Further, the top of the finished bin is equipped with the atomizer for spraying dispersing agent.
Further, drapery panel is additionally provided in the electric heating converter, stay flitch.
Further, the electric heating converter uses 2520 materials.
A method of preparing electron level nanometer calcium molybdate, specifically includes the following steps: by high-purity nm molybdenum trioxide with
It is sufficiently mixed in the high-purity nm calcium carbonate resonance mixing machine of 1:1.02 addition in molar ratio, the material mixed is sent by feeder
Enter in electric heating converter, furnace temperature is 540 ± 1 DEG C, and the electron level nanometer calcium molybdate finished product of generation enters in finished bin, other part
Material is with CO2It brings recover into, then send to feeder and continue to use.
Further, material stops 40min in electric heating converter.
Further, ethylene glycol nanometer of the atomizer for the injection 1% into electron level nanometer calcium molybdate finished product
Material dispersing agent.
Compared with prior art, the beneficial effects of the present invention are:
A kind of device and method preparing electron level nanometer calcium molybdate proposed by the present invention, using high-purity nm molybdenum trioxide
It is directly synthesized in electric heating converter with high-purity nm calcium carbonate, simple to operate, combined coefficient nearly 100%, lossless, nothing
Pollution is, it can be achieved that be mass produced, and calcium molybdate partial size obtained meets industrial production use demand.
