Biomass fuel preparation pretreatment device

Abstract

The invention discloses a biomass fuel preparation pretreatment device. The biomass fuel preparation pretreatment device comprises a towing bracket. A micro diesel engine, a generator, a storage battery and a pretreatment box are arranged on the top of the towing bracket. A flywheel belt disc of the micro diesel engine is connected with a connecting belt pulley of the generator in a transmission mode through a first belt. A smashing chamber, a drying channel and a discharging chamber are formed inside the pretreatment box. A smashing device is arranged between the two opposite sides of the inner wall of the smashing chamber. Electric heating blocks are arranged on the front side and the rear side of the drying channel, and a material conveying device is arranged inside the drying channel.The invention relates to the technical field of biomass fuel. The biomass fuel preparation pretreatment device solves the problems that an existing raw material pretreatment device which adopts a smashing machine to smash and process raw materials only has a smashing effect and cannot remove soil or gravel and water in raw materials, specifically, the soil or the gravel and the water do not generate the heat, stacking storage is not facilitated, and the combustion efficiency of the biomass fuel is reduced.

Description

technical field [0001] The invention relates to the technical field of biomass fuel, in particular to a pretreatment device for preparing biomass fuel. Background technique [0002] Biomass fuel: refers to the burning of biomass materials as fuel. Generally, it is 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, directly Burning 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, extrusion Pressing, drying and other processes, made into various shapes (such as block, granular, etc.), a new type of clean fuel that can be directly burned. At present, the production and processing of ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a biomass fuel preparation pretreatment device, which solves the problem that the existing raw material pretreatment device that uses a pulverizer to pulverize the raw material has only a pulverization function and cannot treat the raw material in the raw material. The soil or sand and water that do not produce heat are removed, which is not conducive to stacking and storage, and reduces the fuel efficiency of biomass fuels
