[0002] Compound fertilizer refers to chemical fertilizer containing two or more nutrients. Compound fertilizer has the advantages of high nutrient content, few by-products and good physical properties. Fertilizer granulation is an indispensable step in fertilizer production. For example, a granulation device for producing high-tower nitrate-sulfur-based compound fertilizer is disclosed in application number 202421595113.6. This patent solves the problem that the molten fertilizer is easy to cool and condense on the inner wall of the high tower when the granulation device is working, and the tail gas of secondary cooling after fertilizer granulation requires additional treatment equipment, which is costly. However, during the conveying and batching process, it is inconvenient to separate and store different ingredients, and jamming is prone to occur during the conveying process, affecting the feeding effect.

[0013] According to the above technical solution, a high-efficiency and energy-saving low-carbon production process for compound fertilizer includes the following steps: S1. The proportioned straw and ingredients are separately fed into the crushing channel for storage. Then, the drive motor is started to make the crushing roller rotate and crush the straw and ingredients to form uniform fragments. S2. At the same time, the rotation of the crushing roller drives the traction disc to rotate, and through the cooperation of the swing arm and the lifting frame, the shaking plate is driven to swing back and forth to continuously shake the material being fed. S3. The crushed debris is conveyed through the conveying cylinder and mixed during the conveying process to form a uniform mixture. Then, it is evenly conveyed between the three extrusion rollers through the feeding pipe and the distribution cylinder. S4. Start the rotary granulation motor to drive the rotary disc, rotary shaft, rotary support and material scraper to rotate, and gather the mixture onto the inner wall of the ring die cylinder; S5. At the same time, the rotating bracket drives the extrusion roller to revolve, so that the extrusion roller generates its own rotation through friction with the material, and squeezes the material accumulated on the inner wall of the ring die cylinder through the mesh of the ring die cylinder to form strip fertilizer. S6. Additionally, the rotating material tray drives the positioning knife holder and the inclined scraper to rotate along the outside of the ring die cylinder, cutting the extruded strip fertilizer into granules, and throwing the granules into the discharge channel, where they fall onto the shaking screen. S7. The rotary granulation motor drives the cam to rotate through the transmission wheel and internal gear belt, which in turn drives the swing frame, the shaking top rod and the shaking screen to swing back and forth, screening the fertilizer granules so that qualified granules enter the receiving box and crushed granules are discharged through the waste discharge chute for collection, which is convenient for re-crushing and granulation.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. A crushing anti-blocking and conveying mixing mechanism is set up. Through the cooperation of the crushing channel, the material distribution plate and the feeding hopper, the straw and the ingredients are stored separately and fed in an orderly manner, avoiding the phenomenon of mutual interference between raw materials with different physical properties during crushing. At the same time, the drive motor drives two sets of crushing rollers to rotate synchronously relative to each other, so as to efficiently crush different materials at the same time, making them into uniform fragments, which facilitates subsequent granulation. Meanwhile, through the linkage of the traction disc, swing arm and lifting frame, the crushing roller, while rotating and crushing, drives the drive rod and the shaking plate to swing back and forth, continuously shaking the material during the feeding process. This prevents loose straw from bridging or getting stuck at the feed inlet, ensuring the continuity and smoothness of the feeding. Then, through the conveying auger, the straw fragments and ingredient powder are evenly mixed, providing a uniform mixture for subsequent granulation and avoiding nutrient deviation in the granules caused by uneven mixing.

[0015] 2. A high-efficiency granulation and screening mechanism is set up. Through the cooperation of a rotary granulation motor, a rotary material tray and a rotary support, the extrusion rollers revolve inside the ring die cylinder. The friction of the mixture drives the extrusion rollers to rotate, continuously extruding and forming the material accumulated on the inner wall of the ring die cylinder for granulation. In addition, during rotation, the material scraper pushes the mixture on the inner wall of the ring die cylinder, which facilitates the subsequent extrusion of the extrusion rollers and improves the efficiency of extrusion granulation. By using an inclined scraper to rotate with the rotating material tray, the strip-shaped fertilizer extruded from the ring die cylinder mesh is cut into granules, and centrifugal force is used to throw them out, realizing the integrated continuous operation of granulation, cutting and discharge. The thrown fertilizer granules enter the vibrating screen inside the discharge channel. Through the cooperation of the rotary granulation motor, transmission wheel and internal toothed belt, the cam is driven to rotate, which in turn drives the swing frame to move back and forth. With the cooperation of the tension spring, the vibrating top rod and the vibrating screen swing back and forth to screen. The qualified granules are sent into the receiving box, while the broken granules are discharged from the waste discharge trough for classification and collection, so that they can be returned to the feeding hopper for granulation later, reducing material waste and improving the yield. In addition, by moving the adjusting slider driven by the fine-tuning screw, the gap between the extrusion roller and the ring die cylinder can be adjusted from the outside, ensuring that a stable extrusion effect can still be maintained when the die wears or the material properties change, thus extending the service life and adaptability of the equipment.

[0016] In summary, the combination of a crushing and anti-clogging mixing mechanism and a high-efficiency granulation and screening mechanism facilitates the processing of straw into compound fertilizer, increasing resource utilization. During processing, straw is prevented from clogging the equipment, ensuring effective crushing. Subsequent conveying ensures uniform mixing of straw fragments and other ingredients, guaranteeing the uniformity of component content in each granule. Furthermore, rapid screening after granulation separates intact granules from broken ones, ensuring a high yield. Broken granules can be recycled and reused for granulation, reducing resource waste and achieving production goals efficiently, energy-saving, and environmentally friendly.

[0026] like Figure 8 As shown, a high-efficiency and energy-saving low-carbon production process for compound fertilizer includes the following steps: S1. The proportioned straw and ingredients are separately fed into the crushing channel 301 for storage. Then, the drive motor 312 is started to make the crushing roller 310 rotate to crush the straw and ingredients and form uniform fragments. S2. At the same time, the crushing roller 310 rotates, driving the traction disc 313 to rotate. Then, through the cooperation of the swing arm 309 and the lifting frame 307, the shaking plate 305 is driven to swing back and forth, continuously shaking the material being fed. S3. The crushed debris is conveyed through the conveying cylinder 314 and mixed during the conveying process to form a uniform mixture. Then, it is evenly conveyed between the three extrusion rollers 408 through the feeding pipe 320 and the distributing cylinder 319. S4. Start the rotary granulation motor 403 to drive the rotary material tray 404, rotary shaft 405, rotary support 406 and material scraper 409 to rotate, and gather the mixture onto the inner wall of the ring die cylinder 410. S5. At the same time, the rotating bracket 406 drives the extrusion roller 408 to revolve, so that the extrusion roller 408 generates its own rotation through friction with the material, and squeezes the material accumulated on the inner wall of the ring die cylinder 410 through the mesh of the ring die cylinder 410 to form strip fertilizer. S6. Additionally, the rotating material tray 404 drives the positioning knife holder 411 and the inclined scraper 412 to rotate along the outside of the ring die cylinder 410, cutting the extruded strip fertilizer into granules, and throwing the granules into the discharge channel 416, where they fall onto the shaking screen 418. S7. The rotary granulation motor 403 drives the cam 421 to rotate through the transmission wheel 422 and the internal toothed belt 423, which pushes the swing frame 419, the shaking top rod 417 and the shaking screen 418 to swing back and forth, screen the fertilizer granules, so that qualified granules enter the receiving box 424, and the crushed granules are discharged through the waste discharge trough for collection, which is convenient for re-crushing and granulation.

[0027] The working principle and usage process of this invention are as follows: First, the proportioned straw and ingredients are put into the crushing channel 301 respectively, and the straw and ingredients are stored separately through the cooperation of the material distribution plate 303. Then, the drive motor 312 is started to rotate the crushing roller 310. At the same time, through the transmission gear 311, the two crushing rollers 310 rotate synchronously relative to each other to crush the straw and ingredients, so as to form fragments, which facilitates subsequent granulation. At the same time, when the crushing roller 310 rotates, it drives the traction disc 313 to rotate, and through the cooperation of the swing arm 309, it pulls the lifting frame 307 to slide up and down back and forth at one end of the feed hopper 302. Then, through the cooperation of the rack 308, it pushes the swing toothed roller 306, the drive rod 304 and the shaking plate 305 to rotate in a forward and reverse cycle, forcing the shaking plate 305 to shake the straw and ingredients inside the crushing channel 301, preventing the straw and ingredients from getting stuck during the feeding process, and ensuring the feeding effect. The crushed straw and ingredients enter the conveying cylinder 314 together, and the conveying motor 316 starts to rotate the conveying auger 317 to convey the straw and ingredients. At the same time, during the conveying process, the straw and ingredients are evenly mixed together, and then enter the dispensing cylinder 319 through the feeding pipe 318. Next, the rotary granulation motor 403 inside the vertical cylinder base 401 is started to rotate, which in turn rotates the rotating material tray 404, the rotating shaft 405 and the rotating support 406. At the same time, because the sealing top cover 321 is connected to the rotating support 406, the sealing top cover 321, the feeding pipe 320 and the distributing cylinder 319 rotate synchronously, forcing the triangular partition plate to rotate, so that the mixture inside the feeding pipe 318 intermittently enters the three feeding pipes 320, and then evenly adds the mixture between the three extrusion rollers 408. The mixture is staggered, which ensures the uniformity of the subsequent extrusion output, and at the same time prevents the mixture from falling onto the extrusion rollers 408 and the rotating support 406, preventing the extrusion rollers 408 from jamming and being damaged. Next, when the mixture enters the rotating material plate 404 inside the annular granulation cylinder 402, the material scraper 409 driven by the rotating shaft 405 pushes the mixture to be gathered on the inner wall of the annular die cylinder 410. Then, the rotating bracket 406 rotates the extrusion roller 408 to contact the mixture and pushes the extrusion roller 408 to rotate by friction, extruding the mixture accumulated on the inner wall of the annular die cylinder 410 and squeezing it through the mesh of the inner wall of the annular die cylinder 410. During the rotation of the rotating material tray 404, the positioning knife holder 411 carries the inclined scraper 412 to slide along the outside of the ring die cylinder 410, cutting the extruded strip fertilizer into small pieces. At the same time, the cut fertilizer generates centrifugal force as it rotates on the rotating material tray 404, and is pushed by the cutter to the inner wall of the ring granulation cylinder 402. When it rotates to the discharge channel 416, it is thrown out and falls into the vibrating screen 418 for screening. The finished fertilizer particles enter the receiving box 424 through the vibrating screen 418, while the broken fertilizer particles are screened off, slide along the discharge channel 416, and are discharged from the waste discharge trough for classified collection. This makes it convenient to put the broken fertilizer particles back into the feed hopper 302 for crushing and granulation again, reducing material waste. In addition, the cooperation of the transmission wheel 422 and the internal toothed belt 423 facilitates the rotation of the cam 421 driven by the rotary granulation motor 403, thereby intermittently pushing the swing frame 419 and the shaking top rod 417 to move, and through the cooperation of the tension spring 420, the shaking screen 418 swings back and forth inside the discharge channel 416, improving the screening effect. Finally, when the number of extruded strip-shaped granules changes, the rotation of the granulation motor 403 is stopped, and the fine-tuning screw 414 is rotated to move along the inner wall of the screw connecting seat 415, thereby pulling the adjusting slider 413, the leveling slide plate 407 and the extrusion roller 408 to slide along the inner wall of the rotating bracket 406, changing the distance between the extrusion roller 408 and the ring die cylinder 410, and ensuring the effect of continuous extrusion.
