Description

Technical Field

[0001] This invention relates to the field of manure fermentation technology, specifically to a fermentation device for efficiently converting livestock and poultry manure into organic fertilizer. Background Technology

[0002] With the rapid development of large-scale livestock and poultry farming, the amount of livestock and poultry manure discharged is increasing year by year. Direct discharge or simple dumping not only causes environmental problems such as soil acidification, water eutrophication, and air pollution, but also wastes valuable resources such as nitrogen, phosphorus, potassium, and organic matter in the manure. At the same time, the demand for organic fertilizer in agricultural production is growing. Replacing chemical fertilizer with organic fertilizer is a key measure to improve soil fertility, ensure the quality and safety of agricultural products, and promote the green and sustainable development of agriculture. This provides a broad market space for the resource-based conversion of livestock and poultry manure into organic fertilizer.

[0003] In existing fermentation devices, when fermenting livestock and poultry manure, the manure is usually introduced into the fermentation tank through the feed inlet. The stirring device rotates to mix the manure and microorganisms, so that the microorganisms decompose the manure and improve the fermentation efficiency. However, in the process of large-scale fermentation of livestock and poultry manure, due to the large volume of the fermentation pile, the traditional manual method of adding microorganisms is relatively simple and the dispersion is not uniform enough. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the present invention provides a fermentation device for the efficient conversion of livestock and poultry manure into organic fertilizer, which effectively solves the problem that the traditional manual method of adding microbial inoculants is relatively simple and the dispersion is not uniform.

[0009] Preferably, the feeding assembly includes slide rods, with slide rods slidably mounted on the front and rear of the square box respectively. An elliptical ring is fixedly mounted on the right end of each slide rod, and a pull rod is fixedly mounted on the right end of each elliptical ring. A sealing plate located below the lower port of the drainage pipe is fixedly mounted between the right ends of the two pull rods. Swing rods are fixedly mounted on the front and rear shafts of the impeller respectively. A drive shaft located inside the elliptical ring is fixedly mounted on each swing rod, and a return spring is fixedly mounted on the left end of each slide rod.

[0010] Preferably, an inlet pipe is fixedly installed on the closed plate, a rectangular plate is installed inside the bottom port of the square box, a circular plate is installed inside the bottom port of the inlet pipe, a synchronizing rod is fixedly installed between the rectangular plate and the circular plate, and a first telescopic rod connected to the synchronizing rod is provided on the closed plate.

[0011] Preferably, a water storage cylinder is sleeved on the outside of the feeding pipe and located above the top cover, and a water inlet pipe is fixedly installed on the water storage cylinder.

[0012] Preferably, the partition plate has a rectangular opening in the middle, and inclined plates are provided on the left and right sides of the rectangular opening.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The impeller and swing rod are driven by the feces to rotate, which allows the drive shaft to slide along the inner wall of the elliptical ring. During the reciprocating motion of the slide rod and pull rod, the sealing plate moves, thereby realizing the automatic and uniform dispersion of bacteria to fall into contact with the feces. This achieves automatic operation, which reduces the physical strength of personnel and improves work efficiency.

[0017] 2. The dehydration auger conveys the manure downwards, achieving dry and wet separation of the manure, which is more conducive to the fermentation process. During the rotation of the stirring shaft, multiple magnetic plates rotate, which not only break up the manure but also adsorb the iron slag in the manure, significantly reducing the iron slag content and preventing the components inside the fermentation tank from being worn by iron slag, thus reducing safety hazards.

[0018] 3. Because a large amount of gas is produced during the fermentation of poultry and livestock manure, when the gas pressure inside the fermentation tank is too high, the gas will open the one-way valve and be discharged out through the exhaust pipe, thus maintaining the gas balance inside the fermentation tank and improving safety.

[0033] The following reference Figures 1 to 13 The various embodiments of the present invention will be described in detail. Those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0034] Example 1:

[0035] A high-efficiency fermentation device for converting livestock and poultry manure into organic fertilizer, such as Figure 1 , Figure 2 , Figure 7As shown, the fermentation tank includes a vertically connected fermentation tank 1. A top cover 2 is fixedly installed on the top surface of the fermentation tank 1, and a bottom cover 3 is fixedly installed on the bottom surface. A discharge pipe is fixedly connected to the bottom end of the bottom cover 3, and a valve is installed on the discharge pipe. A feeding pipe 4 is fixedly connected to the top surface of the top cover 2. A dehydration component is installed inside the feeding pipe 4 for dehydrating the manure. A removal component is installed at the lower end of the dehydration component for removing iron slag from the manure. An isolation plate 5 is fixedly installed on the inner wall of the fermentation tank 1, located below the removal component. A conical chamber 6 is fixedly installed on the bottom surface of the isolation plate 5. A square box 7 is fixedly connected to the bottom of the chamber 6. A semi-circular box 8 is fixedly connected to the right side of the square box 7. An impeller 9 is rotatably installed inside the semi-circular box 8. The blades of the impeller 9 extend into the interior of the square box 7. An addition chamber 10 is provided on the outside of the fermentation tank 1. A suitable inoculum is placed inside the addition chamber 10. A drainage pipe 11 is fixedly connected to the bottom of the addition chamber 10. The lower end of the drainage pipe 11 is fixedly connected to the interior of the fermentation tank 1 and is located on the right side of the semi-circular box 8. A feeding component that cooperates with the drainage pipe 11 is provided on the square box 7. The bottom surface of the square box 7 is fixedly connected to the sealing plate 12.

[0036] The feces enter the dehydration unit through the feeding pipe 4 for dehydration treatment. After dehydration, the feces enter the impurity removal unit for impurity removal treatment. After impurity removal, the feces fall into the conical hopper 6 and the square box 7. Then, the feces drive the blades of the impeller 9 to rotate, and the feces fall into the fermentation tank 1 below. During the rotation of the impeller 9, the feeding unit moves and opens the bottom side opening of the drainage pipe 11. Then, the inoculum falls into the lower end of the fermentation tank 1 and mixes with the feces for subsequent fermentation treatment.

[0037] Because the feces and bacteria fall simultaneously, the bacteria are dispersed more evenly, allowing for thorough mixing of the feces and bacteria, reducing manual labor and physical exertion.

[0038] Example 2:

[0039] like Figure 6 , Figure 7As shown, multiple water outlet holes 13 are evenly arranged on the outer wall of the lower half of the feeding pipe 4. The dewatering component includes a dewatering auger 14. The dewatering auger 14 is rotatably installed inside the feeding pipe 4. The blades of the dewatering auger 14 slide in contact with the inner wall of the feeding pipe 4. A U-shaped frame 15 is fixedly installed at the bottom end of the top cover 2. A positioning shaft 16, which is coaxially fixedly connected to the dewatering auger 14, is rotatably installed on the U-shaped frame 15. A pressing plate 17 that slides up and down is sleeved on the positioning shaft 16. The pressing plate 17 is located below the bottom port of the feeding pipe 4. Two guide shafts 18 are fixedly installed on the bottom surface of the pressing plate 17. The bottom ends of the two guide shafts 18 slide through the U-shaped frame 15. A compression spring 19 is sleeved on the two guide shafts 18. One end of the compression spring 19 is fixedly connected to the bottom surface of the compression plate 17, and the other end is fixedly connected to the top surface of the U-shaped frame 15. Under normal conditions, due to the action of the compression spring 19, the pressing plate 17 is sealed inside the bottom port of the feeding pipe 4.

[0040] The dehydration auger 14 carries the manure downwards, where it is blocked and squeezed by the extrusion plate 17. The water in the manure is discharged out through the water outlet 13, thus achieving the dehydration treatment of the manure. As the dehydration auger 14 continuously transports the manure, it pushes the extrusion plate 17 downwards. The two extrusion springs 19 gradually compress the manure, which falls into the impurity removal component through the gap between the extrusion plate 17 and the bottom of the feeding pipe 4. Through the cooperation between the extrusion plate 17 and the extrusion springs 19, the dry and wet separation of the manure can be achieved, which is convenient for subsequent fermentation treatment.

[0041] Example 3:

[0042] like Figure 2 , Figure 6 , Figure 7 , Figure 12 As shown, the impurity removal assembly includes a stirring drum 20. Two symmetrical vertical plates 21 are fixedly installed on the top surface of the isolation plate 5. The stirring drum 20 is fixedly installed between the top ends of the two vertical plates 21. A certain gap is reserved between the bottom end of the stirring drum 20 and the top surface of the isolation plate 5. A sealing cover 22 is fixedly installed at the rear end of the stirring drum 20, and a sealing cover 22 is installed internally at the front end. Built-in rods are fixedly installed on the front and rear inner walls of the stirring drum 20, respectively. A stirring shaft 23 is rotatably connected between the two built-in rods. The outer surface of the stirring shaft 23 is uniformly fixed with... Multiple stirring tubes are fixedly installed, and a magnetic plate 24 is fixedly installed inside each stirring tube. The magnetic plate 24 is a magnet. A protective cylinder 25 is fixedly installed on the bottom surface of the top cover 2. The protective cylinder 25 is sleeved on the outside of the U-shaped frame 15. The bottom end of the protective cylinder 25 has a conical structure and is fixedly connected to the stirring cylinder 20. The positioning shaft 16 extends through the protective cylinder 25 into the interior of the stirring cylinder 20. A first bevel gear is fixedly installed coaxially in the middle of the stirring shaft 23, and a second bevel gear that meshes with the first bevel gear is fixedly installed coaxially at the bottom end of the positioning shaft 16.

[0043] After dehydration, the feces fall into the protective cylinder 25 and then into the mixing cylinder 20. During the rotation of the mixing shaft 23, multiple magnetic plates 24 rotate, which not only breaks up the feces but also adsorbs the iron slag in the feces, thus greatly reducing the iron slag content in the feces, preventing the components inside the fermentation tank 1 from being worn by iron slag, and reducing safety hazards.

[0044] During the rotation of the stirring shaft 23, the first bevel gear meshes with the second bevel gear, which in turn rotates the positioning shaft 16 and the dehydration auger 14, continuing to transport the feces.

[0045] Example 4:

[0046] like Figure 9 , Figure 10 , Figure 11 , Figure 13 As shown, the feeding assembly includes a slide bar 26. Slide bars 26 are slidably mounted on the front and rear sides of the square box 7, respectively. An elliptical ring 27 is fixedly mounted on the right end of each slide bar 26, and a pull rod 28 is fixedly mounted on the right end of each elliptical ring 27. Long grooves are provided on the front and rear surfaces of the square box 7. A slider is fixedly connected to the left end of each pull rod 28, and the slider slides left and right within the corresponding long groove. A sealing plate 29 is fixedly mounted between the right ends of two pull rods 28. The top surface of the sealing plate 29 slides in contact with the bottom surface of the drainage pipe 11. Positioning blocks are fixedly mounted on the front and rear sides of the square box 7, respectively. The two positioning blocks are located at... On both sides of the semicircular box 8, the front and rear shafts of the impeller 9 pass through the semicircular box 8 and are rotatably connected to the positioning blocks. On the outer side of each positioning block, a swing rod 30 is rotatably installed and fixedly connected to the shaft of the impeller 9. The other end of each swing rod 30 is fixedly installed with a drive shaft 31. The drive shaft 31 is slidably installed inside the corresponding elliptical ring 27. The left end of each slide rod 26 is fixedly installed with a return spring 32. The other end of each return spring 32 is fixedly connected to the left end of the square box 7. Under normal conditions, due to the force of the two return springs 32, the two sealing plates 29 seal the bottom port of the drainage pipe 11.

[0047] like Figure 7 , Figure 10As shown, an inlet pipe 33 is fixedly installed on the sealing plate 12. The sealing plate 12 divides the inlet pipe 33 into upper and lower parts, and the diameter of the inlet pipe 33 is larger than the diameter of the drainage pipe 11. The inlet pipe 33 and the drainage pipe 11 are directly opposite each other, which facilitates the falling of the inoculum. A rectangular plate 34 is installed in the bottom port of the square box 7, and a circular plate 35 is installed in the bottom port of the inlet pipe 33. The tops of the rectangular plate 34 and the circular plate 35 are conical structures. A synchronization rod 36 is fixedly installed between the rectangular plate 34 and the circular plate 35. A first telescopic rod 37 is fixed on the sealing plate 12. The lower telescopic end of the first telescopic rod 37 is fixedly connected to the synchronization rod 36. The first telescopic rod 37 is an electric telescopic rod and is connected to the controller through a wire. The controller is connected to the power supply through a wire.

[0048] The controller starts the first telescopic rod 37 to move upward with the synchronous rod 36, the top surface of the rectangular plate 34 is flush with the bottom surface of the square box 7, and the top surface of the circular plate 35 is flush with the top surface of the inlet pipe 33.

[0049] When the feces drive the impeller 9 to rotate, it will drive the two swing rods 30 to rotate. The two drive shafts 31 slide along the inner wall of the elliptical ring 27 and drive the two slide rods 26 and the pull rods 28 to move back and forth. The two pull rods 28 simultaneously drive the sealing plate 29 to move back and forth. Then the two return springs 32 continuously compress and stretch.

[0050] When the sealing plate 29 is no longer sealing the bottom of the drainage pipe 11, the bacteria will fall into the inlet pipe 33. Since the top of the rectangular plate 34 and the circular plate 35 are conical slopes, the bacteria will slide down the slope of the circular plate 35, and the feces will slide down the slope of the rectangular plate 34, so that the feces and bacteria are dispersed into the lower end of the fermentation tank 1, achieving full mixing of feces and bacteria. It can also control the falling of bacteria according to the amount of feces, improving the degree of automation, reducing the physical strength of personnel and improving work efficiency.

[0051] like Figure 1 As shown, a water storage cylinder 38 is sleeved on the outside of the feeding pipe 4 and located above the top cover 2. The upper and lower ends of the water storage cylinder 38 are closed structures, and a water inlet pipe 39 is fixedly connected to the water storage cylinder 38.

[0052] After the feces are squeezed, the water is discharged out through the outlet hole 13 into the water storage tank 38, and then discharged into a suitable external container through the water inlet pipe 39, thus reducing environmental pollution.

[0053] like Figure 2 , Figure 7 , Figure 9As shown, a rectangular opening 40 is provided in the middle of the isolation plate 5, and the discharge port 42 is provided vertically corresponding to the rectangular opening 40. Inclined plates 41 are fixedly provided on the left and right sides of the rectangular opening 40 to prevent the feces from overflowing. An arc plate 43 is slidably connected to the outer surface of the mixing drum 20. The inclined plate 41 will not interfere with the movement of the arc plate 43. A positioning block is fixedly installed on the top surface of the isolation plate 5, and a fixing block is fixedly installed on the outer side of the upper end of the arc plate 43. The bottom end of the second telescopic rod 44 is rotatably connected to the positioning block, and the telescopic end is rotatably connected to the fixing block. The second telescopic rod 44 is an electric telescopic rod and is connected to the controller through a wire.

[0054] After the iron slag in the feces is removed, the controller starts the second telescopic rod 44 to gradually extend, the arc plate 43 slides along the outside of the mixing drum 20, and at the same time the second telescopic rod 44 swings to open the discharge port 42. Then the feces fall into the conical hopper 6 through the discharge port 42 and the rectangular opening 40, thus realizing automatic control.

[0055] like Figure 1 , Figure 12 As shown, a stirring motor 45 is fixedly installed on the outer side of the rear closed cover 22. The rotating shaft of the stirring motor 45 is coaxially and fixedly connected to the stirring shaft 23. The stirring motor 45 is connected to the controller through a wire. Maintenance ports are provided at the front and rear of the fermentation tank 1, and each maintenance port is corresponding to the closed cover 22 on the same side. Maintenance covers 46 are threaded into the two maintenance ports to facilitate subsequent maintenance and cleaning.

[0056] Example 5:

[0057] like Figure 2 , Figure 5 As shown, an exhaust pipe 47 is fixedly installed through the sealing plate 12. The upper end of the exhaust pipe 47 extends to the outside of the fermentation tank 1. A one-way valve that can only exhaust air is installed inside the exhaust pipe 47. A positioning rod located below the sealing plate 12 is fixedly installed on the inner wall of the fermentation tank 1. A vertical mixing shaft 48 is rotatably installed at the bottom end of the positioning rod. A mixing frame 49 is fixedly installed on the outer side of the mixing shaft 48. The mixing frame 49 has multiple rectangular holes to facilitate the passage of manure. A mixing motor 50 is fixedly installed on the top surface of the sealing plate 12. The mixing motor 50 is connected to the controller through wires. The pulley group 51 includes two pulleys and a belt. A pulley located below the sealing plate 12 is coaxially fixedly installed on the shaft of the mixing motor 50. Another pulley is coaxially fixedly connected to the top end of the mixing shaft 48. A first belt is connected between the two pulleys.

[0058] When the feces and bacteria fall into the fermentation tank 1 below, the controller starts the mixing motor 50 to rotate, and the pulley group 51 drives the mixing shaft 48 and the stirring rack 49 to rotate, so as to achieve full mixing of feces and bacteria.

[0059] After mixing is complete, the controller starts the first telescopic rod 37 to move upward with the synchronous rod 36, the rectangular plate 34 closes the bottom port of the square box 7 and the circular plate 35 closes the bottom port of the inlet pipe 33, and the feces and bacteria are fermented.

[0060] During the fermentation of poultry and livestock manure, a large amount of gas is generated. When the gas pressure inside the fermentation tank 1 is too high, the gas will open the one-way valve and be discharged out through the exhaust pipe 47, thus maintaining the gas balance inside the fermentation tank 1 and improving safety. The fermented organic fertilizer can be discharged out through the discharge pipe for further processing.
