中文摘要:基于生物质固化成型领域活塞冲压式成型机能耗低、生产率低和模辊式成型机生产率高、能耗高的特点,提出一种新型对辊式成型方式,并设计和制造了样机。该成型机压辊圆周上均布了一系列柱塞,运行过程中压辊柱塞与环模模孔相互啮合,避免了成型孔之外的物料受到压辊的挤压与摩擦。为测试该成型机的性能,进行了正交试验研究,结果表明,该成型机的较优成型参数为:含水率15%,成型模具长径比5.25,主轴转速47.25r/min。以木屑为原料,在较优成型参数的条件下进行了成型机性能指标的测试,结果表明,该成型机生产的成型颗粒直径为10mm,成型颗粒密度为1.15g/cm3,机械耐久性为96.28%,生产率为75kg/h,能耗为56kW·h/t,成型率为95%,工作噪声为79dB,各项指标均达到设计要求,实现了连续稳定生产。

Abstract:The characteristics of both the piston stamping forming machine and the die roller briquetting machine were combined. The piston stamping forming machine has low energy consumption and low productivity while the die roller briquetting machine has high productivity and high energy consumption, a new kind of roller briquetting method was put forward, and the prototype was designed and manufactured. Compared with other same type briquetting machine, a series of plungers distributed on the roller mesh into the ring die holes in the briquetting process, which could avoid the loss of energy consumption and the serious wear problem in the process of biomass materials squeezed outside ring die holes. In order to test the property of this briquetting machine, the orthogonal experiment was preceded. Results showed that the optimal processing parameters for the roll briquetting machine with plungers: the length to diameter ratio of forming mould is 525, the spindle speed is 47.25r/min, and the moisture content of raw material is 15%. Under the optimal processing parameters, sawdust was used as raw material for the briquetting test. Experimental results showed that the diameter of the forming particle is 10mm, the density of forming particle is 1.15g/cm3, the mechanical durability is 96.28%, the productivity of the briquetting machine is 75kg/h, the energy consumption is 56kW·h/t, the forming rate is 95%, and the working noise is 79dB. All the indexes meet the design requirements, and realize continuous and stable production. This has a certain role in promoting the development of biomass curing technology, and the briquetting method put forward in this paper provides the reference for the biomass densification technology and the development of the same kind equipment.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
