This application relates to the technical field of metal powder drying, and provides a high-activity metal powder oxidation-proof drying device and drying method. The drying device includes: a drying box, an inert gas supply component, a vacuum component and a liquid level monitoring component; There are heaters, material trays, thermometers and vacuum gauges. The inert gas supply component is used to fill the dry box with inert gas. The vacuum component is used to vacuum the dry box. The liquid level monitoring component is used to collect absolute ethanol and monitor Changes in the liquid level of absolute ethanol. The cooperation between the inert gas supply component and the vacuum component can prevent the residual oxygen from causing the highly active metal powder to be oxidized; the heater and thermometer are used to achieve constant temperature heating and shorten the drying time; through the liquid level monitoring component, absolute ethanol can be controlled Collect and monitor the liquid level to ensure that the work can be stopped in time after the absolute ethanol 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 particularly, relates to a high-activity metal powder anti-oxidation drying device and a 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 decreases, the activity is greatly improved, and it is very easy to oxidize. Therefore, absolute ethanol immersion is often used in ball milling to protect the metal powder from being Therefore, the high-activity metal powder to be dried is often immersed in anhydrous ethanol. When the high-activity metal powder needs to be used, it needs to be dried first. The existing drying oven for drying the ball-milled high-activity metal powder has the following disadvantages: first, the residual oxygen in the oven is relatively high in the initial stage of d...
