Description

Drying device for ultra-thick high-strength steel Technical Field The utility model relates to the technical field of steel plate water-based anti-corrosion primer spraying, in particular to a drying device for ultra-thick high-strength steel. Background The automatic spraying technology of the ultra-thick high-strength steel plate is one of important development directions in the field of steel structure manufacturing in recent years, and is mainly applied to the fields of buildings, bridges, ships, ocean engineering, engineering machinery and the like. The ultra-thick high-strength steel is widely applied to engineering machinery manufacturing due to the excellent mechanical property and durability. However, its surface treatment (e.g., preservation, storage, etc.) places higher demands on the spray and drying techniques. In the prior art, a drying device for a steel structure spraying system is proposed in patent 201920965252.6. The steel structure sprayed with paint is conveyed into the baking frame body through a conveying belt, and the infrared rays generated by the upper infrared baking plate and the lower infrared baking plate enable the surface temperature of the steel structure to rise, so that the paint is dried. However, the traditional drying mode is natural air drying or single hot air drying, which takes longer time, and the high-strength steel plate may cause local overhigh or insufficient temperature due to the difference of thermal conductivity, which affects the curing effect of the coating Disclosure of utility model The utility model aims to provide a drying device for ultra-thick high-strength steel, which has two forms of radiation drying and thermal convection drying for steel plates, can switch a switch, adopts different drying forms for different steel plates, and saves energy. In order to achieve the above purpose, the drying device for the ultra-thick high-strength steel comprises a convection drying circulation system heating device, wherein a fresh air fan is fixedly connected to one side of the convection drying circulation system heating device, the lower end of the convection drying circulation system heating device is fixedly connected with a drying chamber body, a system framework is fixedly connected to the inner side of the drying chamber body, and an infrared radiation system is fixedly connected to the inner side of the system framework. According to the ultra-thick high-strength steel drying device, a convection drying circulation system return air pipe and a convection drying circulation system blast pipe are symmetrically and fixedly connected between the convection drying circulation system heating device and the system framework. According to the ultra-thick high-strength steel drying device, a plurality of convection drying circulation system air supply filters are uniformly arranged at the lower end of the infrared radiation system. According to the ultra-thick high-strength steel drying device, an exhaust gas fan is arranged on one side of the return air pipe of the convection drying and circulating system. The beneficial effects are that: The inside top of drying chamber body sets up the infrared radiation board, the infrared radiation face is dried above the steel sheet downwards, the infrared radiation board is independent system, can dry above the steel sheet alone, set up hot convection blast pipe in the drying chamber below, set up the return air pipe in drying chamber top one side, the drying chamber outside sets up heating device, it dries the steel sheet bottom through the blast pipe after the hot-blast heating through heating device, the blast pipe is equipped with filter equipment and guarantees the air supply cleanliness factor, also prevent that the overspray from dripping into the tuber pipe inside simultaneously, start hot convection stoving when spraying two-sided steel sheet, make it possess both radiation stoving and hot convection stoving two types simultaneously to the steel sheet, but the change over switch, adopt different stoving forms to the spraying mode of different steel sheets, the energy is saved.
