Description

Technical Field

[0001] The utility model relates to the technical field of heat-insulating material drying kilns, in particular to an energy-saving heat-insulating material drying kiln. Background Art

[0002] A kiln is a furnace used to fire ceramics and sculptures or to fuse enamel to the surface of metal objects. During the production process of thermal insulation materials, the thermal insulation materials may absorb a certain amount of moisture, causing the thermal conductivity of the materials to increase, thus affecting their thermal insulation effect. Kiln drying can effectively remove this moisture, ensuring that the materials have a lower thermal conductivity and better thermal insulation performance.

[0003] In the production process of modern thermal insulation materials, the drying process is a key link to ensure the performance of the materials. The traditional drying technology usually involves laying the thermal insulation materials flat on the carrier plate in the kiln, and then closing the kiln for heating. However, when the thermal insulation materials are placed directly on the carrier plate, the side in contact with the carrier plate often cannot receive enough heat, resulting in a different degree of drying between the side in contact with the carrier plate and the side exposed to the hot air flow, leading to uneven drying of the overall material and affecting the thermal insulation performance of the material. At the same time, the closed environment in the kiln makes it impossible to effectively remove the moisture generated during drying, and the humid environment in the kiln easily causes the material to re-moisten, thereby reducing the drying efficiency.
