Description

Technical Field

[0001] The utility model relates to the technical field of brick production, in particular to a fine aggregate precooling device for brick production. Background Art

[0002] Bricks are a common building material made of clay, concrete, limestone or other materials. They are usually rectangular with a certain thickness and width and are used to build walls, floors and other building structures. The main characteristics of bricks are strength, durability and fire resistance. They can withstand heavy pressure and maintain structural stability. They play an important role in supporting and fixing buildings. Bricks also have thermal insulation properties and can play a role in heat preservation and fire prevention in buildings. In order to improve the strength of bricks, a certain proportion of fine aggregate is usually added, and pre-cooling treatment is required before adding.

[0003] The existing pre-cooling device cools the material by stirring and turning the material and blowing cold air on the surface of the material. This method can only pre-cool the material on the top layer and cannot pre-cool it evenly, which greatly increases the pre-cooling time, reduces efficiency and increases energy consumption. In addition, the existing pre-cooling device cannot screen the material in time after pre-cooling. After pre-cooling is completed, it must be screened separately, which is very troublesome and will cause the material temperature to rise. For this reason, we propose a fine aggregate pre-cooling device for brick production. Utility Model Content
