Description

Technical Field

[0001] The utility model relates to the technical field of drying ovens, in particular to a vacuum drying oven with a limiting mechanism. Background Art

[0002] In order to facilitate the storage, transportation and use of materials, the materials need to be dried. Drying refers to the operation of removing water or other moisture from wet materials. It is mainly achieved through convection drying, conduction drying and radiation drying. However, for some materials containing heat-sensitive, easily decomposable and easily oxidized components, the method of drying in the atmospheric environment is no longer applicable, and a vacuum drying oven is required to dry the materials.

[0003] In the prior art, the application number is CN202321464426.3, and the application name is a vacuum drying oven with a limiting mechanism. The technical solution recorded includes a box body and a limiting mechanism. A vent valve is provided on one side of the box body, a control panel and a box door are provided on the outside of the box body, an observation window is installed on one side of the box door, and a drying chamber is provided inside the box body. The vacuum drying oven with a limiting mechanism sets parameters on the control panel, and then starts the motor, so that the motor drives the rotating shaft to rotate, and then the rotating box rotates, and drives the material to rotate for drying, so that the material can be heated evenly, the evaporation rate of water is accelerated, and the drying efficiency of the vacuum drying oven is improved. By placing the tray on one side of the limiting plate, the limiting spring rebounds and drives the connecting rod to push to one side, so that the limiting plate is against the tray, preventing the tray from shaking during the rotary drying process, and improving the stability and practicality of the vacuum drying oven.

[0004] However, there are still some shortcomings in the actual use process. After drying, the temperature of the surface of the object will be high, which is not convenient for taking and placing. For this reason, we have made further improvements. Utility Model Content
