Description

TECHNICAL FIELD

[0001] The utility model belongs to vacuum drying machine technical field, more particularly to a kind of vacuum drying machine with explosion-proof function. BACKGROUND

[0002] The working principle of vacuum drying machine is mainly based on the phase change principle of water, that is, the boiling point of water is reduced by reducing air pressure, so that the water in the material is rapidly evaporated at a lower temperature. In the vacuum drying process, the material to be dried is first placed in the drying chamber of the vacuum drying machine, then the drying chamber is closed, and the vacuum pump is started to extract the air in the drying chamber to form a certain vacuum degree in the drying chamber. Under vacuum state, the boiling point of water will be greatly reduced, and the moisture in the material will rapidly evaporate at a lower temperature. At the same time, the drying chamber is heated by the heating system to improve the temperature of the material surface, further accelerating the evaporation of moisture. The water vapor evaporated will be discharged from the drying chamber by the vacuum pump, so as to maintain a low humidity environment in the drying chamber and realize rapid drying of the material.

[0003] The sealing surface of the vacuum drying machine may be damaged due to long-term use, wear or improper operation, resulting in a decrease in sealing performance. The damaged sealing surface cannot effectively prevent the leakage of gas or liquid, thereby affecting the vacuum degree and drying effect of the equipment. The sealing material (such as rubber, plastic, etc.) may age due to long-term exposure to high temperature, high pressure or corrosive environment, lose elasticity or develop cracks. The aged sealing material cannot tightly fit the sealing surface, resulting in a decrease in sealing performance. The sealing element may be improperly installed during installation due to non-standard operation, such as not cleaning the sealing surface, not installing the sealing element correctly, etc. Improper installation may result in poor sealing performance, and even may cause damage to the sealing element. When the vacuum drying machine is subjected to uneven extrusion force during operation, the sealing surface may be subjected to additional pressure or tension, resulting in a decrease in sealing performance. Uneven extrusion force may also cause the sealing cover to deform or be damaged, further affecting the sealing performance. UTILITY MODEL CONTENTS
