Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of curing ovens, in particular to a curing double-layer oven. Background Art
[0002] Curing ovens are mainly used for drying, curing, heat treatment, temperature tests and other constant temperature heating of products. Convective heat transfer is carried out by using a fan to transfer heat to the products. Conventional ovens mainly use the hot air drying method. First, air is introduced into the heating device, and the heated hot air is introduced into the oven. After the hot air contacts the products, it is discharged from the air outlet of the oven. This direct discharge of hot air will cause heat loss. And because the air needs to be heated first, products with higher requirements for the oven temperature cannot obtain the required oven temperature. In addition, for traditional ovens, the utilization of the internal space of the oven is not sufficient. Due to concerns about poor drying effect in the oven, the utilization rate of the internal space of the oven is low. Therefore, there is a need for a curing double-layer oven that can improve the drying effect in the oven while ensuring the reasonable utilization rate of the internal space of the oven. Summary of the Utility Model
