Description

Technical Field

[0001] This utility model relates to the field of slurry making technology for cast iron equipment, and specifically to a slurry making device for cast iron equipment. Background Technology

[0002] In cast iron production, the slurry preparation process has a significant impact on the quality of the final product. Traditional cast iron slurry preparation equipment has many drawbacks. On the one hand, the stirring method is simplistic, often using simple blade agitators, which makes it difficult to fully mix the raw materials, resulting in uneven slurry composition and affecting the performance stability of the cast iron. For example, if the spheroidizing agent, inoculant, and molten iron are not mixed sufficiently, it can cause inconsistencies in the internal structure of the casting, leading to localized defects.

[0003] Traditional pulping equipment has poor adaptability to raw materials, making it difficult to effectively process different types and particle sizes, resulting in low pulping efficiency. Furthermore, cleaning and maintenance of the equipment are difficult, with residual pulp easily accumulating inside, breeding impurities, and further affecting pulp quality. The cleaning process also consumes significant manpower and time, increasing production costs. Therefore, this device provides a pulping unit for cast iron equipment. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a slurry preparation device for cast iron equipment, thereby solving the aforementioned technical problems.
