Description

Technical Field

[0001] The utility model relates to the technical field of slurry stirring equipment, in particular to a shell making slurry rapid stirring device special for precision casting. Background Art

[0002] The shell slurry for precision casting is a slurry specially used for manufacturing precision casting shells. This slurry usually includes multiple ingredients, such as refractory powder, silica sol, adhesives and other additives. These ingredients work together to form the desired shell structure. The preparation process of shell slurry usually includes multiple steps, such as configuring surface slurry, transition layer slurry and back layer slurry. The selection of surface slurry is crucial to the quality and precision of the casting surface. Common surface slurries include EC95 powder surface layer and zirconium silicate surface layer. The transition layer slurry is mainly used to connect the surface layer and the back layer, and its refractory material usually uses EC95 powder. The back layer slurry pays more attention to the strength and stability of the structure. The refractory materials used may include EC95 powder, kaolin, etc., and different types of silica sols will also be used. During the preparation process, the various ingredients need to be mixed and stirred in a specific proportion to ensure the uniformity and stability of the slurry. In addition, it is also necessary to pay attention to controlling the physical properties of the slurry, such as viscosity and fluidity, to meet the needs of different castings. When stirring it, a rapid stirring device is generally required. However, at present, the slurry is poured into a barrel for stirring and then discharged after stirring. However, the slurry will adhere to the inner wall of the barrel during stirring, thereby affecting the stirring effect of the slurry next time. Utility Model Content
