Technical Field
[0001] This utility model belongs to the technical field of microbial hydrogen production equipment, and specifically relates to an efficient microbial hydrogen production device. Background Art
[0002] In today's global energy pattern, traditional fossil fuels not only have limited reserves, but their extraction and use also bring huge pressure to the environment, such as greenhouse gas emissions, air pollution, and ecological damage. Therefore, finding sustainable and clean alternative energy sources has become an urgent task. As an ideal clean energy source, hydrogen energy has significant advantages such as high combustion calorific value and pollution-free products, and has broad application prospects in the energy field.
[0003] Microbial hydrogen production technology has gradually become an important direction in hydrogen energy research due to its unique advantages. Fermentation is one of the key links in the process of microbial hydrogen production. However, existing microbial hydrogen production devices have many deficiencies during the fermentation process, seriously restricting the hydrogen production efficiency and quality.
[0004] The fermentation tanks used in traditional microbial hydrogen production devices usually have relatively simple and inefficient stirring methods. Common stirring methods often rely only on a single rotating shaft to drive the stirring blades for stirring. This method has problems such as limited stirring range and uneven stirring force. Due to insufficient stirring, microorganisms and substrates cannot be evenly mixed, resulting in microorganisms not being able to fully contact the substrates, affecting their metabolism and hydrogen production efficiency.
[0005] In some fermentation tanks, due to incomplete stirring, stirring dead zones are likely to appear. In these dead zone areas, microorganisms and substrates are not effectively stirred for a long time, resulting in inconsistent local reaction conditions. In some areas, microorganisms grow and metabolize excessively, while in other areas, the reaction is insufficient, not only reducing the overall fermentation efficiency but also possibly leading to unstable product quality.
[0006] Especially for the materials at the bottom of the fermentation tank, due to the action of gravity and the limitations of traditional stirring methods, it is often difficult to be fully stirred. The bottom materials are prone to deposition and caking, hindering the effective contact and reaction between microorganisms and substrates, and further affecting the hydrogen production rate and output.
[0007] Therefore, we propose an efficient microbial hydrogen production device that ensures that the materials in all areas of the fermentation tank can be fully and effectively stirred, thereby creating a good environment for the growth and metabolism of microorganisms and improving the hydrogen production efficiency and quality. Content of the Utility Model
[0008] The purpose of this utility model is to provide an efficient microbial hydrogen production device, which ensures that the materials in each area of the fermentation tank can be fully and effectively stirred, thereby creating a good environment for the growth and metabolism of microorganisms and improving the production efficiency and quality of hydrogen.
[0009] The technical solution adopted by this utility model is as follows:
[0010] An efficient microbial hydrogen production device includes a fermentation tank cylinder body, on which a sealing cover and a rotating assembly are arranged. At the bottom of the sealing cover, two symmetric first connecting plates are provided, and on the opposite sides of the two first connecting plates, first magnetic surfaces are provided. On the inner wall of the fermentation tank cylinder body, two symmetric second connecting plates are provided, and at the bottom of the two second connecting plates, second magnetic surfaces are provided. A stirring assembly is arranged on the rotating assembly;
[0011] The stirring assembly includes a rotating rod connected to the rotating assembly. At the top of the rotating rod, a connecting disk is installed. A plurality of sliding grooves are arrayed on the connecting disk. Inside the sliding grooves, a moving assembly is arranged. On the moving assembly, a first slider is provided. At the top of the first slider, a third connecting plate is provided. On the third connecting plate, a third magnetic surface that repels the first magnetic surface is provided. And at the bottom of the first slider, a telescopic assembly is provided. At the bottom of the telescopic assembly, a stirring rod is provided. On the stirring rod, a transverse mixing rod is provided. On the top transverse mixing rod, a fourth magnetic surface that repels the second magnetic surface is provided.
[0012] Furthermore, a feed pipe and a discharge pipe are arranged on the fermentation tank cylinder body.
[0013] Furthermore, an air outlet is arranged on the sealing cover.
[0014] Furthermore, a maintenance window is arranged on the fermentation tank cylinder body.
[0015] Furthermore, the moving assembly includes a fixed shaft arranged inside the sliding groove. A first spring and a first slider are sleeved on the fixed shaft. One side of the first slider is connected to the first spring.
[0016] Furthermore, the telescopic assembly includes a hollow cylinder connected to the first slider. Inside the hollow cylinder, a second spring is arranged. At the bottom of the second spring, a piston disk is provided. At the bottom of the piston disk, a movable rod is provided. The bottom of the movable rod penetrates out of the hollow cylinder and is connected to the stirring rod.
[0017] Furthermore, the rotating assembly includes a motor arranged at the bottom of the fermentation tank cylinder body. The output end of the motor is connected to the rotating rod.
[0018] The technical effects achieved by this utility model are:
[0019] First, add the organic matter to be fermented (such as organic wastewater, biomass resources, etc.) and fermenting microorganisms into the interior of the fermenter cylinder. These microorganisms will utilize the organic matter to produce hydrogen during the subsequent fermentation process. Start the rotating assembly to make it start rotating. The rotating assembly drives the rotating rod to rotate through mechanical connection, and then drives the connection disk installed at the top of the rotating rod to rotate. A plurality of sliding grooves arrayed on the connection disk are provided with moving components, and these moving components move as the connection disk rotates. When the first slider on the moving component rotates to a position corresponding to the first connecting plate on the inner wall of the fermenter cylinder, a repulsive force is generated between the first magnetic surface (provided on the first connecting plate) and the third magnetic surface (provided on the third connecting plate at the top of the first slider). This repulsive force drives the first slider to move in the sliding groove, and then drives the stirring rod and the horizontal mixing rod to move in the horizontal direction. This movement enables the stirring assembly to cover a wider area, ensuring the uniform mixing of microorganisms and substrates. While the stirring rod is moving, the horizontal mixing rod on the stirring rod not only rotates and stirs, but also generates a repulsive force between the fourth magnetic surface on it and the second magnetic surface on the second connecting plate on the inner wall of the fermenter cylinder. This repulsive force causes the stirring rod to move up and down under the action of the telescopic assembly, thereby realizing the deep stirring of the materials at the bottom of the fermenter cylinder. This deep stirring helps to break the material deposition, improve the contact efficiency between microorganisms and substrates, and further promote the production of hydrogen. As the stirring assembly continues to work, the microorganisms and substrates in the fermenter remain in a uniform mixing state, providing favorable conditions for the growth and metabolism of microorganisms. The microorganisms utilize the organic matter for fermentation metabolism, produce hydrogen and release it into the fermenter. This device realizes the efficient and uniform stirring of the materials in the fermenter, improving the fermentation efficiency and hydrogen production. Description of the Drawings

[0028] In order to make the purpose and advantages of the present utility model clearer, the following specifically describes the present utility model in combination with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection of the specific claims of the present utility model.
[0029] As Figures 1-6 shown, the technical solution adopted by the present utility model is specifically as follows: An efficient microbial hydrogen production device includes a fermentation tank cylinder body 1, a sealing cover 2 and a rotating assembly are arranged on the fermentation tank cylinder body 1, two symmetrical first connecting plates 3 are arranged at the bottom of the sealing cover 2, a first magnetic surface is arranged on the opposite side of the two first connecting plates 3, two symmetrical second connecting plates 4 are arranged on the inner wall of the fermentation tank cylinder body 1, a second magnetic surface is arranged at the bottom of the two second connecting plates 4, and a stirring assembly is arranged on the rotating assembly;
[0030] The stirring assembly includes a rotating rod 5 connected to the rotating assembly, a connecting disk 6 is installed at the top of the rotating rod 5, a plurality of chutes 7 are arranged in an array on the connecting disk 6, a moving assembly is arranged inside the chutes 7, a first slider 8 is arranged on the moving assembly, a third connecting plate 9 is arranged at the top of the first slider 8, a third magnetic surface repelling the first magnetic surface is arranged on the third connecting plate 9, and a telescopic assembly is arranged at the bottom of the first slider 8, a stirring rod 10 is arranged at the bottom of the telescopic assembly, a transverse mixing rod 11 is arranged on the stirring rod 10, and a fourth magnetic surface repelling the second magnetic surface is arranged on the top transverse mixing rod 11.
[0031] Its working principle is as follows: First, add the organic matter to be fermented (such as organic wastewater, biomass resources, etc.) and fermentation microorganisms into the interior of the fermentation tank cylinder 1. These microorganisms will utilize the organic matter to produce hydrogen during the subsequent fermentation process, and start the rotating assembly to make it start to rotate. The rotating assembly drives the rotating rod 5 to rotate through mechanical connection, and then drives the connection disk 6 installed at the top of the rotating rod 5 to rotate. A plurality of sliding grooves 7 arrayed on the connection disk 6 are provided with moving components, and these moving components move as the connection disk 6 rotates. When the first slider 8 on the moving component rotates to a position corresponding to the first connection plate 3 on the inner wall of the fermentation tank cylinder 1, a repulsive force is generated between the first magnetic surface (set on the first connection plate 3) and the third magnetic surface (set on the third connection plate 9 at the top of the first slider 8). This repulsive force drives the first slider 8 to move in the sliding groove 7, and then drives the stirring rod 10 and the transverse mixing rod 11 to move in the horizontal direction. This movement enables the stirring assembly to cover a wider area, ensuring the uniform mixing of microorganisms and substrates. While the stirring rod 10 is moving, the transverse mixing rod 11 on the stirring rod 10 not only rotates and stirs, but also generates a repulsive force between the fourth magnetic surface thereon and the second magnetic surface on the second connection plate 4 on the inner wall of the fermentation tank cylinder 1. This repulsive force causes the stirring rod 10 to move up and down under the action of the telescopic assembly, thereby realizing the deep stirring of the materials at the bottom of the fermentation tank cylinder 1. This deep stirring helps to break the material deposition, improve the contact efficiency between microorganisms and substrates, and further promote the production of hydrogen. As the stirring assembly continues to work, the microorganisms and substrates in the fermentation tank remain in a uniformly mixed state, providing favorable conditions for the growth and metabolism of microorganisms. The microorganisms utilize the organic matter for fermentation metabolism, produce hydrogen and release it into the fermentation tank. This device realizes the efficient and uniform stirring of the materials in the fermentation tank, improving the fermentation efficiency and hydrogen production.
[0032] Among them, a feed pipe 12 and a discharge pipe 13 are provided on the fermentation tank cylinder 1. The organic matter enters through the feed pipe 12 and exits through the discharge pipe 13.
[0033] At the same time, an air outlet 14 is provided on the sealing cover 2, and a gas collection pipeline is connected through the air outlet 14 to collect hydrogen.
[0034] An inspection window 15 is provided on the fermentation tank cylinder 1, and the internal situation can be observed through the inspection window 15.
[0035] The width of the first connection plate 3 is greater than the width of the third connection plate 9. Such a setting enables a certain amount of time for all-round stirring when generating the repulsive force for movement.
[0036] At the same time, the width of the second connection plate 4 is greater than the width of the transverse mixing rod 11. Such a setting enables a certain amount of time for all-round stirring when generating the repulsive force for downward movement.
[0037] The moving component includes a fixed shaft 16 disposed inside the chute 7. A first spring 17 and a first slider 8 are sleeved on the fixed shaft 16, and one side of the first slider 8 is connected to the first spring 17.
[0038] When a repulsive force is generated between the first connecting plate 3 and the third connecting plate 9, the first slider 8 drives the stirring rod 10 to squeeze the first spring 17 on the fixed shaft 16, thereby moving left and right.
[0039] The telescopic component includes a hollow cylinder 18 connected to the first slider 8. A second spring 19 is disposed inside the hollow cylinder 18. A piston disk 20 is disposed at the bottom of the second spring 19. A movable rod 21 is disposed at the bottom of the piston disk 20, and the bottom of the movable rod 21 penetrates out of the hollow cylinder 18 and is connected to the stirring rod 10.
[0040] When a repulsive force is generated between the second connecting plate 4 and the transverse mixing rod 11, the stirring rod 10 drives the movable rod 21 to move, and the movable rod 21 drives the piston disk 20 to stretch the second spring 19, thereby moving up and down.
[0041] The rotating component includes a motor 22 disposed at the bottom of the fermentation tank cylinder 1. The output end of the motor 22 is connected to the rotating rod 5. The motor 22 drives the rotating rod 5 to rotate the stirring rod 10, thereby mixing the organic matter.
[0042] The working principle of this utility model is as follows: First, add the organic matter to be fermented (such as organic wastewater, biomass resources, etc.) and fermentation microorganisms into the interior of the fermentation tank cylinder 1. These microorganisms will utilize the organic matter to produce hydrogen during the subsequent fermentation process, and start the rotating assembly to make it start rotating. The rotating assembly drives the rotating rod 5 to rotate through mechanical connection, and then drives the connecting plate 6 installed on the top of the rotating rod 5 to rotate. A plurality of sliding grooves 7 arrayed on the connecting plate 6 are provided with moving components, and these moving components move as the connecting plate 6 rotates. When the first slider 8 on the moving component rotates to a position corresponding to the first connecting plate 3 on the inner wall of the fermentation tank cylinder 1, a repulsive force is generated between the first magnetic surface (set on the first connecting plate 3) and the third magnetic surface (set on the third connecting plate 9 on the top of the first slider 8). This repulsive force drives the first slider 8 to move in the sliding groove 7, and then drives the stirring rod 10 and the horizontal mixing rod 11 to move in the horizontal direction. This movement enables the stirring assembly to cover a wider area and ensures the uniform mixing of microorganisms and substrates. While the stirring rod 10 is moving, the horizontal mixing rod 11 on the stirring rod 10 not only rotates and stirs, but also generates a repulsive force between the fourth magnetic surface thereon and the second magnetic surface on the second connecting plate 4 on the inner wall of the fermentation tank cylinder 1. This repulsive force causes the stirring rod 10 to move up and down under the action of the telescopic assembly, thereby realizing the deep stirring of the materials at the bottom of the fermentation tank cylinder 1. This deep stirring helps to break the material deposition, improve the contact efficiency between microorganisms and substrates, and further promote the production of hydrogen. As the stirring assembly continues to work, the microorganisms and substrates in the fermentation tank remain in a uniform mixing state, providing favorable conditions for the growth and metabolism of microorganisms. The microorganisms use the organic matter for fermentation metabolism, produce hydrogen and release it into the fermentation tank. This device realizes the efficient and uniform stirring of the materials in the fermentation tank, and improves the fermentation efficiency and hydrogen production.
[0043] The above are only the preferred embodiments of this utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of this utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of this utility model.
