Microwave mixing heating and pressing device

Abstract

The invention discloses a hybrid microwave heating and pressurizing device which comprises a tank body, as well as a microwave generator, a fluid auxiliary temperature-regulating device, a vacuumizing device and a pressurizing device which are arranged on the tank body, the microwave generator is used for feeding microwaves into an inner cavity of the tank body and enabling a material in the tank body to generate self-heating, the fluid auxiliary temperature-regulating device is used for feeding an auxiliary temperature-regulating fluid into the inner cavity of the tank body so as to adjust the outside temperature of the material, and at least one of the microwave feed end, facing the inner cavity of the tank body, of the microwave generator, the fluid output end of the fluid auxiliary temperature-regulating device, the surface of the material or the inside of the material is provided with a temperature monitoring device for monitoring the temperature in real time. Microwaves are fed into the material in the inner cavity of the tank body by the microwave generator, and the temperature of the outer layer of the material is timely adjusted by the fluid auxiliary temperature-regulating device so as to prevent the problem that heat in the material is dissipated slowly and heat outside the material is dissipated quickly, in such a way, the temperature difference between inside and outside formed in the process of material curing is subducted, and the uniformity of a temperature field for material curing treatment in the tank body is ensured, thereby ensuring the quality of treated finished products.

Description

technical field [0001] The present invention relates to the field of hybrid heating and pressurizing equipment, in particular, to a microwave-hot air / steam mixed heating and pressurizing device for composite material curing, lamination of laminated glass components, rubber vulcanization and pressure steam curing production .

Problems solved by technology

[0007] The invention provides a microwave and auxiliary heat source microwave mixed heating and pressing device to solve the existing method of optimizing the temperature field of an autoclave using microwaves. When processing large-sized and thick composite material components, the internal heat dissipation of the components is slow and the external Fast heat dissipation will form an anti-external temperature difference in the component, which is high on the inside and low on the outside, and also cannot maintain the uniformity of the temperature field of the composite component curing process.
