Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer production technology, and more specifically, to an organic fertilizer production drying device. Background Technology

[0002] In the field of organic fertilizer production, the demand for organic fertilizers continues to grow due to the global emphasis on ecological agriculture and sustainable development. The quality of organic fertilizers is crucial for crop growth and soil improvement. Drying is one of the key steps in the organic fertilizer production process.

[0003] Chinese Patent Announcement No. 202322275826.6 discloses a drying device for organic fertilizer production. This solution utilizes a rotating drying drum structure to continuously tumble the material, achieving all-around drying and ensuring uniform heating of the fertilizer, thus improving the drying effect. The internal fixed drum sidewall is equipped with resistance heating tubes. A gas-feeding drying structure, including a drying pipe and a filter cylinder, heats and delivers clean air, which has been adsorbed by an adsorbent to remove water vapor and dust, into the drying drum, ensuring clean hot air during the drying process and improving the drying quality of the organic fertilizer. The resistance heating tubes achieve uniform heating of the circumference of the drying drum, accelerating the drying speed. The device is equipped with a state-switching structure; the extension and retraction of a hydraulic cylinder allows for switching between the feeding / discharging and rotating drying states, making operation simple.

[0004] However, in the improved version of the above patent, the fertilizer is prone to scale buildup on the inner wall of the drying drum during the drying process. Once scale buildup occurs, it will affect the heat transfer efficiency, increase energy consumption, and also reduce the drying quality of the fertilizer. Therefore, an organic fertilizer production drying device is proposed to address the above problems. Utility Model Content

[0025] Example:

[0026] Please see Figure 1-2 An organic fertilizer production drying device includes a shell 1. Inside the shell 1, a fixing rod 2, an inner cylinder 3, and an outer cylinder 4 are fixedly installed. The fixing rod 2 passes through the inner cylinder 3 and the outer cylinder 4 and is fixedly connected to them. Inside the shell 1, a first rotating ring 7 and a second rotating ring 8 are rotatably connected. The first rotating ring 7 is inserted into the inner cylinder 3 and is rotatably connected to it. The second rotating ring 8 is inserted into the outer cylinder 4 and is rotatably connected to it. Two scrapers 13 are fixedly installed on the side of the first rotating ring 7 and the second rotating ring 8 near the inner cylinder 3. Several scrapers 13 are slidably connected to the inner cylinder 3 and the outer cylinder 4 respectively. Several filter holes 5 are opened on the inner cylinder 3.

[0027] Side plates 24 are fixedly installed on both sides of the shell 1. A controller 25 is embedded in one side of one of the side plates 24. The controller 25 is electrically connected to the servo motor 12, the electric telescopic rod 16, the solar collector 20, the gas mixing device 22 and the suction pump. A feed pipe 23 is fixedly installed on one side of the shell 1 and is inserted into and connected to the inner cylinder 3. A panel is rotatably connected to one side of the feed pipe 23 via a rotating shaft.

[0028] The scraper 13 scrapes against the inner walls of the inner cylinder 3 and outer cylinder 4, thereby reducing the possibility of scaling on the inner walls and minimizing the impact on the drying of organic fertilizer. The filter holes 5 also screen the organic fertilizer, further improving the drying quality of the organic fertilizer.

[0029] Please see Figure 3 Several scrapers 13 are fixedly installed with several stirring blades 14 on one side near the fixed rod 2, and the stirring blades 14 are slidably connected to the fixed rod 2 and the inner cylinder 3 respectively.

[0030] The housing 1 is rotatably connected to the frame 6. Two corresponding connecting blocks 9 are fixedly installed on one side of the first rotating ring 7 and the second rotating ring 8. Several connecting blocks 9 are fixedly connected to the frame 6. The housing 1 is fixedly installed with a servo motor 12. A gear 11 is fixedly installed at the output end of the servo motor 12. A gear ring 10 meshes with the outside of the gear 11. The gear ring 10 is fixedly connected to the frame 6. The connecting blocks 9, the gear ring 10 and the gear 11 are all rotatably connected to the housing 1.

[0031] Inside the housing 1, and on one side of the inner cylinder 3 and the outer cylinder 4, there are first baffles 1502 and second baffles 1501 respectively. The two first baffles 1502 and the two baffles 1501 are inserted into the inner cylinder 3 and the outer cylinder 4 respectively and are slidably connected to them. Two electric telescopic rods 16 are provided on one side of each of the two first baffles 1502 and the two baffles 1501. The output ends of several electric telescopic rods 16 are fixedly connected to the first baffles 1502 and the second baffles 1501 respectively. Several electric telescopic rods 16 are fixedly connected to the housing 1. The inner walls of the inner cylinder 3 and the outer cylinder 4 are both tapered.

[0032] The dried organic fertilizer inside the inner cylinder 3 and outer cylinder 4 is stirred by several stirring blades 14 to reduce local overheating or uneven drying. At the same time, the gear 11 drives the gear ring 10 to rotate through the servo motor 12, and the first rotating ring 7 and the second rotating ring 8 are connected by the connecting block 9 to rotate synchronously. This enables several scrapers 13 to rotate synchronously. The electric telescopic rod 16 operates to move the first baffle 1502 and the second baffle 1501 in sequence, which facilitates the sequential feeding of the dried organic fertilizer after screening inside the inner cylinder 3 and outer cylinder 4. In addition, the inner walls of the inner cylinder 3 and outer cylinder 4 are both conical, which facilitates the output of organic fertilizer.

[0033] Please see Figure 4 A heat-insulated hot water tank 19 and a solar collector 20 are provided on one side of the shell 1. A fixed pipe 21 is provided on the side of the heat-insulated hot water tank 19 away from the shell 1. The fixed pipe 21 passes through the heat-insulated hot water tank 19 and is fixedly connected to it. An air pump is provided on one side of the heat-insulated hot water tank 19 and on the fixed pipe 21. A connecting pipe 17 is fixedly installed inside the shell 1.

The air outlets 18 are inserted into the interior of the connecting pipe 17 and communicate with it. The fixed pipe 21 is inserted into the interior of the shell 1 and is fixedly connected to it. The fixed pipe 21 is inserted into the interior of the connecting pipe 17 and communicates with it. A gas mixing device 22 is provided inside the shell 1 and on the fixed pipe 21.

[0034] By installing a gas mixing device 22 on the fixed pipe 21 before the hot air enters the drying equipment, nitrogen can be mixed with the hot air in a certain proportion as needed to reduce the oxygen content of the hot air, preventing the organic fertilizer from undergoing an oxidation reaction during the drying process and affecting the quality of the fertilizer. At the same time, an insulation layer is fitted on the exposed fixed pipe 21, so that the existing insulated hot water tank 19 and solar collector 20 can work together to convert solar energy into heat energy, which is used to preheat the air entering the shell 1 through the fixed pipe 21, thereby improving the utilization rate of resources. Meanwhile, a water inlet is provided on the insulated hot water tank 19.

[0035] Working principle: By opening the panel on the feed pipe 23, organic fertilizer is transported into the inner cylinder 3 through the feed pipe 23. By closing the panel, the temperature of the organic fertilizer inside the shell 1 during drying is reduced. The servo motor 12 drives the gear 11 to rotate the gear ring 10. The connecting block 9 connects the first rotating ring 7 and the second rotating ring 8 to rotate synchronously. Several scrapers 13 and stirring blades 14 rotate synchronously to scrape the inner walls of the inner cylinder 3 and the outer cylinder 4 and to stir the dried organic fertilizer inside. The electric telescopic rod 16 operates to move the first baffle 1502 and the second baffle 1501 in sequence, which facilitates the sequential feeding of the screened and dried organic fertilizer inside the inner cylinder 3 and the outer cylinder 4.
