Description

Technical Field

[0001] This utility model relates to the field of ventilation and dust removal, specifically to a ventilation and dust removal device for underground mining. Background Technology

[0002] Coal mines are areas where people extract coal resources in coal-rich mining areas. During the mining and transportation of coal, a large amount of dust is generated. If the dust is not treated, it will have an adverse effect on the health of workers and seriously endanger their health and safety. Therefore, ventilation and dust removal systems are generally used to clean up the dust inside the coal mine during mining operations.

[0003] For example, the Chinese utility model patent with publication number CN219308303U can clean and filter dust in the air inside a coal mine from multiple angles and directions, avoiding the need for manual adjustment of the direction and angle during use. At the same time, the filter screen can be disassembled and replaced through the dust removal and ventilation components, avoiding the problem of excessive dust accumulation on the filter screen, which would affect the filtration effect.

[0004] However, when using internal water flow to adsorb impurities in the air, the water flow can easily become turbid after a long period of operation, which leads to a decrease in adsorption efficiency and makes it difficult to filter and reset the water flow in time during operation, which is inconvenient. In view of this, we propose an underground mining ventilation and dust removal device. Utility Model Content

[0008] As a preferred technical solution of this application, the upper end of the drive shaft rotates through the interior of the water tank, and the upper end of the drive shaft is fixedly connected to the lower surface of the rotating disk.

[0009] As a preferred technical solution of this application, the separation tank is provided with a drain pipe that extends to the outside of the water tank and is equipped with a valve. An annular partition is fixedly connected to the top wall of the separation tank.

[0010] As a preferred technical solution of this application, a filter plate is fixedly installed on the inner wall of the annular partition, and the end of the return pipe extends into the interior of the annular partition.

[0011] As a preferred technical solution of this application, the end of the first water pipe extends to the left side surface of the partition plate, and the second water pipe extends into the interior of the separation tank.

[0012] As a preferred technical solution of this application, the second water pipe is arranged in a spiral shape, and two vent pipes are provided on the upper surface of the water tank, with the lower ends of both vent pipes extending into the interior of the water tank.

With the cooperation of the separation tank 8 and the internal solid-liquid separation component, impurities in the water flow can be separated after the water flow becomes turbid, thereby achieving water filtration and purification, realizing the internal water flow recycling, and solving the problem of poor adsorption effect caused by water turbidity.

[0031] Example 2

[0032] The underground mining ventilation and dust removal device provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the solid-liquid separation assembly includes a rotating disk 13, which is rotatably connected to the bottom wall of the separation tank 8. A blade 14 is fixedly connected to the upper surface of the rotating disk 13. The rotating disk 13, in conjunction with the blade 14, drives the liquid inside the separation tank 8 to rotate and separate. A motor 15 is fixedly connected to the lower surface of the bottom plate 1. A drive shaft 16 is fixedly connected to the output end of the motor 15. The upper end of the drive shaft 16 rotates through the interior of the water tank 2. The upper end of the drive shaft 16 is fixedly connected to the lower surface of the rotating disk 13. A drain pipe 17 is provided on the separation tank 8. Impurities and water inside the separation tank 8 are discharged through the drain pipe 17. The drain pipe 17 extends to the outside of the water tank 2. A valve 18 is provided on the drain pipe 17. The valve 18 controls the opening and closing of the drain pipe 17.

[0033] An annular baffle 19 is fixedly connected to the top wall of the separation tank 8, separating impurities in the outer area. A filter plate 20 is fixedly installed on the inner wall of the annular baffle 19, filtering impurities remaining in the water flow. The end of the return pipe 9 extends into the interior of the annular baffle 19. The end of the first water pipe 11 extends into the left side surface of the partition plate 6. The second water pipe 12 extends into the interior of the separation tank 8 and is arranged in a spiral shape. Two exhaust pipes 21 are provided on the upper surface of the water tank 2, through which purified air is discharged. Both exhaust pipes 21 extend to the interior of the water tank 2 at their lower ends. The outer surface of the transmission pipe 5 has an air outlet 22 extending into it. Air is evenly delivered to the water through the air outlet 22. A baffle cylinder 23 is slidably fitted on the outer surface of the transmission pipe 5. An air bag 24 is fixedly fitted on the outer surface of the baffle cylinder 23. With the help of the air bag 24 and the baffle cylinder 23, the air outlet 22 above the water surface can be automatically blocked to prevent air from escaping directly. At the same time, the circumferentially opened air outlet 22 can make the air more evenly distributed when entering the water.

[0034] The dust collection component includes a fan and a filter component. The filter component specifically consists of a preliminary filter and corresponding installation components. The fan is connected to the dust collection pipe 4 and the transmission pipe 5 to draw outside air into the water tank 2. The dust collection box 3 also has a drive component for rotating the dust collection pipe 4. The drive component consists of a DC motor, a rotating shaft, a rotating rod, a rotating disk, a toggle lever, and a concave ring. All of the above are existing technologies. For details, please refer to the dust removal and ventilation component in patent publication number CN219308303U. Since it is not the main direction of improvement, it will not be described in detail here.

[0035] The usage process of the underground mining ventilation and dust removal device provided by this utility model is as follows:

[0036] When removing dust from the well air, the suction components inside the suction box 3, in conjunction with the suction pipe 4, guide the air into the transmission pipe 5, and then inject the air into the water tank 2 through the transmission pipe 5. The air is then discharged through the vent 22. During discharge, the airbag 24 causes the baffle cylinder 23 to float on the water surface, thereby sealing the vent 22 above the water surface and preventing the air from being discharged directly without being adsorbed by the water flow. After the air is adsorbed by the water flow, it is discharged through the exhaust pipe 21. When filtering the water flow, the pump body 10, in conjunction with the first water pipe 11 and the second water pipe 12, can transport the turbid water inside the water tank 2. The water flows into the separation tank 8, and the spiral arrangement of the second water pipe 12 provides initial rotational power upon entry. Simultaneously, the motor 15, in conjunction with the drive shaft 16, drives the rotating disk 13 to rotate. The rotating disk 13, in conjunction with the blades 14, rotates the water inside the separation tank 8. Centrifugal force throws impurities in the water onto the side wall of the separation tank 8. As the water level gradually rises, the water gradually enters the annular baffle 19 and is filtered by the filter plate 20. After the water level continues to rise, it passes through the return pipe 9, and the filtered water flows back to the left side of the partition plate 6 through the return pipe 9 to achieve circulation.
