Description

Technical Field

[0001] This utility model relates to the field of fully mechanized mining equipment technology, specifically to a dust removal device for pipelines in fully mechanized mining faces with adjustable dimensions. Background Technology

[0002] The full name of a fully mechanized longwall mining face is a longwall mining face equipped with hydraulic supports, high-power scraper conveyors, and double-drum coal mining machines. Its processes include coal breaking, coal loading, coal transportation, support, and goaf treatment. In underground coal mining, the mine dust generated not only seriously affects the safe production of coal mines, but also poses a serious threat to the health of miners. Especially when working in a high-concentration coal dust environment for a long time, miners who inhale large amounts of dust will develop pulmonary fibrosis and suffer from pneumoconiosis. Moreover, pneumoconiosis has a slow onset, a long incubation period, and an irreversible pathological process. Therefore, it is necessary to reduce dust in the fully mechanized longwall mining face and remove dust from pipelines to reduce the dust concentration in the fully mechanized longwall mining face and improve the working environment.

[0003] In existing technologies, dust removal operations on working face pipelines still widely employ brush cleaning methods. This involves driving brushes to reciprocate across the outer surface of the pipeline, removing adhering dust and impurities through physical friction. However, when the brushes contact and brush the pipeline surface, the tightly adhered dust is detached under external force. This detached dust is not effectively collected or controlled, but instead diffuses directly into the surrounding air, forming a large amount of suspended particulate matter. Since working faces are typically relatively enclosed spaces with limited air circulation, the suspended dust cannot be quickly expelled from the working environment, resulting in widespread dispersion. Furthermore, this dispersed dust will quickly settle back onto the cleaned or uncleaned pipeline surfaces, causing secondary pollution and significantly reducing the efficiency of dust removal operations. Therefore, we propose an adjustable-size dust removal device for fully mechanized mining face pipelines. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-size dust removal device for pipelines in fully mechanized mining faces to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-size dust removal device for pipelines in a fully mechanized mining face, comprising a slide rail, two arc-shaped connecting plates, and two brushes. A slider one is installed on the outer left side of the slide rail, and a slider two is installed on the outer right side of the slide rail. A mounting plate one is fixedly connected to the bottom of slider one, and a connecting block is fixedly connected to the top of the arc-shaped connecting plates. The device also includes:

[0006] The bottom of the slider two is fixedly connected to the mounting plate two. The mounting plate two has an installation groove inside. An air pump is fixedly connected inside the mounting groove, and a push rod is fixedly connected to the output end of the air pump. A push block is fixedly connected to one end of the push rod. Four rotating blocks one are fixedly connected to the outside of the push block. A rotating rod is rotatably connected inside the rotating block one. A rotating block two is installed at the other end of the rotating rod. An extension block is fixedly connected to the outside of the rotating block two.

[0007] A water pump is fixedly connected to the bottom of the mounting plate 2, and a connecting pipe is fixedly connected to the output end of the water pump. A diversion box is fixedly connected to one end of the connecting pipe. Two diversion pipes 1 are fixedly connected to both sides of the diversion box. A rinsing nozzle is fixedly connected to the other end of the diversion pipe 1. Two diversion pipes 2 are fixedly connected to the bottom of the diversion box. An atomizing nozzle is fixedly connected to the other end of the diversion pipe 2.

[0008] The mounting plate has two sliding connection plates inside, and a reinforcing plate is fixedly connected to the bottom of the limiting plate. Two limiting bolts are installed inside the limiting plate. The mounting plate has a sliding groove inside, and two limiting rods are fixedly connected inside the sliding groove.

[0009] Among them, a limit block is installed at the bottom of the arc-shaped connecting plate, and a limit rod is slidably connected inside the limit block.

[0010] The push block is slidably connected inside the second mounting plate, and four limit rods are fixedly connected to the outside of the second mounting plate.

[0011] The top of the rinsing nozzle is fixedly connected to the bottom of the second mounting plate, and the top of the atomizing nozzle is fixedly connected to the bottom of the extension block.

[0012] The connecting block is externally slidably connected to the inside of the mounting plate, and the brush is externally fixedly connected to the inside of the arc-shaped connecting plate.

[0013] The bottom of the reinforcing plate is fixedly connected to the top of the arc-shaped connecting plate, and the limiting bolt is threadedly connected inside the mounting plate.

[0014] This utility model has at least the following beneficial effects:

[0015] When this utility model is in use, the arc-shaped connecting plate drives the brush to first physically clean the surface of the pipeline and initially remove the attached dust; the subsequent flushing nozzle uses water flow to perform a second flushing on the cleaned pipeline surface to remove the dust and impurities remaining on the brush and prevent dust from adhering and remaining.

[0016] The atomizing nozzles atomize water and spray it around the pipeline, forming a gas-liquid mixing barrier. This can capture suspended dust that is released during cleaning and rinsing, preventing it from spreading over a large area in the enclosed working surface. With the diversion design, the atomization range can cover the top and surrounding areas of the pipeline, improving dust reduction efficiency and reducing secondary pollution.

Slider 101 is mounted on the outer left side of the slide rail 1, and its bottom is fixedly connected to the mounting plate 103. It can slide along the slide rail 1, driving the mounting plate 103, the arc-shaped connecting plates 105, and the brushes 106 to move, providing the brushes 106 with the power to clean the pipeline. The device also includes:

[0027] The bottom of slider 2 102 is fixedly connected to mounting plate 2 4. Mounting plate 2 4 has a mounting groove 401 inside. Air pump 402 is fixedly connected inside mounting groove 401. Push rod 403 is fixedly connected to the output end of air pump 402. Push block 404 is fixedly connected to one end of push rod 403. Four rotating blocks 1 405 are fixedly connected to the outside of push block 404. Rotating rod 406 is rotatably connected inside rotating block 1 405. Rotating block 2 407 is installed at the other end of rotating rod 406. Extension block 408 is fixedly connected to the outside of rotating block 2 407. Push block 404 is slidably connected inside mounting plate 2 4. Four limiting rods 3 409 are fixedly connected to the outside of mounting plate 2 4. Mounting plate 2 4 is fixedly connected to the bottom of slider 2 102 and has a mounting groove 401 inside, providing a mounting platform for air pump 402, water pump 5, and diversion box 502.

[0028] A water pump 5 is fixedly connected to the bottom of mounting plate 2 4, and a connecting pipe 501 is fixedly connected to the output end of the water pump 5. A diversion box 502 is fixedly connected to one end of the connecting pipe 501. Two diversion pipes 1 503 are fixedly connected to both sides of the diversion box 502. A rinsing nozzle 504 is fixedly connected to the other end of the diversion pipe 1 503. Two diversion pipes 2 505 are fixedly connected to the bottom of the diversion box 502. An atomizing nozzle 506 is fixedly connected to the other end of the diversion pipe 2 505. The top of the rinsing nozzle 504 is fixedly connected to the bottom of mounting plate 2 4, and the top of the atomizing nozzle 506 is fixedly connected to the bottom of extension block 408. The diversion box 502 is fixedly connected to the connecting pipe 501, with diversion pipes 1 503 connected to both sides and diversion pipes 2 505 connected to the bottom. It receives water delivered by the connecting pipe 501 and diverts the water to different nozzles to achieve water distribution for rinsing and atomizing functions.

[0029] The mounting plate 103 has two sliding limit plates 107 inside, and a reinforcing plate 108 is fixedly connected to the bottom of the limit plate 107. Two limit bolts 109 are installed inside the limit plate 107. The mounting plate 103 has a sliding groove 2 inside, and two limit rods 201 are fixedly connected inside the sliding groove 2. The connecting block 104 is externally slidably connected to the inside of the mounting plate 103. The brush 106 is externally fixedly connected to the inside of the arc-shaped connecting plate 105. The bottom of the reinforcing plate 108 is fixedly connected to the top of the arc-shaped connecting plate 105. The limit bolts 109 are threadedly connected to the inside of the mounting plate 103. The limit bolts 109 are threadedly connected to the inside of the mounting plate 103, penetrate the limit plate 107, and fix the position of the limit plate 107 when tightened to prevent the arc-shaped connecting plate 105 from shifting during dust removal.

[0030] A limiting block 3 is installed at the bottom of the arc-shaped connecting plate 105, and a second limiting rod 301 is slidably connected inside the limiting block 3. The limiting block 3 is installed at the bottom of the arc-shaped connecting plate 105, and the second limiting rod 301 is slidably connected inside. It cooperates with the second limiting rod 301 to further guide the movement of the arc-shaped connecting plate 105 and enhance the stability during the adjustment process.

[0031] The working principle of this utility model is as follows: For pipelines of different sizes, firstly, by adjusting the limiting bolt 109 inside the mounting plate 103, the fixed restriction on the limiting plate 107 is released. The limiting plate 107 slides along the limiting rod 201 in the slide groove 2, which drives the bottom fixed connection of the reinforcing plate 108 and the arc-shaped connecting plate 105 to move synchronously, so that the distance between the two arc-shaped connecting plates 105 increases or decreases to adapt to pipelines of different diameters. The limiting block 3 at the bottom of the arc-shaped connecting plate 105 slides and engages with the limiting rod 301, which guides and limits the movement of the arc-shaped connecting plate 105 to prevent displacement. After the adjustment is completed, the limiting bolt 109 is tightened again to fix the limiting plate 107 and ensure that the position of the arc-shaped connecting plate 105 is stable.

[0032] After the device is installed and adapted, the slider 101 slides along the slide rail 1, driving the mounting plate 103 and the arc-shaped connecting plate 105 to move synchronously. The brush 106 fixed inside the arc-shaped connecting plate 105 contacts the outside of the pipeline. During the sliding process, it cleans the dust, coal dust and other impurities on the surface of the pipeline to achieve preliminary dust removal. The connecting block 104 firmly connects the arc-shaped connecting plate 105 and the mounting plate 103 to ensure that the brush 106 fits tightly with the surface of the pipeline and improves the cleaning effect.

[0033] Slider 2 102 slides synchronously along slide rail 1 with slider 1 101, driving mounting plate 2 4 to move closely following the cleaning area of ​​brush 106. Water pump 5 at the bottom of mounting plate 2 4 obtains water through external pipe and delivers water to distribution box 502 through connecting pipe 501. Distribution box 502 distributes water to flushing nozzle 504 through distribution pipe 1 503. Flushing nozzle 504 flushes the surface of the pipeline after brush 106 has cleaned it, removing residual dust and impurities and enhancing the dust removal effect. At the same time, distribution box 502 delivers water to atomizing nozzle 506 through distribution pipe 2 505. Atomizing nozzle 506 atomizes the water and sprays it on the top and surrounding areas of the pipeline to suppress dust diffusion and play a dust reduction role.

[0034] To adapt to the atomization and dust suppression requirements of pipelines of different sizes, the air pump 402 in the mounting slot 401 can be activated. The air pump 402 drives the push rod 403 to extend and retract, causing the push block 404 to slide inside the mounting plate 4. The push block 404 drives the rotating rod 406 to rotate through the rotating block 405. The rotating block 407 at the other end of the rotating rod 406 pushes the extension block 408 to expand outward or contract inward. The atomizing nozzle 506 at the bottom of the extension block 408 moves with it, expanding or shrinking the atomization range to ensure effective coverage of the surrounding area of ​​pipelines of different diameters.

[0035] Example 2

[0036] Please see Figures 4 to 6 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the limiting rod 409 on the outside of the mounting plate 4 limits the movement of the extension block 408 to prevent excessive expansion. The first diversion pipe 503 and the second diversion pipe 505 are designed with flexible hoses, which can be flexibly stretched with the movement of the extension block 408 to avoid pipe breakage due to stretching.
