Title Special Dust-extraction Device For Spraying Production Line of Wheel Hub
Abstract
The graduation design is special dust-extraction device for spraying production line of wheel hub.This device is designed to realize the function of recycling the excess painting powder in the production line,and purify the air in spraying workshop as well.The device is mainly composed of filter,inverse blowing system and the fan .The detailed design of the inverse blowing system is introduced in this paper , then the suitable filter and fan is selected referring the measured data in the powder injection workshop,and the simple PLC control for inverse blowing system and fan is designed.The material of filer and design specification is chosen by analyzing the dust contraction and requirements of dust-extraction accuracy.The inverse blowing system is composed of solenoid valve, nozzle, pump, etc.The solenoid valve and distance of inverse blowing is designed,and the efficiency of the inverse blowing system is optimized.Then, the fan in terms of the parameters of the inverse blowing system and filter is selected,and the installation and maintenance of the fan and other relevant information is given in the paper.Finally, the PLC control program for the solenoid valve and fan is designed.
