Abstract
The utility model belongs to the preparation of nano -materials field relates to a self -propagation high -temperature synthesis device for nanometer materials. Including two separable stainless steel cavities, upper portion is result collection room, and the lower part is the reacting chamber, the reacting chamber top is opened porosely, collects the room intercommunication with the result, the reacting chamber is inside to have graphite crucible to communicate with the collection slag chute as reaction vessel, graphite crucible bottom trompil, a reacting chamber lateral wall on open and to have the aperture, make the blasting fuse draw. Roof portion cooling trough is collected to the result. Reacting chamber and result are collected the room material and are 304 stainless steels. Its advantage is: the structure is simple and easy to whole upper portion cavity is showing the collection volume who has improved the result as the collecting region of result, collect roof portion at the result and set up the cooling trough, guarantee the whole result process of collecting and go on under lower temperature, avoided nanocrystalline growing up.
Description
Technical field
This utility model belongs to technical field of nanometer material preparation and in particular to a kind of self propagating high temperature of nano material closes
Become device.
Background technology
At present, common preparation method of nano material mainly has：Hydro-thermal method, chemical vapour deposition technique, physical vapour deposition (PVD)
Method, carbothermic method, calcination method, sol-gal process, masterplate method etc..Often preparation technology is complicated for these methods, equipment investment mistake
Greatly, energy consumption is too high, and the nano material purity being obtained is relatively low.SHS technology, mainly by the oxidation of thermite
Reduction reaction, induction system Physical Chemistry of Metallurgy reaction formed combustion wave, abrupt release heat melts spray system product so as to
Controlled cooling is thus obtain nano material.The method has that preparation section is few, operating process is short, process is simple, low energy consumption, low one-tenth
Originally the advantages of, product purity is high, has wide market-oriented prospect.
Because SHS process has very strong system specific aim, often prepare the used dress of different types of product
Put and also differ widely.At present, known self-spreading high-temperature synthesizing device is mainly for compact block material and cellular solid
Synthesis is it is impossible to directly obtain scattered nano material.Only patent CN201220398585 and CN201220175591 discloses point
The self-spreading high-temperature synthesizing device of scattered nano material.But the two all to there is high cost, complex structure, product collection amount low not
Foot.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of with low cost, structure is simple, yield is high dispersion
The self-spreading high-temperature synthesizing device of nano material.
The self-spreading high-temperature synthesizing device of nano material of the present utility model, including two separable rustless steel chambers,
Top is product collection room, and bottom is reative cell, and described reactor top is had hole, connected with product collection room；Described reaction
Chamber interior has graphite crucible as reaction vessel, and graphite crucible bottom opening is connected with dreg collecting slot, described reative cell side wall
On have aperture, so that fuse cord is drawn.
Described product collection ceiling portion is bosh.
Described reactor top has hole, enters reaction collecting chamber in order to product.
Have aperture on described reative cell side wall, so that fuse cord is drawn, in order to reaction initiation.
Described reative cell and product collection room material are 304 rustless steels, and the two is separable.
Described graphite crucible bottom opening is connected with dreg collecting slot.During use, paper gasket is put in the aperture of graphite crucible.
The advantage of the self-spreading high-temperature synthesizing device of this utility model nano material is：Simple structure, only can be divided by two
From rustless steel chamber constitute, not only reduce cost, also allow for prepare after cleaning；Dropped further using lead sparking mode
Low cost；Reaction zone and product collection are separated out the purity it is ensured that product；Using whole upper chamber as the collection of product
Area, significantly improves the collecting amount of product；In product collection ceiling portion, bosh is set it is ensured that whole resultant product collection process exists
Carry out at a temperature of relatively low, it is to avoid nanocrystalline grow up.
Brief description
Fig. 1 is the structural representation of the self-spreading high-temperature synthesizing device of this utility model nano material.
Wherein, 1- reative cell, 2- product collection room, 3- graphite crucible, 4- dreg collecting slot, 5- aperture, 6- bosh.
Specific embodiment
Below in conjunction with the accompanying drawings, this utility model is further described.
According to Fig. 1, a kind of self-spreading high-temperature synthesizing device of dispersion nano material, including two separable rustless steel chambeies
Room, top is product collection room, and bottom is reative cell, and described reactor top is had hole, connected with product collection room；Described anti-
Chamber interior is answered to have graphite crucible as reaction vessel, graphite crucible bottom opening is connected with dreg collecting slot, described reative cell side
Have aperture on wall, so that fuse cord is drawn.
Described reactor top has hole, enters reaction collecting chamber in order to product.
Have aperture on described reative cell side wall, so that fuse cord is drawn, in order to reaction initiation.
There is bosh in described product collection ceiling portion, to prevent the roughening of nanometer product.
Described reative cell and product collection room material are 304 rustless steels, and the two is separable.
Described graphite crucible bottom opening is connected with dreg collecting slot, and during use, the aperture of graphite crucible is provided with paper gasket.
This utility model is realized in：Weigh Al, CuO and ZnO powder by a certain percentage, and they are uniformly mixed, be used as
Reaction raw materials.Then, paper gasket is put into graphite crucible bottom and block aperture, then the reaction raw materials mixing are loaded graphite earthenware
In crucible and sprinkle pyrophoric powder, then by graphite crucible as on dreg collecting slot, reative cell on cover, plug fuse cord, and by reaction
Fuse cord is drawn by the aperture on the wall of room one, then covers upper product collection room, and the bosh at its top adds as cold in right amount
But water.Finally light a fire, ignition reaction raw material, realize Combination Process of SHS.Take off product collection room after about 30 seconds, fall away
Cooling water, you can from collection chamber interior walls and reative cell external wall of upper portion scraping nano zine oxide product.
Involved related chemistry reaction mainly has：
2AI+3CuO→Al2O3+3Cu
2Al+3ZnO→Al2O3+3Zn
2Zn+O2→2ZnO
