Description

Technical Field

[0001] This utility model belongs to the field of mine ventilation and dust suppression technology, specifically a mine ventilation and dust suppression device. Background Technology

[0002] Mines are the main sites for mining operations, providing essential raw materials for many industrial sectors. When mining operations are carried out in the mine shafts, the air is not circulated, and a large amount of dust is generated when mining ore. This not only reduces the air quality of the work area and its surrounding environment, endangering the health and safety of workers, but may also damage machinery and equipment and cause various accidents.

[0003] Dust suppression is often carried out by spraying water. Dust floats on water droplets and falls, creating a dust suppression effect. However, water spraying for dust suppression consumes a lot of water resources. Water is relatively scarce in mines, making it inconvenient to frequently replenish the water for dust suppression. Moreover, the amount of dust is not reduced during the water spraying process. After the water evaporates, the dust particles become dry again and are easily carried away by the wind. Utility Model Content

The other end of the exhaust pipe passes through the top plate of the water storage tank, extending below the water surface. The dust extraction fan draws in moisture-laden dust from the outside environment and sends it into the water in the storage tank.

[0007] Furthermore, a water pump is provided above the support base, and the water pump has a suction pipe at its inlet end that is connected to the lower end of the water storage tank, and a drain pipe at its outlet end that is connected to the annular pipe.
