Abstract

The invention provides an internal stirring assembly of an aerogel aging device. The stirring assembly comprises a main stirring impeller and circulating stirring impellers, the main stirring impellerand the circulating stirring impellers are positioned through fixing sleeves and are arranged at intervals through a limiting sleeve; the two circulating stirring impellers are oppositely arranged symmetrically, when the stirring main shaft rotates, the stirring main shaft pushes the sol to the main stirring impeller while stirring the sol, feeding is carried out, the sol convection is generated,and the stirring effect is enhanced, crushing teeth are arranged on the inner side of a first stirring blade of the main stirring impeller, and when stirring is carried out, the small micelles can bebroken, the aging process can be conveniently carried out, and the aging efficiency can be improved.

Description

technical field [0001] The invention relates to the field of airgel production and application, in particular to a stirring component in airgel aging equipment. Background technique [0002] Airgel is a product obtained by drying the solvent in the gel while maintaining the integrity of the gel skeleton structure. It is an amorphous low-density material with a nanoporous structure. Silica airgel, also known as "blue smoke" and "solid smoke", is the lightest solid material known so far, and it is also the material with the best thermal insulation performance so far. It is known as "the magic material that changes the world" ". [0003] At present, the production process of silica airgel generally needs to go through two processes of sol-gel and drying. Among them, in the process of sol-gel, after the preparation and fusion of the sol are completed, aging equipment is usually required for aging. Polycondensation forms a network gel. [0004] During this process, there are o...
