Abstract

The invention relates to the technical field of metal powder drying, and provides a high-activity metal powder anti-oxidation drying device and method. The drying device comprises a drying box, an inert gas supply component, an evacuation component and a liquid level monitoring component, wherein a heater, a material tray, a thermometer and a vacuum gage are arranged in the drying box; the inert gas supply component is used for filling inert gas into the drying box; the evacuation component is used for evacuating the drying box body; and the liquid level monitoring component is used for collecting absolute ethyl alcohol and monitoring the liquid level height change of the absolute ethyl alcohol. The inert gas supply component and the evacuation component are matched with each other, so that the situation that high-activity metal powder is oxidized due to residual oxygen can be avoided; the heater and the thermometer are used for realizing constant-temperature heating and shortening the drying time; and absolute ethyl alcohol can be collected and the liquid level can be monitored through the liquid level monitoring component, so that it is ensured that work can be stopped in time after absolute ethyl alcohol is completely evaporated, the drying time is shortened, the labor cost is reduced, and the drying efficiency is improved.

Description

technical field [0001] The application belongs to the technical field of metal powder drying, and more specifically relates to a highly active metal powder oxidation-proof drying device and drying method. Background technique [0002] At present, with the rapid development of powder metallurgy technology, the requirements for the particle size of metal powder are getting higher and higher. When the particle size of metal powder is reduced, the activity is greatly improved and it is easy to oxidize. Therefore, absolute ethanol is often used to protect the metal powder from being Therefore, the highly active metal powder to be dried is often immersed in absolute ethanol. When the highly active metal powder needs to be used, it needs to be dried first. The existing drying oven dries the highly active metal powder after ball milling, which has the following disadvantages: first, the residual oxygen in the oven is relatively high at the initial stage of drying, and the metal powd...
