Description

Technical Field

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

[0002] In industrial boilers, residential heating stoves, and other equipment, biomass pellets can replace traditional fuels such as coal and oil, providing heat energy for factories, schools, hospitals, and homes. Some small biomass pellet heating stoves are easy to operate, have high combustion efficiency, and can provide a warm and comfortable environment for families. Biomass pellets can also be used as fuel in biomass power plants. By burning the pellets to generate steam, which drives a steam turbine to generate electricity, this not only reduces dependence on traditional fossil fuels but also effectively utilizes waste biomass resources, achieving resource recycling.

[0003] However, existing technologies still have many shortcomings in practical applications. For example, biomass pellets usually need to be extruded to form specific shapes and densities. If the extrusion process is inconvenient or impossible, the pellets may not achieve the expected molding effect. At the same time, biomass pellet briquettes have specific requirements for shape and size in many application scenarios. If they are inconvenient to cut and shape, the briquettes may be too large or irregular in shape, making them unusable. Alternatively, they may not burn completely during combustion, leading to energy waste and increased pollutant emissions.

[0004] To address the aforementioned problems, the inventors have proposed a biomass pellet briquetting machine forming device to solve these issues. Utility Model Content

[0008] With the above technical solution, the second motor is started, and its output end drives the third rotating shaft fixedly connected to it to rotate. The drive gear fixedly sleeved on the outer surface of the third rotating shaft rotates accordingly. The drive gear meshes with the gear ring. The rotation of the drive gear will drive the gear ring to rotate. When the gear ring rotates, the scraper will make a circular motion. The scraper will cut the extruded material into a suitable length, which can effectively cut and shape biomass pellets into blocks.

[0009] As a preferred technical solution of this application, a funnel is fixedly connected to the top surface of the box.

[0012] Through the above technical solution, the fixing box can protect the first bevel gear and the second bevel gear.

[0013] As a preferred technical solution of this application, a plurality of stirring rollers are fixedly connected to the outer surface of the second rotating shaft, and the size of the stirring rollers decreases sequentially from top to bottom.

[0014] Through the above technical solution, the stirring roller stirs and initially mixes the biomass raw materials entering from the funnel, making the raw materials more evenly distributed.

[0015] As a preferred technical solution of this application, the bottom end of the auger is rotatably connected to the lower inner wall of the discharge port.

[0016] With the above technical solutions, the auger can rotate more stably.

[0017] As a preferred technical solution of this application, the outer surface of the scraper is in contact with the discharge port.

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.

[0030] Example: Figure 1-5 As shown, this utility model provides a biomass pellet briquetting machine forming device, including a box body 1, a funnel 4 fixedly connected to the top surface of the box body 1, a bottom plate 2 fixedly connected to the lower part of the box body 1, a cutting device 3 fixedly connected to the lower part of the box body 1, and an extrusion device 5 fixedly connected inside the box body 1.

[0031] The extrusion device 5 includes a fixed box 501. The two sides of the fixed box 501 are fixedly connected to the inner walls of the housing 1. A first rotating shaft 502 is rotatably connected between the two inner walls of the fixed box 501. A first motor 503 is fixedly connected to the upper part of the housing 1. The output end of the first motor 503 passes through the housing 1 and extends into the fixed box 501, where it is fixedly connected to the first rotating shaft 502. A first bevel gear 504 is fixedly sleeved on the outer surface of the first rotating shaft 502. A second bevel gear 505 is meshed with the outer surface of the first bevel gear 504. The first bevel gear 504 and the second bevel gear 505 are connected in a meshing manner. 5 is located inside the fixed box 501. The bottom surface of the second bevel gear 505 is fixedly connected to the second rotating shaft 506. The outer surface of the second rotating shaft 506 is movably connected to the fixed box 501. Multiple stirring rollers 507 are fixedly connected to the outer surface of the second rotating shaft 506. The size of the stirring rollers 507 decreases from top to bottom. The bottom end of the second rotating shaft 506 is fixedly connected to the auger 508. The end of the box 1 is fixedly connected to the housing 509. The bottom surface of the housing 509 has multiple discharge ports 510 arranged in a ring array. The bottom end of the auger 508 is rotatably connected to the lower inner wall of the discharge port 510.

[0032] During the rotation of the second rotating shaft 506, the stirring roller 507 stirs and initially mixes the biomass raw materials entering the fixed box 501 from the funnel 4, making the raw materials more evenly distributed. As the second rotating shaft 506 rotates, the auger 508 also starts to rotate. The rotation of the auger 508 will squeeze the stirred biomass raw materials downward and transport them into the shell 509. Under the squeezing action of the auger 508, the raw materials are squeezed out from the discharge port 510.

[0033] The cutting device 3 includes symmetrically distributed support plates 31. Both sides of one end of the support plate 31 are fixedly connected to fixed plates 32. The top surface of the fixed plates 32 is rotatably connected to a third rotating shaft 33. The bottom surface of one of the support plates 31 is fixedly connected to a connecting plate 35. The top surface of the connecting plate 35 is fixedly connected to a second motor 36. The output end of the second motor 36 extends into one of the fixed plates 32 and is fixedly connected to the third rotating shaft 33. The outer surface of the third rotating shaft 33 is fixedly sleeved with a drive gear 37. The outer surface of the drive gear 37 is meshed with a gear ring 38. A scraper 39 is fixedly connected to one inner wall of the gear ring 38. The outer surface of the scraper 39 is in contact with the discharge port 510.

[0034] When the toothed ring 38 rotates, the scraper 39 moves in a circular motion, cutting the extruded material into appropriate lengths.

[0035] The working principle of the biomass pellet briquetting machine forming device according to an embodiment of this application is as follows: After the first motor 503 is started, its output end drives the first rotating shaft 502 to rotate. The first bevel gear 504 fixedly sleeved on the first rotating shaft 502 rotates accordingly. The rotation of the first bevel gear 504 drives the second bevel gear 505 to rotate. The second rotating shaft 506 rotates together with the second bevel gear 505. During the rotation of the second rotating shaft 506, the stirring roller 507 stirs and initially mixes the biomass raw materials entering from the funnel 4, making the raw materials more evenly distributed. As the second rotating shaft 506 rotates, the auger 508 also starts to rotate. The rotation of the auger 508 will squeeze the stirred biomass raw materials downward and convey them into the shell 509. Under the squeezing action of the auger 508, the raw materials are squeezed out from the discharge port 510, thereby achieving the purpose of effectively squeezing the biomass pellet raw materials.

[0036] When the second motor 36 is started, its output end drives the third rotating shaft 33, which is fixedly connected to it, to rotate. The drive gear 37, which is fixedly sleeved on the outer surface of the third rotating shaft 33, rotates accordingly. The drive gear 37 meshes with the gear ring 38. The rotation of the drive gear 37 will drive the gear ring 38 to rotate. When the gear ring 38 rotates, the scraper 39 will make a circular motion. The scraper 39 will cut the extruded material into a suitable length, thereby achieving the purpose of effectively cutting and shaping biomass pellets into blocks.
