Description

Technical Field

[0001] This utility model relates to the field of mine ventilation technology, specifically to an underground ventilation device for metal mines. Background Technology

[0002] Ventilation systems in metal mines introduce fresh air into the mine to increase oxygen concentration, thereby diluting and removing toxic and harmful gases and dust from the mine.

[0003] In the prior art, Chinese utility model patent with publication number CN210660163U discloses a ventilation device for underground metal mines. In this patent, water is converted into water mist through a spray device. The fan blades are designed to allow the exhaust gas to come into contact with the water mist. The water mist fully combines with the dust in the exhaust gas. After the water mist accumulates a large amount of dust, it falls downward into the dust collection box. The demisting plate can prevent the water mist containing a small amount of metal dust from being directly discharged to the outside, thus avoiding pollution of the environment by metal dust.

[0004] However, the water used in the spraying process of the above-mentioned spraying device cannot be recycled, which reduces the utilization rate of water resources, and metal dust is inconvenient to collect in water, which will cause waste of resources. Therefore, it does not meet the existing needs. In response, we propose a ventilation device for underground metal mines. Utility Model Content

[0005] The purpose of this utility model is to provide a ventilation device for underground metal mines, in order to solve the problems mentioned in the background art, such as the inability to recycle the water used in the spraying process of the above-mentioned spraying device, which reduces the utilization rate of water resources, and the inconvenience of collecting metal dust in water, which will cause resource waste.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model is equipped with a circulation pipe, a water pump, an electric push rod, a retractable hose, and a limiting ring. By controlling the switch of the water pump, the atomizing nozzle can spray water to mist the exhaust gas. The dust in the exhaust gas combines with the water mist and falls downward due to gravity.

Water without metal dust can be pumped through the circulation pipe and then sprayed through the atomizing nozzle. In addition, a disassembly mechanism is provided to remove the lower shell from the bottom of the upper shell to collect the metal dust adsorbed on the electromagnetic plate. This utility model can recycle water and collect metal dust, avoiding resource waste.

[0014] 2. This utility model, by incorporating a filter device, can prevent some dust that is not sprayed from leaking into the outside through the air outlet pipe. Furthermore, by incorporating a sliding disassembly mechanism, the filter device can be disassembled and installed, facilitating the cleaning of the filter screen and thus ensuring the subsequent ventilation effect.
