Description

[Technical field]

[0001] The invention relates to the technical field of refractory materials, in particular to the technical field of a mixing device for refractory materials with high mixing efficiency. [Background technology]

[0002] Refractory materials refer to a class of inorganic non-metallic materials with a refractoriness of not less than 1580℃. Refractoriness refers to the Celsius temperature at which a conical specimen of a refractory material can resist high temperature without softening and melting under no load. However, defining it only by refractoriness can no longer fully describe refractory materials, and 1580℃ is not absolute. It is now defined as any material whose physical and chemical properties allow it to be used in a high temperature environment is called a refractory material. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields. They are used in the largest amount in the metallurgical industry, accounting for 50% to 60% of the total output. When producing refractory materials, the raw materials need to be mixed and discharged.

[0003] During operation, the existing mixer generally mixes materials by rotating the stirring paddle. The mixing method is single, resulting in a long mixing time and reduced work efficiency. Moreover, when the existing mixer mixes refractory raw materials, the raw materials are prone to agglomeration, thereby affecting the mixing effect. [Summary of the invention]
