This utility model relates to the technical field of parts
drying, and in particular to a tunnel-type
drying device, including a base, a
drying mechanism at one end of the base, and a cleaning mechanism at the other end of the base. This tunnel-type drying device, through the arrangement of a drying shell, heating tubes, a first motor, a rotating rod, a
conveyor belt, a guide rod, a connecting seat, a
semiconductor cooler, a cooling fan, an air supply duct, and a
cooling pipe, firstly, the heating tubes are energized and heated. Then, the parts are placed on the
conveyor belt and the first motor is started. The first motor causes the rotating rod to rotate, and the
conveyor belt begins to transport the parts. The parts are transported into the drying shell and dried. When the parts leave the drying shell, the
semiconductor cooler and the cooling fan are activated. The cooling fan blows the
cold air generated by the
semiconductor cooler into the air supply duct. Finally, the
cold air is blown onto the parts through the
cooling pipe to cool the dried parts.
