A kind of equipment of atomization production zinc powder
Technical field
It the utility model is related to zinc powder processing technique field, and in particular to a kind of equipment of atomization production zinc powder.
Background technology
Powdered metallic zinc is in Dark grey, has the function that good reproducibility and antirust and resistance to atmospheric corrosion, can make
Pigment, covering power is extremely strong, commonly uses to manufacture antirust paint, anticorrosive paint, strong reductant etc.;Meanwhile metal zinc due to compared with
Negative standard electrode potential, and larger specific surface area and chemism, the displacer being commonly used in metallurgical and chemical industry.
The production method of metal zinc mainly has following two:
The first:The way of distillation, this method are that solid zinc is heated into 1300-1350 DEG C to be allowed to become zinc fume condensed device again
It is cooled zinc powder.Way of distillation zinc powder has a particle diameter fineness of very little, but due to producing the high-temperature closed limitation of stove and cold
Condenser goes out powder operation and is difficult to hermetically sealed, causes effective zinc of way of distillation zinc powder to can only achieve 96%-97% or so.The way of distillation
Zinc powder particle diameter is meticulous and effective zinc is relatively low should not be used as the metallurgical displacer with chemical industry.
Second:Atomization, this method are produced by loading the zinc liquid of the nozzle at high speeds injection molten condition of compressed gas
Raw zinc powder, although atomization zinc powder average grain diameter is than way of distillation zinc powder more slightly, its effective zinc can make it up to more than 99%
With good reducing activity, product is largely used as the displacer of metallurgical and chemical industry.
Atomization process of the prior art is as shown in figure 1, be specifically:Zinc raw material is melted in melting furnace 1 ';Fusing
Zinc liquid afterwards sprays into combination settling bin 2 ' (settling bin herein has five storehouses and five hoppers) and bag collection through spray gun 3 '
The combination of part 4 ' obtains zinc powder, and zinc powder is sieved to obtain thickness different through conveyer 5 ' and elevator 6 ' into screening machine 7 '
Zinc powder, waste gas etc. through air draft airduct 8 ' discharge.The defects of such a technique has be:(1) take up an area greatly, making need to consume big dimension
Plate;(2) zinc powder is easily nucleated conglomeration, causes zinc powder coarse granule excessively or even ties gold-plating, influences product quality;(3) yield poorly, about 4-6
Ton day.
Therefore, a kind of equipment of suitable production zinc powder is designed to have very important significance.
