[0002] Modified clay is a material that is modified by chemical or physical methods to improve its performance and meet specific application requirements. A screening machine is needed to initially screen the clay to remove impurities such as small stones inside. After multiple operation steps, organic or inorganic modifiers such as surfactants, organic polymers, metal ions, etc. are added to change the surface properties and interlayer structure of the clay. The modification can improve the dispersibility, stability, adsorption capacity, etc. of the clay.

[0003] Before the preparation of the existing modified clay, the screening mechanism used is customized with a corresponding multi-layer screening frame, which is then welded to the screening machine shell to screen clay powders of different specifications;

[0004] However, different modified clays require different clay powder specifications, so multiple models of multi-layer screening frames are needed for screening operations. Therefore, a screening mechanism that can easily replace the internal multi-layer screening frame without welding is needed. Utility Model Content
