Description

[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. It has been widely promoted and applied. Therefore, after livestock and poultry waste is collected, biogas is produced through anaerobic fermentation of microorganisms for utilization.

[0003] In the prior art, the microbial anaerobic fermentation device applied to livestock and poultry waste directly piles a large amount of livestock and poultry excrement and other organic waste into the interior of the anaerobic fermentation reactor and then performs fermentation reaction treatment. However, since a large amount of biogas residue will be produced during fermentation and there is a difference in the fermentation efficiency of the surface material and the material hidden in the bottom layer, the biogas residue production rate is inconsistent. After some materials are fermented to form biogas residue, it is impossible to discharge this part of the biogas residue in a targeted manner, and the discharge is difficult, which leads to low overall fermentation efficiency inside the fermenter.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] See also Figures 1 to 6The present invention provides the following technical solutions: a livestock and poultry waste collection and fermentation device, comprising a fermentation device body, the fermentation device body comprising an anaerobic fermentation reactor 1, a circulation mechanism 2, a pushing component 3 and an independent fermentation bin 4, the bottom side of the anaerobic fermentation reactor 1 is integrally formed with an extraction channel 9, the top side of the anaerobic fermentation reactor 1 is integrally formed with an insertion channel 8, the circulation mechanism 2 is welded to the other end of the extraction channel 9 and the insertion channel 8, a sludge collection box 5 is welded to one side of the bottom of the circulation mechanism 2, the interior of the anaerobic fermentation reactor 1 is filled with a plurality of independent fermentation bins 4, and adjacent independent fermentation bins 4 are stacked and pressed against each other, the side of the circulation mechanism 2 is plugged with a pushing component 3, and the bottom of the pushing component 3 is welded with a bottom pull plate 29, the bottom pull plate 29 is embedded in the interior of the extraction channel 9, the top of the pushing component 3 is welded with a top push rod 31, and the end of the top push rod 31 is embedded in the interior of the circulation mechanism 2. The livestock and poultry waste collection and fermentation device is used to produce biogas, and the biogas fermentation realizes the anaerobic fermentation process through the participation of microorganisms, which mainly involves four stages, which work together to convert the complex organic matter in the livestock and poultry waste into methane and carbon dioxide. These stages are realized by reacting in part of the anaerobic fermentation reactor 1 in the present invention, and the reaction process includes the action of hydrolysis and fermentation bacteria, the activity of hydrogen-producing and acetogenic bacteria, the participation of the specialized anaerobic methanogenic bacteria, and the homoacetic acid production stage. In the above-mentioned stages, the fermentation materials are filled into the interior of the independent fermentation bin 4 in batches, and then the independent fermentation bin 4 filled with the fermentation materials is pushed into the interior of the anaerobic fermentation reactor 1 by the pushing component 3 to carry out the anaerobic fermentation reaction, and the independent fermentation bin 4 at the bottom is pulled out regularly 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 13 is inserted into the interior of the anaerobic fermentation reactor 1, and a fermentation reaction cavity 16 is opened inside the partition 13. A support ring 14 is welded to the outer side of the top of the partition 13, and a plurality of through holes 15 are opened on the surface of the support plate 18. A column 12 is welded to the bottom of the anaerobic fermentation reactor 1. The side of the support ring 14 and the bottom edge of the anaerobic fermentation reactor are welded to the inner wall of the anaerobic fermentation reactor 1 as a whole, and the bottom end of the partition 13 is higher than the top position of the extraction channel 9. Each independent fermentation bin 4 is accumulated inside the fermentation reaction cavity 16. A spray pipe 10 is inserted at the top of the anaerobic fermentation reactor 1, and a fermentation gas exhaust pipe 11 is inserted at the top of the side of the anaerobic fermentation reactor 1. A gap is set between the side of the partition 13 and the inner wall of the anaerobic fermentation reactor 1, and the interior of the fermentation reaction cavity 16 is connected to part of the fermentation gas exhaust pipe 11 after passing through the partition 13 and the through holes 15 in sequence. By cooperating with the circulation mechanism 2 through the internal stacking of multiple independent fermentation bins 4, each independent fermentation bin 4 can be loaded with livestock waste fermentation materials from the top of the anaerobic fermentation reactor 1 and placed, and a certain amount of fermentation materials can be added at different times. Different batches of fermentation materials can be stacked from top to bottom in sequence according to the time of addition, so that the fermentation materials in different areas have the same time for anaerobic fermentation, thereby improving the uniformity of fermentation.

[0029] Specifically, a plurality of independent fermentation bins 4 are stacked in a fermentation reaction cavity 16 on the inner side of a partition 13 for fermentation reaction. The biogas generated after anaerobic fermentation directly passes through the air holes 20 on the enclosure 33 from the inside of the independent fermentation bin 4, and passes through the partition 13 to enter the gap between the partition 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 through which the gas is drawn out also partially blocks the discharge port 19 through a sealing plate 32. Therefore, the biogas inside the anaerobic fermentation reactor 1 can only flow toward the top, pass through the through hole 15 on the support ring 14, and finally be discharged to the outside from 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, a support plate 18 is welded to the top of the first electric telescopic rod 17, a bottom plate 7 is welded to the bottom of the side of the sludge collection box 5, a plug-in sleeve 6 is provided at the top of the side of the circulation mechanism 2, a cover plate is installed on the top of the circulation mechanism 2, the support plate 18 is an overall circular structure, and the edge of the support plate 18 is in contact with 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, and an outlet 19 is provided at the end of the extraction channel 9.

[0031] Specifically, after each independent fermentation bin 4 is extracted from the extraction channel 9 by the pushing component 3, and the remaining sludge after anaerobic fermentation is completed is discharged, it can be pushed to the bottom position of the circulation mechanism 2 again. At this time, the first electric telescopic rod 17 is started, and the support plate 18 can be pushed upward by the extension of the first electric telescopic rod 17. The independent fermentation bin 4 is finally pushed toward the top by the upward movement of the support plate 18 until it is pushed to be flush with the insertion channel 8. The cover plate on the top of the circulation mechanism 2 can be opened, and new fermentation materials can be put into the independent fermentation bin 4. Finally, the filled independent fermentation bin 4 can be pushed back into the anaerobic fermentation reactor 1 with the help of the pushing component 3 again, and piled at the top position for anaerobic fermentation again.

[0032] In this embodiment, the push assembly 3 includes a second electric telescopic rod 27 and a translation plate 25, the middle of the translation plate 25 is integrally formed with a push plate 26, the ends of the bottom pull plate 29 and the top push rod 31 are welded to the surface of the translation plate 25 as a whole, the end of the bottom pull plate 29 is welded with a cone block 30, 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 position of the circulation mechanism 2, and the surface of the bottom pull plate 29 is welded with a sealing plate 32, and the sealing plate 32 is used to block the end of the extraction channel 9. The push assembly 3 can be used to pull out the independent fermentation bin 4 at the bottom from the inside of the anaerobic fermentation reactor 1 at a fixed time, so that the fermentation materials put in at different times can discharge the sludge after a fixed fermentation time, so that the material fermentation is more uniform and the sludge discharge is more efficient and thorough.

[0033] Specifically, by starting the second electric telescopic rod 27 to retract, the bottom pull plate 29 can be inserted along the extraction channel 9 toward the interior of the anaerobic fermentation reactor 1, and will eventually dock with the bottom independent fermentation bin 4. At this time, the second electric telescopic rod 27 can be controlled to extend, and the independent fermentation bin 4 can be pulled out until it is completely pulled out from the discharge port 19. At this time, the bottom of the base 22 of the independent fermentation bin 4 loses its obstruction, and the remaining sludge inside the independent fermentation bin 4 can be directly dropped into the sludge collection box 5 through the hole 23. After the discharge of the sludge is completed, the independent fermentation bin 4 can be pushed back to the bottom position of the circulation mechanism 2 again.

[0034] In this embodiment, the independent fermentation bin 4 includes a panel 33 and a base 22, the base 22 is welded to the bottom of the panel 33, a hole 23 is provided in the middle of the base 22, an inner concave plate 24 is provided on one side of the base 22, a plurality of air holes 20 are provided above the side edge of the surface of the panel 33, an elastic block 21 is inserted at the bottom of the panel 33, the independent fermentation bin 4 is docked and engaged with the cone block 30 part through the elastic block 21 inside the extraction channel 9, and the independent fermentation bin 4 is pressed on the support plate 18 through the base 22 at the bottom. The interior of the anaerobic fermentation reactor 1 and the interior of the circulation mechanism 2 are both in a closed state, ensuring that an effective anaerobic fermentation space is provided for the microorganisms, and the pushing component 3 can directly pull out the bottom layer of the fermented sludge and automatically discharge it without destroying the anaerobic fermentation cavity, reducing the consumption of human resources.

[0035] The bottom of each independent fermentation bin 4 cooperates with the cone block 30 on the bottom pull plate 29 through the elastic block 21 to ensure that the independent fermentation bin 4 can be pulled out after the second electric telescopic rod 27 is extended, and the process of the first electric telescopic rod 17 pushing the independent fermentation bin 4 toward the top will not be interfered by the horizontally connected elastic block 21. When the independent fermentation bin 4 moves to the inside of the insertion channel 8, the pushing assembly 3 at this time will directly push the top push rod 31 against the side of the enclosure 33 after contraction, so as to achieve the purpose of pushing the independent fermentation bin 4 into the anaerobic fermentation reactor 1.

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 the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
