Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer granulation technology, and in particular to a drying device for organic-inorganic compound fertilizer granulation. Background Technology

[0002] Organic-inorganic compound fertilizers combine the long-lasting effects of organic nutrients with the rapid-acting effects of inorganic nutrients. In agricultural production, they can effectively improve soil fertility and promote crop growth. The drying process after granulation is a key step in ensuring product quality. Granulated compound fertilizer granules typically contain 10% to 12% moisture. If drying is incomplete, they are prone to pulverization and clumping during storage, making them unsuitable for mechanized fertilization and leading to nutrient loss. If drying is excessive, it will waste energy, increase costs, and increase breakage rates. Therefore, the drying equipment needs to precisely control the moisture evaporation process to keep the granule moisture content stable within the optimal range while maintaining granule integrity. It is the core equipment connecting granulation and finished product packaging in the large-scale production of compound fertilizers and is of great significance for improving fertilizer marketability and application effects.

[0003] Existing compound fertilizer granulation and drying devices are mainly hot air dryers. Their core structure includes a drying cylinder, a feed hopper, a hot air generator, and a discharge port. Mechanically, the drying cylinder is driven to rotate by a motor through chain transmission. Simple straight-plate stirring blades are welded to the inner wall of the cylinder. The hot air generator is mostly a coal-fired hot air furnace, which directly introduces hot air into the feed end of the drying cylinder through pipes.

[0004] Existing drying devices lack effective material pretreatment and dispersion structures, causing wet granules to easily agglomerate into clumps after entering the drying cylinder, affecting the uniformity of drying. Due to their high viscosity, moist compound fertilizer granules form clumps of varying sizes when directly entering the cylinder from the feed hopper. These clumps are difficult to completely break up by the straight-plate stirring blades during the cylinder's rotation, making it difficult for the particles inside the clumps to fully contact the hot air, resulting in a "dry outside, wet inside" phenomenon. Therefore, a drying device for organic-inorganic compound fertilizer granulation is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a drying device for granulation of organic-inorganic compound fertilizer, which aims to improve the problem that existing drying devices, due to the lack of an effective material pretreatment and dispersion structure, cause wet granules to easily agglomerate into clumps after entering the drying cylinder, thus affecting the uniformity of drying.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drying device for granulation of organic-inorganic compound fertilizer, comprising a feeding box, a fixing block 1 fixedly connected to the outer wall of the feeding box, a roller rotatably connected to the inner wall of the fixing block 1, symmetrical rotating wheels fixedly connected to the outer wall of the roller, an auxiliary wheel provided on the outer wall of the rotating wheel, a gear ring fixedly connected to the outer wall of the roller, a motor 1 provided below the roller, a spur gear 1 fixedly connected to the output end of the motor 1, the gear ring meshing with the spur gear 1, a lifting plate fixedly connected to the inner wall of the roller, a fixing block 2 rotatably connected to the outer wall of the roller, a discharge block fixedly connected to the inner wall of the fixing block 2, an igniter and an air outlet mechanism provided on the outer wall of the fixing block 2, and a dispersing component provided on the inner wall of the feeding box; The dispersing assembly includes a vibrating plate, a first dispersing plate, and a second dispersing plate.

[0007] Furthermore, the vibration assembly includes a vibration motor, the output end of which is fixedly connected to the inner wall of the vibration plate. Four sets of spring blocks are provided on the lower surface of the vibration plate, and a fixing plate is fixedly connected to the lower surface of the spring blocks.

[0008] Furthermore, a connecting block is fixedly connected to the outer wall of the discharge block, a connecting box is fixedly connected to the outer wall of the connecting block, and a feeding block is fixedly connected to the inner wall of the connecting block and the connecting box.

[0009] Furthermore, a collection box is fixedly connected to the outer wall of the feeding block, and a sliding box is slidably connected to the inner wall of the collection box.

[0010] Furthermore, a screening plate is provided inside the connecting block, and a sliding box II is provided below the screening plate.

[0011] Furthermore, a slide rail is slidably connected to the outer wall of the sliding box, and the outer wall of the slide rail is fixedly connected to the inner wall of the connecting box.

[0014] This utility model has the following beneficial effects: In this invention, a vibrating motor drives a vibrating plate, a first distribution plate, and a second distribution plate to vibrate, effectively breaking up agglomerated, damp compound fertilizer granules. This allows the material to enter the drum evenly in single or small clusters via a fixed block. Simultaneously, spring blocks on the fixed plate buffer the vibration, preventing the equipment from being affected by severe vibration. This dispersion method ensures that the granules form a uniform material curtain when lifted and scattered inside the drum by the lifting plates, allowing them to fully contact the dry, hot air generated by the air outlet mechanism and igniter. This reduces the possibility of incomplete or excessive drying in certain areas, significantly improves drying uniformity, shortens the overall drying time, and reduces energy consumption.

[0015] In this invention, after the dried granules fall onto the screening plate via the discharge block, the motor 2 is driven by components such as connecting rod 1, spur gear 2, and spur gear 3, and in conjunction with the meshing of half gear 1, half gear 2 and rack, drives the screening plate to slide back and forth along the slide rail. Qualified granules pass through the holes of the screening plate into sliding box 2 and are finally stored in sliding box 3, ensuring that the finished granules are of uniform size. Clumped granules are fed into sliding box 1 via feeding block 1 for subsequent processing, avoiding the mixing of unqualified products into the finished product. This not only ensures product quality but also realizes the secondary utilization of materials and reduces raw material waste. Attached Figure Description

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.

[0019] Reference Figures 1-4This utility model provides an embodiment of a drying device for granulation of organic-inorganic compound fertilizer, comprising a feeding box 1, a fixing block 2 fixedly connected to the outer wall of the feeding box 1, a roller 19 rotatably connected to the inner wall of the fixing block 2, and symmetrical rotating wheels 4 fixedly connected to the outer wall of the roller 19. The rotating wheels 4 are linked with the roller 19 and rotate synchronously under power drive, providing support for the roller 19 and transmitting rotational power, directly driving the roller 19 to achieve continuous operation. An auxiliary wheel 3 is provided on the outer wall of the rotating wheel 4, which cooperates with the rotating wheel 4 to support the roller 19, enhance the stability of the roller 19 during rotation, prevent the roller 19 from deviating or shaking during operation, and ensure the smooth operation of the drying process. A gear ring 5 is fixedly connected to the outer wall of the roller 19, and a motor 7 is provided below the roller 19. A spur gear 6 is fixedly connected to the output end of the motor 7. The gear ring 5 and the spur gear 6 mesh with each other. The spur gear 6 connects the gear ring 5 and the drum 19. It rotates under the drive of the gear ring 5, converting the rotation of the gear ring 5 into the rotation of the drum 19, realizing the transmission of power from the gear ring 5 to the drum 19. The inner wall of the drum 19 is fixedly connected to the lifting plate 26. The lifting plate 26 lifts the compound fertilizer granules and sprinkles them as the drum 19 rotates, so that the granules form a uniform material curtain, increasing the contact area with the dry hot air and improving the drying efficiency. The outer wall of the drum 19 is rotatably connected to the fixing block 2 8. The inner wall of the fixing block 2 8 is fixedly connected to the discharge block 11. The outer wall of the fixing block 2 8 is provided with an igniter 9 and an air outlet mechanism 10. The airflow of the air outlet mechanism 10 is heated by the igniter 9 to form dry hot air and enters the drum 19, providing a source of hot air for drying the compound fertilizer granules in the drum 19. The inner wall of the feed box 1 is provided with a dispersing component. The dispersing assembly includes a vibrating plate 20, a first distributing plate 24, and a second distributing plate 25. The outer wall of the vibrating plate 20 is slidably connected to the inner wall of the feed box 1. The lower surface of the first distributing plate 24 is fixedly connected to the upper surface of the vibrating plate 20. The outer wall of the second distributing plate 25 is fixedly connected to the outer wall of the vibrating plate 20. The first distributing plate 24 vibrates under the drive of the vibrating plate 20 and works in conjunction with the second distributing plate 25 to disperse the agglomerated compound fertilizer granules in the feed box 1, so that the granules are distributed in a single or small cluster state. The inner wall of the vibrating plate 20 is provided with a vibration assembly, which includes a vibration motor 23. The output end of the vibration motor 23 is fixedly connected to the inner wall of the vibrating plate 20. Four sets of spring blocks 21 are provided on the lower surface of the vibrating plate 20. A fixed plate 22 is fixedly connected to the lower surface of the spring blocks 21. The spring blocks 21 play a buffering role on the vibration of the vibrating plate 20, reducing the impact of severe vibration on other parts of the equipment and ensuring the overall stability of the equipment. The outer wall of the fixed plate 22 is fixedly connected to the inner wall of the feed box 1.

[0020] Specifically, the fixing block 2 on the outer wall of the feed box 1 provides rotational support for the roller 19. The rotating wheels 4 symmetrically arranged on the outer wall of the roller 19 rotate under power drive, and together with the auxiliary wheel 3, effectively suppress the offset and shaking of the roller 19 during operation, ensuring its stable rotation. The motor 7 serves as the power source, and through the spur gear 6 connected to the output end, it meshes with the gear ring 5 on the outer wall of the roller 19, transmitting power to the roller 19 to make it rotate. The lifting plate 26 fixed inside the drum rotates with the roller, continuously lifting the particles and scattering them to form a uniform material curtain. The fixing block 8 on the outer wall of the roller 19 not only fixes the discharge block 11, but also installs an igniter 9 and... The air outlet mechanism 10 outputs air that is heated into dry hot air by the igniter 9 and precisely delivered into the drum 19 to fully contact the material curtain, achieving efficient drying. The dispersing components in the feed box 1 work together, and the vibration motor 23 drives the vibration plate 20 to vibrate, which in turn drives the first distribution plate 24 and the second distribution plate 25 to vibrate synchronously, effectively breaking up agglomerated materials. The four sets of spring blocks 21 fixed by the fixing plate 22 below the vibration plate 20 buffer the vibration and prevent the equipment from being damaged by violent vibration. This part, through the cooperation of the dispersing components and the drying structure, achieves uniform feeding and rapid drying of materials, improving drying efficiency and uniformity.

A connecting box 13 is fixedly connected to the outer wall of the connecting block 12. A feeding block 15 is fixedly connected to the inner wall of the connecting block 12 and the connecting box 13. A collecting box 16 is fixedly connected to the outer wall of the feeding block 15. The feeding block 15 guides the clumped particles after screening to slide, allowing the clumped particles to smoothly enter the collecting box 16, providing guidance for the conveying of the clumped particles. A sliding box 17 is slidably connected to the inner wall of the collecting box 16. The sliding box 17 receives the clumped particles falling from the collecting box 16, temporarily storing the clumped particles and providing storage space for subsequent processing. A screening plate 27 is installed inside the connecting block 12. Below the screening plate 27 is a sliding box 28. A slide rail 35 is slidably connected to the outer wall of the sliding box 28. Driven by the sliding box 28, the screening plate 27 reciprocates along the slide rail 35, using its holes to screen the dried particles and separate qualified particles from agglomerated particles. The outer wall of the slide rail 35 is fixedly connected to the inner wall of the connecting box 13. A motor 24 is fixedly connected to the inner wall of the connecting box 13. A connecting rod 31 is fixedly connected to the output end of the motor 24. A spur gear 29 and a half gear 30 are fixedly connected to the outer wall of the connecting rod 31. The sliding box 2... Below the 8th slide box, a connecting rod 23 is provided. A spur gear 32 and a half gear 24 are fixedly connected to the outer wall of the connecting rod 23. The spur gear 29 meshes with the spur gear 32. The spur gear 29 cooperates with the connecting rod 1 (31) and the spur gear 32, rotating under the drive of the connecting rod 1 (31) and transmitting power to the spur gear 32. Half gear 1 (30) meshes with the half gear 2 (34). A rack 38 is fixedly connected to the lower surface of the sliding box 28. The rack 38, half gear 1 (30), and half gear 2 (34) mesh with each other. The rack 38 alternately meshes with half gear 1 (30) and half gear 2 (34). Driven by gears, the device reciprocates, which in turn causes the sliding box 28 and the screening plate 27 to slide back and forth along the slide rail 35. The outer wall of the sliding box 28 is fixedly connected to the feeding block 26, which is slidably connected to the inner wall of the collection box 28. The feeding block 26 guides the qualified particles in the sliding box 28 to slide smoothly into the collection box 28, providing guidance for the conveying of qualified particles. The inner wall of the collection box 28 is slidably connected to the sliding box 37, which receives the qualified particles falling from the collection box 28 and stores them. It is the final storage component for qualified finished particles.

[0022] Specifically, the dried granules are discharged through the discharge block 11 in the fixed block 2 8, and enter the screening area of ​​the connecting box 13 through the connecting block 12. The connecting block 12 and the feeding block 15 in the connecting box 13 are responsible for guiding the agglomerated granules, allowing them to slide smoothly into the collection box 16, and finally fall into the sliding box 17 for temporary storage for subsequent processing. The screening plate 27 inside the connecting block 12 is the core of the screening. The sliding box 28 below it slides back and forth along the slide rail 35, driving the screening plate 27 to move synchronously to achieve screening. This movement is driven by the motor 2 14, which drives the positive motor through the connecting rod 1 31. Gear 29 rotates with half gear 1 30, and spur gear 29 meshes with spur gear 32 on connecting rod 2 33, causing half gear 2 34 to rotate with connecting rod 2 33. Half gear 1 30 and half gear 2 34 alternately mesh with rack 38 below sliding box 2 28, forming a reciprocating driving force. Qualified particles fall into sliding box 2 28 through the holes of screening plate 27, slide into collection box 2 18 via feeding block 2 36, and are finally stored in sliding box 3 37. This part achieves accurate screening and classification collection of particles through the linked screening and conveying structure, ensuring the quality of finished products and reducing material waste.

[0023] Working principle: When it is necessary to dry the damp compound fertilizer granules, the compound fertilizer granules are poured into the feed box 1. The vibration motor 23 is started to generate vibration, which drives the vibration plate 20 and the first and second distribution plates 24 and 25 to vibrate synchronously, breaking up the agglomerated material and making the granules evenly distributed in single or small cluster state. They enter the drum 19 through the first fixing block 2. The spring block 21 on the fixing plate 22 can buffer the vibration of the vibration plate 20 and avoid violent vibration affecting the stability of the equipment. During the drying stage, motor 7 drives gear ring 5 to rotate, gear ring 5 drives spur gear 6 to rotate, which in turn causes drum 19 to start rotating. The symmetrical rotating wheels 4 on both sides of the drum rotate synchronously. The auxiliary wheel 3 cooperates with the rotating wheels 4 to ensure the stable operation of drum 19. The lifting plates 26 inside drum 19 lift the granules and sprinkle them down as the drum rotates, forming a uniform material curtain. The airflow output by the air outlet mechanism 10 is heated by igniter 9 to form dry hot air, which enters drum 19 and fully contacts the material curtain to achieve the drying of compound fertilizer granules. The dried compound fertilizer granules fall from the discharge block 11 inside the fixed block 28 onto the screening plate 27 inside the connecting block 12. The motor 214 drives the connecting rod 31 to rotate, which in turn drives the spur gear 29 to drive the spur gear 32 to rotate. At the same time, the half gear 30 on the connecting rod 31 and the half gear 34 outside the connecting rod 23 alternately mesh, driving the rack 38 below the sliding box 28. This causes the sliding box 28 to drive the screening plate 27 to slide back and forth along the slide rail 35, thus completing the granule screening. Qualified particles fall through the holes on the screening plate 27 into the sliding box 28, slide through the feeding block 26 into the collection box 28, and finally enter the sliding box 37 for storage. Agglomerated particles slide through the feeding block 15 into the collection box 16 and fall into the sliding box 17 for further processing.
