Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a dust removal device for mine management. Background Art

[0002] In the field of mining, the daily mining work will cause a large amount of dust in the air of the mine, which seriously affects the air quality of the mine and thus affects the health of the workers in the mine. Therefore, dust removal equipment is needed in the mine to remove dust from the air of the mine. The most effective dust removal method is to use dust removal equipment to sprinkle water for dust removal. When the water droplets fall, they can bring down the dust floating in the air.

[0003] For example, Chinese patent CN220167980U discloses a dust removal spraying device for mine environmental management, which includes a water storage tank, a water pumping box provided at the top of the water storage tank, a telescopic bellows fixedly connected to one side of the bottom of the water pumping box, the telescopic bellows passing through the top of the water storage tank and extending to the interior of the water storage tank, and the water pumping box is raised to a suitable height according to environmental requirements for spraying dust removal. However, during the dust removal process, the above-mentioned device adsorbs dust by spraying water, and the dust is driven down by the water droplets. After the dust is driven down by the water droplets, the dust adheres to the ground due to the evaporation of water. Due to the complex environment of the mine and the large number of engineering vehicles, the settled dust may be blown up again by the wind or the movement of the vehicles, forming secondary dust, which not only reduces the dust removal effect, but also may cause greater pollution to the surrounding environment.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

In addition, in specific applications, the above-mentioned spraying rod 308 can spray upward or downward when spraying the salt solution, so that After absorbing the dust, the salt solution can fall into the reflux trough 4; the bottom end of the column 301 is fixedly connected to the inner bottom end of the box body 2, and limited sliding holes 3011 are provided on both sides of the column 301; connecting blocks 3021 that cooperate with the limited sliding holes 3011 are provided on both sides of the bottom of the lifting column 302, and the bottom end of the connecting block 3021 is provided with an electric telescopic rod 3022, and a threaded hole 3023 that cooperates with the threaded rod 303 is provided in the middle part of the top of the lifting column 302, thereby realizing the spraying of the salt solution, and the dust can be absorbed by the sprayed salt solution, and the spraying rod 308 can be driven by the electric telescopic rod 3022 and the drive motor 306 to perform multi-level height adjustment, and the position of the spraying rod 308 can be flexibly adjusted according to the actual height of the mine operation area and the dust removal requirements.

[0032] The working principle of the spray mechanism 3 is as follows: the piston rod of the electric telescopic rod 3022 is extended, and then the lifting column 302 is driven to rise through the connecting block 3021, and at the same time the guide rod 304, the threaded rod 303 and the box body 305 are driven to rise, and then the mounting seat 307 and the spraying rod 308 are driven to perform preliminary height adjustment, and then the threaded rod 303 is driven to rotate by the driving motor 306, and then the box body 305 is driven to rise again with the cooperation of the threaded rod 303 and the threaded hole 3023, thereby realizing the secondary height adjustment of the spraying rod 308, and then the solution extracted by the water pump 7 enters the spraying rod 308 through the outlet pipe 701 for salt solution spraying, thereby realizing the treatment of dust.

The salt solution in the salt solution reserve tank 6 is pumped into the spray mechanism 3 by the water pump 7 for spraying. The salt solution will fully contact and mix with the dust generated by mining. Due to the adsorption effect of the salt solution, the dust particles are quickly wrapped and condensed into larger particles. These particles fall onto the extension plate 5 and the reflux trough 4 under the action of gravity, and then flow back to the salt solution reserve tank 6 through the reflux pipe 8. The dust particles flowing back from the salt solution reserve tank 6 can be filtered by the filter 9 to prevent them from entering the water pump 7.

[0037] In summary, with the help of the above-mentioned technical solutions of the present invention, the structure of the present invention is scientific and novel. The dust removal device can effectively remove dust generated during mining operations, reduce the dust concentration in the air, thereby improving the working environment of workers, reducing the risk of workers inhaling harmful dust, and thus protecting the health of workers. By providing an extension plate 5, the water droplets that absorb dust are collected, so that the solution containing dust after spraying can be collected and returned to the salt solution storage tank 6, which not only reduces resource waste and operating costs, but also avoids the secondary dusting of dust on the ground caused by the evaporation of water droplets, effectively improving the mining environment. By providing a spraying mechanism 3, the spraying of salt solution is achieved, and the dust can be absorbed by the sprayed salt solution. Under the drive of the electric telescopic rod 3022 and the drive motor 306, the spraying rod 308 can be driven to perform multi-level height adjustment, and the position of the spraying rod 308 can be flexibly adjusted according to the actual height of the mining operation area and the dust removal requirements.
