Description

Technical Field

[0001] This invention relates to the field of organic fertilizer processing technology, specifically to an organic fertilizer processing equipment and an organic fertilizer processing method. Background Technology

[0002] Organic fertilizer is an environmentally friendly fertilizer made from natural organic materials such as animal and plant waste, agricultural and forestry straw, and livestock and poultry manure through harmless treatment and composting. It is rich in organic matter, nitrogen, phosphorus, potassium and trace elements, which can provide crops with comprehensive nutrition, improve soil aggregate structure and enhance soil water and fertilizer retention capacity. It is widely used in the planting of food crops, cash crops and facility agriculture.

[0003] Organic fertilizer manufacturing centers on the resource utilization of organic waste and involves multiple processing steps. First, raw materials such as livestock and poultry manure and straw are crushed, sieved, and separated into solid and liquid components, with conditioners added to adjust moisture content and carbon-nitrogen ratio. Then, fermentation equipment is used under suitable conditions with ventilation, relying on microbial action to complete the composting and detoxification process. Finally, post-processing steps such as sieving, granulation, drying, cooling, and coating produce a finished product with uniform granules and stable nutrients. Some production lines are equipped with intelligent systems to achieve precise parameter control.

[0004] However, existing organic fertilizer fermentation and processing equipment can only achieve simple stirring-type coarse processing. The raw materials are prone to agglomeration, resulting in insufficient contact between microorganisms and the inability to finely crush the raw materials. At the same time, aeration is mostly continuous, which has low aeration efficiency and easily leads to energy waste. The materials in the tank are also prone to uneven distribution, ultimately resulting in a long fermentation cycle and poor composting effect, making it difficult to meet the needs of high-efficiency processing of organic fertilizers. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an organic fertilizer processing equipment and an organic fertilizer processing method, which can effectively solve the problems of easy agglomeration of raw materials, insufficient contact of microorganisms, low aeration efficiency and high energy consumption, uneven material distribution, long fermentation cycle and poor composting effect in the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides an organic fertilizer processing device, including a fermentation device. The fermentation device includes a fermentation tank, and a preliminary kneading component is provided inside the fermentation tank. The preliminary kneading component is used to perform preliminary kneading on the raw materials. The preliminary kneading component includes a central rod, and a planetary gear is provided on the side wall of the central rod. An eccentric rod is fixedly connected to one side of the planetary gear, and the eccentric rod is eccentrically installed on one side of the planetary gear.

[0008] A secondary kneading assembly is provided between the central rod and the eccentric rod. The secondary kneading assembly is used to intensify the kneading of the raw materials. The secondary kneading assembly includes a mounting block, which is fixedly connected to the outer wall of the eccentric rod. A kneading rod is slidably connected inside the mounting block. A kneading groove is provided on the outer wall of the central rod, and a kneading toothed ring is fixedly connected inside the kneading groove.

[0009] Preferably, an aeration inlet pipe is installed on one side of the fermentation tank, a drive motor is installed on the other side of the fermentation tank, support legs are installed at the bottom of the fermentation tank, a pressure relief valve is installed at the top of the fermentation tank, and an inlet / outlet is provided at the top of the fermentation tank.

[0010] Preferably, the preliminary kneading assembly includes a central rod penetrating the fermenter, one end of which is fixedly connected to the output shaft of the drive motor, and the other end of which is connected to an aeration inlet pipe. A central gear ring is fixedly connected to the outer wall of the central rod, and a planetary gear is meshed with the central gear ring. An outer gear ring is meshed with the outer side of the planetary gear ring, and the outer gear ring is fixedly connected to the inner wall of the fermenter.

[0011] Preferably, the fermentation tank is provided with a right-handed spiral blade and a left-handed spiral blade for conveying raw materials to the center. The right-handed spiral blade and the left-handed spiral blade are fixedly connected to the inner wall of the fermentation tank. A baffle is provided in the fermentation tank and is disposed on the inner wall of the fermentation tank. The eccentric rod and the baffle are connected by an elastic membrane.

[0012] Preferably, the mounting block has a kneading groove, and the kneading rod is slidably connected in the kneading groove. The kneading groove and the kneading rod are connected by a kneading spring. A deflection groove is provided on one side of the bottom of the mounting block, and the mounting block and the kneading rod slide in the kneading groove.

[0013] Preferably, the central rod is connected to the aeration inlet pipe via an aeration assembly. The aeration assembly is disposed inside the central rod and includes an aeration mounting groove formed on one side of the central rod. A connecting pipe is inserted into the aeration mounting groove on the side near the aeration inlet pipe, and the aeration inlet pipe is inserted into the other side of the connecting pipe.

[0014] Preferably, a cross-shaped connecting rod is fixedly connected to the outer wall of the connecting pipe, the cross-shaped connecting rod is fixedly connected to the outside of the fermenter, an air intake pipe is provided inside the central rod, one end of the air intake pipe is fixedly connected to the connecting pipe, and an air outlet is provided on the outer wall of the air intake pipe.

[0015] Preferably, a pulse assembly is provided inside the central rod. The pulse assembly is connected to the aeration assembly and is used to perform pulse aeration into the fermenter. The pulse assembly includes a fixed plate fixedly connected to the outer wall of the air intake pipe, and a sliding plate slidably connected to the outer wall of the air intake pipe. A pulse air chamber is formed between the fixed plate and the sliding plate. The pulse air chamber is a sealed space, and the fixed plate and the sliding plate are connected by a pulse spring.

[0016] Preferably, a sealing ring is fixedly connected to one side of the sliding disk, the side wall of the sealing ring has a communication port, and the inner wall of the central rod has a pulse outlet. The sealing ring is used to block the pulse outlet, and the communication port is used to connect the pulse outlet.

[0017] This solution also provides an organic fertilizer processing method, including the following steps:

[0018] S1: The pretreated organic fertilizer raw materials are put into the fermentation tank through the inlet and outlet. The tank is closed to ensure airtightness. The equipment passages such as the drive motor and aeration inlet pipe are checked to ensure that all components are in a ready-to-work state and ready for subsequent processing.

[0019] S2: The start-up drive motor drives the central rod to rotate, and through transmission, the eccentric rod completes the initial kneading through compound motion; the kneading rod of the secondary kneading component elastically fits the kneading tooth ring, finely grinding the raw materials, thoroughly breaking up clumps, and increasing the contact area of ​​microorganisms.

[0020] S3: Open the aeration inlet pipe to continuously aerate the fermenter through the aeration components. At the same time, the pulse component operates automatically, forming intermittent high-pressure pulse aeration through the pulse air chamber to disperse the raw materials and prevent blockage. It also causes the materials to turn slightly, improving the mixing degree of oxygen and raw materials.

[0021] S4: Keep the fermentation tank sealed and regulate the pressure inside the tank by relying on the pressure relief valve. Through the fine raw materials of two-stage kneading and the sufficient oxygen supply of efficient aeration, the microorganisms can fully metabolize and achieve rapid decomposition of organic fertilizer raw materials, ensuring that the materials are evenly distributed in the tank throughout the process.

[0022] S5: After the raw materials have matured, stop the drive motor and aeration system, open the inlet and outlet, and use the internal structure of the fermentation tank to assist in the discharge of materials. Collect the matured organic fertilizer raw materials, which can then undergo subsequent processing steps such as granulation and drying to obtain the finished organic fertilizer.

[0023] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0024] The initial kneading component of this equipment is driven by a motor that rotates the central rod. Utilizing a planetary transmission structure consisting of a central gear ring, planetary gears, and an external gear ring, the eccentric rod undergoes a combined revolution and rotation. This, combined with the material gathering action of the right-hand and left-hand spiral blades inside the tank and the limiting effect of the baffles, completes the initial kneading and dispersing of the organic fertilizer raw materials. This structure replaces the traditional single-stage mixing and coarse processing mode. The combined motion results in a more uniform kneading force with a wider coverage area, effectively breaking up initial agglomerates of raw materials and preventing incomplete fermentation caused by material residue at the edges of the tank. Simultaneously, the elastic membrane sealing design between the eccentric rod and the baffles prevents raw materials from getting stuck in equipment gaps while not restricting the movement of the kneading component, improving the stability of equipment operation and laying the foundation for subsequent fine crushing, significantly improving the overall efficiency of raw material pretreatment.

[0025] The secondary kneading component performs a compound motion synchronously with the eccentric rod. The kneading rod within the mounting block is elastically connected via a kneading spring, always maintaining close contact with the kneading toothed ring within the kneading groove of the central rod. Within the adaptive space of the deflection groove, friction and compression occur with the toothed ring, achieving fine grinding. This elastic fit and toothed ring design can accommodate raw material agglomerates of different particle sizes, thoroughly breaking up stubborn clumps and solving the problem of incomplete raw material crushing in traditional equipment. This significantly increases the contact area between the raw material and microorganisms. Simultaneously, the kneading operation is confined within the groove, coordinating with material aggregation to prevent kneading failure. Furthermore, this structure, linked with the primary kneading component, requires no additional drive, reducing equipment energy consumption and maintenance costs while achieving two-stage fine crushing, fundamentally optimizing the raw material processing effect.

[0026] The aeration component integrates the aeration path inside the central rod. The aeration inlet pipe and the air outlet pipe are connected by a fixed connecting pipe. When the central rod rotates, the connecting pipe remains stationary. Gas is continuously discharged from the air outlet of the air outlet pipe into the deep center of the material, realizing basic deep aeration. The pulse component is connected to the aeration component. Gas enters the sealed pulse air chamber and pushes the sliding disc to move, so that the sealing ring connection port is aligned with the pulse outlet to form high-pressure pulse aeration. After the air pressure is released, the spring resets and seals, realizing intermittent pulse air supply. The two form a dual air supply mode. This integrated aeration structure allows oxygen to diffuse from the center of the material, solving the problem of deep oxygen deficiency in traditional surface aeration. Aeration and kneading are carried out simultaneously, allowing oxygen to fully contact the dispersed raw materials and improving oxygen utilization. Pulsed air supply conforms to the metabolic patterns of microorganisms, avoiding the energy waste and excessive oxygen problems of continuous aeration. The high-pressure airflow can also disperse residual raw materials at the aeration ports to prevent blockage, and drive the raw materials to gently turn over to optimize distribution, reducing additional energy consumption for turning over. This ensures that all microorganisms in the tank are in a suitable oxygen supply environment, significantly improving the organic fertilizer composting efficiency and effectively shortening the fermentation cycle. At the same time, the fixed pipeline design ensures the long-term stable operation of the aeration system, adapting to the needs of continuous industrial production. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] The present invention will be further described below with reference to embodiments.

[0039] Example 1: Refer to Figures 1 to 8 An organic fertilizer processing device includes a fermentation device 1, which includes a fermentation tank 11. An aeration inlet pipe 14 is installed on one side of the fermentation tank 11, a drive motor 15 is installed on the other side of the fermentation tank 11, a support leg 12 is installed at the bottom of the fermentation tank 11, a pressure relief valve 13 is installed at the top of the fermentation tank 11, and an inlet / outlet port 16 is provided at the top of the fermentation tank 11.

[0040] The fermentation tank 11 is equipped with a preliminary kneading component 2, which is used to knead the raw materials. The preliminary kneading component 2 includes a central rod 21, a planetary gear 23 is provided on the side wall of the central rod 21, and an eccentric rod 25 is fixedly connected to one side of the planetary gear 23. The eccentric rod 25 is eccentrically installed on one side of the planetary gear 23.

[0041] The initial kneading assembly 2 includes a central rod 21 that runs through the fermentation tank 11. One end of the central rod 21 is fixedly connected to the output shaft of the drive motor 15, and the other end of the central rod 21 is connected to the aeration inlet pipe 14. A central gear ring 22 is fixedly connected to the outer wall of the central rod 21. A planetary gear 23 is meshed with the central gear ring 22. An outer gear ring 24 is meshed with the outer side of the planetary gear 23. The outer gear ring 24 is fixedly connected to the inner wall of the fermentation tank 11.

[0042] The fermentation tank 11 is equipped with a right-handed spiral blade 27 and a left-handed spiral blade 28 for conveying raw materials to the center. The right-handed spiral blade 27 and the left-handed spiral blade 28 are fixedly connected to the inner wall of the fermentation tank 11. A baffle 26 is provided inside the fermentation tank 11 and is located on the inner wall of the fermentation tank 11. The eccentric rod 25 and the baffle 26 are connected by an elastic membrane 29.

[0043] Specifically, the initial kneading component 2 uses a drive motor 15 as its power source, driving the central rod 21 that runs through the fermentation tank 11 to rotate. The central gear ring 22 on the outer side of the central rod 21 meshes with the planetary gear 23, which in turn meshes with the outer gear ring 24 fixed to the inner wall of the fermentation tank 11, forming a planetary gear transmission structure. This causes the eccentric rod 25, which is eccentrically mounted on one side of the planetary gear 23, to perform a compound motion of revolution and rotation, forming a differential rotation with the central rod 21, thus achieving the initial kneading and dispersing of the organic fertilizer raw materials in the tank. The right-hand and left-hand spiral blades 28 fixed to the inner wall of the fermentation tank 11 transport the raw materials from the edge of the tank to the center, forming a material gathering effect in conjunction with the baffle 26 connected to the inner wall, allowing the raw materials to concentrate in the central area and avoiding insufficient fermentation of the raw materials remaining on both sides. At the same time, the elastic membrane 29 between the eccentric rod 25 and the baffle 26 provides a partial seal, preventing the raw materials from getting stuck in the gaps while not restricting the compound motion of the eccentric rod 25, ensuring smooth kneading.

[0044] The preliminary kneading component 2 replaces the single stirring structure with a compound motion driven by a planetary gear 23 and an eccentric rod 25. This results in a more uniform kneading force with a wider coverage area, effectively breaking up initial clumps of raw materials and significantly increasing the contact area between the raw materials and microorganisms, laying the foundation for subsequent composting and fermentation. Compared to the problem of uneven material distribution in existing equipment, the coordinated design of the right-hand spiral blades 27 and left-hand spiral blades 28 with the baffle 26 enables the directional aggregation of raw materials in the tank towards the kneading area, preventing raw materials from accumulating at the tank's edges and improving the overall efficiency of raw material kneading. The sealing connection design of the elastic membrane 29 ensures a clean working environment inside the fermentation tank 11 and makes the transmission structure of the kneading component more stable, reducing the probability of equipment failure. At the same time, the integrated transmission and kneading design of this component reduces energy consumption while achieving efficient preliminary kneading, meeting the energy-saving requirements of organic fertilizer processing, and further optimizing the operational efficiency and stability of raw material pretreatment compared to existing technologies.

[0045] A secondary kneading assembly 3 is provided between the central rod 21 and the eccentric rod 25. The secondary kneading assembly 3 is used to strengthen the kneading of the raw materials. The secondary kneading assembly 3 includes a mounting block 31, which is fixedly connected to the outer wall of the eccentric rod 25. A kneading rod 34 is slidably connected in the mounting block 31. A kneading groove 36 is provided on the outer wall of the central rod 21. A kneading toothed ring 37 is fixedly connected in the kneading groove 36.

[0046] The mounting block 31 has a kneading groove 32, and a kneading rod 34 is slidably connected in the kneading groove 32. The kneading groove 32 and the kneading rod 34 are connected by a kneading spring 33. A deflection groove 35 is provided on one side of the bottom of the mounting block 31, and the mounting block 31 and the kneading rod 34 slide in the kneading groove 36.

[0047] Specifically, the secondary kneading component 3 undergoes a compound motion driven by the planetary gear 23 of the primary kneading component 2. The mounting block 31 is fixedly connected to the outer wall of the eccentric rod 25, and its internal kneading groove 32 is elastically connected to the kneading rod 34 through the kneading spring 33. When the eccentric rod 25 drives the mounting block 31 and the kneading rod 34 to extend into the kneading groove 36 outside the central rod 21, the elastic force of the kneading spring 33 makes the kneading rod 34 always closely fit with the kneading tooth ring 37 in the groove. Under the movement of the eccentric rod 25, the kneading rod 34 and the kneading toothed ring 37 generate relative friction and compression. At the same time, the deflection groove 35 at the bottom of the mounting block 31 provides the kneading rod 34 with adaptive deflection space. This deflection can also knead the raw material with greater force without damaging it. Meanwhile, due to the connection of the kneading spring 33, the kneading rod 34 will not detach from the mounting block 31 through the deflection groove 35. The kneading rod 34 can adjust the contact angle according to the actual size of the raw material clumps. Within the limited space of the kneading groove 36, the raw material that has been initially kneaded is subjected to secondary fine kneading and grinding to completely break up the stubborn clumps.

[0048] The secondary kneading component 3, through its elastic connection and toothed ring design, achieves adaptive and enhanced kneading of raw materials, solving the problems of raw material clumping and incomplete crushing in traditional equipment. This significantly increases the contact area between the raw materials and microorganisms, laying a solid foundation for subsequent microbial metabolism during fermentation. The elastic fit design of the kneading rod 34 adapts to clumping of raw materials of different particle sizes, avoiding equipment jamming caused by rigid kneading and improving operational stability. The spatial design of the deflection groove 35 makes the kneading action more flexible and the grinding effect more uniform. Simultaneously, as the eccentric rod 25 moves within the kneading groove 36, it defines the kneading operation area. Combined with the material gathering effect of the spiral blades inside the tank, it avoids kneading failure caused by material dispersion, improving overall crushing efficiency. This structure, together with the primary kneading component 2, forms a two-stage kneading system, making the raw material crushing more refined, effectively shortening the fermentation cycle, improving the organic fertilizer composting effect, and featuring a compact overall structure with strong linkage to the main equipment body. It requires no additional drive, reducing equipment energy consumption and maintenance costs.

[0049] The central rod 21 is connected to the aeration inlet pipe 14 via the aeration assembly 4. The aeration assembly 4 is installed inside the central rod 21. The aeration assembly 4 includes an aeration mounting groove 41 opened on one side of the central rod 21. A connecting pipe 43 is inserted into the side of the aeration mounting groove 41 near the aeration inlet pipe 14, and the aeration inlet pipe 14 is inserted into the other side of the connecting pipe 43.

[0050] A cross connecting rod 42 is fixedly connected to the outer wall of the connecting pipe 43. The cross connecting rod 42 is fixedly connected to the outside of the fermenter 11. An air intake pipe 44 is provided inside the central rod 21. One end of the air intake pipe 44 is fixedly connected to the connecting pipe 43. An air outlet 45 is opened on the outer wall of the air intake pipe 44.

[0051] Specifically, the aeration component 4 provides basic aeration and oxygen supply for organic fertilizer fermentation. Its connecting pipe 43 is fixed to the outside of the fermentation tank 11 via a cross connecting rod 42. One end is inserted into the aeration inlet pipe 14, and the other end is connected to the air intake pipe 44 inside the central rod 21, thus decoupling the aeration path from the rotation of the central rod 21 and ensuring stable gas supply. After the aeration inlet pipe 14 delivers oxygen-containing gas to the connecting pipe 43, it is evenly conducted through the air intake pipe 44. The gas is continuously discharged from the air outlet 45 on the side wall of the air intake pipe 44, completing the basic aeration operation. The aeration component 4, relying on the hollow structure design of the central rod 21, integrates the aeration path inside the central rod 21 of the kneading system, allowing the gas to diffuse from the center of the material in the fermentation tank 11 to the surrounding area. This is synchronized with the kneading action driven by the drive motor 15, allowing oxygen to be directly delivered to the deep layers of the material. This is suitable for the closed fermentation physical environment inside the organic fertilizer fermentation tank 11, realizing the linkage operation of kneading and crushing with aeration and oxygen supply.

[0052] The aeration component 4, through its hollow shaft deep aeration design, ensures that all organic fertilizer raw materials in different locations within the fermentation tank 11 receive sufficient oxygen, significantly enhancing the overall activity of aerobic microorganisms and laying a crucial oxygen supply foundation for the composting of raw materials. Simultaneously, the aeration component 4 works in sync with the kneading system, with the aeration process occurring concurrently with the kneading and crushing of the raw materials. This allows oxygen to fully contact the dispersed raw materials, improving oxygen utilization and resolving the problem of insufficient microbial contact caused by raw material clumping in existing technologies. The connecting pipe 43 is fixed by a cross-shaped connecting rod 42 and does not rotate with the central rod 21, ensuring the sealing and stability of the aeration path and preventing pipe loosening and leakage caused by equipment operation, thus reducing equipment maintenance costs. Furthermore, continuous basic aeration prevents organic fertilizer raw material particles from entering the air intake pipe 44 from the air outlet 45, structurally mitigating the risk of blockage inside the aeration port and ensuring the long-term stable operation of the aeration system, making it suitable for the industrial continuous production needs of organic fertilizer processing.

[0053] A pulse assembly 5 is installed inside the central rod 21. The pulse assembly 5 is connected to the aeration assembly 4. The pulse assembly 5 is used to perform pulse aeration in the fermenter 11. The pulse assembly 5 includes a fixed plate 51 fixedly connected to the outer wall of the air intake pipe 44. A sliding plate 52 is slidably connected to the outer wall of the air intake pipe 44. A pulse air chamber 54 is formed between the fixed plate 51 and the sliding plate 52. The pulse air chamber 54 is a closed space. The fixed plate 51 and the sliding plate 52 are connected by a pulse spring 53.

[0054] A sealing ring 55 is fixedly connected to one side of the sliding disk 52. A connecting port 56 is opened on the side wall of the sealing ring 55. A pulse outlet 57 is opened on the inner wall of the center rod 21. The sealing ring 55 is used to block the pulse outlet 57, and the connecting port 56 is used to connect the pulse outlet 57.

[0055] Specifically, the pulse assembly 5 is located inside the central rod 21 and is connected to the aeration assembly 4. The outer wall of the air intake pipe 44 is fixedly connected to the fixed plate 51, and the sliding plate 52 is slidably sleeved on the air intake pipe 44. The two form a sealed pulse air chamber 54 and are connected by a pulse spring 53. The sealing ring 55 at the side end of the sliding plate 52 is adapted to seal the pulse outlet 57 on the inner wall of the central rod 21. During aeration, a portion of the gas enters the pulse gas chamber 54. As the gas pressure increases, it pushes the sliding disc 52 to compress the pulse spring 53, causing the sealing ring 55 to move synchronously. When the connecting port 56 of the sealing ring 55 aligns with the pulse outlet 57, the high-pressure gas in the gas chamber is rapidly injected into the fermenter 11 through the connecting port 56 and the pulse outlet 57 to form pulse aeration. After the gas pressure is released, the elastic rebound force of the pulse spring 53 pulls the sliding disc 52 to reset, and the sealing ring 55 re-seals the pulse outlet 57. This process is repeated to complete the intermittent pulse gas supply. This process is synchronized with the basic aeration of the central rod 21, which is suitable for the closed fermentation physical environment inside the tank for organic fertilizer fermentation.

[0056] The pulse component 5 enables high-pressure pulse jetting. The strong airflow impact directly disperses and cleans residual raw material particles at the pulse outlet 57 and its surrounding area, preventing blockage caused by the accumulation and agglomeration of organic fertilizer raw materials at the aeration port. Combined with the anti-backflow effect of basic aeration, it significantly reduces the manual maintenance cost of the aeration system and is suitable for the processing characteristics of organic fertilizer raw materials that are prone to agglomeration. Intermittent pulse aeration is more in line with the metabolic patterns of aerobic microorganisms. The high-pressure airflow can break the local static state of the material in the tank, allowing oxygen to mix more evenly with the refined raw materials after kneading, improving oxygen utilization, and avoiding the problems of excessive oxygen in the tank and reduced microbial metabolic efficiency caused by continuous aeration. The impact of the pulse airflow can cause the raw materials in the tank to be slightly agitated, assisting the multi-stage kneading system to optimize material distribution, reducing the energy consumption of individual material turning, and ensuring that microorganisms in all areas of the fermentation tank 11 are in a suitable oxygen supply environment, significantly improving the organic fertilizer composting efficiency, effectively shortening the fermentation cycle, and solving the technical pain points of low aeration efficiency and poor fermentation effect of traditional equipment.

[0057] Example 2: Refer to Figures 1 to 8 An organic fertilizer processing method includes:

[0058] S1: The pre-treated organic fertilizer raw material is put into the fermentation tank 11 through the inlet / outlet 16. The tank is closed to ensure airtightness. The drive motor 15, aeration inlet pipe 14 and other equipment passages are checked to ensure that all components are in standby mode and ready for subsequent processing.

[0059] S2: Start the drive motor 15 to drive the center rod 21 to rotate, and through transmission, the eccentric rod 25 completes the initial kneading by performing a compound motion; the kneading rod 34 of the secondary kneading component 3 elastically fits the kneading tooth ring 37 to finely grind the raw materials, thoroughly break up the clumps, and increase the contact area of ​​microorganisms;

[0060] S3: Open the aeration inlet pipe 14, and continuously aerate the fermenter 11 through the aeration component 4. At the same time, the pulse component 5 operates automatically, forming intermittent high-pressure pulse aeration through the pulse air chamber 54 to disperse the raw materials and prevent blockage, and to drive the materials to turn slightly, thereby improving the mixing degree of oxygen and raw materials.

[0061] S4: Keep fermentation tank 11 sealed, regulate the pressure inside the tank by relying on pressure relief valve 13, and allow microorganisms to fully metabolize through two-stage kneading of refined raw materials and efficient aeration to achieve rapid decomposition of organic fertilizer raw materials, ensuring that the materials are evenly distributed in the tank throughout the process.

[0062] S5: After the raw materials have matured, stop the drive motor 15 and the aeration system, open the inlet and outlet 16, use the internal structure of the fermentation tank 11 to assist in the discharge of materials, collect the matured organic fertilizer raw materials, and then carry out subsequent processing steps such as granulation and drying to obtain the finished organic fertilizer.

[0063] The working principle of this invention is as follows:

[0064] The core working principle of this equipment revolves around two core systems: multi-stage kneading and crushing, and linked aeration and oxygen supply. Through structural linkage, the pretreatment of raw materials and fermentation aeration are carried out simultaneously. The drive motor 15 drives the central rod 21 to rotate. The central gear ring 22, planetary gear 23 and external gear ring 24 form a planetary transmission structure, which makes the eccentric rod 25 perform a compound motion of revolution and rotation, completing the initial kneading of the raw materials. The right-hand and left-hand spiral blades 28 on the inner wall of the fermentation tank 11 gather the raw materials at the edge towards the center. The baffle 26 and the elastic membrane 29 cooperate to prevent the raw materials from getting stuck, ensuring full coverage of the initial kneading. The secondary kneading component 3 on the eccentric rod 25 moves synchronously with it. Under the elastic force of the kneading spring 33, the kneading rod 34 is closely fitted with the kneading tooth ring 37 in the kneading groove 36 of the central rod 21. Through relative friction and extrusion, the stubborn agglomerates are finely broken down. The deflection groove 35 also provides the kneading rod 34 with adaptive deflection space, making the crushing more thorough. The two-stage kneading greatly increases the contact area between the raw materials and microorganisms.

[0065] The aeration system and kneading system are deeply integrated, achieving dual air supply of basic continuous aeration and pulse aeration, adapting to the metabolic needs of aerobic microorganisms. The aeration inlet pipe 14 delivers oxygen-containing gas to the air intake pipe 44 within the central rod 21 via a fixed connecting pipe 43. The gas is continuously discharged from the outlet 45, diffusing from the center of the material outwards, achieving deep basic aeration. Furthermore, the connecting pipe 43 is decoupled from the central rod 21, ensuring stable air supply. The pulse component 5 within the air intake pipe 44 works synchronously. After the gas enters the sealed pulse chamber 54, it pushes the sliding disc 52 to move, aligning the connection port 56 of the sealing ring 55 with the pulse outlet 57, causing high-pressure gas to be rapidly ejected, forming pulse aeration. After the pressure is released, the pulse spring 53 pulls the sliding disc 52 back to its original position, repeatedly achieving intermittent pulse aeration. The strong airflow not only disperses the raw materials to prevent blockage of the aeration ports but also slightly agitates the materials, allowing for more uniform mixing of oxygen and refined raw materials, improving aeration efficiency and microbial activity, and effectively shortening the fermentation cycle.
