Description

Technical Field

[0002] Biomass pellet fuel is essentially the direct combustion of biomass energy, representing the processing and utilization of biomass. Direct combustion methods can be categorized into four types: stove combustion, boiler combustion, waste combustion, and solid fuel combustion. Before processing, biomass fuel needs to be formed into pellets to meet the requirements of subsequent combustion operations.

[0003] In the prior art, patent publication number CN202321180960.1 discloses a biomass pellet fuel forming and extrusion equipment, including a box body. A forming component is fixedly installed on the left side of the bottom of the box body, a vibration component is installed on the right side of the bottom of the box body, a cleaning component is fixedly installed on the left side of the box body, a hydraulic cylinder is connected through the top left side of the box body, a pressure plate is fixedly installed at the bottom of the hydraulic cylinder, a mixing box is fixedly installed on the right side of the top of the box body, and heating components are fixedly installed on both the left and right sides of the mixing box.

[0004] The pellets produced by the above-mentioned equipment using extrusion and crushing have obvious problems.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figure 1-5 This embodiment provides a technical solution: a biomass pellet fuel forming device, including a forming chamber 1, a pellet forming mechanism 5 and a planetary gear drive mechanism 6;

[0026] Molding chamber 1: It is provided with a top cover 2 on its upper side, and a feeding hopper 3 is fixedly connected to the middle of the top cover 2. A base 4 is fixedly connected to the lower side of the molding chamber 1. A control switch 7 is provided on the front side of the base 4. The input end of the control switch 7 is electrically connected to an external power supply. A discharge hopper 8 is provided on the left side of the molding chamber 1.

[0027] Granulation Mechanism 5: It includes a slewing bearing 51, an abrasive box 52, a fixed grinding table 55, a dividing support plate 56, and a rotary grinding table 57. The slewing bearing 51 is fixedly connected to the upper inner side of the molding chamber 1 (the slewing bearing 51 uses a 797 / 1060g2 type slewing bearing). The abrasive box 52 is fixedly connected to the inner ring of the slewing bearing 51. The dividing support plate 56 is rotatably connected to the upper inner side of the abrasive box 52. The rotary grinding table 57 is rotatably connected to the middle of the dividing support plate 56. The fixed grinding table 55 is fixedly connected to the middle of the bottom wall of the molding chamber 1. The lower part of the feed hopper 3... The feed hopper 3 is fixedly connected to the upper surface of the fixed grinding table 55. The lower side of the feed hopper 3 has evenly distributed material leakage channels. The pellet forming mechanism 5 also includes irregular holes 53, inner grinding protrusions 54, and bottom spiral protrusions 58. The irregular holes 53 are evenly distributed on the inner arc surface of the abrasive box 52. Evenly distributed inner grinding protrusions 54 are fixedly connected to the inner arc surface of the abrasive box 52, the outer arc surface of the fixed grinding table 55, and the outer arc surfaces of the three rotating grinding tables 57. Evenly distributed bottom spiral protrusions 58 are provided on the lower side of the outer arc surfaces of the three rotating grinding tables 57. The pellet forming mechanism 5 also includes a material leakage avoidance opening 59 for material leakage. The clearance opening 59 is located in the middle of the partition support plate 56. The inner arc surface of the clearance opening 59 is rotatably connected to the lower side of the outer arc surface of the feed hopper 3. As the three rotating grinding tables 57 revolve around the fixed grinding table 55, they also rotate on their own axis. It is worth noting that the partition support plate 56 and the grinding box 52 rotate in opposite directions. At this time, external biomass raw materials can be poured into the grinding box 52 from the feed hopper 3 in sequence. At this time, the inner grinding protrusions 54 on the three rotating grinding tables 57 cooperate with the inner grinding protrusions 54 on the fixed grinding table 55 to grind the biomass raw materials into smaller particles. As the biomass raw material is continuously moved by the rotating grinding table 57, it will sink to the bottom of the forming chamber 1 when it is not ground properly. At this time, the bottom spiral protrusions 58 on the three rotating grinding tables 57 will also continuously flip up the unground biomass raw material, so that it can be fully ground by the inner grinding protrusions 54 until the biomass raw material is ground properly and meets the discharge conditions. After that, the diameter of the biomass particles is smaller than the diameter of the irregular hole 53, and it is moved to the left side of the forming chamber 1 by the rotating grinding table 57. Then the biomass particles are pushed out from the irregular hole 53 and discharged to the outside of the device through the discharge hopper 8.

[0028] Planetary gear drive mechanism 6: The planetary gear drive mechanism 6 is fixedly connected to the feed hopper 3 and the pellet forming mechanism 5 respectively. The planetary gear drive mechanism 6 includes an internal gear ring 61, an external gear ring 62, a driven gear 63, and a fixed gear 67. The internal gear ring 61 is fixedly connected to the upper side of the inner arc surface of the abrasive box 52. The external gear ring 62 is fixedly connected to the upper side of the outer arc surface of the abrasive box 52. The upper ends of the three rotary grinding tables 57 are respectively fixedly connected to drive gears 66. Each of the three drive gears 66 is meshed with an internal gear ring 61. A fixed gear 67 is fixedly sleeved in the middle of the inner arc surface of the feed hopper 3. Each of the three drive gears 66 is meshed with a fixed gear 67. The planetary gear drive mechanism 6 also includes a mounting housing 64. The motor 65 and drive gear 66 are fixedly connected to the right side of the top cover 2 via the mounting housing 64. The motor 65 is fixedly connected to the upper surface of the mounting housing 64. The output shaft of the motor 65 is fixedly connected to the drive gear 66, which meshes with the external gear ring 62. The input end of the motor 65 is electrically connected to the output end of the control switch 7. When the molding equipment is needed, the control switch 7 can be adjusted to make the motor 65 run. The output shaft of the motor 65 rotates, which drives the drive gear 66 to rotate, thereby driving the abrasive box 52 to rotate. In turn, the internal gear ring 61 drives the three driven gears 63 to rotate around the fixed gear 67. During this period, the partition support plate 56 rotates inside the abrasive box 52.

[0029] The working principle of the biomass pellet fuel molding equipment provided by this utility model is as follows: When the molding equipment is needed, the control switch 7 can be adjusted to start the motor 65. The output shaft of the motor 65 rotates, driving the drive gear 66 to rotate, which in turn drives the abrasive box 52 to rotate. This, in turn, drives the three driven gears 63 to rotate around the fixed gear 67 through the internal gear ring 61. During this period, the separating support plate 56 rotates inside the abrasive box 52. At this time, the three rotating grinding tables 57 also rotate on their own axis while revolving around the fixed grinding table 55. It is worth noting that the separating support plate 56 rotates in the opposite direction to the abrasive box 52. At this time, external biomass raw materials can be poured into the abrasive box 52 from the feed hopper 3. The inner grinding protrusions 54 on the three rotating grinding tables 57 work in conjunction with the inner grinding protrusions 54 on the fixed grinding table 55 to grind the biomass raw material into smaller particles. As the rotating grinding tables 57 continuously move the biomass raw material, it will sink to the bottom of the forming chamber 1 if it is not ground properly. At this time, the bottom spiral protrusions 58 on the three rotating grinding tables 57 will also continuously flip up the unground biomass raw material, so that it can be fully ground by the inner grinding protrusions 54 until the biomass raw material is ground properly and meets the discharge conditions. After that, the diameter of the biomass particles is smaller than the diameter of the irregular hole 53, and they are moved to the left side of the forming chamber 1 by the rotating grinding tables 57. Then the biomass particles are pushed out from the irregular hole 53 and discharged to the outside of the device through the discharge hopper 8.

[0030] It is worth noting that the motor 65 disclosed in the above embodiments can be freely configured according to the actual application scenario. It is recommended that the motor 65 be an RV series worm gear reducer. The control switch 7 is equipped with a control button corresponding to the motor 65 and used to control its switch.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
