The left side of the air intake column 6 is fixedly connected with a fixed column 8, which is convenient for driving the air intake column 6 to rotate. The right side of the threaded column 7 is fixedly connected to the left side of the connecting column 10, and then drives the connecting column 10 to rotate. The left side of the rotating assembly is fixedly connected with a gripping rod 9, and the left side of the fixed column 8 is fixedly connected to the right side of the gripping rod 9. The fixed column 8 is driven to rotate by holding the gripping rod 9. The right side of the rotating assembly is fixedly connected with the connecting column 10. A reset assembly is arranged at the right end of the connecting column 10. The reset assembly includes a rubber plate 11, which is used to tightly fit the perfusion pipe and the connecting column 10 together.

[0028] The right side of the connecting column 10 is fixedly connected to the left side of the rubber plate 11. The connecting column 10 slides inside the rubber plate 11 to generate friction and compress the middle part of the rubber plate 11, so that it can fit more closely with the connecting column 10. The outside of the rubber plate 11 is slidably connected to the inner wall of the sleeve 14. The rubber plate 11 can slide horizontally due to the restriction of the sleeve 14.

[0030] Reference Figure 1 , Figure 4 and Figure 5 A circular hole 19 is provided at the top of the storage tank 2, and a protective layer 23 is fixedly connected to the inner wall of the support frame 1. The material of the protective layer 23 is nickel-plated metal, which is used to protect the entire device and reduce external impact. The inner wall of the protective layer 23 is fixedly connected to a partition layer 22. The material of the partition layer 22 is glass fiber, which is used to isolate the internal temperature from the external temperature. The inner wall of the partition layer 22 is fixedly connected to an insulation layer 21. The material of the insulation layer 21 is a calcium silicate board, which is used to keep the internal tetrahydrofuran temperature warm. The inner wall of the insulation layer 21 is fixedly connected to an inner liner layer 20. The material of the inner liner layer 20 is mineral fiber, which has an anti-corrosion function, avoids erosion to the inside of the device, and extends its service life.

[0031] Working principle: When filling tetrahydrofuran, by holding the handle 9 and applying a rotational force, the fixed column 8 is driven to rotate, and then the threaded column 7 is driven to rotate at the left end of the air intake column 6. At this time, the threaded column 7 will drive the connecting column 10 to rotate inside the air intake column 6 and at the same time rotate away from the inside of the rubber plate 11. On the contrary, the connecting column 10 can fit inside the rubber plate 11, so that the device can be sealed during storage to prevent gas from being embedded in the device and causing tetrahydrofuran to volatilize. After taking out the connecting column 10, the tetrahydrofuran pipeline is inserted into the inner wall of the air intake column 6 and passes through the rubber plate 11. The shaping of the rubber plate 11 generates friction with the connecting column 10, so that after the pipeline passes through the rubber plate 11, it engages with the hole inside the fixed plate 13, and the rubber plate 11 squeezes the spring 12 due to the friction, so that the spring 12 can store elastic potential energy. , and then give the rubber sheet 11 a force in the opposite direction, so that the rubber sheet 11 can fit tightly to the outside of the pipeline, playing the role of injection sealing, and the pressure generated by the injection of tetrahydrofuran will push the fixed ball 17 to slide on the outside of the air inlet column 6, and at the same time, the spring 16 is already in a stretched state, so that when in use, the spring 16 can pull the fixed ball 17 to contact the rubber sheet 15 through elastic force, and the rubber sheet 15 is shaped so that the rubber sheet 15 can be tightly lifted with the fixed ball 17 to further play a secret role, and the pressure of tetrahydrofuran will push the fixed ball 17 to slide. When the fixed ball 17 slides to the inner wall of the right end of the air inlet column 6, there will be a gap between the inside of the air inlet column 6 and the fixed ball 17, so that the tetrahydrofuran can flow to the inside of the connecting column 5, and finally stored in the inside of the storage tank 2, and then the device is sealed as a whole through the valve 18;

[0032] The inner liner layer 20 and the thermal insulation layer 21 are fixedly connected by hot-melt method, and the mineral fiber is heated and shaped at a certain temperature to form the inner liner layer 20, so that it has good corrosion resistance, which can protect the metal surface of the container or pipeline from being corroded by corrosive substances and extend the service life of the equipment. It is combined with the calcium silicate board by heating and extrusion to make it heat-insulating and adapt to high-temperature environment. The protective layer 23 is used to prevent deformation due to external devices, and the isolation layer 22 is used to isolate the external temperature from the internal temperature.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
