Description

Technical Field

[0001] This application relates to the technical field of coal mine safety equipment, and more specifically, to a dust suppression device for coal mine construction sites. Background Technology

[0002] Coal mining operations generate a large amount of dust that floats in the air. Working in dusty mine shafts can seriously affect the health of miners and reduce visibility, thus impacting work efficiency. Therefore, it is necessary to use coal mine ventilation and dust removal devices to treat the air in coal mining areas.

[0003] Spray dust suppression is a common method used at coal mine construction sites, where water mist combines with airborne dust to fall. However, the inventors recognized that common coal mine spray equipment, such as the automatic spray dust suppression device of model ZP127, mainly involves bending water pipes into specific shapes at the inlet and outlet positions and fixing them to the mine roof. Then, spray nozzles are installed on the water pipes to spray water mist downwards to prevent dust from spreading. However, the fixed water pipes result in a limited water mist coverage area and are not convenient to move for dust suppression.

[0004] Based on the above problems, we provide a dust suppression device for coal mine construction sites. Summary of the Invention

[0005] To address the problems mentioned in the background art, this application provides a dust suppression device for coal mine construction sites.

[0010] In some embodiments, the support plate is also provided with multiple air holes and an exhaust fan is installed in the air holes to blow away the water mist and increase the coverage of the water mist.

[0011] In some embodiments, the two bottom ends of the scissor lift frame near the side of the box frame are hinged to the box frame, and the scissor lift frame is provided with multiple support ribs, which are connected between adjacent horizontally symmetrical ends. A fixing member is also installed in the middle of the support rib located at the bottom outermost position.

[0015] In some embodiments, the inner walls on both sides of the box frame are provided with embedded grooves, the rollers are rotatably installed at the upper and lower ends of the embedded grooves, and the timing belt is also provided with timing blocks, which are fixedly installed on the support platform.

[0016] In summary, in the technical solution of this application embodiment, the spraying component is installed on the vehicle body, which can carry out spraying operations during movement, making it convenient to move to areas where dust is raised for operation. In addition, the vehicle body is also equipped with a panel frame, in which the spraying component can be stored when not in operation, which plays a protective role and can also reduce the space occupied.

[0019] The following is in conjunction with the appendix Figures 1 to 10 The present invention will be described in further detail below.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] It should be noted that the accompanying drawings are schematic and not to scale. For clarity and convenience, the relative dimensions and proportions of the parts shown are exaggerated or reduced in size; all dimensions are merely illustrative and not limiting. Furthermore, the same reference numerals are used for the same structures, elements, or fittings appearing in more than two drawings to indicate similar features.

[0022] In related technologies, such as the automatic spray dust suppression device of model ZP127, the water pipe is bent and fixed at the top of the mine, and multiple nozzles are installed on the water pipe to spray water mist downwards to prevent dust from spreading. In order to flexibly implement dust suppression in various areas of the coal mine, refer to Figures 1 to 10 As shown, the dust suppression device of this application includes a spray component 3 and a vehicle body 1. The spray component 3 is mounted on the vehicle body 1, and the vehicle body 1 can easily move the spray component 3, and the spray dust suppression operation can be carried out during the movement. In this embodiment, the spray component 3 includes a support frame 301 and a support plate 305 hinged to both sides of the support frame 301. The spray pipe 308 is bent and attached to the edge of the support plate 305, and is fixed to the support plate 305 by a fastener 310. A water tank 12 is also installed on the vehicle body 1. A water pump 312 is provided on the top of the water tank 12. The input end of the water pump 312 extends into the water tank 12 to facilitate water pumping from the water tank 12. A hose 311 is also installed between the output end of the water pump 312 and the spray pipe 308 to facilitate water delivery to the spray pipe 308. Water mist can be sprayed to both sides of the vehicle body 1 through multiple atomizing nozzles 309 provided on the spray pipe 308, thereby combining with dust in the air to reduce dust. Based on this, in order to increase the diffusion range of the sprayed water mist, multiple air holes are also provided in the support plate 305, and an exhaust fan 306 is installed in the air holes. With the cooperation of the exhaust fan 306, the water mist can be blown outward or upward to spread, thereby covering a larger area. In addition, when the exhaust fan 306 blows the airflow, according to the characteristics of fluid flow, the slow fluid will move closer to the fast fluid, and the fast-flowing water mist airflow will also attract air and bring dust closer, thereby quickly mixing the dust in the air with the water mist, achieving the effect of rapid dust suppression.

[0023] Furthermore, in order to carry out dust suppression operations more flexibly, refer to Figure 3 , 4 As shown in Figures 7 and 10, a slider 302 is slidably installed inside the support frame 301, and vertical grooves for the slider 302 to pass through are provided on both sides of the support frame 301. The two ends of the slider 302 extending outside the support frame 301 are also hingedly installed with diagonal braces 307. The top end of the diagonal braces 307 is hingedly connected to the support plate 305. During the up and down sliding of the slider 302, it can cooperate with the diagonal braces 307 to push the support plate 305 to rotate around the top of the support frame 301, so that the support plate 305 maintains a certain slope. Specifically, during use, when the dust area has a high coverage height, the support plate 305 can be flipped to a near-horizontal position. At this time, the exhaust fan 306 and the atomizing nozzle 309 work together to blow the water mist as high as possible, making it easier to combine with the dust at higher levels for dust suppression. When the dust area has a wide coverage width, the support plate 305 can be flipped to a near-vertical position. At this time, the exhaust fan 306 will blow the water mist as far to the sides as possible, covering a wider area. The system can be flexibly adjusted according to the dust area conditions. In this embodiment, a retraction drive 304 is also installed on the top of the support frame 301. The output shaft of the retraction drive 304 extends into the support frame 301 and is connected to a lifting screw 303. The slider 302 is threadedly fitted onto the screw 303. The retraction drive 304 can drive the lifting screw 303 to rotate. The position of the slider 302 can be adjusted by the threaded engagement between the lifting screw 303 and the slider 302, which facilitates adjustment in conjunction with the support plate 305.

[0024] For easy storage of the spray component 3, refer to Figure 1 , 2 As shown in Figures 3 and 6, a panel frame 11 is also installed on the vehicle body 1. The support at the bottom of the spraying component 3 is slidably installed in the panel frame 11, and a lifting component 2 is installed between the vehicle body 1 and the support. With the cooperation of the lifting component 2, the support can be pushed to slide in the panel frame 11. When not in operation, the lifting component 2 retracts, driving the support and the spraying component 3 to slide into the panel frame 11. The panel frame 11 can protect the spraying component 3, and after storage, it can reduce the space occupied and be stored. Specifically, the lifting component 2 includes a scissor lift frame 201. The two bottom ends of the scissor lift frame 201 near the side of the side panel frame 11 are hinged to the side panel frame 11 for limiting and fixing. The scissor lift frame 201 is provided with multiple support ribs 202, which are connected between horizontally symmetrical adjacent ends. With the cooperation of the support ribs 202, the overall stability of the scissor lift frame 201 can be maintained. A fixing component is also installed in the middle of the support rib 202 located at the bottom outermost position. A lifting drive component 203 is also installed on the vehicle body 1. The output shaft of the lifting drive component 203 is connected to the fixing component. In use, the lifting drive component 203 will cooperate with the fixing component to push the support rib 202 at the bottom outermost position to slide, thereby pushing the scissor lift frame 201 upward to push the support platform to slide.

[0025] In this embodiment, multiple end positions of the scissor lift frame 201 near the side of the box frame 11 are connected to limit seats 205. The same limit rod 206 is slidably fitted on multiple limit seats 205 with the same projection position. Limit grooves 1101 are opened on both sides of the inner wall of the box frame 11. The limit rod 206 is fixedly installed in the limit groove 1101. The limit rod 206 installed in the limit groove 1101 can keep the multiple limit seats 205 in a limited position, thereby further maintaining the stability of the scissor lift frame 201.

[0026] During use, the sprayed water mist combines with dust in the air and falls under the influence of gravity. Inevitably, some dust particles fall onto the spray component 3. After operation stops, the dust particles can solidify and clog the atomizing nozzle 309. Therefore, it is necessary to clean the dust particles from the spray component 3, referring to... Figure 1 , 2 As shown in 3, 4, 5, and 9, the cleaning component 4 also includes two rollers 401 arranged side by side, with transmission wheels 402 mounted on both ends of the rollers 401. The same synchronous belt 403 is mounted on the two transmission wheels 402 with the same projection position. A roller sleeve 404 is mounted on the upper roller 401, and multiple cloth brushes 405 for cleaning the spray component 3 are provided on the roller sleeve 404. In this embodiment, the transmission wheel 402 and the timing belt 403 need to be engaged by teeth and kept taut to ensure that the transmission wheel 402 and the timing belt 403 maintain precise synchronous engagement. Specifically, in order to drive the roller shaft 401 to rotate, a timing block 406 is also provided on the timing belt 403. The timing block 406 is fixedly installed on the support platform. At the beginning or end of the dust suppression operation, the lifting component 2 will push the spray component 3 to slide up or down. At this time, the support platform will cooperate with the timing block 406, thereby pulling the timing belt 403 to slide. With the cooperation of the timing belt 403 and the transmission wheel 402, the roller shaft 401 can be driven to rotate. When the roller shaft 401 pushes the roller sleeve 404 to rotate quickly, the cloth brush 405 on it will be flung outward by centrifugal force, so as to facilitate contact with the spray component 3 and clean the dust particles on the surface of the spray component 3. In addition, to increase the cleaning effect, the spray component 3 needs to maintain the spraying of water mist during the upward or downward sliding process. When the cloth brush 405 cleans the dust particles on it, the sprayed water mist can also carry away the dust particles. Subsequently, the dust particles will flow down along the inner wall of the box frame 11. Furthermore, in order to drain the water and dust particles on the vehicle body 1, the vehicle body 1 can be made with a hollow design.

[0027] In this embodiment, the inner walls on both sides of the panel frame 11 are also provided with embedded grooves 1102. The roller shaft 401 is rotatably installed at the upper and lower ends of the embedded groove 1102, which can conveniently hide the roller shaft 401 in the panel frame 11, thereby avoiding the movement trajectory of the support platform and ensuring that the roller sleeve 404 is fitted to the support platform, ensuring that the cloth brush 405 on the roller sleeve 404 can contact the spraying component 3 to complete the cleaning work.
