Description

Technical Field

[0001] The utility model relates to the technical field of ovens, in particular to a triple oven. Background Art

[0002] An oven, as the name implies, is a device that heats up an object and raises the temperature inside the oven to dry it. Existing ovens are mainly divided into two categories: household ovens and industrial ovens. In the production process of aluminum-plastic film, an oven is required to dry the film for its maturation effect. Under normal temperature conditions, the temperature is raised to 70°C, and the humidity inside the oven is only 5-10%. During the maturation process, the glue will harden due to too low humidity, which will have an adverse effect on the punching of the aluminum-plastic film. Therefore, steam is required to maintain a certain humidity in the oven.

[0003] In the existing technology, in order to avoid excessive pressure in the oven, the steam needs to be discharged after entering the oven and being humidified. At this time, a large amount of heat energy and water vapor in the oven will be taken away, resulting in a waste of resources. Utility Model Content

[0004] The utility model aims at the defects of the prior art and provides a triple oven, which adopts the structure of a coupled oven and sends the heat energy and water vapor discharged from the oven to the next oven for reuse, thus avoiding the problem of waste of resources.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The first oven discharges steam carrying a large amount of heat energy and water vapor to the second oven for secondary utilization.
