Both ends of the sliding column 2 10 are fixedly connected to the connecting block 9, and the rotation of the sector gear 1 5 and the sector gear 2 6 drives the two groups of connecting rods 7 to rotate, and the rotation of the two groups of connecting rods 7 drives the two groups of sliding rods 1 8 to move back and forth, and the two groups of sliding rods 1 8 drive the two groups of fixed slot blocks 12 to slide back and forth, so that the two groups of fixed slot blocks 12 can clamp or release the palladium membrane tube 13. Therefore, through such a setting, the palladium membrane tube 13 can be quickly disassembled and installed on the storage box 1, making it easier for the staff to disassemble and install the palladium membrane tube 13, and it can also be convenient for people to disassemble the palladium membrane tube 13 for cleaning, thereby increasing the service life of the palladium membrane tube 13.

[0028] A palladium membrane tube 13 is slidably connected to the storage box 1, one end of the palladium membrane tube 13 is fixedly connected to a connecting head tube 14, a spring 15 is fixedly connected to the side of the connecting head tube 14 away from the palladium membrane tube 13, a fixed arc plate 16 is fixedly connected to the side of the spring 15 away from the connecting head tube 14, a palladium membrane plate 17 is fixedly connected to the end of the palladium membrane tube 13 away from the connecting head tube 14, an outlet pipe 19 is fixedly connected to the storage box 1, and an exhaust valve is fixedly connected to the end of the outlet pipe 19 away from the storage box 1 20.

[0029] Working principle: first, insert the palladium membrane tube 13 into the storage box 1, and then start the motor 3. The output end of the motor 3 drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the fan gear 15 to rotate. The rotation of the fan gear 15 drives the fan gear 2 6 to rotate. The rotation of the fan gear 15 and the fan gear 2 6 drives the two sets of connecting rods 7 to rotate inward. The two sets of connecting rods 7 drive the two sets of sliding rods 18 to slide inward. The two sets of sliding rods 18 drive the two sets of fixed slot blocks 12 to clamp and fix the palladium membrane tube 13. Then the hydrogen connecting pipe can be connected to the connecting head pipe 14. Then the spring 15 is subjected to the upward extrusion force, and the outward elastic force drives the fixed arc plate 16 to move downward to fix the hydrogen connecting pipe. Then, hydrogen can be injected into the palladium membrane tube 13 through the hydrogen connecting pipe. When the hydrogen passes through the palladium membrane tube 13, the palladium membrane tube 13 can selectively allow hydrogen to pass through while preventing other impurity gases. Specifically, when the hydrogen contacts the palladium membrane tube 13 At the same time, due to the special adsorption performance of palladium to hydrogen, hydrogen is adsorbed on the surface of the palladium membrane tube 13 and further reacts, thereby improving the purity of the hydrogen. When the hydrogen is purified, the DN40 heating tube 18 can be started, and the DN40 heating tube 18 heats the storage box 1. Under the heating condition, the hydrogen adsorbed on the surface of the palladium membrane tube 13 is more easily desorbed, so that more hydrogen can be purified by the palladium membrane. When the palladium membrane tube 13 needs to be cleaned, the motor 3 can be started again to make the rotating shaft 14 on the motor 3 drive the fan gear 15 and the fan gear 26 to reverse, so that the two sets of slide bars 18 can drive the two sets of fixed slot blocks 12 to move outward, so that the palladium membrane tube 13 can be removed from the storage box 1, thereby facilitating the cleaning of the palladium membrane tube 13.
