Abstract

Disclosures of the present invention describe a coaxial microwave rotary applicator for material processing, mainly comprising: a waveguide unit, a microwave generator connected to one end of the waveguide unit, a bearing unit, a chamber, a rotary shaft, a driver unit, a sampling unit. The bearing unit is connected to the waveguide unit through a non-rotary ring, and the chamber is connected to a rotary ring of the bearing unit, and the microwave generator is configured for supplying a microwave to the chamber. By such arrangements, it is able to uniformly heat a specific material disposed in the chamber by driving the chamber to rotate. It is worth noting that, a user is allowed to clearly observe the processing progress via the sampling unit during the heating process of the specific material.

First claim

What is claimed is:

1. A coaxial microwave rotary applicator for material processing, comprising:
a microwave generator;
a waveguide tube, being connected to the microwave generator;
an adapter tube, being connected to the waveguide tube by a side thereof, and having a first opening and a second opening;
a bearing, being connected to the first opening of the adapter tube;
a lid, being connected to the second opening of the adapter tube, and comprising a plurality of wire holes and an axis hole, wherein the bearing is disposed in the axis hole;
a chamber being connected to a rotary ring of the bearing by a top opening thereof, such that the microwave generator is allowed to supply a microwave into the chamber through the waveguide tube and the adapter tube;
a rotary shaft, wherein a first end of the rotary shaft sequentially passes through the axis hole and the bearing located in the axis hole, the adapter tube, and the bearing, so as to connect the chamber;
a motor, being connected to a second end of the rotary shaft; and
a hollow cylindrical member, being connected to the bearing by a top opening thereof, and accommodating the chamber therein.

2. The coaxial microwave rotary applicator of claim 1 , wherein a material feeding opening, a first sample withdrawing opening and a first material discharging opening are formed on one side of the hollow cylindrical member, and a second sample withdrawing opening and a second material discharging opening are formed on one side of the chamber.

3. The coaxial microwave rotary applicator of claim 1 , further comprising:
a transparent sheet, being disposed in the bearing, so as to be positioned over the top opening of the chamber; wherein the transparent sheet is provided with a through hole thereon, and the rotary shaft passing through the through hole so as to connect the chamber.

4. The coaxial microwave rotary applicator of claim 1 , wherein a mesh plate comprising a plurality of vents is connected to a bottom opening of the chamber, and a cooling device having a cooling fan is connected to a bottom opening of the hollow cylindrical member.

5. The coaxial microwave rotary applicator of claim 1 , further comprising:
a plurality of isolation members, being disposed in the chamber for separating an internal of the chamber into a plurality of processing spaces.

6. The coaxial microwave rotary applicator of claim 1 , further comprising:
a first viewing window, being formed on one side of the chamber; and
a second viewing window, being formed on one side of the hollow cylinder.

7. The coaxial microwave rotary applicator of claim 6 , further comprising:
a light source, being used for providing an illumination light into the chamber.
