[0002] Rapid-setting taphole mud is a high-performance refractory material primarily composed of refractory aggregates (such as aluminum silicate, SiC, and coke), binders (such as tar and resin), and additives. It exhibits excellent viscoplasticity, easy sintering, and resistance to erosion and corrosion. It is commonly used for plugging operations in high-temperature environments, such as blast furnace tapholes, to ensure safe and efficient production. Its processing requires mixing solid and liquid raw materials.

[0003] However, since quick-setting taphole mud materials usually contain a large amount of sulfoaluminate and have the characteristic of fast solidification speed, they will form lumps on the inner wall of the device during the mixing process.

In addition, the scaling device requires more time and manpower for cleaning and maintenance, which increases the complexity and cost of maintenance. In response to the above problems, the inventors proposed a solid-liquid mixing device for quick-setting taphole mud materials to solve the above problems. Utility Model Content
