Intelligent decision-making and design system and method for grinding disc of disc mill for pulping and papermaking

Abstract

The invention discloses an intelligent decision-making and design system and method for a grinding disc of a disc mill for pulping and papermaking. The system comprises a human-computer interaction interface, a demand index evaluation module, a quality function expansion module, a problem recognition module, a mathematical model library module, a design scheme evaluation module, a system connection module and an abrasive disc computer aided design platform module. A database, a knowledge base and an abrasive disc design parameter machine learning sub-module supported by the knowledge base arearranged below the mathematical model library module. the method comprises: after a demand is received, organizing the demand into a demand index; determining the importance degree of the user demandelements according to the demand index evaluation model; respectively converting requirements into slurry characteristic requirements and abrasive disc design requirements; defining a grinding problemthrough grinding piece design requirements, determining a grinding mode and a grinding tooth type, generating grinding piece design main parameters by applying a grinding piece prediction model, quantitatively evaluating the generated grinding piece scheme, inputting grinding piece scheme ideal solution parameters into a grinding piece CAD system, and generating a grinding piece three-dimensionalmodel. The research and development period of the abrasive disc is shortened and the research and development cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of disc refiners in pulp and papermaking, and in particular relates to an intelligent decision-making and design system and method for disc refiner discs used in pulp and papermaking, which are used for disc refiner discs of low, medium and high consistency Design proposal generation. Background technique [0002] As the core equipment in the pulping process, the disc refiner plays a vital role in the pulp quality. As the core component (heart) of the disc grinder, the grinding disc is particularly important. [0003] Determining the best solution for grinding discs according to customer needs is a very complicated task. At present, the procedure of this work is as follows: firstly, the user puts forward the paper production requirements and provides the performance parameters of the fiber raw materials. The plan is handed over to a special production department or enterprise for the production of the pro...

Problems solved by technology

This work procedure has high production costs, wastes resources, and has a long R&D cycle, which weakens the competitiveness of enterprises. The program is too subjective, and the valuable knowledge and experience of R&D and use of grinding discs are highly concentrated on industry experts, which cannot benefit enterprises and other demanders.
