Abstract

The invention provides a vacuum dryer. The vacuum dryer comprises a tank body, a tank cover and a cavity, wherein the tank cover is arranged on the tank body in a sealing and covering mode and the cavity is defined by the tank cover and the tank body. The tank body comprises a vacuum layer arranged on the outer side and a water bath layer arranged on the inner side of the vacuum layer, and the bottom end of the tank body and the tank cover are provided with a lower precise gas valve and an upper precise gas valve respectively, wherein the lower precise gas valve and the upper precise gas valve are communicated with the cavity. The vacuum dryer can effectively control the temperature in the cavity and keep components of gas in the cavity stable.

Description

technical field [0001] The invention relates to laboratory appliances, in particular to a vacuum dryer capable of stabilizing the internal gas environment. Background technique [0002] Traditional vacuum desiccators are mainly used to vacuum dry stored items or realize vacuum drying functions, but they can no longer meet the growing needs of scientific research experiments. Requirements such as avoiding air inflow during post-cap operations cannot be met by conventional vacuum dryers. Contents of the invention [0003] The invention provides a vacuum dryer capable of realizing gas convection, controlling the index of the gas charged and simultaneously controlling the temperature of the internal environment. [0004] In order to solve the above problems, the present invention provides a vacuum dryer, which includes a tank body, a tank cover with a sealing cover arranged on the tank body, and a cavity surrounded by the tank cover and the tank body. The body includes a vac...
