[0026] In this embodiment, the filter assembly 11 includes a filter barrel 111. A discharge pipe 112 is fixedly connected to the lower right side of the outer surface of the filter barrel 111. A connecting thread 116 is provided on the upper part of the inner wall of the filter barrel 111. A connecting block 115 is inserted into the inner groove wall of the connecting thread 116.

A support rod 118 is fixedly connected to the middle of the upper end of the support filter plate 117. Three No. 1 filter plates 119 are sleeved on the outer surface of the support rod 118.

[0027] The above scheme involves a fine filtration process for the cooled liquid oxygen using the filter assembly 11. The support filter plate 117 and the three No. 1 filter plates 119 are interlocked with the filter barrel 111. The connecting block 115 and the connecting thread 116 are interlocked to position the connecting cover 113.

[0028] In this embodiment, the adsorption component 9 includes a support frame 91.

A connecting frame 94 is inserted through the upper end of the support frame 91.

These operations complete the assembly of the device, and the connection and disassembly of each component are convenient, facilitating subsequent cleaning and maintenance and improving the flexibility of the device. Liquid oxygen enters the purification device through the oxygen supply pipe 5 and first undergoes primary filtration through the filter cylinder 4. The filter cylinder 4 can intercept large particulate impurities in the liquid oxygen, preventing these impurities from entering the subsequent equipment and causing blockage, ensuring the smooth progress of the entire purification process. The liquid oxygen after primary filtration enters the heater 2, which heats the liquid oxygen to a suitable temperature. Temperature is crucial for the subsequent purification process. During heating, temperature monitoring sensor 3 monitors the temperature inside heater 2 in real time to ensure it remains within a suitable range and prevents abnormal temperatures from affecting the purification effect. The heated liquid oxygen is then transported to the front purification tower 7 via high-pressure pump 6 and pipelines. The three purification towers 7 perform multiple separations on the liquid oxygen, initially removing some impurities and different components. Afterward, the liquid oxygen is transported to adsorption assembly 9 via connecting pipe 8. Several adsorption plates 944 on adsorption assembly 9 sequentially adsorb and filter the liquid oxygen flowing through frame 942, further removing impurities and improving the purity of the liquid oxygen. The adsorbed and filtered liquid oxygen is then transported to cooler 10 via pipelines to reach a suitable temperature. The cooled liquid oxygen is then transported to filter assembly 11, where it is filtered again using support filter plate 117 and three support rods 118 to further remove residual impurities, thereby significantly improving the filtration and adsorption effect of the entire liquid oxygen purification equipment and obtaining high-purity liquid oxygen.
