Problems solved by technology

[0004] In the process of producing nanometer metal powder by plasma arc evaporation, it is particularly important to grasp the temperature of the crucible. The prior art smelting and evaporation device has an observation tube in the observation tube There are multiple layers of high-temperature-resistant transparent glass. Operators use human eyes to observe the situation in the crucible in the melting and evaporating device through the multi-layer high-temperature-resistant transparent glass on the observation tube. Feed; and the smelting and evaporating device needs to be stopped when feeding, and the production efficiency is very low; and because the smelting and evaporating temperature is very high, the sensor for measuring the smelting and evaporating temperature is often easily damaged and the measurement is inaccurate, resulting in inaccurate control of the temperature of the smelting and evaporating device Accurate, so that the produced nano-metal powder particles are not uniform, resulting in the problem of poor quality of nano-metal powder; for this reason, it is very meaningful to develop efficient and stable production methods and equipment for nano-metal powder
