Abstract
The invention relates to a negative pressure water tank based automatic drainage device for mining and a drainage method thereof. The drainage device comprises a negative pressure water tank and a water pump; the negative pressure water tank is communicated with the water pump through water outlet pipelines; the upper part of the negative pressure water tank is provided with an air inlet and a water injection hole, and the water injection hole is connected with an electric water injection valve; a ball float type liquid level sensor is arranged in the negative pressure water tank. When the water level of a water sump reaches the maximum limit, according to the feedback information of the ball float type liquid level sensor, a controller is allowed to close the electric water injection valve and an air inlet valve and start the water pump. As the water level drops, negative pressure forms in the upper part of the negative pressure water tank, therefore, the water in the water sump is sucked into the negative pressure water tank and discharged through the water pump. After the drainage process, the air inlet valve is opened first, and then the water pump is gradually shut off. By using the ball float type liquid level sensor, the liquid level in the negative pressure water tank is more accurately controlled, the time to open or close each valve and to start or shut off the water pump are determined respectively, pressure fluctuation of the pipelines in the entire device is reduced, the impact on the water pump is thus reduced, and safe and stable operation of the entire device is ensured.
