TECHNICAL FIELD

[0001] The application relates to the technical field of biomass fuel processing, in particular to a biomass fuel raw material processing production line and a processing technology. BACKGROUND

[0002] Biomass fuel refers to straw, weeds, wood chips, shrub branches and even fruit shells and peels, etc. agricultural and forestry waste compressed into high-density combustion particles. These agricultural and forestry wastes have high combustion values and are a kind of clean energy resources.

[0003] In the prior art, after the raw materials are crushed, the crushed raw materials need to be moved into the drying cylinder for dehydration. However, the drying cylinder needs to be stopped before and after drying, so that the raw materials can be fed and discharged, which greatly affects the processing efficiency. Therefore, the biomass fuel raw material processing production line and the processing technology are used to solve the technical problem. SUMMARY

[0004] In view of the deficiencies in the prior art, the application aims to provide a biomass fuel raw material processing production line and a processing technology to solve the technical problems in the background art.

[0005] The above-mentioned purpose of the application is achieved by the following technical scheme: a biomass fuel raw material processing production line, comprising a crushing assembly and a drying cylinder installed at the bottom of the crushing assembly, a driving assembly for pushing the raw materials is arranged in the drying cylinder, and a heating assembly is further arranged at the bottom of the drying cylinder.

[0006] By adopting the above-mentioned technical scheme, the crushing assembly is directly installed at the top of the drying cylinder, forming a compact integrated structure, effectively reducing the material transfer link and the site occupation. The driving assembly arranged in the drying cylinder realizes the mechanical propulsion of the materials during the drying process, ensuring the continuity and stability of the processing flow. At the same time, the layout of the heating assembly at the bottom enables the heat source to directly and efficiently act on the materials, significantly improving the heat energy utilization rate and the drying efficiency. The overall design simplifies the operation process, reduces the equipment investment and the operation cost.

[0007] Further, the crushing assembly comprises a crushing box, a pair of crushing shafts are rotatably arranged in the crushing box, crushing teeth are fixedly arranged on the shafts of the crushing shafts, a connecting plate is fixedly arranged on the crushing box, a driving motor is fixedly arranged on the connecting plate, a reducer is fixedly arranged on the output end of the driving motor, the output end of the reducer is fixedly connected with one of the crushing shafts, driving gears that are mutually engaged are further fixedly connected to the ends of the two crushing shafts, and a guide assembly is arranged at the upper end of the crushing box.

[0008] By adopting the above technical scheme, the high efficiency and strong shearing and crushing of the raw materials are realized through a pair of crushing shafts provided with crushing teeth and meshing with each other, and the uniformity of material crushing is ensured. Stable power is provided by the driving motor through the speed reducer, and the precise synchronous reverse rotation of the two crushing shafts is ensured by using the driving gears at the ends which mesh with each other, which not only greatly improves the crushing efficiency and avoids material jamming, but also ensures the stability and reliability of power transmission. The whole assembly has compact structure and high integration, and provides uniform material basis for the subsequent drying process.

[0009] Further, the drying cylinder is connected to the crushing box on one side, and the driving assembly comprises a heated cylinder arranged in the drying cylinder, a driving shaft arranged in the heated cylinder, and a driving threaded strip fixedly connected to the outer side of the driving shaft. The crushing box is provided with a rotating assembly for driving the driving shaft.

[0010] By adopting the above technical scheme, the smooth flow of the materials from crushing to drying is realized by directly connecting the crushing box and the drying cylinder. The core is that the driving assembly adopts a heated cylinder with a built-in driving shaft and a driving threaded strip. This structure can continuously and uniformly push the materials forward in the drying cylinder, realize dynamic and continuous drying of the materials, and effectively avoid the efficiency bottleneck caused by traditional intermittent operation. The combination of mechanical propulsion and direct heating ensures uniform heating of the materials and stable processing flow.

[0011] Further, the rotating assembly comprises a rotating motor, a connecting seat fixedly connected to the bottom of the connecting plate, and the rotating motor and the connecting seat are fixedly connected. The output end of the rotating motor is fixedly connected with the driving shaft, and the heated cylinder extends to the rotating motor end with a linkage shaft. A linkage ring is fixedly arranged on the end of the linkage shaft, and the linkage ring and the driving shaft are fixedly connected through a fixed rod. The heated cylinder is rotatably connected in the drying cylinder.

[0012] By adopting the above technical scheme, the driving shaft and the heated cylinder on the outside are simultaneously driven to rotate by a rotating motor. The driving threaded strip on the driving shaft is responsible for pushing the materials, and the synchronously rotating heated cylinder makes the cylinder wall itself become a huge heating surface, which can dynamically and uniformly heat the materials, greatly increase the heat contact area and heat exchange efficiency, and effectively prevent the materials from sticking or uneven heating. This design of rigid linkage of the core transmission components and the heating surface driven by the same power source has compact structure, direct and reliable power transmission, and ensures that the whole drying system operates efficiently and stably and continuously.

[0013] Further, the heating assembly comprises a transportation pipeline arranged at the bottom of the drying cylinder, a plurality of heating nozzles fixedly connected to the upper end of the transportation pipeline, and the output end of the heating nozzle faces upward. A through groove for connecting the heating nozzle is formed in the bottom of the drying cylinder.

[0014] By adopting the above technical scheme, the hot air flow is directly sprayed into the material rolling in the cylinder through the conveying pipeline at the bottom of the drying cylinder and the plurality of upwardly arranged heating nozzles. The spraying mode from bottom to top greatly increases the contact area and contact efficiency of the hot air and the material, and can produce a certain blowing and disturbance effect on the material, which cooperates with the driving assembly to ensure that the material is quickly and uniformly heated and dried during the advancing process, thereby significantly improving the overall drying efficiency and energy utilization rate.

[0015] Further, the guide assembly comprises guide shafts rotatably connected at both ends of the crushing box, and guide plates are fixedly arranged on the guide shafts. An adjusting device for driving the guide shafts is arranged on the side surface of the crushing box.

[0016] By adopting the above technical scheme, the guide plates are driven by the rotatable guide shafts to achieve flexible control of the feeding direction and the dropping speed. In cooperation with the adjusting device, the distribution and input amount of the material in the crushing box can be accurately adjusted, the feeding port is effectively prevented from being blocked, and the material is ensured to be uniformly and stably conveyed to the crushing area, thereby optimizing the crushing efficiency and laying a foundation for the smooth operation of the subsequent process.

[0017] Further, the adjusting device comprises a driven gear fixedly connected to one end of the guide shaft, the crushing box is provided with a mesh rack engaged with the driven gear, a driving rod is fixedly arranged at the bottom of the mesh rack, a driving cylinder is fixedly arranged on the crushing box, and the output end of the driving cylinder is fixedly connected with the driving rod.

[0018] By adopting the above technical scheme, the mesh rack is driven by the cylinder to move linearly, and the rotation of the driven gear and the guide shaft is accurately converted. This design realizes rapid, accurate and automatic control of the opening angle of the guide plate, can flexibly adapt to the feeding requirements of different characteristic raw materials, effectively prevents the blocking of the feeding port, and ensures that the material enters the crushing area uniformly and stably, thereby improving the automation degree and operation reliability of the entire crushing process.

[0019] Further, a flexible filler is arranged between the gap between the guide shaft and the crushing line.

[0020] Further, a biomass fuel raw material processing process is applied to the biomass fuel raw material processing production line in any one of the above technical solutions, and comprises the following steps: S1, the raw material is put into the crushing box and subjected to strong shearing and crushing by a pair of synchronously and oppositely rotating crushing shafts; S2, the crushed material directly enters the drying cylinder, the driving shaft inside and the heated cylinder outside are synchronously rotated by the rotating motor, and the thread strips on the driving shaft continuously push the material forward. S3. During the propulsion process, the rotating heated cylinder wall acts as the heating surface to uniformly conduct heat to the material, while the bottom heating nozzles spray hot air upwards to achieve efficient convection heating. S4. The dried material is continuously discharged from the discharge end and enters the next process.

[0021] By adopting the above technical solution, this processing technology seamlessly integrates high-efficiency crushing and continuous drying, achieving a high degree of automation and continuity in the production process. Its core benefits are reflected in the following aspects: First, significantly improved efficiency. The synchronously rotating drive shaft and heated cylinder design, combined with bottom hot air jets, allow the material to receive both conductive and convective heating during the process, achieving dynamic, uniform, and efficient drying. This completely eliminates downtime associated with traditional intermittent operations, significantly increasing output per unit time. Second, energy saving, consumption reduction, and quality improvement. The compact integrated design reduces material transfer and heat loss, while the rotating heated cylinder ensures uniform heating of the material, effectively avoiding localized overheating or sticking. This improves heat utilization while ensuring the consistency and stability of the dried material's quality. Third, reliable operation and cost optimization. The entire process is mechanically automated, with direct and reliable power transmission. This not only reduces the intensity and intervention of manual operation but also simplifies equipment maintenance, thereby comprehensively reducing equipment investment and operating costs.

[0022] In summary, this application includes the following beneficial technical effects: through the direct docking design of the crushing component and the drying cylinder, and the synergistic effect of the drive screw and the rotating heated cylinder, the entire process of material feeding, crushing to drying and discharging can be completed without interruption, which completely solves the problem of downtime and waiting caused by batch operation of traditional equipment and greatly improves production efficiency.

[0023] The method combines conductive heating from a rotating heating cylinder with convective heating from a bottom nozzle, ensuring full contact between the heat source and the material. The synchronously rotating heating cylinder participates in both propulsion and serves as a heating surface, increasing the heat exchange area and efficiency while significantly reducing energy consumption.

[0024] The guide plate angle is precisely controlled by a gear and rack mechanism driven by a cylinder. Combined with flexible sealing materials, it can adapt to raw materials with different characteristics and effectively prevent blockage and dust leakage, providing a stable and uniform material supply for subsequent processes.

[0025] The direct integration of the crushing and drying modules reduces intermediate conveying links, lowers equipment investment and floor space requirements, simplifies the operation process, and reduces energy loss during the transfer process.

[0026] The synchronous design of the drive shaft propulsion and the rotation of the heated cylinder ensures that the material is constantly turned over and propelled during the drying process, avoiding local overheating or sticking, ensuring uniform heating and consistent drying of the material, and ultimately resulting in stable and reliable product quality.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] Example, refer to Figure 1 A biomass fuel raw material processing production line includes a crushing component and a drying cylinder 3 installed at the bottom of the crushing component. The drying cylinder 3 is equipped with a drive component for moving the raw material, and a heating component is also installed at the bottom of the drying cylinder 3.

[0031] By directly mounting the crushing components to the top of the drying cylinder 3, a compact, integrated structure is formed, effectively reducing material transfer links and space occupation. The internal drive components of the drying cylinder 3 enable mechanical propulsion of the material during the drying process, ensuring the continuity and stability of the processing flow. Simultaneously, the layout of the bottom heating components allows the heat source to act directly and efficiently on the material, significantly improving heat energy utilization and drying efficiency. The overall design simplifies the operation process and reduces equipment investment and operating costs.

[0032] The crushing assembly includes a crushing box 1, inside which a pair of crushing shafts 11 are rotatably mounted. Crushing teeth 12 are fixedly mounted on the shaft of each crushing shaft 11. A connecting plate 10 is fixedly mounted on the crushing box 1, and a drive motor 14 is fixedly mounted on the connecting plate 10. A reducer 15 is fixedly mounted on the output end of the drive motor 14. The output end of the reducer 15 is fixedly connected to one of the crushing shafts 11. The ends of the two crushing shafts 11 are also fixedly connected to meshing drive gears 13. A guide assembly is provided at the upper end of the crushing box 1.

[0033] A pair of meshing crushing shafts 11 equipped with crushing teeth 12 achieve efficient and powerful shearing and crushing of the raw materials, ensuring the uniformity of material crushing. A drive motor 14 provides stable power through a reducer 15, and the meshing drive gears 13 at their ends ensure precise synchronous counter-rotation of the two crushing shafts 11. This not only greatly improves crushing efficiency and avoids material jamming, but also ensures smooth and reliable power transmission. The entire assembly has a compact structure and high integration, providing a uniform material base for subsequent drying processes.

[0034] The drying cylinder 3 is connected to the crushing box 1 on one side. The driving assembly includes a heating cylinder 33 disposed inside the drying cylinder 3. A driving shaft 31 is disposed inside the heating cylinder 33. A driving threaded strip 32 is fixedly connected to the outside of the driving shaft 31. A rotating assembly for driving the driving shaft 31 is disposed on the side of the crushing box 1.

[0035] By directly connecting the crushing chamber 1 to the drying cylinder 3, a smooth flow of materials from crushing to drying is achieved. The core of this system lies in the drive assembly, which employs a heated cylinder 33 with a built-in drive shaft 31 and drive threaded strip 32. This structure continuously and evenly propels the material forward within the drying cylinder 3, achieving dynamic and continuous drying. This effectively avoids the efficiency bottleneck caused by traditional intermittent operation. This combination of mechanical propulsion and direct heating ensures uniform heating of the material and a consistent and stable processing flow.

[0036] The rotating assembly includes a rotating motor 36, a connecting seat 37 fixedly connected to the bottom of the connecting plate 10, the rotating motor 36 and the connecting seat 37 are fixedly connected, the output end of the rotating motor 36 is fixedly connected to the drive shaft 31, the heating cylinder 33 extends a linkage shaft 34 to one end of the rotating motor 36, a linkage ring 35 is fixedly provided on the end of the linkage shaft 34, the linkage ring 35 and the drive shaft 31 are fixedly connected by a fixing rod, and the heating cylinder 33 is rotatably connected inside the drying cylinder 3.

[0037] A single rotating motor 36 simultaneously drives the internal drive shaft 31 and the external heating cylinder 33 to rotate synchronously. The drive threaded bar 32 on the drive shaft 31 propels the material, while the synchronously rotating heating cylinder 33 itself becomes a large heating surface, enabling dynamic and uniform heating of the material. This significantly increases the heat contact area and heat exchange efficiency, effectively preventing material adhesion or uneven heating. This design, which rigidly links the core transmission components to the heating surface and is driven by the same power source, features a compact structure, direct and reliable power transmission, and ensures efficient, stable, and continuous operation of the entire drying system.

[0038] The heating assembly includes a transport pipe located at the bottom of the drying cylinder 3. Multiple heating nozzles 41 are fixedly connected to the upper end of the transport pipe 4. The output ends of the heating nozzles 41 face upwards. A through groove is provided at the bottom of the drying cylinder 3 for connecting the heating nozzles.

[0039] Hot air is directly injected into the tumbling material inside the drying drum through a transport pipe located at the bottom of the drum and multiple upward-facing heating nozzles. This bottom-up injection method greatly increases the contact area and efficiency between the hot air and the material, and also generates a certain blowing and disturbance effect on the material. Working in conjunction with the drive components, it ensures that the material is heated and dried quickly and evenly during the process, thereby significantly improving the overall drying efficiency and energy utilization.

[0040] The guiding assembly includes a guide shaft 2 rotatably connected to both ends of the crushing box 1, a guide plate 21 fixedly mounted on the guide shaft 2, and an adjustment device for driving the guide shaft 2 on the side of the crushing box 1.

[0041] The guide plate 21 is driven by the rotatable guide shaft 2, enabling flexible control of the feeding direction and the feeding speed. Combined with the adjustment device, the distribution and amount of material in the crushing chamber 1 can be precisely adjusted, effectively preventing blockage at the feed inlet and ensuring that the material is uniformly and stably conveyed to the crushing area. This optimizes crushing efficiency, protects the crushing components, and lays the foundation for the smooth operation of subsequent processes.

[0042] The adjusting device includes a driven gear 22 fixedly connected to one end of the guide shaft 2. The crushing box 1 is provided with a rack 23 meshing with the driven gear 22. A driving rod 24 is fixedly provided at the bottom of the rack 23. A driving cylinder 25 is fixedly provided on the crushing box 1. The output end of the driving cylinder 25 is fixedly connected to the driving rod 24.

[0043] The linear motion of the rack 23 driven by the cylinder is precisely converted into the rotational motion of the driven gear 22 and the guide shaft 2. This design enables rapid, precise, and automated control of the opening and closing angle of the guide plate 21, flexibly adapting to the feeding requirements of raw materials with different characteristics, effectively preventing blockage of the feed inlet, and ensuring that the material enters the crushing zone uniformly and stably, thereby improving the automation level and operational reliability of the entire crushing process.

[0044] A flexible filler is provided between the guide shaft 2 and the crushing line.

[0045] A biomass fuel raw material processing technology, applied to a biomass fuel raw material processing production line according to any one of the above technical solutions, includes the following steps: S1. Raw materials are fed into the crushing chamber 1, where they are forcefully sheared and crushed by a pair of synchronously rotating counter-rotating crushing shafts 11; S2. The crushed material directly enters the drying cylinder 3, where the internal drive shaft 31 and the outer heating cylinder 33 are driven to rotate synchronously by a rotating motor 36, and the threaded strip on the drive shaft 31 continuously propels the material forward; S3. During the propulsion process, the wall of the rotating heating cylinder 33 acts as a heating surface to uniformly conduct heat to the material, while the bottom heating nozzle 41 sprays hot air upwards to achieve efficient convection heating; S4. The dried material is continuously discharged from the discharge end and enters the next process.

[0046] This processing technology seamlessly integrates high-efficiency crushing and continuous drying, achieving a high degree of automation and continuity in the production process. Its core benefits are: First, significantly improved efficiency. The synchronously rotating drive shaft 31 and heating cylinder 33, combined with bottom hot air jets, allow the material to receive both conductive and convective heating during the process, achieving dynamic, uniform, and efficient drying. This completely eliminates downtime associated with traditional intermittent operations, significantly increasing output per unit time. Second, energy saving, reduced consumption, and improved quality. The compact integrated design reduces material transfer and heat loss, while the rotating heating cylinder 33 ensures uniform heating of the material, effectively preventing localized overheating or sticking. This improves heat utilization while ensuring the consistency and stability of the dried material's quality. Third, reliable operation and optimized costs. The entire process is mechanically automated, with direct and reliable power transmission. This not only reduces the intensity and intervention of manual operation but also simplifies equipment maintenance, thereby comprehensively reducing equipment investment and operating costs.

[0047] Specific implementation process: First, the feeding preparation stage is carried out. The operator puts the biomass raw materials into the feed inlet above the crushing box 1. At this time, the cylinder 25 starts to work, which drives the rack 23 to move linearly through the drive rod 24. The rack 23 meshes with the driven gear 22, converting the linear motion into rotational motion, thereby driving the guide shaft 2 to rotate. The guide plate 21 fixed on the guide shaft 2 adjusts its angle accordingly, realizing precise control of the feed amount and feed direction. The flexible filler between the guide shaft 2 and the crushing box 1 effectively prevents the leakage of fine materials and the dispersion of dust during this process.

[0048] Next, the crushing stage begins. The drive motor 14 starts, and after the torque is increased by the reducer 15, it drives the active crushing shaft 11 to rotate. The drive gear 13 at the end of this crushing shaft 11 meshes with the drive gear 13 on another crushing shaft 11, ensuring that the two crushing shafts 11 maintain precise synchronous counter-rotation. The crushing teeth 12 installed on the crushing shafts 11 forcefully shear and crush the falling raw material, processing it into uniform, fine particles. The crushed material, under the influence of gravity, falls naturally through the interface between the crushing box 1 and the drying cylinder 3, entering the drying process.

[0049] During the drying stage, the rotating motor 36 starts working, driving the internal drive shaft 31 and the external heating cylinder 33 to rotate synchronously through the transmission of the linkage shaft 34 and the fixed rod 38. The drive threaded bar 32 on the drive shaft 31 continuously pushes the material towards the discharge end, while the rotating heating cylinder 33 heats the material evenly through the cylinder wall. At the same time, the heating components located at the bottom of the drying cylinder 3 start working, delivering hot air to each heating nozzle 41 through the transport pipe. These upward-facing nozzles directly spray hot air into the material, achieving convective heating of the material.

[0050] Finally, there is the discharge stage. After thorough crushing and drying, the material that meets the predetermined standards is continuously discharged from the discharge end of drying cylinder 3. This processed material is then conveyed to the next process, ready for subsequent compression molding and other processing. The entire production process achieves continuous operation from feeding, crushing, drying to discharge, effectively improving production efficiency and quality stability.

[0051] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
