Mining air-compression automatic water discharging device

Abstract

The invention discloses a mining air-compression automatic water discharging device. The mining air-compression automatic water discharging device comprises a water tank and a negative pressure pipeline, an upper end exhaust pipe is in communication with the position, close to the top, of the right side of the water tank, a water inlet pipe is in communication with the position, close to the bottom, of the right side of the water tank, a water outlet pipe is in communication with the position, close to the bottom, the left side of the water tank, directional valves are arranged in the upper end exhaust pipe, the water inlet pipe and the water outlet pipe, the water tank is arranged below the negative pressure pipeline, the top of the negative pressure pipeline is in communication with theupper end exhaust pipe through a connecting pipe, and the top of the negative pressure pipeline is in communication with the water inlet pipe through the connecting pipe. According to the mining air-compression automatic water discharging device, water flow in the negative pressure pipeline continuously flows into the water tank, so that a buoyancy ball pushes a sealing valve open, the negative pressure state in the water tank is broken, and automatic water discharging is completed.

Description

technical field [0001] The invention relates to the field of comprehensive prevention and application of gas drainage in coal mines, in particular to an air-compressed automatic water release device for mines. Background technique [0002] In the field of comprehensive prevention and application of coal mine gas drainage, gas and water will mix in the negative pressure pipeline, and a large amount of water will accumulate in the low-lying position of the negative pressure pipeline to block the pipeline, resulting in the failure of gas drainage. The traditional method is to play the function of automatically draining water by a water drainer. But this drain device is complex in structure, easy to block, cost is high, and efficient is low, still needs manual operation to release water (does not play real automatic water discharge function) etc. If the water is not released in time, the efficiency of gas drainage will be reduced, which will affect the comprehensive prevention ...

AI Technical Summary

Problems solved by technology

However, the drainer has a complex structure, is easy to block, has high cost, and low efficiency, and still needs manual operation to release water (does not have a real automatic water release function), etc.

If the water is not released in time, the efficiency of gas drainage will be reduced, which will affect the comprehensive prevention and application of coal mine gas, and bring huge hidden dangers to coal mine safety.
