Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen storage tanks, in particular to a metal hydride hydrogen storage tank. Background Art

[0002] Metal hydride is a special compound whose molecules contain metal atoms and hydrogen atoms. In metal hydride, hydrogen atoms are adsorbed or combined into the lattice structure of metal atoms to form chemical bonds of hydride. Metal hydride hydrogen storage tank is a device for storing hydrogen, which uses metal hydride as hydrogen absorption material. This hydrogen storage tank achieves hydrogen storage by allowing metal hydride to absorb hydrogen under certain conditions, and adsorbing hydrogen into the lattice of metal hydride.

[0003] In the prior art, the announcement number is: (CN214369284U), and the patent name is a Chinese utility model patent for a metal hydride hydrogen storage tank, which discloses a hydrogen storage tank. The patent records that heat will be transferred to the heat exchange jacket through the tank body, and the water pump can be started. Under the action of the water pump, the water inside the tank body can be transported to the inside of the heat exchange tank through the delivery pipe, and the heat inside the heat exchange jacket can be exchanged, and then returned to the inside of the tank body through the reflux pipe. The water inside the tank body continuously exchanges heat with the heat exchange jacket inside the heat exchange tank, and the heat is recycled and stored inside the tank body. Then, when the metal hydride releases hydrogen and needs to absorb heat, the water pump can be started. Under the action of the water pump, the hot water inside the tank body can be transported to the inside of the heat exchange tank through the delivery pipe, and the inside of the heat exchange jacket can be heated, thereby heating the surface of the tank body, realizing a technical solution for heat recycling. In this solution, due to long-term hydrogen production, a large amount of hydrolysis products will remain inside the tank. Since the device cannot be disassembled, it is time-consuming and labor-intensive to clean it. In order to solve this technical problem, the utility model proposes a metal hydride hydrogen storage tank. Utility Model Content

At the same time, the latch 7 is slidably connected to the inside of the inner hole 9. The elastic action of the spring 6 will bounce the latch 7 into the inner hole 9. At the same time, the inner hole 9 will limit the movement of the latch 7, and the connecting plate 8 is slidably connected to the inside of the fixed shell 4, and the fixed shell 4 plays the role of limiting the connecting plate 8. A sliding column 10 is fixedly connected to the other side of the fixed plate 5. At the same time, a transverse groove 3 and two vertical grooves 11 are provided on the outer side of the bottom of the tank body 2. At the same time, the inner diameters of the vertical groove 11 and the transverse groove 3 correspond to the diameters of the sliding column 10, and the sliding column 10 is slidably connected to the inside of the transverse groove 3 and the vertical groove 11, and the transverse groove 3 and the vertical groove 11 play the role of limiting the sliding column 10. The base 1 rotates on the tank body 2 through the sliding column 10, and an installation groove 18 is provided inside the base 1. At the same time, the tank body 2 is slidably connected in the installation groove 18. The mounting groove 18 corresponds to the tank body 2 to prevent gas discharge. A water storage tank 14 is provided inside the base 1. At the same time, a pair of mounting plates 15 are provided inside the base 1, and the mounting plates 15 are fixedly connected to the two sides of the water storage tank 14 respectively.
