Description

Technical Field

[0001] This utility model relates to the field of water-based anti-corrosion primer spraying technology for steel plates, and in particular to a drying device for ultra-thick high-strength steel. Background Technology

[0002] Automated spraying technology for ultra-thick high-strength steel plates is one of the important development directions in the steel structure manufacturing field in recent years, mainly used in construction, bridges, ships, marine engineering, and engineering machinery. Ultra-thick high-strength steel is widely used in engineering machinery manufacturing due to its excellent mechanical properties and durability. However, its surface treatment (such as corrosion protection and storage) places higher demands on spraying and drying technologies.

[0003] In existing technologies, such as the drying device for a steel structure spraying system proposed in patent 201920965252.6, a conveying channel is formed between an upper infrared baking plate and a lower infrared baking plate. The steel structure, after being sprayed with paint, is conveyed to the baking rack via a conveyor belt. The infrared rays generated by the upper and lower infrared baking plates raise the surface temperature of the steel structure, drying the paint. However, traditional drying methods, such as natural air drying or single hot air drying, are time-consuming, and the difference in thermal conductivity of high-strength steel plates may lead to localized excessively high or insufficient temperatures, affecting the coating curing effect. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for ultra-thick high-strength steel, which can simultaneously perform both radiation drying and hot convection drying on steel plates. It is switchable and can adopt different drying methods for different coating methods of steel plates, thus saving energy.

[0005] To achieve the above objectives, a drying device for ultra-thick high-strength steel is provided, including a convection drying circulation system heating device. A fresh air fan is fixedly connected to one side of the convection drying circulation system heating device, and a drying chamber is fixedly connected to the lower end of the convection drying circulation system heating device. A system frame is fixedly connected to the inner side of the drying chamber, and an infrared radiation system is fixedly connected to the inner side of the system frame.

[0006] According to the drying device for ultra-thick high-strength steel, the convection drying circulation system heating device and the system frame are symmetrically and fixedly connected by a convection drying circulation system return air pipe and a convection drying circulation system supply air pipe.

[0007] According to the drying device for ultra-thick high-strength steel, multiple convection drying circulation system air filters are uniformly arranged at the lower end of the infrared radiation system.

[0008] According to the drying device for ultra-thick high-strength steel, an exhaust fan is installed on one side of the return air duct of the convection drying circulation system.

[0009] Beneficial effects:

[0010] An infrared radiation panel is installed at the top inside the drying chamber, drying the steel plate from the downward direction. The infrared radiation panel is an independent system that can dry the steel plate separately. A hot convection air supply duct is installed at the bottom inside the drying chamber, and a return air duct is installed on one side of the top of the drying chamber. A heating device is installed outside the drying chamber. Hot air is heated by the heating device and then circulated through the air supply duct to dry the bottom of the steel plate. The air supply duct is equipped with a filter to ensure the cleanliness of the supplied air and to prevent overspray paint from dripping into the air duct. When spraying double-sided steel plates, hot convection drying is activated, so that it can simultaneously perform both radiation drying and hot convection drying on the steel plate. The switch can be turned on and off to use different drying methods for different steel plates, saving energy.
