[0004] In daily use, it has been found that coal mine ventilation fans are specifically designed for ventilation in underground coal mines. They are mainly used to provide fresh air and remove harmful gases to ensure a safe and comfortable working environment in coal mines. However, dust is present during underground operations, which can threaten the health and safety of miners. Prolonged exposure to dust can cause respiratory diseases. Miners usually use dust removal equipment to directly capture and remove dust. However, dust removal equipment has certain drawbacks. It requires regular inspection, cleaning, and maintenance, resulting in high maintenance costs. In addition, dust removal equipment is usually large and occupies a certain amount of space, which is not suitable for some compact mine structures, affecting the working space and safety passages. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing dust removal equipment, such as the need for regular inspection, cleaning, and maintenance, resulting in high maintenance costs, and the large size of the equipment, which takes up considerable space. This makes it unsuitable for some compact mine structures and can affect working space and safety passages. Therefore, this utility model proposes a ventilation fan with dust reduction effect.

Furthermore, dust removal equipment is usually large and occupies considerable space, making it unsuitable for compact mine structures and impacting working space and safety passages. In such cases, a dust suppression mechanism can be used in conjunction with the ventilation fan body. This allows the ventilation fan body to suppress dust even in compact mine structures, improving miners' health and safety.

For respiratory diseases, miners typically use dust removal equipment to directly capture and remove dust. However, dust removal equipment has certain drawbacks. It requires regular inspection, cleaning, and maintenance, resulting in high maintenance costs. Furthermore, dust removal equipment is usually large and occupies considerable space, making it unsuitable for some compact mine structures, as it can affect working space and safety passages. In such cases, a dust suppression mechanism 2 can be used in conjunction with the ventilation fan body 4. This allows the ventilation fan body 4 to suppress dust even in compact mine structures, improving miners' health and safety.

[0035] Detailed Instructions for Use: Fill the water storage tank 207 with water and place it in the placement groove 219 on the base plate 208. Connect the water storage tank 207 to the sealing cap 206. Rotate the rotating cylinder 210 within the connecting cylinder 211. Use different sized guide pipes 212 depending on the application. Adjust the guide pipe 212 of the required size on the rotating cylinder 210 to the corresponding position on the outlet pipe 204. The size of the guide pipe 212 can be adjusted according to the difficulty of dust removal inside the well. Then start the ventilator body 4 and the water pump 203. The water pump 203 will move and draw water from the bucket through the water inlet pipe 205 and the water outlet pipe 204. At this time, the water in the water outlet pipe 204 will flow into the guide pipe 212, and the water droplets will fall on the fan blades of the ventilator body 4 through the guide pipe 212. The fan blades hit the water droplets, which will atomize the water droplets and allow them to come into contact with dust particles in the air through the ventilator body 4. The dust will be attached to the water droplets, thereby reducing the floating dust in the air.

[0036] Place the water storage tank 207 on the base plate 208. Then, rotate the rotating rod 32. The movement of the rotating rod 32 will drive the clamping plate 34 to move. The movement of the clamping plate 34 will move towards the water storage tank 207 under the action of the guide rod 33. Thus, by rotating the rod 32, the clamping plate 34 can clamp the water storage tank 207.
