Description

Technical Field

[0001] The utility model relates to the technical field of air collectors, in particular to an efficient air collector for mine fans. Background Technique

[0002] The air collector for mine fans is a key component in the mine ventilation system. Its main function is to distribute the air flow inhaled by the main ventilation fan to different air intake roadways, so as to adjust and ensure the ventilation of the underground working face. During the underground coal mining operation, the main ventilation fan inhales a large amount of air through the wellhead to form a strong air flow. These air flows are transported to each working area through the underground ventilation pipes. The air collector is responsible for evenly distributing this air flow to each air intake roadway to ensure that each working area can obtain sufficient and uniform air volume.

[0003] The existing air collectors for mine fans are usually fixedly connected to the fans and difficult to adjust in length, resulting in too large a gap between the air collector for mine fans and the impeller, which leads to low working efficiency of the fan. At the same time, due to the different internal environments of the mine tunnels, since most of the existing air collectors for mine fans have a fixed internal ventilation volume, it is difficult for the air collector to change the internal ventilation volume, resulting in the difficulty for the fan to change the ventilation efficiency according to the needs of the mine tunnel environment.
