And high-temperature liquid/heat conducting oil is introduced into the heating coil, and the materials in the drying kettle are dried. The heating coil 400 adopts a half-tube cross-section structure, so that the heating area between the coil and the drying kettle can be increased, and the heat transfer efficiency is high. Meanwhile, compared with a jacket type heating structure, the heating coil 400 is arranged on the outer side wall of the drying kettle and the bottom of the drying kettle, so that the overall stress of the drying kettle can be improved, the overall structural strength of the drying kettle is increased, and the drying kettle can be well suitable for a large-capacity and large-volume material drying device.
Referring to fig. 3, 4 and 6, the stirring mechanism 100 in the present embodiment includes a stirring shaft 110 extending into the drying kettle in a vertical direction, and a stirring paddle assembly is provided on the stirring shaft 110, where the number of the stirring paddle assemblies provided on the stirring shaft may be set as required.
In this embodiment, as a set of stirring paddle assemblies, the set of stirring paddle assemblies includes stirring paddles 121, 123 for stirring materials and discharge paddles 122, 124 for discharging materials; wherein the stirring blades 121, 123 and the discharging blades 122, 124 are each disposed obliquely to the bottom surface of the drying pot, and when the stirring shaft is rotated clockwise or counterclockwise, the stirring blades 121, 123 and the discharging blades 122, 124 are inclined in opposite directions to the direction of inclination of the discharging blades 122, 124 with respect to the bottom surface of the drying pot in the same rotation direction, and as shown in fig. 4 and 6, the stirring blades 121, 123 are inclined to the right side and the discharging blades 122, 124 are inclined to the left side.
