Multi-stirring-shaft vacuum microwave oven special for powder and heating method

Abstract

The invention provides a multi-stirring-shaft vacuum microwave oven special for powder. The vacuum microwave oven comprises a heating oven body, a cooling oven body, a weighing sensor, lower vacuum channels, an upper vacuum channel, an exhaust channel, a microwave input pipe, a feeding pipe and a temperature measuring component; and high-speed stirring shafts and a low-speed stirring shaft are arranged in the heating oven body. According to the multi-stirring-shaft vacuum microwave oven special for the powder, the oven can work in a vacuum state and can also work in an atmospheric pressure state; the oven can work in a plasma environment microwave heating state and can also work in a non-plasma environment microwave heating state; the oven can work in a microwave heating state, can work ina resistance heating state and can also work in a microwave heating and resistance heating dual-heating state; the oven can work in an oxidizing atmosphere state, can work in a reducing atmosphere state and can also work in other atmosphere states; and based on the action of the multiple stirring shafts, the heat treatment on materials can be sufficiently performed.

Description

technical field [0001] The invention relates to the technical field of powder heat treatment, and more specifically, relates to a multi-shaft vacuum microwave oven dedicated to powder. Background technique [0002] The environment in the high-temperature furnace required for the heat treatment of powder products is different. Some powders need to be prepared in a vacuum state, while some need to be carried out in an atmospheric pressure environment; the atmosphere conditions required for powder heat treatment also include oxidizing atmosphere, reducing atmosphere, etc.; and for For the selection of heating methods, some powders only need traditional resistance heating, while for powders with higher quality requirements, microwave heating is required; the function of high-temperature heating furnaces in the prior art is relatively single, and a single heat treatment furnace can provide The heat treatment environment and heating methods are limited or it is not easy to change ...
