Abstract
The utility model discloses a device for self-spreading high-temperature synthesizing new material, comprising a synthesis reaction kettle, a water jacket, a vacuum valve, a heat insulation tube, a spiral clamp and a cover plate. The water jacket is arranged outside the synthesis reaction kettle, in which the heat insulation tube is provided; the vacuum valve is arranged on the synthesis reaction kettle; the spiral clamp is arranged on the salient edge of the upper part of the synthesis reaction kettle; the synthesis reaction kettle is sealed by the cover plate via the spiral clamp; a pre-pressing plate is arranged in the synthesis reaction kettle; the center of the cover plate is provided with a spiral push rod. The synthesis reaction kettle of the utility model can make the pre-pressing on the powder stock to obtain the combination of the pre-pressing and the spontaneous combustion in the synthesis reaction kettle; compared with the device adopting the independent powder green compact and the device adopting the combustion synthesis, the device for self-spreading high-temperature synthesizing new material has simpler structure, and simultaneously the damage of the green compact in the displacement process is avoided.
Description
Technical field
The utility model relates to a kind of novel material combustion and synthesis device, the device of the synthetic novel material of particularly a kind of self propagating high temperature.
Background technology
At present, known combustion and synthesis device has three kinds.A kind of is the auto-combustion device that raw material powder is not loaded; Second kind is to pressurize in the raw material powder auto-combustion to synthesize the device of high compactedness material; The third is that raw material powder is become highdensity pressed compact by mechanical compaction earlier, and then is put into the novel material of synthetic high-compactness in the synthesizer.
First kind of device is mainly used in the material of synthetic low density.Second kind of device incendiary will be realized synchronous loading simultaneously, is the sealing of assurance device, can cause the equipment complexity.The third device powder compact and burning are synthetic will be carried out respectively in two covering devices, and too high pressed density, cause the auto-combustion expansion on the contrary, cause anti-densification, reason is that pressed density is bigger, and particle room machine snap-in force is big, even cold welding, the particle rearrangement mechanism of liquid phase auto-combustion can not be played a role, and particle is reset the contribution maximum to densification.Simultaneously, compact strength is not high, causes easily that in the dislocation process pressed compact damages.
Summary of the invention
The purpose of this utility model is that the self propagating high temperature that provides simple in structure synthesizes the device of novel material, this novel material synthesizer is integrated with powder stock precompressed and the synthetic two kinds of functions of auto-combustion, like this can simplified apparatus, reduce ignition temperature, realize the preparation of medium compactedness material.
The technical scheme that its technical problem that solves the utility model adopts is: comprise synthesis reaction vessel, water jacket, vacuum valve, heat insulation tube, prefabricating plate, spiral binding clasp, cover plate, described water jacket is installed on the outside of synthesis reaction vessel, be provided with heat insulation tube in the synthesis reaction vessel, vacuum valve is installed on the synthesis reaction vessel, the spiral binding clasp is installed on convex edge, synthesis reaction vessel top, cover plate is sealed synthesis reaction vessel by the spiral binding clasp, be provided with prefabricating plate in the synthesis reaction vessel, the central authorities of cover plate are provided with spiral handspike.
Above-mentioned cover plate is provided with two spark electrodes, and tungsten filament links to each other with the electrode of cover plate lower inside.
Advantage of the present utility model: be provided with prefabricating plate in the synthesis reaction vessel, can in synthesis reaction vessel, carry out precompressed like this to powder stock, the combination of precompressed and auto-combustion in the realization synthesis reaction vessel, it is simpler to make its texture ratio adopt powder compact and burning to synthesize two covering devices respectively so on the one hand, avoids the damage of pressed compact in the dislocation process simultaneously.
