Description

Technical Field

[0001] The invention relates to the technical field of mine dust removal, and in particular to an environmentally friendly tunnel dust removal device used in coal mining. Background Art

[0002] In the process of coal mining, the dust problem in the tunnel has always been an important problem that plagues the industry. Dust not only seriously pollutes the working environment, but also poses a great threat to the health of miners. Long-term exposure to high-concentration dust environments makes miners susceptible to occupational diseases such as pneumoconiosis and respiratory diseases, and may even cause safety accidents such as dust explosions. Therefore, effectively controlling the dust concentration in the tunnel is not only necessary to protect the health and safety of miners, but also an important part of improving coal mining efficiency.

[0003] Traditional methods of dust removal in tunnels mainly include water spraying, ventilation and mechanical filtration. However, these methods have many limitations in practical applications: Water spraying for dust suppression: Water spraying for dust suppression is to suppress the spread of dust by spraying water mist into the tunnel. Although this method is simple and easy to implement, its dust suppression effect is limited, especially when the dust concentration is high or the tunnel space is large, the water mist is difficult to cover the entire area. In addition, water spraying for dust suppression consumes a lot of water resources and easily makes the tunnel slippery, increasing safety hazards. At the same time, water and dust may form mud after mixing, causing secondary pollution and increasing the difficulty of cleaning.

[0004] Ventilation and dust removal: Ventilation and dust removal is to use fans to discharge dusty air out of the tunnel to reduce dust concentration. Although this method can improve air quality to a certain extent, its effect is limited by the power of the fan and the ventilation conditions of the tunnel. In poorly ventilated tunnels, dust easily accumulates and is difficult to completely remove. In addition, ventilation and dust removal consumes a lot of electricity, has high operating costs, and the noise generated by the fan operation will also have a negative impact on the working environment.

[0005] Mechanical filtration: Mechanical filtration is to trap dust particles in the air through filtering equipment to achieve the purpose of dust removal. Although this method can effectively remove dust, traditional filtering equipment is usually complex in structure and inconvenient to install and maintain. The filter components are easily clogged and need to be replaced frequently, which increases the operating cost. In addition, mechanical filtering equipment has high energy consumption, and the filtering efficiency will drop significantly when dealing with high concentrations of dust.

[0006] With increasingly stringent environmental regulations and mining companies' emphasis on safe production, traditional dust removal methods can no longer meet the needs of modern coal mining. Summary of the invention

[0071] It should be noted that the vibration-falling point 30522 is disc-shaped, and the raised portion 30523 is spherical. When the non-woven fabric layer 30521 and the dust barrier layer 3053 are sucked up and fall due to negative pressure, the non-woven fabric layer 30521 adheres to the outer ring bracket 30361, and the dust barrier layer 3053 at the bottom vibrates and repeatedly contacts the vibration-falling layer 3052, so that the raised portion 30523 contacts the dust barrier layer 3053, and the dust adsorbed on the dust barrier layer 3053 falls and is collected on the dust collecting component 306.

[0072] Furthermore, in order to prevent the collected dust from being sucked away by the fan 302 again, the dust collecting component 306 is a collecting plate that moves in the dust collecting cover 301, and a baffle plate is provided on the collecting plate, and a limiting baffle is provided in the dust collecting cover 301 to cooperate with the baffle plate, so that the dust is collected behind the baffle plate and is no longer sucked by the fan 302.

[0073] Specifically, the steps of the environmentally friendly tunnel dust removal for coal mining are as follows: the mobile base 10 moves in the tunnel, and after moving to the position where dust reduction and dust removal is required, the mobile base 10 is fixed. Then, the adapter mechanism 205 is installed on the positioning mechanism 202, and the filter mechanism 206 is installed on the adapter mechanism 205, and the spray mechanism 207 is movably plugged into the extension pipe 2071 connected to the water pipe 203, and the spray mechanism 207 is engaged in the adapter mechanism 205.

[0074] The assembly steps are as follows: first, the connecting pipe frame 2051 is installed on the adapter component 2023, the adapter component 2023 is installed on the base 2021 through a bearing, and a positioning hole is provided on the adapter component 2023, the positioning shaft 2057 is inserted into the corresponding positioning hole, and the sealing gasket 2056 is inserted into the positioning tube 2022, and the assembly of the connecting pipe frame 2051 and the base 2021 is completed. Then, the filter mechanism 206 is installed on the ventilation pipe 2053, first, the inner fastening plate 2062 with the filter element 2063 is installed on the outer through pipe 2061, and then the outer through pipe 2061 is correspondingly inserted into the ventilation pipe 2053, and the assembly of the filter mechanism 206 and the ventilation pipe 2053 is completed. Finally, the spray mechanism 207 is installed on the extension tube 2071. First, when installing the adapter mechanism 205, the connecting pipe frame 2051 is sleeved on the outside of the extension tube 2071, and the connecting pipe 2074 is threadedly connected to the clamping seat 2072. At the same time, the clamping seat 2072 is set on the extension tube 2071 through a bearing. Then the connecting pipe 2074 with the spray pipe 2076 is installed on the extension tube 2071.

[0075] The steps of dust reduction and dust removal are: operate the driving component 2042, the driving component 2042 drives the transmission component 2043 to rotate through the reducer, the transmission component 2043 and the driven component 2054 are meshed and connected to drive the connecting pipe rack 2051 to rotate, and when the connecting pipe rack 2051 rotates, the positioning card plate 2073 on the card seat 2072 is engaged with the inner wall of the connecting pipe rack 2051 and rotates with it, so that the connecting pipe 2074 rotates. At this time, the water pump is operated to transport water to the connecting pipe 2074 and the branch pipe 2075 through the water pipe 203, and finally sprayed out through the atomizing nozzle installed on the spray pipe 2076, and the atomizing nozzle rotates to spray, and the atomization range is larger to enhance the dust reduction effect. During the dust reduction process, the fan 302 is operated synchronously, and the negative pressure generated by the operation of the fan 302 sucks the dust into the filter mechanism 206.

[0076] The steps of filtering and collecting dust are as follows: dust is sucked into the external pipe 2061, and the dust is first filtered by the third filter component 20633, the second filter component 20632 and the first filter component 20631, and then enters the dust collecting housing 301, and the dust is intercepted and sucked by the baffle 304. During the suction process, the fan 302 sucks the dust blocking mechanism 305 to rise, and the dust blocking mechanism 305 is intercepted by the gear mechanism 3036, and the dust is adsorbed on the dust blocking mechanism 305. At this time, the second driving component 3031 is synchronously operated, and the second driving component 3031 drives the conveyor belt 3033 to rotate when it is running, and the conveyor belt 3033 drives the top rod 3034 to move when it rotates, and the top rod 3034 abuts against the buffer 3035 when it moves, so that the buffer rod 30351 moves downward, and the buffer rod 30351 pushes the dust blocking mechanism 305 downward. The raised portion 30523 on the shaking-off point 30522 abuts against the dust blocking layer 3053 , shaking off the dust on the dust blocking layer 3053 . The shaken-off dust falls down and falls into the dust collecting component 306 , where the dust is collected and stored.
