[0021] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 A baking oven with good heat insulation effect includes a frame 1, a conveyor belt mechanism 10, and a unit drying section. The frame 1 is internally installed with a conveyor belt mechanism 10 for conveying materials. The top of the frame 1 is installed with a plurality of unit drying sections. The conveyor belt mechanism 10 is used to convey materials. The materials are dried in sections in the plurality of unit drying sections.

[0022] The unit drying section includes a lower outer furnace plate 3 and an upper outer furnace plate 4, a lower inner furnace plate 13, and an upper inner furnace plate 16. The cross-sections of the lower outer furnace plate 3 and the lower inner furnace plate 13 are U-shaped, the lower outer furnace plate 3 is fixed on the frame 1, and the cross-sections of the upper outer furnace plate 4 and the upper inner furnace plate 16 are N-shaped. The upper outer furnace plate 4 is fixed above the lower outer furnace plate 3, and the upper inner furnace plate 16 is fixed above the lower inner furnace plate 13. Both ends of the lower outer furnace plate 3 and the lower inner furnace plate 13 are connected by a first concave boss 18 that fits together with each other, which can improve the sealing effect of the lower outer furnace plate 3 and the lower inner furnace plate 13 and reduce energy loss. Both ends of the upper outer furnace plate 4 and the upper inner furnace plate 16 are connected by a second concave boss 17 that fits together with each other, which can improve the sealing effect of the upper outer furnace plate 4 and the upper inner furnace plate 16 and reduce energy loss. An air hood 14 is installed inside the furnace plate 16, and a blower 7 is installed inside the air hood 14. Through holes are provided on both sides of the air hood 14. Two guide plates 12 symmetrically arranged about the through holes are fixed on the air hood 14. Baffles 9 are fixed at both ends of the upper inner furnace plate 16. A heater 8 is installed inside the upper inner furnace plate 16. The heater 8 is located between the two guide plates 12. A perforated plate 15 is fixed to the bottom of the guide plate 12. When the blower 7 is working, the blower 7 inhales air through the through holes, and the gas flows through the heater 8 and is heated, and then is discharged through the air hood 14 to dry the material. The gas inside the upper inner furnace plate 16 flows back to the heater 8 through the perforated plate 15 for heating. The two guide plates 12 guide the gas, and the gas circulates again from the through holes and is blown into the interior of the upper inner furnace plate 16 by the blower 7, which is very energy-saving.
