An energy-saving impregnation dryer

Abstract

The invention discloses an energy-saving impregnation dryer, which comprises an uncoiling mechanism, a primary impregnation mechanism, a primary drying mechanism, a secondary impregnation mechanism, a secondary drying mechanism, a cooling mechanism, a deviation correction mechanism, a traction mechanism and a stacking mechanism, and an adhesive film Start from the uncoiling mechanism and pass through the primary impregnation mechanism, the primary drying mechanism, the secondary impregnation mechanism, the secondary drying mechanism, the cooling mechanism, the deviation correction mechanism and the stacking mechanism, wherein the primary drying mechanism includes a primary drying chamber, a primary drying device, condensing chamber, hot air outlet, condensing device, impregnating agent collecting device and outer casing. After adopting the above structure, an impregnating agent recovery device is installed at the primary drying mechanism, which not only recovers part of the impregnating agent taken out of the primary impregnating mechanism and returns it to the primary impregnating mechanism, but also improves the temperature fluctuation of the system by changing the device. The production process tends towards a stable environment.

Description

technical field [0001] The invention belongs to the technical field of immersion dryers, and in particular relates to an energy-saving immersion dryer. Background technique [0002] At present, impregnation machinery has been more and more widely used in people's daily life, especially the secondary impregnation and drying production line is mainly used for furniture boards, melamine veneer paper, decorative surface sheets for reinforced composite floors, wear-resistant paper, Plywood kraft paper, decorative paper; production of kraft paper for cement templates and production of alkali-free glass fiber cloth, cotton cloth, wood pulp paper, and copper foil. [0003] Patent application number 201120414760.9 discloses a double-cone rotary vacuum dryer, which can realize the function of supplying liquid materials to the barrel of the double-cone rotary vacuum dryer under vacuum and rotation. The double-cone rotary vacuum dryer includes a cylinder, a hollow shaft, a vacuum tube ...

AI Technical Summary

Problems solved by technology

[0005] Secondary impregnation and drying machinery has particularly strict requirements on the environment, such as the temperature or humidity in the environment. Due to the drastic changes in the external temperature, the yield of the product will be greatly reduced, and the quality cannot be guaranteed; at the same time, the service life of the machine will be seriously reduced. In addition, most of the heat generated by the heating and drying device in the secondary impregnation and drying machine is directly discharged into the air, resulting in energy loss. At the same time, it also increases the temperature of the secondary impregnation and drying machine itself. changes, which are extremely detrimental to the production process
