Drying device for biomass fuel

Abstract

The invention discloses a drying device for a biomass fuel. The drying device for the biomass fuel comprises a bottom plate, a motor, a drying box and a roller, wherein the drying box is arranged on the bottom plate; the roller transversally penetrates into the drying box; the two ends of the roller are located outside the drying box separately; a charge port and a discharge port are formed in thetwo ends of the roller separately; a carrier roll assembly supporting a body of the roller and arranged on the bottom plate is arranged below the two ends of the roller separately; a gear ring is arranged on the outer wall of one end of the roller; the motor is arranged on the bottom plate, and a main shaft of the motor is coaxially connected with a gear engaged with the gear ring on the outer wall of the roller; a spiral guide sheet is arranged on the inner wall of the roller; and the spiral guide direction of the spiral guide sheet is the discharge port direction of the roller. The drying device for the biomass fuel is simple and novel in structure, low in cost, convenient to use, and high in drying efficiency.

Description

technical field [0001] The invention relates to the technical field of biomass fuel processing, in particular to a biomass fuel drying device. Background technique [0002] Biomass fuel: refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry wastes (such as straw, sawdust, bagasse, rice bran, etc.). The main difference is from fossil fuels. In the current national policy and environmental protection standards, direct combustion of biomass is a highly polluting fuel, which is only used in large stoves in rural areas and is not allowed to be used in cities. The application of biomass fuel is actually mainly biomass briquette fuel, which uses agricultural and forestry waste as raw materials, and is made into various shapes (such as lumps, granules, etc.) through crushing, mixing, extrusion, drying and other processes. A new type of clean fuel that can be directly burned. [0003] The existing biomass fuel drying device is easy to break...
