Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to a device for rapidly and uniformly drying refractory materials. Background Technology

[0002] Refractory materials are 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, under no load, resists high temperatures without softening or melting. However, defining refractory materials solely by refractoriness is insufficient to fully describe them; 1580℃ is not absolute. Currently, refractory materials are defined as any material whose physicochemical properties allow it to be used in high-temperature environments. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, and power industries, with the largest usage in the metallurgical industry, accounting for 50%–60% of total production. Refractory materials are applied in various sectors of the national economy, including steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, power, and military industries. They are essential basic materials for ensuring the production, operation, and technological development of these industries, playing an irreplaceable and vital role in the development of high-temperature industrial production.

[0003] A device for rapidly and uniformly drying refractory materials is disclosed in Chinese utility model patent application publication CN218238163U. Although the device can dry relatively uniformly during use, it has the following drawbacks: First, the device can only dry from top to bottom, resulting in a slower drying speed at the top of the material and thus low drying efficiency. Second, during the drying process, a large amount of air with unpleasant odors and harmful gases is generated, and these gases can easily pollute the atmospheric environment when they enter the outside.
