Combined with the actual choice of the production process and product solutions, also carried out relevant material balance, energy balance, economic accounting. The total annual production of long glass fiber polypropylene PICKLES design tasks for 5000 tons, according to the formula calculated the annual demand of 3,358 tons of polypropylene over glass fiber reinforced body's annual demand of more than 1250 tons. This design uses two long glass fiber reinforced polypropylene sheet production lines, working 300 days a year, 16 hours a day production schedule.
Conducted a workshop layout design based on 5,000 tons of long fiber reinforced polypropylene sheet plant process design. In this design, the use of rectangular plant workshop plant. Plant size (length × width × height) 36m × 70m × 10m. Rectangular plant to facilitate the general layout for the whole plant, land conservation, convenient device arranged to facilitate arrangements for transportation and entrance, there are more walls to provide natural lighting and ventilation design to use, and designed to leave space to facilitate the expansion of production.
This design is also fully consider the issue of staff safety and environmental protection. In the production process, requiring strict compliance with the rules of production staff, good-toxic protective measures, and regularly participate in relevant training for information.
This design according to the design task book assigned task, successfully enhanced polypropylene sheet workshop process design of long fiber. In the whole process of design, I have a general understanding of the production of long fiber reinforced polypropylene sheet flow. And on the basis of professional knowledge, combined with their own experience in the cognitive practice, flexible application, to engage in the future related to production management work to lay a certain foundation.
This design is guided by high-Nan, made many valuable comments and positive suggestions to help me improve the design quality. And classmates to explore together also designed to bring a lot of help. Here, I express my sincere thanks.
The knowledge about the long glass fiber reinforced polypropylene sheet plant process design is so amplitude, but mine are limited . Cordially obsecrating teachers to make a comment on the design’s mistakes.
