An impregnation dryer

Abstract

The invention discloses an impregnation dryer, and a second drying mechanism comprises a second drying chamber, a burner, a second heating device, a second condensing chamber, a second hot air outlet, a second condensing unit and a second impregnant collection device. In addition, the second impregnant collection device is arranged at the bottom end of the second drying chamber, and is used to collect an impregnant in the second drying chamber. Through use of the structure, the drying mechanism is provided with the impregnant collection device, part of the impregnant carried out from a first impregnation mechanism is recovered, and returned to the first impregnation mechanism, system temperature fluctuation can be also improved by the device, and the production process tends to be a stable environment. Exhaust in a cooling mechanism is introduced into a gas inlet of the burner for improvement of combustion gas problem of the burner, and by use of waste heat of the exhaust in the cooling mechanism, the impregnation dryer plays the role of energy conservation and emission reduction.

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
