Sand core drying furnace system and design method

The invention relates to a sand core drying furnace system and a design method. The sand core drying furnace system comprises a hot air system, a control system, an exhaust system and a tray. The hot air system comprises a nozzle and a drying furnace; the nozzles comprise vector nozzles; the drying furnace is divided into a drying furnace preheating section, a drying furnace heating section and a drying furnace cooling section; vector nozzles are mounted on two sides of a heating section of the drying furnace; the control system comprises a 3D intelligent identification system camera, a PLC and a processor; a camera of the 3D intelligent identification system collects product information, a PLC receives the product information, a processor processes the product information, and the angle of a vector nozzle is correspondingly adjusted. The exhaust system is arranged above the heating section of the drying furnace; a conveying roller way is arranged in the drying furnace, and the tray runs on the roller way, en
