Description

Technical Field

[0001] The invention relates to the technical field of fertilizer production, and in particular to a granulating device for producing special fertilizer containing manno-oligosaccharide. Background Art

[0002] The granulation device in fertilizer production is the key equipment for granulating raw materials. It can process fertilizer raw materials into uniform particles for better storage, transportation and use. There are generally many types of fertilizer granulation devices, and the common ones include the following: The disc granulator is a device that gradually gathers materials into particles through a rotating disc. The angle and speed of the disc can be adjusted to control the particle size and molding quality. The drum granulator uses a rotating large cylinder to make the materials rub against each other and gather in the cylinder to finally form particles. It is suitable for large-scale production and is often used in the production of compound fertilizers. The extrusion granulator forms particles by compressing the material and extruding it through a die. It is usually used in the production of organic fertilizers and has the characteristics of high efficiency and low energy consumption. The fluidized bed granulator suspends the material through hot air, and then sprays the liquid raw material on the suspended material to crystallize and solidify it into particles. It is suitable for granulating heat-sensitive materials. This type of device is usually used for liquid fertilizers. The spray granulator atomizes the liquid fertilizer and quickly dries and crystallizes the atomized particles in the drying tower to form solid particles. These granulation equipment can greatly improve production efficiency in fertilizer production and ensure product quality and particle uniformity. Different granulation technologies are suitable for different types of fertilizers (such as organic fertilizers, compound fertilizers, etc.). When choosing, factors such as raw material properties, output requirements and particle specifications need to be considered.

[0003] As a functional additive, manno-oligosaccharides are widely used in fertilizers and have many functions. Manno-oligosaccharides can promote the reproduction of beneficial microorganisms in the soil, especially beneficial bacteria such as actinomycetes, nitrogen-fixing bacteria and phosphate-solubilizing bacteria. These microorganisms can decompose organic matter and increase the formation of soil aggregate structure, thereby improving the aeration and water retention capacity of the soil, which is beneficial to the growth of plant roots. Manno-oligosaccharides can enhance the effectiveness of nutrients in fertilizers and promote the absorption of major nutrients such as nitrogen, phosphorus and potassium by plants. This is because it can improve the effective utilization rate of nutrients in fertilizers, reduce nutrient loss and improve the fertilizer efficiency. As a plant immune inducer, manno-oligosaccharides can stimulate the defense mechanism in plants and enhance their ability to resist diseases and pests. It can stimulate plants to produce defense substances such as antioxidant enzymes and disease-resistant proteins, reducing the risk of plant infection. Fertilizers with manno-oligosaccharides added can enhance the tolerance of plants to adverse environmental conditions (such as drought, salinity, high temperature, etc.). This is because mannan oligosaccharides can regulate the physiological state of plants, improve their metabolic function under adverse conditions, and thus enhance the plants' ability to resist stress.

[0004] When adding manno-oligosaccharides, the existing granulating device for fertilizer production cannot ensure that the manno-oligosaccharides are evenly added into the fertilizer particles, resulting in uneven manno-oligosaccharide content in the fertilizer and low granulation efficiency.

[0005] In view of the above situation, in order to overcome the above technical problems, the present invention designs a granulating device for producing special fertilizers containing manno-oligosaccharides, which solves the above technical problems. Summary of the invention

[0006] The technical purpose to be achieved by the present invention is to design a granulating device for producing special fertilizers containing manno-oligosaccharides, and to use a solution containing manno-oligosaccharides to uniformly wet the powdered fertilizer before granulation, so that the fertilizer can be quickly agglomerated and granulated.

[0007] In order to achieve the above technical objectives, the present invention provides the following technical solutions: A granulating device for producing special fertilizers containing manno-oligosaccharides has a scientific and reasonable design structure and high production efficiency and stability. The device specifically comprises a base, a granulating mechanism, a spraying component, a driving motor, a stirring mechanism and a screening component.

[0008] The base, as the foundation of the equipment, provides a stable support to ensure that the entire device will not shake or deflect during operation, thereby ensuring the smooth progress of the granulation process. The stability of the base is crucial to the overall reliability of the equipment. The granulation mechanism is installed above the base and is the core component of the device. The granulation mechanism provides a sealed space specifically for granulation operations in conjunction with the stirring mechanism. The sealed design can not only effectively prevent dust from spilling out and keep the working environment clean, but also ensure the full mixing of materials during the granulation process. The environment inside the granulation mechanism provides ideal conditions for the uniform formation of fertilizer granules, especially when containing easily dispersible additives such as manno-oligosaccharides, which can ensure its uniform distribution in the granules.

[0009] The spraying assembly is installed on the side of the granulation mechanism. Its main function is to spray the raw materials, making it easier for the powdered fertilizer raw materials to condense into granules. By evenly spraying liquid or other binders, the spraying assembly effectively solves the agglomeration problem that may occur during the granulation process, allowing the material to smoothly form uniform granules. This is especially important for functional additives such as manno-oligosaccharides, because manno-oligosaccharides need to be evenly distributed in the fertilizer granules to effectively play their role.

[0010] The drive motor is located on the side of the spray assembly and is responsible for driving the rotation of the stirring mechanism. The power and stability of the motor directly affect the efficiency of the granulation process. The drive motor is connected to the stirring mechanism, allowing the material to continue to tumble and mix in the granulation mechanism, prompting the powder raw materials to gradually aggregate into particles.

[0011] The stirring mechanism is located in the center of the granulation mechanism and is the key part of the granulation process. The stirring mechanism can not only effectively mix the materials during the rotation process, but also promote the agglomeration of the materials, so that the powdered raw materials are converted into uniform particles. At the same time, the stirring mechanism indirectly provides power to the screening component by driving the rotating shaft in the granulation mechanism to rotate.

[0012] The screening component is installed inside the granulation mechanism and is responsible for screening the fertilizer particles. After the particles are formed, the screening component outputs the qualified particles, while the unqualified particles are left in the granulation mechanism for re-forming. Through this cyclic screening method, it is ensured that each fertilizer particle meets the standard requirements and the quality of the final product is guaranteed.

[0013] The granulation mechanism is composed of a support seat, a rotating shaft, a driven gear and a granulation assembly, which has a compact structure and efficient functions. The support seat is installed above the base to provide stable support for the entire granulation mechanism and ensure that the connection between the components is firm. The rotating shaft is installed in the center of the support seat and is a crucial rotating component in the granulation process. It drives the material to stir and granulate by rotation. The driven gear is set on the surface of the rotating shaft and cooperates with the driving part to transmit power so that the rotating shaft can run stably. The granulation assembly is fixed above the support seat and directly participates in the granulation process to ensure uniform molding of the material and improve the quality of the particles.

[0014] The granulation assembly consists of a mixing sleeve, a feeding pipe, a granulation sleeve, a rotating channel and a discharge sleeve. Each component is closely connected to ensure the efficient progress of the granulation process. The mixing sleeve is installed above the support seat and is responsible for the preliminary mixing of the incoming raw materials so that the materials reach a uniform state before granulation. The feeding pipe is arranged at the top of the mixing sleeve as a channel for material input to ensure that the materials enter the mixing area smoothly. The granulation sleeve is installed on the side of the mixing sleeve, and the material starts the granulation process through here. The rotating channel is located at the outer end of the granulation sleeve, and the mixed material is further compressed and formed by the rotation. The discharge sleeve is installed on the side of the granulation sleeve to discharge the formed particles, completing the last step in the granulation process and realizing the output and separation of the materials.

[0015] The distance between the mixing sleeve and the granulation sleeve is designed to match the width of the driven teeth, thereby ensuring the precise meshing and coordinated work between the driven teeth and the active teeth. Such a design can effectively improve the transmission efficiency, enable the power to be transmitted to the granulation mechanism more smoothly, and ensure the continuity and stability of the granulation process. Through the precise matching of the active teeth and the driven teeth, the equipment can achieve higher granulation accuracy and consistency during operation. At the same time, the discharge sleeve is designed to be contracted. This structure can concentrate the output path of the particles, reduce the resistance and dispersion of the material during the discharging process, and thus greatly improve the discharging efficiency. Through this design, the particles after granulation can be discharged from the equipment more smoothly, reducing blockage or accumulation problems and improving production efficiency.

[0016] The spray assembly consists of a fixed block, a rotating hole and a nozzle, with a simple design and practical functions. The fixed block is installed on the side of the granulation mechanism to support and stabilize the spray assembly and ensure stability during the spraying process. The rotating hole is opened in the center of the fixed block, allowing the nozzle to adjust the angle as needed, making the spraying angle more flexible and ensuring that the material is sprayed evenly. The nozzle is arranged in a circular array on the inner side of the fixed block, which can evenly spray the material in multiple directions and angles to improve the spraying effect. This design can effectively ensure the uniform distribution of the sprayed liquid or binder and promote the bonding and molding of materials during the granulation process.

[0017] The stirring mechanism is composed of a stirring shaft, a spiral fan blade, a feeding component and a driving tooth. The structure is tightly designed to ensure the efficient stirring and feeding process. The stirring shaft is installed in the central position of the granulation mechanism and rotates under the action of the driving motor to drive the entire stirring process so that the materials are fully mixed. The spiral fan blade is located at one end of the stirring shaft. It is designed in a spiral shape to effectively push the material to the front of the granulation mechanism to ensure the uniform distribution and fluidity of the material during the granulation process. The feeding component is installed on the side of the spiral fan blade and is responsible for introducing external raw materials into the granulation system to ensure continuous material supply. The driving tooth is installed on the surface of the feeding component and meshes with the driven tooth to transmit power and ensure the smooth progress of the feeding process. The overall design ensures the coordination and efficient operation of the material in the stirring and feeding links, and provides a stable material flow for subsequent granulation.

[0018] The stirring mechanism also includes granulation teeth and a screening push plate, which further optimizes the granulation and screening process. The granulation teeth are arranged on the side of the feeding assembly. They are designed in a spiral shape, which can cut and disperse the material when it enters the granulation area, ensuring the uniformity of the material particles and avoiding the occurrence of agglomeration. The spiral teeth help to enhance the fluidity of the material and promote the granulation effect. The screening push plate is installed at the other end of the stirring shaft and is responsible for pushing the formed particles to the screening area. Through the action of the screening push plate, qualified particles pass the screening smoothly, and unqualified particles are returned for secondary granulation to ensure the quality of the final product and the uniformity of the particles.

[0019] The feeding assembly consists of a feeding turntable, a material storage cavity and a connecting flow channel. It is exquisitely designed and effectively improves the feeding efficiency. The feeding turntable is installed on the outside of the stirring shaft. The rotation of the stirring shaft drives the turntable to operate, ensuring that the material enters the granulation system evenly. The material storage cavity is located in the central area of ​​the feeding turntable and is used to temporarily store materials to ensure the continuity of the feeding process. The design of the cavity allows the material to enter the granulation mechanism in an appropriate amount to avoid blockage problems caused by excessive feeding. The connecting flow channel is opened between adjacent material storage cavities and is located at the outermost end of the material storage cavity. It plays a role of connection and diversion, so that the material between the material storage cavities can flow smoothly, further improving the uniformity of material distribution, and providing a continuous and stable material supply for the granulation process.

[0020] The feeding assembly also includes a connecting rod, a feeding port and a one-way valve, which further enhances the flexibility and safety of material transportation. The connecting rod is installed between the stirring shaft and the feeding turntable, and is designed as a hollow structure, which can effectively transfer the aqueous solution containing manno-oligosaccharides and maintain good fluidity. The hollow design of the connecting rod not only reduces the overall weight of the equipment, but also provides additional space for material flow, ensuring the smoothness of the conveying process. The feeding port is opened on the connecting rod, which serves as the main channel for the input of the aqueous solution of manno-oligosaccharides, ensuring that the aqueous solution of manno-oligosaccharides can smoothly enter the connecting rod and be transported to the feeding turntable. The one-way valve is set at the top of the internal cavity of the connecting rod. Its main function is to prevent the aqueous solution of manno-oligosaccharides from backflowing when no feeding is added, and to ensure the one-way flow of the aqueous solution of manno-oligosaccharides in the system. This design effectively improves the efficiency of the feeding process, reduces material waste, and maintains the stability of the system.

[0021] The screening component consists of a rotating disc, a belt groove and a screening filter. The structural design is exquisite and aims to improve the efficiency of particle screening. The rotating disc is installed at the center of the granulation mechanism. As the core part of the screening process, it is responsible for carrying and rotating the particles to be screened. Its rotation can effectively push the particles to move outward, promoting the improvement of screening efficiency. The belt groove is opened on the outer surface of the rotating disc and is designed to carry and guide the discharge of qualified particles during the screening process, ensuring that the particles can flow out smoothly while avoiding blockage. The screening filter is installed in the center of the rotating disc and has a fine aperture design. It is used to screen out unqualified particles to ensure that the quality of the final output product is uniform and meets the standards. Through this comprehensive design, the screening component can efficiently and accurately complete the particle screening task, providing a guarantee for subsequent production processes.

[0022] The beneficial effects of the present invention are as follows: 1. The present invention significantly improves the work efficiency and product quality in the mixed fertilizer production process by setting a granulation mechanism. Specifically, uniform addition of manno-oligosaccharides: During the stirring and granulation process, the use of a stirring mechanism can effectively mix the powdered mixed fertilizer, and the uniform addition of manno-oligosaccharides can be achieved by rotating the feeding component. The action of centrifugal force enables manno-oligosaccharides to be evenly distributed throughout the material, ensuring that each fertilizer particle contains sufficient manno-oligosaccharides, thereby enhancing the functionality and effect of the fertilizer. The rotation of the rotating shaft is achieved by the cooperation of the active teeth and the driven teeth, ensuring the effective transmission of power. This design reduces mechanical friction, improves the utilization rate of power, makes the cooperation between the various components closer, and runs more smoothly. The rotating shaft drives the movement of the belt, which further drives the rotation of the screening component. This design not only improves the screening speed, but also ensures the effective separation of qualified particles from unqualified particles. By using a push rod, the screening process can be controlled more accurately, improving the screening efficiency of the product.

[0023] 2. The overall design of the present invention enables coordinated operation between various components, reduces the time of material processing, and improves the work efficiency of the production line. The automated workflow enables the equipment to complete more granulation and screening tasks in a short time, meeting the needs of large-scale production. The quality of the final product is guaranteed by the uniform addition of manno-oligosaccharides and the efficient screening process. The evenly distributed manno-oligosaccharides not only improve the nutritional value of the fertilizer, but also increase its utilization rate in the soil, thereby promoting the healthy growth of plants. The automated design reduces the need for manual intervention, thereby saving labor costs. At the same time, the efficient operation process also reduces the waste of raw materials, promotes the efficient use of resources, and provides support for sustainable development.

DETAILED DESCRIPTION

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] like Figure 1-8As shown, a granulating device for producing special fertilizers containing manno-oligosaccharides has a scientific and reasonable design structure and high production efficiency and stability. It specifically includes a base 1, a granulating mechanism 2, a spraying component 3, a driving motor 4, a stirring mechanism 5 and a screening component 6.

[0029] The base 1 serves as the foundation of the equipment and provides a stable support to ensure that the entire device will not shake or deflect during operation, thereby ensuring the smooth progress of the granulation process. The stability of the base 1 is crucial to the overall reliability of the equipment. The granulation mechanism 2 is installed above the base 1 and is the core component of the device. The granulation mechanism 2 provides a sealed space specifically used for granulation operations in conjunction with the stirring mechanism 5. The sealed design can not only effectively prevent dust from spilling out and keep the working environment clean, but also ensure sufficient mixing of materials during the granulation process. The environment inside the granulation mechanism 2 provides ideal conditions for the uniform molding of fertilizer particles, especially when containing easily dispersible additives such as mannooligosaccharides, it can ensure its uniform distribution in the particles.

[0030] The spraying assembly 3 is installed on the side of the granulation mechanism 2. Its main function is to spray the raw materials so that the powdered fertilizer raw materials can be more easily condensed into particles. By evenly spraying liquid or other binders, the spraying assembly 3 effectively solves the agglomeration problem that may occur during the particle granulation process, so that the material can smoothly form uniform particles. This is especially important for functional additives such as manno-oligosaccharides, because manno-oligosaccharides need to be evenly distributed in the fertilizer particles to effectively play their role.

[0031] The drive motor 4 is located on the side of the spraying assembly 3 and is responsible for driving the rotation of the stirring mechanism 5. The power and stability of the motor directly affect the efficiency of the granulation process. The drive motor 4 is connected to the stirring mechanism 5, so that the material can be continuously tumbled and mixed in the granulation mechanism 2, so that the powder raw materials are gradually aggregated into particles.

[0032] The stirring mechanism 5 is located in the center of the granulating mechanism 2 and is a key part of the granulating process. The stirring mechanism 5 can not only effectively mix the materials during the rotation process, but also promote the agglomeration of the materials, so that the powdered raw materials are converted into uniform particles. At the same time, the stirring mechanism 5 indirectly provides power to the screening component 6 by driving the rotating shaft 22 in the granulating mechanism 2 to rotate.

[0033] The screening component 6 is installed inside the granulation mechanism 2 and is responsible for screening the fertilizer particles. After the particles are formed, the screening component 6 outputs the qualified particles, while the unqualified particles are left in the granulation mechanism 2 for re-forming. Through this cyclic screening method, it is ensured that each fertilizer particle meets the standard requirements and the quality of the final product is guaranteed.

[0034] like Figure 3As shown, the granulation mechanism 2 is composed of a support seat 21, a rotating shaft 22, a driven tooth 23 and a granulation assembly 24, which has a compact structure and efficient functions. The support seat 21 is installed above the base 1 to provide stable support for the entire granulation mechanism 2 and ensure that the connection between the various components is firm. The rotating shaft 22 is installed in the center of the support seat 21. It is a crucial rotating component in the granulation process. It drives the material to be stirred and granulated by rotation. The driven tooth 23 is arranged on the surface of the rotating shaft 22 and cooperates with the driving part to transmit power so that the rotating shaft 22 can run stably. The granulation assembly 24 is fixed above the support seat 21 and directly participates in the granulation process to ensure that the material is evenly formed and the quality of the particles is improved.

[0035] like Figure 4 As shown, the granulation assembly 24 is composed of a mixing sleeve 241, a feeding pipe 242, a granulation sleeve 243, a rotating channel 244 and a discharging sleeve 245. Each component is closely connected to ensure the efficient progress of the granulation process. The mixing sleeve 241 is installed above the support seat 21 and is responsible for the preliminary mixing of the incoming raw materials so that the materials reach a uniform state before granulation. The feeding pipe 242 is arranged at the top of the mixing sleeve 241 as a channel for material input to ensure that the materials enter the mixing area smoothly. The granulation sleeve 243 is installed on the side of the mixing sleeve 241, and the material starts the granulation process through here. The rotating channel 244 is located at the outer end of the granulation sleeve 243, and the mixed material is further compressed and formed by the rotation. The discharging sleeve 245 is installed on the side of the granulation sleeve 243 to discharge the formed particles, complete the last step in the granulation process, and realize the output and separation of the materials.

[0036] The distance between the mixing sleeve 241 and the granulation sleeve 243 is designed to match the width of the driven teeth 23, so as to ensure the precise meshing and coordinated work between the driven teeth 23 and the active teeth 54. Such a design can effectively improve the transmission efficiency, so that the power can be transmitted to the granulation mechanism 2 more smoothly, and the continuity and stability of the granulation process can be ensured. Through the precise matching of the active teeth 54 and the driven teeth 23, the equipment can achieve higher granulation accuracy and consistency during operation. At the same time, the discharge sleeve 245 is designed to be contracted. This structure can concentrate the output path of the particles, reduce the resistance and dispersion of the material during the discharge process, and thus greatly improve the discharge efficiency. Through this design, the particles after granulation can be discharged from the equipment more smoothly, reducing blockage or accumulation problems and improving production efficiency.

[0037] like Figure 5As shown, the spray assembly 3 is composed of a fixed block 31, a rotating hole 32 and a nozzle 33, and has a simple design and practical functions. The fixed block 31 is installed on the side of the granulation mechanism 2, and plays a role in supporting and stabilizing the spray assembly 3, ensuring stability during the spraying process. The rotating hole 32 is opened in the center of the fixed block 31, allowing the nozzle 33 to adjust the angle as needed, making the spraying angle more flexible and ensuring that the material is sprayed evenly. The nozzle 33 is arranged on the inner side of the fixed block 31 in a circular array, which can evenly spray the material in multiple directions and angles to improve the spraying effect. This design can effectively ensure the uniform distribution of the sprayed liquid or binder, and promote the bonding and molding of materials during the granulation process.

[0038] like Figure 6 As shown, the stirring mechanism 5 is composed of a stirring shaft 51, a spiral blade 52, a feeding assembly 53 and a driving tooth 54, and the structural design is compact to ensure the efficient progress of the stirring and feeding process. The stirring shaft 51 is installed in the central position of the granulation mechanism 2, and rotates under the action of the drive motor 4, driving the entire stirring process to fully mix the materials. The spiral blade 52 is located at one end of the stirring shaft 51, and is designed to be spiral, which effectively pushes the material to the front of the granulation mechanism 2 to ensure the uniform distribution and fluidity of the material during the granulation process. The feeding assembly 53 is installed on the side of the spiral blade 52, which is responsible for introducing external raw materials into the granulation system to ensure continuous material supply. The driving tooth 54 is installed on the surface of the feeding assembly 53, meshing with the driven tooth 23, transmitting power and ensuring the smooth progress of the feeding process. The overall design ensures the coordination and efficient operation of the material in the stirring and feeding links, and provides a stable material flow for subsequent granulation.

[0039] The stirring mechanism 5 also includes a granulation tooth 55 and a screening push plate 56, which further optimizes the granulation and screening process. The granulation tooth 55 is arranged on the side of the feeding component 53, and is designed to be spiral, which can cut and disperse the material when it enters the granulation area, ensuring the uniformity of the material particles and avoiding the occurrence of agglomeration. The spiral tooth helps to enhance the fluidity of the material and promote the granulation effect. The screening push plate 56 is installed at the other end of the stirring shaft 51, which is responsible for pushing the formed particles to the screening area. Through the action of the screening push plate 56, qualified particles pass the screening smoothly, and unqualified particles are returned for secondary granulation, ensuring the quality of the final product and the uniformity of the particles.

[0040] like Figure 7As shown, the feeding assembly 53 is composed of a feeding turntable 531, a material storage cavity 532 and a connecting flow channel 533, which is exquisitely designed and effectively improves the feeding efficiency. The feeding turntable 531 is installed on the outside of the stirring shaft 51, and the rotation of the stirring shaft 51 drives the turntable to operate, ensuring that the material enters the granulation system evenly. The material storage cavity 532 is located in the central area of ​​the feeding turntable 531, which is used to temporarily store materials to ensure the continuity of the feeding process. The design of the cavity allows the material to enter the granulation mechanism 2 in an appropriate amount to avoid blockage caused by excessive feeding. The connecting flow channel 533 is opened between adjacent material storage cavities 532, located at the outermost end of the material storage cavity 532, and plays a role in connection and diversion, so that the material between each material storage cavity 532 can flow smoothly, further improving the uniformity of material distribution, and providing a continuous and stable material supply for the granulation process.

[0041] The feeding assembly 53 also includes a connecting rod 534, a feeding port 535 and a one-way valve 536, which further enhances the flexibility and safety of material transportation. The connecting rod 534 is installed between the stirring shaft 51 and the feeding turntable 531, and is designed as a hollow structure, which can effectively transfer the aqueous solution containing manno-oligosaccharides and maintain good fluidity. The hollow design of the connecting rod 534 not only reduces the overall weight of the equipment, but also provides additional space for material flow, ensuring the smoothness of the conveying process. The feeding port 535 is opened on the connecting rod 534, as the main channel for the input of the aqueous solution of manno-oligosaccharides, ensuring that the aqueous solution of manno-oligosaccharides can smoothly enter the connecting rod 534 and be transported to the feeding turntable 531. The one-way valve 536 is arranged at the uppermost end of the internal cavity of the connecting rod 534, and its main function is to prevent the aqueous solution of manno-oligosaccharides from flowing back when no feeding is added, and to ensure the one-way flow of the aqueous solution of manno-oligosaccharides in the system. This design effectively improves the efficiency of the feeding process, reduces material waste, and maintains the stability of the system.

[0042] like Figure 8 As shown, the screening component 6 is composed of a rotating disk 61, a belt groove 62 and a screening filter 63, and the structural design is exquisite, aiming to improve the efficiency of particle screening. The rotating disk 61 is installed at the center of the granulation mechanism 2. As the core part of the screening process, it is responsible for carrying and rotating the particles to be screened. Its rotation can effectively push the particles to move outward, promoting the improvement of screening efficiency. The belt groove 62 is opened on the outer surface of the rotating disk 61, and is designed to carry and guide the discharge of qualified particles during the screening process, ensuring that the particles can flow out smoothly while avoiding the occurrence of blockage. The screening filter 63 is installed in the center of the rotating disk 61, with a fine aperture design, which is used to screen out unqualified particles to ensure that the quality of the final output product is uniform and meets the standards. Through this comprehensive design, the screening component 6 can efficiently and accurately complete the particle screening task, providing a guarantee for the subsequent production process.

[0043] During the working process of the present invention, a variety of powdered fertilizers enter the interior of the mixing sleeve 241 through the feeding pipe 242, and the nozzle 33 sprays water or adhesive solution thereon. The stirring shaft 51 rotates under the drive of the driving motor 4, and the spiral blades thereon push the mixed fertilizer powder forward, and the feeding assembly 53 rotates under the drive of the stirring shaft 51; Before the granulation work, the staff puts the aqueous solution containing manno-oligosaccharides and other substances into the storage cavity 532. When the feeding turntable 531 is driven by the stirring shaft 51 to rotate, the aqueous solution in the storage cavity 532 moves outward under the action of centrifugal force. Since the connecting channel 533 is arranged at the outermost end of the storage cavity 532, the aqueous solution will enter the connecting channel 535 and the one-way valve 536 in turn and then gather in the cavity of the connecting rod 534. Since the one-way valve 536 only allows the aqueous solution to enter the connecting rod 534 from the connecting channel 533, the aqueous solution in the connecting rod 534 will gradually increase and be discharged through the feeding port 535. As the stirring shaft 51 rotates, more and more aqueous solutions stored in the storage cavity 532 will enter the mixing sleeve 241 in one direction, thereby achieving the effect of evenly adding manno-oligosaccharides to the fertilizer. The fertilizer mixed with the manno-oligosaccharide aqueous solution enters the granulation sleeve 243, and the granulation teeth 55 rotate to make the materials rub against each other and gather in the sleeve, and finally form granules. The fertilizer granules are pushed toward the filter screen by the push rod, and the qualified fertilizer granules are discharged through the discharge sleeve 245, and the unqualified ones continue to be granulated; When the feeding turntable 531 rotates, the driving teeth 54 and the driven teeth 23 arranged on its surface mesh and rotate, thereby driving the rotating shaft 22 to rotate. The rotating shaft 22 and the rotating disk 61 are connected by a belt, so that the screening filter 63 also keeps rotating during the screening process, thereby improving the screening efficiency.
