Description

Technical Field

[0001] The utility model relates to the technical field of coal mine ventilation equipment, in particular to a ventilation and air exchange device for underground coal mine operations. Background Art

[0002] The commonly used ventilation devices for underground coal mine operations are exhaust fans and air duct systems. Exhaust fans extract the dirty air in underground tunnels and then discharge it to the ground, and use the air duct system to transport fresh air to ensure the circulation and renewal of air inside the mine, thereby ensuring the safety of workers and a suitable working environment. The commonly used ventilation devices for underground coal mine operations need to be connected to pipelines when transporting air to the coal mine, but the pipelines are easily damaged and leaked in the coal mine, resulting in insufficient air delivery, which can easily cause insufficient oxygen and cause danger.

[0003] A Chinese patent discloses an underground ventilation device for coal mining (authorization announcement number CN211144551U). The patented technology mainly includes an air inlet pipe, an acid-base neutralization box, a chemical box, a connecting plate and a device body. A first air outlet pipe is arranged at the top of the purification box inside the acid-base neutralization box, and a dust removal mechanism is arranged on one side of the first air outlet pipe. A second primary filter is installed on the inner wall at both ends of the dust removal mechanism, and a second fine filter is installed between the inner walls at both ends of the dust removal mechanism on one side of the second primary filter. A second air outlet pipe is arranged on the other side of the purification box, and a sound-absorbing sponge layer is arranged on the outer walls of the air inlet pipe, the first air outlet pipe and the second air outlet pipe.

[0004] However, there are still some shortcomings in this patent. This patent achieves the filtering of coal slag to avoid polluting the environment above the mine by installing a second primary filter on the inner walls at both ends of the dust removal mechanism, and installing a second fine filter between the inner walls at both ends of the dust removal mechanism on one side of the second primary filter. However, the pipeline is easily damaged by collision and leaks in the coal mine, resulting in insufficient air delivery, which is easy to cause oxygen deficiency and cause danger. Therefore, those skilled in the art provide a ventilation device for underground coal mine operations to solve the problems raised in the above background technology. Utility Model Content

[0023] Specifically, the diameter of the semicircular telescopic sleeve matches the diameter of the conveying pipe, so that the conveying pipe can pass through the semicircular telescopic sleeve and the conveying pipe can be protected.

[0024] 2. Beneficial effects

[0025] Compared with the prior art, the advantages of the present invention are:
