Abstract

The invention discloses a pretreatment device for solid biomass fuels, and belongs to the technical field of agricultural machinery. The technical scheme is that: the pretreatment device comprises a motor (2) and a smashing device (4) arranged on a stand (1), and a cutter disc (10) and a smashing device (11) arranged in the cutting and smashing device (4); and the pretreatment device is characterized in that: cutters (12) with different combinations are distributed on ring holes of the cutter disc (10) along the periphery, and form a closed cutting and smashing chamber together with a side knife (15) and a bottom knife (16); and blades (13) and hammers (14) are peripherally arranged on the smashing device (11) to form a smashing chamber and a discharge chamber. The pretreatment device for the solid biomass fuels can cut and smash biomass materials, such as crop stalks, forestry remainders and the like by adjusting the combinations of the smashing cutters, effectively solves the smashing problem of various raw materials before the formation, and can provide a technical support for the formation of the solid biomass fuels.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and is a biomass solid molding fuel pretreatment device, specifically crushing and mixing biomass raw materials such as crop stalks and forestry residues before molding to meet molding requirements. Background technique [0002] my country is rich in crop straw resources and forest resources. According to statistics, the annual output of crops is about 600 million tons per year, equivalent to about 300 million tons of standard coal, and the forestry residue is about 150 million tons. Biomass solid briquette fuel technology is a high-tech technology that dries and pulverizes the original dispersed biomass without a certain shape into various briquettes with a certain shape and high density under the action of a certain temperature and pressure. It is 6-8 times smaller, with a density of 1.0-1.4t / m3. The energy density is equivalent to that of medium-quality bituminous coal. When use...
