Description

[0001] The invention relates to the technical field of mine ventilation and dust reduction equipment, and in particular to an automatic control slide rail device for mine ventilation and dust reduction. Background Art

[0002] During the mining process, tunnels need to be dug inside the mining area so that workers and work equipment can excavate and transport ore. Since the mining working face is a one-way closed area, a circulating airflow cannot be formed naturally inside it. In order to ensure the oxygen content around the working face and the ventilation and dust reduction needs, a ventilation device will be installed at the rear end of the working face to form a gas circulation flow.

[0003] Existing ventilation and dust reduction mostly adopts a structure composed of an atomizing device and a fan.

The stretching cloth 35 is spread on the top surface of the sliding seat 33 and is fixedly connected to the cleaning rod 34. Through the arrangement of the stretching cloth 35 and the storage block 36, it is possible to prevent water from carrying dust into the T-slot on the sliding seat 33, thereby preventing the device from being blocked and difficult to operate.

[0021] Working principle: In this embodiment, the present invention also proposes a method for using a mine ventilation and dust reduction automatic control slide rail device, comprising the following steps: Step 1: First, install the power supply for the device, then add water to the water storage box 17 and install the empty filter cleaning box 23 into the recovery tank 12, and fix the cleaning limit blocks 4 on both sides of the dust reduction box 3, and then start the device. The setting of the upper limit protrusion 14 on the cleaning limit block 4 can better clamp and fix the device on the slide rail 2, reduce the ups and downs of the device, and push away and remove the dust on the slide rail 2, so that the sliding of the device is more stable; Step 2, then start the electric wheel 5, the rubber sleeve on the electric wheel 5 can make the electric wheel 5 close to the slide rail 2, so that the sliding operation of the device is more stable, and dust or water on the slide rail 2 is prevented, which causes the device to slip. At the same time, start the first motor 9, so that the impeller 11 rotates to drive the airflow to accelerate the flow. When the impeller 11 rotates, the atomizer 10 on the fixed frame is turned on to spray the water into the air, thereby completing the dust content in the mine tunnel; Step 3: When the device is in sliding operation, the impeller 11 continuously drives the airflow to pass through the dust removal mechanism in the dust removal box 3. The airflow first carries the dust through the first filter plate 7. The spray plate 38 on the first filter plate 7 sprays and drops water. When the water is sprayed and dropped, it wets the adsorption plate 28, so that the adsorption capacity of the adsorption plate 28 for dust is enhanced, thereby reducing the dust content in the air. The dust adsorbed on the adsorption plate 28 is removed together with the swept cleaning mechanism 21 and the flushed water, so that the dust is driven back to the reflux box 16. The setting of the inclined hole 29 can better prevent the water from sliding and dripping into the first filter plate 7, and through the staggered effect of the opening of the inclined hole 29, the stroke of the airflow passing through the first filter plate 7 is extended, thereby improving the filtering effect of the first filter plate 7; Step 4: At the same time, the cleaning rod 34 on the sweeping cleaning mechanism 21 slides back and forth under the drive of the linear motor, and the brush abuts against the first filter plate 7, and moves to remove the dust on the first filter plate 7. The setting of the stretching cloth 35 and the storage block 36 can prevent the water from carrying dust into the T-shaped groove on the sliding seat 33, thereby preventing the device from being blocked and difficult to operate. Then the airflow passes through the barrier filler 20 of the first filter plate 7 and the second filter plate 18 assembly. The barrier filler 20 is a porous filtering structure, so that the dust is dropped by the spray hole 37 and the water wets the barrier filler 20 to filter the dust by the water adsorption principle; Step five, finally, the airflow is accelerated by the impeller 11 and drives the water mist sprayed by the atomizer 10 to complete dust reduction in a larger range. The dirty water flowing into the reflux box 16 flows into the filter cleaning box 23 through the liquid guide tube 22. The dirty water dropped by the barrier filler 20 directly drips into the filter cleaning box 23. The filter box 24 is set to better filter and block the dust, thereby completing the collection and separation of the dust. The water enters the recovery box 25 after filtration, and is re-sucked and recovered into the water storage box 17 through the suction pump at the end of the reflux pipe 19, thereby completing the recycling of the water, thereby extending the single water filling use time of the device, and the use of the device ends here.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
