In the total process, reference related documents, to determine the total production process and raw material pretreatment process, and to be specific. Reference plastic machinery design standards, refining processes required for each step of the technical parameters of the equipment, as well as models, etc
In the selection of equipment, combined with the design of the production process, the selection of appropriate equipment for each process, and gives the relevant parameters of each device, such as models, power and size, etc.. The parameters can provide a strong basis for energy balance, economic accounting and workshop layout.
In the material balance, the material balance is calculated based on the mass conservation law. First of all, to determine the basis of the calculation of material balance, including the number of days of production, production time and the loss rate of each link, etc.. Secondly, the process flow diagram is given can calculate the consumption of raw materials and product yield, in each stage of the production process of consumption and component and so on. Finally, the raw material consumption table is given, which can be carried out for economic calculation.
Through the material balance, determine the corresponding number of working hours, the main equipment. At the same time, the output and loss of each process and the amount of waste products are listed, which can provide reference for the design of raw materials.
In the energy balance. Firstly, the flow chart of energy balance is given, and the necessary of the energy transfer process is briefly introduced. Secondly, the extrusion blow molding system and mold parts for energy calculation, in order to seek the amount of cooling water and chilled water. In the second section of this chapter, according to the order of the production process, the power calculation of the equipment used in the production process is carried out, and the total power loss is given. At the end of this chapter, we give a comprehensive table of energy loss. The table can provide the basis for economic accounting.
In the energy conversion of the content, through the extrusion blow molding machine and mold part of the calculation of energy balance, the amount of cooling water and chilled water, and further determine the specific amount. At the same time, the design of the power consumption.
In the workshop of non process design, the number of personnel and the position of the workshop were briefly arranged. At the same time, also consider the workshop safety and environmental protection issues, including heating, ventilation and water treatment etc..
In raw material consumption table, energy consumption table and comprehensive equipment table is based on the premise, considering the other factors, estimated the cost of the design, the estimation result can be as the design rationality evaluation conditions.
Design the content of the last workshop layout, simply introduces the requirements and principles of the workshop layout. Combined with the equipment selection and the production process of the workshop layout, the design of the specific workshop layout made a brief description. The results are presented in the form of shop floor plan.
