[0002] Alginic acid compound fertilizer is a type of fertilizer in which natural alginic acid synergists are added to the compound fertilizer production process. It contains a certain amount of alginic acid, which is typically extracted using advanced fermentation technology to maintain its biological activity. Compared to conventional compound fertilizers, alginic acid compound fertilizer has higher utilization rates, better environmental friendliness, and reduces ammonia volatilization losses.
[0003] For example, CN222789157U discloses a high-tower granulation device for alginate compound fertilizer, relating to the field of compound fertilizer production technology. This utility model includes a high-tower body, a top cover, an air outlet sleeve, and a fan housing. The fan housing is located on one side of the high-tower body, the top cover is fixed to the top of the high-tower body, and the air outlet sleeve is fixedly connected to the bottom of the high-tower body. Spiral blades are fixed in a ring array on the inner wall of the air outlet sleeve, and an inner fixing column is fixed to the side of all spiral blades closest to the central axis of the air outlet sleeve. This utility model, by setting up a high-tower body, top cover, air outlet sleeve, and fan housing, solves the problems of secondary cooling of fertilizer granules affecting production efficiency in high-tower production of alginate compound fertilizer, and the heat released during the cooling of fertilizer droplets easily causing the high-tower temperature to rise, affecting subsequent fertilizer granulation efficiency.
[0004] However, in the existing technology, the uniformity and stability of particle size are key factors affecting the quality of compound fertilizers during the falling granulation process of high tower granulation equipment. Currently, traditional equipment cannot control the impact speed of material falling, resulting in uneven particle size and thus limiting the practicality of the equipment. Utility Model Content
[0005] The purpose of this invention is to solve the problem that in the existing high-tower granulation equipment, the uniformity and stability of particle size are key factors affecting the quality of compound fertilizer during the falling granulation process. However, the current traditional equipment cannot control the impact speed of the falling material, resulting in uneven particle size.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-tower granulation device for compound fertilizer production, comprising a first high-tower body, a second high-tower body slidably disposed above the inner cavity of the first high-tower body, lifting components disposed on the surfaces of the first high-tower body and the second high-tower body, the lifting components comprising a first annular fixing plate and a second annular fixing plate, the first annular fixing plate being fixedly disposed on the outer surface of the first high-tower body, the second annular fixing plate being fixedly disposed on the outer surface of the second high-tower body, a plurality of hydraulic push rods being fixedly disposed in a ring between the first annular fixing plate and the second annular fixing plate, a discharge port being fixedly disposed at the bottom end of the first high-tower body, and a top cover being fixedly disposed at the top end of the second high-tower body.
[0007] In a preferred embodiment, an air inlet pipe is fixedly provided in an annular shape on the outer surface of the discharge port, and an air outlet pipe is fixedly provided on one side of the upper surface of the top cover.
[0008] In a preferred embodiment, a feed pipe is fixedly provided at the center of the inner cavity of the top cover, and a connecting block is fixedly provided at the bottom end of the feed pipe.
[0009] In one preferred embodiment, the outer surface of the connecting block is fixedly provided with a plurality of discharge pipes in a ring shape.
[0010] In a preferred embodiment, a perforated plate is fixedly provided in the inner cavity of the second tower body.
[0011] In a preferred embodiment, an annular groove is provided in the inner cavity of the second tower body above the perforated plate. An annular plate is slidably arranged in the inner cavity of the annular groove. Several helical blades are fixedly arranged in an annular shape on the inner sidewall of the annular plate. The ends of the helical blades away from the annular plate are fixedly connected by a connecting shaft.
[0012] In a preferred embodiment, a number of heat dissipation fins are fixedly arranged on the outer surface of the second tower body below the perforated plate.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] This invention features a lifting component. A hydraulic push rod drives the second annular fixed plate to rise and fall, which in turn causes the second tower body to slide and rise along the inner wall of the first tower body. This process adjusts the material drop height, controls the impact speed of the particles, prevents particle breakage or unevenness, and ensures that the material is formed under optimal conditions. This improves the practicality of the device and the uniformity of granulation.
[0015] This invention utilizes the coordinated arrangement of an air inlet pipe, an annular plate, and an air outlet pipe. External air enters the interior of the first and second tower bodies through the air inlet pipe and is discharged to the outside through the air outlet pipe, forming a circulating airflow. This airflow drives the annular plate to rotate along the annular groove, which in turn drives the spiral blades and connecting shaft to rotate. The airflow then performs secondary stirring and dispersion of the material, thereby promoting the uniform formation of particles.
[0016] This invention, through the coordinated arrangement of a feed pipe, a connecting block, and a discharge pipe, allows liquid materials to be added to the connecting block via the feed pipe and discharged downwards in a ring shape via the discharge pipe. This causes the liquid materials to be flushed onto the surface of the spiral blades, facilitating secondary mixing and dispersion of the materials and further improving the practicality and particle uniformity of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 This utility model provides a technical solution: a high-tower granulation device for compound fertilizer production, including a first high-tower body 1, a second high-tower body 4 slidably disposed above the inner cavity of the first high-tower body 1, and lifting components disposed on the surfaces of the first high-tower body 1 and the second high-tower body 4. The lifting components include a first annular fixing plate 5 and a second annular fixing plate 6. The first annular fixing plate 5 is fixedly disposed on the outer surface of the first high-tower body 1, and the second annular fixing plate 6 is fixedly disposed on the outer surface of the second high-tower body 4. Several hydraulic push rods 7 are fixedly arranged in a ring. The bottom end of the first tower body 1 is fixedly provided with a discharge port 2, and the top end of the second tower body 4 is fixedly provided with a top cover 14. The hydraulic push rods 7 drive the second annular fixed plate 6 to rise and fall. The second annular fixed plate 6 drives the second tower body 4 to slide and rise and fall along the inner wall of the first tower body 1. The falling height of the material is adjusted in turn. By adjusting the falling height, the impact speed of the particles is controlled, avoiding the breakage or unevenness of the particles, ensuring that the material is formed under the best conditions, and improving the practicality of the device and the uniformity of granulation.
[0025] like Figure 1-4 As shown, an air inlet pipe 3 is fixedly installed in a ring shape on the outer surface of the discharge port 2, an air outlet pipe 15 is fixedly installed on one side of the upper surface of the top cover 14, a feed pipe 16 is fixedly installed at the center of the inner cavity of the top cover 14, a connecting block 17 is fixedly installed at the bottom end of the feed pipe 16, and several discharge pipes 18 are fixedly installed in a ring shape on the outer surface of the connecting block 17. An orifice plate 9 is fixedly installed in the inner cavity of the second tower body 4. This high tower granulation equipment enhances the ventilation of the material by setting an annular air inlet pipe 3 on the outside of the discharge port 2, which helps to promote the drying and quality improvement of the granules. At the same time, the air outlet pipe 15 installed on one side of the top cover 14 further improves the airflow circulation efficiency. The design of the central feed pipe 16 allows the material to enter smoothly. The annular arrangement of the connecting block 17 and the multiple discharge pipes 18 ensure the uniform distribution and efficient discharge of the material. In addition, the orifice plate 9 of the second tower body 4 optimizes the flowability of the material and enhances the overall production efficiency.
[0026] like Figure 1-4As shown, an annular groove 10 is provided in the inner cavity of the second tower body 4 above the perforated plate 9. An annular plate 11 is slidably arranged in the inner cavity of the annular groove 10. Several spiral blades 12 are fixedly arranged in an annular shape on the inner sidewall of the annular plate 11. The ends of the spiral blades 12 away from the annular plate 11 are fixedly connected by a connecting shaft 13. Several heat dissipation fins 8 are fixedly arranged on the outer surface of the second tower body 4 below the perforated plate 9. By setting the annular groove 10 in the inner cavity of the second tower body 4 and slidingly installing the annular plate 11, together with several spiral blades 12, the mixing and lifting effect of the material is effectively optimized. The layout of the spiral blades 12 not only improves the flowability of the material, but also enhances the overall granulation efficiency. In addition, the heat dissipation fins 8 fixed below the second tower body 4 help to dissipate heat in a timely manner, improving the safety and stability of the equipment operation.
[0027] Working principle: In operation, liquid material is first added to connecting block 17 through feed pipe 16 and discharged downwards in a ring through discharge pipe 18, causing the liquid material to rush towards the surface of spiral blade 12. External air enters the interior of the first tower body 1 and the second tower body 4 through air inlet pipe 3 and is discharged to the outside through air outlet pipe 15. The air circulation and the impact airflow formed by the falling liquid material drive the annular plate 11 to rotate along the annular groove 10. The annular plate 11 drives the spiral blade 12 and connecting shaft 13 to rotate, performing secondary stirring and dispersion of the material. The stirred and dispersed liquid material will then fall through the airflow. The surface of the perforated plate 9 allows liquid material to fall continuously through holes of uniform size. With the help of the heat dissipation fins 8, the liquid material is rapidly cooled. By activating the hydraulic push rod 7, the second annular fixed plate 6 is raised and lowered. The second annular fixed plate 6, in turn, causes the second tower body 4 to slide and rise along the inner wall of the first tower body 1. This process adjusts the falling height of the material, controlling the impact speed of the particles to prevent breakage or unevenness. This ensures that the material is formed under optimal conditions, guaranteeing the uniformity of the particles. The overall operation is convenient and easy to use, making it suitable for large-scale application and promotion.
[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
