Description

Technical Field

[0001] The utility model relates to the technical field of biomass particles, in particular to a conveying device for biomass particle briquetting. Background Art

[0002] Biomass pellets are made by cold-forming and compacting pulverized biomass straw, forestry waste, and other raw materials using rollers and ring dies at room temperature. The raw material density is generally 0.1-0.13 t / m³, and the pellet density after forming is 1.1-1.3 t / m³, making it easy to store and transport, and significantly improving the combustion performance of the biomass.

[0003] The utility model patent of patent application announcement number CN215401039U discloses a biomass pellet conveying device, including a quadrilateral with corners protruding outward, the corners of the quadrilateral are rotatably connected to rotating rollers, and a conveyor belt is supported and rotated between four groups of rotating rollers, and the middle part of the quadrilateral is hinged with a tensioning tube extending downward, the tensioning arm is rotatably connected to the tensioning wheel, and a spring is installed between the tensioning arm and the quadrilateral. The upper front and rear sides of the conveyor belt are provided with baffles fixed to the quadrilateral, and the middle and upper part of the quadrilateral is provided with an intentional frame. The utility model is suitable for conveying biomass pellets. Through the first vibration motor, the powder and grains in the pellets can be layered, so that the powder is located at the bottom and the particles are located at the top, preparing for subsequent powder separation, which is beneficial to improving the effect of powder separation: through the vibrating filtering mechanism, the powder and particles can be further separated, thereby achieving full separation of the particles.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that it cannot absorb and filter the biomass pellet debris during the biomass pellet conveying process. When the biomass pellets leave the conveyor belt, a large amount of dust will be generated, polluting the surrounding environment and reducing the environmental friendliness of the conveying device. Therefore, in order to solve this problem, we have proposed a conveying device for biomass pellet briquetting. Utility Model Content
