Background technique

With the extension of mine mining depth, mine ventilation is facing more and more difficulties. There is a lot of dust in the mine, and the temperature is greatly affected by the external environment. In winter, the temperature under the mine will become very low, which is not only unfavorable for the health of the workers, but also affects the work efficiency of the workers under the mine.

Utility model content

In order to solve the problem that the ambient temperature in mines or tunnels is inconvenient to adjust, the utility model provides a temperature-adjustable ventilation device for mines. Changing the overall ambient temperature in the mine and maintaining a suitable temperature in the mine has brought good news to the workers in the mine.

The technical solution adopted by the utility model to solve its technical problems is: the mine temperature-adjustable ventilation device mainly includes a high-speed spray room and a pool, the high-speed spray room is provided with a water supply pipe for the atomizing nozzle, and a water supply pipe for the atomizing nozzle is provided on the water supply pipe. There is an atomizing nozzle, the middle part of the water supply pipe of the atomizing nozzle is connected to the water inlet pipe of the spray room, and the water inlet pipe of the spray room protrudes from the side of the high-speed spray room, and the air inlet of the air supply tube is equipped with a dust filter net, which can effectively filter the wind. The dust in the air makes the clean air flow into the high-speed spray room. The front part of the high-speed spray room is fixed with a front water shield, and the rear part is fixed with a rear water shield. The purpose is to ensure that the air flow and the atomized water are completely separated. Heat and mass exchange, and at the same time separate the air flow entrained with water droplets; both ends of the high-speed spray chamber are installed on the air supply cylinder of the excavation work face, and the lower part of the high-speed spray chamber is connected to the return pipe of the spray chamber outward, and the return pipe of the spray chamber The front end of the water pipe is connected with the pool, the wall of the pool is provided with a refrigerator and a heater, the lower part of the pool is connected with the outlet pipe of the pool, and the outlet pipe of the pool is provided with a pressurized water pump and a flow regulating valve.

If the temperature in the mine is very high, turn on the refrigerator, let the cooled water flow through the water inlet pipe of the spray chamber into the water supply pipe of the atomizing nozzle, and then spray it into the air supply flow of the air duct through the atomizing nozzle, and the air flow and atomization After heat and mass exchange, the water flows out of the high-speed spray chamber, thereby cooling the environment in the mine or tunnel. The water accumulated in the high-speed spray chamber can be returned to the pool through the return pipe of the spray chamber.

If the temperature in the mine is very low, turn on the heater, and the heated water flows through the water inlet pipe of the spray chamber into the water supply pipe of the atomizing nozzle, and then sprays into the air supply air flow of the air duct through the atomizing nozzle, and the air flow and atomization After the heat and mass exchange, the water flows out of the high-speed spray chamber, thereby realizing the heating of the environment in the mine or tunnel. The water accumulated in the high-speed spray chamber can be returned to the pool through the return pipe of the spray chamber.

The beneficial effect of the utility model is that the temperature-adjustable ventilation device for mines can change the overall ambient temperature in the mines by heating or cooling the air supply flow into the mines, so as to keep a suitable temperature in the mines all the time, and provide ventilation for the mines. The following staff brought the gospel.
