Description

Technical Field

[0001] This utility model relates to the field of dust control devices, specifically to a dust control device for explosive dust. Background Technology

[0002] In coal mining, blasting is typically used, generating a large amount of dust. To control this dust and prevent environmental impact, multiple mist cannons are usually placed near the blasting point for dust suppression. To ensure the mist spray has a better dust suppression effect, a dust suppressant is usually added to the water tank inside the mist cannon. However, in actual use, the dust suppressant is usually added directly to the water tank, resulting in a high concentration of it. Since the dust suppressant has strong viscosity, it requires prolonged stirring to fully mix with the water in the tank. This process is time-consuming and impractical, requiring improvement.

[0027] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0028] The following is in conjunction with the appendix Figures 1-6 This embodiment will be described in further detail.

[0029] Combination Figures 1-6 As shown, a dust control device for blasting dust in this embodiment includes a fog cannon body 10 and a water tank 100. The water tank 100 has a water storage cavity 300 with an opening at the top, and a tank cover 201 is provided at the opening of the water storage cavity 300. A dispersion component for dispersing dust suppressant is provided in the water storage cavity 300. The dispersion component includes a dispersion plate 306, and multiple slots 500 are provided on the dispersion plate 306 along its radial direction. A rotatable rotating shaft 309 is provided in the water storage cavity 300 along its height direction. The rotating shaft 309 passes through the dispersion plate 306. A scraper 400 for scraping the upper side of the dispersion plate 306 is provided on the outer wall of the rotating shaft 309. A striking element is provided on the lower side of the tank cover 201. The rotation of the scraper 400 drives the striking element to strike the dispersion plate 306. A stirring component is provided on the rotating shaft 309 located below the dispersion plate 306.

[0030] In actual use, the fog cannon body 10 of this embodiment has the existing structure. The water tank 100 is placed inside the fog cannon body 10 to supply water to the fog cannon body 10. When it is necessary to control the dust generated by the explosion, multiple fog cannon bodies 10 are placed around the explosion point. Water mist is sprayed by multiple fog cannon bodies 10, so that the dust control operation can be carried out better.

[0031] In actual use, a servo motor 102 is mounted on the upper side of the can lid 201 via a motor mounting bracket 200. The output end of the servo motor 102 is connected to the upper end of the rotating shaft 309 via a coupling. A water inlet pipe 103 is also provided on the upper side of the can lid 201. When it is necessary to prepare a mixed solution containing dust suppressant, an appropriate amount of water is first added to the water storage chamber 300 through the water inlet pipe 103. The servo motor 102 is then started, enabling it to drive the rotating shaft 309 to rotate, which in turn drives the scraper 400 to rotate. Then, the dust suppressant is added through the water inlet pipe. Pipe 103 is inserted into the water storage chamber 300, allowing the dust suppressant to remain on the dispersion plate 306. The dust suppressant on the dispersion plate 306 is scraped by the rotation of the scraper 400, so that the dust suppressant can enter the water storage chamber 300 located below the dispersion plate 306 in a more dispersed manner through multiple slots 500. This reduces the time required to stir the dust suppressant and water for practical use. At the same time, the rotation of the scraper 400 can drive the striking element to strike the dispersion plate 306, causing the dispersion plate 306 to vibrate, which can better prevent the dust suppressant from clogging the slots 500.

[0032] It should be noted that the dust suppressant used in this embodiment is a liquid dust suppressant, which has a certain viscosity when undiluted;

[0033] The fog cannon body 10 also includes a centrifugal pump 105. A connecting hose 101 communicating with the water storage chamber 300 is provided on the outer wall of the water tank 100. The end of the connecting hose 101 away from the water tank 100 is connected to the water inlet 104 of the centrifugal pump 105. Through the centrifugal pump 105, the prepared dust suppressant solution can be transported to the water inlet 104 of the centrifugal pump 105 through the connecting hose 101. A spray pipe is connected to the water outlet of the centrifugal pump 105. The end of the spray pipe away from the centrifugal pump 105 is connected to the atomizing nozzle 106 on the fog cannon body 10 to achieve water supply.

[0034] Specifically, the dispersion plate 306 is fixedly installed on the side wall of the water storage chamber 300, and the scraper 400 is fixedly connected to the outer side wall of the rotating shaft 309;

[0035] The mixing component is designed to drive the rotating shaft 309 to mix the dust suppressant and water. The rotation of the rotating shaft 309 can also drive the mixing component to move up and down, so that the mixing component can fully mix the water and dust suppressant in the water storage chamber 300 located below the dispersion plate 306. This allows the dust suppressant and water to be fully mixed, resulting in the water mist sprayed by the fog cannon body 10 having a better dust suppression effect.

[0036] The can lid 201 is fixedly installed at the opening of the water storage cavity 300 by screws; the motor mounting bracket 200 is fixedly installed on the upper side of the can lid 201 by screws; the lower end of the rotating shaft 309 is rotatably installed on the bottom wall of the water storage cavity 300 by bearings, and the upper end passes through the can lid 201 and is connected to the coupling, so that the rotating shaft 309 can be rotatably installed in the water storage cavity 300.

[0037] Combination Figures 3-4 As shown, in this embodiment, a first inclined surface is provided on one side wall of the scraper 400; the striking component includes a mounting cylinder 301 fixedly mounted on the lower side of the can lid 201, a fixing block 303 is provided inside the mounting cylinder 301 via a spring 302, a pushing rod 304 is provided on the lower side of the fixing block 303, a striking block 305 is provided at the lower end of the pushing rod 304, and a second inclined surface adapted to the first inclined surface is provided on the striking block 305.

[0038] In practical use, the mounting cylinder 301 has openings at both the top and bottom. The upper end of the spring 302 abuts against the lower side of the can lid 201, and the lower end abuts against the upper side wall of the fixing block 303, ensuring that the striking block 305 always abuts against the dispersing plate 306. The rotating shaft 309 drives the scraper 400 to rotate, causing the scraper 400 to drive the first inclined surface to rotate, allowing the first inclined surface to come into contact with the second inclined surface. The rotating shaft 309 continues to drive the scraper 400 to rotate, allowing the first inclined surface to slide and press against the second inclined surface, thus... The second inclined plane can drive the striking block 305 to move upward, which in turn drives the push rod 304 to move the fixed block 303 upward to compress the spring 302. When the scraper 400 rotates and the first inclined plane is separated from the second inclined plane, at this time, under the action of the spring 302, the spring 302 can push the fixed block 303 to move the push rod 304 downward, which in turn drives the push rod 304 to move the striking block 305 downward to strike the dispersing plate 306, thereby causing the dispersing plate 306 to vibrate, thus better preventing the dust suppressant from clogging the slot 500.

[0039] In actual use, a retaining ring is fixedly provided at the lower opening of the mounting cylinder 301, and the lower side of the fixing block 303 abuts against the upper side of the retaining ring, so that the fixing block 303 can be installed inside the mounting cylinder 301.

[0040] The fixing block 303 is adapted to the mounting cylinder 301, so that the fixing block 303 can move smoothly up and down inside the mounting cylinder 301, thereby enabling the fixing block 303 to compress the spring 302 better.

[0041] Specifically, the upper end of the push rod 304 is fixedly installed on the lower side wall of the fixing block 303, and the lower end is fixedly connected to the upper side wall of the striking block 305;

[0042] The mounting cylinder 301 is provided with multiple cylinders along the lower side of the can cover 201, so that the rotation of the scraper 400 can drive multiple striking blocks 305 to strike the dispersing plate 306 in sequence, thereby enabling the dispersing plate 306 to receive better striking vibration.

[0043] Combination Figures 4-6 As shown, in this embodiment, the stirring assembly includes a rotating cylinder 402 sleeved outside the rotating shaft 309. A plurality of stirring plates 406 are evenly arranged on the outer side wall of the rotating cylinder 402. A limiting block 507 is provided on the outer side wall of the rotating shaft 309 along its axial direction. A limiting groove is provided on the inner side wall of the rotating cylinder 402 for the insertion of the limiting block 507. A lifting component is also provided on the rotating shaft 309, which is used to drive the rotating cylinder 402 to move up and down.

[0044] In this embodiment, an annular groove 508 is provided on the outer side wall of the rotating cylinder 402 along its circumference. The lifting component includes a rotating column 509 sleeved on the outer side wall of the rotating shaft 309. A wave groove 504 with connected ends and a wave shape is provided on the outer side wall of the rotating column 509 along its circumference. A driving plate 502 is provided opposite to the outer side wall of the rotating column 509. A driving column 600 extending into the wave groove 504 is provided on the inner side wall of the driving plate 502. A connecting plate 505 is provided on the lower side wall of the driving plate 502. An annular block 506 that can be sleeved into the annular groove 508 is provided between the opposite connecting plates 505. A limiting component for limiting the driving plate 502 is also provided in the water storage cavity 300.

[0045] In actual use, the rotating column 509 is fixedly sleeved on the outer wall of the rotating shaft 309. The rotation of the rotating shaft 309 can drive the rotating column 509 to rotate, so that the rotating column 509 can drive the wave groove 504 to rotate. Through the setting of the limiting member, the limiting member can limit the driving plate 502, so that it will not rotate with the rotating column 509. In this way, the rotating column 509 can drive the driving column 600 to rise and fall along the wave groove 504, so that the driving column 600 can drive the corresponding driving plate 502 to rise and fall. The driving plate 502 can drive the two connecting plates 505 to drive the annular block 506 to rise and fall, so that the annular block 506 can drive the rotating cylinder 402 to rise and fall.

[0046] The connecting plate 505 is L-shaped, with one end fixedly connected to the lower side wall of the drive plate 502 and the other end fixedly connected to the annular block 506.

[0047] Specifically, the drive plate 502 is arc-shaped, and the drive column 600 is fixedly installed on the inner side wall of the drive plate 502;

[0048] In actual use, the outer wall of the drive plate 502 is provided with a lifting groove 503 along its height direction. The limiting member includes an L-shaped limiting plate 501. One end of the limiting plate 501 is fixedly connected to the lower side of the dispersion plate 306, and the other end extends out into the lifting groove 503. The limiting plate 501 is adapted to the lifting groove 503. The limiting plate 501 can limit the drive plate 502 so that the drive plate 502 will not rotate with the rotating column 509. The lifting groove 503 allows the drive plate 502 to rise and fall along the lifting groove 503 when the rotating column 509 rotates and drives the drive plate 502 to rise and fall.

[0049] In practical use, when preparing a dust suppressant mixture solution, an appropriate amount of water is first added to the water storage chamber 300 through the water inlet pipe 103. The servo motor 102 is then started, driving the rotating shaft 309 to rotate, which in turn drives the scraper 400 to rotate. Next, the dust suppressant is added to the water storage chamber 300 through the water inlet pipe 103, allowing it to remain on the dispersing plate 306. The rotating scraper 400 scrapes the dust suppressant on the dispersing plate 306, allowing it to disperse through multiple slots 500 into the water storage chamber 300 located below the dispersing plate 306. Simultaneously, the rotation of the scraper 400 drives the striking element to... The dispersion plate 306 is struck to cause it to vibrate, thus effectively preventing the dust suppressant from clogging the slot 500. Simultaneously, the servo motor 102 drives the rotating shaft 309 to rotate, which in turn drives the rotating column 509 to rotate, thereby driving the wave groove 504 to rotate. The limiting component restricts the drive plate 502, preventing it from rotating with the rotating column 509. This allows the annular block 506 to move the rotating cylinder 402 up and down, ensuring that the water and dust suppressant in the water storage chamber 300 are thoroughly stirred. The prepared dust suppressant solution is then transported to the fog cannon body 10 through the connecting hose 101.

[0050] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
