Description

TECHNICAL FIELD

[0001] The utility model relates to the field of mixers, more specifically, to a mixer for refractory materials. BACKGROUND

[0002] Refractory materials are generally divided into two types, namely, unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also known as castables, are a mixture of powdery particles composed of various aggregates or aggregates and one or more binders. They must be mixed with one or more liquids before use to achieve uniformity and have strong fluidity. Shaped refractory materials generally refer to refractory bricks, which can have standard shapes or be temporarily processed according to needs. Refractory brick raw materials are mixed by combining different refractory materials in a certain proportion and process to produce refractory bricks with specific properties. The refractory materials for refractory bricks mainly include refractory clay, bauxite, and quartz sand. To facilitate the addition of large amounts of materials to the mixer, a top-open horizontal mixer is often used.

[0003] Based on the above, the inventor found that the existing mixers are not convenient for cleaning the residual materials in the equipment after mixing the refractory materials. Since the refractory materials have a certain stickiness and the discharge port of the mixing bin is small, manual removal and collection of the materials using tools is very tedious, time-consuming, and labor-intensive. Moreover, the discharge completeness of the mixing bin is low, resulting in a large amount of residual materials in the bin. Therefore, the existing structure is improved to provide a mixer for refractory materials to achieve a more practical purpose. SUMMARY
