Description

Technical Field

[0001] The utility model relates to the technical field of paperboard processing, in particular to an energy-saving paperboard drying device. Background Art

[0002] Cardboard, also known as board paper, is a thick paper sheet made of various pulps and composed of interwoven fibers. It can be divided into several categories according to its use, such as packaging cardboard (boxboard, kraft boxboard, etc.), industrial technology cardboard (electrical insulation cardboard, asphalt waterproof cardboard, etc.), construction cardboard (felt paper, fireproof cardboard, etc.) and printing and decorative cardboard (font cardboard, cover cardboard, etc.). Cardboard is widely used in packaging, transportation and box making. At present, the humidity of newly produced cardboard is generally relatively high, so it is not easy to break during the production process. Before use, some cardboards may be too humid in the rough environment, making their surfaces wet, so a drying device is needed to dry the cardboard. However, most of the traditional devices are fixed drying methods, which may cause uneven heating of the cardboard in the drying room, especially the side of the cardboard surface facing the drying equipment is prone to overheating, while other parts may not be dry enough. Therefore, such a fixed drying method cannot fully dry the entire space in the device, resulting in excess heat in some areas and insufficient heat in other areas, thereby reducing the drying efficiency. In addition, in the traditional drying method, the cardboard can often only receive heat in a static state, which also leads to low heat utilization and low drying efficiency. Utility Model Content
