Description

Technical Field

[0001] The utility model relates to the technical field of inorganic non-metallic powder processing, in particular to a constant temperature ultra-fine inorganic non-metallic powder wet grinding and modification device. Background Art

[0002] The wet surface modification process is a process of adding configured surface modifiers and additives to a slurry with a certain solid-liquid ratio or solid content, and modifying the surface of the powder under stirring and dispersion at a certain temperature. It can change the physical and chemical properties of the surface of the powder material to meet the needs of the development of modern new materials, new processes and new technologies. Naturally, in the production and processing of inorganic non-metallic powders, their surfaces also need to be modified.

One end of the top of the top cover 11 is fixedly connected to a modified additive feeding pipe 3, and a fixing frame 2 is fixedly connected to the middle position of the top of the top cover 11. The top of the fixing frame 2 is fixedly connected to a pneumatic telescopic rod 1, and the output end of the pneumatic telescopic rod 1 passes through the upper end of the fixing frame 2 and is fixedly connected to a sliding plate 13. The bottom end of the sliding plate 13 is fixedly connected to a water mill motor 12. The output end of the water mill motor 12 is fixedly connected to a stirring rod 18 passing through the top cover 11 through a coupling, and stirring blades 15 are fixedly connected to the surface of the stirring rod 18 at equal angles.
