Technical Field

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

[0002] Biomass fuel refers to the combustion of biomass materials as fuel. It mainly involves crushing agricultural and forestry waste such as straw, rice husks, and wood chips, then extruding and plasticizing them to produce environmentally friendly fuel. It can be used as fuel for furnaces, boilers, and power generation furnaces, and in some areas, it can completely replace coal.

[0003] Extrusion molding is a common biomass fuel processing method. It involves compressing biomass raw materials into uniform, dense pellets or blocks using an extruder to improve combustion efficiency and facilitate storage and transportation. However, existing fuel briquetting devices are inconvenient for discharging the extruded fuel blocks, reducing production efficiency. Therefore, we propose a pelletizing device for processing biomass fuel pellets. Utility Model Content

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1 to 4 This utility model provides a technical solution: a pellet biomass fuel processing molding device, including a feeding hopper 9 and a processing hopper 11 coaxially arranged. A support base 22 with a trapezoidal cross-section is tightly fitted inside the feeding hopper 9, and a discharge hopper 3 is obliquely connected to the side wall of the feeding hopper 9. The upper end of the discharge hopper 3 is connected to the bottom of the support base 22. Figure 1 , 2 As shown, the trapezoidal cross-section of the support 22 facilitates the discharge of fuel particles falling on its top, improving the efficiency of fuel falling. The falling fuel particles move to the top of the discharge hopper 3.

[0022] An opening is provided at the bottom of the discharge hopper 3, and a screen 5 is fastened inside it. Under the filtering action of the screen 5, the generated feed scraps can be filtered. The bottom of the screen 5 is provided with a receiving hopper 14 that is fastened to the bottom surface of the discharge hopper 3. The screened scraps fall into the receiving hopper 14 for collection, avoiding waste of raw materials. In order to facilitate the rapid discharge of scraps, a feed pipe 13 is connected to the bottom of the receiving hopper 14. At the same time, a vibrating motor 4 is fixedly connected to the bottom surface of the discharge hopper 3. Under the vibration action of the vibrating motor 4, the rapid discharge of scraps and pellet fuel can be further accelerated, which greatly improves the production efficiency.

[0023] As shown in 3 and 4, during extrusion production, a grinding disc 16 is provided inside the processing hopper 11. The grinding disc 16 has several through holes 25 for material discharge. An annular seat 17 is coaxially connected to the inner wall of the processing hopper 11. The grinding disc 16 is coaxially connected to the top of the annular seat 17. A rotating rod 18 that passes through the grinding disc 16 is rotatably connected to the support seat 22. Multiple rotating shafts 20 are circumferentially fastened to the upper outer wall of the rotating rod 18. A grinding roller 19 that is clearance-fitted with the grinding disc 16 is rotatably connected to the rotating shaft 20.

[0024] Meanwhile, to facilitate the replacement and installation of the grinding roller 19 and the grinding disc 16, a limiting seat 26 is coaxially connected to the upper end of the rotating rod 18. The limiting seat 26 is set through the grinding disc 16, and a mounting seat 15 located on the top of the limiting seat 26 is coaxially set on the rotating rod 18. The end of the rotating shaft 20 is fastened to the outer wall of the mounting seat 15. The upper end of the rotating rod 18 is provided with a threaded section, and a limiting nut 21 is coaxially connected to the threaded section. By disassembling the limiting nut 21, the mounting seat 15 can be installed and removed from the rotating rod 18. This not only makes the structure simple and easy to operate, but also improves the practicality of the device.

[0025] To achieve normal extrusion processing, a drive motor 23 is fastened to the bottom of the support base 22, and gears 2 are coaxially connected to the output end of the drive motor 23 and the bottom of the rotating rod 18, with the gears 2 meshing with each other. Multiple first scrapers 6 are inclinedly connected to the outer wall of the rotating rod 18 along the circumference. The bottom of the first scraper 6 is in clearance fit with the top of the support base 22, and multiple second scrapers 10 are fastened to the outer wall of the rotating rod 18 along the circumference. The top of the second scraper 10 is in clearance fit with the bottom surface of the grinding disc 16. Driven by the drive motor 23, the first scrapers 6 rotate and scrape the top of the support base 22, which can quickly discharge the feed that falls to the top of the support base 22. Under the scraping action of the second scrapers 10, the feed can be quickly formed and segmented.

[0026] In summary, this pellet biomass fuel processing molding device features a conical guide plate 1 fastened to the top of the processing hopper 11 during use, facilitating the rapid descent of raw materials and preventing them from falling, thus greatly simplifying the processing process. To improve the overall stability of the device, a base 8 is fastened to the bottom of the discharge hopper 9, with wheels 12 fastened to the four corners of the base 8, making it easy for users to push and transport the device. The bottom of the discharge hopper 3 is connected to the top of the base 8 via a reinforcing plate 7, which improves the overall structural stability of the device. Additionally, to facilitate user maintenance, an inspection port 24 is provided on the base 8 directly below the discharge hopper 9.
