Description

Technical Field

[0001] The utility model relates to the technical field of air supply equipment, in particular to underground high-pressure air supply equipment. Background Art

[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly peel off the surface soil layer to mine coal. This is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN214787500U discloses an air supply device for underground excavation in coal mines.

The utility model injects water into the interior of the box body through a water injection port, and through the setting of the partition, the water source is guided into the interior of the dripping head through the through groove, and the water source is drip-irrigated through the dripping head, and the fan is started through the PLC controller. The air is filtered and transported to the water pipe through the dust cover, and the water droplets are blown into water mist through the water pipe, which solves the problem that ventilation is an indispensable link in the mining process of existing coal mines. At present, the ventilation device does not have the function of humidifying air during operation, resulting in wind carrying dust into the interior of the coal mine, which brings unhealthy problems to people's bodies.

However, the sealing effect of the connection between the air supply pipe and the air supply structure is not good, and air leakage is prone to occur, which reduces the practicality of the air supply equipment structure and affects the normal work of the coal mine underground.
