Device for producing high-heat-value biomass fuel from agricultural and forestry waste

Abstract

The invention discloses a device for producing high-heat-value biomass fuel from agricultural and forestry waste. The device comprises a temperature sensor, a drying drum motor and a rack, wherein a motor is arranged at the lower part in the rack; a driving wheel is arranged at the left end of the motor; a screening bin is arranged above the motor; a round roller is arranged in the screening bin;a filter screen is arranged below the round roller; a smashing bin is arranged above the rack; the temperature sensor is mounted at the upper part in a drying drum, and the drying drum motor is mounted below the drying drum. By means of a solenoid valve, automatic feeding can be realized, feeding quantity can be controlled, and automation is realized; a drying device adopts a drum structure, so that the biomass fuel rolls in the device and is heated more uniformly, the dried biomass fuel is conveyed out under reverse rotation of the motor, operation is simple and convenient, and the device issafe and practical.

Description

technical field [0001] The invention belongs to the technical field of agricultural and forestry processing, and in particular relates to a device for producing high calorific value biomass fuel by using agricultural and forestry waste. 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 policies and environmental protection standards, direct combustion Biomass is a high-pollution 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 undergoes crushing, mixing, and extrusion , drying and other processes, made of various shapes (such as block, granular, etc.), a new type of clean fuel tha...
