Description

Technical Field

[0001] This utility model relates to the field of hydrogen production, specifically a drying device for a hydrogen generator. Background Technology

[0002] A hydrogen generator is a hydrogen production device and one of the most widely used pieces of equipment in laboratories. It mainly consists of an electrolytic cell, a pure water tank, a hydrogen / water separator, a collector, a dryer, sensors, a pressure regulating valve, and a switching power supply. Hydrogen is produced simply by electrolyzing pure water. After power is applied, hydrogen is produced at the cathode of the electrolytic cell, and oxygen is produced at the anode. The hydrogen then enters the hydrogen / water separator. The oxygen is released into the atmosphere. During the hydrogen production process in the hydrogen generator, the hydrogen needs to be dehumidified and dried to remove the moisture generated during hydrogen production.

[0003] In practical use, the drying tubes of existing hydrogen generators are mostly connected by threads, which increases the replacement time and makes it inconvenient to improve the convenience of maintenance and replacement. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a drying device for a hydrogen generator.

[0005] This utility model provides a drying device for a hydrogen generator, including a drying tube and an indicator label adhered to the surface of the drying tube. The top end of the drying tube is fixedly connected to an upper connecting tube, and the bottom end of the drying tube is fixedly connected to a lower connecting tube. The top surface of the upper connecting tube and the bottom surface of the lower connecting tube are both fixedly connected to a sealing inner tube. A sealing top cover is inserted into the top surface of the sealing inner tube. Limiting components are fixedly connected to both sides of the surfaces of the lower connecting tube and the sealing top cover.

[0006] Preferably, the limiting member has limiting holes on both sides, and a telescopic support column and a support spring are fixedly connected inside the limiting holes. The support spring is sleeved on the surface of the telescopic support column, and a limiting block is fixedly connected to one end of both the telescopic support column and the support spring.

[0007] Preferably, a sealing lower cover is inserted into the surface of one of the sealing inner tubes, and the sealing lower cover is fixedly connected to both sides of the surface of the connecting upper tube with a snap-fit ​​member. Each snap-fit ​​member has a snap-fit ​​hole on both sides, and the snap-fit ​​hole is adapted to the limiting block.

[0008] Preferably, the outer surfaces of both inner sealing tubes are fitted with sealing gaskets, and the sealing gaskets are made of rubber.

[0009] Preferably, the inner walls of both the upper and lower connecting pipes are threaded with a cover mesh, and both sides of the surface of the cover mesh are rotatably connected with a screwing component.

[0010] Preferably, the top surface of the sealing upper cover and the bottom surface of the sealing lower cover are both fixedly connected to a connecting pipe, and the surface of the connecting pipe is threadedly connected to a limit connecting cap.

[0011] Preferably, the interior of the drying tube is filled from bottom to top with barrier material one, color-changing silica gel desiccant, barrier material two, 13X molecular sieve, barrier material three, carbon nanosphere material and barrier material four, and the material of barrier material one, barrier material two, barrier material three and barrier material four is cotton.

[0012] Compared with related technologies, the present invention provides the following beneficial effects:

[0013] By incorporating color-changing silica gel desiccant, 13X molecular sieve, and carbon nanospheres, the connecting pipe of the drying device is connected to the inlet and outlet of the hydrogen generator. This allows for multiple drying processes of the hydrogen produced by the hydrogen generator, ensuring the purity of the dried hydrogen and improving the drying effect.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1 to 5 A drying device for a hydrogen generator includes a drying tube 1 and an indicator label 23 adhered to the surface of the drying tube 1. The indicator arrows on the indicator label 23 facilitate quick and easy identification of the top and bottom of the drying tube 1. An upper connecting tube 2 is fixedly connected to the top of the drying tube 1, and a lower connecting tube 3 is fixedly connected to the bottom of the drying tube 1. A sealing inner tube 4 is fixedly connected to both the top surface of the upper connecting tube 2 and the bottom surface of the lower connecting tube 3. A sealing top cover 5 is inserted into the top surface of the sealing inner tube 4. The insertion of the sealing inner tube 4 into the sealing top cover 5 helps to increase the sealing performance of the drying tube 1 and reduce hydrogen leakage. Limiting elements 6 are fixedly connected to both sides of the surfaces of the lower connecting tube 3 and the sealing top cover 5.

[0023] Of particular note is that limit holes are provided on both sides of the limiting member 6. A telescopic support column 7 and a support spring 8 are fixedly connected inside the limit holes. The support spring 8 is sleeved on the surface of the telescopic support column 7. A limit block 9 is fixedly connected to one end of both the telescopic support column 7 and the support spring 8. A sealing lower cover 10 is inserted into the surface of one of the sealing inner tubes 4. A snap-fit ​​member 11 is fixedly connected to both sides of the sealing lower cover 10 and the surface of the connecting upper tube 2. A snap-fit ​​hole is provided on both sides of the snap-fit ​​member 11, and the snap-fit ​​hole is adapted to the limit block 9.

[0024] When assembling the sealing upper cover 5 and sealing lower cover 10 with the drying tube 1, first press the limiting block 9 to retract it into the limiting hole, then insert the limiting piece 6 into the snap-fit ​​piece 11. The support spring 8 is elastic and releases elastic potential energy, which brings the telescopic support column 7 and the limiting block 9 back to their original state, so that the limiting block 9 is snapped into the insertion hole and fixed.

[0025] Both inner sealing tubes 4 have sealing gaskets 12 fitted on their outer surfaces. The sealing gaskets 12 are made of rubber and are placed at the connection points between the lower tube 3 and the lower sealing cover 10, and between the upper tube 2 and the upper sealing cover 5, which helps to increase their sealing performance.

[0026] Both the inner walls of the upper pipe 2 and the lower pipe 3 are threaded with a baffle mesh 13. Both sides of the baffle mesh 13 are rotatably connected with a screwing component. Lifting the screwing component makes it easy to rotate the baffle mesh 13 for disassembly and installation. The baffle mesh 13 facilitates the passage of hydrogen while preventing various dried substances from leaking out of the drying pipe 1.

[0027] The top surface of the sealing cover 5 and the bottom surface of the sealing cover 10 are both fixedly connected to a connecting pipe 14. The surface of the connecting pipe 14 is threadedly connected to a limit connecting cap 15. One connecting pipe 14 is connected to the hydrogen outlet of the hydrogen generator, and the other connecting pipe 14 is connected to an external pipeline that needs to use hydrogen.

[0028] In addition, the interior of the drying tube 1 is filled from bottom to top with barrier material 16, color-changing silica gel desiccant 17, barrier material 28, 13X molecular sieve 19, barrier material 30, carbon nanosphere material 21, and barrier material 42. The materials of barrier material 16, barrier material 28, barrier material 30, and barrier material 42 are all cotton. The color-changing silica gel desiccant 17, 13X molecular sieve 19, and carbon nanosphere material 21 all have moisture absorption functions and can be regenerated. The color indicator in the color-changing silica gel desiccant 17 makes it easy to observe whether the desiccant can continue to absorb moisture and dry. At the same time, the pore size of 13X molecular sieve 19 is small, which can increase the moisture absorption performance. In addition, carbon nanosphere material 21 has a very high specific surface area and pore structure, which allows it to adsorb a large amount of water or other substances, thereby helping to reduce the presence of moisture in hydrogen and improve the drying effect.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
