Description

Technical Field

[0002] Solid-state hydrogen storage is a technology that converts hydrogen into solid hydride through special hydrogen storage materials. This technology has the advantages of low hydrogen storage pressure, high volume hydrogen storage density, and the ability to purify hydrogen. At the same time, its disadvantages are low mass hydrogen storage density and the need for heat exchange during hydrogen charging and discharging. The solid-state hydrogen storage tank is the most basic unit of the solid-state hydrogen storage device. During the production of the hydrogen storage tank, the interior of the hydrogen storage tank needs to be cleaned, and the inner wall of the hydrogen storage tank needs to be dried after cleaning. Generally, the drying process of the hydrogen storage tank directly puts the hydrogen storage tank into a drying box for drying, which has the following defects:

[0003] When the hydrogen storage tank is dried in a drying box, the heat first acts on the outer wall of the hydrogen storage tank, and then is transferred to the inner wall. The moisture on the inner wall evaporates under the action of the heat, completing the drying, resulting in poor heating effect on the inner wall and low drying efficiency. Utility Model Content

The motor 808 is fixedly installed inside the mounting frame 801, and the horizontal long tube 1 is away from the end box 201. A fixing ring 809 is installed on the outer wall at one end, and a limit clamp 810 is clamped on the top of the fixing ring 809. The limit clamp 810 is used to limit the movement of the horizontal long tube 1 along the length direction and will not affect the rotation of the horizontal long tube 1. A second cylinder 811 is installed on the top of the mounting frame 801, and the output end of the second cylinder 811 is fixedly connected to the fixing ring 809. A moving frame 802 is provided at the bottom of the mounting frame 801, and two first cylinders 803 are symmetrically installed on the top of the moving frame 802.

[0028] Working principle: When working, first clamp and fix the hydrogen storage tank horizontally, control the output end of the first cylinder 803 to extend, adjust the height of the horizontal long tube 1 to the coaxial position with the hydrogen storage tank, open the moving frame 802, move the horizontal long tube 1, and insert the end of the horizontal long tube 1 into the hydrogen storage tank;

[0029] The electromagnet 209 is controlled to be energized to generate a repulsive force on the magnetic block 208, and the movable plate 202 is pushed to move under the action of the repulsive force, thereby pushing the absorbent cotton roller 206 on the mounting plate 204 to contact the inner wall of the hydrogen storage tank, so as to facilitate the drying of hydrogen storage tanks with different inner diameters, and the heating block 205 is controlled to be energized to generate heat, and then the inner wall of the hydrogen storage tank is heated and dried, and at the same time, the motor 808 is turned on to rotate the gear 807, and the gear 807 is meshed with the tooth groove 806, thereby driving the exhaust pipe 5 to rotate, and at the same time, the exhaust pipe 5 is slidably connected with the horizontal long tube 1 through the guide bar 6 and the guide groove 4, so that the horizontal long tube 1 rotates together with the exhaust pipe 5 When rotating, the heating block 205 is constantly close to the inner wall of the hydrogen storage tank in the circumferential direction, which is convenient for uniformly drying the inner wall of the hydrogen storage tank. At the same time, the absorbent cotton roller 206 is constantly moving on the inner wall of the hydrogen storage tank, which can wipe the moisture on the inner wall of the hydrogen storage tank and improve the drying efficiency of the hydrogen storage tank. When the inner wall of the hydrogen storage tank of a certain width is dried, the second cylinder 811 is turned on, so that the output end of the second cylinder 811 extends to push the limit clip 810 to move toward the hydrogen storage tank. Since the limit clip 810 is clamped on the outside of the fixing ring 809, the horizontal long tube 1 is pushed to move a certain distance into the hydrogen storage tank, which is convenient for comprehensive drying of the inner wall of the hydrogen storage tank.

[0030] During the rotation of the exhaust pipe 5, the fan blades 7 are driven to rotate, thereby driving the water vapor generated by heating in the hydrogen storage tank to be discharged through the exhaust hole 3 and the exhaust pipe 5, preventing the water vapor from re-adhering to the inner wall of the hydrogen storage tank after drying and re-liquefying, thereby improving the drying effect.
