[0001] The invention relates to the technical field of concentrators, and in particular to a non-stirring concentrator. Background Art

[0002] In recent years, with the continuous growth of global energy demand, climate change and ecological environment issues have become increasingly prominent. Accelerating the development of new energy has become a common choice for countries around the world to maintain energy security, meet climate change, and achieve sustainable development. The optimization of the material production process and product quality of power batteries are of paramount importance. The concentration reaction filtration in the production process of manganese tetraoxide power battery materials is an important link. The concentration reaction method directly affects the production efficiency and labor cost investment. The traditional sedimentation method of the concentration tank not only has a low yield, a long reaction cycle, and relatively low quality. In order to solve the above problems, by optimizing and improving the existing filtration and concentration equipment, the production efficiency, product yield and labor cost investment have been greatly improved. Summary of the invention
