Drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is a schematic diagram of the internal structure of the present invention.
Wherein: 1. the device comprises a box body, 2, a vacuum cavity, 3, a vacuum pump, 4, an air extraction pipeline, 5, a heating device, 6, a partition board, 7, a heat insulation space, 8, a temperature sensor, 9, a storage board, 10, a display, 11, a controller, 12, a box door, 13 and a filtering device.
Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 and 2, the improved low-temperature vacuum oven comprises an oven body 1, a vacuum cavity 2 is arranged in the oven body 1, a vacuum pump 3 is arranged on the oven body 1, and the vacuum pump 3 is communicated with the vacuum cavity 2 in the oven body 1 through an air extraction pipeline 4. And starting the vacuum pump 3 to pump the vacuum cavity 2 communicated through the pumping pipeline 4, so that the vacuum cavity 2 is in a vacuum state. A filtering device 13 is arranged between the air pumping pipeline 4 and the vacuum pump 3. Therefore, the water vapor and impurity gas can be effectively filtered during air extraction, and the gas is prevented from entering the vacuum pump 3, so that the pump body is damaged. The bottom of the vacuum cavity 2 is provided with a heating device 5, and the heating device 5 is internally provided with an electric heating wire for heating and drying the object. A plurality of clapboards 6 are arranged between the box body 1 and the vacuum cavity 2, and the clapboards 6 form a heat insulation space 7 between the box body 1 and the vacuum cavity 2, so that heat can be better prevented from being radiated outwards. A temperature sensor 8 and a plurality of object placing plates 9 are arranged in the vacuum cavity 2. The temperature sensor 8 is connected with a display 10 on the outer surface of the box body 1 through a connecting wire. The outer surface of the box body 1 is also provided with a controller 11, and the controller 11 is respectively connected with the heating device 5 and the temperature sensor 8 through connecting wires. One side of the box body 1 is provided with a box door 12, and the box door 12 is a sealing door. The arrangement of the sealing door not only facilitates the storage and the taking out of the articles in the box body 1, but also ensures the vacuum environment in the vacuum cavity 2 in the process of heating and drying the articles.
The use process comprises the following steps: the door 12 is opened first, and the articles to be heated and dried are put on the object placing plate 9. The box door 12 is closed, the vacuum pump 3 is started to vacuumize the vacuum cavity 2 in the box body 1, then the heating device 5 is started through the controller 11, and the objects on the object plate 9 are heated and dried, and the vacuum cavity 2 is in a vacuum state, so that the heat transfer efficiency is more uniform and more dispersed, and the drying efficiency and the drying effect are greatly improved. During the heating and drying process, the temperature sensor 8 feeds back the temperature in the vacuum chamber 2 to the display 10 for displaying, and the controller 11 can control the heating device 5 to adjust the temperature in the vacuum chamber 2 within the optimal heating and drying range.
