Description

technical field [0001] The invention relates to a multi-helix electrospinning device, in particular to an electrospinning device capable of preparing nanofibers on a large scale, and belongs to the technical field of electrospinning. Background technique [0002] In recent years, due to the convenience of operation and wide source of raw materials, electrospinning technology can be spun at room temperature, and the nanofiber materials produced by electrospinning have small diameter, high porosity, large specific surface area, and a wide range of applications. Etc. At the same time, due to the small diameter of nanofibers, the size effect is very significant, and they show many novel properties in terms of light, heat, electricity, and magnetism. Filtration (such as gas filtration, liquid filtration and personal protection, etc.), catalysis (such as photocatalysis, electrode catalysis and enzyme catalysis, etc.), energy and many other fields have shown very important applica...

Problems solved by technology

[0003] However, the traditional electrospinning technology uses a single needle as the spinneret. In the process of electrospinning, the single needle often encounters clogging, which seriously affects the continuous operation of the electrospinning process and also lays a foundation for the subsequent cleaning. work brings some difficulty

In addition, the production efficiency of single-needle electrospinning is very low (0.01-0.1g / h), which is only for laboratory use and cannot meet the application requirements of nanofiber materials in composite materials, protective clothing, filtration and other fields

In summary, the disadvantages of traditional needle-type electrospinning devices have seriously restricted the industrial application and promotion of nanofibers.
