[0019] Fixed base plate 1: As the basic support component of the entire device, it is used to install and fix the deoxygenation pretreatment component 2 and the support frame 5, providing a stable installation platform for the various structures of the device; Deoxygenation pretreatment component 2: used to perform preliminary deoxygenation pretreatment on the gas entering the device. The treated gas is transported to the filter box 3 through a pipeline. It is the first treatment step in the gas purification process. Filter box 3: As the core chamber for gas filtration and purification, it is equipped with components such as filter screen 11 and molecular sieve 14. It also has a sliding groove 20 for the replacement rack 9 to slide. One side is connected to the deoxygenation pretreatment component 2 through a pipe, and the other side is fixedly connected to the exhaust pipe for discharging pure gas. It is also used to install the top cover 4, electric telescopic rod 6, control panel 7 and other structures. Top cover 4: Installed on top of filter box 3 by bolts, used to seal the top of filter box 3, and facilitates subsequent opening for maintenance or repair of internal components of filter box 3; Support frame 5: It is installed on the top of the fixed base plate 1 by bolts, and the top is fixedly connected to the filter box 3. It is used to support the filter box 3 and keep the filter box 3 at a stable installation height and position. Electric telescopic rod 6: It is fixedly installed on the side of the filter box 3 near the control panel 7. The telescopic end can slide into the inside of the filter box 3 and be fixedly connected to the scraper 12. When it is necessary to clean the filter screen 11, it is controlled by the control panel 7 and drives the scraper 12 to move on the surface of the filter screen 11 through the telescopic end. Control panel 7: Fixedly installed on the side of filter box 3 near electric telescopic rod 6, used to control the working status of electric telescopic rod 6 and realize the control of filter screen 11 cleaning operation; Collection box 8: It is slidably connected inside the filter box 3 and contacts the surface of the corresponding filter screen 11. It is used to collect the impurities scraped off the surface of the filter screen 11 by the scraper 12 to avoid the accumulation of impurities and affect gas filtration. Replacement frame 9: It is slidably connected to the sliding groove 20 at the bottom of the filter box 3. Multiple threaded holes 15 and two rotating grooves 16 are opened on one side. The rotating groove 16 is opened with an installation groove 10 for installing molecular sieve 14. The molecular sieve 14 can be replaced alternately by sliding. At the same time, it is fixed by the cooperation of screw 18 and threaded hole 15. Mounting slot 10: It is formed inside the rotating slot 16 of the replacement frame 9 to provide sliding mounting space for the molecular sieve 14, so that the molecular sieve 14 can be stably placed on the replacement frame 9. Filter screen 11: Slidingly installed inside the filter box 3, located in the gas flow path, used to intercept larger particulate impurities in the gas, providing pre-filtration for the subsequent purification treatment of molecular sieve 14, and its surface is in contact with scraper 12 and collection box 8. Scraper 12: It is fixedly connected to the telescopic end of the electric telescopic rod 6 and contacts the surface of the corresponding filter screen 11. Under the drive of the electric telescopic rod 6, it can move on the surface of the filter screen 11 and scrape the impurities accumulated on the filter screen 11 into the collection box 8. Rotary limiting plate 13: Rotary and connected to the corresponding rotating groove 16 of the replacement frame 9, used to limit the molecular sieve 14 installed in the installation groove 10, and prevent the molecular sieve 14 from falling out of the installation groove 10. A rubber positioning plug 19 is fixedly connected to one side. Molecular sieve 14: It is slidably connected to the corresponding mounting slot 10 of the replacement frame 9 and located on the gas flow path inside the filter box 3. After being filtered by the filter screen 11, it further adsorbs tiny impurities and moisture in the gas to achieve gas purification. Threaded holes 15: Multiple holes are provided on one side of the replacement frame 9. They are used to cooperate with screws 18. When screws 18 are screwed into threaded holes 15, the replacement frame 9 is fixed. When screws are screwed out, the replacement frame 9 is released from the fixation. Rotation slot 16: Two are formed on one side of the replacement frame 9, and the mounting slot 10 and positioning slot 17 are formed inside to provide rotational mounting space for the rotation limit plate 13; Positioning groove 17: It is formed inside the rotating groove 16 of the changing frame 9 and is used to cooperate with the rubber positioning plug 19 on the rotating limit plate 13. The rotating limit plate 13 is fixed by the interference fit of the rubber positioning plug 19. Screw 18: There are two screws, both of which are slidably installed on the filter box 3. One end can be connected to the internal thread of the corresponding threaded hole 15 on one side of the replacement frame 9 to fix or release the replacement frame 9, thereby enabling the alternating replacement of the molecular sieve 14. Rubber positioning plugs 19: are fixedly connected to the side of the two rotating limiting plates 13 near the replacement frame 9, and can be interference-fitted with the positioning grooves 17 in the corresponding rotating grooves 16 to fix the position of the rotating limiting plates 13 and ensure their limiting effect on the molecular sieve 14.
[0020] Example 1: like Figure 1-5 As shown, during normal operation, both molecular sieves 14 are in the filter box 3 for drying. When one of the molecular sieves 14 becomes saturated and needs to be replaced, the replacement frame 9 slides in the sliding groove 20, and the mounting groove 10 containing the saturated molecular sieve 14 slides outside the filter box 3, allowing the new molecular sieve 14 to slide inside the filter box 3. Then, the rotating limiting plate 13 is rotated to limit the two slid molecular sieves 14. Subsequently, the replacement frame 9 is further fixed by the threaded connection between the screw 18 and the threaded hole 15. At this time, the other molecular sieve 14 continues to work, achieving replacement without stopping the machine and ensuring the continuity of hydrogen purification. During this process, the filter screen 11 can filter a small amount of impurities, and the collection box 8 temporarily stores the impurities.
[0021] Example 2: like Figure 4-5As shown, the rubber positioning plug 19 is fixed to the rotating limiting plate 13. When the rotating limiting plate 13 rotates to the appropriate position, the rubber positioning plug 19 will be interference-fitted into the positioning groove 17. The friction and extrusion forces generated by this interference fit can provide additional fixing force for the molecular sieve 14, preventing the molecular sieve 14 from shaking or shifting in the mounting groove 10 due to gas flow and equipment vibration during gas purification, thereby ensuring the stable effect of the molecular sieve 14 on gas purification.
[0022] Furthermore, when using this device, the gas first enters the deoxygenation pretreatment component 2 for deoxygenation pretreatment. After treatment, the gas is transported to the filter box 3 through a pipeline. In the filter box 3, the gas passes through the filter screen 11 and the molecular sieve 14 in sequence for filtration and purification. The filter screen 11 can intercept larger particulate impurities in the gas, while the molecular sieve 14 further adsorbs small impurities and moisture in the gas. Finally, the pure gas is discharged from the exhaust pipe on the side of the filter box 3 away from the deoxygenation pretreatment component 2.
[0023] When the surface of the filter screen 11 needs to be cleaned regularly, the electric telescopic rod 6 is controlled to work. The telescopic end of the electric telescopic rod 6 drives the scraper 12 to move on the surface of the filter screen 11, scraping the impurities accumulated on the filter screen 11 into the collection box 8, so as to avoid the impurities affecting subsequent operations.
[0024] When it is necessary to replace the molecular sieve 14, rotate the limiting plate 13 to disengage the rubber positioning plug 19 from the positioning groove 17. At this time, the new molecular sieve 14 can be slid into the corresponding installation groove 10. Rotate the limiting plate 13 to allow the rubber positioning plug 19 to be inserted into the positioning groove 17 with an interference fit, thus achieving initial fixation of the molecular sieve 14. Then, rotate the screw 18 to unscrew it from the threaded hole 15 on one side of the replacement frame 9, thereby releasing the fixation of the replacement frame 9. Next, slide the replacement frame 9 to send the new molecular sieve 14 into the filter box 3. Finally, screw the screw 18 into the corresponding threaded hole 15 to complete the fixation of the replacement frame 9 and realize the alternating replacement of the molecular sieve 14.
[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
