Description

Technical Field

[0001] This invention relates to the field of agricultural waste resource utilization technology, and in particular to a fermentation device for the harmless treatment of chicken manure in ginseng chicken farms. Background Technology

[0002] In ginseng cultivation, chicken manure organic fertilizer, after being treated with harmless fermentation, can effectively improve the soil and optimize the quality of ginseng roots. Aerobic fermentation is the mainstream process for harmless treatment of chicken manure, relying on the synergistic effect of stirring and aeration to create a sufficiently oxygenated and uniformly stable reaction environment for aerobic microorganisms. Currently, most chicken manure fermentation devices on the market are single-chamber structures, with the entire fermentation process completed in a single closed tank, which has many technical shortcomings in practical applications.

[0003] Single-chamber fermenters only have a single-shaft agitator at the center of the tank, and the mixing and shearing range is limited by the blade diameter. Materials in the surrounding areas, such as the tank walls and bottom, are far from the mixing center and experience significantly reduced shear and drag forces. Their flow rate is much lower than at the center, resulting in prolonged low-speed sliding or even stagnation, creating a non-uniform force field with a strong center and weak periphery, leading to poor material mixing uniformity. The stagnant material at the edges and corners undergoes delayed fermentation, ultimately resulting in inconsistent maturity of organic fertilizers from the same batch. Chicken manure contains a large amount of sticky components and fibrous materials. The unidirectional compression and kneading action of the single-shaft agitator easily causes fine particles to agglomerate and form dense clumps. The porosity inside these clumps drops sharply, preventing oxygen penetration and creating a heterogeneous structure with an oxygen-deficient exterior and an oxygen-deficient interior. This makes it difficult for aerobic microorganisms to decompose the internal organic matter, reducing the effective fermentation volume of the tank, decreasing discharge flowability, and increasing discharge resistance. Meanwhile, existing aeration devices are mostly located at the bottom of the tank or inside the stirring shaft. When gas is supplied, the gas rises along the path of least resistance, forming an air passage. A large amount of air escapes directly, resulting in insufficient oxygen supply to the surrounding materials. Materials with high moisture content will exacerbate this problem, causing a situation where hyperaerobic and anoxic zones coexist in the tank, leading to an imbalance in the aerobic fermentation process. Summary of the Invention

[0004] Given that the existing single-chamber structure of chicken manure fermentation tanks has problems such as uneven mixing, material clumping, and imbalance of aeration and oxygen supply, resulting in inconsistent fermentation maturity and poor fermentation effect, a fermentation device for harmless treatment of chicken manure in ginseng chicken farms is proposed.

[0005] The purpose is to divide the tank into multiple chambers axially, reduce the rotational resistance of the stirring mechanism, reduce the gas movement resistance, and install fixed cylinders and guide plates inside the chambers. When the guide plates rotate with the stirring mechanism, they increase the vertical tumbling of the material, improve the loosening effect between the materials, and ensure that the gas and the material are in uniform and sufficient contact.

[0006] The technical solution of this invention is a fermentation device for the harmless treatment of chicken manure in a ginseng chicken farm, comprising a tank body. Multiple partitions are axially and equally spaced within the tank body. Multiple discharge ports are provided on the partitions. An electric discharge component is installed within each discharge port, controlling the opening and closing of the discharge port. A rotating shaft is axially rotatable within the tank body. The rotating shaft has a hollow structure and is movably inserted through the partitions. An exhaust hole communicating with a storage chamber is provided on the rotating shaft. A fixed cylinder is fixedly connected to the tank body above the partitions. A stirring component is also fixedly connected to the rotating shaft above the partitions. An aeration component is provided between the lower end of the fixed cylinder and the tank body. Multiple guide plates are provided between the upper end of the fixed cylinder and the tank body. The guide plates are rotatably connected to the rotating shaft. The guide plates have a bent structure and include a guide surface inclined above the fixed cylinder. One end of the guide surface has a scraping surface extending to the space between the fixed cylinder and the inner wall of the tank body.

[0007] Furthermore, the electric discharge component includes a baffle that fits with the discharge port, one end of the baffle is rotatably connected to the bottom of the partition, and an electric push rod is connected between the baffle and the partition.

[0008] Furthermore, a conical flow guide is fixedly connected to the top surface of the partition, and the rotating shaft is rotatably sealed to the flow guide; the stirring component includes a stirring rod one fixedly connected to the rotating shaft, the stirring rod one being disposed inside the fixed cylinder, and a stirring rod two fixedly connected below the stirring rod one, the stirring rod two having a bent structure, and the stirring rod two being adapted to the flow guide.

[0009] Furthermore, a fixed ring is fixedly connected to the upper end of the flow guide, and a rotating ring is sleeved on the outside of the fixed ring. The rotating ring is fixedly connected to the outer wall of the rotating shaft, and multiple sealing rings are provided between the rotating ring and the fixed ring.

[0010] Furthermore, the aeration element includes multiple concentrically arranged annular pipes, with multiple aeration heads fixed on the annular pipes, and an air supply pipe is provided on the outside of the tank body, with the air supply pipe and the annular pipes being sealed and connected.

[0011] Furthermore, the rotating shaft is provided with multiple planetary gear sets. The sun gear of the planetary gear set is fixedly connected to the outer wall of the rotating shaft. The planet gears and the ring gear of the planetary gear set are rotatably connected to the corresponding partition plates. The ring gear and the guide plate are connected by a connecting rod.

[0012] Furthermore, multiple rotating rods are fixedly connected to the outer wall of the rotating shaft, and a fixed frame is fixedly connected to the other end of the rotating rod. A scraper is vertically slidably connected inside the fixed frame, and the lower end of the scraper passes over the top surface of the guide plate when the rotating shaft rotates.

[0013] Furthermore, a flow divider ring is fixedly connected to the inner wall of the upper end of the fixed cylinder, and multiple fixed rods are fixedly connected to the top surface of the flow divider ring. The multiple fixed rods are arranged in a ring-shaped wave pattern, and a comb rod is fixedly connected to the rotating rod. The comb rod passes through the fixed rod when it rotates with the rotating shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The baffle vertically divides the inside of the tank into multiple independent storage chambers, avoiding the problem of excessive material accumulation and uneven mixing in a single-chamber structure. The fixed cylinder and the guide plate work together to force the material to be guided to the circumferential area of ​​the tank during interlayer transfer. Together with the agitator, it forms a circulation path of "central agitation → peripheral fall → re-entering the center", which effectively expands the range of action of the agitator. Multi-directional agitation and tumbling prevents material from clumping and allows gas and material to fully contact each other, improving the fermentation effect of chicken manure.

[0015] 2. As the material falls along the diversion ring, large pieces are intercepted by the fixed rod. As the comb rod rotates with the shaft, it passes through the fixed rod and continuously shears and breaks up the material clumps, further preventing material agglomeration and ensuring the uniformity of the fermentation process.

Detailed Implementation

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Example 1, referring to Figures 1-6 This invention provides a first embodiment of a fermentation device for the harmless treatment of chicken manure in a ginseng chicken farm. The device includes a tank 1 with multiple partitions 2 spaced axially at equal intervals inside the tank 1. Multiple discharge ports 3 are provided on the partitions 2, and an electric discharge component 4 is installed within each discharge port 3 to control the opening and closing of the discharge ports 3. Specifically, the partitions 2 have a disc-shaped structure, with their outer edges sealed and fixed to the inner wall of the tank 1. The multiple partitions 2 vertically divide the interior of the tank 1 into multiple storage chambers of the same size. Each storage chamber is used for graded fermentation of chicken manure. The electric discharge component 4 controls the opening and closing of the discharge ports 3, thereby achieving the step-by-step descent of material between the storage chambers.

[0020] A rotating shaft 5 is axially rotatable inside the tank body 1. The rotating shaft 5 has a hollow structure and is movably installed through the partition 2. An exhaust port 8 communicating with the storage chamber is opened on the rotating shaft 5. A fixed cylinder 6 is fixedly connected to the tank body 1 above the partition 2. An agitator 7, connected and fixed to the rotating shaft 5, is also installed above the partition 2. An aeration element 12 is installed between the lower end of the fixed cylinder 6 and the tank body 1. Specifically, the upper end of the rotating shaft 5 extends out from the top of the tank body 1 and connects to the drive motor (…). Figure 1 The transmission connection is provided, and the lower end is rotatably supported at the bottom of the tank body 1. The rotating shaft 5 drives the stirring component 7 to rotate, while the aeration component 12 aerates the material storage chamber. The stirring component 7 loosens and turns the material. After the aerated gas comes into full contact with the material, it enters the nearest exhaust hole 8 and is discharged outward through the upper port of the rotating shaft 5.

[0021] Multiple guide plates 14 are provided above the fixed cylinder 6 and between it and the tank body 1. The guide plates 14 are rotatably connected to the rotating shaft 5. The guide plates 14 have a bent structure and include a guide surface 141 inclined above the fixed cylinder 6. One end of the guide surface 141 is provided with a shoveling surface 142 extending to the inner wall between the fixed cylinder 6 and the tank body 1. Specifically, the fixed cylinder 6 divides the storage chamber into an inner area and an outer area. When the rotating shaft 5 drives the agitator 7 to rotate, the shoveling surface 142 of the guide plate 14 is located in the outer area. When rotating, the material in the outer area is transferred to the guide surface 141 and then slides down from the guide surface 141 to the inner area, thereby causing the material to be axially turned. The guide plates 14 and the agitator 7 cooperate to turn the material in multiple directions, avoiding the material from being squeezed and agglomerated due to single radial agitation.

[0022] Through the above technical solutions, the partition 2 divides the material into multiple storage chambers, changing the problems of heavy material accumulation, high stirring resistance, and insufficient aeration in the traditional integrated fermentation tank 1, and significantly reducing the energy consumption of the equipment. The guide plate 14 and the stirring component 7 work together to realize multi-dimensional turning of the material, avoiding the situation of material squeezing and clumping and incomplete local fermentation. The aeration and exhaust structures work together to optimize the fermentation environment and effectively improve the quality of harmless treatment of chicken manure. The fermented chicken manure has high organic matter content and meets the harmlessness standard, and can be directly used as high-quality organic fertilizer for ginseng planting, which is suitable for the fertilizer needs of ginseng breeding and planting.

[0023] Understandably, an inspection port is provided on the side wall of the tank body 1 corresponding to the storage cavity, and an inspection window is provided outside the inspection port. One end of the inspection window is assembled with the outer wall of the tank body 1 by a hinge structure, and the inspection window can be sealed and locked to the outer wall of the tank body 1.

[0024] Reference Figure 3 The electric discharge component 4 includes a baffle 41 that fits with the discharge port 3. One end of the baffle 41 is rotatably connected to the bottom of the partition 2. An electric push rod 42 is connected between the baffle 41 and the partition 2.

[0025] Specifically, when the electric push rod 42 retracts, the baffle 41 flips downward around the hinge point, opening the discharge port 3, and the material falls from the upper storage chamber into the lower storage chamber under gravity; when the electric push rod 42 extends, the baffle 41 flips upward and closes the discharge port 3, allowing the material to ferment independently in each storage chamber. The electric push rod 42 can be an electric lead screw push rod or an electro-hydraulic push rod, and its extension and retraction are automatically controlled by the PLC controller according to a preset timing sequence.

[0026] Reference Figure 3A conical guide shroud 9 is fixedly connected to the top surface of the partition 2, and the rotating shaft 5 is rotatably connected to the guide shroud 9 in a sealed manner. Specifically, the guide shroud 9 is used to guide the material to flow to the multiple outlets 3 at the edge of the partition 2, so as to avoid the material from accumulating in the central area of ​​the partition 2, and to prevent the material from stagnating in the dead corner of the center of the tank 1.

[0027] The stirring component 7 includes a stirring rod 71 fixedly connected to the rotating shaft 5. The stirring rod 71 is disposed inside the fixed cylinder 6. A stirring rod 72 is fixedly connected below the stirring rod 71. The stirring rod 72 has a bent structure and is adapted to the guide shroud 9. Specifically, there is a gap between the lower end of the stirring rod 72 and the conical surface of the guide shroud 9 and the top surface of the partition 2. The stirring rods 71 ​​and 72 work together to scrape and stir the material in the storage chamber. At the same time, the horizontal part of the outer end of the stirring rod 72 conveys the material at the bottom of the storage chamber to the area between the fixed cylinder 6 and the inner wall of the tank 1, forming a multi-angle tumbling of the material in cooperation with the guide plate 14.

[0028] Reference Figure 4 A fixed ring 10 is fixedly connected to the upper end of the flow guide shroud 9. A rotating ring 11 is sleeved on the outside of the fixed ring 10. The rotating ring 11 is fixedly connected to the outer wall of the rotating shaft 5. Multiple sealing rings are provided between the rotating ring 11 and the fixed ring 10. Specifically, the cooperation of the fixed ring 10, the rotating ring 11 and the sealing rings forms a sealed rotating connection between the rotating shaft 5 and the flow guide shroud 9, preventing the material in the storage chamber from leaking along the axial direction of the rotating shaft 5.

[0029] Reference Figure 1 , Figure 2 The aeration element 12 includes multiple concentric annular pipes, with multiple aeration heads fixed on the annular pipes. An air supply pipe 13 is provided on the outside of the tank body 1, and the air supply pipe 13 is sealed and connected to the annular pipes.

[0030] Specifically, one end of the air supply pipe 13 is connected to an external air supply source (such as a blower or air compressor). Multiple branch pipes are fixedly connected to the air supply pipe 13, and the branch pipes are fixedly inserted into the tank body 1 and sealed and connected to the corresponding annular pipe. A flow regulating valve and a pressure gauge can be installed on the air supply pipe 13 for adjusting and monitoring the air supply.

[0031] Reference Figure 5Multiple planetary gear sets 15 are mounted on the rotating shaft 5. The sun gear of each planetary gear set 15 is fixedly connected to the outer wall of the rotating shaft 5. The planetary gears and ring gears of each planetary gear set 15 are rotatably connected to the corresponding partition plates 2. A connecting rod 16 connects the ring gear and the guide plate 14. Specifically, when the rotating shaft 5 rotates, the sun gear drives the planetary gears to rotate, which in turn drives the ring gear to rotate in the opposite direction to the sun gear. The ring gear drives the guide plate 14 to rotate slowly above the fixed cylinder 6 via the connecting rod 16. The transmission ratio of the planetary gear set 15 is set so that the rotational speed of the guide plate 14 is lower than that of the rotating shaft 5, thereby achieving low-speed pushing of the material by the guide plate 14 and rapid stirring of the material by the stirring element 7.

[0032] Example 2, refer to Figure 5 , Figure 7 This is the second embodiment of the present invention, which differs from the first embodiment in that: multiple rotating rods 17 are fixedly connected to the outer wall of the rotating shaft 5, and a fixed frame 18 is fixedly connected to the other end of the rotating rods 17. A scraper 19 is vertically slidably connected inside the fixed frame 18. When the scraper 19 rotates with the rotating shaft 5, its lower end passes over the top surface of the guide plate 14. Specifically, the scraper 19 can slide freely in the vertical direction inside the fixed frame 18. When the rotating shaft 5 drives the rotating rods 17 to rotate synchronously, the lower end of the scraper 19 first contacts the scraping surface 142 of the guide plate 14, and then slides upward inside the fixed frame 18 and slides into contact with the guide surface 141, thereby actively scraping and pushing the chicken manure material accumulated on the surface of the guide plate 14, and avoiding the material from adhering and accumulating on the surface of the guide plate 14 and affecting the turning effect.

[0033] Reference Figure 7 , Figure 8 A diversion ring 22 is fixedly connected to the inner wall of the upper end of the fixed cylinder 6. Multiple fixed rods 20 are fixedly connected to the top surface of the diversion ring 22. The multiple fixed rods 20 are arranged in a ring-shaped wave pattern. A comb rod 21 is fixedly connected to the rotating rod 17. When the comb rod 21 rotates with the rotating shaft 5, it passes through the fixed rods 20. Specifically, the height of the outer ring of the top surface of the diversion ring 22 is higher than that of the inner ring, forming a flow slope. The ring-shaped wave pattern of the multiple fixed rods 20 forms an interception net. The chicken manure material sliding down from the guide surface 141 is evenly spread onto the diversion ring 22 and flows into the inner area along the slope. During this process, the clumps of material are intercepted by the interception net. When the comb rod 21 rotates along the top surface of the diversion ring 22, the clumps of material are broken and dispersed under the relative shearing action of the comb rod 21 and the fixed rods 20.

[0034] Based on embodiments 1-2, the working principle of this invention is as follows: During use, pre-treated chicken manure is fed into the tank 1 through the inlet at the top. The electric push rod 42 retracts, causing the baffle 41 to flip downwards, opening the outlet 3. The motor drives the rotating shaft 5 and the stirring element 7 to rotate, conveying the material downwards. After the material accumulates to the fermentation height in each storage chamber, the outlet 3 is closed. During fermentation, an external air source supplies air to each annular pipe of the aeration element 12 through the air supply pipe 13. The gas enters the bottom of each storage chamber through the aeration head, passing through the material layer from bottom to top, providing oxygen for aerobic microorganisms. The stirring element 7, in conjunction with the guide plate 14, causes the material to circulate from the periphery to the center and from the center to the periphery within each storage chamber, achieving sufficient vertical material exchange and ensuring full contact between the gas and the material. The exhaust gas, after leaving the material surface, enters the exhaust port 8 and is finally discharged outwards through the upper end of the rotating shaft 5.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
