Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1-3, a control system for oxygen saturation in a steel cylinder includes a nitrogen charging device and a vacuum pumping device, the vacuum pumping device includes an air pumping pipeline 10, a vacuum pump 4 and an oil mist filter 3, the vacuum pump 4 is respectively connected with the oil mist filter 3 and the air pumping pipeline 10, the air pumping pipeline 10 is communicated with the steel cylinder 5, the air pumping pipeline 10 is connected with an air storage tank 2, the air pumping pipeline 10 is fixedly provided with a first valve 15 and a first buffer tank 17, the first buffer tank 17 is located between the first valve 15 and the steel cylinder 5, the first buffer tank 17 is provided with a pressure sensor 18, the nitrogen charging device includes a nitrogen pipeline 9, the nitrogen pipeline 9 is connected with pipeline nitrogen outside the system, the nitrogen pipeline 9 is communicated with the steel cylinder 5, the nitrogen pipeline 9 is fixedly provided with a second valve 16 and a second buffer tank 19, the second buffer tank 19 is located between the second valve 16 and the steel cylinder 5, and the second buffer tank 19 is provided with an oxygen sensor 20.
In the above embodiment, the pressure sensor 18 may be directly provided on the steel cylinder 5, and the oxygen sensor 20 may be directly provided on the steel cylinder 5.
The control method of the control system for the oxygen saturation inside the steel cylinder comprises the following steps: firstly, opening the first valve 15, closing the second valve 16, starting the operation of the vacuum pump 4, vacuumizing the steel cylinder 5 through the air exhaust pipeline 10, and exhausting the gas in the steel cylinder 5 after filtering through the oil mist filter 3. After the evacuation was accomplished, vacuum pump 4 stop operation, valve 15 is closed, and steel bottle 5 was in the pressurize state this moment, and pressure sensor 18 measures the gas pressure value in buffer tank 17, because buffer tank 17 and steel bottle 5 intercommunication, measures the gas pressure value in buffer tank 17 this moment and is exactly the steel bottle 5, and buffer tank 17 has the buffering effect simultaneously and can make measured value more accurate, and can protect pressure sensor 18, extension pressure sensor 18's life. When the pressure in the steel cylinder 5 is kept for a certain time, the detected pressure value changes within a qualified range, which indicates that the steel cylinder 5 has good sealing performance and no leakage, and can be used for storing rare earth. If the pressure value detected by the pressure sensor 18 exceeds the qualified range, the alarm lamp gives an alarm to prompt. After the pressure maintaining is finished, if the tightness of the steel cylinder 5 is good, the first valve 15 and the second valve 16 are opened, nitrogen is filled into the steel cylinder 5 through the nitrogen pipeline 9, the original gas in the steel cylinder 5 after the nitrogen is filled begins to be discharged outwards along the air exhaust pipeline 10, and the second valve 16 is closed after the nitrogen filling is finished. After the primary vacuumizing and nitrogen filling operation is finished, the oxygen content in the steel cylinder 5 can be reduced, and because the second buffer tank 19 is communicated with the steel cylinder 5 and the oxygen contents in the two are equal, the oxygen sensor 20 only needs to measure the oxygen content in the second buffer tank 19, and if the measured oxygen content in the steel cylinder 5 does not reach the standard, the vacuumizing and nitrogen filling operation is repeated until the oxygen content reaches the standard.
The protection scope of the present invention includes but is not limited to the above embodiments, the protection scope of the present invention is subject to the claims, and any substitutions, modifications, and improvements that can be easily conceived by those skilled in the art are all within the protection scope of the present invention.
