Description

Technical Field

[0001] This utility model belongs to the technical field of rock wool production equipment, specifically relating to a cooling device for rock wool production. Background Technology

[0002] Rock wool is an excellent thermal insulation, sound absorption, and heat insulation material, widely used in construction and industrial fields. In the production process of rock wool, molten rock is spun into fibers under centrifugal force and collected into felt, which is then cured in a curing furnace to form high-temperature rock wool boards. The rock wool boards fresh from the curing furnace are extremely hot (typically exceeding 200°C) and must undergo effective cooling before subsequent processes such as cutting and packaging.

[0003] Existing rock wool cooling methods are mostly natural cooling or single air cooling. Natural cooling is inefficient, occupies a large area, and seriously restricts production efficiency. Although single air cooling improves efficiency, for thicker rock wool boards, it is easy to cause the surface to cool too quickly while the inside cools too slowly, resulting in deformation and warping of the product due to uneven cooling, affecting the dimensional stability and mechanical properties of the product. Summary of the Invention

[0004] To overcome the problems of low efficiency, large footprint, and severe restriction on production efficiency caused by natural cooling in the prior art, and although single air cooling improves efficiency, it is prone to causing excessively rapid surface cooling and slow internal cooling for thicker rock wool boards. This uneven cooling leads to deformation and warping of the product, affecting its dimensional stability and mechanical properties. Therefore, this utility model provides a cooling device for rock wool production.
