Abstract

The invention provides a vacuum microwave drying recycling treater of a high temperature-resistant communication cable insulation process. The vacuum microwave drying recycling treater is characterized by comprising a microwave dryer (1), a coil heat exchanger (2), a vacuum pump (5), an auxiliary recovery storage tank (3), an infrared temperature detector (22) and a feedback and control system (23), wherein the microwave dryer (1) comprises a microwave emission device (6), and a cable transmitting and microwave heating cavity; the coil heat exchanger (2) is connected with the vacuum pump (5) by use of a vacuum pipe (19); the microwave emission device (6) is composed of a microwave emitter (7), a waveguide tube (8) and a resonant cavity (9). The vacuum microwave drying recycling treater has the advantages of high drying efficiency, and evener and more thorough volatilization of auxiliaries, and more dispersive and evener pores formed in an insulating layer, and therefore, the low dielectric constant and the good quality of the insulating layer are guaranteed; in addition, the auxiliaries can be recycled after vacuum condensation and reflux, and therefore, the production cost can be reduced and the economic benefit can be improved.
