Description
Technical field
The utility model relates to the system that produces of indium powder.
Background technology
Thin indium powder is a kind of important industrial raw materials, and mainly for the preparation of TTO target and electronic product etc., its application prospect is very wide.Along with the indium powder increases in industrial demand, the producing equipment of thin indium powder, system etc. have obtained development to a certain degree.At present, produce thin indium powder and generally adopt electrolysis and the way of distillation.Because it is lower that electrolysis is made the indium powder output capacity of release mesh, and will spend a large amount of hand labours the spongiform sediment grinds of indium, not only production cost is high, efficient is low, and has hindered plant-scale trial-production of indium powder; And the way of distillation is that indium metal is heated to more than 2000 ℃, and the indium steam that volatilizes obtains the indium powder through condensation, although the indium Powder Particle Size of producing is even, used equipment need to adopt high temperature resistant material, and is expensive.
The utility model content
For above-mentioned technical problem, the utility model provides a kind of structure indium powder simple, that cost is lower, yield rate is higher to produce system.
The technical scheme in the invention for solving the above technical problem is: a kind of indium powder is produced system, the fusion pool that comprises liquefaction indium metal raw material, this fusion pool bottom one side is provided with the mozzle of deriving liquid indium, this mozzle is communicated with a horizontally disposed spray chamber, this spray chamber right-hand member is equipped with nozzle, nozzle stretches into a spray chamber, and the spray chamber bottom is equipped with a screen cloth, and the screen cloth bottom is connected with dust-precipitator; Be provided with the gas supply room, gas in the supply room is delivered to described spray chamber by compressor, in spray chamber, sprays into spray chamber by nozzle after gas mixes with liquid indium, gas in the spray chamber enters described dust-precipitator, and the gas in the dust-precipitator is discharged by exhaust blower.
Further, the air inlet of described exhaust blower is communicated with described dust-precipitator, air outlet is communicated with described supply room.
Further, be provided with the heater of motlten metal indium bottom the described fusion pool.
Further, the gas in the described supply room is inert gas.
Further, described heater is to described mozzle heat supply.
Further, described heater is to described spray chamber heat supply.
Further, described supply room is communicated with described melter.
As can be known from the above technical solutions, the utility model utilizes nozzle that gas-liquid mixture is sprayed into spray chamber, so that liquid indium uniform-mist changes into less indium powder particles, thereby avoid using exotic material that indium metal is distilled, not only refinement is even, yield rate is higher, and simple in structure, production cost is lower; Simultaneously, the utility model can recycle gas, has further reduced production cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with Fig. 1 the utility model is described in further detail:
This indium powder is produced the fusion pool 1 that system comprises liquefaction indium metal raw material, this fusion pool bottom one side is provided with the mozzle 2 of deriving liquid indium, this mozzle is communicated with a horizontally disposed spray chamber 3, this spray chamber right-hand member is equipped with nozzle 4, nozzle stretches into a spray chamber 5, and the spray chamber bottom is equipped with a screen cloth 6, and the screen cloth bottom is connected with dust-precipitator 7, dust-precipitator is collected the indium powder particles below the screen cloth, re-starts refinement and the indium powder particles on the screen cloth is recyclable to fusion pool.The utility model can need not indium metal is heated to more than 2000 ℃, makes it become the indium steam, and only needs fusion pool is heated to more than the fusing point of indium.In real process, the temperature of fusion pool generally maintains and is optimum temperature about 250 ℃, and such temperature reduces surface tension and the viscosity of liquid indium effectively simultaneously, is conducive to the spraying liquid indium.Therefore, the utility model can avoid using exotic material, and not only structure is simpler, and can reduce production costs.
The utility model is provided with gas supply room 8, gas in the supply room is delivered to described spray chamber by compressor 9, in spray chamber, sprays into spray chamber by nozzle after gas mixes with liquid indium, gas in the spray chamber enters described dust-precipitator, and the gas in the dust-precipitator is discharged by exhaust blower 10; As optimal way, the air inlet of described exhaust blower is communicated with described dust-precipitator, air outlet is communicated with described supply room, thereby makes the gas backstreaming that enters in the spray chamber to supply room, gas has been carried out recycling, further reduces production costs.In implementation process, the angle that gas enters the spray chamber direction preferably and the maintenance of the flow direction of liquid indium is certain, the size of angle is generally 60 °-90 °, when gas enters spray chamber so liquid indium is broken up, and can fully mix; Simultaneously, such angle is little to the flow rate effect of gas-liquid mixture, therefore, on the basis that guarantees productivity ratio, can be with the abundant refinement of liquid indium.In the utility model, the pressure of gas is relevant with the granularity of refinement indium powder, when having the same terms, improves the pressure of gas, can reduce the granularity of indium powder refinement, and the gas pressure of native system generally adopts 0.8MPa-1.5 MPa.Experiment shows that when gas pressure was brought up to 1.44MPa by 0.83MPa, the output capacity of the indium powder of-0.045mm granularity brought up to 97.5% by 46.2%.In implementation process, the selection of nozzle is also most important, should be according to the diameter of the needs choose reasonable nozzle of producing the indium Powder Particle Size.
In system, described fusion pool bottom is provided with the heater 11 of motlten metal indium, this heater can maintain the temperature of fusion pool 250 ℃, simultaneously, described heater is to described mozzle and respectively heat supply of spray chamber, prevent the drop in temperature of mozzle and spray chamber, so that the surface tension of liquid indium and viscosity increase, be unfavorable for abundant atomizing.Gas in the utility model supply room adopts inert gas, and described supply room is communicated with described melter, makes to be full of inert gas in the melter, can prevent that indium is oxidized.
