Description

Technical Field

[0001] The invention relates to the technical field of fermentation devices, in particular to a fermentation device for organic fertilizer for soil remediation. Background Art

[0002] In the field of soil remediation, organic fertilizer is an important remediation material. Its quality and fermentation effect are directly related to the effectiveness of soil remediation. With the sustainable development of agriculture and the enhancement of environmental protection awareness, the demand for efficient and high-quality organic fertilizers for soil remediation is increasing, which also promotes the continuous development and improvement of the technology of organic fertilizer fermentation equipment.

[0003] Currently, there are a variety of fermentation devices for organic fertilizers used for soil remediation on the market. Among them, the more common ones are fermentation equipment based on the traditional stirring principle. Such devices are usually equipped with a stirring shaft and stirring blades. The rotation of the stirring shaft drives the stirring blades to stir the fermentation raw materials to achieve mixing of the raw materials, promote the contact between microorganisms and raw materials during the fermentation process, and thus promote the fermentation reaction.

[0004] However, existing fermentation devices of this type have exposed many defects in actual application. In terms of raw material mixing, the stirring method of traditional stirring devices is relatively simple, and the movement trajectory and direction of the stirring blades are relatively fixed, making it difficult to achieve multi-dimensional mixing of the raw materials. This leads to insufficient mixing of the raw materials. Some raw materials may remain in a piled state for a long time and cannot fully contact with microorganisms. As a result, various biochemical reactions in the fermentation process cannot be fully and quickly carried out, the microorganisms are unevenly distributed in the raw materials, and the nutrients in the raw materials cannot be fully utilized, thereby slowing down the fermentation speed, extending the fermentation cycle, and reducing production efficiency.

[0005] In terms of optimizing the fermentation environment, existing devices have insufficient control over gas exchange and heat distribution within the fermentation system. During the fermentation process, a large number of bubbles will be generated inside the raw materials. These bubbles will hinder the diffusion of oxygen in the air into the fermentation raw materials, restricting the living environment of aerobic microorganisms, reducing their metabolic activity, and being detrimental to the decomposition and conversion of organic matter. At the same time, the presence of bubbles will also cause uneven distribution of heat in the fermentation raw materials, making it difficult to maintain a suitable fermentation temperature range, affecting the growth and metabolic activities of microorganisms, and further reducing fermentation efficiency.

[0017] Compared with the existing technology, it has the following beneficial effects:

[0018] Scraping the raw materials stuck on the inner wall of the fermentation tank by a scraper can effectively prevent raw material residue, avoid contamination of the entire fermentation system due to deterioration of residual raw materials, ensure the purity of the fermentation environment, and improve the quality and safety of fermented products. Continuously scraping the inner wall during the fermentation process greatly reduces the amount of residue on the tank wall after fermentation, making subsequent cleaning work easier and more efficient, and reducing cleaning costs and time costs.

[0019] By moving the flip plate vertically and rotating during the rotation process, the fermentation raw materials can be flipped, causing the raw materials to be displaced and mixed in the vertical direction; the cross stirring plate rotates while moving in the vertical direction to further stir the raw materials. The two cooperate with each other to stir the raw materials from different directions and angles, realizing multi-dimensional mixing of the raw materials, making the raw materials more evenly mixed, which is conducive to full contact between microorganisms and raw materials during the fermentation process and improving the fermentation effect. The even mixing of raw materials can make various biochemical reactions in the fermentation process more sufficient and rapid, and the microorganisms can be evenly distributed in the raw materials, making full use of the nutrients in the raw materials, accelerating the fermentation speed, shortening the fermentation cycle, and improving production efficiency.

[0020] By puncturing the bubbles, the gas exchange area in the fermentation system can be increased, making it easier for oxygen in the air to diffuse into the fermentation raw materials, providing a suitable living environment for aerobic microorganisms, and improving their metabolic activity, thereby accelerating the decomposition and conversion of organic matter. Puncturing the bubbles helps to distribute heat more evenly in the fermentation raw materials, maintain a suitable fermentation temperature range, ensure that the growth and metabolic activities of microorganisms are carried out under optimal conditions, and improve fermentation efficiency. After puncturing the bubbles, the contact between the various components of the fermentation raw materials is closer, which is conducive to the uniform distribution of nutrients, microorganisms and enzymes, making the fermentation reaction more complete, and improving the quality and fertilizer efficiency of organic fertilizers. Puncturing the bubbles can improve the fermentation environment, reduce the generation of anaerobic areas, reduce the accumulation of harmful substances, and ensure the safety and effectiveness of organic fertilizers. By puncturing the bubbles, the fermentation environment is optimized, the activity and metabolic rate of microorganisms are improved, and the decomposition and conversion process of organic matter is accelerated, thereby shortening the entire fermentation cycle, improving production efficiency, and reducing production costs.

[0021] When the cross stirring plate rotates, the swing rod's knocking on its plate surface will generate vibration. This vibration can be transmitted to the fermentation material, dispersing the agglomerated material particles, increasing the contact area between the materials, and facilitating full contact between microorganisms and materials, promoting the fermentation reaction. The swing rod's knocking on the plate surface can shake off the material adhering to the plate surface, keep the plate surface clean, ensure that the stirring plate can continue to play its role effectively, and improve the uniformity and efficiency of stirring. The vibration generated by the knocking treatment can destroy the internal binding force of the material, prevent the material from agglomerating, and keep the fermentation material in a good loose state, which is beneficial to the growth and metabolism of microorganisms.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Combination Figures 1-9 As shown, the present invention provides a technical solution: a fermentation device for organic fertilizer for soil remediation, the main components of which include a fermentation tank 1, a connecting pipe 2 is specially provided on one side of the top of the fermentation tank 1 for the entry of raw materials, and a support frame 3 is designed at the bottom of the fermentation tank 1 to ensure the stability and safety of the entire fermentation tank 1, and a stirring mechanism 4 is specially designed inside the fermentation tank 1. The main function of the stirring mechanism 4 is to perform a counter-flow operation on the fermentation raw materials inside the fermentation tank 1, which can ensure that the raw materials are fully and evenly mixed during the fermentation process, thereby significantly improving the fermentation efficiency and product quality;

[0034] The stirring mechanism 4 includes a driving motor 41 fixedly mounted on the top of the fermentation tank 1, the output end of the driving motor 41 is fixedly connected to a rotating rod 42, the inner cavity of the rotating rod 42 is provided with a guide 44, a flip plate 45 is connected through the guide 44, and the rotation and vertical movement of the flip plate 45 can be controlled, the upper and lower ends of the rotating rod 42 are fixedly connected to a mounting plate 43, the other end of the mounting plate 43 is rotatably connected to a screw rod 46, a cross stirring plate 47 is provided on the screw rod 46, and the rotation and vertical movement of the cross stirring plate 47 are controlled by the screw rod 46, thereby achieving efficient mixing of the fermentation raw materials;

[0035] The guide member 44 includes a slide groove 441 formed in the side wall of the rotating rod 42, and a positioning rod 442 provided in the inner cavity of the rotating rod 42 and rotatably mounted on the inner wall of the fermentation tank 1. The outer wall of the positioning rod 442 is provided with helical teeth 443. These helical teeth 443 cooperate with the slide groove 441 of the rotating rod 42 to ensure the precise movement of the flip plate 45.

[0036] The flip plate 45 is fixedly connected to a connecting shaft 451 on the side close to the rotating rod 42. The outer wall of the connecting shaft 451 is provided with a slider 452 and fixedly connected to a first gear 453. The slider 452 is located in the slide groove 441 and is slidably connected to the rotating rod 42, while the first gear 453 is threadedly connected to the helical gear 443. This design enables the flip plate 45 to rotate and move vertically accurately as needed, thereby achieving efficient stirring of the fermentation raw materials.

[0037] In the internal structure of the fermentation tank 1, the top of the screw rod 46 is fixedly connected to the second gear 461. The outer side of the second gear 461 is tightly meshed with the inner ring gear 463, and the inner ring gear 463 is fixedly mounted on the inner wall of the fermentation tank 1. In addition, a scraper 462 is provided on the outer side of the screw rod 46. This scraper 462 is fixedly mounted on the mounting plate 43. The main function of the scraper 462 is to effectively scrape off the raw materials stuck on the inner wall of the fermentation tank 1 to keep the fermentation tank 1 clean and hygienic.

[0038] A rectangular block 471 is connected to the outer wall of the screw rod 46 by a thread, and a connecting frame 474 is fixedly connected to the outer side of the rectangular block 471. A vertical rod 472 is slidably connected to the connecting frame 474. This vertical rod 472 is fixedly mounted on the mounting plate 43. The connecting frame 474 and the vertical rod 472 cooperate to guide the rectangular block 471 to move in the vertical direction along the screw rod 46. In order to ensure the stability of the vertical rod 472, a gear rod 473 fixedly mounted on the mounting plate 43 is also provided on one side thereof.

[0039] At the inner end of the rectangular block 471, there is a rotatably connected connecting rod 475, on which a cross stirring plate 47 is fixedly mounted. The cross stirring plate 47 is used to stir the raw materials during the fermentation process. A third gear 476 is also fixedly connected to the outer wall of the connecting rod 475. One side of the third gear 476 is meshed with the gear rod 473. Through the meshing relationship, the cross stirring plate 47 can be precisely controlled, thereby ensuring the uniformity and efficiency of the fermentation process.

[0040] In an embodiment of the present invention, by starting the drive motor 41, the rotating rod 42 is driven to perform synchronous rotational motion. The rotation of the rotating rod 42 will further drive the mounting plate 43, the screw rod 46 and the scraper 462 to rotate together. This coordinated rotation action enables the scraper 462 to effectively scrape off the raw materials adhering to the inner wall of the fermentation tank 1. Through this scraping treatment, the raw materials can be effectively prevented from remaining on the inner wall of the fermentation tank 1, and the pollution of the entire fermentation system due to the deterioration of the residual raw materials can be avoided. This not only ensures the purity of the fermentation environment, but also significantly improves the quality and safety of the fermented products. During the fermentation process, the inner wall of the fermentation tank 1 is continuously scraped, which greatly reduces the amount of residue on the tank wall after the fermentation is completed, making the subsequent cleaning work easier and more efficient, thereby reducing the cleaning cost and time cost.

[0041] As the rotating rod 42 rotates, it also drives the flip plate 45 to rotate synchronously. Since the slider 452 is located in the slide groove 441 and can slide freely, the first gear 453 is engaged with the helical gear 443, so that the flip plate 45 can move in the vertical direction and rotate at the same time during the rotation process. This design enables the flip plate 45 to effectively flip the fermentation raw materials, thereby ensuring that the raw materials can be fully mixed and contacted during the fermentation process.

[0042] At the same time, when the rotating rod 42 drives the screw rod 46 to rotate, due to the meshing of the second gear 461 and the inner gear ring 463, the screw rod 46 can rotate while rotating. This rotation movement enables the screw rod 46 to drive the rectangular block 471 to move in the vertical direction. It is worth noting that the movement direction of the rectangular block 471 is opposite to the movement direction of the flip plate 45. In addition, due to the meshing relationship between the third gear 476 and the gear rod 473, when the rectangular block 471 moves in the vertical direction, the meshing relationship between the third gear 476 and the gear rod 473 can drive the connecting rod 475 and the cross stirring plate 47 to rotate. This rotation enables the cross stirring plate 47 to effectively stir the fermentation raw materials, thereby ensuring uniform mixing of the fermentation raw materials.

[0043] During the movement of the flip plate 45 and the cross stirring plate 47, they are in opposite states, one rising and the other falling, and the cross stirring plate 47 and the flip plate 45 are vertically staggered. This design realizes the relative rotation of the raw materials during the fermentation and stirring process of the product raw materials, thereby improving the fluidity of the stirring. At the same time, it can also realize the downward movement of the upper layer of materials and the upward movement of the lower layer of materials, which not only improves the stirring efficiency but also avoids the problem of fault-type raw materials during fermentation.

[0044] Through the vertical movement and rotation of the flip plate 45 during the rotation process, the fermentation raw materials can be effectively flipped, so that the raw materials are displaced and mixed in the vertical direction. The cross stirring plate 47 rotates while moving in the vertical direction to further stir the raw materials. The two cooperate with each other to stir the raw materials from different directions and angles, realizing multi-dimensional mixing of the raw materials. This multi-dimensional mixing makes the raw materials more evenly mixed, which is beneficial to the full contact between the microorganisms and the raw materials during the fermentation process, thereby improving the fermentation effect. The uniform mixing of raw materials can make the various biochemical reactions in the fermentation process more sufficient and rapid. The microorganisms can be evenly distributed in the raw materials, fully utilizing the nutrients in the raw materials, accelerating the fermentation speed, shortening the fermentation cycle, and improving production efficiency.

[0045] Example 2: Combination Figure 7 、 Figure 8 、 Figure 9 As shown, based on the first embodiment, reciprocating grooves 478 are specially designed in the internal structure of the cross stirring plate 47. These reciprocating grooves 478 are precisely opened in the inner cavity of the stirring plate. In these reciprocating grooves 478, a row of piercing rods 479 are designed to be slidably connected to achieve their reciprocating motion. In order to ensure that the movement of the piercing rods 479 is properly restricted and controlled, limit blocks 480 are fixedly connected to the outer wall thereof. A damping mechanism is cleverly set between these limit blocks 480 and the inner wall of the reciprocating grooves 478, that is, a first damping spring 481 is sleeved on the piercing rod 479, which can provide the necessary damping force when the piercing rod 479 moves to ensure In order to ensure the smoothness of movement, in addition, the inner wall of the reciprocating groove 478 is also slidably connected to a cross bar 482, and the two ends of the cross bar 482 are respectively fixedly connected to a control rod 484 and a second damping spring 485. The other end of the control rod 484 is designed to be slidably installed in the reciprocating groove 478, and the other end of the second damping spring 485 is fixedly connected to the inner wall of the reciprocating groove 478 to provide additional damping effect. In order to further enhance the stability of the structure and the control accuracy, a row of trapezoidal blocks 483 are fixedly connected to the outer wall of the cross bar 482. The outer walls of these trapezoidal blocks 483 are slidably adapted to one end of the puncturing rod 479, ensuring the precise position control of the puncturing rod 479 during the reciprocating motion.

[0046] The structure of the cross stirring plate 47 also includes a connecting rod 475, the outer wall of which is provided with a disc 477 fixedly mounted on the rectangular block 471. The disc 477 not only serves as a connection and support, but also has reciprocating grooves 478 on its surface. These reciprocating grooves 478 cooperate with the reciprocating grooves 478 inside the cross stirring plate 47 to form a complex reciprocating motion system. Through this design, efficient and precise stirring of the cross stirring plate 47 during operation can be achieved, ensuring the uniformity and continuity of the stirring process.

[0047] In the embodiment of the present invention, when the rectangular block 471 is located on the screw rod 46 and moves in the vertical direction, due to the precise meshing relationship between the third gear 476 and the gear rod 473, this mechanism can effectively drive the flip plate 45 and the cross stirring plate 47 to rotate accordingly. As the cross stirring plate 47 rotates, it can drive the cross bar 482 and the control rod 484 to rotate synchronously. During the rotation of the control rod 484, the end of the control rod 484 slides in the reciprocating groove 478. This design enables the control rod 484 to be able to cooperate with the elastic force of the second damping spring 485 under the action of the reciprocating groove 478, thereby driving the cross bar 482 and the trapezoidal block 483 to reciprocate. During the reciprocating movement, the trapezoidal block 483 cooperates with the elastic force of the first damping spring 481 to push the puncture rod 479 to reciprocate up and down. This reciprocating movement enables the puncture rod 479 to effectively puncture the bubbles generated when the fermentation raw materials are stirred;

[0048] By puncturing the bubbles, the gas exchange area in the fermentation system can be significantly increased, making it easier for oxygen in the air to diffuse into the fermentation raw materials, providing a more suitable living environment for aerobic microorganisms. This not only improves the metabolic activity of aerobic microorganisms, but also accelerates the decomposition and transformation of organic matter. Puncturing the bubbles helps to distribute heat more evenly in the fermentation raw materials, maintain a suitable fermentation temperature range, and ensure that the growth and metabolic activities of microorganisms are carried out under optimal conditions, thereby improving fermentation efficiency. In addition, after puncturing the bubbles, the contact between the various components of the fermentation raw materials becomes closer, which is conducive to the uniform distribution of nutrients, microorganisms and enzymes, making the fermentation reaction more complete, thereby improving the quality and fertilizer efficiency of organic fertilizers. Puncturing the bubbles can also improve the fermentation environment, reduce the generation of anaerobic areas, reduce the accumulation of harmful substances, and ensure the safety and effectiveness of organic fertilizers. By puncturing the bubbles, the fermentation environment is optimized, the activity and metabolic rate of microorganisms are improved, and the decomposition and transformation process of organic matter is accelerated, thereby shortening the entire fermentation cycle, improving production efficiency, and reducing production costs.

[0049] Example 3: Combination Figure 8As shown, on the basis of Example 2, the upper and lower ends of the rectangular block 471 are fixedly connected to a pair of arc frames 486, and the axial position of these arc frames 486 is carefully designed so that the swing rod 487 can be smoothly rotated and installed on the rectangular block 471. The other end of the swing rod 487 is precisely corresponding to the position of the cross stirring plate 47, ensuring that the two can interact effectively. In addition, the swing rod 487 is designed to slide on the arc frame 486 to adapt to different working conditions. In order to ensure the stability of the swing rod 487 and control its movement, arc springs 488 are respectively provided on both sides thereof and are mounted on the arc frames 486. The function of these arc springs 488 is to provide a pushing force toward the middle when the swing rod 487 deviates from the center position, thereby ensuring that the swing rod 487 can be driven by the rotation of the cross stirring plate 47 and rotate to one side to realize its design function.

[0050] In the embodiment of the present invention, when the cross stirring plate 47 rotates during the stirring process, one of its plate surfaces pushes the swing rod 487 to move to one side, and at the same time compresses the arc spring 488. As the cross stirring plate 47 continues to rotate, when the plate surface no longer contacts the swing rod 487, the swing rod 487 can automatically return to its initial position due to the elastic restoring force of the arc spring 488. This process enables the swing rod 487 to effectively knock the plate surface of the next incoming cross stirring plate 47;

[0051] During the rotation of the cross stirring plate 47, the knocking of the swing rod 487 on the plate surface not only generates vibration, but also this vibration can be effectively transmitted to the fermentation material. This vibration helps to break up the agglomerated material particles and disperse them, thereby increasing the contact area between the material particles. This increased contact area is conducive to the full contact between the microorganisms and the material, thereby promoting the smooth progress of the fermentation reaction. The knocking action of the swing rod 487 can also shake off the material adhering to the plate surface of the cross stirring plate 47, keep the plate surface clean, and ensure that the stirring plate can continue to function effectively. In addition, the vibration generated by the knocking treatment can destroy the internal binding force of the material, prevent the material from agglomerating, and maintain the fermentation material in a good loose state, which is extremely beneficial to the growth and metabolism of microorganisms, thereby improving the uniformity and efficiency of stirring.
