Description

Technical Field

[0001] This utility model relates to the field of paper product processing, specifically a dryer for paper product manufacturing. Background Technology

[0002] The main purpose of drying is to remove excess moisture from the paper through high temperatures, bringing it to a specified moisture content to ensure its physical properties such as strength, smoothness, and gloss. Simultaneously, drying prevents deformation and mold growth during subsequent processing or storage. Drying is a crucial step in paper product production, directly impacting the final quality and performance of the paper products. Traditional paper dryers typically use electric heating or hot air drying. Paper products are placed in a drying chamber, and heating elements or hot air remove moisture, achieving the drying purpose. However, during the drying process, the evaporation of moisture from the paper products generates a large amount of hot steam. In traditional technologies, this hot steam is often directly released into the atmosphere without effective utilization.

[0003] Specifically, existing paper product dryers typically focus only on drying efficiency and speed, neglecting the secondary utilization of the hot steam generated during the drying process. This hot steam contains a significant amount of thermal energy; direct release would not only waste energy but also potentially have negative environmental impacts. Furthermore, the release of hot steam increases the humidity inside the drying chamber, which may affect the drying efficiency and quality of the paper products. Therefore, we propose a dryer for paper product manufacturing. Utility Model Content

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present utility model provides a dryer for paper product manufacturing, having the following beneficial effects:

[0017] Improve drying efficiency: By designing a drying component including an electric heating drying plate and a hot air duct structure, this dryer can achieve double-sided drying of paper products. The electric heating drying plate directly heats the paper products, and the hot air duct structure utilizes the hot steam generated during the drying process to preheat and dry the paper products again through the air jet nozzles in the heat storage box. This double drying method significantly improves the drying efficiency.

[0018] Energy saving and resource recycling: The hot air channel structure and heat storage tank design in this patent realize the recycling of hot steam. The hot steam generated during the drying process is sucked out by the suction fan, transmitted to the heat storage tank through the pipe, and then sprayed out through the air nozzle to preliminarily heat and dry the paper products. This way not only reduces energy waste, but also improves resource recycling, in line with the green and environmentally friendly production concept.

[0019] Optimizing the drying environment: The use of suction fans not only helps to quickly remove the hot steam generated inside the drying box, preventing the formation of a humid environment inside the drying box that affects the drying efficiency of the paper products, but also maintains air circulation inside the drying box, providing a drier and more uniform drying environment for the paper products.

[0020] Improving the quality of paper products: Since the dryer can achieve uniform drying of both sides of the paper products and has high drying efficiency, it can significantly improve the quality of the paper products, making them smoother and more even, meeting higher production requirements.
