Description

Technical Field

[0001] The present invention relates to the technical field of microbial fermentation, and particularly to a device for collecting and fermenting livestock and poultry waste. Background Art

[0002] Biogas fermentation is a reaction process carried out by various microorganisms under anaerobic conditions. Biogas fermentation can not only treat organic waste and produce renewable energy, but also has multiple greenhouse gas emission reduction benefits, and has been widely promoted and applied. Therefore, after collecting livestock and poultry waste, biogas is produced through anaerobic fermentation reaction of microorganisms for utilization.

[0003] In the prior art, the microbial anaerobic fermentation device applied to livestock and poultry waste directly stacks a large amount of livestock and poultry excrement and other organic waste inside the anaerobic fermentation reactor, and then the fermentation reaction can be carried out. However, since a large amount of biogas residue is generated during fermentation, and there are differences in the fermentation efficiency of the materials on the surface and hidden at the bottom layer, the generation speed of biogas residue is inconsistent. After some materials are fermented to form biogas residue, it is impossible to specifically discharge this part of biogas residue, and the discharge difficulty is high. As a result, the overall fermentation efficiency inside the fermenter is low, and the biogas production efficiency of the livestock and poultry waste put in the same batch in the early stage and the later stage is also different.

[0026] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0027] Please refer to Figures 1 to 6, the present invention provides the following technical solution: A livestock and poultry waste collection and fermentation device, comprising a fermentation device body. The fermentation device body includes an anaerobic fermentation reactor 1, a circulation mechanism 2, a pushing component 3, and an independent fermentation bin 4. An extraction channel 9 is integrally formed on the bottom side of the anaerobic fermentation reactor 1, and an insertion channel 8 is integrally formed on the top side of the anaerobic fermentation reactor 1. The circulation mechanism 2 is welded to the other ends of the extraction channel 9 and the insertion channel 8. A biogas residue collection box 5 is welded to one side of the bottom of the circulation mechanism 2. A plurality of independent fermentation bins 4 are filled inside the anaerobic fermentation reactor 1, and adjacent independent fermentation bins 4 are stacked and pressed against each other. The pushing component 3 is inserted into the side of the circulation mechanism 2, and a bottom layer pulling plate 29 is welded to the bottom of the pushing component 3. The bottom layer pulling plate 29 is embedded inside the extraction channel 9. A top layer push rod 31 is welded to the top of the pushing component 3, and the end of the top layer push rod 31 is embedded inside the circulation mechanism 2. This livestock and poultry waste collection and fermentation device is used to generate biogas, and this biogas fermentation realizes the anaerobic fermentation process through the participation of microorganisms, mainly involving four stages. These stages work together to convert the complex organic substances in livestock and poultry waste into methane and carbon dioxide. These stages are realized through reactions in the anaerobic fermentation reactor 1 part of the present invention. This reaction process includes the action of hydrolysis and fermentative bacteria groups, the activities of hydrogen-producing and acetic acid-producing bacteria, the participation of obligately anaerobic methanogenic bacteria groups, and the homoacetogenic stage. In the above stages, the fermentation materials are filled into the independent fermentation bin 4 in batches, and then the independent fermentation bin 4 filled with the fermentation materials is pushed into the anaerobic fermentation reactor 1 through the pushing component 3 to carry out the anaerobic fermentation reaction. The independent fermentation bin 4 at the bottom layer is regularly pulled out to realize the process of discharging the remaining biogas residue after the fermentation reaction and refilling the fermentation materials.

[0028] In this embodiment, a partition net 13 is inserted inside the anaerobic fermentation reactor 1. A fermentation reaction cavity 16 is formed inside the partition net 13. A support ring 14 is welded to the outer side of the top of the partition net 13. A plurality of through holes 15 are formed on the surface of the support plate 18. Columns 12 are welded to the bottom of the anaerobic fermentation reactor 1. The side of the support ring 14 and the bottom edge of the oxygen fermentation reactor are welded to the inner wall of the anaerobic fermentation reactor 1 as a whole. The bottom end of the partition net 13 is higher than the top of the extraction channel 9. Each independent fermentation bin 4 is stacked inside the fermentation reaction cavity 16. A spray pipe 10 is inserted into the top of the anaerobic fermentation reactor 1. A fermentation gas discharge pipe 11 is inserted into the top side of the anaerobic fermentation reactor 1. A gap is provided between the side of the partition net 13 and the inner wall of the anaerobic fermentation reactor 1. The inside of the fermentation reaction cavity 16 is partially communicated with the fermentation gas discharge pipe 11 after passing through the partition net 13 and the through holes 15 in sequence. By means of the cooperation of a plurality of independent fermentation bins 4 stacked inside and the circulation mechanism 2, each independent fermentation bin 4 can be loaded with livestock and poultry waste fermentation materials from the top end of the anaerobic fermentation reactor 1 and placed. Quantitative fermentation materials can be put in at different times. Different batches of fermentation materials are stacked from top to bottom according to the putting time, so that the anaerobic fermentation time of the fermentation materials in different areas is the same, improving the uniformity of fermentation.

[0029] Specifically, a plurality of independent fermentation bins 4 are stacked in the fermentation reaction cavity 16 inside the partition net 13 for fermentation reaction. The biogas generated after anaerobic fermentation directly passes through the air holes 20 on the enclosure plate 33 inside the independent fermentation bin 4 and then passes through the partition net 13 and enters the gap between the partition net 13 and the inner wall of the anaerobic fermentation reactor 1. In the fermentation state, the bottom of the anaerobic fermentation reactor 1 is in a closed state, and the end of the extraction access is also blocked by the sealing plate 32 at the discharge port 19. Therefore, the biogas inside the anaerobic fermentation reactor 1 can only flow towards the top. After passing through the through holes 15 on the support ring 14, it finally discharges towards the outside through the fermentation gas discharge pipe 11.

[0030] In this embodiment, a first electric telescopic rod 17 is installed at the inner bottom end of the circulation mechanism 2. The top of the first electric telescopic rod 17 is welded with a support plate 18. A bottom plate 7 is welded to the bottom side of the biogas residue collection box 5. A plug-in sleeve 6 is provided at the top side of the circulation mechanism 2. A cover plate is installed at the top of the circulation mechanism 2. The support plate 18 is in an overall circular structure, and the edge of the support plate 18 is attached to the inner wall of the circulation mechanism 2. The bottom of the first electric telescopic rod 17 is fixed to the surface of the bottom plate 7 with screws. A discharge port 19 is provided at the end of the extraction channel 9.

[0031] Specifically, after each independent fermentation tank 4 is drawn out from the inside of the extraction channel 9 by the pushing component 3 and the remaining biogas residue part after anaerobic fermentation inside it is discharged, it can be pushed again to the bottom position of the circulation mechanism 2. At this time, the first electric telescopic rod 17 is started, and the pallet 18 can be pushed upward by the extension of the first electric telescopic rod 17. Finally, the independent fermentation tank 4 is pushed towards the top by the upward movement of the pallet 18 until it is pushed to be flush with the insertion channel 8. Then, the cover plate at the top of the circulation mechanism 2 can be opened, and new fermentation materials can be put into the inside of the independent fermentation tank 4. Finally, with the help of the pushing component 3 again, the filled independent fermentation tank 4 can be pushed back into the anaerobic fermentation reactor 1 and stacked at the topmost position to carry out anaerobic fermentation treatment again.

[0032] In this embodiment, the pushing component 3 includes a second electric telescopic rod 27 and a translation plate 25. A push plate 26 is integrally formed in the middle of the translation plate 25. The ends of the bottom layer pulling plate 29 and the top layer push rod 31 are welded to the surface of the translation plate 25 as a whole. A conical block 30 is welded to the end of the bottom layer pulling plate 29. One end of the second electric telescopic rod 27 is welded with a fixed block 28, and the fixed block 28 is partially welded to the surface of the circulation mechanism 2. A sealing plate 32 is welded to the surface of the bottom layer pulling plate 29, and the sealing plate 32 is used to block the end of the extraction channel 9. Through the pushing component 3, the independent fermentation tank 4 at the bottommost part can be regularly drawn out from the inside of the anaerobic fermentation reactor 1. Therefore, the fermentation materials put in at different times can discharge the biogas residue after a fixed fermentation time, making the material fermentation more uniform and the biogas residue discharge more efficient and thorough.

[0033] Specifically, when the second electric telescopic rod 27 is started to contract, the bottom layer pulling plate 29 can be partially inserted into the anaerobic fermentation reactor 1 along the extraction channel 9 and finally dock with the bottommost part of the independent fermentation tank 4. At this time, the second electric telescopic rod 27 can be controlled to extend, and the independent fermentation tank 4 can be drawn out until it is completely drawn out from the discharge port 19. At this time, the bottom of the base 22 of the independent fermentation tank 4 loses the block, and the remaining biogas residue part inside the independent fermentation tank 4 can directly fall into the biogas residue collection box 5 through the hole 23. After the biogas residue is discharged, the independent fermentation tank 4 can be pushed back to the bottom position of the circulation mechanism 2 again.

[0034] In this embodiment, the independent fermentation tank 4 includes a surrounding plate 33 and a base 22. The base 22 is welded to the bottom of the surrounding plate 33. A hole 23 is formed in the middle of the base 22. A concave plate 24 is provided on one side of the base 22. A plurality of ventilation holes 20 are formed above the side edge of the surface of the surrounding plate 33. Elastic clamping blocks 21 are inserted at the bottom of the surrounding plate 33. The independent fermentation tank 4 is docked and clamped with the conical block 30 through the elastic clamping blocks 21 inside the extraction channel 9. The independent fermentation tank 4 is pressed on the support plate 18 through the base 22 at the bottom. Both the inside of the anaerobic fermentation reactor 1 and the inside of the circulation mechanism 2 are in a closed state, ensuring an effective anaerobic fermentation space for microorganisms. Moreover, the pushing assembly 3 can directly pull out and automatically discharge the digested residue part at the bottom layer without damaging the anaerobic fermentation cavity, reducing the consumption of human resources.

[0035] The bottom of each independent fermentation tank 4 cooperates with the conical block 30 on the bottom layer pull plate 29 through the elastic clamping blocks 21 to ensure that the independent fermentation tank 4 can be pulled out after the second electric telescopic rod 27 extends. The process of the first electric telescopic rod 17 jacking up the independent fermentation tank 4 towards the top will not be interfered by the horizontally connected elastic clamping blocks 21. When the independent fermentation tank 4 moves into the insertion channel 8, the pushing assembly 3 will directly press the top layer push rod 31 against the side of the surrounding plate 33 after contraction, achieving the purpose of pushing the independent fermentation tank 4 into the anaerobic fermentation reactor 1.

[0036] The foregoing shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.

[0037] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
