Description

Technical Field

[0001] This utility model relates to the field of biomass energy processing technology, and in particular to a biomass fuel extrusion molding device. Background Technology

[0002] Biomass fuel, as a renewable energy source, boasts advantages such as wide availability and environmental friendliness, and is playing an increasingly important role in the energy sector. To improve the combustion efficiency and facilitate storage and transportation, biomass fuel is typically processed into pellets of specific shapes and sizes using extrusion molding equipment. As a crucial step in biomass fuel production, the performance and quality of extrusion molding equipment have a decisive impact on the pellet forming effect and production efficiency.

[0003] However, in the practical application of biomass fuel extrusion molding equipment, especially in the core process of installing and disassembling extruded blocks, existing equipment has gradually revealed a series of obvious limitations and technical problems. Taking a compaction device for biomass pellet fuel processing disclosed in application number CN202120433138.6 as an example, existing biomass pellet fuel extrusion molding equipment is inconvenient for installing and disassembling extruded blocks during use.

[0004] Specifically, the design of the aforementioned patent neglects the need for rapid replacement of extruded blocks. This results in a cumbersome and time-consuming process when different specifications or sizes of extruded blocks need to be replaced to accommodate different sizes of pellet fuel. This not only reduces production efficiency and increases operational complexity but also fails to meet the demands of modern production for flexibility and efficiency. More seriously, the inconvenience of installing and removing the extruded blocks can lead to loosening or misalignment during production, affecting the quality and consistency of the pellet fuel and potentially damaging the equipment itself, increasing production costs and risks.

[0005] Therefore, given the shortcomings of existing biomass fuel extrusion molding equipment in terms of installing and disassembling extruded blocks, we urgently need a new biomass fuel extrusion molding device to solve this problem. This device should facilitate the rapid installation and disassembly of extruded blocks, improving production efficiency and flexibility, while ensuring the molding quality of pellet fuel and the safe and stable operation of the equipment, thus providing strong support for the sustainable development of the biomass fuel processing industry.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] Example 1

[0028] Please see Figure 1-5 As shown, a biomass fuel extrusion molding apparatus according to this embodiment includes a processing table 1 and a mounting frame 2;

[0029] A forming frame 4 is detachably connected to the top center of the processing table 1. The mounting frame 2 is connected to the top of the processing table 1, and connecting cylinders 6 are provided on both sides of the inside of the mounting frame 2.

[0030] The top of the forming frame 4 is provided with a pressure plate 3, and the top two sides of the pressure plate 3 are connected with connecting columns 7. The inside of the connecting cylinder 6 is slidably connected with a movable column. The top of the movable column is elastically connected to the inner wall of the connecting cylinder 6 through an elastic element. The top end of the connecting column 7 and the bottom end of the movable column are detachably connected.

[0031] Both connecting cylinders 6 are connected to the top of the mounting frame 2 via a vertical lifting structure.

[0032] First, the main body of the device consists of a processing table 1 and a mounting frame 2. The forming frame 4 is detachably connected to the top center of the processing table 1, which is the core component of the entire extrusion molding process. The mounting frame 2 is stably installed on the top of the processing table 1, and connecting cylinders 6 are provided on both sides inside to provide support for the subsequent lifting and lowering of the pressure plate 3.

[0033] When the molding process begins, the pressure plate 3 is placed on top of the molding frame 4, and connecting posts 7 are connected to both sides of the top of the pressure plate 3. The top ends of these connecting posts 7 are detachably connected to the bottom ends of the moving posts inside the connecting cylinder 6, while the moving posts slide inside the connecting cylinder 6, and their tops are elastically connected to the inner wall of the connecting cylinder 6 through elastic elements. This design not only ensures the stability of the pressure plate 3 during the descent process, but also allows the pressure plate 3 and its connecting components to be easily separated from the molding frame 4 when it is necessary to replace it.

[0034] Both connecting cylinders 6 are connected to the top of the mounting frame 2 via a vertical lifting structure. This structure is responsible for driving the pressure plate 3 to move up and down, thereby achieving the extrusion molding of biomass materials. In specific operation, when the biomass material is placed into the molding frame 4, the vertical lifting structure is activated, driving the moving column and pressure plate 3 inside the connecting cylinder 6 to move downward, applying pressure to the material and gradually molding it into pellet fuel of a specific shape and size.

[0035] After extrusion molding is completed, the vertical lifting structure moves in the opposite direction, causing the pressure plate 3 to rise. At this point, due to the detachable connection design between the connecting column 7 and the moving column, the user can easily remove the pressure plate 3 and replace it with a pressure plate 3 of a different size to meet the production needs of different pellet fuels. The entire installation and disassembly process is quick and easy, greatly improving production efficiency and flexibility.

[0036] Example 2

[0037] Please see Figure 1-5 As shown in this embodiment, a biomass fuel extrusion molding device has a base plate 9 fixedly connected to the bottom end of a connecting column 7, and a top plate 8 fixedly connected to the top end. The base plate 9 is bolted to the top of the pressure plate 3. The vertical lifting structure includes a hydraulic cylinder 5 connected to the top of the mounting frame 2. The output end of the hydraulic cylinder 5 is connected to the end of the connecting cylinder 6. Specifically, during device assembly, the base plate 9 is first fixed to the top of the pressure plate 3 with bolts, and then the bottom end of the connecting column 7 is connected to the base plate 9, and the top end is fixed to the top plate 8. When the pressure plate 3 needs to be replaced, the bolts between the base plate 9 and the pressure plate 3 can be easily loosened to separate the pressure plate 3 from the connecting column 7. This design makes the connection between the pressure plate 3 and the connecting column 7 more stable, and allows for quick disassembly when replacing the pressure plate 3, improving production efficiency and ease of operation.

[0038] A docking column 16 is fixedly connected to the top center of the top plate 8. A magnet is connected to the top of the docking column 16, and a docking hole 12 is opened at the bottom center of the moving column. A magnet plate is connected to the top of the inner cavity of the docking hole 12. Specifically, during the descent of the pressure plate 3, the compression spring 14 is compressed, providing a certain buffering effect; when the pressure plate 3 rises, the compression spring 14 returns to its original shape, helping the pressure plate 3 to quickly return to its original position. The design of the compression spring 14 not only ensures the stability of the pressure plate 3 during the descent process, but also reduces impact and vibration, extending the service life of the equipment.

[0039] Both sides of the bottom of the top plate 8 are provided with positioning screws 15, one end of which is threaded through the top plate 8. Both sides of the bottom of the moving column are provided with screw holes 13 that are adapted to the positioning screws 15. Specifically, when the connecting column 7 and the moving column are connected, the magnetic block on the connecting column 16 attracts the magnetic plate in the connecting hole 12, so that the connecting column 7 can be quickly and accurately inserted into the connecting hole 12. The magnetic connection design makes the connection process between the connecting column 7 and the moving column faster and more convenient, improving the assembly and disassembly efficiency of the equipment.

[0040] Example 3

[0041] Please see Figure 1-5 As shown in this embodiment, a biomass fuel extrusion molding apparatus uses a compression spring 14 as the elastic element. One end of the compression spring 14 is connected to the top of the moving column, and the other end is elastically connected to the inner wall of the connecting cylinder 6. Specifically, when the biomass material is placed into the molding frame 4, the hydraulic cylinder 5 is activated, and its output end pushes the connecting cylinder 6 and the internal moving column downward, thereby driving the pressure plate 3 to apply pressure to the material. After extrusion molding is completed, the hydraulic cylinder 5 moves in the opposite direction, driving the pressure plate 3 to rise. The introduction of the hydraulic cylinder 5 provides a stable and powerful power source, making the lifting and lowering movement of the pressure plate 3 more stable and accurate, thus improving the extrusion molding effect and production efficiency.

[0042] Both sides of the connecting cylinder 6 are provided with sliding grooves 10, and both sides of the moving column are fixedly connected with sliders 11 that are slidably connected to the sliding grooves 10. Specifically, when the connecting column 7 is connected to the moving column, the positioning screw 15 is tightened to secure it to the screw hole 13; at the same time, the slider 11 slides in the sliding groove 10, guiding the moving column to move stably up and down within the connecting cylinder 6. The threaded connection between the positioning screw 15 and the screw hole 13 and the sliding connection between the slider 11 and the sliding groove 10 together enhance the connection stability between the connecting column 7 and the moving column and the sliding stability of the moving column, thereby improving the overall performance and reliability of the equipment.

[0043] This solution includes the following work process:

[0044] The main body of the device consists of a processing table 1 and a mounting frame 2. The forming frame 4 is detachably connected to the top center of the processing table 1. This is the core component of the entire extrusion molding process, used to hold biomass materials and shape them. The mounting frame 2 is stably installed on the top of the processing table 1, and connecting cylinders 6 are provided on both sides inside to provide support for the subsequent lifting and lowering of the pressure plate 3.

[0045] During device assembly, the base plate 9 is first fixed to the top of the pressure plate 3 with bolts. Then, the bottom end of the connecting column 7 is connected to the base plate 9, and the top end is fixed to the top plate 8. A docking column 16 is fixedly connected to the center of the top of the top plate 8, and a magnet is connected to the top of the docking column 16. A docking hole 12 is opened at the center of the bottom of the moving column, and a magnet plate is connected to the top of the inner cavity of the docking hole 12. At the same time, sliding grooves 10 are opened on both sides of the connecting cylinder 6, and sliders 11 that are slidably connected to the sliding grooves 10 are fixedly connected to both sides of the moving column. The elastic element is a compression spring 14, one end of which is connected to the top of the moving column, and the other end is elastically connected to the inner wall of the connecting cylinder 6. Both connecting cylinders 6 are connected to the top of the mounting frame 2 through a vertical lifting structure. This vertical lifting structure includes a hydraulic cylinder 5 connected to the top of the mounting frame 2, and the output end of the hydraulic cylinder 5 is connected to the end of the connecting cylinder 6.

[0046] When the molding process begins, the biomass material is first placed into the molding frame 4. Then, the hydraulic cylinder 5 is activated, and its output end pushes the connecting cylinder 6 and the internal moving column downwards. Since the top of the connecting column 7 is detachably connected to the bottom of the moving column—specifically, the magnet on the docking column 16 attracts the magnet in the docking hole 12, and the positioning screw 15 is tightened and securely connected to the screw hole 13—the descent of the moving column causes the pressure plate 3 to descend along with it, applying pressure to the biomass material in the molding frame 4. During this process, the slider 11 slides within the groove 10, guiding the moving column to move stably up and down within the connecting cylinder 6. Simultaneously, the compression spring 14 is compressed, providing a certain buffering effect and ensuring the stability of the pressure plate 3 during descent.

[0047] As the hydraulic cylinder 5 continues to push, the biomass material is gradually shaped into pellet fuel of a specific shape and size under the pressure of the pressure plate 3. After extrusion molding is completed, the hydraulic cylinder 5 moves in the reverse direction, driving the connecting cylinder 6 and the internal moving column upward. Due to the restoring effect of the compression spring 14, the pressure plate 3 is assisted to quickly return to its original position. At this time, due to the detachable connection design between the connecting column 7 and the moving column, the fastening connection between the connecting column 7 and the moving column can be released simply by loosening the positioning screw 15. At the same time, the magnetic attraction between the magnet block and the magnet plate is also easily overcome. Users can easily remove the pressure plate 3 and replace it with a pressure plate 3 of different specifications or sizes to meet the production needs of different pellet fuels.
