Drying control method, system, equipment, simulation optimization and application of microwave drying

Abstract

The invention belongs to the technical field of microwave drying, and discloses a drying control method, system, equipment, simulation optimization and application of microwave drying. The sensing module composed of eight sensors performs operation monitoring and feedback in time to ensure the safety of the truck. Buffering, room entry and delivery; the dehumidifier inside the dehumidification module dehumidifies the goods to be dried; according to the set requirements, when the number of trucks in the drying room meets the requirements, the isolation on both sides of the drying area will be closed The door dries the material; the cooling module cools the goods by controlling the fan. The PLC-based touch control system of the present invention is connected with the entire process modules, and all the modules are divided into manual and automatic modes to ensure that the entire operation process is carried out in an orderly manner. The COMSOL Multiphysics software is used to conduct dynamic numerical simulations on the temperature and moisture content during the drying process of materials, and optimize the drying process through simulation to improve drying efficiency.

Description

technical field [0001] The invention belongs to the technical field of microwave drying, and in particular relates to a drying control method, system, equipment, simulation optimization and application of microwave drying. Background technique [0002] At present: water-based paint coating is divided into two types: machine spraying and manual spraying: machine spraying is now more mature in the market, including reciprocating machines, five-axis machines, spray machines, vacuum spraying machines, etc. The investment cost of this equipment is relatively large, and There must be a certain amount of production support; there is another kind of manual spraying. The traditional spray gun plus diaphragm pump spraying does not need to be modified, which saves costs, but the fluency of the gun is poor. The traditional spray gun plus the oil supply pressure barrel uses pressure to send the paint out of the gun, reducing the air pressure by an appropriate amount and reducing the reb...

Problems solved by technology

[0006] (1) With the current rise of the domestic water-based paint coating industry, the traditional drying method is no longer sufficient to meet the domestic market demand and environmental protection requirements

[0007] (2) At present, domestic high-efficiency and environment-friendly microwave drying equipment is successfully used in the furniture water-based paint industry. Microwave drying has a rigorous and efficient industrial process and control method, and how to improve drying efficiency as much as possible

The microwave drying of its water-based paint lacks sufficient theoretical guidance, and the drying process needs to be optimized
