[0024] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Embodiment 1
[0026] like Figure 1 As shown, this embodiment provides a mine dust isolation device, including a dust isolation mechanism 1 and a wind protection mechanism 2.
[0027] like Figure 1 As shown, the dust isolation mechanism 1 includes a first vertical plate 11, a first horizontal plate 12, and a second horizontal plate 13. The first horizontal plate 12 and the second horizontal plate 13 are fixed at the front and rear ends of the first vertical plate 11 in opposite directions. The angle between the first horizontal plate 12 and the first vertical plate 11 is between 50° and 150°, and the angle between the second horizontal plate 13 and the first vertical plate 11 is between 50° and 150°. In this embodiment, the angles between the first horizontal plate 12, the second horizontal plate 13 and the first vertical plate 11 are all 90°. The first horizontal plate 12 is connected to the first safety door 121, and the second horizontal plate 13 is connected to the second safety door 131. The first safety door 121 and the second safety door 131 can be closed and opened; the dust isolation mechanism 1 is installed between the coal leakage eye and the air intake lane. The wind speed in the coal chute area is reduced from a high wind speed to a low wind speed area. The dust below the coal chute no longer enters the air intake lane, which effectively realizes dust isolation and solves the dust problem of the coal leakage eye.
[0028] like Figure 2 , Figure 3 As shown, the windproof mechanism 2 includes a base 21 and a coal outlet 22. The base 21 is hollowed out from top to bottom. The base 21 is provided with a coal outlet 22 at the bottom. The top of the base 21 is fixed at the coal leakage hole. In this embodiment, the base 21 is cylindrical and the coal outlet 22 is arched. Figure 2 As shown, the coal outlet 22 is arranged away from the wind direction, which effectively reduces the area of the coal directly blown by the tunnel wind flow (low wind speed area) during the falling process, and further reduces the flying of dust.
[0029] When using, Figure 1 The belt conveyor (not shown) in the tunnel above the example tunnel conveys the coal to the coal leakage hole, and the coal falls from the coal outlet 22 on the base 21 to the Figure 1On the belt conveyor in the example; because of the right-side air inlet tunnel, the coal leakage eye is in the high wind speed tunnel section of the total air inlet tunnel, and the "Z"-shaped dust isolation mechanism 1 is fixed between the coal leakage eye and the air inlet tunnel. The wind speed in the coal chute area is reduced from a high wind speed to a low wind speed area, and the dust under the coal chute no longer enters the air inlet tunnel, effectively realizing dust isolation and solving the dust problem of the coal leakage eye.
