Description

Technical Field

[0001] The utility model belongs to the field of mine ventilation, and in particular relates to mine ventilation equipment. Background Art

[0002] The function of mine ventilation equipment is to deliver fresh air to the mine, dilute and discharge toxic and harmful gases, and adjust the required air volume, temperature and humidity underground to improve working conditions and ensure safe production. However, 1. The direct discharge of harmful gases and dust from inside the mine can easily cause damage to the environment. It is usually necessary to add a purification element at the end of the equipment. The filter plates of the purification elements of existing mine ventilation equipment are not easy to disassemble and replace, and during the replacement process, operators are prone to inhaling harmful gases, which can cause harm to their health. 2. Manual replacement of the filter plates consumes manpower, and the replacement of the filter plates is not timely, resulting in slow discharge of toxic gases and inability to effectively discharge toxic gases in the well. This in turn causes the toxic gas content inside the mine to exceed the standard, affecting the health of workers, and the excessive concentration of some gases can easily cause explosions, posing safety risks.

[0003] Therefore, a mine ventilation device is proposed to solve the above-mentioned drawbacks. Utility Model Content
