Description
Technical field
The invention belongs to chemical consersion unit, is specifically related to a kind of microwave pressure sintering furnace.
Background technology
Microwave chemical is since last century late nineteen eighties are worldwide used as frontier science emerging, in chemistry etc.
Grown rapidly in industry-by-industry.The practicality that scientific research at present, production all have microwave chemical reaction apparatus higher needs
Ask, how to allow the efficient, microwave chemical reaction apparatus of energy-saving and environmental protection to meet the different production requirement of industry-by-industry, in reaction pressure
Power, operating power, temperature control etc. all propose traditional microwave chemical reaction apparatus new challenge.
Document：Frequency conversion high-temperature steam micro-wave oven key technology research, it is indicated that, in general microwave reaction device, same
To find the preferable waveguide mouth of a coupling ratio inside one resonator is also relatively difficult thing, and matching one meets performance
It is required that waveguide mouth work almost account for more than the 80% of whole product experimental work amount.And microwave high-temperature reaction kettle not only needs
In view of microwave excitation problem, it is also necessary to consider high pressure pressure-bearing problem, design difficulty bigger.It is only simple to consider one side, without
Consider that the designing scheme of another aspect does not all meet actual demand.
The feed-in method and feed-in structure of microwave device are to realize the key and difficult point of air pressure, and by feed-in mode and feed-in
The limitation of structure, feed-in structure are difficult to ensure that the compressive property of feed-in part, and air-flow is be easy to cause from micro- by excessive pressure
Wave apparatus leaks so that internal pressure kept declines, heat losses rate is high, while the liquid stream leaked easily impacts microwave source, leads
The disabler of microwave source, equipment damage are caused, and there are great security risk.
At present, the feed-in bearing structure of microwave device mainly has：
One, using waveguide-blind plate feed-in pressure-bearing mode of conventional microwave device.
Two, using round bottom test tube type wave transparent element pressure-bearing mode feed-in.
Patent CN200610046206, using rectangular waveguide flange, quartz plate seal and pressure bearing, common is BJ26 microwave squares
Shape waveguide flange, rectangular opening size are 43.2*86.4mm；Such a microwave feed-in mode, in the rectangle opening of furnace body, seriously affects
The furnace body pressure design of autoclave；Due to microwave in the solution, it is particularly in aqueous solution, its penetration depth is limited, aqueous solution
In general penetration depth be no more than 3-8cm, reaction kettle needs up-sizing to produce, and in sintering process, is particularly large scale material
Microwave sintering when, due to microwave, penetration depth is limited in the material, such as the stronger carborundum of absorbing property or silicon nitride material
Material sintering, its penetration depth is no more than 5-10cm, therefore, either from increasing microwave heating power, or from homogeneous heating angle
Degree or microwave feed-in depth angle consider, be required to multiple microwave devices and uniformly match uses, because use rectangular waveguide energy regenerative when,

More than, the exposed length of the standard magnetron antenna of industrial common 2450MHz and 915MHz and rectangular cavities are difficult to
With combination of stimulation microwave.
In the prior art, limited by microwave energy-feeding bearing structure, greatly increase reaction unit pressure design and
Difficulty of processing and the use scope for limiting microwave high pressure sintering equipment.
In microwave sintering, there are weak, the multiple energy feedback devices of need since the electromagnetic field of sintering zone has by force in different zones
Uniform matched design, homogenizes the electromagnetic field of sintering zone, simultaneously because sintering temperature is higher, it is necessary to which big heating power, also needs
Multiple energy feedback devices are set in equipment, to increase the heating power of equipment.Particularly after large-scale production, heating often needs
