Description

Technical Field

[0001] This utility model belongs to the technical field of coal mining equipment, and more specifically, it relates to noise reduction and dust removal equipment for coal mining. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. They are generally divided into underground coal mines and open-pit coal mines. Coal mines are reasonable spaces excavated by humans when digging into geological layers rich in coal. During the coal mining process, the air at the site is filled with dust, and the noise from mining can easily affect the surrounding environment. Therefore, noise reduction and dust removal equipment is needed to improve these situations.

[0003] Based on the above, most existing noise reduction and dust removal equipment requires mobile water spraying to prevent dust from spreading outwards, which makes it difficult to completely suppress the spread of dust. Moreover, the noise generated during mining cannot be isolated, which can easily cause noise pollution in the surrounding area. Utility Model Content

[0004] To address the aforementioned technical problems, this disclosure relates to noise reduction and dust removal equipment for coal mining. It solves the issues that current noise reduction and dust removal equipment struggles to comprehensively suppress dust dispersion and cannot isolate noise generated during mechanical coal mining. This equipment not only isolates the mining site from the outside world, effectively preventing external personnel from interfering, but also, through its dust suppression spray structure, prevents dust dispersion and allows for the recycling of some water from lower spray angles, reducing water waste. Furthermore, the assembly components accelerate installation, reduce operational difficulty, and facilitate subsequent disassembly.

[0005] This utility model of noise reduction and dust removal equipment for coal mining is achieved through the following specific technical means:

[0041] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0042] This utility model provides a noise reduction and dust removal device for coal mining, including a fixed base 1 and a dust reduction spray structure 2;

[0043] A connecting support frame 101 is fixedly connected to the top of the fixed base 1. A first enclosure 102 is provided on the top of the connecting support frame 101. A first sound insulation panel 104 and a second sound insulation panel 1041 are provided on both sides inside the first enclosure 102. A sound-absorbing panel 105 is provided between the first sound insulation panel 104 and the second sound insulation panel 1041. A second enclosure 103 with the same structure is provided on one side of the first enclosure 102. Fixed brackets 201 are fixedly connected to the top ends of the first enclosure 102 and the second enclosure 103. A water supply pipe 202 is fixedly installed inside the fixed bracket 201. A water distribution pipe 2021 is fixedly connected, and an atomizing nozzle 2022 is fixedly installed on the water distribution pipe 2021. The water supply pipes 202 of the first enclosure 102 and the second enclosure 103 are fixedly connected by a connecting threaded sleeve 203. A water collection frame 204 is provided at the front end of the first enclosure 102 and the second enclosure 103. A guide wedge plate 2041 is provided on both sides inside the water collection frame 204. A trough 2042 is provided in the middle of the water collection frame 204. Support corner plates 2043 are provided on both sides of the bottom of the water collection frame 204. A water delivery trough 205 is provided at the bottom of the water collection frame 204. One end of the water delivery trough 205... A first sealing groove 2051 is provided on the inner side, and a connecting T-frame 206 is provided between the water supply troughs 205. Second sealing grooves 2061 are provided on both sides of the connecting T-frame 206. Sealing gaskets 2062 are installed inside the first sealing groove 2051 and the second sealing groove 2061. The connecting T-frame 206 is installed between the water supply troughs 205 by fixing bolts 2063. The water supply pipe 202 on the left side of the first enclosure 102 is connected to a water source, and the water flows into the distribution pipe 2021 through the water supply pipe 202, and is finally sprayed out through the atomizing nozzle 2022, thereby controlling dust. Neutralization treatment prevents dust from spreading. The first sound insulation board 104 and the second sound insulation board 1041 effectively reduce the propagation of sound. The sound absorption board 105 can isolate the propagation of sound. When the atomizing nozzle 2022 sprays water, some water will flow into the water collection frame 204 due to the low angle. After the atomized water droplets condense, they flow into the water delivery trough 2042 through the inclined surface of the guide wedge plate 2041. One end of the water delivery trough 205 is connected to the water outlet. Finally, the water flows back to the water outlet through the water delivery trough 205, reducing the waste of water resources.

[0044] Example 2: Based on Example 1, wherein, as Figure 5 and Figure 6 As shown, an assembly assembly 3 is provided between the first enclosure 102 and the second enclosure 103. The assembly assembly 3 includes an assembly frame 301 and a connecting slot 3011. The assembly frame 301 is fixedly connected to the right side of the first enclosure 102. The connecting slot 3011 is provided inside the assembly frame 301. The sliding support hole 302 is provided inside the assembly frame 301. A connecting pin 3021 is slidably installed inside the sliding support hole 302. A connecting protrusion ring 3022 is fixedly connected to the outside of the connecting pin 3021. A reset groove 3023 is provided inside the assembly frame 301 outside the sliding support hole 302. A spring 3024 is provided inside the reset groove 3023. The end of the connecting pin 3021 passes through the assembly frame 301 and is fixedly connected to the outer pull rod 3025. The left side of the second enclosure 103... An assembly plate 303 is fixedly connected in the middle. The assembly plate 303 is fitted into the connecting slot 3011. The assembly plate 303 has a connecting hole 3031. The connecting pin 3021 is inserted into the connecting hole 3031. By pulling the pull rod 3025, the connecting pin 3021 is moved. Then, the assembly plate 303 is inserted into the connecting slot 3011. Then, the pull rod 3025 is released. When the connecting pin 3021 moves, it causes the connecting protrusion ring 3022 to compress the spring 3024 in the reset groove 3023, causing the spring 3024 to undergo elastic deformation. Under the reaction force of the spring 3024, the connecting protrusion ring 3022 is pushed to move. The connecting protrusion ring 3022 drives the connecting pin 3021 to reset and insert into the connecting hole 3031, thus completing the connection.

[0045] The specific usage and function of this embodiment are as follows:

[0046] In this invention, the connecting pin 3021 is first moved by pulling the lever 3025. Then, the mounting plate 303 is inserted into the connecting slot 3011. The lever 3025 is then released. As the connecting pin 3021 moves, it causes the connecting ring 3022 to compress the spring 3024 within the reset groove 3023, resulting in elastic deformation of the spring 3024. Under the reaction force of the spring 3024, the connecting ring 3022 is pushed to move, causing the connecting ring 3022 to reset and insert the connecting pin 3021 into the connecting hole 3031. This completes the connection between the first enclosure 102 and the second enclosure 103, accelerating the installation of the noise reduction and dust removal equipment. To improve efficiency, reduce operational difficulty, and facilitate subsequent disassembly, the water supply pipe 202 on the left side of the first enclosure 102 is connected to a water source. The water then flows into the distribution pipe 2021 through the water supply pipe 202 and is finally sprayed out through the atomizing nozzle 2022 to neutralize dust and prevent dust from spreading. When the atomizing nozzle 2022 sprays water, some water will flow into the water collection frame 204 due to the low angle. After the atomized water droplets condense, they flow through the trough 2042 into the water delivery trough 205 under the inclined surface of the guide wedge plate 2041. One end of the water delivery trough 205 is connected to the water outlet, and finally the water flows back to the water outlet through the water delivery trough 205, reducing water waste.
