Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a drying device for organic fertilizer production. Background Technology
[0002] In the production of organic fertilizer, the drying process is crucial. After fermentation and other treatments, wet organic fertilizer raw materials typically contain high moisture content. High moisture content not only makes storage and transportation difficult but also affects the subsequent application effectiveness. Therefore, using drying equipment to efficiently dry wet materials and remove excess moisture is an important process in organic fertilizer production. Through high-temperature drying, the moisture in the material is evaporated, ultimately forming a dry organic fertilizer product, ensuring better results during use.
[0003] In existing technologies, most organic fertilizer drying equipment focuses primarily on drying efficiency, neglecting waste gas treatment and the equipment's self-cleaning function. Traditional equipment often lacks effective anti-sticking structures, causing materials to easily adhere to the inner walls of the equipment during drying, affecting drying efficiency and stable operation. Simultaneously, waste gas treatment technologies are relatively simple, failing to effectively filter harmful gases and odors. Direct emission of waste gas can negatively impact the health of workers. These shortcomings limit the safety and efficiency of the equipment.
[0004] Therefore, a drying device for organic fertilizer production is proposed to solve the above problems. Utility Model Content

[0034] The stirring mechanism includes a motor 2, which is fixedly connected to the top of the main body 3 of the drying device. A rotating shaft 9 is fixedly connected to the output end of the motor 2. Multiple stirring rods 10 are fixedly connected to the outside of the rotating shaft 9. An anti-sticking component is provided at the end of the stirring rod 10 away from the rotating shaft 9.
[0035] The insulation shell 5 is used to effectively maintain the internal temperature of the drying device body 3, improve drying efficiency, and reduce heat loss. The drying device body 3, as the core drying structure, is used to contain the organic fertilizer raw materials to be processed and to perform the drying operation. The feed inlet 4 is used to evenly feed the wet organic fertilizer into the drying device body 3, ensuring smooth material entry. The discharge pipe 6 is located at the bottom of the drying device body 3 and extends through the bottom of the insulation shell 5, used to discharge the dried organic fertilizer from the device for easy collection and transportation for subsequent processing. The stirring mechanism is located inside the drying device body 3 to prevent the mixing of materials during the drying process. The mixing mechanism continuously agitates and disperses materials to prevent clumping and improve drying uniformity. The motor 2 serves as the power source for the mixing mechanism, driving the rotating shaft 9 to rotate. The rotating shaft 9 is connected to multiple mixing rods 10. During rotation, the mixing rods 10 achieve multi-angle mixing of the materials. At the same time, the end of the mixing rod 10 away from the rotating shaft 9 is equipped with an anti-sticking component, which can effectively reduce the adhesion of wet materials to the inner wall of the drying device body 3 during the mixing process, thereby improving the equipment's self-cleaning ability. In addition, the purification mechanism set on the outside of the insulation shell 5 is used to treat the exhaust gas and odor generated during the drying process, ensuring that emissions meet standards and improving the working environment.
[0036] Reference Figure 1 , Figure 4 and Figure 5The purification mechanism includes a purification box 7, which is fixedly connected to the outside of the insulation shell 5 by a bracket. An air inlet pipe 1 is fixedly connected to the outside of the purification box 7. The end of the air inlet pipe 1 away from the purification box 7 is fixedly connected to the inside of the drying device body 3. An activated carbon plate 15 is slidably connected inside the purification box 7. A fixing block 20 is fixedly connected to the outside of the activated carbon plate 15. A locking component is provided on the outside of the purification box 7. An air outlet pipe 8 is fixedly connected to the top of the purification box 7. A pull ring 16 is rotatably connected to the outside of the activated carbon plate 15.
[0037] The purification box 7 is used to purify the exhaust gas generated during the drying process, ensuring that the emitted gas meets the standards and reducing the spread of odors. The purification box 7 is stably installed on the outside of the insulation shell 5 by a bracket to ensure structural stability. An air inlet pipe 1 is fixedly connected to the outside of the purification box 7 to guide the exhaust gas generated inside the main body 3 of the drying device into the purification box 7. The end of the air inlet pipe 1 away from the purification box 7 is inserted into the inside of the main body 3 of the drying device to achieve effective drainage of exhaust gas. An activated carbon plate 15 is slidably connected inside the purification box 7. The activated carbon plate 15 has excellent adsorption performance and is used to adsorb harmful gases and odor particles in the exhaust gas to achieve the purification purpose. A fixing block 20 is fixedly connected to the outside of the activated carbon plate 15, which is used to lock the fixing block 20 with the locking component, thereby locking the activated carbon plate 15. A locking component is provided on the outside of the purification box 7 to position and fix the activated carbon plate 15 in the use position to ensure stable purification effect. An exhaust pipe 8 is fixedly connected to the top of the purification box 7 to discharge the purified gas outside the device, avoid pressure accumulation, and improve exhaust efficiency. A pull ring 16 is also rotatably connected to the outside of the activated carbon plate 15, which makes it easy for operators to pull it out of the purification box 7 when replacing or maintaining it, improving the convenience of operation and equipment maintenance efficiency.
[0038] Reference Figure 1 - Figure 3 The anti-stick component includes a housing 13. The outer side of the housing 13 is fixedly connected to the end of the stirring rod 10 away from the rotating shaft 9. Multiple springs 14 are provided inside the housing 13. A limiting plate 12 is slidably connected inside the housing 13. A scraper 11 is fixedly connected to one side of the limiting plate 12. The scraper 11 passes through one side of the housing 13 and is slidably connected inside the housing 13. The side of the scraper 11 away from the limiting plate 12 abuts against the inner wall of the drying device body 3. One end of the spring 14 is fixedly connected to the side of the limiting plate 12 away from the scraper 11, and the other end of the spring 14 abuts against the inner wall of the housing 13.
[0039] The anti-sticking component is used to prevent materials from adhering to the inner wall of the drying device body 3 during the drying process, thereby affecting the stirring efficiency and equipment operation stability. The outer shell 13 is fixedly connected to the end of the stirring rod 10 away from the rotating shaft 9. As the main load-bearing structure of the anti-sticking component, it is used to accommodate the internal functional parts and rotate together with the stirring rod 10. Multiple springs 14 are installed inside the outer shell 13. The springs 14 are used to provide elastic thrust to realize the automatic wall-adhesion function of the scraper 11 and improve the de-sticking effect. A limiting plate 12 is slidably connected inside the outer shell 13. The limiting plate 12 serves as a support for the scraper 11, used to drive the scraper 11 to slide and prevent the scraper 11 from slipping. Outside the outer casing 13, a scraper 11 is fixedly connected to one side of the limiting plate 12. The scraper 11 passes through one side of the outer casing 13 and is slidably connected inside the outer casing 13. The end of the scraper 11 away from the limiting plate 12 abuts against the inner wall of the drying device body 3. With the help of rotation and elasticity, the scraper 11 continuously scrapes off the residue on the inner wall, effectively reducing adhesion and material accumulation. One end of the spring 14 is fixedly connected to the side of the limiting plate 12 away from the scraper 11, and the other end abuts against the inner wall of the outer casing 13, forming an elastic torque that keeps the scraper 11 in contact with the inner wall of the drying device body 3. This ensures that the inner wall of the equipment is cleaned in real time during the drying and stirring process, enhancing the operational stability and self-cleaning ability of the device.
[0040] Reference Figure 1 , Figure 4 and Figure 5 The locking assembly includes a protective shell 19, which is fixedly connected to the outside of the purification box 7. A pin 18 is slidably connected inside the protective shell 19. A pad 21 is fixedly connected to the outside of the pin 18. A spring 17 is sleeved on the outside of the pin 18. The pin 18 is inserted into the inside of the fixing block 20. The pad 21 is slidably connected inside the protective shell 19. One end of the spring 17 is fixedly connected to the top of the pad 21, and the other end of the spring 17 abuts against the inner wall of the protective shell 19.
[0041] The locking assembly is used to effectively fix the activated carbon plate 15 inside the purification chamber 7, preventing it from shaking or shifting during equipment operation and ensuring the stability of the purification effect. The protective shell 19 is fixedly connected to the outside of the purification chamber 7, serving as the external support shell of the locking structure to accommodate and protect the internal locking elements. A pin 18 is slidably connected inside the protective shell 19, which is used to insert into the fixing block 20 to position and fix the activated carbon plate 15, preventing it from accidentally coming out during sliding. A pad 21 is fixedly connected to the outside of the pin 18, allowing the pin 18 to slide stably inside the protective shell 19 and holding the spring 17. The elastic force is transmitted to the pin 18. A second spring 17 is sleeved on the outside of the pin 18. The second spring 17 provides the reset elastic force of the pin 18, ensuring that the pin 18 always remains locked when no external force is applied. The pin 18 is inserted into the fixed block 20, so that the fixed block 20 and the pin 18 cooperate to complete the stable fixation of the activated carbon plate 15. The pad 21 is slidably connected inside the protective shell 19 to ensure smooth and controlled insertion and removal. One end of the second spring 17 is fixedly connected to the top of the pad 21, and the other end abuts against the inner wall of the protective shell 19 to form an elastic reset structure, so that the pin 18 automatically returns to the locked state after the external force is released, enhancing the convenience and safety of operation.
[0042] Working Principle: When the equipment starts running, wet organic fertilizer raw materials are fed into the main body 3 of the drying device through the feed inlet 4. After the motor 2 starts, it drives the rotating shaft 9 to rotate, thereby driving the multiple stirring rods 10 connected to it to rotate synchronously. During the rotation of the stirring rods 10, the anti-sticking components set at their ends rotate accordingly. The scraper 11, under the elastic force of the spring 14, always sticks to the inner wall surface of the main body 3 of the drying device and continuously scrapes it during rotation, avoiding the accumulation or adhesion of materials on the inner wall, ensuring uniform mixing and thorough drying, and improving drying efficiency. After the material is dried and mixed by hot air inside the main body 3 of the drying device, the moisture gradually evaporates and is finally discharged through the discharge pipe 6 set at the bottom. The exhaust gas generated during the drying process is introduced into the purification box 7 set on the outside of the insulation shell 5 through the air inlet pipe 1. When the exhaust gas passes through the activated carbon plate 15, the internal adsorption layer adsorbs and purifies the harmful gases and odor particles in it. The purified gas is discharged through the air outlet pipe 8 at the top of the purification box 7. The entire purification process is completed by the cooperation between the activated carbon plate 15 and the air inlet flow path. When the activated carbon plate 15 needs to be replaced after prolonged use, pull the pin 18 out of the fixing block 20, and then pull the activated carbon plate 15 out of the purification box 7 through the pull ring 16 on the outside of the activated carbon plate 15. Then, insert the new activated carbon plate 15 back into the purification box 7, and release the pin 18. Under the action of the spring 17, the pin 18 will re-insert into the fixing block 20, thus completing the replacement of the activated carbon plate 15. The entire device, with the coordinated cooperation of its components, achieves continuous drying of organic fertilizer raw materials and simultaneous purification and discharge of waste gas.
