Description

Technical Field

[0001] The utility model relates to the technical field of vacuum drying ovens, in particular to a vacuum drying oven filtering device used for the production of covalent organic framework materials. Background Art

[0002] Covalent organic framework is a new type of organic material, which is composed of organic units with controllable structure connected by covalent bonds. COF is characterized by high adjustability and controllability. Its physical and chemical properties, such as pore size, surface area, mechanical strength, chemical stability, etc., can be adjusted by synthesizing different types of organic units. Due to these characteristics, COF is widely used in separation, catalysis, adsorption, optoelectronics and energy. After the production of covalent organic framework materials, due to the moisture and humidity contained in the production process, they need to be dried in a vacuum drying oven.

[0003] The covalent organic framework material is placed in a vacuum drying oven for drying. During drying, the vacuum drying oven needs to be evacuated. After drying, gas needs to be introduced to avoid excessive internal negative pressure, which makes it inconvenient to open the oven door. When the gas is transported, external air will enter, and filtering equipment is needed for filtering. However, as the covalent organic framework material is dried multiple times, there will be more dust on the filtering equipment. The filtering equipment is fixedly installed, which is not convenient for cleaning and collecting dust. Therefore, a vacuum drying oven filtering device for the production of covalent organic framework materials is proposed. Utility Model Content
