Description

Technical Field

[0001] This invention relates to the field of compound fertilizer production equipment technology, and in particular to a centrifugal granulation tower for producing glycoside-containing compound fertilizer. Background Technology

[0002] Compound fertilizers are a type of chemical fertilizer produced through chemical synthesis or physical mixing processes. They contain two or more of the three essential nutrients for crops: nitrogen (N), phosphorus (P), and potassium (K), and are one of the core fertilizer types in agricultural production. They are primarily in granular form, with some being powders or liquids, and offer significant advantages such as balanced nutrient supply, convenient application, and stable efficacy. The core value of compound fertilizers lies in the synergistic supply of multiple nutrients, simultaneously meeting the needs of crops for various nutrients, avoiding nutrient imbalances caused by single-nutrient application, and significantly improving planting efficiency. In agricultural production, they serve as both base fertilizer and some top dressing, playing a crucial role in increasing crop yield, optimizing agricultural product quality, and ensuring food security.

[0003] Glycoside-containing compound fertilizers are a new type of high-efficiency fertilizer. Their glycoside components promote nutrient absorption by crops and enhance fertilization effects, leading to their increasingly widespread application in agricultural production. However, the granulation process is crucial to product quality in the production of glycoside-containing compound fertilizers. Existing granulation equipment generally suffers from numerous technical defects, making it difficult to meet the production requirements of glycoside-containing compound fertilizers. Current granulation equipment for glycoside-containing compound fertilizer production suffers from uneven raw material mixing, resulting in significant differences in fertilizer particle size. This not only affects the uniformity of the product's appearance but also causes inconsistent fertilizer dissolution rates, reducing fertilization effectiveness. Therefore, this paper proposes to develop a centrifugal granulation tower for the production of glycoside-containing compound fertilizers. Summary of the Invention

The centrifugal discharge assembly is installed at the bottom of the centrifugal mixing assembly to receive the mixed glycoside compound fertilizer discharged from the centrifugal mixing assembly; The drive assembly is mounted on the top of the cross support frame and fixedly connected to the side wall of the centrifugal mixing assembly, and is used to drive the centrifugal mixing assembly to rotate to generate uniform centrifugal force; Multiple sets of transmission components are symmetrically arranged about the center of the centrifugal mixing component, mesh with the drive component, and serve to limit the top of the drive component and help disperse the force on the drive component. The servo motor is mounted on the top of the cross support frame, and the output shaft of the servo motor is connected to a set of transmission components via a coupling.

[0007] As a further improvement to the above solution, the centrifugal mixing assembly includes a mixing tank and a discharge nozzle; the inner wall of the mixing tank is inclined with multiple sets of centrally symmetrical stirring blades, which can drive the stirring blades to rotate synchronously when the mixing tank rotates, thus mixing the glycoside-containing compound fertilizer raw materials entering the mixing tank; the side wall of the mixing tank is provided with multiple sets of centrally symmetrical U-shaped clamps for precise docking and fixed connection with the top of the drive assembly; the lower outer wall of the mixing tank is provided with a connecting flange for positioning and installing the centrifugal discharge assembly; the discharge nozzle is threadedly installed in the middle of the bottom of the mixing tank and communicates with the inner cavity of the mixing tank, so that the uniformly mixed glycoside-containing compound fertilizer inside the mixing tank can be slowly and stably discharged into the inner cavity of the centrifugal discharge assembly through the discharge nozzle.

[0008] As a further improvement to the above solution, the centrifugal discharge assembly includes a discharge box; the top of the discharge box is provided with a fixing flange that matches the connecting flange, which facilitates the positioning, installation, and disassembly of the centrifugal discharge assembly and the centrifugal mixing assembly; the side wall of the discharge box is evenly provided with multiple discharge holes, and the mixed glycoside-containing compound fertilizer that enters the discharge box can be discharged through the discharge holes under the action of centrifugal force; a conical distribution block is provided in the middle of the bottom of the discharge box, which can evenly guide the mixed glycoside-containing compound fertilizer falling through the discharge nozzle to the surrounding area of ​​the discharge box.

[0009] As a further improvement to the above solution, the drive assembly includes an annular support base and a drive ring; the top of the annular support base and the bottom of the drive ring are both raised annular structures, and the top of the drive ring is a bevel gear structure; matching annular grooves are provided on the raised annular structures of the annular support base and the drive ring; multiple balls are installed in the annular grooves to convert the sliding friction between the drive ring and the annular support base into rolling friction; a U-shaped insert matching a U-shaped sleeve is provided on the top of the drive ring, and inserting the U-shaped insert into the inner cavity of the U-shaped sleeve allows the mixing barrel to rotate synchronously when the drive ring rotates.

[0010] As a further improvement to the above solution, the cross-section of the annular groove is semi-circular, and the radius is adapted to the radius of the ball; the number of U-shaped inserts is consistent with the number of U-shaped sleeves, and the U-shaped inserts and U-shaped sleeves are fixed and locked together by bolts.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention adopts a "stirring + centrifugation" granulation mode. Through the coordinated operation of the centrifugal mixing component and the centrifugal discharging component, the stirring blades are designed with an inclination to achieve full tumbling and mixing of raw materials without any dead corners. The material distribution block can evenly guide the raw materials to each discharge hole. Combined with the stepless adjustment of centrifugal force by the servo motor, it effectively solves the defect of uneven particle size in existing equipment, ensuring that the glycoside compound fertilizer particles are regular and the composition is uniform, thereby improving product quality and fertilization effect. This invention uses multiple sets of adjustable cooling fans and adjustable air intake louvers to flexibly adjust the cooling wind speed and air intake volume according to the outside temperature and production needs, ensuring that the granules are cooled quickly and evenly after granulation, avoiding granule clumping and breakage, and improving product storage stability. The parameters of each component of the equipment of this invention can be flexibly adapted according to the production capacity, and the discharge hole diameter can be replaced to adapt to the production of glycoside compound fertilizer with different particle size requirements.

[0018] To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of known functions and known components are omitted.

[0019] Please combine Figure 1-10As shown in the figure, an embodiment of the present invention provides a centrifugal granulation tower for the production of glycoside-containing compound fertilizer, including a tower body 1, a centrifugal production mechanism 2, a feeding pipe 3, a cooling fan 4, an air inlet louver 5, and a receiving tray 6. In the prior art, granulation equipment used for the production of glycoside-containing compound fertilizers generally suffers from uneven mixing of raw materials during the granulation process, resulting in large differences in fertilizer particle size. This not only affects the regularity of the product appearance but also causes inconsistent fertilizer dissolution rates, reducing the fertilization effect. To solve the above technical problems, the present invention optimizes the overall structural design to achieve integrated operation of uniform raw material mixing, precise centrifugal granulation, and rapid and uniform cooling. Among them, the tower body 1 serves as the main supporting structure of the equipment. The height of tower body 1 can be adapted to 8-15m according to the actual production capacity (5-20t / h), with an inner diameter of 3-6m. Its inner cavity sidewalls are polished to prevent compound fertilizer granules from sticking together. The centrifugal production mechanism 2 is fixed inside the tower body 1 at the top (1.5-2m from the top of the tower) using high-strength bolts. This position ensures sufficient cooling space for the centrifuged granules, enabling efficient mixing and precise granulation of the glycoside-containing compound fertilizer. The feed pipe 3, made of wear-resistant stainless steel, is inlaid on the side wall of the tower body 1. The output end of the feed pipe 3 extends into the interior of the centrifugal production mechanism 2 and precisely connects to the inlet of the centrifugal mixing component. The input end of the feed pipe 3... It can be connected to an external feed pump to stably deliver glycoside-containing compound fertilizer raw materials to the centrifugal production mechanism 2; multiple sets (4-8 sets, adapted according to the inner diameter of the tower) of cooling fans 4 are evenly fixed on the inner wall of the tower body 1. The cooling fans 4 are axial flow fans with a rated power of 1.5-3kW and the wind speed can be adjusted in stages (1-3m / s) to quickly and uniformly cool the glycoside-containing compound fertilizer granules centrifuged out by the centrifugal production mechanism 2, effectively ensuring the granule forming effect and preventing the granules from sticking or deforming due to untimely cooling; the air inlet louvers 5 are embedded in the side wall of the tower body 1 and are located below the cooling fans 4 (spacing 0.8-1.2m). The air intake louver 5 adopts an adjustable structure, and its louver angle can be flexibly adjusted according to the outside temperature and cooling requirements. The inner end of the air intake louver 5 is connected to the rear side of the cooling fan 4 through a high-temperature and corrosion-resistant hose to introduce clean cold air from the outside, providing a stable cooling air source for the cooling fan 4. At the same time, the louver structure can effectively prevent external dust and debris from entering the tower body and contaminating the fertilizer. The receiving tray 6 is fixed to the lower part of the inner cavity of the tower body 1 with bolts. The receiving tray 6 adopts a funnel-shaped structure, and its inner wall is treated with an anti-stick coating. The bottom of the funnel is equipped with a discharge port and a control valve to collect the cooled and formed glycoside compound fertilizer granules. At the same time, the discharge speed can be controlled to facilitate subsequent packaging operations. The centrifugal production mechanism 2, as the core component of this invention, is responsible for the mixing and granulation of the glycoside-containing compound fertilizer; for example... Figure 3-4As shown, it includes a cross support frame 21, a centrifugal mixing assembly 22, a centrifugal discharging assembly 23, a drive assembly 24, a transmission assembly 25, and a servo motor 26. The cross support frame 21 is made of high-strength alloy steel, and its ends are symmetrically fixed to the inner wall of the tower body 1 by high-strength bolts. The cross support frame 21 is kept horizontal. A circular slot matching the centrifugal mixing assembly 22 is provided in the middle of the cross support frame 21 for its installation. Reinforcing ribs are provided at the bottom of the cross support frame 21 to improve its overall load-bearing capacity and stably support the weight of the centrifugal mixing assembly, drive assembly, and other components. The component 22 is vertically rotatably installed inside the circular slot of the cross support frame 21, and the bottom end of the feeding pipe 3 extends into the inner cavity of the centrifugal mixing component 22, with the inlet facing the mixing area. This is used to accurately receive the glycoside-containing compound fertilizer raw materials conveyed by the feeding pipe 3, preventing raw material spillage. The centrifugal discharge component 23 is fixed to the bottom of the centrifugal mixing component 22 with bolts, and a sealing gasket is set at the connection between the two to ensure sealing performance and prevent raw material leakage. This is used to stably receive the uniformly mixed glycoside-containing compound fertilizer discharged from the centrifugal mixing component 22. The drive component 24 is fixed to the top of the cross support frame 21 with bolts, and the top of the drive component 24 is connected to the centrifugal mixing component 22 with bolts. The side wall of component 22 is fixedly connected, and the connection position adopts an anti-loosening design. It is used to drive the centrifugal mixing component 22 to rotate stably to generate uniform centrifugal force. The magnitude of the centrifugal force can be adjusted by a subsequent servo motor. Multiple sets (preferably 4 sets) of transmission components 25 are fixed to the top of the cross support frame 21 with bolts. The multiple sets of transmission components 25 are centrally symmetrical about the axis of the centrifugal mixing component 22. The transmission components 25 are precisely engaged with the drive component 24, which not only limits the top of the drive component 24, but also helps to distribute the force on the drive component 24, ensuring the stability and smoothness of the rotation of the drive component 24 and avoiding problems such as offset and jamming. The servo motor 26 is fixed to the top of the cross support frame 21 by bolts. The servo motor 26 is a high-precision variable frequency servo motor with a rated power of 5-10kW and a speed that can be steplessly adjusted within the range of 0-1500r / min. Its output shaft is connected to the shaft of one of the transmission components 25 through a flexible coupling. The flexible coupling can effectively buffer the impact force during rotation and protect the motor and transmission components. By controlling the speed of the servo motor 26, the drive component 24 is smoothly driven to rotate through the transmission component 25, which in turn drives the centrifugal mixing component 22 to rotate, thereby achieving precise control of centrifugal force and adapting to the production of glycoside compound fertilizer with different particle size requirements. The centrifugal mixing component 22 is used to fully mix the raw materials of glycoside-containing compound fertilizer, laying the foundation for subsequent uniform granulation; such as Figure 5-6As shown, it includes a mixing tank 221 and a discharge nozzle 225. The mixing tank 221 is made of stainless steel with a polished, non-stick inner wall. Its inner diameter is 800-1200mm and its height is 600-800mm, which can be flexibly adapted according to production capacity (the outer diameter of the mixing tank 221 is smaller than the inner diameter of the circular slot on the cross support frame 21). The inner wall of the mixing tank 221 has multiple sets (3-6 sets) of stirring blades 222 welded at an angle. The inclination angle of the stirring blades 222 is set to 30°-45°. This angle can generate an upward lift when the mixing tank rotates, so that the raw materials are fully turned. The mixing drum 221 is equipped with multiple sets of stirring blades 222 arranged symmetrically about the axis of the mixing drum 221 to ensure uniform mixing and eliminate dead zones. When the mixing drum 221 rotates, it drives the stirring blades 222 to rotate synchronously. The rotating stirring blades 222 thoroughly mix the glycoside-containing compound fertilizer raw materials (glycoside components, base fertilizer, binder, etc.) entering the mixing drum 221, ensuring uniform distribution of each component and avoiding differences in particle composition due to uneven mixing of raw materials. The side wall of the mixing drum 221 is welded with multiple (preferably 4) interconnected U-shaped clamps 223, and multiple sets of... The U-shaped clamp 223 is centrally symmetrically arranged about the axis of the mixing tank 221, and is used for precise docking and fixed connection with the top of the drive assembly 24. The connection position is locked with bolts to ensure stable power transmission and prevent slippage. A connecting flange 224 is welded to the outer wall of the lower side of the mixing tank 221. The connecting flange 224 adopts a sealing structure and has a sealing groove on its surface for precise positioning and installation of the centrifugal discharge assembly 23, ensuring the sealing and stability of the connection between the centrifugal discharge assembly 23 and the mixing tank 221, and preventing leakage of raw materials during the falling process. The discharge nozzle 225 is connected by a screw... The discharge nozzle 225 is installed at the bottom center of the mixing tank 221. The inner diameter of the discharge nozzle 225 is 50-80mm, and the discharge nozzle 225 is connected to the inner cavity of the mixing tank 221. An adjustable throttle valve is installed inside the discharge nozzle 225, which can adjust the raw material discharge speed according to the mixing speed and granulation requirements. This allows the uniformly mixed glycoside compound fertilizer inside the mixing tank 221 to be slowly and stably discharged into the inner cavity of the centrifugal discharge component 23 through the discharge nozzle 225. This avoids the raw material from being discharged too quickly, which would cause the raw material to accumulate in the discharge box and affect the uniformity of subsequent granulation. At the same time, it can also prevent the raw material from overflowing from the mixing tank due to being discharged too slowly. Centrifugal discharge assembly 23 is a key component for achieving the granulation of glycoside-containing compound fertilizer; such as Figure 7-8As shown, it includes a discharge box 231; the discharge box 231 is made of stainless steel, with a polished and non-stick inner wall to prevent compound fertilizer granules from sticking together. Its inner diameter is compatible with the inner diameter of the mixing tank 221 (750-1150mm), and its height is 300-400mm to ensure stable reception of raw materials discharged from the discharge nozzle 225; a fixing flange 232 matching the connecting flange 224 is welded to the top of the discharge box 231. The fixing flange 232 and the connecting flange 224 have the same dimensions. The connecting flange 224 and the fixing flange 232 are fixedly connected by high-strength bolts, and a high-temperature resistant sealing gasket is set at the connection point. This not only facilitates the positioning, installation, disassembly, and subsequent maintenance of the centrifugal discharge assembly 23 and the centrifugal mixing assembly 22, but also effectively prevents raw material leakage; multiple discharge holes 233 are evenly opened on the side wall of the discharge box 231. The hole diameter is designed to be 2-5mm according to the required particle size. Different discharge boxes with different hole diameters can be replaced according to actual production needs. The 33 holes are evenly distributed in a ring. The mixed glycoside-containing compound fertilizer that enters the discharge box 231 can be quickly discharged through the discharge holes 233 under the action of centrifugal force. After discharge, it naturally forms into regular granules under the action of gravity and cooling airflow. The uniform arrangement of the discharge holes 233 can effectively ensure the consistency of particle size and avoid the mixing of large and small particles. The bottom center of the discharge box 231 has a raised distribution block 234. The distribution block 234 adopts a conical structure with rounded corners at the top. The material is the same as the discharge box. The raised conical distribution block 234 can quickly and evenly guide the mixed glycoside-containing compound fertilizer that falls vertically through the discharge nozzle 225 to the periphery of the discharge box 231, ensuring that the discharge amount of each discharge hole 233 is uniform. This avoids the situation where some discharge holes are blocked due to excessive raw materials or some discharge holes have no discharge due to insufficient raw materials, further improving the uniformity of particle size. At the same time, the distribution block 234 can also reduce the accumulation of raw materials at the bottom of the discharge box and ensure smooth discharge.

[0020] Drive assembly 24 provides stable power to centrifugal mixing assembly 22 and centrifugal discharging assembly 23, ensuring that they rotate synchronously and generate uniform centrifugal force; such as Figure 9As shown, it includes an annular support 241 and a drive ring 242. The annular support 241 is fixed to the top of the cross support frame 21 by high-strength bolts. The inner diameter of the annular support 241 matches the outer diameter of the drive ring 242 to stably support the drive ring 242. The top of the annular support 241 and the bottom of the drive ring 242 are both raised annular structures. The top of the drive ring 242 is a bevel gear structure to ensure precise meshing with the bevel gear of the transmission assembly 25 and achieve smooth power transmission. Matching annular grooves 243 are provided on the annular structure at the top of the annular support 241 and the annular structure at the bottom of the drive ring 242. The cross-section of the annular groove 243 is semi-circular, and the radius matches the radius of the ball bearing 244 for installing the ball bearing 244. Multiple (40-80) ball bearings 244 are installed inside the annular groove 243. The ball bearings 244 are made of high-strength materials. Wear-resistant balls with rust-proof surface treatment are evenly distributed among the balls 244. They are used to convert the sliding friction between the drive ring 242 and the annular support 241 into rolling friction, which greatly reduces the rotational wear between the two, extends the service life of the components, and reduces rotational resistance. This ensures the smoothness and stability of the drive ring 242's rotation and avoids problems such as jamming and deviation. The top of the drive ring 242 is welded with U-shaped inserts 245 that match the U-shaped sleeve 223. The number of U-shaped inserts 245 is the same as that of the U-shaped sleeve 223. They are made of thickened stainless steel. The U-shaped inserts 245 are precisely inserted into the inner cavity of the U-shaped sleeve 223 and the two are fixed and locked with bolts to ensure a firm connection. This allows the drive ring 242 to rotate synchronously, driving the mixing tank 221 to rotate, and then driving the centrifugal discharge assembly 23 to rotate synchronously, achieving stable power transmission and avoiding power loss or slippage. The transmission assembly 25 is used to transmit the power of the servo motor 26 to the drive assembly 24, thereby reducing and reversing the power, and ensuring the smooth rotation of the drive ring 242; for example Figure 10As shown, it includes a U-shaped support 251, a drive shaft 253, and a drive bevel gear 254. The U-shaped support 251 is fixed to the top of the cross support frame 21 by bolts. A wear-resistant bearing 252 is embedded in the top of the U-shaped support 251. The wear-resistant bearing 252 is a deep groove ball bearing, and its model is adapted to the diameter of the drive shaft 253. It is used to provide stable support for the drive shaft 253, reduce wear during rotation, extend the service life of the drive shaft, and ensure smooth rotation of the drive shaft 253. The drive shaft 253 is horizontally inserted into the inner cavity of the wear-resistant bearing 252. The drive shaft 253 is made of high-strength stainless steel, with a diameter of 30-50mm, and its surface is polished to ensure smooth rotation of the drive shaft 253 without jamming. A bevel gear 254 is fitted onto one end of the drive shaft 253. The drive bevel gear 254 and the drive shaft 253 are fixed together by a key to prevent slippage. The drive bevel gear 254 and the bevel tooth structure on the top of the drive ring 242 mesh precisely with each other, with the meshing gap controlled at 0.1-0.2mm, to achieve smooth power transmission and deceleration and steering. This converts the high-speed rotation of the servo motor 26 into the low-speed, high-torque rotation of the drive ring 242, meeting the power requirements of centrifugal granulation. One end of the drive shaft 253 away from the drive bevel gear 254 is connected to the output shaft of the servo motor 26 through a flexible coupling. The flexible coupling can effectively buffer the impact and vibration during rotation, protecting the servo motor 26 and the drive shaft 253 and preventing damage to components due to vibration. When the servo motor 26 starts and rotates, it drives the transmission shaft 253 to rotate synchronously. The transmission shaft 253 drives the transmission bevel gear 254 on it to rotate. The transmission bevel gear 254 meshes with the bevel gear at the top of the drive ring 242, thereby driving the drive ring 242 to rotate smoothly. The drive ring 242 drives the mixing tank 221 to rotate through the connection between the U-shaped insert and the U-shaped sleeve. The mixing tank 221 then drives the stirring blades 222 and the centrifugal discharge assembly 23 at the bottom to rotate synchronously. The rotation of the stirring blades 222 achieves full mixing of the glycoside-containing compound fertilizer raw materials inside the mixing tank 221, ensuring that each component is evenly distributed. The uniform centrifugal force generated by the rotation of the centrifugal discharge assembly 23 causes the mixed glycoside-containing compound fertilizer inside the discharge box 231 to be quickly discharged through the evenly distributed discharge holes 233 and form regular and uniform particles. During the falling process, the particles are quickly cooled by the cold air blown out by the cooling fan 4 and finally fall into the collection tray 6 for collection.

[0021] This invention, through the synergistic cooperation of the above-mentioned structures, completely solves the technical problems of uneven particle size, poor cooling effect, and poor product quality in the granulation of glycoside compound fertilizers in the prior art, greatly improving the production quality and efficiency of glycoside compound fertilizers. Moreover, the equipment has a reasonable structure, is easy to operate, has low maintenance costs, and is suitable for production needs of different capacities.

[0022] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
