Description

A molding sand preparation device Technical Field

[0001] This utility model belongs to the field of molding sand preparation technology, and in particular relates to a molding sand preparation device. Background Technology

[0002] Molding sand can be divided into face sand, filler sand, and single-layer sand. Face sand is a layer of molding sand that adheres tightly to the casting and has high quality requirements. Filler sand is placed after the face sand layer and does not come into contact with the molten metal; its quality requirements are not strict. Single-layer sand is molding sand without face sand and back sand, mainly used for machine molding. In addition, sand molds for large castings often need to be dried before pouring, and the molding sand used contains more clay; this type of molding sand is called dry mold sand. Medium and small castings often use wet mold pouring, and the molding sand used contains less clay; this type of molding sand is called wet mold sand.

[0003] Existing molding sand preparation equipment requires mixing raw materials such as raw sand together during use. A certain amount of water needs to be added during the mixing process. However, existing molding sand preparation equipment directly introduces water into the mixing tank through a water inlet pipe on one side, which makes it impossible for the water to mix evenly with the materials, seriously reducing work efficiency. Moreover, some raw sand contains impurities, which affects the preparation of molding sand.

[0004] To address these issues, we provide a molding sand preparation apparatus. Summary of the Invention
