Abstract
Microwave irradiator 12 is attached to a furnace main body of a heating furnace 11 having microwave permeability. A running passage for passing a fiber member F which is the object to be heated is formed inside the heating furnace 11. A first tubular member 13 made of a first microwave heat-generating material absorbing microwave energy and generating heat is rotatably disposed around the running passage. A second tubular member made of a second microwave heat-generating material absorbing microwave energy and generating heat is disposed in the first tubular member 13. The fiber member F is heated and calcined while running the fiber member F containing carbon in the running passage of the second tubular member 14.
Claims10
A microwave heating apparatus comprising:
- a heating furnace in which a microwave irradiator is attached to a furnace main body having microwave permeability;
- a running passage formed inside the heating furnace for passing a fiber member which is an object to be heated;
- a first tubular member which is made of a first microwave heat-generating material for absorbing microwave energy and generating heat in the heating furnace, the first tubular member being rotatably disposed around the running passage;
- and
- a second tubular member which is made of a second microwave heat-generating material for absorbing microwave energy and generating heat in the first tubular member, the running passage being formed at a center portion of the second tubular member,
- wherein the fiber member is heated and calcined while running the fiber member in the running passage of the second tubular member, and
- wherein the first tubular member has formed therein through holes or through slits extending in a radial direction, the through holes or through slits allowing a microwave to pass therethrough to be directly irradiated to the fiber member in the running passage of the second tubular member.
