Microwave irradiation heating can significantly improve chemical reaction rate because of its homogeneous heating, improves the performance etc. that reaction generates product, and therefore, the microwave irradiation heating has obtained application widely in fields such as chemical reaction and material are synthetic.The solution combustion synthetic method be a kind of (mainly be nitrate based on the oxidant in the solution; Also can be perchlorate) and fuel (comprising that organic matter has carboxylic acid, carboxylate, urea and hydrazine class itrogenous organic substance etc.) between the new method of the self-propagating combustion Reaction Synthesis Materials that is caused by heat or microwave low temperature; But it is synthetic to be to use common micro-wave oven to carry out microwave induced solution combustion, ignites can in microwave oven cavity, produce with combustion process to have corrosive gas and steam in a large number, not only rapid corrosion microwave furnace cavity; Also can diffuse into the electronic component part of micro-wave oven; The heavy corrosion electronic component causes short circuit, causes the use of microwave ovens life-span very short; Experimental cost is very high, and the experiment progress can receive very big influence.
Summary of the invention
The invention provides a kind of making and do not contact, directly be discharged to the high microwave utilization rate and the high temperature resistant reaction device of micro-wave oven outside with microwave oven cavity at the gas that microwave ignites with the solution combustion process is produced.
The technical scheme of dealing with problems that adopts of the present invention is.
The present invention is by micro-wave oven (A), and reaction vessel cavity top (B), reaction vessel cavity bottom (C), fixture (F), up-down support platform (D) and reaction vessel (E) are formed.Micro-wave oven (A) cavity top middle opening, the back is provided with microwave source (G), and the front is provided with the door of switch, and up-down support platform (D) places micro-wave oven (A) cavity inner bottom part; The top on reaction vessel cavity top (B) is the neck shape; Its size adapts with micro-wave oven (A) cavity top middle opening; And an opening that is open upwards is arranged; It passes micro-wave oven (A) cavity top middle opening and snaps in micro-wave oven (A) cavity top, and is fixed in the top central closing of micro-wave oven (A) by fixture (F); Reaction vessel cavity bottom (C) places on the up-down support platform (D), and reaction vessel (E) places in the cavity of reaction vessel cavity bottom (C); After up-down support platform (D) rises, the closed reaction vessel cavity that constitutes an integral body in reaction vessel cavity top (B) and reaction vessel cavity bottom (E).
Its cross section of reaction vessel cavity of the present invention can be square, also can be circular.The cross section on reaction vessel cavity top (B) is corresponding fully with the shape of cross section of reaction vessel cavity bottom (C), and both connect with joinery and its construction.
The used material of reaction vessel cavity of the present invention is not only complete transmission microwave but also resistant to elevated temperatures aluminium oxide or quartz or glass or pottery.
Reaction vessel cavity of the present invention top (B) passes the part of micro-wave oven (A) cavity top middle opening, coats with the micro-wave screening material, and its opening that is open upwards is covered with the micro-wave screening wire netting.
Wire netting or thin slice that micro-wave screening material of the present invention is a microwave reflection.
Roller can be established in the bottom of up-down support platform of the present invention (D), with convenient up-down support platform (D) is pushed in micro-wave oven (A) cavity.
Reaction vessel of the present invention (E) is glass or ceramics such as quartz or aluminium oxide.
Up-down support platform material therefor of the present invention can be stainless steel.
The reaction cavity transmission microwave of generator of the present invention, high temperature resistant, anticorrosion; Can make microwave cause the corrosive gas that the solution combustion course of reaction is produced; Do not contact, directly discharge outside the micro-wave oven, avoided the corrosion of the gas that combustion reaction produced microwave oven cavity and electronic component part with microwave oven cavity; Prolonged the use of microwave ovens life-span greatly, a kind of simple, safe and reliable reaction unit is provided for microwave induced solution combustion is synthetic.
