Design And Research Of Combination Balance System For The Conical Pulp Plate Of Pulping Refiner

Pulp plate is one of the important components of the refiner.The quality of pulp plate affects the pulping quality of pulp and the service life of papermaking equipment.The problem of installation and balance of pulp plate is particularly important.If the installation of pulp plate is not balanced,it will lead to severe consequences such as severe vibration of the papermaking equipment,reduced service life,and reduced production efficiency of the papermaking enterprise.This article takes a conical pulp plate as an example.Through interviews with a large number of companies,the combinatorial optimization method of conical pulp plate often uses dynamic balance detection.The dynamic balance detection method has problems such as high labor intensity,high cost,and low efficiency.In order to solve these problems,this paper uses a three-point measurement method to measure the mass center of mass and an intelligent optimization algorithm to design a combined balance system.The specific work is as follows:First of all,according to the structural characteristics of the conical pulp plate,how to obtain the mass and center of mass of the conical pulp plate,the static centroid measurement method,mechanical gravity positioning method,dynamic centroid measurement method,and multi-fulcrum measurement method are proposed.Through the feasibility analysis of the accuracy and complexity of the measurement method of the mass centroid of the conical pulp plate,it was finally determined that the three-point measurement method of the multi-point measurement method can quickly measure the mass and centroid of the conical pulp plate at one time.The accuracy and reliability of the three-point measurement method are proved by actual example verification.Secondly,according to the structure characteristics and the shape of the combined conical grinding plate,the structure of the combined balance system of the conical grinding plate is designed by CATIA and solid works.In this paper,the finite element analysis of the fixture structure of the conical grinding plate combined balance system of the pulp plate is carried out,and the stress-strain diagram of the fixture structure of the conical grinding plate is obtained.Based on the lightweight design idea,the topological optimization design and modal analysis of the conical grinding plate fixture structure are carried out.The results show that the mass of the optimized conical grinding plate is46.85% less than that of the previous one,and the stress,displacement and modal effect ofthe optimized conical grinding plate support plate are good.Finally,according to the mass and center of mass data measured by the conical grinding plate combination balance system of pulp plate,the optimization problem and algorithm of conical pulp plate combination are studied and analyzed.The improved adaptive genetic algorithm is used for combination optimization,and the corresponding software operation interface is designed according to visual studio 2010 c #.The experiment shows that the designed conical grinding plate combination balance system of pulp refiner meets the technical requirements.The designed system not only effectively solves the shortcomings of the dynamic balance correction equipment,but also extends the service life of the cone-shaped grinder and equipment,and improves the economic benefits of the cone-shaped grinder manufacturers.The research of this paper also provides a reference for the research of the balance system in other fields.
