Technical Field

[0001] The utility model relates to the technical field of biomass energy particle forming equipment, in particular to a biomass energy particle forming device with adaptive forming and extrusion. Background Art

[0002] Biomass energy pellets are made by cold-dense molding of crushed biomass, straw, forestry waste and other raw materials using a compression and mixing molding die at room temperature. After compression molding, the volume of biomass is greatly reduced, making it easier to transport, store and use, solving the problem of large-scale utilization of biomass. Therefore, this technology and equipment are very suitable for industries such as biomass power generation and clean energy transformation of industrial boilers.

[0003] With current technology, the raw materials are usually crushed and dried, and then the crushed raw materials are pressed into particles by mechanical devices. The forming mechanism generally consists of a pressure working area composed of a press roller and a forming die. The crushed biomass raw materials enter the working area through the discharge port and are extruded and formed before being discharged. The press roller is fixed on the power disc, which is fixed on the power spindle and connected to the motor through a transmission mechanism.

[0004] At present, the molding equipment has the following problems: due to the continuous wear of the pressure roller and the molding die, the pressure between them cannot be continuously maintained in the optimal range, and the molding efficiency is low; a small amount of impurities such as hard wood, concrete, and iron nails are mixed in the raw materials, causing the pressure roller and the molding die to be crushed and scratched. For this reason, we provide an adaptive molding extrusion biomass energy particle molding device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 - Figure 4 As shown, the utility model provides a technical solution: an adaptive forming and extruding biomass energy particle forming device, comprising an equipment body 1, a feed hopper 2 is installed inside the equipment body 1, and the inside of the equipment body 1 can be injected with material through the feed hopper 2. A discharge port is opened inside the equipment body 1 to facilitate the discharge of processed materials.

[0026] A support plate 3 is installed inside the equipment body 1, and the support plate 3 can separate the inside of the equipment body 1. A forming mold 4 is installed outside the support plate 3. The forming mold 4 is a cylindrical metal mold. A plurality of discharge holes 17 are opened inside the forming mold 4. The discharge holes 17 are arranged in a circular array inside the forming mold 4. The material inside the forming mold 4 can be discharged through the discharge holes 17 after processing.

[0027] The support plate 3 is internally rotatably connected to a power shaft 5, a control motor 14 is installed on the outside of the equipment body 1, an output end of the control motor 14 is fixedly connected to a bevel gear 15, the outside of the bevel gear 15 teeth are meshed with a bevel gear 2 16, an outer surface of the power shaft 5 is fixedly connected to the inside of the bevel gear 2 16, the control motor 14 can drive the bevel gear 15 to rotate, and can further drive the bevel gear 2 16 to rotate and control the power shaft 5 to rotate.

[0028] A power disk 6 is installed on the outside of the power shaft 5, and the power disk 6 can be controlled to rotate through the power shaft 5. A pressure roller 7 is installed on the outside of the power disk 6, and the pressure roller 7 can be driven to rotate by the power disk 6. The gap between the pressure roller 7 and the forming mold 4 can generate pressure on the material during processing, which facilitates the processing of the material.

[0029] An eccentric shaft 8 is installed inside the pressure roller 7, and a connecting frame 18 is fixedly connected to the outer surface of the power shaft 5. The outer surface of the eccentric shaft 8 is rotatably connected to the inside of the connecting frame 18. The eccentric shaft 8 and the power shaft 5 are connected by the connecting frame 18, so that the pressure roller 7 can be limited and fixed. An adjusting plate 20 is installed outside the power disk 6. The adjusting plate 20 is connected and fixed to the connecting frame 18 by fixing bolts and a mounting plate. Two groups of adjusting plates 20 are provided and arranged symmetrically. A certain installation gap is left between the power disk 6 and the pressure roller 7. The gap between the power disk 6 and the pressure roller 7 can be adjusted by the adjusting disk to eliminate the eccentricity between the power disk 6 and the molding die 4 due to wear or installation.

[0030] The outer surface of the eccentric shaft 8 is slidably connected with a rotating handle 9. The rotating handle 9 is provided with two groups and is arranged diagonally. The outer surface of the eccentric shaft 8 is fixedly connected with a spline 19. The outer surface of the spline 19 is meshed with the inside of the rotating handle 9. The eccentric shaft 8 can be fixed by the meshing of the rotating handle 9 and the spline 19. When the eccentric shaft 8 is rotated, the rotating handle 9 needs to be removed first, and then the eccentric shaft 8 can be rotated.

[0031] The inside of the rotating handle 9 is slidably connected with a screw rod 10, and the outer surface of the screw rod 10 is slidably connected with the inside of the power disk 6. The two groups of rotating handles 9 are connected through the screw rod 10. The outside of the screw rod 10 is covered with a butterfly spring 11. The outer surface of the butterfly spring 11 contacts the outer surface of the rotating handle 9, and the outer surface of the butterfly spring 11 contacts the outer surface of the adjusting nut 12. Multi-layer butterfly springs 11 are installed on the screw rod 10, which can provide a more stable torque for the rotating handle 9 within a certain range of elastic deformation, thereby ensuring that the pressure between the pressing roller 7 and the forming die 4 is in the optimal range.

[0032] The outer surface of the screw rod 10 is threadedly connected with an adjusting nut 12 and a locking nut 13, respectively. The outer surface of the adjusting nut 12 is slidably connected to the outer surface of the rotating handle 9, and the outer surface of the adjusting nut 12 is slidably connected to the outer surface of the locking nut 13. The pressure between the pressure roller 7 and the forming mold 4 can be readjusted to the optimal range through the adjusting nut 12. After tightening the locking nut 13, the stability of the connection between the screw rod 10 and the adjusting nut 12 can be guaranteed.

[0033] Further expanding, each screw rod 10 can also apply a continuous and smooth torque to only one rotating handle 9. As long as this continuous torque is provided by a spring, a spring, a gas spring, or an oil cylinder or an air cylinder with a pressure storage device, it will fall within the scope of protection of this patent.

[0034] Further expanding, the pressure of each pressing roller 7 on the forming die 4 can also be provided directly through an elastic element. When a small amount of impurities with higher hardness such as miscellaneous wood, concrete, nails, etc. are mixed into the raw materials, the elastic element will automatically retreat to protect the pressing roller 7 and the forming die 4 from being crushed. The elastic element can be a spring, a spring, a gas spring, or an oil cylinder or an air cylinder with a pressure storage device, etc., all of which will fall within the scope of protection of this patent.

[0035] Working principle: A pair of rotating handles 9 are connected together by a screw rod 10, and the extrusion pressure between the press roller 7 and the forming die 4 is adjusted by adjusting the nut 12. The butterfly spring 11 is within the effective compression stroke, through the screw rod 10, the adjusting nut 12, and the rotating handle 9, to ensure that the extrusion pressure between the press roller 7 and the forming die 4 is maintained within the optimal range. When the wear between the press roller 7 and the forming die 4 is too large, and the butterfly spring 11 is deformed and released to the point where the extrusion pressure between the press roller 7 and the forming die 4 cannot be maintained within the optimal range, the rotating handle 9 can be removed, rotated outward a few teeth and then reinstalled, and the pressure between the press roller 7 and the forming die 4 can be re-adjusted to the optimal range by adjusting the nut 12, and the locking nut 13 is tightened, and an adjustment procedure is completed.
