Embodiment 1

[0026] Example 1: The nanoparticles to be reduced are loaded into the container, the reactor is fixed on the base of the furnace body and the gas nozzle is rotated to connect with the gas path, the furnace cover is closed by the lifting motor, and the propeller stirring rod is lowered at the same time. Put into the holding container and cover the top of the holding container. Lock the furnace cover, open the circulating cooling water valve, open the gas valve, set the stirring speed, heating process, and reaction parameters on the programmable touch LCD display of the operation and circuit control device, and set the gas flow on the gas circuit control device. The flow rate, the mixing ratio of the reducing gas, and the start-up procedure automatically complete the reduction process. The excess reducing atmosphere and the water vapor generated by the reaction are discharged through the exhaust device and combustible gases such as hydrogen are burned. During this period, observ...

Embodiment 2

[0027] Embodiment 2: The nanoparticles to be denucleated are loaded into the container, the container is fixed on the base of the furnace body and the gas nozzle is rotated to connect with the gas path, the furnace cover is closed by the lifting motor, and the propeller stirs at the same time The rod is lowered into the reactor and the cap is placed over the top of the reactor. Lock the furnace cover, open the circulating cooling water valve, open the gas valve, set the stirring speed, heating process, and reaction parameters on the programmable touch LCD display of the operation and circuit control device, and set the gas flow on the gas circuit control device. The flow rate, gas mixing ratio, and start-up procedure automatically complete the organic nuclear cracking process, and the excess atmosphere and cracking steam produced by the reaction are discharged through the exhaust device. During this period, observe the dynamic fluidization state of nanoparticles through the ob...

Embodiment 3

[0028]Embodiment 3: The nano-particles to be denucleated and reduced are loaded into the container, the container is fixed on the base of the furnace body and the gas nozzle is rotated to connect with the gas path, the furnace cover is closed by the lifting motor, and at the same time The propeller stirring rod is lowered into the reactor, and the cap covers the top of the reactor. Lock the furnace cover, open the circulating cooling water valve, open the gas valve, set the stirring speed, heating process, and reaction parameters on the programmable touch LCD display of the operation and circuit control device, and set the gas flow on the gas circuit control device. The flow rate, gas mixing ratio, and start-up procedure automatically complete the organic nuclear cracking treatment and reduction process. The excess atmosphere and cracking steam produced by the reaction are discharged through the ignition device and combustible gas is burned. During this period, observe the dyn...

Abstract

The dynamic fluid atmospheric oven for the making of sodium powder comprises oven components, oven cover lifting device, material container, air leakage protective device, operation and circuit control device and air control device, two air channels, spiral blending bar sticking vertically from the center of the top cover of the material container to the inner cavity of the container, with one being the channel blowing from the bottom of the container to the atmospheric air, the other entering into the inner heating well type atmospheric oven air channel. It can produce the effect of recovery, coating oxidation protective film, off core, and so on without sediment, sticky and damage.

Description

technical field [0001] The invention relates to a dynamic fluidized atmosphere furnace for preparing nano-micro powder materials. Background technique [0002] Nanotechnology is the commanding height of scientific and technological development in the 21st century and the leading technology of the new industrial revolution. The preparation technology of nanoparticles is one of the foundations and hotspots of nanotechnology, which requires high preparation equipment and processes. Generally, the complexity of nanoparticle preparation determines that it often needs to prepare precursor nanoparticle first, and then the precursor nanoparticle is reduced, coated with an oxidation protective film, denucleated, (directional) recrystallized and other reactions in the atmosphere furnace. Prepare the desired nanoparticles. [0003] At present, the existing atmosphere furnace is mainly composed of an internal heating atmosphere furnace, a furnace cover (door), a heating body, a gas lea...
