Biomass fuel drying device

Abstract

The invention discloses a biomass fuel drying device. The biomass fuel drying device comprises a drying barrel, barrel doors and supporting seats, wherein the drying barrel is arranged in a barrel-shaped structure horizontally placed; the circular barrel doors are rotationally connected to both ends of the drying barrel through spring hinges; the peripheral curved surface of the drying barrel is fixedly welded to the inner rings of two sets of outer bearings arranged in parallel as well as the inner wall of one set of hollow gears, and the hollow gear is arranged on one sides of the two sets of outer bearings; the two sets of supporting seats arranged in parallel are arranged below the drying barrel, and the two sets of supporting seats are fixedly connected with each other through a connecting rod; the top end of each of the supporting seats is fixedly welded to the peripheral curved surface of the corresponding outer bearing; and a rotary motor is fixedly welded to the top end of oneset of supporting seats, a solid gear is connected to an output shaft of the rotary motor through a screw rod, and the solid gear is arranged on one side of the hollow gear. The biomass fuel drying device disclosed by the invention is thorough in drying, high in drying speed and high in drying efficiency, so that the cost is greatly saved.

Description

technical field [0001] The invention belongs to the technical field of drying, and in particular relates 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 waste (such as straw, sawdust, bagasse, rice bran, etc.), which is mainly different 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. However, during the preparation process, the dryness of the raw mater...

AI Technical Summary

Problems solved by technology

However, during the preparation process, the dryness of the raw materials is generally not very high, but the traditional drying equipment is used to dry directly, and the inside of the raw materials cannot be completely dried. Thorough and complete drying will consume a lot of energy and the cost is relatively high.
