The heating elements 24 can cooperate with catalysts to convert oxygen into other compounds, such as water. This method requires a higher reaction temperature and a suitable catalyst, but can improve the extraction efficiency.

[0024] The fixed plate 25 is provided with a drain port 26, the bottom inner wall of the deoxygenation device body 1 is fixedly connected with a water pump 35, the bottom of the deoxygenation device body 1 is fixedly connected with a liquid outlet pipe 18, the outer side of the liquid outlet pipe 18 is provided with a sealing cover, the bottom of the liquid outlet pipe 18 is provided with a filter frame 19, the filter frame 19 is connected to the bottom of the liquid outlet pipe 18 by a plurality of screws 20, the filter frame 19 is provided with a filter screen 21, the top of the bottom plate 2 is placed with a liquid tank 14, the liquid tank 14 is located directly below the liquid outlet pipe 18, and the device is used so that the sealing cover is always inserted and installed below the liquid outlet pipe 18 When the extraction efficiency is improved by the heating element 24 and the catalyst, the remaining water in the device will flow to the bottom of the fixed plate 25 through the drain port 26.

During long-term use, the device may form some lumps after extraction, which may carry harmful substances. The filter screen 21 can isolate them. When personnel need to clean the lumps, they can take off the filter screen 21 by loosening the screws 20 for protection, which is convenient for subsequent processing.

[0025] The working principle of the present invention is as follows:

[0026] When personnel need to maintain the device and need to open the sealing door 10, the driving end of the electric telescopic rod 11 is passed through the opening 22 and contacts the bottom of the sealing door 10, and the sealing door 10 is pushed to move vertically upward along the limit rod 8. When the convex plate 27 contacts the push block 34, the telescopic rod 32 will move into the fixed cylinder 31, and the spring 33 will be compressed. When the push block 34 contacts the convex point of the convex plate 27, the card hole is just separated from the card rod 29, and then the spring 33 will be stretched, and the push block 34 will push the sealing door 10 to open through the convex block 27. At this time, the fixing frame 6 will move forward a distance. When the personnel need to seal again, they only need to push the sealing door 10 so that the card hole is located just above the card rod 29 and snap it in, thereby speeding up the maintenance speed of the personnel and reducing the installation time after maintenance. After the personnel closes the sealing door 10, the air and other gases that enter the deoxygenation device body 1 during maintenance are discharged into the gas storage box 16 through the true gas pump 15, thereby ensuring the vacuum effect in the device.

[0027] The heating element 24 can cooperate with the catalyst to convert oxygen into other compounds, such as water. This method requires a higher reaction temperature and a suitable catalyst, but can improve the extraction efficiency. When the extraction efficiency is improved by the heating element 24 and the catalyst, the remaining water flow in the device will flow to the bottom of the fixed plate 25 through the drain port 26. At this time, the sealing cover is opened and the water pump 35 is started to allow the remaining water flow to flow into the liquid tank 14 through the liquid outlet pipe 18. During long-term use, the device may form some extracted blocks, which may carry harmful substances. The filter 21 can isolate them. When personnel need to clean the blocks, they can take off the filter 21 by loosening the screws 20 to facilitate subsequent processing.
