Pure water is produced through the water treatment device, and a pump station water tank is arranged at the crossheading position of the working surface; because the length of the water treatment device is too long, the water treatment device and the pump station water tank are difficult to be installed on a working face crossheading together, the underground roadway and the underground chamber are different in condition, and the distance between the water treatment device and the installation position of the pump station water tank can reach more than thousands of meters. Due to long-distance conveying, impurities such as metal ions (such as metal ions generated by pipelines, flanges, valves and the like) can be mixed in the pure water, so that the resistivity of the pure water is decayed, and the pure water medium entering a water tank of a pump station cannot reach the requirement of a pure water medium hydraulic system of a fully mechanized mining face.

When the resistivity of the pure water treated by the purification device 20 is greater than or equal to the first threshold value and the resistivity of the pure water treated by the purification device 20 is smaller than the second threshold value, it indicates that the purification device 20 is in failure, so the controller 22 controls the alarm device to give an alarm to prompt a worker to overhaul the purification device 20.
Optionally, the alarm device comprises a first alarm module (not shown) and a second alarm module (not shown), and when there is a problem in the pure water tank 12 or the delivery pipe 16 between the pure water tank 12 and the purification device 20, the controller 22 controls the first alarm module to give a first alarm; when the purification apparatus 20 malfunctions, the controller 22 controls the second alarm module to issue a second alarm. Through the arrangement of the first alarm module and the second alarm module, the fault reasons can be rapidly distinguished for workers, and the underground coal mine pure water conveying system 100 can be conveniently and timely overhauled.

The pure water is pumped into the polishing mixed bed for secondary lifting of the water resistivity after passing through the long-distance conveying pipeline 16, and the pure water resistivity is not reduced in the whole conveying process; during the water supply period of the lift pump 18, the resistivity of the pure water entering the polishing mixed bed is detected in real time, and if the water quality is unqualified, the controller 22 immediately controls the alarm device to alarm; the controller 22 can send out a signal to remotely control the start and stop of the lift pump 18 according to a liquid level sensor of the pump station water tank 14; when the liquid level of the pump station water tank 14 reaches the set lower limit, the first liquid level sensor sends a signal, the controller 22 controls the lifting pump 18 to start, pure water is pumped into the long-distance conveying pipeline 16 through the lifting pump 18, then enters the polishing mixed bed to carry out resistivity secondary lifting and then enters the pump station water tank 14 until the water level of the pump station water tank 14 reaches the upper limit, the second liquid level sensor sends a signal, the controller 22 controls the lifting pump 18 to stop, and the process is repeated in cycles.
The utility model provides a colliery is long distance pure water conveying system in pit can keep the pure water resistivity not to reduce in long distance transportation process in the pit, has guaranteed to combine to adopt the high quality supply that working face pure water medium hydraulic system used the pure water, realizes simultaneously that long distance automatic control in the pit supplies the resistivity of cutting off the water and effectively monitor the transport pure water.
Specifically, during the water supply of the lift pump 18, the resistivity of pure water entering the polishing mixed bed is detected in real time, and if the water production is unqualified, the controller 22 immediately alarms and/or controls the lift pump 18 to stop and immediately prompts a worker to detect the reason of the unqualified resistivity.
