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.

Example Embodiment

[0019] In order to make the technical solution of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings. Any solution obtained by equivalent replacement of the technical features of the technical solution of the present invention and conventional reasoning shall fall into the protection scope of the present invention.
[0020] As shown in the figure, a stirring assembly in an aerogel aging equipment includes a stirring spindle 1 and a stirring blade 2. The stirring spindle 1 includes a connecting end 3 and a rotating end 4, and the section of the connecting end 3 In a square shape, the rotating end 4 is cylindrical, an external thread is provided between the connecting end 3 and the rotating end 4, and a fixed sleeve 5 is provided. The mixing blade 2 includes a main mixing impeller 6 and a circulating mixing impeller 7;
[0021] The main mixing impeller 6 is composed of a plurality of elliptical arc-shaped first mixing blades 8, the plurality of elliptical arc-shaped first mixing blades 8 are uniformly distributed in an elliptical shape, and both ends of the main mixing impeller 6 are connected with the connecting sleeve 9 , The connecting sleeve 9 fits with the connecting end 3 with a square cross-section, and the main mixing impeller 6 is arranged in the middle of the rotating end 4 through the connecting sleeve 9;
[0022] The number of the circulating mixing impeller 7 is two, which are symmetrically arranged on both sides of the main mixing impeller 6 and separated by a limit sleeve 10, and the number of the fixed sleeve 5 is two, which are arranged on the mixing spindle 1 through external threads. There is also a limit sleeve 10 between it and the circulating stirring impeller 7. With the fixing sleeve 5 tightened, the main stirring impeller 6 and the circulating stirring impeller 7 are positioned at the same time;
[0023] The inner surface of the elliptical arc-shaped first mixing blade 8 is provided with crushing teeth 11, and the number of crushing teeth 11 is multiple and evenly distributed;
[0024] Further, the circulating stirring impeller 7 is a spiral stirring impeller, and the two circulating stirring impellers 7 are arranged oppositely;
[0025] Further, the limiting sleeve 10 fits with the connecting end 3 with a square cross section;
[0026] Further, the crushing tooth 11 has a quadrangular pyramid shape or a triangular pyramid shape.
[0027] The aerogel aging equipment provided by the present invention includes a stirring assembly including a stirring spindle and a stirring blade. The stirring blade includes a main stirring impeller and a circulating stirring impeller. The main stirring impeller and the circulating stirring impeller are positioned by a fixed sleeve and pass through a limit. Set at intervals, the two circular stirring impellers are arranged relatively symmetrically. When the stirring spindle rotates, it pushes the sol to the main stirring impeller while stirring the sol for feeding, and generates sol convection, strengthening the stirring effect. The inside of the first mixing blade is provided with crushing teeth, which can break down small micelles while mixing, which facilitates the aging process and improves the aging efficiency.
[0028] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Any person skilled in the art can easily think of changes or changes within the technical scope disclosed by the present invention. All replacements should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
