Structural design of LW450F-N horizontal scroll decanter centrifuge
Major: process equipment and control engineering
Student: Teacher:
Abstract:Horizontal scroll decanter centrifuge is a centrifuge machine which is widely used in processing industrial separation of slurry. It has automation, a continuous operation, wide application range, compact structure, large single capacity of production and other characteristics. Now it also has been widely used in chemical, petrochemical industry ,oil refining, light industry, medicine, food, textile, metallurgy, coal, mineral, marine, environmental protection, military and other fields of solid-liquid separation. The topic for the task is to design a horizontal scroll decanter centrifuge which drum diameter is 450mm for methanol purification. Firstly, sketch out the meaning of the task and the research status of horizontal scroll decanter centrifuge in China and other countries in the World. Then design and calculate the main parts of the centrifuge, like the bowl and the helical conveyor, also study the production capacity and the power. For other assist parts, such as differential, electrical machine, Bearings and so on, select the model; plish transmission design and sealing equipment. Moreover check the strength of the big end. Finally, the situation of current domestic and foreign centrifuge research and development is summed up and expected.
Key Words: horizontal scroll decanter; structural design; transmission design; strength check
