Description

Technical Field

[0001] The utility model belongs to the technical field of mine fans, in particular to a fan for safety in non-coal mines. Background Art

[0002] Non-coal mine fans are important equipment for non-coal mine ventilation, and they play a vital role in mine safety production; non-coal mine fans are ventilation equipment specially designed for various non-coal mines such as metallurgy, nonferrous metals, gold, chemicals, building materials and nuclear industries. They can be used as main fans or auxiliary fans, and can be installed on the surface or underground. They are suitable for the joint operation of multiple fans, and are ideal station fans for each level of the multi-fan series-parallel multi-stage station ventilation system. In addition, non-coal mine fans are also suitable for ventilation and air exchange in large workshops, tunnels, civil air defense projects and other occasions;

[0003] Exhaust fans in non-coal mining environments have a lot of dust particles. When discharged through the fan, a lot of dust will adhere to the fan blades and the inside of the fan, causing the fan's performance to drop significantly after a period of use, reducing the fan's working efficiency and failing to meet ventilation requirements, affecting the use effect.

[0004] In comparison, a Chinese patent with authorization announcement number CN218564020U discloses a new type of ventilation fan for safety in non-coal mines, including a bellows shell and a cleaning component. The cleaning component is arranged on the bellows shell, and the cleaning component includes a support cover and a brush. A roller is arranged in the support cover, and a running groove is provided on the roller. A motor is arranged in the support cover, and gears are arranged on one end of the roller and the output shaft of the motor, and the two sets of gears are meshed. A travel groove is provided on the support cover, and a movable shaft is provided in the travel groove. One end of the movable shaft is arranged in the running groove, and a mounting plate is provided at the other end of the movable shaft. A T-slot is provided in the mounting plate, and a brush is arranged in the T-slot. Two sets of dustproof plates are arranged in the bellows shell, and the brush is in contact with one set of dustproof plates. A fan is arranged in the bellows shell, and the fan is located between the two sets of dustproof plates.

[0005] The above patent uses two sets of dust-proof plates to block the dust in the air. Although the dust attached to the fan blades is reduced, the fan is located inside the fan, which is not conducive to maintenance. Therefore, a new device needs to be designed. Utility Model Content
