Abstract
Description
Technical Field
[0001] This invention belongs to the field of environmental protection equipment technology, specifically a cow manure treatment device. Background Technology
[0002] Cow manure is a dry substance excreted by cattle, whose main components are organic matter such as cellulose, hemicellulose and lignin. After proper fermentation, these organic substances can be transformed into valuable resources. With the booming development of the cattle industry, cow manure pollution has become a major challenge.
[0003] Nowadays, cow dung is mainly fermented into fertilizer and biogas for reuse. Cow dung is mixed with an appropriate amount of water, crop straw and other organic matter to form suitable fermentation raw materials. The mixture is put into a biogas digester, where anaerobic fermentation decomposes the organic matter in the cow dung into biogas and biogas slurry. The biogas produced is used to power gas stoves, generators and other equipment. The biogas slurry is used for farmland irrigation or as organic fertilizer to improve soil fertility.
[0004] Cow manure is produced at a relatively constant rate every day, and it takes a certain amount of time for it to ferment in a biogas digester. This requires multiple biogas digesters to be used in rotation and cow manure to be stored. This not only requires a large construction site but also increases the cost and is not conducive to the operation of farmers.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0030] like Figures 1 to 4As shown in the embodiment of the present invention, a cow manure treatment device includes a fermentation tank 1; a top cover 2 is bolted to the top of the fermentation tank 1; a sealing gasket is provided between the fermentation tank 1 and the top cover 2; a first rotating rod 3 is rotatably installed in the middle of the fermentation tank 1; the top of the first rotating rod 3 rotatably passes through the top cover 2; a rotating sealing ring is provided between the first rotating rod 3 and the top cover 2; a first motor 4 is fixedly connected to the top of the top cover 2; the rotating shaft of the first motor 4 is fixedly connected to the top of the first rotating rod 3; a radial partition plate 5 is fixedly connected to the outer ring of the first rotating rod 3; the bottom surface of the partition plate 5 slides in contact with the inner bottom surface of the fermentation tank 1; the outer periphery of the partition plate 5 slides in contact with the inner periphery of the fermentation tank 1; the partition plate 5 evenly divides the interior of the fermentation tank 1 into multiple fermentation chambers; a feeding structure and a discharging structure are provided on one side of the top of the top cover 2; the feeding structure and the discharging structure correspond to two adjacent fermentation chambers respectively; during operation, cow manure is mixed with an appropriate amount of water and crops. Straw and other organic matter are mixed together to form suitable fermentation raw materials. These materials are then fed into fermentation tank 1 via a feeding structure and sequentially filled into fermentation chambers separated by partition plate 5. After a certain fermentation time, the raw materials in each chamber sequentially form biogas, biogas slurry, and biogas residue. When it is necessary to discharge or add raw materials, the biogas inside fermentation tank 1 is completely discharged before proceeding. After the biogas is discharged, motor 4 is started, which drives rotating rod 3 to rotate partition plate 5, rotating the fully fermented fermentation chamber to the discharge structure. The fermented biogas residue is then discharged from fermentation tank 1 for fertilizer production. Afterward, motor 4 drives partition plate 5 to rotate, causing the discharged fermentation chamber to rotate back to the feeding structure for adding more fermentation raw materials. This achieves continuous fermentation of cow manure, reducing the amount and time required for storage and facilitating its use by farmers.

[0032] like Figure 1 , Figure 2 and Figure 4As shown, the feeding structure includes a feeding port 7; the feeding port 7 is fixedly connected to the top of the top cover 2; a conveying housing 8 is installed on the top of the feeding port 7; a second rotating rod 9 is rotatably installed inside the conveying housing 8; one end of the second rotating rod 9 rotatably passes through the conveying housing 8; a second motor 10 is fixedly connected to the end of the conveying housing 8; the rotating shaft of the second motor 10 is fixedly connected to the end of the second rotating rod 9; a feeding spiral blade 11 is fixedly connected to the outer ring of the second rotating rod 9; the outer ring of the feeding spiral blade 11 slides in contact with the inner wall of the conveying housing 8; the top of the end of the conveying housing 8 away from the feeding port 7... A hopper 12 is fixedly connected to the inside of the conveying shell 8. During operation, when adding fermentation raw materials, the mixed raw materials are poured into the hopper 12. The second motor 10 drives the second rotating rod 9 to rotate, which in turn drives the feeding spiral blade 11 to rotate against the inner wall of the conveying shell 8, pushing the raw materials falling into the conveying shell 8 into the feed inlet 7, and then into the fermentation chamber inside the fermentation tank 1. The feeding spiral blade 11 pushes the raw materials to be conveyed, which not only facilitates the mixing between the raw materials, but also the fit between the feeding spiral blade 11 and the conveying shell 8 effectively prevents biogas leakage inside the fermentation tank 1.
[0033] like Figure 1 , Figure 2 and Figure 4 As shown, a flange gate valve 13 is connected between the discharge end of the conveying shell 8 and the top of the inlet 7; a sealing cover 14 is bolted to the top surface of the hopper 12; during operation, when adding fermentation raw materials, the flange gate valve 13 is opened and the sealing cover 14 is removed, so that the hopper 12, the conveying shell 8 and the inlet 7 are connected; the flange gate valve 13 and the sealing cover 14 further reduce the probability of biogas leakage inside the fermentation tank 1.
[0034] like Figure 1 , Figure 3 , Figure 4 and Figure 7As shown, the discharge structure includes a discharge port 15; the top of the top cover 2 is fixedly connected to the discharge port 15; a first cylinder 16 is slidably installed inside the discharge port 15; a second cylinder 17 is fixedly connected to the bottom of the first cylinder 16; multiple water channels 18 are evenly distributed on the outer ring of the second cylinder 17; a discharge pipe is provided on the side of the top of the first cylinder 16 away from the middle of the fermentation tank 1; a third rotating rod 19 is rotatably installed inside the first cylinder 16 and the second cylinder 17; the top of the third rotating rod 19 rotatably passes through the top of the first cylinder 16; a third motor 20 is fixedly connected to the top of the first cylinder 16; the rotating shaft of the third motor 20 is fixedly connected to the top of the third rotating rod 19; a discharge spiral blade 21 is fixedly connected to the outer ring of the third rotating rod 19; a connecting beam 22 is bolted to the top of the first cylinder 16; a hydraulic cylinder 23 is provided on one side of the fermentation tank 1; The piston rod of the hydraulic cylinder 23 is fixedly connected to the bottom surface of the connecting beam 22. During operation, when the fermentation chamber where the raw materials have fully fermented rotates to the discharge structure, the hydraulic cylinder 23 drives the connecting beam 22 to descend, which in turn drives the first cylinder 16, the second cylinder 17, the third rotating rod 19, and the discharge spiral blade 21 to descend. They enter the interior of the fermentation tank 1 through the discharge port 15, allowing the second cylinder 17 and the discharge spiral blade 21 to insert into the fermentation chamber where the raw materials have fully fermented. The third motor 20 drives the third rotating rod 19 to rotate, which in turn drives the discharge spiral blade 21 to rotate. The discharge spiral blade 21, in conjunction with the second cylinder 17, conveys the biogas residue upwards. At the same time, the water channel 18 on the outer ring of the second cylinder 17 filters out the biogas slurry from the biogas residue, improving the dryness of the biogas residue. Afterwards, the biogas residue is discharged upwards from the fermentation tank 1 along the second cylinder 17, making it easier for workers to remove the biogas residue from the fermentation tank 1 for fertilizer production.
[0035] like Figures 2 to 5 As shown, a circular baffle 24 is snapped onto the inner ring of the top of the fermentation tank 1; the outer ring of the circular baffle 24 is clamped and fixed to the fermentation tank 1 and the top cover 2; the middle part of the circular baffle 24 is rotatably engaged with the outer ring of the first rotating rod 3; multiple ventilation slots 25 are evenly opened on the circular baffle 24; a pair of interfaces 26 are fixedly connected to the circular baffle 24; the bottom of the interfaces 26 penetrates the circular baffle 24; the tops of the two interfaces 26 are respectively connected to the feed inlet 7 and the discharge outlet 15; through the circular baffle 24 and the ventilation slots 25, the probability of biogas slurry splashing inside the fermentation tank 1 when adding raw materials and removing biogas residue is effectively blocked; through the interfaces 26, the two interfaces 26 are respectively connected to the feed inlet 7 and the discharge outlet 15, reducing the probability of raw materials and biogas residue falling onto the top of the circular baffle 24.
[0036] like Figure 3 and Figure 6As shown, a groove 27 is provided on the bottom surface of the fermentation tank 1; the groove 27 corresponds to the discharge structure; a sealing plug 28 is fixedly connected to the bottom end of the third rotating rod 19; the bottom end of the sealing plug 28 can contact the bottom surface of the groove 27; the diameter of the sealing plug 28 is the same as the inner diameter of the discharge port 15; during operation, when the fermentation chamber where the raw material fermentation is complete rotates to the discharge structure, the biogas residue settles inside the fermentation chamber and accumulates in the groove 27. The bottom of the second cylinder 17 and the discharge spiral blade 21 extends into the groove 27, which is conducive to the full discharge of biogas residue; through the sealing plug 28 set at the bottom of the third rotating rod 19, after the biogas residue is discharged, when the discharge structure rises and moves out of the fermentation tank 1, the sealing plug 28 is inserted into the discharge port 15 to seal and block, thereby preventing biogas leakage inside the fermentation tank 1.
[0037] like Figure 3 and Figure 7 As shown, the discharge spiral blade 21 is provided with multiple filter grooves 29 evenly distributed on a section of the second cylinder 17; by providing filter grooves 29, in conjunction with the water passage grooves 18 on the outer ring of the second cylinder 17, the filtration speed of biogas slurry in biogas residue is further improved, thereby improving the dryness of the filter residue.
[0038] like Figure 1 , Figure 2 and Figure 4 As shown, a gas outlet 30 is fixedly connected to one side of the top of the top cover 2; the gas outlet 30 is connected to the interior of the fermentation tank 1; a one-way valve is installed in the middle of the gas outlet 30; the gas outlet 30 is connected to the gas storage tank through the biogas pump; during operation, the biogas pump discharges the biogas inside the fermentation tank 1 in real time through the gas outlet 30 and delivers it to the gas storage tank for storage, thereby facilitating the later utilization of biogas.
[0039] like Figure 2 and Figure 6 As shown, a drainage trough 31 is provided on one side of the bottom surface of the fermentation tank 1; a filter plate is fixedly connected to the top surface of the drainage trough 31; an outlet 32 is fixedly connected to the outer ring of the bottom of the fermentation tank 1, and a valve is installed on the outlet 32; the outlet 32 is connected to the bottom of the drainage trough 31; during operation, the biogas slurry inside the fermentation tank 1 is filtered by the filter plate on the top of the drainage trough 31, and the biogas slurry flows into the drainage trough 31 and is discharged through the outlet 32, making it convenient for workers to use the biogas slurry for irrigation and fertilization of farmland.
[0040] Working principle: Cow dung is mixed with an appropriate amount of water, crop straw and other organic matter to form suitable fermentation raw materials;
[0041] After a certain period of fermentation, the raw materials in each fermentation chamber successively form biogas, biogas slurry, and biogas residue. The biogas pump discharges the biogas inside the fermentation tank 1 in real time through the gas outlet 30 and transports it to the gas storage tank for storage. The biogas slurry inside the fermentation tank 1 is filtered by the filter plate on the top of the drainage trough 31 and flows into the drainage trough 31. The biogas slurry is discharged through the liquid outlet 32, making it convenient for staff to use the biogas slurry for irrigation and fertilization of farmland.
[0042] When biogas residue needs to be removed, after the biogas inside fermentation tank 1 is discharged, motor 4 is started. Motor 4 drives the first rotating rod 3 to rotate, which in turn rotates the partition plate 5, moving the fermentation chamber where the raw materials have been fully fermented to the discharge structure. Hydraulic cylinder 23 drives the connecting beam 22 to descend, which in turn lowers the first cylinder 16, the second cylinder 17, the third rotating rod 19, and the discharge spiral blade 21. The residue enters the interior of fermentation tank 1 through discharge port 15, allowing the second cylinder 17 and the discharge spiral blade 21 to insert into the fermentation chamber where the raw materials have been fully fermented. Motor 20 drives the third rotating rod 19 to rotate, which in turn rotates the discharge spiral blade 21, discharging the residue. The spiral blade 21, in conjunction with the second cylinder 17, conveys the biogas residue upwards. Simultaneously, the water channel 18 on the outer ring of the second cylinder 17 and the filter channel 29 on the discharge spiral blade 21 filter out the biogas slurry from the biogas residue, improving the dryness of the biogas residue. Afterwards, the biogas residue is discharged upwards from the fermentation tank 1 along the second cylinder 17, making it easier for workers to remove the biogas residue inside the fermentation tank 1 for fertilizer production. Then, the hydraulic cylinder 23 pushes the connecting beam 22 to rise, which in turn drives the first cylinder 16, the second cylinder 17, the third rotating rod 19, and the discharge spiral blade 21 to rise. When they are removed from the fermentation tank 1, the sealing plug 28 is inserted into the discharge port 15 to seal and block it.
[0043] When adding fermentation raw materials, open the flange gate valve 13 and remove the sealing cap 14. Pour the mixed raw materials into the hopper 12. The second motor 10 drives the second rotating rod 9 to rotate, which drives the feeding spiral blades 11 to rotate against the inner wall of the conveying shell 8. The raw materials falling into the conveying shell 8 are pushed into the feed inlet 7 and then into the fermentation chamber in the fermentation tank 1. This realizes the continuous fermentation of cow manure, reduces the storage amount and storage time of cow manure, and makes it convenient for farmers to use.
