Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1-5, an oven structure device comprises a framework 1, a liner 2, two inlet/outlet ports 6, a fixing plate 7, an upper layer partition plate 8, a lower layer partition plate 9, and a plurality of ventilation drying structures 10, wherein the framework 1 is of a cuboid structure, the liner 2 is inserted into the framework 1, the outer diameter of the liner 2 is smaller than the inner diameter of the framework 1, a plurality of elastic sealing strips are arranged between the framework 1 and the liner 2, the two inlet/outlet ports 6 are symmetrically arranged in the middle of the left and right ends of the liner 2, the fixing plate 7 is respectively connected with the framework 1 and the left and right ends of the liner 2 through bolts, an air inlet 3 is arranged at the lower side of the middle of the side wall of one side of the liner 2, an air return port 4 is arranged right above the air inlet 3, and an observation door 5 is arranged in the middle of the side wall of the liner 2, which is opposite to the air inlet 3 and the air return port 4, the utility model discloses a ventilation drying device, including inner bag 2, upper baffle 8, lower floor's baffle 9, air intake 3, air return 4, air return, two inlet/outlet 6 and middle part cavity intercommunication, a plurality of ventilation holes have evenly been seted up on upper baffle 8, evenly vertically a plurality of ventilation gaps have been seted up on lower floor's baffle 9, a plurality of ventilation drying structure 10 is fixed respectively and is set up the ventilation gap department at lower floor's baffle 9, ventilation drying structure 10 includes two crooked pieces 10.1, the one end of crooked piece 10.1 and the last fixed surface of lower floor's baffle 9 are connected, and the other end passes the ventilation gap of lower floor's baffle 9, two crooked pieces 10.1 symmetry set up, and the middle gap that leaves "V" style of calligraphy.

When the device is used, firstly, the fixing plate 7, one end of the liner 2 and the framework 1 are fixedly connected through bolts, one end of the liner is fixed, the other end of the liner is free, then a glass fiber wire is fed from the inlet/outlet 6 at one end and enters the middle cavity of the liner 2, and is fed out from the inlet/outlet 6 at the other end, the external circulating fan is started, air blown out by the fan is heated by the heater and then enters the lower cavity of the liner 2 from the air inlet 3, hot air in the lower cavity upwards enters the middle cavity of the liner 2 through a ventilation gap between two bent sheets 10.1 on the lower partition plate 9, meanwhile, the glass fiber wire is heated and air-dried, hot air in the middle cavity continuously upwards enters the upper cavity of the liner 2 from a ventilation hole of the upper partition plate 8 and finally comes out from the air return port 4 to form internal circulation of the hot air, and the drying condition of products in the liner 2 can be observed in real time through the observation door 5 in the heating and drying process;

in the heating process, the inner container 2 is heated to expand, and in the transverse direction, because one end of the inner container 2 is fixed by the fixing plate 7 and the other end is free, the inner container can extend to the free end in the transverse direction, so that the inner stress generated by the heating expansion is released, and when the temperature is reduced, the inner container contracts to the original state;

in the temperature rise process, the inner container 2 expands under the principle of expansion with heat and contraction with cold, the structural size is further lengthened, the thermal displacement Delta L is formed, and the increase of the thermal displacement Delta L along with the temperature rise can be obtained through calculation according to the thermal expansion rate.
