Efficient Vibration Cleaning Sieve Vibration System Design And Research

Efficient cleaning sieve vibration in the mechanization of modern society more and more widely used,especially widely used in food processing,mining, metallurgy,construction and other industries. With the development of modern economy,the demand of the market,the existing high efficiency vibration cleaning sieve in production efficiency,service life and cleaning efficiency and energy conservation, environmental protection and so on higher requirements are put forward. And the vibration of the currently used cleaning sieve connecting spring and sieve body exist in the structure of bearing reinforcement strength is weak, the feed end and discharge end at the same time,the screen body design defects such as the strength of the side panel is relatively weak, the existing such problems not only directly affect the working performance and service life of the vibrating screen,can also affect the progress of the enterprise and even delay the rapid development of social economy.Therefore, studying the dynamics of vibration cleaning sieve system and its structure,eliminating the stress concentration of vibrating screen structure, and reducing stress and avoid structure resonance,for improving the vibration cleaning sieve working reliability,prolong the service life of the vibrating screen is of great significance.This paper introduces the research and development status of vibration cleaning sieve,combined TQLZ100 × 200 vibration cleaning sieve of its structural characteristics,vibration cleaning sieve systematic analysis of the vibration characteristics of not only this vibrating cleaning sieve of the original model and dynamic characteristics were analyzed, and by changing the spring-loaded position in the vertical direction,and thus vibration characteristics and dynamic characteristics of the new model have been studied for vibrating screen structure design, improvement and optimization direction.1. Based on the principle of energy, the use of Equation Lengrand established TQLZ100200 vibration cleaning sieve movement differential equations,numerical methods for solving differential equations were analyzed and deduced relevant theoretical parameters for subsequent theoretical simulation basis for comparison.2. On the basis of three-dimensional modeling,combined with the kinematic analysissoftware ADAMS,for TQLZ100200 vibration cleaning sieve original model was simulated kinematics,come to the movement of the vibration cleaning sieve,but also for all directions of vibration cleaning sieve trajectories are analyzed. By analyzing the change in spring stiffness parameters,spring bearing position in the vertical direction,the new model was simulated kinematics,vibration cleaning sieve structure optimization direction.3. The use of finite element analysis software ANSYS Workbench,respectively,of the original model and new model modal analysis,harmonic response analysis,the vibration cleaning sieve first 10 modal stress contours,and the spring support in the shaft finite element analysis results for each model a straight direction at different locations were analyzed and compared,the results of the analysis to verify the stiffness and strength of the structure are able to meet the practical requirements,but also for structural design improvements provided.4. Combination SO Analyzer data acquisition and analysis system for field vibration test was carried out on the clear TQLZ vibration sieve, understand the actual vibration of vibratory cleaning sieve the acceleration pulse and the spectrum characteristic, and the results of the analysis and comparison of the results of the finite element analysis simulation of the fourth chapter, the results of finite element simulation analysis for validation.
