Problems solved by technology

Among them, the vapor deposition method has high requirements on equipment and high cost; the sol-gel method and microemulsion method have serious pollution, and the product obtained has low purity and uncontrollable particle size; although the precipitation method has a simple production process and low equipment requirements, it can obtain The product purity is not high, and the particle size is difficult to be effectively controlled; the hydrothermal method can obtain a product with high purity, narrow particle size distribution, and controllable particle size, but the reaction process needs to be carried out under high temperature and high pressure environment, which requires more equipment. High, there is a certain risk in the production process
[0004] At present, nanotechnology is a cutting-edge technology, and related technologies and processes are in the research and development stage. The existing nano-powder material production system not only has high requirements for equipment, but also the performance and purity of the prepared nano-powder material are not ideal.

Embodiment 1

[0046] Such as Figure 1 to Figure 2As shown, a nanopowder material preparation system of the present invention includes a low-temperature reaction kettle, a horizontal centrifuge, a high-temperature hydrothermal reaction kettle, a centrifugal spray dryer, a calcining rotary kiln, and packaging equipment. The low-temperature reaction kettle, Horizontal centrifuge, high temperature hydrothermal reaction kettle, centrifugal spray dryer, calcining rotary kiln and packaging equipment are connected in sequence. Before the production of nano powder materials, the preparation of raw materials is required, and the prepared raw materials are placed in a low-temperature reactor for precipitation reaction, and a slurry is formed after the reaction. The slurry is placed in a horizontal centrifuge, and the horizontal centrifuge separates the solid phase and the liquid phase of the slurry. The solid phase collection bin 18 and the liquid phase collection bin 19 of the horizontal centrifuge ...

Embodiment 2

[0081] Such as Figure 11 As shown, the difference between this embodiment and Example 1 is that a first jet mill is connected between the centrifugal spray dryer and the calcining rotary kiln, and a second jet mill is connected between the calcining rotary kiln and the packaging equipment. Two jet mills; the centrifugal spray dryer separates the nano-powder from water to obtain atomized nano-powder. When the nano-powder settles, there may be bonding. At this time, the nano-powder passes through the first After the jet mill is crushed, the nano-powder is broken up, and then calcined in a rotary kiln to evaporate the water of the nano-powder. During the calcination process, the nano-powder may also be bonded. After the two-jet mill is crushed, the nano-powder is fully dispersed, and then packaged.

[0082] The rest of this embodiment is the same as Embodiment 1, and will not be repeated here.
