Material processing apparatus using quasi-traveling microwave to conduct heat treatment

A material processing apparatus, comprising:

• a primary waveguide tube, having a front opening and a rear opening;
• a microwave blocking plate, being connected to the primary waveguide tube for shielding the rear opening, and having at least one material exporting hole;
• a secondary waveguide tube consisting of a first segment and a second segment, wherein the first segment has a first opening correspondingly connected to a waveguide tube of a microwave source, the second segment having a second opening for being correspondingly assembled with the front opening of the primary waveguide tube, a bending angle existing between the second segment and the first segment, and the first segment is provided with at least one material importing hole thereon that is coaxial to the at least one material exporting hole;
• and
• at least one microwave absorbing member made of a microwave absorbing material, being disposed of in the primary waveguide tube, and having at least one hollow cavity;
• wherein by using a driver device, at least one thread-type article being fed into the secondary waveguide tube via the at least one material importing hole, subsequently moving into at least one hollow cavity, and eventually leaving the primary waveguide tube via the at least one material exporting hole of the microwave blocking plate;
• wherein the microwave source supplies a microwave into the second waveguide tube and the primary waveguide tube, such that the microwave travels in the second waveguide tube and the primary waveguide tube along a wavefront so as to become a quasi-traveling microwave;
• wherein in case of moving in the second waveguide tube and/or the primary waveguide tube, a first part of the thread-type article and the microwave absorbing member being both heated because of receiving the quasi-traveling microwave, and a second part of the thread-type article being heated by inner walls of the hollow cavity.
