Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1-4 The utility model provides a briquetting device for biomass pellet production: it includes a biomass briquetting machine body 1, the biomass briquetting machine body 1 is provided with a crushing mechanism 20, a feeding pipe 2 and a discharge plate 3, the feeding pipe 2 is fixedly connected to the top of the crushing mechanism 20, the top of the feeding pipe 2 is fixedly connected to the discharge hopper 4, the outer surface of the discharge hopper 4 is fixedly connected with an annular pipe 5, the annular pipe 5 is provided with a plurality of dust suction nozzles 6, the dust suction nozzles 6 pass through the discharge hopper 4 and extend to the inside, and the plurality of dust suction nozzles 6 are arranged in a circular array, the biomass briquetting machine body 1 is fixedly connected with a bracket 7, the bracket 7 is fixedly connected with a controller 13, the top of the bracket 7 is fixedly connected with a connecting frame 8 and a fan 9, the bottom of the connecting frame 8 is connected to the biomass briquetting machine body 1 through the discharge pipe 10, the interior of the connecting frame 8 is fixedly connected with a collecting hopper 19, the top of the connecting frame 8 is fixedly connected with a collecting box 11, the collecting box 11 is provided with a partition component, the interior of the collecting box 11 is fixed The filter plate 17 is connected to the collecting box 11, and the dust sucked into the collecting box 11 can be intercepted by the setting of the filter plate 17 to prevent a large amount of dust from entering the fan 9 and affecting its use. The two sides of the collecting box 11 are respectively connected to the annular tube 5 and the suction end of the fan 9. A slot 12 is provided on the collecting box 11, and the collecting box 11 is connected to the connecting frame 8 through the slot 12. Through the setting of the biomass briquetting machine body 1, the dust suction nozzle 6, the fan 9, the partition 15 and the filter plate 17 and other structures, the dust generated when the biomass particles are added and the dust generated when the biomass particles are crushed can be sucked and collected, avoiding the dust from spreading and polluting the working environment and being inhaled by the workers and affecting their health. At the same time, the collected dust can be transported to the inside of the biomass briquetting machine body 1 again, which can avoid the collected dust from being wasted and does not require the workers to clean and discharge the collected dust later, reducing the workload of the workers and thus improving the practicality of the device.

[0029] The partition assembly includes a rotating shaft 14, which is rotatably connected to the inside of the collecting box 11. The rotating shaft 14 rotates and passes through the filter plate 17. The outer surface of the rotating shaft 14 is fixedly connected with several partition plates 15 and several partition plates 2 16. The ends of partition plates 15 and 16 away from the rotating shaft 14 are movably abutted against the inner wall of the collecting box 11. The two sides of the filter plate 17 are movably abutted against one side of partition plate 15 and one side of partition plate 2 16 respectively. When the suction end of the starter of the fan 9 generates suction, the area below the rotating shaft 14 is blocked by the setting of partition plate 15 and partition plate 2 16 to reduce the influence of the suction, so that the dust driven by its rotation can be blown to the inside of the connecting frame 8 under the action of the wind force generated by its rotation. A stepper motor 18 is fixedly installed on one side of the collecting box 11, and the output end of the stepper motor 18 is fixedly connected to one end of the rotating shaft 14.

[0030] Working principle: During operation, biomass particles are added to the interior of the biomass briquetting machine body 1 through the lower hopper 4, and the crushing mechanism 20 crushes the biomass particles. At the same time, in the process of adding biomass particles, the controller 13 starts the stepper motor 18 and the fan 9. The stepper motor 18 starts to drive the rotating shaft 14 to rotate, and the rotating shaft 14 drives a number of partitions 15 and partitions 2 16 to rotate synchronously. After the fan 9 is started, its suction end generates suction. Under the cooperation of the collecting box 11 and the annular tube 5, the dust collection nozzle 6 generates suction, which can suck the dust generated when the biomass particles are added and the dust generated when the biomass briquetting machine body 1 crushes the biomass particles before briquetting. The dust is sucked into the annular tube 5 through the dust collection nozzle 6 and transported to the inside of the collecting box 11, and is intercepted by the filter plate 17 inside the collecting box 11.

[0031] At the same time, when the filter plate 17 intercepts the inhaled dust, the rotating partition 15 and partition 2 16 can prevent the filter plate 17 from being blocked by dust. At the same time, during its rotation, the intercepted dust can be moved to the bottom of the collection box 11, and when the other partitions 15 and partition 2 16 isolate the suction force of the fan 9, the dust is transported from the discharge chute to the inside of the collecting hopper 19 under the action of gravity and the wind force generated by the rotation of partition 15 and partition 2 16, and is transported again to the inside of the biomass briquetting machine body 1 through the discharge pipe 10, so that the collected dust is mixed with the crushed biomass particles and then briquetting is carried out.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
