Technical Field

[0001] The utility model relates to the technical field of biomass fuel pretreatment, in particular to a dust purifier for biomass fuel production. Background Technique

[0002] Biomass fuel refers to using biomass materials as fuel, generally mainly agricultural and forestry waste, such as straw, sawdust, bagasse, rice bran, etc. It is mainly different from fossil fuels. The application of biomass fuel is actually mainly biomass briquette fuel. Taking agricultural and forestry waste as raw materials, through processes such as crushing, mixing, extrusion, and drying, it is made into various shapes, such as block-shaped, granular, etc., and can be directly burned as a new type of clean fuel. When processing biomass fuel, it is necessary to purify the dust in the biomass fuel to maintain the processing purity of the biomass fuel.

[0003] The existing dust filters for biomass fuel processing generally vibrate the screen reciprocally, put the biomass fuel on the top of the screen for vibration, so that the dust is filtered out from the screen. Since the vibration amplitude is relatively small, some dust mixed inside the biomass fuel is difficult to be completely cleaned out, and the working efficiency of filtering dust is low, and it is not convenient to quickly filter out the dust. Therefore, a dust purifier for biomass fuel production is needed to solve the above problems. Content of the Utility Model
