Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction in coal mines, in particular to a combined dust reduction device in coal mines. Background Art

[0002] A large amount of dust is generated during underground coal mining. Miners working in a dusty environment may suffer from safety accidents due to greatly reduced vision, and may also increase the risk of pneumoconiosis. Therefore, high-pressure spraying and other methods are often used to reduce dust. However, in spray dust reduction devices, the position of the nozzles is generally fixed, and dust can only be sprayed in one direction, resulting in a small spray range and poor dust reduction effect.

[0003] The existing published patent number is: CN213450474U. A combined dust reduction device for underground coal mines includes a box body, a mounting frame is fixedly connected to the upper side of the box body, and the side wall of the mounting frame is provided with four openings. A rack is penetrated through the upper side of the box body, and the rack is slidably connected to the box body. A dust reduction mechanism for spraying dust reduction is provided inside the box body. The utility model has a reasonable structural design, which can make the nozzle swing while moving up and down, so that the device can spray dust in different directions at the same time, greatly increasing the dust reduction effect.

[0004] Although the above scheme can make the nozzle swing while moving up and down, so that the device can spray dust in different directions at the same time, greatly increasing the dust reduction effect, but in actual use, the nozzle sprays water to reduce the dust in the air, and the sprayed water finally falls to the ground, causing water waste. In this device, if the water used in dust reduction can be recycled and reused, the waste of water resources can be reduced, thereby indirectly reducing the cost of dust reduction.

Threaded rod 120 is embedded in the second clamping hole 121 to limit the inclined plate 119.

At the same time, the hydraulic cylinder 110 is started by power supply to push the lifting plate 109 to slide inside the slide 112. At this time, the lifting plate 109 can drive the sprinkler 106 to adjust the height, and the sprinkler 106 can reduce dust in higher spaces. The electric push rod 107 pushes the movable plate 108 to rotate in a horizontal semicircle around the lifting plate 109 as the center, so that the sprinkler 106 can adjust the angle when reducing dust, thereby improving the dust reduction efficiency of the sprinkler 106. After the water sprayed by the sprinkler 106 is used to reduce dust, part of the water will reach the surface of the filter plate 114, and the filter plate 114 will filter the dust in the water. The water enters the surface of the slide bar 123 and flows into the interior of the water collecting box 113 through the inclined plate 122 for recovery. To recover the water, pull the inclined plate 119 to slide on the surface of the slide bar 123, and pull the filter plate 115 to slide inside the filter plate 114. At this time, the inclined plate 119 is located directly below the filter plate 115, rotate the threaded rod 117 to embed it into the inside of the clamping hole 116, and rotate the threaded rod 120 to embed it into the inside of the clamping hole 121, so as to limit the inclined plate 119 and the filter plate 115.
