Description

A single-layer rapid dryer equipment for architectural ceramics

technical field

The utility model relates to the technical field of architectural ceramic dryer equipment, in particular to a single-layer rapid dryer equipment for architectural ceramics.

Background technique

At present, architectural ceramic products (such as clay panels, glazed tiles, split bricks, etc.) that are formed by wet methods at home and abroad have a remarkable feature, that is, the moisture content of the green body is very high, generally around 16%. The process requires that the moisture content of the green body when it enters the roller kiln for firing is ≤1%, therefore, the reasonable drying of the green body moisture is very important. The products formed by wet method first enter the multi-layer rapid dryer for a quick drying, and then enter the single-layer dryer in front of the kiln through the conveying line for secondary drying. If the traditional ordinary dryer is used to dry the water, the drying cycle will be shorter. Generally, it must reach 20 hours. The reason is that the temperature of the ordinary dryer comes from the waste heat of the kiln, and the temperature can only reach about 180°C. Therefore, if a common kiln front single-layer dryer is used to dry the green body for wet-formed products, it will seriously affect the increase in output, and it is difficult to meet the needs of production.
