[0002] At present, biomass pellets are cold-formed and compacted by using rollers and ring dies at room temperature to crush biomass straw, forestry waste and other raw materials, which is convenient for storage and transportation and greatly improves the combustion performance of biomass. Generally, when the material is extruded to form particles, the rotating roller is usually pressed against the inner wall of the granulating chamber and rotated to extrude the material in the granulating chamber so that the material passes through the holes on the granulating chamber and is reversely extruded to form particles. Since the material is basically transported to the inside of the granulating chamber through the conveying device during extrusion, and the material is relatively dense inside the granulating chamber, it is easy for the dense material to be partly gathered into agglomerates when the rotating roller rotates, which can easily lead to stagnation or partial blockage of the agglomerated material during extrusion, affecting the extrusion efficiency of the material.

[0014] The present invention has the following beneficial effects: 1. In the present invention, when the motor drives the cross plate to rotate through the fan shaft, the rotation of the cross plate will drive the extrusion cylinder and the gear shaft to rotate synchronously. When the extrusion cylinder rotates, it will extrude the material inside the granulation ring. Then, when the cross plate drives the gear shaft to rotate, the rotation of the gear shaft will rotate in the staggered gear plates inside the C-shaped ring. At this time, the gear shaft will be affected by the staggered gear plates in the staggered gear plates in the C-shaped ring and reciprocate. When the gear shaft reciprocates, the rotation of the gear shaft will drive the cone plate to rotate through the intermediate ring and the connecting plate. Then, when the cone plate rotates, the rotation of the cone plate will drive the raised ring to rotate synchronously through the connecting plate 2. Then, when the raised ring rotates, the rotation of the raised ring will slide up and down in the Z-groove on the intermediate cylinder along the guidance of the Z-groove. When the raised ring reciprocates up and down When the conical plate slides, the sliding of the raised ring will push the conical plate to swing back and forth on the fixed ring through the connecting plate 2. When the conical plate rotates and swings back and forth, the swing of the conical plate will slap the material inside the extrusion barrel back and forth. The slapping of the material by the reciprocating swing of the conical plate can reduce the aggregation of materials during the rotation and extrusion of multiple extrusion barrels, which helps to improve the fluidity of the material, so that the material is pushed to the granulation ring and the extrusion barrel for granulation during the extrusion process. Subsequently, when the multiple conical plates rotate back and forth with the gear shaft, the rotation of the conical plate will reciprocate and knead the material inside the extrusion barrel, so that the existing material clumps are further dispersed, making the material more uniform, which is conducive to the smooth extrusion of the extrusion barrel and reduces the risk of blockage due to material stagnation.

[0015] 2. In the present invention, when the conical plate rotates and reciprocates, the swing of the conical plate will intermittently squeeze the elastic plate through the flexible inner wall inside the extrusion cylinder. When the elastic plate is squeezed, it will push the bottom of the elastic frame to move upward. Since the top of the elastic frame is fixed to the top inner wall of the hollow groove, when the bottom of the elastic frame is pushed by the elastic plate, the elastic frame will move upward under the push of the elastic plate. When the bottom end of the elastic frame moves upward, the elastic frame will form an outward bulging deformation. When the elastic frame is deformed, the deformation of the elastic frame will push the flexible inner wall of the extrusion cylinder to fit with the conical plate. At the same time, when the elastic frame is deformed, When deformed, the deformation of the elastic skeleton will drive the spring block to shake, and then when the conical plate rotates, the rotation of the conical plate can make the spring block shake back and forth inside the elastic skeleton to impact the inner wall of the extrusion barrel. The reciprocating bulge deformation of the elastic skeleton and the reciprocating impact of the spring block can reduce the adhesion of materials to the conical plate and the inner wall of the extrusion barrel when the conical plate beats and kneads the materials to be extruded, reduce the impact of the conical plate on the kneading and beating of the materials due to the adhesion of the materials inside the extrusion barrel, reduce the adhesion of the materials inside the extrusion barrel, and improve the dispersion efficiency of the conical plate on the material agglomerates, thereby improving the looseness of the materials before extrusion and the extrusion efficiency of the materials.

[0016] 3. In the present invention, when the motor drives the fan shaft to rotate, the rotation of the fan shaft will squeeze the insertion rod on the strong spring rod through the annular serrated groove on the surface of the fan shaft. After being squeezed, the insertion rod will move downward to the top ring through the strong spring rod. When the strong spring rod moves downward, it will compress the strong spring inside the strong spring rod. Then, when the fan shaft continues to rotate, the fan shaft will drive the annular serrated groove to rotate synchronously. When the insertion rod on the strong spring rod rotates to the straight path of the annular serrated groove, the strong spring inside the strong spring rod will suddenly bounce the top ring upward. When the top ring moves downward, it will push the telescopic ring to expand outward through the middle plate. At the same time, when the telescopic ring expands, it will drive the elastic sleeve to expand synchronously. Then, when the strong spring rod drives the top ring to bounce up, the bounce of the top ring will be pushed through the elastic sleeve. The material falling on the elastic sleeve is pushed toward the inner wall edge of the extrusion barrel and the granulation ring. At this time, the elastic sleeve drives the material to bounce, which not only helps to evenly distribute the material inside the granulation ring, but also when the top ring drives the elastic sleeve to bounce, the elastic sleeve will drive the elastic shaking plate to shake inside the elastic sleeve and impact the elastic sleeve, further increasing the looseness of the material when it falls. At the same time, the elastic sleeve's bouncing of the material can also increase the contact opportunity between the material and the inner wall of the granulation ring and enter the inside of the extrusion barrel through the square groove on the extrusion barrel, promoting better processing of the material. At the same time, it can also reduce the situation where the material is far away from the edge of the granulation ring, causing insufficient extrusion of the material by the extrusion barrel, which helps to ensure that the material has more consistent quality during extrusion, thereby improving the overall quality of the particles and the uniformity of the particles.

[0017] 4. In the present invention, when the top ring moves downward, the movement of the top ring will drive the rotating frame to move downward synchronously, and when the rotating frame moves downward, the downward movement of the rotating frame will drive the telescopic frame to move downward synchronously. When the telescopic frame moves downward, the flexible ring at the bottom of the telescopic frame will be above the extrusion cylinder. Then, when the telescopic frame moves downward, the downward movement of the telescopic frame will drive the rotating frame 2 and the spherical rod on the rotating frame 2 to squeeze the limit rod. After being squeezed, the limit rod will rotate on the top of the cross plate. At the same time, when the limit rod rotates, the rotation of the limit rod will drive the rotating frame 2 to deflect synchronously through the spherical rod. Then, when the fan shaft drives the limit rod to rotate, the rotation of the limit rod will The spherical rod drives the rotating frame 2 to rotate synchronously. The rotating frame 2 will rotate in a circular wave motion state. When the rotating frame 2 rotates in a wave state, the rotation of the rotating frame 2 will periodically squeeze the spring shaft. After the spring shaft is squeezed, it will drive the flexible ring to slide down on the inner wall of the granulation ring. When the spring shaft pushes the flexible ring to slide downward, the sliding of the flexible ring will push and scrape the squeezed and adhered materials on the granulation ring, and scrape off the materials adhered to the inner wall of the granulation ring to prevent the materials from gradually accumulating on the inner wall, thereby reducing the adhesion of the materials and making the quality of the materials entering the extrusion link more stable. This is conducive to producing particles with regular shapes and uniform density, and improving the overall quality of the particles.

Then, when the cone plate 401 rotates, the rotation of the cone plate 401 drives the raised ring 405 to rotate synchronously through the connecting plate 2 404. Then, when the raised ring 405 rotates, the raised ring 405 slides up and down in the Z-shaped groove on the intermediate cylinder 305 along the guidance of the Z-shaped groove. When the raised ring 405 slides reciprocatingly up and down, the sliding of the raised ring 405 will push the conical plate 401 to swing reciprocatingly on the fixed ring 303 through the connecting plate 404. When the conical plate 401 rotates and swings reciprocatingly, the swing of the conical plate 401 will reciprocately beat the material inside the extrusion cylinder 302. The reciprocating swing of the conical plate 401 on the material can reduce the aggregation of materials during the rotation and extrusion of multiple extrusion cylinders 302, which helps to improve the fluidity of the material, so that the material is pushed to the granulation ring 204 and the extrusion cylinder 302 for granulation during the extrusion process. Subsequently, when the multiple conical plates 401 rotate reciprocatingly with the gear shaft 406, the rotation of the conical plate 401 will reciprocate and knead the material inside the extrusion cylinder 302, so that the existing material clumps are further dispersed, making the material more uniform, which is conducive to the smooth extrusion of the extrusion cylinder 302 and reduces the risk of blockage due to material stagnation.

[0035] When the conical plate 401 rotates and reciprocates, the swing of the conical plate 401 will intermittently squeeze the elastic plate 501 through the flexible inner wall inside the extrusion cylinder 302. When the elastic plate 501 is squeezed, it will push the bottom of the elastic skeleton 502 to move upward. Since the top of the elastic skeleton 502 is fixed to the top inner wall of the hollow groove 304, when the bottom of the elastic skeleton 502 is pushed by the elastic plate 501, the elastic skeleton 502 will move upward under the push of the elastic plate 501. When the bottom end of the elastic skeleton 502 moves upward, the elastic skeleton 502 will form an outward bulging deformation. When the elastic skeleton 502 is deformed, the deformation of the elastic skeleton 502 will push the flexible inner wall of the extrusion cylinder 302 to fit with the conical plate 401. At the same time, the elastic skeleton 502 When deformation occurs, the deformation of the elastic skeleton 502 will drive the spring block 503 to shake, and then when the conical plate 401 rotates, the rotation of the conical plate 401 can make the spring block 503 shake back and forth inside the elastic skeleton 502 to impact the inner wall of the extrusion cylinder 302. The reciprocating ridge deformation of the elastic skeleton 502 and the reciprocating impact of the spring block 503 can reduce the adhesion of materials to the conical plate 401 and the inner wall of the extrusion cylinder 302 when the conical plate 401 beats and kneads the materials to be extruded, reduce the impact of the conical plate 401 on the kneading and beating of the materials due to the adhesion of the materials inside the extrusion cylinder 302, reduce the adhesion of the materials inside the extrusion cylinder 302, and improve the dispersion efficiency of the conical plate 401 on the material clumps, thereby improving the looseness of the materials before extrusion and the extrusion efficiency of the materials.

[0036] When the motor 201 drives the fan shaft 202 to rotate, the rotation of the fan shaft 202 will squeeze the insertion rod on the strong spring rod 605 through the annular serrated groove on the surface of the fan shaft 202. After being squeezed, the insertion rod will move downward to the top ring 601 through the strong spring rod 605. The strong spring rod 605 will compress the strong spring inside the strong spring rod 605 when moving downward. Then, when the fan shaft 202 continues to rotate, the fan shaft 202 will drive the annular serrated groove to rotate synchronously. When the insertion rod on the strong spring rod 605 rotates to the straight path of the annular serrated groove, the strong spring inside the strong spring rod 605 will suddenly bounce the top ring 601 upward. When the top ring 601 moves downward, it will push the telescopic ring 603 to expand outward through the middle plate. At the same time, when the telescopic ring 603 expands, it will drive the elastic sleeve 602 to expand synchronously. Then, when the strong spring rod 605 drives the top ring 601 to bounce up, the bounce of the top ring 601 will be The sleeve 602 pushes the material falling on the elastic sleeve 602 toward the inside of the extrusion cylinder 302 and the inner wall edge of the granulation ring 204. At this time, the elastic sleeve 602 drives the material to bounce up, which not only helps to evenly distribute the material inside the granulation ring 204, but also when the top ring 601 drives the elastic sleeve 602 to bounce up, the bounce of the elastic sleeve 602 will drive the elastic shaking plate 604 to shake inside the elastic sleeve 602 and impact the elastic sleeve 602, further improving the looseness of the material when falling. At the same time, the bounce of the material by the elastic sleeve 602 can also increase the contact opportunity between the material and the inner wall of the granulation ring 204 and enter the inside of the extrusion cylinder 302 through the square groove on the extrusion cylinder 302, thereby promoting better processing of the material. At the same time, it can also reduce the situation where the material is far away from the edge of the granulation ring 204, causing the extrusion cylinder 302 to extrude the material insufficiently, which helps to ensure that the material has more consistent quality during extrusion, thereby improving the overall quality of the particles and the uniformity of the particles.

[0037] When the top ring 601 moves downward, the movement of the top ring 601 will drive the rotating frame 701 to move downward synchronously. When the rotating frame 701 moves downward, the downward movement of the rotating frame 701 will drive the telescopic frame 703 to move downward synchronously. When the telescopic frame 703 moves downward, the flexible ring 705 at the bottom of the telescopic frame 703 will be above the extrusion cylinder 302. Then, when the telescopic frame 703 moves downward, the downward movement of the telescopic frame 703 will drive the rotating frame 2 702 and the spherical rod on the rotating frame 2 702 to squeeze the limiting rod 306. After being squeezed, the limiting rod 306 will rotate on the top of the cross plate 301. At the same time, when the limiting rod 306 rotates, the rotation of the limiting rod 306 will drive the rotating frame 2 702 to deflect synchronously through the spherical rod, and then the fan shaft 202 drives the limiting rod 306 to rotate. When the rotation of the limit rod 306 is performed, the rotation of the limit rod 306 will drive the rotating frame 2 702 to rotate synchronously through the spherical rod. The rotating frame 2 702 will rotate in a circular wave motion state. When the rotating frame 2 702 rotates in a wave state, the rotation of the rotating frame 2 702 will periodically squeeze the spring shaft 704. After the spring shaft 704 is squeezed, it will drive the flexible ring 705 to slide downward on the inner wall of the granulation ring 204. When the spring shaft 704 pushes the flexible ring 705 to slide downward, the sliding of the flexible ring 705 will push and scrape the squeezed and adhered materials on the granulation ring 204, and scrape off the materials adhered to the inner wall of the granulation ring 204 to prevent the materials from gradually accumulating on the inner wall, thereby reducing the adhesion of the materials and making the quality of the materials entering the extrusion link more stable. This is conducive to producing particles with regular shapes and uniform density, and improving the overall quality of the particles.
