Abstract
The utility model discloses a horizontal type vacuum AC electric arc furnace with a self-consumed electrode, which comprises an alternating current power supply, a synthesis chamber, an electrode driving device, a water cooling system, a vacuum system and an inflation system. The utility model can be used for the multitudinous synthesis of the nanometer micro powder of carbon covered metal. The complete set of the synthesis device has the advantages of simple structure, convenient operation and low cost, and is suitable for commercial scale production.
Description
The utility model relates to a kind of horizontal vacuum from the consumable electrode arc stove.This synthesizer is selected AC power for use, by two interelectrode distances of electrod driving device control, makes the stable alternating current arc of formation between two electrodes, and product is deposited on the intercooler wall.
The carbon covered metal nano powder has superior magnetism characteristic.Isolate mutually owing to wrapped up by carbon between the metallic particles, therefore this new version has not only demonstrated nanometer size effect but also has overcome nano metal material because of defectives such as the excessive heat that shows of surface energy, chemically unstables, has crucial application prospect in the material field.At present, existing technology of preparing is to adopt direct current arc method (Science, 1993,259:346; Jpn.J.Appl.Phys., 1994,33:L526), synthesizer be the laboratory skinny device (J.Appl.Phys., 1996,80:3062), have only single electrode consumption when synthetic, synthetic yields poorly, later separation is numerous and diverse.
Characteristics such as the purpose of this utility model provides a kind of device of new and effective synthetic carbon covered metal nano powder, and this device should have simple in structure, and is easy to operate, and cost is low, and can be used for the synthetic of carbon covered metal nano powder in enormous quantities.
For achieving the above object synthesizer of the present utility model-, form by the synthetic chamber of vacuum seal water-cooled, vacuum system, gas charging system, AC power, movable electrode drive unit and water-cooling system from the consumable electrode arc stove.Synthetic chamber and dodge gate have peep hole for flexibly connecting on the dodge gate, be convenient to the observing response process and take out product; Vacuum system links to each other with synthetic chamber by isolating valve; Gas charging system can pour the required inert gas of reaction in synthetic chamber; The movable electrode of a level installation and the fixed electrode of a relative installation with it are arranged in synthetic chamber, exchange outside by synthetic chamber power supply give two electrodes in addition voltage be that 20～60V, electric current are the alternating current of 200～1500A, relative distance by between electrod driving device control movable electrode makes the stable alternating current arc of formation between two electrodes; Synthetic cavity wall provides circulating condensing water to form intercooler by water-cooling system, and synthetic product can be deposited on the intercooler wall.
Compare with existing technology, alternating current from consumable electrode arc stove employing low-voltage and high-current of the present utility model is made power supply, use a fixed electrode and a movable electrode simultaneously, be fit to fairly large production carbon covered metal nano powder, two electrodes consume simultaneously when synthetic, and according to the consumption situation of electrode, regulate two interelectrode distances by the steering electrode drive unit, thereby guarantee to produce between two electrodes stable alternating current arc, therefore, it is big to have output with the synthetic carbon covered metal nano powder of this device, the productive rate height, the characteristics that cost is low are the comparatively ideal devices of industrial-scale production carbon covered metal nano powder.

Below in conjunction with accompanying drawing and specific embodiment the technical solution of the utility model is described further:
A kind of horizontal vacuum as shown in Figure 1, is made up of the synthetic chamber 1 of vacuum seal water-cooled, vacuum system 7, gas charging system 8, AC power 9, movable electrode drive unit 11 and water-cooling system 6 from the consumable electrode arc stove.Movable electrode 3 that a level installs and one electrode 4 that is relatively fixed with it is arranged in the synthetic chamber 1 of vacuum seal water-cooled.By two interelectrode distances of steering electrode drive unit 11 controls, make the stable alternating current arc of generation between two electrodes.
Use above-mentioned when the consumable electrode arc stove synthesizes the carbon covered metal nano powder, level is installed two isometrical carbon-points 5 that metal is housed respectively on two electrodes, two carbon-points are in contact with one another, close dodge gate 2, open the synthetic chamber of water-cooling system 6 coolings, start vacuum system 7, make synthetic chamber 1 interior vacuum reach 1.33 * 10
-2After handkerchief is above, close isolating valve 10, close vacuum system 7, open gas charging system 8 and charge into inert gas and make synthetic chamber internal gas pressure reach 1.33 * 10
4～7.98 * 10
4Handkerchief, connect AC power 9, by voltage 20～60V, the alternating current of electric current 200～1500A is handled movable electrode drive unit 11 simultaneously between the electrode bar, two carbon-points 5 are disengaged, the starting the arc continues steering electrode drive unit 11 control arc distance and voltages, keeps arc stability, carbon-point 5 carries out end face evaporation simultaneously under the high temperature of electric arc, form micro mist and be deposited on the inwall in synthetic chamber through chemical reaction in inert gas.Whole process can monitor by peep hole 12.Treat that two carbon-points are exhausted, the water supply of stopping power supply.In synthetic chamber, charge into dry air, open dodge gate 2, collect micro mist.
