南京林业大学 本科毕业设计 题 目：年产40万吨牛皮卡纸生产车间的设计 学 院：轻工科学与工程学院 专 业：制浆造纸装备与控制 学 号： 学生姓名： 指导教师： 职 称：讲师 二O一二年五月十五日 摘要）考虑到以上因素，本设计中用抄纸。 通过此次设计，让我对造纸工艺和机械设计方面都有很大的收获。毕业设计不仅是对前面所学知识的一种检验，而且也是对自己能力的一种提高。通过这次毕业设计使我明白了自己原来知识还比较欠缺。自己要学习的东西还太多Abstract Packaging board in the national economy and peoples life plays an increasingly important role in. Over the years, our mechanism for paper and paperboard production volume in place has and steel position be roughly the same, and the national economy is closely related to. Packaging paperboard growth and improvement of peoples living standard is inseparable, it is foreign trade exit wind vane. This design is to complete an annual output of 400000tons (120g / m2) kraft paper workshop of preliminary design. Firstly, design verification, to determine the process parameters, the parameters of water balance calculation, and then based on the result of the calculation with the factory and production practice for equipment selection, the results were plotted according to the selection of workshop layout, and presents the process flow diagram. The process, using three overlapping of papermaking. The surface layer, the core layer, the bottom of the quantitative ratio of 1:1:2. Taking into account all these factors, the design of the use of wood as the surface layer25%,25% of the waste paper pulp as the core layer and the50% waste paper pulp as the bottom copy kraft paperboard.After calculation through the entire process of fiber volume and fiber volume out error is0.0020kg, is a balance. Entering in the whole process of slurry and slurry error for 10.0020kg, within, but also balance. Through this design, let me on the papermaking process and mechanical design has great harvest. Graduation design is not only on the front of the knowledge of a kind of test, but also to their ability of a raise. Through this graduation design makes me understand their knowledge is relatively deficient. Their own to learn too much. Key word
