Description
Technical Field
[0001] The utility model belongs to the technical field of hot-dip galvanizing drying equipment, in particular to a hot-dip galvanizing drying device with a uniform drying structure. Background Art
[0002] Existing hot-dip galvanizing drying devices have some significant shortcomings in terms of uniform drying, which affects the quality of the coating and production efficiency. First, the drying device often has the problem of uneven temperature distribution, resulting in uneven drying effects on the surface of the plated parts. This shortcoming is usually caused by unreasonable layout of heating elements or poor design of the hot air circulation system. Specifically, the deviation of the position of the heating element or insufficient hot air circulation will cause the local temperature to be too high or too low, thus affecting the consistency of drying. Secondly, the drying speed is difficult to control, some parts may be over-dried, while other parts may be under-dried. This is because the drying device lacks a precise temperature control system and cannot adjust the heating time and temperature according to the shape and thickness of the plated parts. In addition, the drying device has large thermal inertia and slow temperature response. It takes a long time to adjust the temperature, which makes it difficult to adapt to rapid changes in the production process.
[0003] Conventional countermeasures include optimizing the layout of heating elements, improving the hot air circulation system, adopting zoned temperature control technology and increasing temperature control accuracy. However, these methods also have certain disadvantages. Optimizing the layout of heating elements and improving the hot air circulation system require large-scale modifications to existing equipment, which is costly and complex to construct, and may affect production progress. Although zoned temperature control technology and increasing temperature control accuracy can improve drying uniformity, they require complex control systems and sensors, which increases the complexity of the equipment and the difficulty of maintenance. In addition, the effects of these improvement measures may be affected by many factors in actual production, such as the size, shape and material of the plated parts, making it difficult to fully guarantee the consistency of drying. Therefore, we hope to design a hot-dip galvanizing drying device with a new structure to solve this problem. Utility Model Content
