Technical Field

[0001] The utility model relates to the technical field of impurity screening for biomass particle production, in particular to an impurity screening device for biomass particle production. Background Art

[0002] Biomass pellets are produced by cold-dense molding of crushed biomass straw, forestry waste and other raw materials using rollers and ring dies at room temperature. The density of the raw materials is generally 0.1-0.13t / m³, and the density of the molded pellets is 1.1-1.3t / m³, which is convenient for storage and transportation and greatly improves the combustion performance of biomass. However, when producing and processing biomass pellets, the materials need to be screened. However, the current screening device has a relatively simple structure and cannot transmit the materials after long-term shaking screening, resulting in incomplete screening. Therefore, an impurity screening device for biomass pellet production is proposed. Utility Model Content

When in use, the first baffle is slidably installed inside the screening box, and then the material is poured into the screening box through the feed port, and the vibration motor at the bottom of the screening plate is started. The vibration motor will drive the screening plate to vibrate, thereby screening impurities in the material. At the same time, the first baffle will block the material to prevent it from flowing out.
