[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Refer to Figure 1 - Figure 3 , an embodiment provided by the present invention: It includes a lower tank body 1, a first fixing block 2 is fixedly connected inside the lower tank body 1, a motor 3 is fixedly connected inside the first fixing block 2, a first gear 4 is fixedly connected to the output end of the motor 3, a stirring block 6 is rotatably connected inside the first fixing block 2, a second gear 5 is fixedly connected to the top of the stirring block 6, the first gear 4 meshes with the second gear 5, an air inlet 8 is fixedly connected inside the lower tank body 1, a filter tank 7 is fixedly connected to the outer wall of the air inlet 8, the outer wall of the filter tank 7 is fixedly connected inside the lower tank body 1, an upper tank body 12 is fixedly connected to the top of the lower tank body 1, a molecular sieve 11 is fixedly connected inside the upper tank body 12, activated carbon 10 is fixedly connected inside the upper tank body 12, an air outlet 9 is fixedly connected inside the upper tank body 12, and a sealing assembly is arranged on the outer wall of the upper tank body 12;

[0024] Specifically, when using this multi-stage hydrogen filtration and purification device, first start the motor 3. Subsequently, the motor 3 drives the first gear 4 fixedly connected to the bottom to rotate. At this time, the first gear 4 drives the meshing second gear 5 to rotate. At the same time, the second gear 5 drives the stirring block 6 fixedly connected to the bottom to rotate. After the stirring block 6 starts to rotate, hydrogen is introduced from the air inlet 8. Subsequently, the hydrogen enters the filtration tank 7 through the air inlet 8. After the hydrogen comes out of the filtration tank 7, it rises through the molecular sieve 11. The purpose of using the molecular sieve 11 in this structure is that the molecular sieve 11 is a porous material with a specific pore size, which can selectively adsorb molecules of specific sizes and shapes and can be used to remove water, sulfides, and some organic substances in hydrogen. After the hydrogen passes through the molecular sieve 11, it continues to rise through the activated carbon 10. The purpose of using the activated carbon 10 in this structure is that the activated carbon 10 is a porous material with strong adsorption capacity, which can effectively remove impurities in hydrogen. After the hydrogen passes through the activated carbon 10, it continues to rise and enters the air outlet 9.

[0025] Refer to Figure 1 - Figure 3 , the sealing assembly includes a steel ring 15 and a gasket 16. The outer wall of the upper tank body 12 is fixedly connected with a steel ring 15, and the outer wall of the upper tank body 12 is fixedly connected with a gasket 16. The gasket 16 is fixedly connected to the bottom of the steel ring 15. A fixing bolt 14 is threadedly connected inside the steel ring 15. An outlet 18 is fixedly connected inside the filtration tank 7, and an inlet 17 is fixedly connected inside the filtration tank 7. A handle 13 is fixedly connected to the outer wall of the upper tank body 12. The outer wall of the outlet 18 is fixedly connected inside the lower tank body 1, and the outer wall of the inlet 17 is fixedly connected inside the lower tank body 1. The bottom of the lower tank body 1 is fixedly connected with a support column 24, and a second fixing block 19 is fixedly connected to one side of the outer wall of the outlet 18;

[0026] Specifically, when it is necessary to replace the molecular sieve 11 and the activated carbon 10 inside the upper tank body 12, turn the fixing bolt 14, and then lift the upper tank body 12 through the handle 13 to replace the molecular sieve 11 and the activated carbon 10. After the replacement is completed, place the upper tank body 12 on the top of the lower tank body 1, and then tighten the fixing bolt 14. A gasket 16 is fixedly connected to the bottom of the steel ring 15. The reason for placing the gasket 16 is to prevent hydrogen from leaking through the gap between the lower tank body 1 and the upper tank body 12.

[0027] Refer to Figure 2 - Figure 4 , one side of the outer wall of the second fixing block 19 is rotatably connected with a lid 20, the other side of the outer wall of the outlet 18 is fixedly connected with a limiting block 23, a limiting bolt 25 is threadedly connected inside the limiting block 23, one side of the outer wall of the lid 20 is fixedly connected with a second fixing bolt 21, and the outer wall of the second fixing bolt 21 is rotatably connected with a rotating block 22;

[0028] Specifically, when the filtrate in the hydrogen multi-stage filtration and purification device needs to be replaced, first rotate the limit bolt 25 on the liquid outlet 18, then rotate the rotating block 22 to disengage the limit block 23, and then open the cover 20 to release the filtrate in the filter tank 7. After the filtrate is completely released, close the cover 20, rotate the rotating block 22 to the limit block 23, then tighten the limit bolt 25, and then rotate the limit bolt 25 on the liquid inlet 17, then rotate the rotating block 22 to disengage the limit block 23, and then open the cover 20 to add the filtrate.

[0029] Working principle: When using the hydrogen multi-stage filtration and purification device, first start the motor 3. Because the output end of the motor 3 is fixedly connected to the gear 1 4, the gear 1 4 is forced to rotate, and then the gear 1 4 drives the meshing gear 2 5 to rotate. At this time, the gear 2 5 is forced to drive the stirring block 6 fixedly connected at the bottom. The stirring block 6 starts to stir the filtrate in the filter pool 7, and then outputs hydrogen to the air inlet 8. The hydrogen enters the filter pool 7 through the air inlet 8. After the hydrogen passes through the filter pool 7, it moves upward and then passes through the molecular sieve 11. After the hydrogen passes through the molecular sieve 11, it enters the active The carbon 10 finally enters the gas outlet 9 to complete the multi-stage filtration and purification of hydrogen. When the filtrate in the filter tank 7 needs to be replaced, first loosen the limit bolt 25, then rotate the rotating block 22, and then turn the cover 20 to rotate to the right rear, that is, open the liquid outlet 18 to release the filtrate. When the filtrate is released, close the cover 20. After the cover 20 is close to the liquid outlet 18, rotate the rotating block 22 to the left front, then tighten the limit bolt 25, and then loosen the limit bolt 25 on the liquid inlet 17, rotate the rotating block 22, and open the cover 20 to add the filtrate.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
