Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of pelletizers, in particular to a pelletizing and molding machine for producing biomass pellet fuel. Background Art
[0002] With the continuous development of the global economy, energy and environmental issues are becoming increasingly prominent. The main energy sources currently used by humanity are oil, natural gas, and coal. However, fossil resources such as coal and oil are becoming increasingly depleted and non-renewable, leading to a continuously tight energy supply. Furthermore, the overuse of fossil resources has caused increasingly serious environmental problems. Biomass energy is solar energy stored in plants through photosynthesis. It is estimated that the annual energy stored in plants is equivalent to 10 times the amount consumed by major fuels worldwide, yet less than 1% of this energy is used as energy. As the fourth largest energy resource, biomass holds a crucial position among renewable energy sources. Developing biomass energy can not only supplement the shortage of conventional energy but also has significant environmental benefits. Compared to other biomass energy technologies, biomass pellet fuel technology is easier to achieve large-scale production and use, and its ease of use is comparable to that of gas, oil, and other energy sources. The production of pellet fuel using biomass compacting equipment complies with national industrial policies and offers significant economic and social benefits.
[0003] In the biological granulators in the prior art, the gap between the pressure roller and the ring die is mostly fixed, and cannot be effectively adjusted according to the characteristics of the raw materials and production requirements during operation. In the granulation process, if the gap between the pressure roller and the ring die is too large, the material layer in the granulation area will become thicker, increasing its pressure. At the same time, it will cause the motor current to increase, the resistance of the pressure roller operation to increase, the pressure roller will slip, and the pellet machine will vibrate, resulting in a decrease in granulation output or even no pellets. If the gap is too small, the pressure roller is in direct contact with the ring die, which increases wear and seriously affects the service life. In addition, the ring die guide port will be deformed due to wear, the grinding hole will make feeding difficult, and the granulation output will gradually decrease, resulting in difficulty in pelleting or even suspension of production.

[0031] Among them, the discharging assembly includes a concave ring 27, the concave ring 27 is fixedly connected to the inside of the molding chamber 3, a second drive motor 28 is fixedly connected to one side of the top of the molding chamber 3, the output end of the second drive motor 28 is fixedly connected to the fourth rotating shaft 29, one end of the fourth rotating shaft 29 is fixedly connected to the fifth gear 30, one side of the fifth gear 30 is meshed with the first gear ring 31, the first gear ring 31 is movably sleeved with a ring die 32, the first gear ring 31 is rotatably connected to the inside of the concave ring 27, the fourth rotating shaft 29 is rotatably connected to the concave ring 27, the bottom of the first gear ring 31 is fixedly connected to a cutting knife 33, the blade of the cutting knife 33 is tangent to the outer surface of the ring die 32, and the discharging assembly The component also includes a first gear ring 31, which is meshed and connected to one side of the fifth gear 30.

The rotation of the first gear ring 31 drives the cutting knife 33 to rotate along the outer surface of the ring die 32 to cut the extruded biomass particles, thereby completing the processing of the biomass particles. At the same time, the rotation of the cutting knife 33 can also push the cut biomass particles to be discharged, increase the discharge speed, and improve work efficiency.
[0032] Among them, the width of the chute 20 can be covered by the pressure roller 16, the shape of the cleaning plate 23 is 7-shaped, and the bottom of the cleaning plate 23 has a cutout. By setting the cleaning plate 23 to be 7-shaped, its up and down displacement can be limited.

[0035] Working principle:
[0036] When biomass processing is needed, the raw biomass material is placed into the interior of the forming chamber 3 through the feed port 4. At this time, the raw biomass material will fall onto the surface of the mounting plate 25 due to gravity, and the first drive motor 6 is started. The first drive motor 6 starts to drive the first shaft 7 to rotate, and the first shaft 7 rotates to drive the first gear 8 and the second gear 9 to rotate, and the second gear 9 rotates to drive the second shaft 10, the third gear 11 and the fourth gear 12 to rotate, and the fourth gear 12 rotates to drive the third shaft 13 to rotate, and the third shaft 13 rotates to drive the connecting plate 14 to rotate, and the connecting plate 14 rotates to drive the connecting shaft 15 and the pressure roller 16 to rotate, and the raw biomass material is ground and extruded through the cooperation of the pressure roller 16 and the ring die 32 to be processed into biomass particles. During the processing, According to the characteristics of the biomass material, it is necessary to adjust the gap between the pressure roller 16 and the ring die 32 to adapt to the characteristics of different materials. At this time, the dual-axis motor 17 is started, and the dual-axis motor 17 starts to drive the threaded rod 18 to rotate. The rotation of the threaded rod 18 drives the threaded sleeve 19 to move. The movement of the threaded sleeve 19 drives the connecting shaft 15 to move. The movement of the connecting shaft 15 drives the pressure roller 16 to move, thereby adjusting the gap between the pressure roller 16 and the ring die 32 to adapt to the characteristics of the biomass material and improve the forming effect. At the same time, it can also effectively avoid the gap between the pressure roller 16 and the ring die 32 being too large, which causes the material layer in the pelletizing area to thicken, and the motor output pressure is too high, which leads to a decrease in pelletizing output or even stops operation; and avoid the gap between the pressure roller 16 and the ring die 32 being too small, which causes excessive friction between the pressure roller 16 and the ring die 32, thereby causing damage to parts and reducing their service life;
[0037] After the raw materials are basically processed, some of the raw materials will accumulate at the bottom. At this time, the hydraulic rod 26 can be started. The hydraulic rod 26 will push the mounting plate 25 to move. After the mounting plate 25 moves, it will cooperate with the cleaning plate 23. At this time, the top plate 22 is pressed into the inside of the first spring 21 by the connecting plate 14. The cleaning plate 23 contacts the surface of the mounting plate 25. At this time, after the connecting plate 14 rotates, the residual material at the bottom can be formed and processed, avoiding the accumulation of the bottom material, avoiding the increase of subsequent processing steps, improving work efficiency, and also avoiding the waste of materials.
[0038] After the raw materials are processed into biomass particles, the second drive motor 28 is started, and the second drive motor 28 starts to drive the fourth shaft 29 to rotate. The rotation of the fourth shaft 29 drives the first gear ring 31 to rotate. The rotation of the first gear ring 31 drives the cutting knife 33 to rotate along the outer surface of the ring die 32 to cut the extruded biomass particles, thereby completing the processing of the biomass particles. At the same time, the rotation of the cutting knife 33 can also push the cut biomass particles to be discharged, increase the discharge speed, and improve work efficiency.
