[0014] An in-situ leaching oxygen filling gas-liquid separation device, which comprises ① gas inlet pipe, ② gas outlet pipe, ③ liquid level switch, ④ liquid storage tank, ⑤ pressure relief valve, and ⑥ device support. Oxygen enters through the gas inlet pipe and is discharged by the gas outlet pipe. The liquid in the above-mentioned two pipelines will fall into the liquid storage tank due to gravity. When the liquid reaches the specified liquid level, the liquid level switch drives the pressure relief valve to open. Since the internal pressure of the device is greater than the external pressure, the liquid will automatically discharge from the storage tank. When the liquid level drops, the liquid level switch resets the pressure valve to close ⑤, and continues to collect liquid. Details are shown in the following figure. Figure 1 .

[0015] Oxygen enters through the gas inlet pipe ① and is discharged by the gas outlet pipe ②. The liquid in the above-mentioned two pipelines will fall into the liquid storage tank ④ due to gravity. When the liquid reaches the specified liquid level, the liquid level switch ③ drives the pressure relief valve to open. Since the internal pressure of the device is greater than the external pressure, the liquid will automatically discharge from the storage tank. When the liquid level drops, the liquid level switch resets the pressure valve to close ⑤, and continues to collect liquid.
