Description

Technical Field

[0001] This utility model relates to the field of pelletizing equipment technology, specifically a biomass pellet fuel pelletizing device. Background Technology

[0002] A granulation unit is a mechanical device used to process powdery, pasty, or molten materials into granular products. It is widely used in the food, pharmaceutical, chemical, and feed industries. Through specific processes such as extrusion, rollers, nozzles, or rotation, it shapes and cuts raw materials into uniform granules to improve the material's flowability, solubility, storage stability, or facilitate subsequent processing and packaging. Granulation units come in various designs, including rotary granulators, extrusion granulators, and fluidized bed granulators. The appropriate model can be selected according to the characteristics of different materials and production needs to achieve efficient, continuous, or batch granulation production.

[0003] A biomass pellet fuel pelletizing device is a specialized device designed to process biomass raw materials such as agricultural waste (such as straw, sawdust, and rice husks) or forestry residues into high-density, easy-to-store, and easily transportable pellet fuel. This device typically includes systems for raw material pretreatment, feeding, pelletizing (by extrusion using rollers or flat molds), pellet cooling, screening, and packaging. The core of this process lies in the pelletizing stage, where high temperature and pressure soften lignin and other components in the biomass, acting as a binder to shape powdery or fragmented raw materials into dense, highly efficient cylindrical or spherical pellets. This pellet fuel not only has a high calorific value but also relatively low pollutant emissions during combustion, making it an important piece of equipment for realizing the resource utilization of biomass energy and clean heating.

[0004] However, existing biomass pellet fuel pelleting devices, especially those with traditional fixed connections, suffer from uneven raw material pressure, reduced pelleting efficiency, inconsistent pellet quality, inconsistent roller speeds, uneven raw material forming, and reduced pellet density and strength. Furthermore, the filter barrel's pores are easily clogged by the raw material, increasing maintenance costs and downtime, thus impacting production efficiency. To address these issues, a new biomass pellet fuel pelleting device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a biomass pellet fuel pelletizing device that solves the problems in the prior art of not being able to accurately and stably achieve pelletizing, not being able to ensure stability during the pelletizing process, and not being able to prevent filter clogging during the pelletizing process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biomass pellet fuel pelletizing device, comprising a processing platform, a connecting frame fixedly connected to the top center of the processing platform, fixing blocks fixedly connected to both ends of the top of the connecting frame, a servo motor fixedly connected to one side of one end of the fixing block, the output end of the servo motor passing through the fixing block and fixedly connected to a worm gear, the worm gear being rotatably connected to the fixing block, a rotating rod passing through and rotatably connected between the fixing blocks, a worm wheel passing through and fixedly connected to one end of the outer ring of the rotating rod, the worm wheel being meshed with the worm gear, a first synchronous pulley fixedly connected to both ends of the rotating rod, a first gear passing through and rotatably connected to the middle of both ends of the inner wall of the connecting frame, a second gear passing through and rotatably connected to the top of both ends of the inner wall of the connecting frame, the second gear being meshed with the first gear, a filter barrel provided at one end of the first gear, the filter barrel being rotatably connected to the connecting frame, a transmission assembly provided on the inner wall of the connecting frame, and disassembly assemblies provided on both sides of the top of the processing platform.

The second pressure roller is rotatably connected to the first gear, and the second pressure roller is in contact with the filter barrel.

[0009] By adopting the above technical solution, the linkage between the components can ensure that the rotation speed of the two pressure rollers is consistent, so that the raw material is uniformly squeezed in the filter barrel, avoiding the problem of uneven raw material forming caused by different pressure roller rotation speeds, and further improving the quality of the particles.

[0010] As a further description of the above technical solution: a brush roller is fixedly connected to one end of the second gear, and the brush roller is rotatably connected to the connecting frame. The brush roller is in contact with the filter barrel. A first spring is uniformly distributed inside the brush roller. A pressure block is fixedly connected to one end of each first spring, and the pressure block is slidably connected to the brush roller. The pressure block is in contact with the filter barrel.

[0011] By adopting the above technical solution and through the linkage between the above components, the filter barrel holes can be effectively prevented from being blocked by raw materials, ensuring that the raw materials can be smoothly discharged from the holes and avoiding the problem of reduced granulation efficiency due to hole blockage.

[0012] As a further description of the above technical solution: the disassembly assembly includes a connecting plate, which is slidably connected to the top two sides of the processing platform, and is slidably connected to the connecting frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0028] Reference Figure 1 and Figure 2 This utility model discloses a biomass pellet fuel pelletizing device, including a processing platform 1. The processing platform 1 can support the necessary equipment and control panel, thereby setting the required processing parameters. A collection box at the bottom of the processing platform 1 collects the produced pellets. A connecting frame 2 is fixedly connected to the top center of the processing platform 1. The connecting frame 2 can support and fix the necessary components and structures. The required raw materials are poured into the filter bucket 13 through a feed pipe at one end of the connecting frame 2. Fixing blocks 3 are fixedly connected to both ends of the top of the connecting frame 2. The fixing blocks 3 can support and fix the required servo motor 4. A servo motor 4 is fixedly connected to one side of one end of the fixing block 3. The servo motor 4 allows the worm gear 5 to rotate on the fixed block 3. A filter barrel 13 is provided at one end of the first gear 12, and the filter barrel 13 is rotatably connected to the connecting frame 2. The filter barrel 13 can carry the required raw materials. A transmission component is provided on the inner wall of the connecting frame 2. Disassembly components are provided on both sides of the top of the processing platform 1. Filter plates 20 are provided at both ends of the inner wall of the connecting frame 2. The filter plates 20 can block the produced particles, making them easy to collect. Scrapers 7 are provided on both sides of the bottom of the inner wall of the connecting frame 2, and the scrapers 7 are in contact with the filter barrel 13. The scrapers 7 can cut the extruded strip-shaped raw materials to form particles, and can scrape the residual raw materials from the outer wall of the filter barrel 13.

[0029] Reference Figure 2 and Figure 3The output end of the servo motor 4 passes through the fixed block 3 and is fixedly connected to a worm gear 5, which is rotatably connected to the fixed block 3. A rotating rod 6 passes through and is rotatably connected between the fixed blocks 3. One end of the outer ring of the rotating rod 6 passes through and is fixedly connected to a worm wheel 8, which meshes with the worm gear 5. Both ends of the rotating rod 6 are fixedly connected to a first synchronous pulley 9. A first gear 12 passes through and is rotatably connected to the middle of both ends of the inner wall of the connecting frame 2. A second gear 17 passes through and is rotatably connected to the top of both ends of the inner wall of the connecting frame 2, and the second gear 17 meshes with the first gear 12. The transmission assembly includes a first pressure roller 14, which is rotatably connected to one end of the inner wall of the connecting frame 2. The first pressure roller 14 is rotatably connected to a first gear 12 and contacts the filter barrel 13. A second synchronous pulley 11 is fixedly connected to one end of the first pressure roller 14, and the second synchronous pulley 11 is fixedly connected to the other end of the first gear 12. A synchronous belt 10 is provided between the second synchronous pulley 11 and the first synchronous pulley 12. A second pressure roller 15 is rotatably connected to one end of the inner wall of the connecting frame 2, and the second pressure roller 15 is connected to the first pressure roller 14. The second pressure roller 15 is rotatably connected to the first gear 12, and the second pressure roller 15 contacts the filter barrel 13. The rotation of the worm gear 5 causes the worm wheel 8 to drive the rotating rod 6 to rotate between the fixed blocks 3, thereby causing the first synchronous pulleys 9 at both ends to rotate. Subsequently, through the transmission of the synchronous belt 10, the second synchronous pulley 11 rotates, causing the first gear 12 and the first pressure roller 14 to rotate synchronously, thus causing the second pressure roller 15 to rotate. This ensures the stability and precision of the granulation process. One end of the second gear 17 is fixedly connected to a brush roller 16, and the brush... Roller 16 is rotatably connected to connecting frame 2. Brush roller 16 contacts filter barrel 13. The inside of brush roller 16 is provided with evenly distributed first springs 18. One end of each first spring 18 is fixedly connected to a pressure block 19, and the pressure block 19 is slidably connected to brush roller 16. The pressure block 19 contacts filter barrel 13. Through the rotation of first gear 12, second gear 17 rotates on connecting frame 2, thereby driving brush roller 16 to rotate, so that pressure block 19 slides into brush roller 16, thereby squeezing first spring 18, thus avoiding the problem of reduced granulation efficiency due to hole blockage.

[0030] Reference Figure 2 and Figure 4The disassembly assembly includes a connecting plate 21, which is slidably connected to the top two sides of the processing platform 1. The connecting plate 21 is also slidably connected to the connecting frame 2. A fan 23 is installed on one side of the connecting plate 21, and a filter screen 22 is installed on the other side. Driven by the fan 23, dust present in the connecting frame 2 and connecting plate 21 is extracted and blocked by the filter plate 20 and filter screen 22, effectively reducing dust concentration in the working environment, improving working conditions, and protecting the respiratory health of operators. Fixed rods 24 are slidably connected to both sides of one end of the processing platform 1, and these fixed rods 24 are slidably connected to the connecting plate 21. Each fixed rod 24 has a support rod 25 that is slidably connected through it to the top. The support rod 25 is also slidably connected through it to the processing platform 1. One end of each support rod 25 is connected through it and fixedly to a second spring 26. One end of each second spring 26 is fixedly connected to a limit rod 27, which is slidably connected through it to the processing platform 1. By allowing the limit rod 27 to slide into the support rod 25, the second spring 26 is compressed, causing the support rod 25 to slide out of the processing platform 1 and the fixed rod 24. This causes the fixed rod 24 to slide out of the processing platform 1 and the connecting plate 21, and finally, the connecting plate 21 to slide out of the processing platform 1. This allows the system to adapt to different dust handling needs and improve the adaptability of the equipment.

[0031] Working principle: The connecting plate 21 slides into the processing platform 1 and contacts the connecting frame 2. Then, the fixing rod 24 slides into the processing platform 1 and passes through the connecting rod fixed at the bottom of the connecting plate 21. Then, the limiting rod 27 slides into the support rod 25, thereby compressing the second spring 26. Then, the support rod 25 slides into the processing platform 1 and into the fixing rod 24. At the same time, the bearing rod set on one side of the bottom of the support rod 25 passes through the processing platform 1, thereby further limiting the position. Then, due to the rebound of the second spring 26, the limiting rod 27 slides out of the support rod 25 and slides into the processing platform 1, thereby fixing and limiting the connecting plate 21 as needed. Then, through the rotation of the worm gear 5 and the meshing connection between the worm gear 5 and the worm wheel 8, the worm wheel 8 drives the rotating rod 6 to rotate between the fixed blocks 3, thereby driving the first synchronous pulleys 9 at both ends to rotate. Then, through the transmission of the synchronous belt 10, the rotation of the first synchronous pulleys 9 at both ends is driven. The second synchronous pulley 11 rotates synchronously, causing the first gear 12 and the first pressure roller 14 to rotate synchronously. Then, through the meshing connection between the first pressure roller 14 and the second pressure roller 15, the second pressure roller 15 rotates inside the filter barrel 13. Subsequently, through the meshing connection between the first gear 12 and the second gear 17, the second gear 17 drives the brush roller 16 to rotate on the connecting frame 2, causing the pressure block 19 to slide into the hole on the filter barrel 13 and into the brush roller 16, thereby squeezing the first spring 18. Then, through the rebound of the first spring 18, the pressure block 19 cleans the hole of the filter barrel 13. At the same time, driven by the fan 22, the dust generated during the processing is extracted and blocked by the filter screen 23, ensuring that the dust is collected on the inner wall of the connecting plate 21. The collected dust can be cleaned by the sliding plate set at the bottom of one side of the connecting plate 21.
