[0002] Oxygen carriers refer to a class of substances that can reversibly bind to oxygen molecules. During the chemical chain process, oxygen carriers avoid direct contact between fuel and oxygen by generating and releasing lattice oxygen, thereby reducing the cost of separation. Therefore, they play an important role in chemical chain reactions.

[0003] At present, during the preparation process of oxygen carriers, the raw materials need to be mixed, and then processed through tableting to obtain oxygen carrier particles of uniform size for subsequent use. Existing oxygen carrier raw materials are usually mixed in a blender, but during the mixing process, since the raw materials are divided into different properties such as powder, paste and solution, they are easy to merge with each other during feeding, resulting in blockage and jamming of the feeding port, which is not conducive to subsequent mixing. In addition, due to the different properties and density of the raw materials during the mixing process, the density and mixing degree of the upper and lower layers may be uneven, affecting the quality of the raw materials.

[0004] Therefore, in view of the problem that in the above-mentioned existing oxygen carrier raw material mixing process, the raw materials have different properties and are easy to merge with each other during feeding, resulting in blockage and jamming of the feeding port, and uneven mixing may occur due to the different properties and densities of the raw materials during the mixing process, which affects the quality of the raw materials, a mixing device for oxygen carrier granulation preparation can be designed. By setting up a feeding structure for different raw material properties, the feeding process is facilitated and the feeding efficiency is improved. By setting up a stirring structure for up and down stirring, the raw materials can be mixed more fully. Utility Model Content
