Description

technical field [0001] The invention relates to the technical field of chemical reaction generators, in particular to a vacuum rapid dispersion reactor. Background technique [0002] In the technical fields of petroleum, chemical industry, medicine, and alloy production, it is necessary to control the concentration of reactants, uniformity of reactant mixing, reaction temperature, reaction pressure, and product concentration in the production process. Reactor is an important equipment to realize the above functions. Many alloys, especially lithium alloys, need to be produced in a protective environment. For example, a certain amount of aluminum, magnesium, and silicon alloy elements are evenly dispersed into liquid metal lithium in a vacuum atmosphere to produce lithium battery anode materials. Lithium aluminum alloy, lithium magnesium alloy or lithium silicon alloy. [0003] The traditional reaction kettle includes the reaction kettle body composed of the kettle cover and ...

Problems solved by technology

Since the dynamic sealing structure is used to realize the sealing isolation between the interior of the kettle body and the outside world, there is relative movement between the moving parts and the stationary parts, and the sealing isolation between the reaction kettle and the outside world is poor, so it can only provide a low vacuum reaction environment

Alloy production in a low vacuum reaction environment will seriously affect the quality of the alloy reaction. For example, low vacuum for lithium-based alloys will produce new nitrides or oxides. The larger particle size of the nitrides or oxides will affect the quality of the alloy. The metallographic uniformity greatly reduces the comprehensive performance of lithium-based alloys

At the same time, in the existing reaction kettle, the stirrer blades are installed vertically on the stirring shaft, and the stirrer blades can only drive the alloy liquid to flow in the circumferential direction, but cannot drive the alloy liquid to produce the flow in the axial direction, and the dispersion effect of the alloy elements is poor. Uneven phase distribution
