[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification

[0024] Embodiment 1

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution: a purification device for hydrogen production by methanol cracking, including an installation substrate 1. The top surface of the installation substrate 1 is fixedly installed with an adsorption tower 2 and an installation seat 3. The adsorption towers 2 are arranged at equal distances on the top surface of the installation substrate 1 to ensure the stability and uniform distribution of the adsorption towers 2 during operation. The adsorption tower 2 can be installed on the installation substrate 1 by means of bolt fixation, welding, or flange connection. These connection methods have high installation strength and stability, can prevent the adsorption tower 2 from shaking during operation, and improve the safety and reliability of the device

[0026] Please refer to Figures 1-5, a slot 4 is provided on the top surface of the mounting base 3, and a plug 5 is slidably connected to the inner wall of the slot 4. The sizes of the slot 4 and the plug 5 are adapted to each other, ensuring a tight connection between the two. Both the slot 4 and the plug 5 are in a "T" - shaped structure. This structural design can effectively prevent the plug 5 from rotating or shifting within the slot 4, ensuring the stability of the mounting plate 6. The top end of the plug 5 is fixedly installed with a mounting plate 6. A sliding plate 7 is disposed through the top end of the mounting plate 6. The top end of the sliding plate 7 is fixedly installed with a support block 8, and the sliding plate 7 is slidably connected to the mounting plate 6. The sliding plate 7 can be installed by means of rail sliding or rolling bearing sliding. This design can reduce friction and improve the smoothness and accuracy of the position adjustment of the support block 8. The support block 8 is in a semi - circular structure, which can better adapt to the shape of the adsorption tower 2 and provide a more stable support. A top block 9 is fixedly installed on the back surface of the support block 8, and a bottom block 10 is fixedly installed on the back surface of the mounting plate 6. The bottom surface of the top block 9 is rotatably connected to a threaded rod 11. Threads are provided inside the bottom block 10, and the threads are engaged with the threaded rod 11. The threaded rod 11 can be connected to the bottom block 10 by means of a ball screw or an ordinary thread. This threaded connection can not only provide high precision and load - bearing capacity, but also realize the position adjustment of the top block 9 and the support block 8 by rotating the threaded rod 11, so as to adapt to adsorption towers 2 of different heights and improve the applicability of the device. During the working process, the staff can use tools to turn the threaded rod 11, so that the top block 9 drives the sliding plate 7 to slide in the mounting plate 6, and then adjust the position of the support block 8 to adapt to adsorption towers 2 of different heights, thereby improving the adaptability and versatility of the device.

[0027] Embodiment Two

[0028] Please refer to Figures 4-5 , a pressure display mechanism is provided at the bottom end of the adsorption tower 2. The pressure display mechanism includes a pressure gauge 12. The pressure gauge 12 is fixedly installed at the bottom end of the adsorption tower 2 and can real - time display the pressure situation inside the adsorption tower 2, ensuring the safety and efficiency of the purification process. An extension block 13 is fixedly installed on the surface of the pressure gauge 12. A rotating rod 14 is rotatably connected to the surface of the extension block 13. A brush plate 15 is fixedly installed on the surface of the rotating rod 14. The rotational connection between the rotating rod 14 and the extension block 13 can be realized by means of a rolling bearing or a pin shaft connection, which can reduce friction and ensure the flexible rotation of the brush plate 15, facilitating the cleaning of the surface of the pressure gauge 12. A brush hair 16 and a rubber column 17 are fixedly installed on the back surface of the brush plate 15. The brush hair 16 can effectively clean the surface of the pressure gauge 12. The rubber column 17 is in contact with the extension block 13, and the position of the brush plate 15 is limited by the frictional force, preventing the brush plate 15 from rotating randomly in the non - working state and ensuring the stability of the device and the convenience of operation.

[0029] Working principle: hydrogen can be purified by passing it into the adsorption tower 2, and the support block 8 can be set to stabilize the position of the adsorption tower 2, thereby improving the stability of the adsorption tower 2, especially in extreme weather, to prevent the adsorption tower 2 from shaking and collapsing. At the same time, the staff can also use tools to twist the threaded rod 11. At this time, since the bottom block 10 is provided with threads, the threaded rod 11 moves in the bottom block 10, and the threaded rod 11 can then drive the top block 9 to move, and the top block 9 can then drive the slide plate 7 to slide in the mounting plate 6, and at the same time drive the support block 8 to move, and the position of the support block 8 can be adjusted at this time. The utility model can adapt to adsorption towers 2 of different heights, and improves versatility. When the support block 8 is not in use, the staff only needs to lift or hoist the mounting plate 6 upwards, and the mounting plate 6 can then drive the plug block 5 to leave the slot 4, and then the support block 8 can be removed. The utility model can effectively improve the stability of the adsorption tower 2 under extreme weather conditions through the setting of the support block 8, and prevent equipment damage or safety hazards caused by shaking or collapse. In addition, through the linkage of the threaded rod 11, the top block 9, the slide plate 7 and the support block 8, the position of the support block 8 can be flexibly adjusted to adapt to adsorption towers 2 of different heights, thereby improving the versatility of the device and adapting to More types of adsorption tower 2 configurations, and when the support block 8 is not in use, the staff can lift or hoist the mounting plate 6 to easily remove the support block 8, which simplifies the maintenance and adjustment process of the equipment and improves the convenience and efficiency of operation. The internal pressure of the adsorption tower 2 can be displayed by the set pressure gauge 12. At the same time, when there are many stains on the surface of the pressure gauge 12, the staff only needs to twist the rotating rod 14, and the rotating rod 14 can then drive the brush plate 15 to rotate, and the brush plate 15 can then drive the bristles 16 to rub the surface of the pressure gauge 12. At this time, the pressure gauge 12 can be cleaned, and the rubber column 17 can rub the extension block 13. The friction force generated can limit the position of the brush plate 15 to prevent the brush plate 15 from moving around. The utility model can display the internal pressure of the adsorption tower 2 in real time by setting a pressure gauge 12, so that the operator can understand the operating status of the equipment in time to ensure the safety and efficiency of the purification process. When there are many stains on the surface of the pressure gauge 12, the staff can clean the surface of the pressure gauge 12 through simple operations, which avoids inaccurate readings caused by stains and ensures the reliability of pressure monitoring. The friction force between the rubber column 17 and the extension block 13 provides a limiting function for the position of the brush plate 15 to prevent the brush plate 15 from moving around when it is idle.
