[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Please see Figure 1-4 A vacuum drying oven includes a body 1, a base 2 installed on the inner wall of the body 1, a first drive motor 3 installed on the inner wall of the base 2, a flange 4 installed on the outer wall of the first drive motor 3, a turntable 5 installed on the inner wall of the flange 4, a placement platform 6 installed on the top of the turntable 5, a placement rack 7 installed on the top of the placement platform 6, and a storage basket 8 installed on the outer wall of the placement rack 7. The first drive motor 3 is connected to the flange of the turntable 5, and the turntable 5 is welded to the placement platform 6. The turntable 5 is movably connected to the base 2, and the placement platform 6 forms a rotating structure with the base 2 through the turntable 5. When using the device, the storage basket 8 is placed in the slots at different heights on the placement rack 7. By starting the first drive motor 3, the placement platform 6 on the turntable 5 is rotated, thereby driving the storage basket 8 on the placement rack 7 to rotate, which facilitates the rotation of the items in the storage basket 8, making it easier to heat the items evenly and improve drying efficiency.

[0026] Please see Figure 1-4 A vacuum drying oven has sliders 9 installed on both sides of a placement platform 6. A second drive motor 10 is installed on the inner wall of the oven body 1, and a bolt rod 11 is installed on the outer wall of the second drive motor 10. A support frame 12 is installed on the outer wall of the bolt rod 11. The bolt rod 11 and the support frame 12 are movably connected, and the bolt rod 11 and the support frame 12 form a rotating structure through the second drive motor 10. The sliders 9 and the bolt rod 11 are threadedly connected, and the placement platform 6 forms a sliding structure with the oven body 1 through the bolt rod 11. When using the device, after the items are dried, the oven door is opened, and the second drive motor 10 is started to rotate the bolt rod 11, causing the sliders 9 to slide, thereby pushing the base 2 out of the oven body 1, and then the items are taken out. This process does not require the staff to reach into the oven body 1, avoiding burns to the staff's hands from the residual heat inside the oven body 1 and improving safety.

[0027] Please see Figure 1-4 A vacuum drying oven is provided, wherein a heater 13 is installed on the inner wall of the oven body 1, a vacuum pump 14 is installed on the top of the oven body 1, a first pipe 15 is installed on the outer wall of the vacuum pump 14, a gas collection box 16 is installed on the outer wall of the oven body 1, a second pipe 17 is installed on the outer wall of the gas collection box 16, a fan 18 is installed on the side wall of the oven body 1, a fixing bolt 19 passes through the interior of the fan 18, the fan 18 is threadedly fixed to the oven body 1, and the second pipe 17 is connected to the oven body 1. The first pipe 15 is welded to the gas collection box 16 and is connected to the gas collection box 16. When the device is in use, the hot waste gas generated by the vacuum pump 14 enters the gas collection box 16 through the first pipe 15 for energy recovery. Then the fan 18 can be started to blow the hot gas stored in the gas collection box 16 into the oven body 1 through the second pipe 17, transferring the hot gas to the fresh air or other media that need to be preheated in the oven body 1, thereby reducing the overall energy consumption and improving the energy utilization rate.

[0028] Working principle: First, move the device to a suitable position. Then, place the items to be dried in the storage basket 8. Position the storage basket 8 according to the height of the items, and then close the door. Adjust the temperature and vacuum level. After adjustment, start the heater 13 and vacuum pump 14 to dry the items. Simultaneously, start the first drive motor 3 to rotate the placement platform 6 on the turntable 5. The rotation of the placement platform 6 causes the items in the storage basket 8 on the placement rack 7 to rotate, ensuring heat is evenly distributed on the items. During operation, the waste heat generated by the vacuum pump 14... The gas enters the gas collection box 16 through the first pipe 15 for centralized collection. At the same time, the fan 18 can be started to blow the hot gas stored in the gas collection box 16 into the box body 1 through the second pipe 17. After the item is dried, the box door is opened, and the box body 1 is started to rotate the bolt rod 11. The rotation of the bolt rod 11 causes the slider 9 to slide, moving the base 2 outside the box body 1. Then, the storage basket 8 is taken out from the placement rack 7 to retrieve the finished item. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
