[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figure 1-4 This invention provides a drum-type fermentation device for livestock and poultry farm manure, comprising:

[0031] Fermentation tank 1 is rotatably connected to two support plates 2. Fermentation tank 1 has a material inlet 3, a feeding inlet 4, and a flow outlet 5. The material inlet 3 is equipped with a first sealing cover 6, the feeding inlet 4 is equipped with a second sealing cover 7, and the flow outlet 5 is equipped with a valve 8. Fermentation tank 1 is driven by a first motor 9. A mixing and stirring mechanism is installed inside fermentation tank 1. The mixing and stirring mechanism is driven by a third motor 10, which is located outside fermentation tank 1. A first rotating shaft 11 is rotatably connected inside fermentation tank 1 and extends out of fermentation tank 1. The first rotating shaft 11 has a flow channel 13 and several first through holes 14. The flow channel 13 connects to a water adding mechanism and a ventilation mechanism. The first rotating shaft 11 is driven by a second motor 12, which is installed on the support plate 2. The support plate 2 is fixedly connected to a base plate 15, and the first motor 9 is fixedly connected to the base plate 15.

[0032] Livestock and poultry manure is fermented in fermentation tank 1. The manure is added to fermentation tank 1 through material inlet 3. Feeding inlet 4 is used to add fermentation agent. Flow outlet 5 is used to discharge gas or excess water generated in fermentation tank 1. First sealing cover 6 is used to seal material inlet 3, and second sealing cover 7 is used to seal feeding inlet 4. First motor 9 drives fermentation tank 1 to rotate, and third motor 10 drives mixing and stirring mechanism to move. Mixing and stirring mechanism is used to mix livestock and poultry manure and fermentation agent. When adding water, the water is injected through flow channel 13 of first rotating shaft 11 and flows out through first through hole 14. Aeration mechanism introduces gas into fermentation tank 1 to regulate the temperature inside fermentation tank 1. The gas flows into fermentation tank through flow channel 13 and first through hole 14. Second motor 12 drives first rotating shaft 11 to rotate, making it more convenient to clean fermentation tank 1.

[0033] The scheme is further optimized. The mixing and stirring mechanism includes two second rotating shafts 16, which are rotatably connected inside the fermentation tank 1. The two second rotating shafts 16 are diagonally arranged inside the fermentation tank 1. A spiral blade 17 is fixedly connected to the second rotating shaft 16. The spiral blade 17 is less than half the length of the fermentation tank 1. The second rotating shaft 16 extends out of the fermentation tank 1. The second rotating shaft 16 is fixedly connected to the output end of the third motor 10. A reinforcing rod 18 is fixedly connected inside the fermentation tank 1. The reinforcing rod 18 is inclined. A first sleeve 19 is fixedly connected to the reinforcing rod 18. The end of the second rotating shaft 16 away from the third motor 10 extends into the first sleeve 19. The second rotating shaft 16 is rotatably arranged inside the first sleeve 19. The third motor 10 is fixedly connected to the fermentation tank 1 through a connecting plate.

[0034] The second rotating shaft 16 is positioned diagonally within the fermentation tank 1. The third motor 10 drives the second rotating shaft 16 to rotate, which in turn drives the spiral blades 17 to rotate. Since the two second rotating shafts 16 are positioned diagonally, when one of the second rotating shafts 16 drives the spiral blades 17 to rotate, the spiral blades 17 will push the livestock and poultry manure to the other side of the fermentation tank 1. When the fermentation tank 1 rotates, the livestock and poultry manure will move to the position of the other second rotating shaft 16 and, driven by the other spiral blades 17, move to one side of the fermentation tank 1. As the fermentation tank 1 rotates, the livestock and poultry manure is repeatedly turned over within the fermentation tank 1, thereby achieving thorough mixing. This facilitates the mixing of manure and fermentation agents and also promotes the turning of manure during the fermentation process. The reinforcing rod 18 is inclined within the fermentation tank 1, and the inclined reinforcing rod 18 can avoid the material inlet 3 and the flow outlet 5. The first sleeve 19 is used to support the second rotating shaft 16.

[0035] The scheme is further optimized. Two main shafts 20 are fixedly connected to both ends of the fermenter 1. The two main shafts 20 are rotatably connected to the support plate 2. The first rotating shaft 11 passes through the main shaft 20 and is rotatably connected inside the main shaft 20. A second sleeve 21 is fixedly connected to the reinforcing rod 18. The first rotating shaft 11 passes through the second sleeve 21 and is rotatably set inside the second sleeve 21.

[0036] Fermentation tank 1 is rotatably connected to support plate 2 via main shaft 20. First rotating shaft 11 passes through main shaft 20, and second sleeve 21 is used to support first rotating shaft 11.

[0037] The scheme is further optimized. The water filling mechanism includes a water inlet pipe 22, which is connected to a water source. A first solenoid valve 23 and a first check valve 24 are installed on the water inlet pipe 22. Two limiting plates 25 are fixedly connected to the first rotating shaft 11. A fixing ring 26 is sleeved on the first rotating shaft 11 and is located between the two limiting plates 25. The first rotating shaft 11 is rotatably set within the fixing ring 26. An annular groove 27 is opened in the fixing ring 26. A connecting hole 28 is opened on the first rotating shaft 11 and is connected to the flow channel 13. The connecting hole 28 is located within the annular groove 27. The water inlet pipe 22 is fixedly connected to the fixing ring 26 and is connected to the annular groove 27. The first check valve 24 is located on the end of the water inlet pipe 22 near the fixing ring 26.

[0038] The first solenoid valve 23 is used to control the water flow in the inlet pipe 22. The first one-way valve 24 can prevent water backflow and also prevent gas from entering the inlet pipe 22. The annular groove 27 in the fixing ring 26 facilitates the connection between the inlet pipe 22 and the flow channel 13. When water needs to be added to the fermentation tank 1, water flows into the annular groove 27 through the inlet pipe 22. Since the connecting hole 28 is in the annular groove 27, water can flow into the flow channel 13.

[0039] The scheme is further optimized. The ventilation mechanism includes an air inlet pipe 29, which is fixedly connected to a fixed ring 26. The air inlet pipe 29 is connected to an annular groove 27. A second solenoid valve 30 and a second one-way valve 31 are installed on the air inlet pipe 29. The second one-way valve 31 is located on the end of the air inlet pipe 29 near the fixed ring 26. A hot air blower 51 is connected to the end of the air inlet pipe 29 away from the fixed ring. A pressure gauge is installed on the fermenter 1.

[0040] The second solenoid valve 30 is used to control the air inlet pipe 29. The second one-way valve 31 prevents gas and water from flowing into the air inlet pipe 29. When gas needs to be introduced into the fermenter 1, the temperature of the hot air blower 51 is set according to the temperature. The gas generated by the hot air blower 51 enters the annular groove 27 through the air inlet pipe 29, and then enters the flow channel 13 through the annular groove 27, and finally enters the fermenter 1. The pressure gauge can observe the gas pressure in the fermenter 1 to prevent the gas pressure from being too high.

[0041] The scheme is further optimized by providing an anti-blocking mechanism on the through hole. The anti-blocking mechanism includes a plug 32 and a connecting pipe 33. The connecting pipe 33 is fixedly connected to the first through hole 14 and communicates with the first through hole 14. A horizontal plate 34 is fixedly connected inside the connecting pipe 33. The horizontal plate 34 has a through hole and several second through holes 35. A connecting rod 36 is inserted through the through hole. The connecting rod 36 is fixedly connected to the plug 32 and elastically connected to the horizontal plate 34. A baffle 37 is fixedly connected to the end of the connecting rod 36 away from the plug 32. A first spring 38 is sleeved on the connecting rod 36. One end of the first spring 38 abuts against the horizontal plate 34, and the other end of the first spring 38 abuts against the baffle 37.

[0042] Without the flow of water or gas, the plug 32 will contact the connecting pipe 33 under the action of the first spring 38, blocking the connecting pipe 33 and preventing livestock and poultry manure from entering the flow channel 13. When there is gas or water in the flow channel 13, the gas or water will push the plug 32 up through the second through hole 35. At this time, the baffle 37 will compress the first spring 38. When the gas and water flow stops, the plug 32 will return to its original position under the action of the first spring 38.

[0043] The scheme is further optimized. A mesh plate 47 is fixedly connected inside the fermentation tank. The mesh plate 47 is located at the flow port 5. A drain pipe 48 is fixedly connected to the flow port 5. A valve 8 is installed on the drain pipe 48. A second spring 49 is fixedly connected inside the fermentation tank 1. A V-shaped plate 50 is fixedly connected to the second spring 49. The opening of the V-shaped plate 50 faces the first rotating shaft 11.

[0044] The mesh plate 47 can prevent livestock and poultry manure from clogging the flow port 5. The flow port 5 facilitates the discharge of excess liquid or gas. When discharging excess liquid, the fermentation tank 1 is rotated so that the flow port 5 faces downward. When discharging excess gas, the flow port 5 faces upward. During the fermentation process of livestock and poultry manure, it may stick to the wall of the fermentation tank 1. When the fermentation tank 1 is rotated, the livestock and poultry manure will move with the rotation. At this time, the second spring 49, which is no longer under pressure, will spring up, causing the manure on the V-shaped plate 50 to detach from the side wall. The V-shaped plate 50 is V-shaped, which can prevent the manure from sticking to the wall of the fermentation tank 1.

[0045] Further optimization of the scheme: several crushing blades 39 are fixedly connected to the first rotating shaft 11, the crushing blades 39 are located inside the fermentation tank 1, a third solenoid valve 40 is installed on the first rotating shaft 11, the third solenoid valve 40 is used to control the flow channel 13, the third solenoid valve 40 is located outside the fermentation tank 1, and a temperature sensor is fixedly connected inside the fermentation tank 1.

[0046] During the turning process of livestock and poultry manure, the first rotating shaft 11 rotates, and the crushing blade 39 can crush the manure to prevent it from clumping. The third solenoid valve 40 is used to control the flow channel 13 to prevent gas or water from flowing out. The temperature sensor is used to measure the temperature inside the fermentation tank 1.

[0047] In a further optimized design, a first pulley 41 is fixedly connected to the main shaft 20, and a second pulley 42 is fixedly connected to the first motor 9. The first pulley 41 and the second pulley 42 are connected by a belt 43. A first gear 44 is fixedly connected to the first rotating shaft 11, and a second gear 45 is fixedly connected to the output end of the second motor 12. The first gear 44 and the second gear 45 mesh. A mounting plate 46 is fixedly connected to the support plate 2, and the second motor 12 is fixedly connected to the mounting plate 46.

[0048] The first motor 9 drives the second pulley 42 to rotate, the second pulley 42 drives the first pulley 41 to rotate via the belt 43, the first pulley 41 drives the main shaft 20 to rotate, the second motor 12 drives the second gear 45 to rotate, and the second gear 45 drives the first gear 44 to rotate.

[0049] A method for drum fermentation of manure in livestock and poultry farms includes the following steps:

[0050] Step 1: Rotate fermentation tank 1 using the first motor 9 so that the material inlet 3 of fermentation tank 1 faces upward. Open the first sealing cover 6 and add livestock and poultry manure into fermentation tank 1 through the material inlet 3. Then, fasten the first sealing cover 6 to the material inlet 3.

[0051] Step 2: Rotate the fermentation tank 1 so that the feeding port 4 faces upward, open the second sealing cover 7, add the fermentation agent into the fermentation tank 1, and then fasten the second sealing cover 7 to the feeding port 4;

[0052] Step 3: Start the first motor 9, which drives the fermentation tank 1 to rotate. At the same time, start the third motor 10, which drives the second rotating shaft 16 to rotate. The second rotating shaft 16 drives the spiral blades 17 to rotate. When one of the second rotating shafts 16 drives the spiral blades 17 to rotate, the spiral blades 17 will push the livestock and poultry manure to the other side of the fermentation tank 1. When the fermentation tank 1 rotates, the livestock and poultry manure will move to the position of the other second rotating shaft 16 and move to one side of the fermentation tank 1 under the drive of the other spiral blades 17. As the fermentation tank 1 rotates, the livestock and poultry manure will be repeatedly turned over in the fermentation tank 1, thereby achieving the purpose of thorough mixing.

[0053] Step 4: Close the first one-way valve 24, open the second one-way valve 31, start the ventilation mechanism, and the gas generated by the hot air blower 51 enters the annular groove 27 through the air inlet pipe 29, then enters the flow channel 13 through the annular groove 27, and finally enters the fermentation tank 1. After the gas is added, water is added to the fermentation tank 1 through the water adding mechanism. Close the second one-way valve 31, open the first one-way valve 24, and the water flows into the annular groove 27 through the water inlet pipe 22. Since the connecting hole 28 is in the annular groove 27, the water can flow into the flow channel 13 and finally enter the fermentation tank 1.

[0054] Step 5: Ferment the livestock and poultry manure. During the fermentation process, the fermentation tank 1 can be rotated as needed, and the livestock and poultry manure can be stirred by the mixing and stirring mechanism. During the turning process of the livestock and poultry manure, the first rotating shaft 11 rotates, and the crushing blade 39 can crush the manure to prevent the livestock and poultry manure from clumping.

[0055] Step 6: After fermentation is complete, rotate fermentation tank 1 so that material outlet 3 faces downwards, making it easier to pour out the fermented livestock and poultry manure.
