Further, described chiller is vertical cylinder, and top is provided with annular conduit, has outside described annular conduit
Water inlet pipe, inner side has one and irises out water hole.
The invention has the beneficial effects as follows: this device uses the cylinder of tilt adjustable, rotating metal tube and cooling
Device forms, and cylinder can move in a circle with self, according to the motion mode of the different material of rotating speed during work
Can be divided into and rush down formula, leave formula and centrifugal motion.Rush down formula and leave formula and have the effect of batch mixing, Ore can be made loose, also
Microwave treatment Ore can be allowed the most uniform.The time of microwave treatment Ore is changed, for different Ores by adjusting inclination angle
Use different angles, in addition, tilt to make the most spontaneous the moving downward of Ore, reach continuous work
The purpose made；It is capable of microwave the continuous high-efficient of Ore is processed.
In apparatus of the present invention, Ore is drastically heated after entering microwave region, and the Ore processed enters chiller,
Make Ore be cooled down in time, be unlikely to sizing.And using vertical cylinder, top is provided with the chiller of annular conduit and has cold
Uniform advantage.Due to heterogeneity dilatancy and inotropic difference in Ore, Ore is caused easily to produce crack, favorably
Process further in Ore.
In apparatus of the present invention, microwave generator group is by fixing connected mode, is connected to outside microwave transparent layer, along cylinder
Axially it is spaced substantially equidistant 2～8 groups in microwave treatment zone, has often organized and radially even 4～32 microwave generators are distributed, can
To increase and decrease as required, such arrangement processes Ore, and uniformly and microwave utilization rate is high.And there is microwave outside two ends and cylinder
Overcoat, such microwave will not be revealed human body generation harm, this technology use safety, can put into commercial production, it is simple to raw
Produce practice.
The present invention has simple in construction, continuous high-efficient safe and convenient to use, that be capable of Ore processes, it is real to be easy to produce
The advantage trampled.
