Abstract

The invention relates to an electrostatic spinning device for preparing nano-fiber in batch. The device comprises a liquid storage groove which stores a spinning solution, a spinning system is arranged in the liquid storage groove, a receiving device is arranged above the spinning system, and a spray nozzle rotation system and a high-voltage electrostatic generator are connected to the spinning system; the spinning system comprises a center shaft which is arranged in the liquid storage groove, a spray nozzle is arranged on the center shaft, adjustment sleeves are arranged between the spray nozzle and the center shaft, and two ends of the center extend out of the liquid storage groove and are connected with the spray nozzle rotation system and the high-voltage electrostatic generator respectively. According to the electrostatic spinning device, the production efficiency of nano-fiber preparation is high, the controllability is good, the problems can be solved that the spinning solution volatilizes easily in the spinning process and a traditional spray nozzle is easily blocked, and the batch production by using electrostatic spinning for preparing the nano-fiber can be achieved.

Description

technical field [0001] The invention relates to an electrospinning device for preparing nanofibers, in particular to an electrospinning device capable of preparing nanofibers in batches, and belongs to the technical field of electrospinning. Background technique [0002] In recent years, due to the convenient operation of electrospinning technology, a wide range of raw material sources, and the ability to spin at room temperature, electrospun nanofibers have small fineness, high porosity, and large specific surface area, and their application range is very wide. At the same time, due to the small diameter of nanofibers, the size effect is very significant, and it shows many novel properties in light, heat, electricity, magnetism, etc., and has a wide range of application values ​​in the fields of biomedicine, textile clothing, filtration, and biomedicine. Therefore, electrospinning to prepare nanofibers has attracted the attention of more and more researchers. Electrospinni...
