Abstract

This utility model relates to the field of drying equipment technology, and in particular to a zoned flow-guided hot air circulating drying oven, including a drying chamber, an exhaust pipe, and a return pipe. The drying chamber is divided into several drying spaces. A sealing door is hinged to the front of the drying chamber. A blower is installed on the top of the drying chamber. The upper end of the exhaust pipe is connected to the air outlet of the blower. The lower ends of the exhaust pipe and the return pipe are connected to all drying spaces in the drying chamber. A drying circulation assembly for drying the return hot air is installed on the top of the drying chamber. The upper end of the return pipe is connected to the air inlet of the blower through the drying circulation assembly. A heating rod is installed inside the exhaust pipe, and a heat-conducting pipe is installed between the exhaust pipe and the return pipe. By dividing the drying chamber into multiple independent drying spaces, and with the control valve at the outlet pipe's branch port, the high-temperature airflow can be precisely and directionally distributed, avoiding heat energy waste caused by a single space, solving the problem of heat energy imbalance during mixed drying, and optimizing the drying process and energy utilization.
