Improved Design of Screen Mechanism in Steelmaking Plant
To solve the problem of clogging and difficult cleaning of screens in steel mills,an ejector pin structure was added to the lower screen.This paper analyzes the transmission structure and motion structure of the screen,and theoretical preparations are made for the design parameters of the screen rotation device and the motion trajectory of the screen plate.A motor is constructed to cooperate with a transmission structure to drive the screen,and the linkage screen and ejector pin are used to loosen the coal material.We calculate the motion trajectory and mode of the screen and thimble,establish a mathematical model of the motor and linkage screw mechanism,and find out their matching mode.SolidWorks software is utilized to accurately construct each group of parts of the screen mechanism into a three-dimensional structure and complete the virtual assembly.The screen mechanism has the advantages of simple structure,convenient operation and labor saving,which is suitable for large-scale material filtration and can improve industrial production efficiency.
