Description

Technical Field

[0001] The present invention relates to the technical field of bacterial fermentation, and in particular to a high-efficiency methanogenic bacteria device and process used as biomass energy. Background Art

[0002] Methanogens, a species of archaea, can convert organic acids and alcohols produced by biomass fermentation into methane under anaerobic conditions. They possess unique metabolic pathways, are sensitive to their environment, and thrive under favorable conditions. They efficiently contribute to biomass energy conversion and play a key role in green energy supply.

[0003] In the biomass energy sector, methanogen fermentation is an important approach to producing methane. However, current methanogen fermentation equipment faces numerous challenges. The inoculation and mixing of bacterial strains and materials often rely on manual labor, which impacts operator skill and fatigue. This makes batch consistency difficult to achieve when scaling up production, leading to unstable methanogen fermentation results. Even the slightest deviation in the mixing ratio can inhibit methanogen activity, significantly reducing methane production and energy conversion efficiency.

[0004] The material mixing method is also not ideal. Mixing large amounts of materials at once results in inadequate contact, poor mixing uniformity, and inadequate material utilization. While adding materials incrementally and mixing them works better, it is cumbersome, labor-intensive, and time-consuming, failing to meet the demands of large-scale industrial production. Frequent opening and closing of the equipment can easily introduce air, disrupting the anaerobic environment. Methanogenic fermentation requires a strictly anaerobic environment, and manual operation under anaerobic conditions is difficult, inconvenient, and prone to air introduction, which can breed bacteria. These bacteria compete with the methanogens for nutrients, interfering with fermentation and reducing product purity and yield.

[0005] Based on this, a high-efficiency methanogen device and process for biomass energy are proposed. Summary of the Invention

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] See also Figures 1-6 , the present invention provides a technical solution: A high-efficiency methanogen device used as a biomass energy source includes a shell 1 and a control panel 2. The control panel 2 can be used to adjust the fermentation temperature and whether the internal structure is in operation. A sealed door 3 is connected to the shell 1. The sealed door 3 structure can facilitate the placement of a mixing chamber 10 and is sealed with the shell 1 structure. A contact piece 17 is connected to the inside of the shell 1. A mixing chamber 10 is provided in the shell 1. A docking seat 19 is connected to the outside of the mixing chamber 10. When the mixing chamber 10 is placed inside the device, the docking seat 19 can abut against the contact piece 17, thereby connecting the circuit for controlling the operation of the motor 11. The inside of the mixing chamber 10 is connected to the motor 11, and the output end of the motor 11 is connected to a stirring frame 34. When the motor 11 is running, it can drive the stirring frame 34 connected to the output end to rotate, thereby stirring and mixing the bacterial species and materials in the mixing chamber 10, thereby improving the fermentation efficiency. A fixing frame 6 is connected to the inside of the shell 1, and a feed pipe 2 18 is connected to the fixing frame 6. A button 2 33 is connected to the fixing frame 6. The button 2 33 structure is arranged at the lower end of the fixing frame 6, and the upper end of the feed pipe 2 18 is connected to the shell 1. Therefore, when connecting the material conveying pipeline, it is only necessary to connect it at the upper end of the shell 1. A slide rail 2 7 is slidably connected to the inside of the shell 1. The slide rail 2 7 structure is horizontally arranged. A sliding column 8 is slidably connected to the slide rail 2 7. The sliding column 8 is connected to the feed pipe 1 9. The feed pipe 1 9 is vertically connected to one side of the sliding column 8. A button 1 27 is connected to one side of the feed pipe 1 9. The button 1 27 can control whether the feed pipe 1 9 is opened or not. A bending plate 4 is connected to one side of the shell 1. The sliding column 8 and the slide rail 2 7 structure are arranged between the shell 1 and the bending plate 4. The bending plate 4 is connected to a control mechanism for controlling the feed pipe 1 9 and the feed pipe 2 18 to mix anaerobic fermentation materials in proportion.

[0021] Specifically, such as Figure 3 and Figure 4 As shown, a slide rail 1 5 is connected to the inner side of the shell 1, and the slide rail 1 5 is vertically arranged. A sliding block 22 is slidably connected to the slide rail 1 5, and the sliding block 22 is fixedly connected to one side of the slide rail 2 7. The slide rail 2 7 is horizontally arranged. By setting the sliding block 22, the slide rail 2 7 can slide stably on one side of the slide rail 1 5.

[0022] Specifically, such as Figure 3 、 Figure 4 and Figure 5 As shown, the control mechanism includes a slide rod 13, a bending groove 12 is provided on the bending plate 4, and the bending groove 12 has an L-shaped structure. The slide rod 13 is slidably connected to the bending groove 12, and a telescopic cylinder 15 is rotatably connected to the slide rod 13. The telescopic cylinder 15 is rotatably connected to the bending plate 4. One end of the slide rod 13 is rotatably connected to the slide post 8. When the slide rod 13 slides along the bending groove 12, it can synchronously drive the slide post 8 connected at one end to move, that is, the movement trajectory of one end of the slide post 8 is L-shaped; The upper end of the second slide rail 7 is connected to a pressing ring 23 via a spring 24. The pressing ring 23 is arranged directly below the second button 33. The length of the spring 24 is related to the pressing time of the pressing ring 23 on the second button 33. That is, the longer the spring 24 is, the earlier it supports the pressing ring 23 to contact the second button 33. At this time, the longer the opening time of the second feeding pipe 18 is, the higher the occupancy rate of the strains added to the preparation bin 10 is. One side of the slide rail 27 is connected to a rotating piece 25, which is rotatably connected to a connecting bar 30 through a docking pipe 29. One end of the connecting bar 30 is rotatably connected to a connecting bar 2 31. One side of the feed pipe 19 is connected to a rotating piece 26, one end of the connecting bar 2 31 is rotatably connected to the rotating piece 26, and one end of the connecting bar 2 31 is connected to a cam 32. The docking pipe 29 is rotatably connected to the inner side of the rotating piece 25, and the docking pipe 29 structure is sleeved on the outer side of the feed pipe 2 18. The cam 32 structure is arranged on one side of the button 127.

[0023] Specifically, such as Figure 4 As shown, the telescopic end of the telescopic cylinder 15 is connected to a push tube 14, which is sleeved on the slide rod 13. By setting the push tube 14, the wear of the transmission between the telescopic cylinder 15 and the slide rod 13 is reduced, and the stability of the slide rod 13 sliding along the bending groove 12 is improved.

[0024] Specifically, such as Figure 4 and Figure 5 As shown, the telescopic cylinder 15 is connected to a cylinder sleeve 16, and the cylinder sleeve 16 is connected to a deflection rod 28. The deflection rod 28 is rotatably connected to the bending plate 4. The stability of the structural connection of the telescopic cylinder 15 is improved by providing the cylinder sleeve 16. During the telescopic process of the telescopic cylinder 15, the deflection rod 28 will rotate.

[0025] Specifically, such as Figure 4 As shown, one end of the sliding column 8 is rotatably connected to a sleeve 21, and the sleeve 21 is rotatably connected to the sliding column 8. By providing the sleeve 21, the wear between the structures when the sliding rod 13 pushes the sliding column 8 to move is reduced, making the structure more stable when the sliding column 8 moves.

[0026] Specifically, such as Figure 4 and Figure 5 As shown, the upper end of the slide rail 2 7 is connected to a limiting rod 20, and the pressing ring 23 and the spring 24 are sleeved on the limiting rod 20. The limiting rod 20 is connected to the fixing frame 6. The pressing ring 23 is limited by setting the limiting rod 20 structure, so that the pressing ring 23 can be stably raised and lowered along the limiting rod 20, thereby improving the stability of the pressing ring 23 pressing the button 2 33 structure.

[0027] In summary, the present embodiment provides a high-efficiency methanogenic bacteria device and process used as biomass energy. When methanogenic bacteria fermentation is required, the feed pipe 1 9 and the feed pipe 2 18 on the device can be connected to the corresponding material conveying pipeline, and then the sealed door 3 is opened, and the preparation bin 10 is placed inside the device. At this time, the docking seat 19 connected to one side of the preparation bin 10 and the contact piece 17 are docked with each other. At this time, the circuit controlling the rotation of the motor 11 is connected, and then the sealed door 3 is closed to ensure that the fermentation environment is not affected by the outside world.

[0028] Then, the telescopic cylinder 15 is controlled to operate through the control panel 2. The operating state of the telescopic cylinder 15 is intermittent reciprocating telescopic operation, that is, there is a certain downtime between one continuous reciprocating telescopic operation. The downtime is the operating time of the motor 11, that is, when the telescopic cylinder 15 is extended and retracted, the motor 11 stops running, and when the telescopic cylinder 15 stops extending and retracting, the motor 11 starts running.

[0029] When the telescopic cylinder 15 is extended, the slide rod 13 is pushed along the bending groove 12 through the push tube 14, and the slide column 8 connected to one end of the slide rod 13 moves synchronously. In the initial stage, the slide column 8 rises in height, thereby pushing the slide rail 2 7 connected to the outside of the slide column 8 to rise in height. At this time, the slide rail 2 7 structure slides along the slide rail 1 5, and the pressing ring 23 connected to the upper end of the slide rail 2 7 through the spring 24 moves up to press the button 2 33 structure. When the button 2 33 structure is pressed, the slide rail 2 7 continues to move up. At this time, the spring 24 structure is compressed, and the button 2 33 structure can control the feed pipe 2 18 to add bacteria to the mixing bin 10.

[0030] As the telescopic cylinder 15 continues to extend, the slide rod 13 enters the horizontal part of the bending groove 12. At this time, the slide rod 13 structure begins to move horizontally, driving the slide column 8 to move horizontally, while the slide rail 2 7 structure stops rising in height. The button 2 33 remains pressed, the spring 24 remains compressed, and the slide column 8 structure begins to slide along the slide rail 2 7. The feed pipe 1 9 moves away from the feed pipe 2 18. At this time, due to the limitation of the connecting bar 1 30 and the connecting bar 2 31, the cam 32 structure connected to one end of the connecting bar 2 31 begins to rotate. When the cam 32 rotates above the rotating piece 2 26, it can rely on the cam 32 structure to abut against the button 1 27, so that the button 1 27 structure is pressed. The button 1 27 structure can control the feed pipe 1 9 to add the material for fermentation into the mixing bin 10. Since the feed pipe 1 9 is in a horizontal moving state during the adding process, the material can be evenly added to the mixing bin 10.

[0031] When the telescopic cylinder 15 is extended and retracted, the amount of material added to the mixing bin 10 by the feed pipe 19 and the feed pipe 2 18 is different, thereby achieving mixing requirements of different proportions, and a single structure can only perform fermentation mixing of one proportion. After the telescopic cylinder 15 is extended to its longest state, it begins to contract. At this time, the feed pipe 19 stops running first, and then the feed pipe 2 18 stops running. When the telescopic cylinder 15 contracts to its maximum state, the structure for mixing the fermentation material in the shell 1 is reset, the telescopic cylinder 15 stops running, and the motor 11 starts running, and drives the stirring rack 34 to mix and stir the material added to the mixing bin 10 until the telescopic cylinder 15 is extended again. After the fermentation material in the mixing bin 10 is added, the temperature control structure inside the device controls the fermentation temperature of the fungus material, so that the fungus can ferment at a suitable temperature.

[0032] This device has significant innovation and outstanding advantages. When mixing bacterial strains and materials, manual operation is abandoned. Instead, the control mechanism composed of the slide rod 13, the telescopic cylinder 15, etc. is relied on. The telescopic cylinder 15 is intermittently reciprocated to accurately control the opening and closing time of each feed pipe, so as to achieve precise proportional mixing and solve the problems of low precision and large batch differences in manual mixing. In terms of mixing method, during mixing, the feed pipe 9 moves horizontally to add materials so that they are evenly distributed in the mixing bin 10, and then the motor 11 drives the stirring rack 34 to stir, which greatly improves the mixing effect. In terms of anaerobic environment protection, the fully enclosed shell 1 and the sealed door 3 are isolated from the outside air. The entire process of mixing, mixing and fermentation does not require manual operation in an anaerobic environment, avoiding the introduction of air and miscellaneous bacteria, and creating a stable anaerobic fermentation environment for methanogens. Through the overall innovative design, the background technical difficulties are effectively overcome, the efficiency and quality of biomass energy fermentation are greatly improved, and the development of the industry is strongly promoted.
