Rotary nanofiber preparation device

Abstract

The invention discloses a rotary nanofiber preparation device. A charging vessel in the rotary nanofiber preparation device includes nozzles, an upper rectangular shell and a lower rectangular shell,wherein the upper rectangular shell and the lower rectangular shell are of hollow structures, the upper rectangular shell and the lower rectangular shell are connected up-down into a whole structure,a junction position of the upper rectangular shell and the lower rectangular shell are connected with the nozzles, and the inner parts of the upper rectangular shell and the lower rectangular shell together form an in-device cavity in communication with the nozzles. The in-device cavity is internally provided with a fiber source, an upper heater is arranged above the top of the upper rectangular shell, a lower heater is arranged below the bottom of the lower rectangular shell, the bottom of the lower rectangular shell is connected to a rotary shaft through a bottom bearing, a heat conducting chamber is formed in the position, close to the lower heater, on the rotary shaft, and buffer layers are arranged at the top and the side part of the heat conducting chamber correspondingly. The designdoes not need to apply a high-voltage electric field and is not subject to conductivity constraints, the heating effect is good, the production efficiency is high, and the adjustability is high.

Description

technical field [0001] The invention relates to textile equipment, in particular to a rotary nanofiber producing device, which is particularly suitable for improving the production efficiency of textile nanofibers. Background technique [0002] Nanofibers refer to ultrafine fibers with a diameter of tens to hundreds of nanometers, which have unique advantages that other fibers cannot possess, such as very large specific surface area, ultrafine porosity, and good mechanical properties. In recent years, nanofibers have been widely used in textile materials, tissue engineering scaffolds, filter media, nanosensors, composite materials and other fields. [0003] The preparation of nanofibers has attracted the attention of experts and scholars at home and abroad. So far, there are many methods for preparing nanofibers, such as stretching method, microphase separation, template synthesis, self-assembly, electrospinning, etc. Among them, the electrospinning method is characterized ...

AI Technical Summary

Problems solved by technology

However, electrospinning also has the following inherent defects: firstly, a high-voltage electric field needs to be applied during the preparation process, and the cost is high, and safety issues require additional attention; secondly, the production efficiency is low; thirdly, the solution requires a certain proportion of solvent to make the solution have a certain conductivity, will cause pollution
