年产30万只塑料储油箱车间工艺设计(2)
As for the choice of the recipe design and shape methods, in order to improve the tensile strength, rigidity and chemical stability of the products, join the sticks together to the raw materials to improve their performance. And by comparing extrusion blow molding and injection blow molding the pros and cons and select extrusion blow-molded to the design of the overall process. In order to ensure that products of the wall thickness uniformity and to prevent continuous extruder transition when unprocessed because of their self-esteem reaching into the large or the products cooling excessive, and ultimately taking the intermittent extrusion blow molding method.
In the total technical process, referenced and compared to the correlation books, I draw up the total flow charts and add the concrete explanations. According to the plastic machine design standard, we can take the flow refinement to explain on craft pretreatment, craft formation. And select the related type equipment by correlation description and technical parameter arrangement.
In the gas transfer network design, to transports the amount of wind, the wind speed and the transportation density carries on the computation, guarantees its craft transportation the integrity and smooth, considered the pressure loses, and finally choose the XGB turbine wheel type air pump.
In the material balance, determined first the operating time, then through the conservation relations, the product specification and the cycle period determination extruding machine and mixer productivity and the corresponding quantity, simultaneously displays in each process the product output, the loss and the waste product quantity, in order to finally determine raw material the amount of use.
In the energy balance, through the energy balance figure lists which extruder molding machine and mold part of the energy related calculations to determine the usage of the cooling water and the chilled water. And then further determine the usage of raw material, and conclude that the power consumption for the design and auxiliary equipment.
In the workshop non-technological design, this design has also fully considered the question of personal security and the environmental protection, and determines personnel arrangement of production organization. In the production process, it requests workers should obey the working instruction strictly. To the environmental protection aspect, also control the waste water and the noise emissions strictly.
In the economic accounting, I make the product cost estimate by the estimate the expense of project equipment to this design, preparing for full for the product going on the market localization.
In the final of the design is the layout of the workshop, which introduces the workshop composition and design principles simply. Through the power supply, the storage material, the stacking between the equipment such as the design and production of emissions from the plant, we can determine the size of the workshop.
