Abstract

This invention discloses a rotating, visual microwave heating device and method. A viewing window is provided on the side wall of the furnace shell, and tempered glass is installed on the viewing window. A radiation-proof metal mesh is installed between the two layers of tempered glass, connecting the radiation-proof metal mesh to the side wall of the furnace shell. A wide-angle infrared thermal imager and a microwave heating device are installed on the top of the furnace shell. A radiation-proof metal cylinder is nested inside the furnace shell. An opening is provided on the side wall of the radiation-proof metal cylinder, and a large-aperture metal mesh is installed at the opening. The top of the radiation-proof metal cylinder is open, and a loading disk is arranged inside the radiation-proof metal cylinder. A ring-shaped internal metal gear is arranged at the bottom of the radiation-proof metal cylinder. This invention provides a cylindrical, rotating microwave heating and separation device that is visually appealing, easy to measure temperature, provides symmetrical environmental electromagnetic fields, has good microwave electromagnetic radiation protection, and strong heat preservation performance, realizing visualization in the microwave heating and crushing concrete aggregate extraction experiment.
