Projecção de uma máquina para produção de briquetes a partir da serradura de madeira

Abstract

The proposed work deals with the design of a machine for the production of briquettes from wood sawdust, aiming to replace traditional fuels such as firewood and fossil fuels, with an ecological fuel, with high calorific value and low cost. As it results from the densification of solid biomass residues that can generally be found in some industries and in the environment in the form of waste. The methodology adopted consists of a bibliographical research based on consultation of books, manuals, scientific articles and website pages with materials related to the production of briquettes, wood waste, elements and machine designs. Initially, the properties of wood sawdust were analyzed, including its humidity, density and calorific value, in order to guarantee the viability of compaction. Next, the main briquetting methods were studied, with an emphasis on mechanical compaction. The designed machine is a press composed of a compression system that uses a hydraulic jack, punch block and cylindrical matrix to compact the sawdust at high pressure, forming high-density cylindrical briquettes. In sizing the machine and designing the prototype, mechanical principles, mathematical formulas, a calculating machine, Autodesk inventor and AutoCAD were used. The project also included productivity analysis and cost analysis, and it was concluded that there could be a return on the entire investment after two months and one wee
