Description

Technical Field

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

[0002] Compound fertilizer is a chemical fertilizer containing any two or three of the crop nutrients nitrogen, phosphorus, and potassium, produced by chemical or mixing methods. Its function is to meet the comprehensive and balanced needs of agriculture under different production conditions, and it is widely used in modern agriculture. During the production of compound fertilizer, since the raw materials are processed into powder, they need to be granulated into pellets by a granulator for easy storage and transfer. Currently, granulators are generally divided into cylindrical and disc types. Chinese utility model patent, authorized announcement number "CN220194786U", discloses a compound fertilizer granulator, including a support base and a granulation turntable. A drive component is installed on one side of the support base, and the output end of the drive component is connected to one side of the granulation turntable. Support components are provided on both sides of the support base. A discharge port is opened at the edge of the granulation turntable, and a discharge component is provided on the inner wall of the discharge port. The support component includes a baffle to assist the granulation turntable in granulation. Limiting components are provided on both sides of the discharge component to limit and fix the discharge component.

[0003] The above-mentioned technical solution, through the setting of the discharge port and the first discharge plate, in conjunction with the second discharge plate, allows the discharge port of the granulation turntable to be adjusted to the lowest position before the first discharge plate is opened when discharge is required. This allows the granulated compound fertilizer to quickly roll out of the discharge port into the container, thereby effectively improving the discharge efficiency. However, the above-mentioned technical solution still has certain drawbacks. The angle of the granulation turntable of the granulator is fixed, and the angle of the turntable is not easy to adjust. The angle of the granulation turntable determines the rolling speed and movement trajectory of the material on the granulation turntable. The inconvenience of angle adjustment may lead to unstable granulation rate. When it is necessary to change the product particle size, the inconvenience of angle adjustment limits the operational flexibility, affecting production efficiency and product quality. Therefore, this utility model proposes a new solution. Utility Model Content

A movable seat 12 is slidably connected to the surface of fixed seat 11. A movable seat connecting plate 14 is fixedly connected to the lower end of movable seat 12. Movable seat connecting plate 14 is fixedly connected to rotating shaft 9. A sliding groove 13 is opened on the surface of fixed seat 11. Movable seat connecting plate 14 is slidably connected to the inner wall of sliding groove 13. A fixed plate 15 is fixedly connected to movable seat 12. A second drive motor 16 is fixedly connected to the lower end of fixed plate 15. A granulation turntable 17 is rotatably connected to fixed plate 15. The output end of the second drive motor 16 is fixedly connected to granulation turntable 17.

[0030] The compound fertilizer granulation turntable adjustment device also includes two connecting frames 18, which are symmetrically fixedly connected to the surface of the movable seat 12. A granulation turntable cover 19 is provided above the fixed plate 15. The granulation turntable cover 19 is fixedly connected to the two connecting frames 18. A compound fertilizer granule discharge channel 20 is fixedly connected to the front end of the granulation turntable cover 19. The granulation turntable 17 is rotatably connected to the granulation turntable cover 19.

[0031] Two connecting frames 18 are fixedly connected to opposite faces of a connecting plate 21. An electric telescopic rod 22 is fixedly connected inside the connecting plate 21. A scraper fixing seat 24 is fixedly connected to the output end of the electric telescopic rod 22. Two sliding rods 23 are fixedly connected to the scraper fixing seat 24. Both sliding rods 23 are slidably connected to the connecting plate 21. Multiple compound fertilizer scrapers 25 are fixedly connected to the lower end of the scraper fixing seat 24.

[0032] A compound fertilizer granule filter box 2 is fixedly connected to the base 1. A compound fertilizer granule filter plate 3 is fixedly connected inside the compound fertilizer granule filter box 2. The compound fertilizer granule filter plate 3 is inclined inside the compound fertilizer granule filter box 2. The bottom of the compound fertilizer granule filter box 2 is inclined. A first compound fertilizer granule discharge port 4 and a second compound fertilizer granule discharge port 5 are fixedly connected to the front side of the compound fertilizer granule filter box 2.

[0033] When using this device, firstly, compound fertilizer granules are added to the granulation turntable 17. Then, the second drive motor 16 is started to drive the granulation turntable 17 to rotate. Some water is sprayed on the surface of the compound fertilizer on the granulation turntable 17, so that a very thin water film is formed on the surface of the powder granules. Due to the surface tension of water, water and powder combine to form very small spherical nuclei. As the granulation turntable 17 rotates, the spherical nuclei adsorb material and gradually become granules while rolling. Under the action of centrifugal force, the granules roll towards the edge of the granulation turntable 17. During this process, the granules continuously stick to powder and become spherical. The compound fertilizer granules are blocked by the granulation turntable cover 19, so that the spherical granules can be discharged from the granulation turntable 17 through the compound fertilizer granule discharge channel 20 under the action of centrifugal force. The spherical compound fertilizer granules are continuously discharged from the granulation turntable 17, and new compound fertilizer is continuously replenished into the granulation turntable cover 19, thereby realizing the granulation cycle.

[0034] In the process of compound fertilizer production, compound fertilizers of different particle sizes are sometimes required. Starting the first drive motor 7 drives the worm gear 8 to rotate, which in turn drives the worm wheel 10 and the rotating shaft 9 to rotate. The rotating shaft 9 drives the movable seat connecting plate 14 and the movable seat 12 to rotate, which in turn drives the fixed plate 15 to rotate. The fixed plate 15 then drives the second drive motor 16 and the granulation turntable 17 to rotate, facilitating the adjustment of the angle of the granulation turntable 17. The angle of the granulation turntable 17 is one of the important factors affecting granulation. Adjusting the angle can change the force and trajectory of the material on the turntable, thus affecting the formation and size of the particles. By adjusting the tilt angle of the granulation turntable 17, the particle size can be precisely controlled to meet different production needs, improving the practicality of the device and increasing production efficiency and quality.

[0035] The granulated compound fertilizer granules are discharged into the compound fertilizer granule filter box 2 through the compound fertilizer granule discharge channel 20, and the compound fertilizer granules are filtered by the compound fertilizer granule filter plate 3. The filtration process can effectively remove dust, fine particles and other impurities from the compound fertilizer granules, improve the purity and quality of the product. Through filtration, the surface of the compound fertilizer granules is smoother and more uniform, which improves the overall appearance and market competitiveness of the product.

[0036] Finally, the filtered compound fertilizer granules are discharged from the first compound fertilizer granule discharge port 4 and the second compound fertilizer granule discharge port 5, respectively. The inclined design of the bottom of the compound fertilizer granule filter box 2 facilitates the discharge of compound fertilizer powder from the second compound fertilizer granule discharge port 5.

[0037] After the compound fertilizer granulation is completed, some compound fertilizer powder may remain on the surface of the granulation turntable 17. At this time, the electric telescopic rod 22 is activated to move the scraper fixing seat 24 and the compound fertilizer scraper 25. The scraper fixing seat 24 drives the sliding rod 23 to move inside the connecting plate 21, so that the compound fertilizer scraper 25 contacts the surface of the granulation turntable 17. The second drive motor 16 is activated to drive the granulation turntable 17 to rotate, so that the compound fertilizer scraper 25 can scrape off the residual compound fertilizer powder on the surface of the granulation turntable 17. The compound fertilizer powder flows from the gap between the compound fertilizer scrapers 25, so that the remaining compound fertilizer powder can be discharged from the compound fertilizer granule discharge channel 20. Timely scraping of powder can prevent it from mixing into the finished granules, affecting the purity and quality of the product. At the same time, it can prevent it from mixing with new compound fertilizer powder in the next compound fertilizer granulation process, causing the quality of the compound fertilizer to decline. This helps to improve production efficiency and product quality.

[0038] Furthermore, by adjusting the tilt angle of the granulation turntable 17, a suitable tilt angle helps the compound fertilizer granules to be evenly distributed on the granulation turntable 17, reducing material accumulation and wall sticking, improving granulation efficiency and pelleting rate. Different compound fertilizers have different viscosity, moisture and other characteristics. Adjusting the tilt angle of the granulation turntable 17 can better adapt to these characteristics, ensure the smooth progress of the granulation process, and accurately control the particle size to meet different production needs, thereby improving the practicality of the device and increasing production efficiency and quality.

[0039] The compound fertilizer powder on the surface of the granulation turntable 17 is scraped off by the compound fertilizer scraper 25. Timely scraping off of the powder can prevent it from being mixed into the finished granules, affecting the purity and quality of the product. At the same time, it can prevent it from mixing with new compound fertilizer powder in the next compound fertilizer granulation process, which would cause the quality of the compound fertilizer to decline. This helps to improve production efficiency and product quality.

[0040] Working principle: When using this device, firstly, compound fertilizer granules are added to the granulation turntable 17. Then, the second drive motor 16 is started to drive the granulation turntable 17 to rotate. Some water is sprayed on the surface of the compound fertilizer on the granulation turntable 17, so that a very thin water film is formed on the surface of the powder granules.

The compound fertilizer granules are blocked by the granulation turntable cover 19, so that the spherical granules can be discharged from the granulation turntable 17 through the compound fertilizer granule discharge channel 20 under the action of centrifugal force. The spherical compound fertilizer granules are continuously discharged from the granulation turntable 17, and new compound fertilizer is continuously replenished into the granulation turntable cover 19, thereby realizing the granulation cycle.

[0041] In the process of compound fertilizer production, compound fertilizers of different particle sizes are sometimes required. Starting the first drive motor 7 drives the worm gear 8 to rotate, which in turn drives the worm wheel 10 and the rotating shaft 9 to rotate. The rotating shaft 9 drives the movable seat connecting plate 14 and the movable seat 12 to rotate, which in turn drives the fixed plate 15 to rotate. The fixed plate 15 then drives the second drive motor 16 and the granulation turntable 17 to rotate, facilitating the adjustment of the angle of the granulation turntable 17. The angle of the granulation turntable 17 is one of the important factors affecting granulation.

By adjusting the tilt angle of the granulation turntable 17, the particle size can be precisely controlled to meet different production needs, improving the practicality of the device and increasing production efficiency and quality.

[0042] The granulated compound fertilizer granules are discharged into the compound fertilizer granule filter box 2 through the compound fertilizer granule discharge channel 20, and the compound fertilizer granules are filtered by the compound fertilizer granule filter plate 3. The filtration process can effectively remove dust, fine particles and other impurities from the compound fertilizer granules, improve the purity and quality of the product. Through filtration, the surface of the compound fertilizer granules is smoother and more uniform, which improves the overall appearance and market competitiveness of the product.

[0043] Finally, the filtered compound fertilizer granules are discharged from the first compound fertilizer granule discharge port 4 and the second compound fertilizer granule discharge port 5, respectively. The inclined design of the bottom of the compound fertilizer granule filter box 2 facilitates the discharge of compound fertilizer powder from the second compound fertilizer granule discharge port 5.

[0044] After the compound fertilizer granulation is completed, some compound fertilizer powder may remain on the surface of the granulation turntable 17. At this time, the electric telescopic rod 22 is activated to move the scraper fixing seat 24 and the compound fertilizer scraper 25.
