Optimum Design of Multidischarge Outlet Biomass Briquetting Machine

Abstract

A high-efficiency biomass material was designed according to the densification mechanism of biomass. This machine improved the efficiency by recombining the feeding stage, prepressing stage, compaction stage, pressure-holding stage, and pushing stage of the compression process, so that part of the working stages was carried out simultaneously. To further improve efficiency and rationally allocate power at each stage, in this paper, we established a mathematical model for the machine. We use the nonlinear programming in Matlab (2016b) to solve the minimum value of the model, making the machine work time the shortest.

Structural Model of Straw Briquetting Machine with Vertical Ring Die and Optimization of Briquetting Performance

“…Then, the conveying belt will transport the briquette to the sieve for screening, and it is bagged and sealed after cooling. The two extrusion zones in the chamber are symmetrically distributed relative to the center, and the significant pressure gradient along the rotation direction of the ring die and the press roller causes material reflow [24]. According to the different degree of extrusion of the material, the compression room is divided into three zones, which are the feeding zone, the deformation extrusion zone, and the extrusion forming area (Figure 2) [25].…”
