Abstract
The invention discloses a water-cooling dry-type lifting board applied to a roller slag-cooling machine. The water-cooling dry-type lifting board applied to the roller slag-cooling machine comprises a lifting board body, wherein the lifting board body is cast once, the inside of the lifting board body is of a hollow structure, and a water pipe is arranged at the bottom of the lifting board body. Compared with the prior art, the water-cooling dry-type lifting board can play a role in indirectly cooling materials through water to some extent in the material operating process. Due to the fact that the lifting board adopts a water scraping tile design mode, the water in the water scraping tile and the lifting board flows out along the outer wall of a barrel when the barrel operates, and the temperature of the barrel is reduced to some extent. By means of the two methods, the heat transfer coefficient among particles of materials and inside the materials is improved, and the heat transfer effect of the materials is improved.
