[0002] Refractory materials usually refer to a class of inorganic non-metallic materials with a refractoriness of not less than 1580℃. Refractory materials are used in various fields of the national economy, such as steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electric power, and military industry. They are essential basic materials to ensure the production operation and technological development of the above industries. Refractory materials are usually made by mixing a variety of different materials.

[0003] After searching, the Chinese patent with publication number CN216630675U discloses a dust-free stirring device for refractory material production, including a mounting base, a stirring mechanism and a feeding dust-proof mechanism; the mounting base: the middle part of its upper surface is rotatably connected to a rotating table through a bearing, and a mounting bracket is provided on the rear side of the upper surface of the mounting base; the stirring mechanism: arranged in the middle part of the upper surface of the rotating table, and the lower end of the stirring mechanism is fixedly connected to the upper surface of the mounting base; the feeding dust-proof mechanism: arranged in a circular hole opened at the front end of the top plate of the mounting bracket, and the lower end of the feeding dust-proof mechanism is rotatably connected to the through hole opened in the middle part of the upper surface of the stirring mechanism. Among them: it also includes a gear ring, which is sleeved on the outside of the rotating table, and the feeding pipe is changed from a traditional straight pipe to an inclined curved pipe. The dust-free stirring device for refractory material production can prevent dust from flying out during the material mixing process, and provide a good working environment for the operator. However, the existing technology has the following shortcomings when used:

When the material is stirred, some dust will overflow from the inside of the mixing tank, which is likely to cause pollution to the surrounding environment.

[0005] Therefore, a dust-free stirring device for refractory material production is urgently needed to solve the above problems. Utility Model Content
