needs to be collected, start the collection component 4 so that the collection component 4 collects the dust on the top of the cleaning rod component 3;

[0073] Step 4: When the collecting component 4 is operating, the collecting component 4 synchronously drives the processing component 5, so that the processing component 5 processes the dust that has not been adsorbed in the dust collection box 13.

[0074] Working principle: In use, move the device to the designated location in the tunnel, aiming the exhaust fan 24 at the dust area. When dust collection is needed inside the tunnel, start the drive cylinder 21 via the control panel 132. The drive cylinder 21 moves the cross pusher 212 via the telescopic rod 211, causing the cross pusher 212 to squeeze water from the water tank 11 into the dust collection box 13 through the squeezing block 22. This causes the water flow to spread across the surface of the dust collection rod 23. Then, return the drive cylinder 21 to its original position via the control panel 132 and start the exhaust fan 24. The exhaust fan 24 draws the external dust into the dust collection box 13, causing the dust to adhere. Dust is removed from the surface of the dust removal rod 23. When dust removal is needed on the surface of the dust removal rod 23, the drive cylinder 21 is restarted via the control panel 132. The drive cylinder 21 moves the cross pusher 212 via the telescopic rod 211, causing the cross pusher 212 to squeeze water from the water tank 11 into the dust removal box 13 via the squeezing block 22. As the squeezing block 22 squeezes the water from the water tank 11 into the dust removal box 13, the water flow gradually rises in the dust removal box 13, thereby causing the float plate 31 to rise. During the rise of the float plate 31, the scraping hole 311 scrapes away the dust on the surface of the dust removal rod 23. This causes the dust on the surface of the dust collector rod 23 to be transferred to the top of the floating plate 31. When it is necessary to collect the dust on the top of the floating plate 31, when the top of the floating plate 31 coincides with the top of the dust collector rod 23, the drive motor 41 is started through the control panel 132. The drive motor 41 drives the screw block 42 to move through the drive screw 411, which in turn drives the U-shaped scraper 421 to move. When the U-shaped scraper 421 moves, it pushes the dust on the top of the floating plate 31. When one end of the U-shaped scraper 421 moves to the second dust inlet trough 126, the dust falls into the collection box 121 through the second dust inlet trough 126. To process the dust, when the remaining dust inside the dust collector 13 needs to be treated, when the drive motor 41 drives the screw block 42 to move through the drive screw 411, the drive screw 411 simultaneously drives several fan blades 52 and scraper rods 53 to rotate. The suction force generated by the rotation of the fan blades 52 attracts the dust that has not been adsorbed in the dust collector 13 to one end of the filter plate 51. During the rotation of the scraper rods 53, the dust attached to one end of the filter plate 51 is scraped off. The fallen dust falls into the collection box 121 through the first dust inlet trough 125, thereby processing the dust that has not been adsorbed in the dust collector 13.
