Description

Technical Field

[0001] The utility model belongs to the technical field of feeding devices, in particular to a feeding device for a hydrogen generator. Background Art

[0002] Aluminum hydrogen generator is a device that uses aluminum as raw material to produce hydrogen. Specifically, aluminum hydrogen generator usually produces hydrogen through a chemical reaction between aluminum and alkali (such as sodium hydroxide); this hydrogen production method is mainly based on the replacement reaction between aluminum and alkali, that is, aluminum reacts with alkaline solution (such as sodium hydroxide solution) to generate metaaluminate and hydrogen. During the reaction, aluminum, as a reducing agent, is oxidized into aluminum ions, while the hydroxide ions in the alkali are reduced to hydrogen.

[0003] In order to continue the reaction, aluminum needs to be continuously added to the reaction tank to achieve continuous hydrogen production. Manual operation has poor precision, high work intensity and high labor costs. The existing feeding device for hydrogen production cannot accurately control the single feeding amount, and cannot adjust the single feeding amount according to the actual reaction situation and requirements, which causes certain troubles to the feeding step of hydrogen production.

[0004] In order to solve the above problems, a hydrogen generator feeding device is proposed in the present application. Utility Model Content

[0029] Among them, a gear ring 7 is provided at the bottom of the rotating drum 4, and the gear ring 7 is located on the outer side of the bottom of the feeding box 1. A gear 10 is meshed on the gear ring 7. A mounting plate 8 is fixed at the bottom of the feeding box 1, and a quantity control motor 9 is fixed on the mounting plate 8. The gear 10 is fixed at the output end of the quantity control motor 9. In this embodiment, the gear ring 7 is extended and installed on the bottom of the rotating drum 4 and the outer side of the bottom of the feeding box 1, which can provide avoidance space for the movement of the quantity control box 6, and can also ensure the stable rotation of the rotating drum 4 and the partition 5, and will not affect the feeding cavity.

[0030] Among them, a guide sleeve 11 for the sliding of the quantity control box 6 is provided on the side wall of the rotating drum 4, and a vertically arranged two-way screw 12 is provided inside the rotating drum 4. Both ends of the two-way screw 12 are threadedly connected with an internal thread seat 13, and a connecting rod 14 is hinged between the internal thread seat 13 and the quantity control box 6. In this embodiment, the guide sleeve 11 limits the moving direction of the quantity control box 6, and also ensures the moving stability of the quantity control box 6. The position of the quantity control box 6 will not affect the feeding work, and can also be adjusted according to actual conditions, and has good adaptability.

[0031] Among them, the connecting rods 14 are arranged in a symmetrical group up and down. One end of the two connecting rods 14 is hinged to the control box 6 at the same time, and the other end is hinged to the two internal threaded seats 13 respectively. In this embodiment, the symmetrically grouped connecting rods 14 can ensure the reliability of the connection structure while ensuring flexible connection.

[0032] Among them, the connecting rods 14 are distributed in a circle in multiple groups and the number is equal to the control boxes 6. The angles of the two connecting rods 14 in each group are adjusted to make the control boxes 6 slide horizontally on the guide sleeve 11. In this embodiment, multiple control boxes 6 are connected to the internal threaded seat 13 through the connecting rods 14, and then the positions of the multiple control boxes 6 are adjusted by changing the distance between the two internal threaded seats 13, which has the advantages of good linkage effect, high consistency and convenient operation.

[0033] Among them, a feeding motor 15 whose output end is connected to the bidirectional lead screw 12 is fixed at the bottom of the rotating drum 4. After the bidirectional lead screw 12 rotates, it drives the two internal thread seats 13 to move synchronously in different directions through the spiral. In this embodiment, the cooperation of the bidirectional lead screw 12, the internal thread seat 13 and the feeding motor 15 makes the structure more compact, and the bidirectional lead screw 12 and the internal thread seat 13 are both located inside the rotating drum 4, with a reasonable structural distribution and will not occupy excess space.

[0034] It can be understood that, first, a disc-type feed box 1 is set up, and then a partition 5 for continuous feed is set up inside the feed box 1, which can effectively separate the connecting ends of the feed pipe 2 and the discharge pipe 3. At the same time, the cavity formed between the partition 5 and the feed box 1 can also ensure the consistency of the feed amount each time; secondly, an adjustable quantity control box 6 is set in the cavity formed by the feed box 1 and the partition 5. The quantity control box 6 can adjust the single feed amount of the cavity according to the actual reaction situation, and can be adjusted according to the actual use situation. It has flexible controllability, thereby ensuring the stable and reliable hydrogen production work.

[0035] A specific application of this embodiment is: the upper end of the feed pipe 2 is connected to the hopper, and the lower end of the discharge pipe 3 is connected to the feed port of the hydrogen generator. Materials are added into the hopper, and the materials fall directly into the cavity directly below the feed pipe 2 through the feed pipe 2. At this time, the control motor 9 drives the gear 10 to mesh with the ring gear 7, and the ring gear 7 drives the drum 4 and the partition 5 to rotate inside the feed box 1, and rotates one side of the discharge pipe 3 of the material box. When the material is directly above the discharge pipe 3, it will be directly added to the hydrogen generator through the discharge pipe 3. The feed pipe 2 continuously feeds multiple cavities, and the discharge pipe 3 continuously feeds the materials in multiple cavities into the hydrogen generator;

[0036] When the cavity volume needs to be adjusted: the bidirectional lead screw 12 is driven to rotate inside the drum 4 by the feeding motor 15, and the bidirectional lead screw 12 drives the two internal thread seats 13 at the upper end to move synchronously in different directions through the spiral. Due to the movement of the internal thread seats 13 and the action of the connecting rod 14, the control box 6 is prompted to slide horizontally in the guide sleeve 11, and the purpose of adjusting the cavity volume is achieved by the amount of the control box 6 entering the cavity.
